9 rules for unincorporated Jefferson Parish, Louisiana.
Verified from official government sources
Jefferson Parish requires grass and weeds on all property to be kept below eight (8) inches. In June the Parish Council cut the limit from 12 inches to 8. It applies to both occupied and unoccupied lots parishwide.
The Parkways Department controls trees on parish rights-of-way and trims hazardous, dead, diseased or low limbs. If the parish cannot do the work promptly, a property owner may get a permit to hire a qualified company at their own expense.
Jefferson Parish does not require a permit to remove a tree on your own private property. Only trees on the parish right-of-way and public property are protected, and Parkways reserves the right to deny removal of a mature, healthy tree.
Weeds are enforced under the same eight-inch limit as grass. Vacant and abandoned lots are handled by the Weed Control Section, and occupied properties by the Property Maintenance Section, both under Inspection and Code Enforcement.
Jefferson Parish, in wet, riparian-rights south Louisiana, has no standing drought or day-of-week lawn-irrigation restrictions. There is no parish rule limiting when you may water your lawn. Restrictions would only appear during a declared water emergency.
Collecting rainwater is legal in Louisiana and encouraged for outdoor uses. Jefferson Parish sets no permit for residential rain barrels or cisterns. Only commercial systems need a state installation permit; home systems must simply meet applicable plumbing and building codes.
Jefferson Parish does not require native plants or ban ornamental lawns for private homes. Landscaping choices are up to the owner, subject only to the eight-inch height limit and, for new development, the UDC landscape-plan standards.
Jefferson Parish has no ordinance specifically permitting or banning artificial turf on private residential lawns. Front-yard and setback landscaping in new development is governed by the Unified Development Code, but existing homes are not restricted from installing synthetic turf.
Jefferson Parish has no ordinance banning home composting. Residents may compost yard and food waste in a backyard pile or bin, provided it does not create odors, attract rodents or vermin, or otherwise become a public-health nuisance under the parish code.
