ConditionalLouisiana State Licensing Board for Contr…
The State Licensing Board for Contractors (LSLBC) regulates three bands at once. Commercial work of $50,000 or more needs a commercial license in the matching major classification (Building Construction for most general contractors). Residential work of $50,000 or more needs the Residential Construction license. Home improvement on an existing residence from $7,500 up to — but not including — $50,000 needs a Home Improvement registration, and the home improvement contractor may not touch structural work (footings, foundations, outside walls, bearing walls, slabs, or roofing systems). Below $7,500 on a residence, the state requires nothing.
The residential line moved recently: Act 178 of 2024 cut it from $75,000 to $50,000 (effective August 1, 2024). Act 757 of 2026 then raised the liability insurance floor for residential, home improvement, and mold licensees from $100,000 to $500,000 effective August 1, 2026, and removed the old rule that let Building Construction licensees skip Home Improvement registration. Project value counts labor, materials, rentals, and all direct and indirect costs — regardless of who pays for the materials.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Louisiana runs on parishes, not counties, and every parish or municipal permit desk is bound by R.S. 37:2160(B): it may not issue a building permit to anyone without an active LSLBC license in the classification that matches the scope, and it must collect a board-form exemption affidavit from owner-builders (§ 2160(C)). LSLBC staff may audit local permit lists monthly (§ 2160(A)). Beyond the state license, a contractor owes only local occupational license taxes, inspection permit fees, and any local competency license for mechanical, plumbing, or electrical contractors (R.S. 37:2156(N), electrical added by Act 757 of 2026); state law preempts local examination authority over LSLBC licensees (§ 2160(D)). In New Orleans, permits run through the Department of Safety & Permits, and a building-permit application must include a copy of the contractor's current Certificate of Registration and license number. Baton Rouge is a consolidated city-parish: the City of Baton Rouge/Parish of East Baton Rouge Permits & Inspections Division handles building, mechanical, plumbing, and electrical permits — except inside the City of St. George, which took over its own permitting on October 16, 2024. Jefferson, Caddo (Shreveport), and Lafayette permit offices apply the same state gate.
The local offices section below names the exact permit desk for every Louisiana county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Act 178 of 2024 cut the residential line to $50,000 and set the home improvement band at $7,500 up to $50,000. Older guides and some LSLBC rule text still say $75,000.
From August 1, 2026, residential, home improvement, and mold licensees must carry $500,000 in liability coverage — certificate sent by the agent, at least six months' term, no exclusions for licensed scopes, LSLBC as certificate holder.
LSLBC offers one-, two-, or three-year renewal terms, but licenses that depend on insurance are not eligible for multi-year renewal.
A practical sequence for a new general contracting contractor in Louisiana. Actual agency processing times are noted in the ledger above.
Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Engaging in contracting without an active LSLBC license is a misdemeanor.
If an unlicensed contractor causes more than $300 in harm or damage, a heavier range applies — imprisonment with or without hard labor.
After notice and hearing, the board may fine up to 10% of the contract or work value, or up to $10,000 where no value applies, plus costs and attorney fees.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.

Pending verification: Current LSLBC fee amounts — the board resets fees each July under LAC 46:XXIX.131; this record uses the statutory caps in R.S. 37:2156(C) · PSI trade-exam vendor fees (paid to PSI; not published on lslbc.gov) · LSLBC rule text (LAC 46:XXIX.301, promulgated November 2023) still describes residential construction and home improvement at $75,000; the statute, as amended by Act 178 of 2024, controls at $50,000 · The LSLBC Aug 1, 2026 compilation still prints the R.S. 37:2157(A)(19) exemption for electrical/mechanical/plumbing licensees, but Act 757 of 2026, Section 2, repeals it — treat it as repealed · Local registration or competency-license requirements in Jefferson Parish, Caddo Parish/Shreveport, and Lafayette Consolidated Government were not reviewed on those governments' sites
