Placer County, CA Home Business: Signage Rules (2026)

Home occupation signage in unincorporated Placer County falls under the home occupation standards of Placer County Code Section 17.56.120, which includes specific sign provisions. The County's Home Occupation Business License Questionnaire (rev. 5/2024) directly asks applicants, 'Will you be placing a sign on the property to advertise the business?', and the answer is reviewed as part of the home occupation approval, since one purpose of the home occupation rules is to keep the residential character of the neighborhood. Because home occupations are intended to be subordinate, incidental uses of a dwelling, on-premises advertising signs are limited in size and number under 17.56.120; applicants should confirm the exact allowance with the Planning Services Division before installing any sign. Outside the home occupation context, on-site advertising signs in the unincorporated county are also subject to the County's general sign regulations and may require a separate sign permit from CDRA. Note we have not independently verified a specific maximum sign dimension for home occupations from the code text, so the precise size limit should be confirmed with Placer County Planning.
