The Short Answer
If you're creating a bedroom, bathroom, or true living space in your basement, Cicero requires a building permit plus electrical and plumbing permits. If you're just finishing walls and flooring for storage or utility space without adding fixtures or egress, you may be exempt — but Cicero's Building Department will push back on moisture mitigation regardless.
Cicero enforces the Illinois Building Code (IBC), which Cicero has adopted with local amendments that are stricter than many neighboring Cook County suburbs on two fronts: moisture mitigation and egress documentation. Unlike some smaller suburbs that rubber-stamp basement permits, Cicero's Building Department requires a signed moisture-intrusion inspection report BEFORE plan review if the property has any history of water in the basement — even if you're not adding a bedroom. This is Cicero-specific risk management tied to the city's glacial-till soil and aging storm-sewer infrastructure. Additionally, Cicero requires that any egress window for a basement bedroom be verified on-site during framing inspection by a city inspector before drywall goes up; you cannot self-certify or rely on a third-party inspection report alone. Many homeowners in nearby suburbs (Berwyn, Forest Park, Oak Park) find this stricter than their jurisdictions. The permit fee is typically $200–$500 depending on finished square footage and whether you're adding plumbing or mechanical systems. Plan-review timeline runs 3–4 weeks for straightforward basements, longer if moisture issues require third-party engineering.

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

Cicero basement finishing permits — the key details

Cicero's Building Department uses the 2021 Illinois Building Code (IBC), which is based on the 2021 International Building Code (IBC) with Illinois and Cicero amendments. The core rule is IRC R305.1: any basement space used for living, sleeping, or sanitation must have a ceiling height of at least 7 feet measured from the finished floor to the lowest point of the ceiling (beams, ducts, joists). If you have a ceiling height of 6 feet 8 inches or less, you are limited to storage, utility, or mechanical spaces and cannot legally finish a bedroom, family room, or full bathroom. Cicero's Building Department will measure ceiling height during framing inspection and will red-tag your permit if you fall short. This is non-negotiable and affects hundreds of Cicero basements built before 1950, where joists sit 6 feet 6 inches to 6 feet 8 inches above the slab. The 42-inch frost depth in the Cicero area (part of Cook County's glacial-till zone) also means your footer and any new structural elements in the basement must go below 42 inches; if you're adding a bathroom with a trap or ejector sump, the city will require that the sump be at least 4 feet deep and that the ejector pump discharge line slope upward and vent to grade (IRC P3103.2). Most Cicero basements have poor or no perimeter drainage, so the city's inspectors expect to see evidence of existing sump pumps, interior or exterior perimeter drains, or a vapor barrier retrofit (6-mil polyethylene taped at seams, minimum). If you have documented water intrusion in the past, Cicero will require a licensed engineer's moisture-mitigation report before the permit is even issued — this can add 2–4 weeks and $1,500–$3,000 to your project timeline.

Egress is the single largest code issue in Cicero basement finishing. IRC R310.1 requires that every basement bedroom (and every sleeping room) have an egress window or door that leads directly to grade, open air, or a stairwell leading outside. The window must be at least 5.7 square feet of net opening (3 feet wide × 4 feet tall, minimum), and the sill must be no more than 44 inches above the finished floor. If your basement has a natural window well that's already there, you still need to ensure it meets code: the window well must have a sloped floor drain (no standing water), minimum width of 3 feet, and if it's deeper than 44 inches, a removable ladder bolted inside. Cicero's Building Department requires that you identify and label the egress window(s) on your permit plan AND that a city inspector physically verify the window opening and sill height during framing inspection before drywall is installed. You cannot rely on a window manufacturer's spec sheet or a contractor's word; the city will measure. The cost to add a code-compliant egress window (well, window, drain, and landscaping) runs $2,500–$5,000 per opening. If your basement has no suitable window location, you must install a supplementary emergency egress door (leading to an exterior stairwell or bulkhead) — this costs $4,000–$8,000 but is the only legal alternative. Many homeowners in Cicero are surprised to learn that finishing a basement WITHOUT a bedroom is simpler: a family room, rec room, or wet bar with no sleeping area does not require an egress window and thus skips a major cost and code review. This is a real savings if your plan is flexible.

Electrical work in basement finishing requires a separate electrical permit and inspection. Any new circuits, outlets, or switches in a habitable or wet space (bathroom, laundry) must comply with NEC Article 210 (circuits and outlets) and NEC Article 680 (special locations). In particular, all outlets in a bathroom or laundry room must be on a 20-amp circuit with AFCI (Arc-Fault Circuit Interrupter) protection per NEC 210.12. If you're adding a bedroom, all outlets in that bedroom must also be AFCI-protected per NEC 210.12(B). Outlets within 6 feet of a sink in a laundry or bathroom must have GFCI (Ground-Fault Circuit Interrupter) protection per NEC 210.8. Cicero's electrical inspector will test all GFCI and AFCI outlets with a test meter during rough and final inspection; failures mean you re-wire. Additionally, if your basement is below grade, wet, or subject to seasonal dampness, all new wiring must be in conduit or armored cable (Romex is not allowed in damp locations per NEC 334.12(B)(1)). This adds cost and labor. Cicero does NOT require a licensed electrician to pull the electrical permit if you're the owner and the work is in your owner-occupied home (owner-builder exemption under Illinois law), but you must still pull the permit and pass inspection. Many homeowners attempt DIY electrical and fail the rough inspection on AFCI installation or conduit grounding; hiring a licensed electrician for at least the rough-in is worth the $500–$1,200 investment to avoid rework.

Plumbing permits are required if you're adding a bathroom, toilet, sink, or drain. If you're adding a basement bathroom with a toilet that drains below the main sewer line, Cicero requires an ejector sump pump and discharge line venting to grade (IRC P3103). The sump must be a sealed pit (not an open drain pan) with a pump rated for the load, a one-way check valve on the discharge, and a vent line that extends above grade with a proper roof vent fitting or anti-siphon vent. If you're just adding a laundry sink that drains above the main line, you may not need an ejector pump, but you will need a trap and a vent line (IRC P3103.1). Cicero's plumbing inspector will require that the ejector pump be installed and tested before drywall is hung around it; this means rough-in inspection is critical. The cost of an ejector pump system (pump, basin, discharge pipe, vent, check valve, alarm) runs $1,500–$3,000 installed. If your basement slab has no existing sump pit, the plumber will need to cut and core the slab, install the basin, and backfill — a messy, disruptive job that adds labor. Many homeowners underestimate this cost and are shocked when the plumber quotes $3,500–$4,500 for a 'simple' bathroom addition. Radon mitigation is also a state-level requirement in Illinois: any new or renovated basement space must have radon-mitigation-ready design, meaning a 3-inch or 4-inch PVC vent stack roughed in from under the slab and extending through the roof (or stored for future installation). Cicero's Building Department will require this on the framing plan and verify it during rough inspection. The cost is $300–$800 for the rough-in.

The permit and inspection sequence in Cicero runs as follows: (1) Homeowner or contractor submits a completed permit application (City of Cicero Building Department form) along with floor plans showing finished layout, egress windows, mechanical systems, electrical load, and moisture-mitigation strategy. If there's a history of water, include the engineer's moisture report. (2) Plan-review phase (3–4 weeks): Cicero's plan examiner checks code compliance, dimensional accuracy, and consistency with any recorded liens or HOA restrictions. (3) Permit issuance: once approved, you pay the permit fee ($200–$500 typically based on square footage and system count) and receive a permit card. (4) Work begins. (5) Rough-trades inspection (framing, egress windows, plumbing roughin, electrical rough-in, HVAC ducts if applicable): Cicero inspector verifies dimensions, window sill heights, circuit protection, pump installation, and vent routing. (6) Insulation, drywall inspection: Cicero inspector confirms insulation coverage and drywall thickness (1/2-inch minimum in basements per IBC R302.10 for fire rating). (7) Final inspection: city inspector verifies all outlets work, smoke and CO alarms are installed and interconnected, egress window well is properly drained and labeled, and all mechanical systems operate. You cannot legally occupy the space until final inspection passes and the permit is signed off. This entire process takes 4–8 weeks from permit application to move-in, depending on plan-review speed and inspection availability. Cicero's Building Department is generally responsive (inspections can be scheduled within 3–5 business days), but delays happen if you're on a busy summer season or if inspections find defects requiring rework.

Three Cicero basement finishing scenarios

Scenario A
Finished family room with wet bar, no bedroom, no bath — Cicero bungalow, 600 sq ft, ceiling height 7 feet 2 inches
You want to finish your basement as a rec room with a wet bar (sink + drain, no toilet). The ceiling height is 7 feet 2 inches — well above the 7-foot minimum. Because there is no bedroom and no toilet, you do NOT need an egress window per IRC R310 (egress is required only for sleeping rooms and means of egress from habitable spaces, not for family rooms or bars). However, you still need a building permit because you are creating a habitable space with finishes (drywall, flooring, insulation). You also need an electrical permit for the wet-bar circuits and any recessed lights; if the wet bar has a sink within 6 feet, that outlet must have GFCI. You need a plumbing permit for the sink trap and drain — the drain will likely tie into an existing basement rough drain or will need to slope toward a sump pit. Since there is no toilet, you do not need an ejector pump (assuming the drain is above the main line or slopes to an existing sump). Moisture mitigation is still required: the city will ask to see evidence of perimeter drain or sump-pump activity before issuing the permit. If the basement has any history of water, you will need an engineer's moisture report. The permit fee is approximately $250–$350 (typically 1.5–2% of the project valuation, or a flat rate for finishing without plumbing add-ons). Plan review takes 3–4 weeks. Inspections: framing + egress windows (none required here, so no window inspection), electrical rough-in, plumbing rough-in, insulation, drywall, final. Timeline: 5–7 weeks from application to final. The wet bar itself (countertop, cabinets, beer fridge) does not require additional permits — those are finish items.
Building permit required | Electrical permit required (wet bar circuits, GFCI) | Plumbing permit required (sink, drain, no ejector pump) | No egress window required (no bedroom) | Moisture mitigation plan required | Total project cost estimate: $8,000–$15,000 (finishes, framing, MEP rough-in) | Permit fees: $250–$350 total
Scenario B
Basement bedroom plus half bath with toilet — Cicero ranch, 400 sq ft, ceiling height 6 feet 10 inches, existing window well present, no documented water issues
You want to add a bedroom and a half bath (toilet + sink, no shower) to a basement. The ceiling height is 6 feet 10 inches, which meets the 7-foot minimum (just barely). There is an existing window well with a basement window. This is a complex permit because of the egress and plumbing requirements. First, the egress window: you must verify that the existing window is at least 5.7 square feet of net opening (measure the actual pane opening, not the frame) and that the sill is no more than 44 inches above the finished floor. If the window is smaller or the sill is higher, you must enlarge it or install a new egress window. The existing window well must be inspected: is there standing water, algae, or poor drainage? If so, the well must be cleaned, a floor drain installed, and the walls waterproofed. Cicero's inspector will require photographic evidence of the window well condition and a signed statement that it meets code before the permit is finalized. Cost to retrofit an existing window well with drain and waterproofing: $800–$1,500. If the window is undersized or the sill is too high, you are looking at a new egress window, which runs $2,500–$4,500 installed. Second, the plumbing: a toilet below the main sewer line (which is typical in Cicero basements) requires an ejector pump, sump pit, discharge line, and vent. The plumber will need to cut the slab, install the sump, and run PVC to daylight. Cost: $2,000–$3,500. A radon-mitigation stack must also be roughed in (passive system, 3-4 inch PVC from under slab through roof): $400–$800. Building permit fee: $300–$450. Electrical permit: $100–$150 (bedroom outlets, bathroom circuits with AFCI/GFCI). Plumbing permit: $150–$250. Total permit fees: $550–$850. Plan review includes verification of egress window location, bedroom square footage, ceiling height, and ejector-pump discharge routing; this can take 4–5 weeks if the building examiner finds the egress window undersized or the sump-discharge vent routed incorrectly. Inspections: framing (egress window sill measured and labeled), plumbing rough-in (ejector pump installed and tested, discharge line slope verified, radon vent stack present), electrical rough-in (AFCI/GFCI circuits identified), insulation, drywall, final. Timeline: 6–10 weeks depending on whether you need to retrofit the egress window or cut the slab for the ejector pit. This is Cicero's most common basement-finishing scenario, and the permitting process is well-trodden: the city knows what to look for, inspectors are experienced, but delays happen if egress or plumbing issues require rework.
Building permit required | Electrical permit required (AFCI in bedroom, GFCI in bath) | Plumbing permit required (toilet, ejector pump, radon stack) | Egress window retrofit or new egress window ($800–$4,500 depending on existing window) | Moisture mitigation plan required (even without documented water issues, due to toilet/sump) | Ejector pump and discharge system ($2,000–$3,500) | Total permit fees: $550–$850 | Total project cost estimate: $15,000–$25,000
Scenario C
Basement storage/utility room with new flooring and paint, no fixtures, no egress window — Cicero bungalow, 800 sq ft, ceiling height 6 feet 6 inches
You want to clean up and finish an unfinished basement as a storage area and utility space (furnace, water heater, washer/dryer installed by utilities, no modifications). You install vinyl plank flooring directly over the existing concrete slab, paint the walls, and hang shelving. You do not add any new electrical circuits, plumbing fixtures, bedrooms, or egress windows. In this case, you may NOT need a permit — finishing a basement for storage or utility space without adding habitable spaces or fixture modifications is often exempt under IBC R101.2 (maintenance and alterations). However, Cicero's Building Department is stricter than some Cook County suburbs on this exemption: even if you are exempting the storage finishing itself, the city will STRONGLY RECOMMEND a moisture inspection and remediation if the basement has any history of dampness or water intrusion. This is not a permit requirement, but if you later claim you did not know about moisture issues, Cicero's Building Department will use that against you if a neighbor complains or if you try to sell the home. The flooring itself is exempt — vinyl plank or concrete sealer does not require a permit. However, if you want to add a floor drain or sump-pump pit for future wet-basement management, that is a plumbing permit (even if no toilet is present). If you add new electrical outlets to support a future washer/dryer or to light the space, and those outlets are not part of your original home's circuits, they require an electrical permit. If you simply want to plug a washer/dryer into an existing outlet that your home already has, no permit is needed. The safest approach: do a moisture-intrusion inspection (hire a Cicero-licensed home inspector or a structural engineer, $400–$800) to document the basement's drainage condition, get a written report, and share it with Cicero's Building Department informally (no permit required). If the report shows problems (standing water, efflorescence, mold), remediate proactively (install interior or exterior perimeter drain, seal cracks, install a sump pump) — this then requires a plumbing permit. If the report shows the basement is dry, you can proceed with storage finishing confidence. This scenario illustrates Cicero's unique enforcement posture: the city prioritizes moisture mitigation over mere permit count, so even if you're not adding a bedroom or bath, the city wants to know that you've addressed water risk. This approach is stricter than some suburbs (Forest Park or Berwyn) that let homeowners finish storage basements with zero documentation. Timeline: if no permit is needed, work can start immediately after moisture inspection (1–2 weeks). Total cost: $5,000–$8,000 (flooring, paint, shelving, moisture inspection, maybe perimeter drain if needed).
No permit required for storage/utility finishing | Moisture-intrusion inspection recommended ($400–$800, not a permit but due diligence) | Electrical permit only if adding new circuits ($100–$150 if required) | Plumbing permit only if adding sump or drain ($150–$250 if required) | Total project cost estimate: $5,000–$8,000 (including proactive moisture remediation if needed) | Permit fees: $0 if moisture is already dry; $250–$400 if perimeter drain or sump needed

Egress Windows: The Single Largest Code Challenge in Cicero Basements

IRC R310.1 states that every basement bedroom (and every bedroom, period) must have an emergency escape and rescue opening that is directly to outdoors or to a public way, with a minimum net clear opening of 5.7 square feet, a minimum height of 24 inches, a minimum width of 20 inches, and a sill height no more than 44 inches above the finished floor. For basement windows, this means the window well (if present) and the window itself must be measured and verified to code. Cicero's Building Department requires this egress window to be identified on the permit plan with a label and dimensions, and the inspector must physically verify the window and sill height during framing inspection (before drywall is installed, because drywall covers the window well and sill). If the window does not meet code, the inspector will red-tag the permit and order the window to be enlarged or replaced. This is non-negotiable.

Many Cicero basements built before 1980 have small, fixed basement windows (3 feet wide × 2 feet tall) that do not open and do not meet the 5.7 square foot net opening requirement. These windows are useless for egress. You have three options: (1) replace the existing window with a larger, operable egress window (4 feet wide × 4 feet tall, minimum), which requires cutting a larger opening in the basement wall, installing a new window frame, and upgrading the window well; cost: $2,500–$4,500. (2) Install a supplementary emergency egress door, such as an exterior bulkhead stairwell with a door leading to grade; cost: $4,000–$8,000. (3) Do not finish the basement as a bedroom — finish it as a rec room, family room, storage, or utility space instead, and skip the egress window requirement entirely. Option 3 is often the cheapest and most practical for homeowners with poor basement window situations.

Cicero's window-well inspection is stringent. The inspector will check for standing water, algae growth, rust on the well grate, and slope of the well floor. If water is present or the well is clogged, the inspector will require cleaning and drainage installation before approving the egress window. This can delay your project by 1–2 weeks if the well requires excavation and a perimeter drain. The well must also have a clear path from the window to the outdoors; if landscaping, AC units, or garden walls block the opening, those must be moved or removed. Cicero inspectors have seen homeowners dig out a beautiful egress window only to block it with a downspout or a deck, negating the whole point. The code requirement is that the opening must provide a clear, unobstructed means of escape in a fire — this is a safety rule, not a bureaucratic box-check.

Moisture Mitigation and the 42-Inch Frost Depth: Why Cicero's Building Department Requires a Dry Basement Plan

Cicero sits in Cook County's glacial-till zone, characterized by dense clay and silt soils with 42-inch frost depth (compared to 36–48 inches elsewhere in Illinois). This soil type drains poorly; water from snowmelt and heavy rain percolates slowly through the clay and backs up against foundation walls. The city's aging storm-sewer infrastructure (most combined sewers built 1920–1960) exacerbates the problem: basement backups during heavy rain are common in Cicero. Additionally, many Cicero basements have no perimeter drain or only a partial perimeter drain installed decades ago. Cicero's Building Department has learned (through decades of permit disputes and insurance claims) that finishing a basement in this environment without addressing moisture is a disaster waiting to happen. A finished drywall, flooring, and fixtures soaked by a foundation leak become mold, structural damage, and a worthless space within months. To prevent this, Cicero's Building Department now requires that any basement finishing (habitable or not) must be accompanied by evidence of moisture mitigation: either proof of an existing sump pump in operation, an interior or exterior perimeter drain installed within the past 10 years, or a vapor-barrier retrofit (6-mil polyethylene taped at seams and sealed at the perimeter) if the basement is dry but at-risk.

If your Cicero basement has ANY history of water intrusion (past flooding, seepage, efflorescence, mold), the Building Department will demand a licensed engineer's moisture-mitigation report before issuing the finishing permit. This report must specify the problem (standing water, hydrostatic pressure, capillary rise, surface water), the proposed solution (new perimeter drain, interior drain system, sump pump upgrade, exterior grading changes, sump-pump discharge to grade), and a timeline for implementation. The report typically costs $1,500–$3,000 and adds 2–4 weeks to the permit-review timeline while the engineer conducts a site visit, pulls moisture meters, and writes recommendations. Once the report is submitted, Cicero's plan examiner will review it and may require that the drain system be installed and inspected BEFORE the finishing permit is issued (not after). This is Cicero-specific: many suburbs allow the finishing permit to be issued with a condition that moisture remediation be completed, but Cicero often requires proof of existing or completed drainage before moving forward. This approach protects homeowners from finishing a basement that then gets soaked, but it also adds significant cost and delay to projects in moisture-prone homes.

The practical takeaway: if you're finishing a basement in Cicero and your basement has ever shown signs of water, budget $4,000–$8,000 for perimeter drain or sump-pump upgrade, plus $2,000–$3,000 for the engineer's report and plan review, before you even pour a foundation for new finishes. If your basement is already dry with an existing sump pump or drain, you're in better shape — provide the Building Department with photos and maintenance records of the sump pump, and the permit will move faster. The frost depth also affects any new structural work in the basement: if you're adding a new wall or footer, it must be below the 42-inch frost line. This is rarely an issue for simple finishing (drywall and flooring do not require below-grade footers), but if you are moving a wall or adding a structural element, the frost depth matters.

Common questions

Can I finish my basement as a bedroom without an egress window if I add a second stairwell?

No. IRC R310.1 requires an emergency escape and rescue opening (egress window or exterior door) from every basement bedroom, in addition to any required interior stairs. A second stairwell is a code-required second exit, but it does not satisfy the egress window requirement. The window must be operable and directly accessible to outdoors, with a minimum sill height of 44 inches or less. Cicero's Building Department will not approve a bedroom permit without this window.

My basement has a 6-foot 8-inch ceiling. Can I still finish a bedroom?

No. IRC R305.1 requires a minimum ceiling height of 7 feet in any habitable space. 6 feet 8 inches is below code. You are limited to storage or utility spaces. The 7-foot rule is measured from the finished floor to the lowest point of the ceiling (including beams, ducts, or joists). Cicero's inspector will measure during framing inspection and will not approve drywall in a bedroom that does not meet this height.

Does Cicero require a radon-mitigation system in a finished basement?

Illinois state code requires radon-mitigation-ready design in any new or substantially renovated basement space. This means a 3-inch or 4-inch PVC vent stack must be roughed in from under the slab and extended through the roof (or capped above the roof for future connection). The system does not need to be activated or powered unless radon testing detects high levels. Cicero's Building Department will verify this stack is present during rough framing inspection. Cost is $300–$800 for the rough-in.

If I'm just painting and finishing flooring in an unfinished basement, do I need a permit?

If you are finishing the basement for storage or utility space (no bedrooms, no bathrooms, no new fixtures), you likely do not need a permit. However, Cicero's Building Department strongly recommends a moisture-intrusion inspection to document the basement's dry condition, especially if you plan to sell the home or if there is any history of water. A moisture inspection is not a permit but is insurance against future problems. If your basement is damp, you will need to address moisture before finishing, which may require a plumbing permit for sump or drain installation.

What is the most common reason basements finish in Cicero fail inspection?

Egress window issues are the top reason. Homeowners underestimate the window size or sill-height requirement, or they discover that their existing window is too small and must be replaced, adding $2,500–$4,500 to the project. The second most common issue is inadequate moisture mitigation: the inspector discovers standing water or seepage that was not addressed, and the permit is red-tagged until the homeowner hires a drain contractor. Plan ahead for these costs.

Can an owner-builder (me, the homeowner) pull a basement-finishing permit in Cicero, or do I need a contractor?

Yes, owner-builders can pull permits in Cicero for owner-occupied homes under Illinois law. You must own and occupy the home as your primary residence. You will still need to hire licensed electricians and plumbers for those trades (you cannot self-perform electrical or plumbing in most cases), but the building permit and general contracting can be owner-pulled. This saves the general contractor markup (typically 15–25%) but requires you to manage inspections and code compliance.

How long does a basement-finishing permit take from application to final inspection in Cicero?

Typically 6–10 weeks if the project is straightforward (no egress window replacement, no moisture remediation required). Plan review takes 3–4 weeks. Inspections (framing, electrical rough-in, plumbing rough-in, insulation, drywall, final) take 2–3 weeks depending on inspector availability and whether rework is needed. If you need to replace an egress window or install a perimeter drain, add 2–4 weeks. Weather delays (winter concrete work, summer backlog) can add another 2–3 weeks.

What is the typical cost of adding an egress window in a Cicero basement?

Retrofitting an existing basement window with a larger, operable window and upgraded well: $2,500–$4,500. This includes cutting a larger opening in the wall, installing a new window frame, sealing and waterproofing the well, installing a floor drain, and removing/relocating any landscaping or exterior obstacles. If you must install a supplementary exterior egress door (bulkhead stairwell), expect $4,000–$8,000.

Do I need a permit if I am adding a basement bathroom without a toilet (just a sink and shower)?

Yes. Any new plumbing fixture in a basement (sink, shower, or toilet) requires a plumbing permit. If you add a shower or sink that drains below the main sewer line (typical in Cicero basements), you will need a sump pump and ejector system (cost: $2,000–$3,500). If the drain is above the main line (rare), you may only need a trap and vent. You will also need a building permit for the space and an electrical permit for the bathroom circuits (GFCI for outlets within 6 feet of water sources).

What if I discover mold or water damage during basement finishing in Cicero? Do I need to stop work and notify the city?

Yes. If you discover mold, active water intrusion, or structural damage during framing or rough-in, you must stop work and notify Cicero's Building Department immediately. The inspector will require that the problem be remediated (mold removal, structural repair, drainage system installation) before work can resume. Depending on the severity, you may need a third-party inspection or engineer's report. This is a code-compliance issue and a safety issue, and Cicero takes it seriously.
