The Short Answer
Every grid-tied solar system in University Park requires both a building permit and an electrical permit, plus a utility interconnection agreement with Oncor Electric. There are no size exemptions.
University Park, as a small municipality within the Dallas metroplex, has adopted the 2015 International Building Code and NEC 2017 with Texas amendments, and enforces them through the City of University Park Building Department. Unlike some larger Dallas suburbs that have streamlined solar review under Texas SB 379 exemptions (same-day issuance for systems under 25 kW), University Park does NOT offer expedited review — all solar permits go through standard plan review, typically 3-4 weeks. The city's flat $500 permit fee (building + electrical combined) is fixed regardless of system size, which is favorable for larger systems but means even a 3 kW residential array pays the same as a 10 kW system. Critically, University Park sits in Oncor Electric Delivery's service territory, not ERCOT retail choice; this means your interconnection agreement must be filed with Oncor before the city will issue final approval, a step that often surprises homeowners who assume city approval comes first. The city requires both a structural engineer's report for any roof-mounted system over 4 lb/sq ft (nearly all modern panels) and proof of rapid-shutdown compliance per NEC 690.12 before electrical rough inspection. Ground-mounted or carport systems skip the structural roof eval but must show setback and easement compliance with the city's platted lot lines.

What happens if you skip the permit (and you needed one)

University Park solar permits — the key details

The city of University Park enforces NEC Article 690 (solar photovoltaic systems) and Article 705 (interconnected power production) as adopted by the State of Texas, with no local amendments that relax the rules. This means every system — even a tiny 3 kW array — must have a rapid-shutdown mechanism (NEC 690.12) that de-energizes the DC array within 3 seconds of grid loss, verified by a licensed electrician at rough and final inspection. The city's Building Department issues a combined Building/Electrical permit ($500 flat fee) after plan review, which typically takes 10-15 business days. You cannot begin work until that permit is in hand. Roof-mounted systems must include a structural engineer's report confirming that the combined weight of panels, racking, and snow load does not exceed the roof's rated capacity; the city enforces this per IBC 1510 and will not schedule framing inspection without the report. Ground-mounted systems in University Park often trigger setback reviews because the city's platted lots in many neighborhoods are narrow (60–75 feet wide), and solar arrays must be set back at least 10 feet from the front property line, 5 feet from side lines, and clear of utility easements. Battery storage systems (ESS) over 20 kWh require a separate Fire Marshal review and may trigger additional permits; systems under 20 kWh are treated as part of the electrical permit.

University Park's unique advantage is that the city offers a flat $500 permit fee regardless of system size, which is lower than nearby Dallas ($400–$600 sliding scale based on valuation) and significantly cheaper than Plano or Arlington (which charge 1–2% of project cost). However, the city does not offer online plan submission — you must submit paper drawings (3 copies) to the Building Department in person at City Hall, Monday–Friday 8 AM–5 PM, or by mail to the address below. This paper-based process adds 3–5 days to the timeline compared to jurisdictions like Frisco that accept PDF uploads. The city also requires proof of a pre-filed interconnection application with Oncor Electric before it will issue final approval; this is a critical step that often surprises DIY homeowners. Oncor's standard interconnection timeline is 10–15 business days, but you must initiate the application yourself — the city does not submit it on your behalf. If you skip this step and the city inspector finds that Oncor has no record of your system, the permit cannot close and net metering will not be activated.

Structural and electrical inspections happen in sequence. The city's electrical inspector will schedule a rough-in inspection after the structural engineer's report is filed (for roof systems) or after framing is complete (for ground systems). At rough-in, the inspector verifies that the DC disconnects, AC disconnects, grounding, and conduit labeling all match the permit drawings and comply with NEC Article 690. Common rejections at rough-in include missing or improperly labeled conduit, conduit fill exceeding 40% of diameter (NEC 300.17), improper breaker sizing for the inverter (should be 125% of rated output), and missing labels on all combiner boxes and junction points. The rapid-shutdown test is performed at rough-in and again at final: the inspector pulls the rapid-shutdown breaker and verifies that the array de-energizes within 3 seconds using a clamp meter. If your system has string inverters (as opposed to a single larger inverter), each string's rapid-shutdown device must be labeled on the diagram and verified independently. After rough-in passes, you can energize the system and connect to the grid, but net metering is not active until final inspection and Oncor's witness inspection occur (Oncor can take another 10–15 days to schedule). Final inspection includes verification that all conduit is properly secured, that the AC/DC disconnect handles are labeled, and that the main breaker or service entrance labeling is updated to reflect the new load.

University Park sits in a 2A–3A climate zone (depending on exact latitude; the city center is 2A), which means minimal snow load but high wind exposure during hurricane season (June–October). The city's code does not adopt the most current wind speed maps, so roof structural analysis must assume 120 mph sustained winds per the 2015 IBC; this is higher than some Texas municipalities that have adopted 2021 IBC (140 mph). Ground-mounted systems in University Park require concrete footings that extend below the frost line (6–12 inches in the Dallas area, but the city code conservatively requires 12 inches minimum) and must be set 10 feet from the front property line. Carport-mounted systems are becoming popular in University Park because they avoid the roof structural report requirement; however, the carport structure itself must be engineered if it's a new build and certified by the homeowner's engineer before inspection. The city does not exempt carport solar from electrical permitting — only the structural roof-loading requirement is waived.

Timeline and next steps: Once you have your permit in hand, you should immediately file your interconnection application with Oncor Electric (available at oncor.com/generation or by phone at 1-888-313-8876) to avoid bottlenecks. Structural inspection (if roof-mounted) occurs first; plan 1–2 weeks for the report if you haven't already hired an engineer. Electrical rough-in inspection typically follows within 5–7 days of a completed install; Oncor's witness final inspection can take another 2–3 weeks after the city's final inspection. Total timeline from permit issuance to net-metering activation is typically 6–10 weeks. The city's Building Department does not track Oncor's progress; you must monitor both processes independently. If either the city or Oncor rejects your submission, expect an additional 1–2 weeks per resubmission round.

Three University Park solar panel system scenarios

Scenario A
8 kW roof-mounted grid-tied system with string inverters, 24 panels on a clay-tile roof in Highland Park neighborhood (owner-occupied, no HOA restrictions)
You own a 1950s ranch home with a south-facing roof in University Park's Highland Park district, and you want to install an 8 kW system (24 × 400 W LG Neon panels) with two string inverters (one 5 kW, one 3 kW SMA Sunny Boy) and Rapid Power rapid-shutdown devices on each string. The roof is rated for 20 lb/sq ft dead load, and the solar array will add approximately 3.5 lb/sq ft (panels + racking + ballast), well under the limit. You must hire a PE-licensed structural engineer in Texas to certify that your existing roof framing can support the combined dead + live + snow + wind load (assuming 120 mph sustained wind per City of University Park code); this report costs $400–$800 and takes 1–2 weeks to obtain. Once you have the structural report in hand, you submit the solar permit package to the City of University Park Building Department (3 paper copies: architectural drawings showing panel layout, electrical one-line diagram with all DC/AC disconnects labeled, rapid-shutdown schematic, and the structural engineer's signed report). The $500 permit fee is due at the time of application; you can pay by check or card. Plan review takes 10–15 business days. Once approved, you will receive a Notice to Proceed and can begin installation. Before you energize the system, you must file the Oncor interconnection application (Form DERCM-1 or DERCM-2, depending on whether you choose an expedited or standard 5-business-day interconnection window); Oncor charges $0 for residential grid-tied systems. Oncor typically approves within 10 business days and sends you an executed Interconnection Agreement. You then call the City of University Park Building Department to schedule electrical rough-in inspection; the inspector verifies conduit fill, grounding (at least #6 copper or #8 aluminum continuous from each rapid-shutdown device to the service entrance bonding point per NEC 690.45), and that your inverter's 125% breaker (in this case, 12.5 A for the 5 kW inverter and 7.5 A for the 3 kW unit) is installed correctly. Typical rough-in inspection fee is included in the $500 permit. At rough-in, the inspector performs the NEC 690.12 rapid-shutdown test by pulling the manual DC disconnect and measuring that the array voltage drops to under 80 V within 3 seconds; this must be done on both string inverter circuits. Once rough-in passes, you can close both the AC and DC disconnects and begin grid export. Oncor schedules their witness final inspection after the city's electrical final is complete; the Oncor inspector verifies the meter socket, confirms the main panel labeling shows 'Solar' or 'PV System' on the breaker, and witnesses net-metering activation, which takes about 30 minutes. Total timeline: 6–10 weeks from permit issuance to active net metering. Total cost: $500 (city permit) + $400–$800 (structural engineer) + $12,000–$16,000 (equipment + installation labor if contractor-installed; $6,000–$9,000 DIY with all electrical work self-performed by owner under owner-builder exemption). Oncor charges no interconnection fee. No property tax increase in Texas for residential solar under Property Tax Code §11.261.
Permit required | $500 city permit fee | $400–$800 structural engineer report | Roof load ~3.5 lb/sq ft (below 4 lb/sq ft threshold in most cases, but engineering required by city) | Rapid-shutdown test at rough + final | Oncor witness final | No net-metering fee | Total project $13,000–$17,500
Scenario B
5 kW ground-mounted carport system with battery storage (15 kWh LiFePO4), owner-builder, adjacent to setback line near property line in suburban Bluff neighborhood
You want to install a carport-style ground-mounted 5 kW PV system with a 15 kWh battery backup in your Bluff neighborhood home (a newer subdivision with 70-foot lots). The carport is a new structure (not retrofit to an existing carport), and the system includes a 5 kW hybrid inverter (Fronius Primo 5.0-1) that can switch to island mode if the grid fails. Because you are owner-occupied and performing the installation yourself, you qualify for the Texas owner-builder exemption for electrical work on a single-family residence; however, you STILL need the building permit (for the carport structure and the foundation) and the electrical permit (for the PV array and battery system). The carport structure must be engineered by a PE and certified as capable of withstanding 120 mph wind loads and carrying the weight of the panels (approx. 1.2 lb/sq ft) plus snow/ice; this structural engineer report costs $600–$1,000 and takes 2 weeks. The battery enclosure (a standard wall-mounted cabinet) must be sited at least 10 feet from windows and doors per NFPA 855 battery storage standard, and because the system is 15 kWh (above 20 kWh threshold in some jurisdictions but below in University Park's local code), you should verify whether the Fire Marshal requires an ESS review. University Park does NOT have a published ESS permitting process, so you must contact the Building Department before starting design. Assuming the Fire Marshal review is waived (under 20 kWh threshold or deemed residential), you submit the carport building permit (3 copies: foundation plan showing 12-inch frost-line footings per City code, structural engineer's signed carport framing plan, and wind-load certification). The carport building permit costs $500 (flat fee, same as the PV system); this is separate from the electrical permit. Plan review takes 10–15 business days. Once approved, you can begin carport construction and foundation work. You will need a city inspection of the carport framing (structural inspection) before you can attach the PV racking. Simultaneously, you submit the electrical permit package (PV one-line diagram, battery integration schematic, rapid-shutdown schematic, and proof of owner-builder status — a notarized statement that you are the owner-occupant). The electrical permit is another $500. Once the carport framing inspection passes and the electrical permit is approved, you can install the PV array and battery cabinet. Before energizing, you file the Oncor interconnection application (which now includes battery-backed export rules; Oncor may require a grid-support agreement if your battery can export during grid-normal conditions, or may require your system to discharge-only during outages — this varies by Oncor's current policy and can take 15–20 days to clarify). For the final inspection, the city's electrical inspector verifies the rapid-shutdown mechanism, conduit fill, grounding, battery cabinet ventilation (per NEC 706 for energy storage systems), and the hybrid inverter's anti-islanding relay (NEC 705.16). The battery cabinet's temperature and humidity monitoring (if required by the battery manufacturer) is verified at inspection. The Oncor witness final inspection now includes confirmation of the export-control settings in your hybrid inverter — whether it's programmed for 'discharge only during outages' or 'export 50% of stored energy during grid-normal hours' — and verification that your meter has been reprogrammed to handle bidirectional flow if export is permitted. Total timeline: 8–12 weeks (longer than Scenario A due to carport construction delay + Oncor's battery-specific review). Total cost: $500 (carport building permit) + $500 (electrical permit) + $600–$1,000 (carport structural engineer) + $12,000–$18,000 (carport framing + solar equipment, DIY labor) + $8,000–$15,000 (battery system labor and equipment). Total project: $21,000–$34,500. Note: If the Fire Marshal requires an ESS permit for the 15 kWh battery, add 2–4 weeks to the timeline and $200–$500 in fees.
Building permit (carport) $500 | Electrical permit (PV + battery) $500 | Structural engineer (carport) $600–$1,000 | Owner-builder exemption applies to electrical labor only | Rapid-shutdown + battery monitoring inspections | Oncor battery-export-control verification | Ground-mounted, 10-foot setback from front line required | 15 kWh battery under Fire Marshal review threshold (verify locally) | Total project $21,000–$34,500
Scenario C
3.6 kW roof-mounted system on rental investment property (not owner-occupied), with licensed contractor installation and battery storage waived; located in historic district overlay with architectural review board (ARB) approval required
You are an investor who owns a rental property in University Park's historic district (a requirement triggered by lots platted before 1960 and designated on the city's historic district map). Any exterior modification, including solar panels on the roof, requires Architectural Review Board (ARB) approval before the building permit can be issued. This is a University Park-specific local requirement that does NOT apply to non-historic homes and is a critical delay point that many investors overlook. You have hired a licensed electrical contractor (necessary because owner-builder exemption only applies to owner-occupied residential property; rental properties do NOT qualify) and a solar installer to design a 3.6 kW system (10 × 400 W panels + one 3.6 kW string inverter). Before you submit the building permit to the City of University Park, you must submit the ARB application (available from the city's website or in person at City Hall) with architectural renderings showing the panel placement, color, and tilt angle, and confirming that the panels are not visible from the street (or are minimized in visibility). The ARB application typically costs $50–$100 and takes 2–4 weeks to review (ARB meets monthly, so if you miss the submission deadline by even a few days, you could wait 5 weeks for the next meeting). Once the ARB approves the solar design, you receive an ARB Certificate of Appropriateness, which you then attach to your building permit application. The city's building permit review then proceeds normally (10–15 business days), and the $500 permit fee is due. Structural inspection (roof load evaluation by engineer, $400–$800) is mandatory because this is a roof-mounted system. Electrical rough-in inspection occurs after roof installation is complete, with rapid-shutdown testing per NEC 690.12. Because the property is a rental and not owner-occupied, Oncor will require a copy of the property owner's authorization (typically a title deed or property tax record) before activating net metering, which adds 5 business days to the Oncor verification process. Total timeline: 10–16 weeks (4–6 weeks for ARB alone, plus normal permit review). Total cost: $500 (city permit) + $50–$100 (ARB application) + $400–$800 (structural engineer) + $8,000–$12,000 (contractor labor + equipment for 3.6 kW system). Total project: $8,950–$13,400. Note: If the contractor's insurance or bonding lapses, Oncor may refuse the interconnection until proof of renewed bonding is provided; verify contractor credentials 2 weeks before the final inspection to avoid last-minute delays.
Architectural Review Board (ARB) approval required — 4–6 weeks | ARB application fee $50–$100 | City building permit $500 | Structural engineer $400–$800 | Licensed contractor required (owner-builder exemption NOT applicable to rental property) | Roof-mounted, 3.6 kW system | Rapid-shutdown + contractor bonding verified | Oncor net-metering requires property owner authorization | Total project $8,950–$13,400

University Park's paper-based permit process and why it delays solar projects by 5–10 days compared to Dallas-area neighbors

Unlike larger Dallas suburbs such as Plano, Frisco, and Arlington, which accept online PDF submissions and issue same-day or next-day permit approvals for systems under 25 kW, University Park maintains a paper-based permitting system. You must print three copies of your permit drawings (architectural, electrical one-line, and structural report for roof systems), bind them, and submit them in person to the City of University Park Building Department at City Hall (address below) during business hours (Monday–Friday 8 AM–5 PM, closed holidays). The city does not accept email submissions, faxes, or scanned PDF uploads. This means that if you email your drawings to the city at 5:01 PM on a Friday expecting Monday processing, you will instead be told to resubmit in person, losing 48 hours. The plan review queue moves in order of receipt, not by priority; complex projects with missing information can be bumped to the end and re-queued after corrections, adding 5–10 additional days.

The city's building plans examiner (typically one or two staff members covering all building types — residential, commercial, mechanical, solar) reviews your application against the 2015 IBC and NEC 2017 with Texas amendments. If there are plan deficiencies (missing grounding diagram, missing rapid-shutdown schematic, incomplete structural report, or conduit sizing errors), the city sends a written Request for Information (RFI) via US mail, adding 3–5 days for delivery, another 3–5 days for the applicant to respond, and then re-entry into the queue. Many Dallas-area contractors now pad solar timelines by an extra 2 weeks when quoting University Park projects specifically to account for this paper-based friction. Digital-first cities like Plano issue permits within 5 business days; University Park's realistic timeline is 15–21 business days.

Homeowners and small contractors often ask if they can drive to City Hall, submit in person, and get verbal feedback while they wait. The answer is no; the examiner will accept the application but will not provide immediate plan review. You will be told to check back in 10–15 business days or wait for a phone call. Some applicants have saved 3–5 days by hand-delivering the package and asking the front-desk staff to log the receipt time and date, creating a paper trail for follow-up questions, but this is not a guaranteed process — it relies on staff discretion. If you want to expedite, you can call the Building Department directly (number below) and ask if the examiner can prioritize your solar application, but the city has no formal expedited track, so this is a courtesy request with no guarantee.

Oncor Electric Delivery's interconnection agreement and why University Park homeowners must initiate it separately (the city does not file it for you)

A common and costly mistake: homeowners believe that the City of University Park's electrical permit approval automatically means the grid interconnection is approved. This is false. The city and the utility (Oncor Electric Delivery) are separate entities with different timelines and approval criteria. The city's electrical permit verifies that your system meets NEC Article 690 (PV system safety); Oncor's interconnection agreement verifies that your system meets Oncor's grid voltage, frequency, anti-islanding, and export-control requirements. The city will issue you a final electrical permit, but Oncor will not activate net metering until their own approval is complete. You must file Oncor's interconnection application yourself; the city does not do this on your behalf.

Oncor's standard interconnection form is the DERCM-1 (for systems under 10 kW) or DERCM-2 (for systems 10–25 kW). You can request the form from Oncor's website (oncor.com/generation) or by calling 1-888-313-8876. The form requires your service account number (found on your Oncor electric bill), the system size in kW, the inverter model and serial number, the rapid-shutdown device model, and your contractor's or installer's name and license number. Oncor's review timeline is 10–15 business days for a straightforward residential grid-tied system, but if there are any questions about your system's anti-islanding settings or your home's existing electrical panel capacity, it can stretch to 20–30 days. Once Oncor approves, they will mail you an executed Interconnection Agreement; you must then provide a copy to the City of University Park Building Department before the final electrical inspection can be scheduled. If you forget this step and call for final inspection without Oncor's approval, the inspector may notice (or may not), but Oncor will physically come to your home and disconnect your meter if they discover net metering has been activated without an executed agreement, a costly and embarrassing situation.

For battery storage systems (ESS), Oncor's interconnection requirements become more complex. If your battery system can export power during normal grid conditions (not just during outages), Oncor requires a battery-specific interconnection agreement that specifies export limits, voltage support functions, and frequency response settings. This can add 10–15 additional business days to Oncor's review. Many homeowners are surprised to learn that Oncor may require their battery inverter to be programmed in 'discharge-only' mode, meaning the battery can power the home during an outage but cannot send power back to the grid. This limits the financial benefit of the battery (no export revenue), but it is a Oncor requirement in some service territories. Verify Oncor's current battery export policy before you size your system; you can call Oncor's Generation Interconnection team at the number above and ask about their residential battery export requirements. University Park homeowners in Oncor's territory should assume that grid support functions (frequency response, voltage regulation) are NOT permitted without an explicit written agreement, so design conservatively.

Common questions

Do I need a permit for solar panels if I'm just replacing my roof and adding panels at the same time?

Yes. Even if the panels are part of a roof replacement project, you need separate electrical and building permits for the solar system. The roof replacement itself may qualify for a roofing permit (if required by the city's code), but the PV array and its DC/AC disconnects, conduit, grounding, and inverter must be permitted as electrical work under NEC Article 690. University Park requires both a building permit (for the mounting structure) and an electrical permit (for the electrical components) even if they are installed simultaneously. Timeline: expect 15–21 business days for plan review of the combined roof + solar application, assuming structural engineer's report is included.

I hired a contractor and they said they would 'handle the permitting.' Do I need to verify that they've actually submitted the application to Oncor?

Yes. Many contractors submit the city's building permit but forget or delay the Oncor interconnection application. You should verify in writing (email) that your contractor has submitted Form DERCM-1 or DERCM-2 to Oncor at least 2 weeks before the planned final inspection. Ask your contractor for a copy of the Oncor application receipt or a screenshot confirming Oncor's case number. If the contractor has not submitted it by that date, you can file the Oncor application yourself directly; do not wait for the contractor. Oncor's review is independent of the city's, and delays in one do not pause the other.

What if my home is in University Park's historic district — does that add more permits or delays?

Yes, significantly. If your home is in the historic district (generally lots platted before 1960), you must obtain Architectural Review Board (ARB) approval before the city will issue a building permit for the solar system. The ARB application takes 4–6 weeks because the board meets monthly and reviews applications in batches. You must submit architectural renderings showing the panel placement, color, and street visibility. Even if your engineer and electrical drawings are perfect, the ARB can request design modifications (e.g., moving panels to the back of the roof, changing the color of the racking, or lowering the tilt angle for visibility reasons). Plan for an additional 4–6 weeks of ARB review before city plan review even begins. Non-historic homes in University Park skip this step entirely.

My property is a rental, not owner-occupied. Can I use the owner-builder exemption to save on contractor labor?

No. The Texas owner-builder exemption for electrical work applies only to owner-occupied residential properties. If you are an investor renting the property, you must hire a licensed electrical contractor to design and install the system. The city and the utility both verify ownership status via deed and will not accept owner-builder certification if the property is titled as a rental investment or corporation. Expect to pay full contractor labor rates for the electrical design and installation.

Can I install the panels myself if I'm an owner-occupant, or do I need to hire a licensed electrician?

You can perform the mechanical installation (racking, panel mounting, conduit routing) yourself as the owner-builder, but the electrical connections — including DC combiner boxes, inverter wiring, AC disconnect installation, and grounding — must be performed by a licensed electrical contractor or by you if you hold a valid Texas electrician's license. If you do not hold a license, you can run the conduit and route the wires, but a licensed electrician must make all connections and sign off on the system before the city's electrical rough-in inspection. Many homeowners hire a contractor for the rough-in only (typically 4–8 hours of labor) after they have completed the mechanical installation themselves. Verify with the city's electrical examiner if there are any specific tasks that the owner-builder can perform without a license; the city's interpretation may vary from the state law.

How long does net metering take to activate after the city's final inspection is approved?

Oncor's final inspection and net-metering activation takes an additional 2–4 weeks after the city's final electrical inspection. Oncor will schedule their own witness inspection, which includes verification of your meter socket, breaker labeling, and anti-islanding settings. After Oncor's inspection, they reprogram your meter to allow bidirectional flow (export and import). You can use solar power immediately after the city's final inspection, but you will only receive billing credits for exported power once Oncor's meter reprogramming is complete. Do not expect net metering to be active on the same day as the city's final inspection; assume 2–4 weeks of additional waiting.

Does University Park offer any tax breaks or rebates for solar installation?

No. University Park itself does not offer property tax exemptions, rebates, or expedited permitting for residential solar. Texas state law (Property Tax Code §11.261) prohibits municipalities from taxing solar systems as property improvements for 10 years if the system generates power for on-site use. However, this is automatic under state law and does not require a special city exemption. Oncor Electric does not offer rebates for grid-tied systems in the residential sector (they do have rebates for commercial demand-response programs, but not for rooftop PV). You may qualify for the federal Investment Tax Credit (ITC) of 30% of system cost if the system is placed in service by December 31, 2032; this is a federal benefit, not a city benefit, and you should consult a tax advisor. Some solar financing companies offer zero-down leasing or power-purchase agreements (PPAs), but these are private financial products, not city programs.

What happens if I apply for a permit but never install the system — do I lose the permit fee?

Yes. University Park's $500 permit fee is non-refundable once the permit is issued. If you obtain the permit but then decide not to install the system (or change your mind after 2 years), the permit expires and the fee is forfeited. You cannot carry over the permit to the next calendar year or transfer it to a different property. If you later decide to install the system, you must file a new permit application and pay the $500 fee again. Most homeowners hold the permit for 6–12 months before installation, so plan your permit application timing accordingly — do not apply for the permit until you have finalized design and financing.

My system is 25 kW (larger than typical residential). Does University Park treat it differently?

University Park does not have a published threshold for when systems exceed residential limits, but systems over 10 kW begin to enter the 'small commercial' category under NEC Article 705 and may trigger additional utility requirements. Oncor's interconnection form for systems over 25 kW shifts from DERCM-2 to a more detailed interconnection agreement (DERCM-3 or a full Distributed Energy Resource Agreement), which requires 20–30 days of utility review instead of 10–15 days. The city's building permit fee remains a flat $500, so larger systems are a good value from the city's perspective, but Oncor's timeline and requirements increase significantly. If you are considering a system over 25 kW, contact Oncor's Generation Interconnection team before filing the city permit to understand Oncor's review timeline and any required studies (e.g., short-circuit analysis or protection coordination study). The city's examiner may also require a more detailed electrical design for larger systems, so allow 20–25 business days for city plan review instead of the standard 15 business days.

If the city denies my permit application, can I appeal or resubmit?

Yes. If the city issues a denial (not a Request for Information asking for corrections, but an outright disapproval), you have the right to appeal to the City of University Park's Board of Adjustments per the city's municipal code. An appeal typically involves a written request within 15 days of the denial, followed by a hearing before the board (which takes another 2–4 weeks to schedule). Most denials at the plan review stage are actually RFIs — the examiner believes the deficiency can be corrected. If you receive an RFI, resubmit the corrected drawings within the deadline (typically 15 days) to stay in the current review queue. If you receive an actual denial, ask the examiner in writing why the system was rejected (e.g., 'rapid-shutdown mechanism does not comply with NEC 690.12' or 'roof structural capacity insufficient per engineer's report'). Most denials can be resolved by redesigning the system to address the deficiency and resubmitting. A full appeal to the Board of Adjustments is rare for solar permits and adds 6–8 weeks to the timeline.
