What happens if I build without a permit?
If work required a permit, contact the responsible local authority before continuing. The enforcement and after-the-fact process is local and can depend on the scope, safety issues, and what can be documented or inspected.
What to do first
If work required a permit, contact the responsible local authority before continuing. The enforcement and after-the-fact process is local and can depend on the scope, safety issues, and what can be documented or inspected.
Printable checklist
- Stop covering or concealing work that may need inspection.
- Document the current condition with plans, photos, receipts, and contractor records.
- Identify the authority responsible for the property and project type.
- Describe the work accurately and ask for the local after-the-fact path.
- Expect that parts of the work may need to be exposed, corrected, engineered, or inspected.
- Keep every approval and closeout record once the issue is resolved.
How this works in practice
If a project required a permit and work has already started, do not assume the path is the same everywhere. Local building and code-enforcement authorities set their own inspection, documentation, and enforcement processes.
The practical first step is to contact the responsible authority, describe the work accurately, and ask what it needs to evaluate the project. It may require an application, plans, contractor or engineering records, and inspections. Work that is covered or incomplete can be harder to evaluate than work that remains visible.
Do not conceal the work or make further changes based on a national rule of thumb. Requirements for permits, inspections, corrections, fees, records, contractors, and disclosure are jurisdiction- and transaction-specific. If a sale, insurance question, or legal dispute is involved, get advice from the responsible authority and a qualified local professional.
For future work, verify the permit path before construction starts and keep the issued permit, approved plans, inspection results, and closeout records with the property documents.
What an application can look like
These examples show how a project scope typically turns into an application packet. The issuing authority decides the exact forms, documents, and reviews for a property.
Interior remodel
Kitchen or first-floor remodel that moves walls and changes electrical or plumbing.
Remodel the first-floor kitchen; remove one partition wall, install a sized replacement beam where required, relocate the sink, add receptacles and lighting, and replace finishes without changing the building footprint.
Typical application material
- Existing and proposed floor plans
- Demolition and framing notes
- Electrical, plumbing, and mechanical scope
- Structural detail when a load-bearing wall changes
Likely review touchpoints
- Building review for structural and life-safety changes
- Separate or combined trade permits depending on the jurisdiction
- Rough-in and final inspections before work is concealed or occupied
Residential deck
A new elevated rear-yard deck attached to an existing home.
Construct a 12 ft × 16 ft attached rear deck, approximately 30 in above grade, with pressure-treated framing, code-compliant guards and stairs, and concrete footings below the locally required depth.
Typical application material
- Permit application describing size, height, materials, and attachment
- Dimensioned site plan showing lot lines, house, deck, and setbacks
- Framing, footing, guard, stair, and ledger details
- Contractor or owner-builder information where the authority requires it
Likely review touchpoints
- Zoning placement and lot coverage
- Structural and building-code review
- Footing, framing, and final inspections
EV charger / electrical work
A hard-wired Level 2 charger on a new dedicated circuit.
Install one 48A hard-wired Level 2 EVSE on a dedicated 60A, 240V branch circuit from the existing 200A service panel; route conductors through the attached garage and mount EVSE on the interior wall.
Typical application material
- Electrical permit application and equipment specifications
- Circuit size, conductor, breaker, and EVSE rating
- Panel schedule or load calculation when required
- Service-upgrade information if existing capacity is insufficient
Likely review touchpoints
- Electrical-code review
- Utility coordination if the service or meter must change
- Electrical inspection before final energization where required
Active City of Chicago permits currently in the GovCodex Illinois permit corpus.
Loaded permits with a recorded work description.
Recorded structural-repair permits in the loaded Chicago corpus; median recorded fee $500.
Loaded records run from Jan. 3, 2006 through July 24, 2026.
Snapshot checked September 28, 2026. GovCodex Illinois permit data currently reflects 842,269 active City of Chicago permit records loaded from the City of Chicago dataset, with issue dates from January 3, 2006 through July 24, 2026. Historical counts, elapsed time, and recorded fees describe observed permits only. They do not determine whether a permit is required, predict approval, or replace the issuing authority’s current rules and fee schedule.
What else to know
What the authority needs to establish
The central questions are usually whether the work required approval, whether it can be inspected in its current condition, and whether it complies with the applicable rules. The answer can depend on when the work was done and what documentation survives.
Property transactions raise the stakes
Unresolved permit history can surface during a sale, refinance, insurance review, appraisal, or later renovation. A clean record should show what was approved, which inspections passed, and whether the permit was closed.
Check the actual project against the actual property.
Start with the address and scope. GovCodex will identify the relevant authority, requirements, and permit path for the project.
