Building without a permit in Louisiana

By Mario Bailey Last checked · 3 official sources

Quick answer

Louisiana sets no statewide fine or jail term for building without a permit. The Louisiana State Uniform Construction Code adopts the international codes but expressly omits their administrative parts, and those are the chapters that create the permit requirement, so both the duty to pull a permit and the money penalty for skipping it come from parish or municipal ordinance.

What Louisiana law says

Louisiana sets no statewide fine or jail term for building without a permit. The Louisiana State Uniform Construction Code adopts the international codes but expressly omits their administrative parts, and those are the chapters that create the permit requirement, so both the duty to pull a permit and the money penalty for skipping it come from parish or municipal ordinance. R.S. 40:1730.31 is the only enforcement section in the entire Part: the local building official may enjoin further construction as provided by local ordinance, and the municipal, district or parish attorney, the attorney general, or other appropriate authorities may apply for injunctive relief, mandamus or other proceedings in the district court of the parish where the violation occurred. For an ordinary Louisiana town or village governed by the Lawrason Act, the ordinance behind that enforcement is capped at a fine of $500 or 60 days in jail, or both, under R.S. 33:362(A)(2)(b), which reaches every municipality except those under a special legislative charter or a home rule charter, so New Orleans, Baton Rouge, Shreveport and Lafayette sit outside the cap. The hardest statewide penalty in Louisiana attaches to the contractor rather than to the permit: doing work that requires a contractor licence without holding one is a misdemeanor punishable by a fine of up to $500 per day of violation, three months in prison, or both, and a local building department is forbidden to issue a building permit to any person who does not hold an active licence in the right classification.

Can you get a permit after the work is done?

No Louisiana statute creates an after-the-fact or retroactive permit, and none sets an investigation fee or a fee multiplier for unpermitted work. That is a verified negative rather than a gap in the research: every section of the State Uniform Construction Code Part, R.S. 40:1730.21 through 40:1730.40, was read, and none addresses legalizing completed work. Because the state code leaves out the administrative chapters of the model codes and expressly withholds IRC Appendix J, the existing buildings and structures appendix, for local option only, any as-built permit path in Louisiana is a parish or municipal creation, and R.S. 40:1730.32 confirms that fees are a local matter by saying nothing in the Part stops a parish or municipality from imposing the fees needed to implement it. The one statewide rule that does touch already-built work is R.S. 40:1730.33: when an inspector inspects an existing residential structure in order to allow occupancy or reconnect utilities, he must apply the code that was in effect for that locality on the date the original building permit issued. Where no permit record exists, the statute sets an ordered fallback: the date the original permit application was submitted, then a date the building official reconstructs from court records, property transfer records, mortgage, tax or rent records, and finally, if ambiguity remains, the least restrictive code in force during the window running one year before to one year after the earliest recorded transfer of the property.

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.

Who can pull the permit

Yes. R.S. 37:2157(A)(13) exempts an owner who supervises or takes charge of construction, alteration or repair of his own personal residence from the contractor licensing law, but caps the exemption at one residence per year, with the year running from the date the certificate of occupancy issues; the cap lifts only where a change in the owner's legal marital status, or a change in employment forcing a move more than 50 miles from his residence, requires a second home. A separate exemption at R.S. 37:2157(A)(2) covers an owner who takes charge of work on his own property for his own use, where the result will not be for sale or rent and the owner controls access. A residential property owner who physically performs home improvement work on his own residence is also exempt from home improvement licensure under R.S. 37:2157(A)(15)(a). The exemption is not self-executing at the permit counter: R.S. 37:2157(A)(13) requires an affidavit of exemption on a board form in order to obtain the building permit, and R.S. 37:2160(C) obliges the local permit official to collect that affidavit before the permit issues. R.S. 37:2157(B) adds that none of these exemptions waives local or state health and life safety code requirements, so an exempt homeowner still owes the permit and the inspections.
