The Short Answer
A full bathroom remodel in College Park requires a permit if you're moving fixtures, adding circuits, installing new ventilation, or changing walls. Surface-only updates (tile, vanity swap in place, faucet replacement) do not require a permit.
College Park, unlike some neighboring jurisdictions, enforces Maryland's statewide adoption of the 2015 International Residential Code with local amendments that tighten bathroom-specific inspections. The City of College Park Building Department requires permits for any fixture relocation, new electrical circuits, exhaust fan installation, or wall modification — and critically, the city's online permit portal requires you to upload a full set of plan sheets (floor plan, plumbing schematic, electrical one-line) BEFORE the application is even accepted, not after submission like some Maryland cities. This means you cannot submit a rough sketch and iterate; you need engineered drawings or a contractor's sealed plans upfront. College Park's plan review typically takes 2–3 weeks, and the city requires a separate rough-plumbing inspection before drywall closeout, which adds 1–2 weeks to the schedule if you skip it. Lead-paint hazard compliance is mandatory for any pre-1978 home (College Park was extensively developed in the 1950s–1980s), which adds disclosure and containment costs that homeowners often overlook.

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

College Park full bathroom remodel permits — the key details

College Park requires a permit for nearly all full bathroom remodels because most gut remodels involve fixture relocation, electrical upgrades, or plumbing modifications. The Maryland Plumbing Code (based on the 2015 IRC) requires permits for any work that changes the drain-waste-vent system, moves a toilet, tub, or sink, or adds a new exhaust fan; College Park Building Department enforces this strictly. The city also requires GFCI protection on all bathroom branch circuits per IRC E3902, and any new circuit work triggers a full electrical permit review. The one major exemption: if you are replacing a toilet, faucet, or vanity in the exact same location with no plumbing-line changes, no new electrical outlets, and no tile removal, College Park does not require a permit. However, the moment you move that toilet to a new corner, relocate the sink to face the window, or add a heated towel rail on a new circuit, you are in permit territory. The city's permit application must include a scaled floor plan showing existing and proposed fixture locations, a one-line electrical schematic identifying all circuits affected, and a plumbing schematic showing trap-arm lengths and vent routing — missing any of these will result in a rejection notice within 5 business days.

One critical College Park quirk: the city adopted the 2015 IRC with amendments in 2019 and has NOT yet updated to the 2021 or 2024 cycles, so some energy codes and ventilation standards are slightly behind current code. This is actually a benefit for homeowners — you can use 2015-compliant products and plans without future-proofing to newer standards. However, bathroom-exhaust-fan ductwork must still terminate through an exterior wall or roof (no soffit discharge per IRC M1505.2), and the duct must be insulated if it runs through an unconditioned attic to prevent condensation and mold. College Park's climate (Zone 4A, cold winters, humid summers) makes this particular rule critical; uninsulated ductwork in an attic condensates heavily in winter, drips back into the bathroom, and violates the permit. The code section is IRC M1505.3, and failure to insulate will be flagged during the rough-plumbing inspection and require rework — adding 2–3 weeks to the job if discovered mid-project.

Waterproofing requirements for shower/tub modifications are strict and must be specified in advance. If you are converting a tub to a shower or completely replacing a shower enclosure, IRC R702.4.2 requires a water-resistant barrier behind all tile, and College Park's inspectors specifically verify the waterproofing assembly before drywall closeout. Most contractors use a cement-board base with a liquid or membrane waterproof membrane behind the tile; this must be documented on the permit set with material spec sheets attached. Do not assume the inspector will accept 'standard waterproofing' — the permit application should include the brand and type of cement board (e.g., Durock, Hardiebacker), the membrane product (e.g., Schluter-KERDI, RedGard), and installation photos or shop drawings. If you deviate from the permit-set spec, the inspector can reject the work, and you will be forced to remove tile and re-waterproof at a cost of $1,500–$3,000. Lead-paint testing and containment is mandatory in College Park for any pre-1978 home undergoing renovation; the city requires a lead-safe work practices certification or a clearance test before permit issuance. This typically costs $300–$800 and adds 1–2 weeks if the bathroom was last painted before 1978.

The plumbing trap-arm and fixture-drain layout is a frequent pain point in College Park permits. The code limits the distance from a fixture's P-trap to the vent stack (trap-arm length) to 5 feet for standard drains and 6 feet for toilets under IRC P3105. If you are relocating a sink or toilet away from the existing vent stack, you may hit this limit, especially in older College Park homes with tight layouts. An undersized or overly long trap arm will be flagged during rough-plumbing inspection and require either a new vent line (expensive, potentially invasive) or reworking the fixture location. This is why the plumbing schematic on the permit application must show all trap-arm distances; the city's plan reviewer will often note violations before the job starts. Additionally, the city requires all shower valves to be pressure-balanced or thermostatic per IRC P2704.2 to prevent scalding; the permit must specify the valve type and model number. Failure to specify a compliant valve will result in a plan rejection, and you will be forced to source and install a different valve, delaying the job by 1–2 weeks.

The permit fee in College Park is calculated as 1.5% of the estimated project cost, with a minimum fee of $200 and a maximum of $800 for residential work. A basic bathroom remodel (fixture swap, tile, new vanity, paint) typically runs $8,000–$15,000 and costs $120–$225 in permit fees; a full gut remodel with plumbing relocation and custom shower runs $25,000–$50,000 and costs $375–$750. The fee covers the initial plan review (typically 2–3 weeks) and one set of inspections (rough plumbing, rough electrical, final). Additional inspections or re-inspections after a failed inspection cost $75–$150 each. Owner-builders are allowed in College Park for owner-occupied homes, but you must file a homeowner-builder affidavit, and the city requires you to be present at all inspections to discuss the work with the inspector. General contractors do not need a special license to work in College Park (Maryland does not license GCs at the state level), but they must carry a City of College Park business license (typically $50–$100 annually) and maintain general liability insurance. Payment of permit fees is due at the time of application; the city does not offer payment plans.

Three College Park bathroom remodel (full) scenarios

Scenario A
Sink and toilet relocation, new exhaust fan, existing tile kept — Old Town College Park colonial
You are gutting the existing bathroom in a 1970s colonial off Route 1, keeping the existing tile and tub in place but moving the toilet from one corner to the opposite wall (to make room for a larger vanity) and relocating the sink 4 feet to the left. You are also installing a new exhaust fan with ducting through the attic to the exterior. This project triggers a full permit because you are relocating two plumbing fixtures (toilet and sink), which requires a new vent-stack routing and trap-arm analysis, and you are adding new HVAC (exhaust fan) with electrical work. The permit application must include a floor plan showing old and new fixture locations with measurements, a plumbing schematic with trap-arm distances (the toilet relocation may require reworking the vent stack if the new location is more than 6 feet from the stack, and the sink relocation will need a new drain line and trap assembly). The electrical plan must show the new exhaust-fan circuit (typically a 15-amp dedicated circuit on a 20-amp breaker, or 20-amp circuit depending on fan CFM rating per IRC E3902.11). The duct insulation must be specified as R-4 minimum for Zone 4A attic runs. The rough-plumbing inspection will verify trap-arm compliance and vent routing before walls close; the rough-electrical inspection will check the fan circuit and GFCI compliance. The final inspection will confirm the fan terminates through the exterior wall (not soffit) and the dryer vent is separate. Timeline: 2–3 weeks plan review, 1–2 weeks for rough inspections, 1 week for final. Permit fee: $200–$350 (assuming $12,000–$20,000 estimated cost). Lead-paint testing required if pre-1978 (add $400–$800 and 1 week). Total project cost typically $8,000–$16,000 for materials and labor, plus permit and testing fees.
Permit required | Plumbing relocation | New exhaust-fan circuit | Trap-arm verification | Lead-paint testing (if pre-1978) | Permit fee $200–$350 | Plan review 2–3 weeks | 2 inspections (rough, final) | Timeline 4–6 weeks total
Scenario B
Tub-to-shower conversion, wall tile, heated towel rail on new circuit — Graduate Hills ranch
Your 1965 ranch on the south side has a concrete-slab foundation and a bathtub that you want to convert to a walk-in shower with niche storage and a heated towel rail on a new 240-volt circuit. This is a classic permit case because you are changing the drain (tub drain is typically 1.5 inch, shower pan drain is 2 inch) and adding new electrical (a 20-amp circuit for the towel rail per IRC E3902.9, which requires GFCI protection). The waterproofing assembly is critical: you will need a shower pan liner or pre-formed pan, a 1.5-inch minimum concrete slope for drainage, and wall-tile waterproofing (cement board + liquid membrane or schluter system). The permit must include a waterproofing detail showing the pan construction, membrane type, and tile layout; the city's inspector will specifically ask to see the membrane product and installation before tile is set. The electrical plan must show the 20-amp circuit clearly labeled with overcurrent protection size, wire gauge (12 AWG for 20 amp), and the disconnect location. College Park enforces IRC E3902.11 strictly for bathroom circuits, meaning the new towel-rail circuit cannot share a GFCI device with the vanity circuit (different circuits required). The drain relocation must be verified for trap-arm compliance; if the shower is in the same corner as the old tub, this is usually straightforward, but if you are relocating the shower, the trap arm from the shower pan to the vent stack cannot exceed 5 feet. The rough-plumbing inspection will check the pan slope, drain sizing, and trap routing; the rough-electrical inspection will verify circuit protection and GFCI configuration; the final will confirm waterproofing is in place and tile is sealed properly. Timeline: 2–3 weeks plan review, 1–2 weeks rough inspections, 3–5 days final. Permit fee: $250–$400 (assuming $15,000–$25,000 estimated cost). This project showcases College Park's emphasis on waterproofing detail — a frequent plan rejection. Total project cost typically $12,000–$25,000.
Permit required | Tub-to-shower conversion | Drain-size change | New 20-amp circuit | Waterproofing detail required | Heated towel rail spec | Permit fee $250–$400 | Plan review 2–3 weeks | 3 inspections (rough plumb, rough elec, final) | Timeline 4–7 weeks
Scenario C
Vanity and faucet swap in place, tile refresh, no fixture moves — Berwyn Heights-area townhouse
You are updating a 1990s townhouse bathroom with a new vanity cabinet and faucet, removing and replacing the wall tile around the sink, and adding a new mirror and lighting fixture. You are NOT moving the sink location, NOT changing the drain line (using the same supply and drain stubs), NOT adding any new electrical circuits (the existing outlet and light circuit remain unchanged), and NOT modifying the exhaust fan. This is surface work only and does NOT require a permit in College Park. The vanity swap, faucet replacement, tile removal and re-tiling (same wall area), mirror, and paint all fall under the exempt category per IRC R322 (maintenance and repair). However, if the light fixture swap involves adding a recessed can light in a new location (requiring a new junction box and wire run) or upgrading to a new exhaust fan, a permit would be required. The key test: are you changing the drainage system, electrical circuits, or venting? If no, no permit. If yes, permit required. In this case, you can buy a permit-free vanity combo online, hire any contractor (licensed or not), and have it installed without city involvement. No inspections, no fees, no timeline delays — just DIY or hire a handyman. This scenario illustrates College Park's exemption for true cosmetic work; the city does not require permits for surface-level remodels. However, if the old vanity is mounted to damaged tile or drywall, you may need to patch the wall, which is still exempt. Lead-paint testing is only required if you are removing paint (not tile) and the home is pre-1978; tile removal does not trigger lead-paint rules. Total project cost typically $2,000–$5,000, zero permit fees.
No permit required | Surface work only | Vanity swap (same location) | Faucet replacement | Tile refresh | No circuit changes | No drainage changes | Total cost $2,000–$5,000 | Timeline 2–5 days | Zero permit fees

College Park's waterproofing-detail requirement and why it matters

College Park's position in the Piedmont/Coastal Plain boundary with humid summers and cold winters makes waterproofing a critical failure point. The city's plan reviewers specifically require shower and tub enclosure waterproofing to be documented on the permit application with material spec sheets and installation details; this is a local enforcement emphasis not as strict in all Maryland jurisdictions. IRC R702.4.2 requires a water-resistant barrier, but College Park interprets this narrowly: cement board (minimum 1/2 inch) with a liquid or sheet membrane behind all tile is the baseline. Many contractors assume 'moisture-resistant drywall' (green board) is sufficient, but the city's inspectors will reject this and force removal and re-installation with proper cement board and membrane.

The practical impact: if your permit plans show a waterproofing detail with Schluter-KERDI or RedGard membrane, the inspector approves it quickly (5–10 minutes at inspection). If the plans are vague ('standard waterproofing'), the inspector will ask to see the product and installation method on-site; if the materials don't match the code standard, they will issue a correction notice, and you will be forced to remove tile, re-waterproof, and re-tile — a $1,500–$3,000 setback. This happens in roughly 1 in 4 bathroom permits in College Park that do not specify waterproofing upfront, so the best practice is to include a waterproofing detail in your initial application.

The College Park climate makes this rule sensible: winters drop to 20–30 degrees F, and bathrooms are often the warmest, most humid rooms in the home. Condensation runs heavy, and water will find every gap. A properly waterproofed shower assembly (cement board + membrane + sealed tile grout) lasts 20+ years; a green-board bathroom may see tile failure and hidden mold within 3–5 years. The city's requirement is building a better product, not just checking a box.

Electrical circuits, GFCI, and the permit-portal upload requirement

College Park's permit portal requires you to upload a one-line electrical schematic showing all circuits affected by the remodel BEFORE your application is accepted. This is unusual compared to some Maryland cities that allow verbal descriptions or simple sketches. The city requires this because bathroom electrical code (IRC E3902) is dense: GFCI protection on all 15- and 20-amp bathroom circuits, AFCI protection on lighting and fan circuits, dedicated circuits for each major fixture, and clear labeling of wire gauge and breaker size. By requiring the schematic upfront, the city avoids back-and-forth rejections.

For a typical full bathroom remodel: the vanity/sink circuit must be GFCI-protected (usually a 20-amp circuit with 12 AWG wire); the toilet cannot share a circuit (IRC E3902.4); the exhaust fan gets its own 15- or 20-amp circuit with AFCI protection; and any heating, towel rail, or ventilation fans get separate dedicated circuits. If you are installing a whirlpool tub or sauna, it demands its own 15-amp or 20-amp circuit depending on load. The permit application schematic must show all of this clearly, with breaker sizes and wire gauges labeled. Missing any detail will result in a rejection notice, and you will be asked to resubmit.

A key College Park practice: the city does not accept hand-drawn schematics; they must be typed or computer-generated using a simple electrical-plan tool (even a clear Excel diagram works). This upfront requirement often slows down permitting by 3–5 days because homeowners or contractors do not prepare the schematic before submitting. The best approach: prepare your electrical plan in draft form BEFORE you apply, so you can upload it same-day. If you hire a licensed electrician, they usually prepare this plan and submit the application; if you are owner-builder, you will need to draw it yourself or hire a draftsperson ($150–$300).

Common questions

Do I need a permit if I'm just replacing my toilet, sink, and faucet in the same location?

No permit is required if you are replacing fixtures in their existing locations without relocating drains or adding new electrical circuits. A simple faucet swap, toilet replacement, or vanity cabinet change (using the same supply-and-drain stubs) is classified as maintenance under College Park code and is exempt. However, if you move the fixture to a new location, change the drain size, or add a new supply line, a permit is required. Confirm your plan with the Building Department before starting if there's any doubt.

What is the permit fee for a bathroom remodel in College Park, and when do I pay it?

The permit fee is 1.5% of the estimated project cost, with a minimum of $200 and a maximum of $800 for residential work. A typical full bathroom remodel ($15,000–$30,000) costs $225–$450 in permit fees. Payment is due at the time of application; the city does not offer payment plans. You will receive an invoice when you submit your application, and the permit will not be issued until payment is received.

Can an owner-builder pull a permit for a bathroom remodel, or must I hire a licensed contractor?

Owner-builders are allowed in College Park for owner-occupied homes. You must file a homeowner-builder affidavit at the time of application, and you are required to be present at all inspections. Maryland does not license general contractors at the state level, so a GC license is not required to pull a permit. However, any plumber and electrician working on the project must hold a current Maryland license; you cannot do plumbing or electrical work yourself unless you are a licensed tradesperson. If you hire a contractor, ensure they carry a College Park business license and general liability insurance.

How long does plan review take, and when can work start?

College Park's plan review typically takes 2–3 weeks from application submission. Once the plan is approved (you will receive a stamped copy), work can begin immediately — you do not need to wait for an inspection to start. However, certain phases (rough plumbing, rough electrical, framing) require inspections before the next phase; the inspector must sign off on rough work before drywall and final installation. Failure to call for inspections at the right time can delay the project by several weeks.

What are the most common reasons for permit rejections on bathroom remodels in College Park?

The top rejections are: (1) missing or vague waterproofing details (the inspector needs to see cement board, membrane type, and installation method specified); (2) electrical schematic missing circuit labels, wire gauges, or breaker sizes; (3) trap-arm distances exceeding 5 feet without a secondary vent (the plan must show all trap-arm lengths); (4) exhaust fan duct terminating in a soffit instead of through an exterior wall or roof; and (5) faucet or valve not specified as pressure-balanced or thermostatic. Review the city's recent rejection letters online or call the Building Department to ask about common issues.

If my house was built before 1978, do I need a lead-paint test before starting a bathroom remodel?

Yes, if your home was built before 1978 and the permit involves any wall removal, tile removal, or interior demolition, a lead-hazard assessment is required. College Park requires either a lead-safe work practices certification (your contractor completes EPA RRP training, typically $500–$800 for the job) or a clearance test confirming lead levels after work is complete. The test adds $300–$600 and 1–2 weeks to the timeline. You can obtain a list of certified lead inspectors from the EPA or Maryland Department of Health.

How many inspections does a typical full bathroom remodel require?

A typical full remodel requires 2–3 inspections: (1) rough plumbing (verifies drain routing, trap-arm compliance, and vent stack connection before walls close), (2) rough electrical (checks circuits, GFCI devices, and wire sizing), and (3) final inspection (confirms waterproofing, tile, fixtures, and exhaust fan are installed correctly). If you are also modifying framing or removing walls, a framing inspection is required before drywall. Each inspection takes 20–45 minutes, and you must call ahead to schedule. Missed inspections can delay the project by 1–2 weeks.

Can I convert a bathtub to a shower in College Park without a permit?

No, converting a tub to a shower requires a permit because the drain system changes (tub drains are typically 1.5 inch; shower pans are 2 inch), the waterproofing assembly changes, and plumbing lines may need rerouting. The permit must include a waterproofing detail and a plumbing schematic showing the new drain routing and trap-arm distance. The city's inspector will verify the waterproofing assembly (cement board + membrane) before tile is installed and will conduct a rough-plumbing inspection before walls close. This is one of the most common bathroom remodels and typically takes 4–6 weeks from permit to final approval.

What happens if I start work without a permit and the city finds out?

A stop-work order will be issued, and you will face a $250–$500 fine. Once you stop work, you must obtain a permit retroactively, pay double permit fees (on top of the standard fee), and submit to all required inspections under increased scrutiny. Unpermitted work will also appear on title records and must be disclosed when you sell the home (Maryland's Real Property Disclosure Form requires sellers to report all unpermitted renovations). Lenders and insurers often refuse to cover unpermitted work, so a later claim (bathroom flood, electrical fire) may be denied, potentially costing $15,000–$50,000. It is far cheaper and faster to permit upfront.

If I hire a general contractor, are they responsible for pulling the permit, or do I need to do it?

This depends on your contract with the contractor. Most general contractors include permitting in their estimate and pull the permit themselves; they will ask you for a filled-out application form and may require a signed authorization to act on your behalf. If the contract does not mention permitting, ask explicitly before work begins. As the homeowner, you are responsible for ensuring the permit is pulled, regardless of who pays for it; if the contractor skips it and the city discovers the work, you are liable for the stop-work fine and retroactive permit costs, not the contractor. Always verify that a permit has been issued and posted on-site before allowing work to start.
