Permits & fees
Red tape in Covina, 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 Covina Community Development Department
What California’s statewide ADU law means for your Covina 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 Covina permit and city fee into one fixed, all-in price.

Local know-how
Why homeowners build in Covina
Covina homeowners tend to value exactly what we do best: a reliable, transparent process that finishes on time and on budget. One Covina family told us we were on time, stuck to the price, and made the whole thing seamless — that is the standard we hold across the San Gabriel Valley.
Covina’s mix of mid-century neighborhoods and walkable downtown means a range of lot sizes, from comfortable R-1 parcels north of the 10 to tighter lots near the Metrolink station. Transit proximity near the station can remove added-parking requirements, which helps for rentals. We size and place each ADU to the specific lot.
Covina is a straightforward drive from our Upland office, and we keep your project close from permit to move-in.
