If we had to choose again and start the whole process over, we would still choose Backyard Estates.

Permits & fees
Red tape in Corona, handled
Permitting an ADU touches a dozen departments and a stack of fees. We run every one — and it’s already in your fixed, all-in price.
Reviewed by the City of Corona Planning & Development Department
What California’s statewide ADU law means for your Corona 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.
Every city fee — already in your price
No surprise municipal bills. We absorb every Corona permit and city fee into one fixed, all-in price.

Local know-how
Why homeowners build in Corona
Corona is our anchor in Riverside County, and the demand here is strong: growing families who want a safe, independent home on the same property so they can support one another. One Corona family told us that if they had to start the whole process over, they would still choose Backyard Estates — the kind of trust we work to earn on every Riverside County build.
Corona’s newer master-planned communities and its older neighborhoods near downtown call for different approaches, and Riverside County / City of Corona review has its own rhythm. Because we have already built and permitted here, we know how to keep a Corona project moving. Larger lots in areas like Sierra Del Oro and South Corona often support a full detached ADU.
Corona is a straightforward freeway run from Upland, and we manage the distance with clear timelines and steady communication.
