Backyard Estates is based in Upland, and it is the city we know best. Our office sits on West Foothill Boulevard, minutes from the established neighborhoods north of the 210 and the larger lots toward San Antonio Heights. We have walked more Upland backyards than anyone, pulled permits through the Upland Planning Division, and built completed ADUs you can drive past today.

Upland’s mix of generous lot sizes, mature trees, and strong rental demand from nearby Claremont Colleges and Cal Poly Pomona makes it one of the best ADU markets in the Inland Empire. Whether you want a detached unit for aging parents, a rental on a deep R-1 lot, or a junior ADU carved from an existing footprint, we design to your property and your goals.

Because Upland is home, our team can meet you on-site quickly, navigate the city’s review process firsthand, and keep the build close to the people managing it. That proximity is part of why local homeowners consistently describe the experience as smooth and stress-free.

ADU rules & permits in Upland

Reviewed by the City of Upland Planning Division

Backyard Estates handles the entire permitting process for you. Here’s what California’s statewide ADU law means for your Upland 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.
