Jefferson Parish, LA Home Business: Signage Rules (2026)

Sec. 3 sets the standards every home occupation must meet in any dwelling unit in Jefferson Parish, and subsection (j) is the sign rule: no exterior indication of the occupation is allowed except one non-illuminated sign or nameplate, capped at 2 square feet, mounted flush against the wall of the dwelling unit itself. That rules out freestanding yard signs, window displays, awning signs, or anything illuminated, even though those sign types are allowed for standalone commercial buildings elsewhere in the parish's zoning code. The sign standard sits alongside the rest of Sec.

3's home occupation package: only residents of the home can work in the business, the occupation is capped at 15 percent of the dwelling's gross floor area, activity has to stay inside the residence, and no dust, odor, noise, vibration, or electrical interference can be perceptible past the property line. A home occupation also cannot use mechanical equipment beyond what a household normally has, and deliveries have to happen during normal residential hours without blocking traffic. The list of home occupations the parish authorizes under Sec.

4 includes accounting, legal, and consulting services, tailoring, real estate, and specific client-facing services like hair care or tutoring, each still bound by the same 2-square-foot sign cap regardless of the specific occupation.
