Downey Zoning Restrictions Rules (2026): What You Need to Know

Downey's zoning code under Article IX, Chapter 3 permits home-based businesses in residential zones subject to a Home Occupation Permit issued by the Planning Division. The home occupation must be clearly incidental and secondary to the primary residential use of the dwelling and must not change the residential character of the property.

Key restrictions include: the business must be conducted entirely within the enclosed living area of the home and may not use garages, accessory structures, or outdoor areas for business purposes. No exterior signage, displays, or advertising visible from the public right-of-way is permitted. Client, customer, and patient visits to the home are prohibited. No employees other than residents of the dwelling may work on the premises. The business may not generate noise, vibration, odors, fumes, glare, or electrical interference detectable from outside the dwelling. No commercial vehicles, equipment, or materials may be stored on the property beyond what is typical for residential use. Delivery and shipping activity must be limited to what is normal for a residential address. The business may not occupy more than 25% of the total floor area of the dwelling. A valid City business license is also required in addition to the Home Occupation Permit.
