With large lots, high housing demand, and new permit programs, the time is right to build an ADU. ADORE Homes makes the process simple, even if the paperwork feels complex.

We design and build prefab ADUs in Riverside and nearby cities, helping you get from idea to finished space without getting stuck in the system.

ADUs in Riverside County: A Growing Trend

Across the Inland Empire, ADUs are becoming a trusted solution to rising housing costs and space needs. In Riverside, Corona, Moreno Valley, and throughout the county’s unincorporated neighborhoods, homeowners are adding detached units for family, renters, or long-term flexibility.

 

To support this shift, Riverside County introduced free Permit Ready ADU plans. These pre-reviewed plans save time and remove guesswork from the approval process.

 

With more people embracing ADUs, the county is making it easier to build. So are we.

County and City Regulations

Riverside County ADU rules follow state law and allow for both attached and detached units on most residential lots. These rules cover a variety of details, requirements, and benefits.

 

For example:

 

  • ADUs must maintain setbacks of at least four feet from side and rear property lines
  • Attached ADUs cannot be larger than half the main home’s floor area, but detached ADUs may be up to 1,200 square feet
  • Impact fees are waived for ADUs smaller than 750 square feet
  • Homeowners may build one ADU and one JADU (Junior Accessory Dwelling Unit) on a single-family lot

 

Cities within the county, like the City of Riverside, have their own programs with pre-approved plans and faster permit pathways. If you live in a city or suburb with its own rules, we’ll guide you through those, too.

 

At ADORE Homes, we track Riverside ADU regulations for every city and county zone, so you don’t have to figure it out on your own.
