Claremont is one of the strongest ADU markets we serve, and one of the most rewarding to build in. With the seven Claremont Colleges, the rental demand for a well-built backyard home is consistent and premium. We have completed multiple ADUs across Claremont — more than in almost any other city — and homeowners here repeatedly tell us they felt supported through every step, including the city’s more design-conscious review.
“The City of Trees” takes its character seriously, from the historic Village to the tree-lined streets north of Foothill. That means thoughtful placement, mature-landscape protection, and plans that fit the neighborhood rather than fight it. Our architects design to that context so your ADU adds value without friction.
Just three miles from our Upland office, Claremont projects get fast site visits and close attention from start to finish.

ADU rules & permits in Claremont
Reviewed by the City of Claremont Community Development Department
Backyard Estates handles the entire permitting process for you. Here’s what California’s statewide ADU law means for your Claremont property:
- California law requires cities to approve a complete ADU application ministerially (no public hearing) within 60 days.
- Detached ADUs up to 800 sq ft with 4-foot side and rear setbacks must be allowed by right, and most lots qualify for an ADU up to 1,200 sq ft.
- No additional off-street parking can be required when the property is within half a mile of public transit.
- Owner-occupancy cannot be required for ADUs permitted through the end of 2025, making an ADU a true rental-income option.
Specific setbacks, fees, and overlay rules are confirmed for your exact parcel during your Formal Property Analysis.

Good to know
Claremont ADU questions, answered
Claremont takes neighborhood character seriously, but California’s statewide ADU law still applies, and ministerial approval is required for qualifying projects. Backyard Estates has completed many Claremont ADUs and handles the city process for you end to end.
Yes. An ADU is a popular way for Claremont homeowners to earn rental income given the steady demand from the colleges, and current law does not require you to live on-site for ADUs permitted through 2025.
The City of Claremont Community Development Department reviews ADU applications. We prepare the plans and manage submittal and review on your behalf.
