What Are ADUs and JADUs?

ADUs, sometimes called granny flats or casitas, are small, self-contained housing units with their own kitchen, bathroom, living space, and separate entrance.
JADUs are smaller units that are typically created from existing space within a home. They include a kitchen and may share a bathroom with the main house.

ADUs and JADUs expand Riverside’s housing options while providing opportunities for multigenerational living, rental housing, and additional homeowner income.

Choose Your ADU Process

There are two routes for developing an ADU, depending on your property, schedule, and design needs.

Both options go through the standard building permit review process. The best path depends on whether you prefer a fully custom design or a more streamlined approach.

Dwell Riverside supports the City’s efforts to expand housing options by providing pre-reviewed, code-compliant ADU plans. The plans offer multiple exterior finishes and flexible layouts that can be adapted to individual site conditions. Pre-review by the Building Division can also help reduce preconstruction architecture and engineering costs.
