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

The Unified Development Code's accessory-use standards for Home-Based Business, UDC § 7.3.O, treat signage as one piece of a broader package of restrictions on running a business out of a house in unincorporated Caddo Parish. Before opening, the operator must obtain a home-based business certificate of occupancy (§ 7.3.O.1), and only a resident of the dwelling may run the business; only residents of that dwelling may be employed in it (§ 7.3.O.2). The sign rule itself is narrow: one identification sign, capped at two square feet, is the only exterior sign, display, or visible activity allowed to hint that the structure is anything but a private residence (§ 7.3.O.3).

All work, including storage, must stay inside the principal building or a permitted accessory structure (§ 7.3.O.4), and no toxic, explosive, flammable, or radioactive materials may be kept on site (§ 7.3.O.5). Client traffic is limited to four visitors at a time, by appointment only, between 7:00 a.m. and 7:00 p.m. (§ 7.3.O.9). Barber and beauty shops face tighter limits still: one operator, one assistant, one styling chair, one shampoo bowl, one appointment at a time, and a special exception from the Zoning Board of Appeals (§ 7.3.O.10). Vehicle and heavy-equipment repair, and storage of tractor-trailers or construction equipment, are barred outright as home occupations (§ 7.3.O.12-.13).
