Building without a permit in Kentucky

By Mario Bailey Last checked · 4 official sources

Quick answer

Anyone who violates the Uniform State Building Code or the Uniform State Residential Code, or any order issued under them, faces a fine of $10 to $1,000, and each day the violation continues is a separate offense. For a single-family home, though, state law does not itself require a building permit: permits, inspections and certificates of occupancy are mandatory only where the local government has passed an ordinance or set up a building inspection program (KRS 198B.060(1) and (8)).

What Kentucky law says

Anyone who violates the Uniform State Building Code or the Uniform State Residential Code, or any order issued under them, faces a fine of $10 to $1,000, and each day the violation continues is a separate offense. For a single-family home, though, state law does not itself require a building permit: permits, inspections and certificates of occupancy are mandatory only where the local government has passed an ordinance or set up a building inspection program (KRS 198B.060(1) and (8)). Plumbing and electrical permits are a separate, statewide track: KRS 318.134 requires a plumbing installation permit and KRS 318.990 fines violations $10 to $100 or up to 90 days in jail per offense, each day a separate offense, and KRS 227.480 requires a permit before electrical construction, alteration or repair. Separately, every building permit applicant must swear by affidavit that contractors carry workers' compensation and unemployment insurance, and a court can fine a person who fails to comply up to $4,000 or the total of uninsured claims, whichever is greater, enforced by the county attorney (KRS 198B.060(10)).

Can you get a permit after the work is done?

No Kentucky statute sets an after-the-fact or as-built permit procedure, an investigation fee or a fee multiplier for unpermitted work; that is left to local ordinance. The state's enforcement tool is the injunction: the department or a local enforcing agency can go to court to stop the sale, use, occupancy or construction of a building that does not conform to the code. For electrical work the state regulation is explicit: an inspector who learns that permit-requiring electrical work was done without a permit shall inspect it (815 KAR 35:020, Section 3(3)), and work covered before inspection must be uncovered unless unnecessary (Section 3(6)).

Cited from KRS 198B.120; 815 KAR 35:020, Section 3(3), (6): official text.

The typical path, whatever your locality calls it: stop any ongoing work, contact the permit office before they contact you, apply for the permit describing what was actually built, and expect the office to require opening up or inspecting concealed work. Voluntarily coming forward generally goes better than waiting for a complaint or a sale to surface it.

What Kentucky permit offices charge when work starts first

The statute above sets the ceiling; the bill comes from the local office. 2 Kentucky jurisdictions we cover publish a specific surcharge for work started before the permit, quoted here from the fee schedule or permit page we verified, each linked to the page that carries the citation.

Jurisdictions not listed either publish no surcharge clause or publish one we could not quote from an official schedule; their permit pages state what we could verify.

Who can pull the permit

Kentucky has no state general or residential contractor license, so no state license stands between a homeowner and building their own house; whether a building permit is needed at all for a single-family home depends on local ordinance (KRS 198B.060(1)). The licensed trades each carry a homeowner exemption. A homeowner may get a state plumbing permit for their own home if they apply before starting, file an affidavit, personally do all the work, and have not taken another homeowner permit for a new home in the last five years. The electrical licensing law does not stop a homeowner or farmer from wiring their own property (KRS 227A.030(3)), and an electrical permit may issue to them without proof of a contractor license (KRS 227.480(2)(a)); the HVAC licensing law does not apply to an owner working on property they own and occupy (KRS 198B.674(3)).

Was a permit needed in the first place?

Not every project needs one. Across the 2 Kentucky jurisdictions we have verified, 1 answered rules need no permit at all and 10 turn on a size or scope condition the jurisdiction publishes. If the work falls under one of those, the question changes from penalties to paperwork.
