Vacaville, CA Home Business: Zoning Restrictions (2026)

VMC 14.09.270 governs Standards For Specific Uses and Activities, including home occupations. The standards apply to any residential unit in Vacaville regardless of zoning designation, and to agricultural districts. Family day-care homes are excluded - they are regulated separately by California Health & Safety Code 1597.30 et seq. and California Government Code 65852.2 (now Gov. Code 66310) which preempts local family-day-care prohibitions for small (up to 8 children) and large (up to 14 children) family day-care homes. Key Vacaville home-occupation standards: (1) the business must be conducted entirely within the dwelling, with no outdoor storage of equipment, supplies, or vehicles related to the business; (2) no more than 20% of the dwelling floor area may be dedicated to the home occupation; (3) only members of the household residing in the dwelling may engage in the business activity - no outside employees coming to the residence; (4) no client/customer visits for the procurement of goods or services; (5) only occasional postal/parcel deliveries by standard residential carriers; (6) no signs visible from outside the dwelling; (7) no display of stock-in-trade in any window; (8) no noise, vibration, smoke, dust, odors, heat, glare, or interference with radio/TV/wifi reception detectable beyond the dwelling. AB 1472 (Gov. Code 1597.30 et seq.) preempts these for state-licensed day care. AB 587 / SB 1100 (Gov. Code 7282.5 limits) frame state-level commercial-cannabis preemption questions. Home occupations must obtain both the Home Occupation Permit (Planning) and the city Business License (Finance Department).
