Upland, CA Home Business: Zoning Restrictions (2026)

Home-based businesses in Upland are governed by Chapter 17.27 (Home Occupations) of the Zoning Ordinance, Title 17. The chapter is intended to permit a home occupation as an incidental and accessory use in residential and residential mixed-use zoning districts under conditions that keep the use compatible with the residential character of the neighborhood. Core standards include: the home occupation must be located entirely within the dwelling unit and may not occupy more than 25 percent of the dwelling's gross floor area; there must be no exterior evidence of the business; and it must not generate noise exceeding the limits in Municipal Code Chapter 9.40 (Unnecessary Noise), nor produce dust, odors, vibration, or electrical interference perceptible beyond the property line. The chapter distinguishes minor home occupations (such as professional offices, tutoring, art studios, telephone sales, and domestic services) from major home occupations (such as equipment repair, contractor's offices, light assembly, catering, and food processing), each with different client and employee limits. Any vehicle used in connection with the business is prohibited from parking on the street, and the business may not create traffic or parking demand greater than a strictly residential use, except for permitted client visits. A list of higher-impact uses is expressly prohibited as home occupations.
