Pierce County, WA Home Business: Signage Rules (2026)

110(A)(1)(g) is one line inside the General Standards that apply to every home occupation and cottage industry in unincorporated Pierce County: Signage is regulated by Title 18B PCC, Development Regulations, Signs. That cross-reference matters because a home business doesn't get its own signage allowance the way it gets its own parking formula or customer-hours rule; instead its sign is judged under the same permitting scheme that governs every commercial sign in the county. 030(A) requires a sign permit from the Planning and Public Works Department (PPW) before any sign is installed, constructed, or altered, and that permit is approved only when the sign advertises or announces a legally established use, meaning the home occupation itself has to already be a lawful use before a sign for it can be permitted.

030(B)(2)(a) carves out the exemption that covers most home-business identification signs in practice: a sign not exceeding 2 square feet in area that is stationary and non-illuminated needs no permit at all. 030(C) requires a site plan, drawings or photographs of the sign, and its dimensions and materials for multi-tenant or non-like-for-like requests. 030(D) still requires every sign authorized under Title 18B PCC, including a home occupation's, to meet the International Building Code or other adopted building code for structural safety.
