ADU Builder in Perris, CA
Building an ADU in Perris is an excellent way to maximize your property’s potential—whether you’re looking to create additional living space for family, generate passive rental income, or increase your home’s overall value. The City of Perris has established clear and flexible ADU regulations that make the process straightforward for homeowners, while still maintaining neighborhood character. Apex Homes helps simplify every step of the process, from feasibility and design to permitting and construction, so you can build with confidence.
ADU Regulations in Perris
Perris follows California’s state ADU laws while implementing local standards that define what can be built on both single-family and multi-family properties.
- Single-family lots (R-1): One detached or attached ADU + one Junior ADU (JADU). ADUs up to 1,200 sq ft or 75% of the primary dwelling, whichever is less. JADUs capped at 500 sq ft. Side and rear setbacks: 4 ft minimum. Front setbacks are determined by the property’s underlying zoning district.
Height limit: 16 ft or the first-floor ridgeline of the main dwelling, whichever is greater. Exceptions allow ADUs up to 800 sq ft at 16 ft peak on smaller lots. - Multi-family lots (R-2): Up to two detached ADUs permitted, plus conversions of existing non-livable spaces. The same setback and height requirements apply.
Height limits for detached ADUs are flexible—an ADU may not exceed 16 feet above grade or the height of the first-floor ridgeline of the main dwelling, whichever is greater. Unit separation and distance requirements between structures are generally based on the property’s zoning standards; however, the city allows reasonable exceptions to ensure that ADUs up to 800 square feet in size, with a peak height of 16 feet, can still be built even on smaller lots. These balanced regulations give Perris homeowners plenty of flexibility in both design and placement, making it easier to create high-quality, functional living spaces.
