Design, Permitting and Construction Across Orange County

Orange County work runs out of our Fullerton office. Larger lots make detached ADUs and additions more feasible than on the Westside, while commercial work concentrates around retail, restaurant and office tenant improvements.

Orange County questions

Do you handle commercial tenant improvements in Orange County?

Yes, including office, retail and restaurant build-outs, with health department and fire authority sequencing managed alongside building plan check.

What does an ADU cost in Orange County?

Similar ranges to Los Angeles, roughly $250 to $450 per square foot for detached units, with garage conversions lower. Larger lots often reduce utility routing cost compared with dense Westside sites.
