Why Build an ADU in Loomis?

Loomis's large lots and rural character make it ideal for spacious, private detached ADUs that feel like separate homes. The town's location between Sacramento and the foothills attracts a diverse tenant base: remote workers seeking space, families needing multigenerational housing, and professionals commuting to Rocklin and Roseville. Estimated rental income of $1,400–$2,200/month on a $190,000–$330,000 construction cost delivers strong returns, particularly for premium detached units with private yards. Many Loomis properties have existing agricultural structures — barns, workshops, storage buildings — that may qualify for conversion to ADUs at significantly lower cost than new construction. The town's equestrian character and large lots also mean ADUs can be positioned for maximum privacy, a key selling point for premium rental tenants.

Loomis ADU Regulations & Permits

Key rules and requirements for building an ADU in Loomis, Placer County.

Loomis is an incorporated town — permits are processed through the Town of Loomis Community Development Department at 6140 Horseshoe Bar Road, Loomis, CA 95650. Phone: (916) 652-1840.

Local Tips for Loomis ADU Projects

Many Loomis properties use septic systems — factor in a septic evaluation ($500–$1,500) and potential expansion ($8,000–$25,000) before finalizing your ADU budget. Contact Placer County Environmental Health at (530) 745-2300.

Well water properties may need a well yield test to confirm adequate water supply for the ADU. Budget $500–$1,500 for the test and 6–12 weeks if well work is needed.

Large lots mean more flexibility in ADU placement, but also more site preparation work. Get a topographic survey and soil report early — Loomis's clay soils can complicate foundations.

Existing agricultural structures like barns or workshops may qualify for conversion to ADUs under AB 2221 (2023). This can reduce construction costs by 30–50% compared to new construction.

Schedule a pre-application meeting with the Town of Loomis Community Development Department before hiring a designer. They can identify site-specific constraints and save you costly redesigns later.
