Thousand Oaks, CA Home Business: Signage Rules (2026)

TOMC Sec. 2518(a) lists the criteria the Community Development Director checks before issuing a home occupation permit. Subsection (3) bars advertising any commodities or services on the premises, and subsection (4) is the operative sign rule: no signs or structures are permitted beyond those normally allowed in the residential zone, meaning a home-based business gets no special sign allowance just because it operates commercially. That sits alongside the requirement, in subsection (8), that the structure's appearance not be altered and that the operation not be recognizable from the outside as a nonresidential use, and the ban in subsection (7) on outdoor storage of business materials or supplies visible from the street or a neighboring property.

Because these are permit-issuance criteria rather than a standalone sign code, putting up an unauthorized sign is treated as a permit violation: under subsection (b), the Community Development Director can revoke a home occupation permit for violating any condition, and the decision can be appealed to the Planning Commission under Article 28. The permit itself is nontransferable under subsection (c) and cannot be moved to a different address.
