LANDSCAPING x LOUISIANA

Landscaping contractor requirements in Louisiana.

Under R.S. 3:3804, no one may receive fees for, advertise, or solicit work in a regulated horticulture profession without a license (or a licensed employee or supervisor). The Landscape Horticulturist license covers bed preparation, plant and sod installation, pruning, fertilizing, and landscape maintenance; the exam costs $150, the license $125 a year, and every license expires January 31. Irrigation needs a separate Landscape Irrigation Contractor license plus a State Plumbing Board water supply protection specialist endorsement before connecting to a water supply; tree removal needs an Arborist license.

Two more layers: applying pesticides or herbicides for hire by ground requires an LDAF Ground Owner Operator license and certified commercial applicators, and non-residential projects of $50,000 or more also need an LSLBC classification such as Landscaping, Grading, and Beautification. Landscaping is exempt from the LSLBC Home Improvement registration, so residential yard projects do not trigger that band.

LICENSE TRUTH
Louisiana licenses landscapers: planting, sodding, pruning, fertilizing, and landscape maintenance for hire require a Landscape Horticulturist license from the LDAF Horticulture Commission — only mowing, edging, and hand-weeding are exempt.
STATE ↔ LOCAL
Horticulture licensing is state-level (LDAF); parishes and cities collect occupational license taxes and keep their own backflow-device ordinances, which R.S. 3:3816(6) expressly preserves. Arborist regulation is preempted from local ordinance (R.S. 3:3804(E)). For $50,000+ non-residential projects, the LSLBC permit gate applies: 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)).

§ 01 · Permit Stack

How landscaping work is governed in Louisiana.

NOTE
Mowing is the exception, not the rule

LDAF says yard work — cutting lawns, edging, hand-weeding beds — needs no license. Planting, sod, pruning, fertilizing, and maintenance of nursery stock do.

NOTE
One date for everyone

All Horticulture Commission licenses expire January 31 each year.

NOTE
Out of the HI band

Landscaping is expressly exempt from LSLBC Home Improvement registration, so residential landscape jobs never need that $7,500 registration.

§ 08 · Louisiana FAQ

Questions landscaping contractors ask about Louisiana.

Q01Do landscapers need a license in Louisiana?+
Yes. Planting, sod installation, pruning, fertilizing, and landscape maintenance for hire require a Landscape Horticulturist license from the LDAF Horticulture Commission. Lawn mowing, edging, and hand-weeding do not.
Q02Do I need a separate license for sprinklers?+
Yes — a Landscape Irrigation Contractor license, plus a State Plumbing Board water supply protection specialist endorsement before connecting to a public or private water supply.
Q03Do I need an LSLBC contractor license for landscaping?+
Only for non-residential projects of $50,000 or more. Landscaping is exempt from the residential Home Improvement registration.
Q04What happens if I landscape without a license?+
The Horticulture Commission may assess civil penalties of up to $500 per violation for a first offense, $1,000 for a second, and $1,500 after that, plus hearing costs.

Pending verification: Whether R.S. 3:3816(1)'s mowing/edging/hand-weeding exemption (written for work 'under the direction and responsibility of the owner' and not for commercial establishments) covers a mowing business serving commercial properties — LDAF's page describes yard work as unregulated without that qualifier · Liability insurance minimum for the Landscape Horticulturist license itself (only the irrigation contractor minimum was confirmed) · Arborist license fees and exam details (not reviewed) · Local registration or competency-license requirements in Jefferson Parish, Caddo Parish/Shreveport, and Lafayette Consolidated Government were not reviewed on those governments' sites
