Stanislaus County, CA Home Business: Zoning Restrictions (2026)

Stanislaus County permits home occupations as an accessory use in its agricultural and residential zoning districts, with the regulations consolidated in Title 21, Chapter 21.94 of the Zoning Ordinance (administered by the Department of Planning and Community Development). The stated intent (Section 21.94.020) is to reduce the impact of the home occupation so that its effects on the neighborhood are undetectable from normal and usual residential activity. Key zoning limits include: only occupants of the dwelling may be engaged in the home occupation on the property (in a partnership or corporation at least one member must be a resident), though off-site employees or partners are allowed so long as they do not work or report for work at the property. The use must be clearly incidental and subordinate to residential use and may occupy no more than 20 percent of the habitable floor area of the principal dwelling. No mechanical equipment may create noise, dust, odor or vibration detectable at the property line, and noise at the property line may not exceed 65 dBA. There may be no outdoor storage of materials or supplies, no outdoor display of products, and the use may not generate more traffic than is normal for a residential district or require parking of more than two additional vehicles. Certain specific uses (beauty/barber shops, contractor offices, furniture repair, and limited trucking in the A-2 district) are allowed subject to extra limitations.
