Long Beach is one of the fastest-growing ADU markets in greater Los Angeles. A large stock of post-war bungalows with detached garages and alleys, rising property values, and strong rental demand from the Port of Long Beach workforce, Cal State Long Beach students, and South Bay professionals create outstanding ADU investment economics. APLA Construction (CA Lic #1136359) builds ADUs throughout Long Beach — managing City of Long Beach permits, design, and construction under one contract.
The dominant ADU type in Long Beach is the alley-accessed garage conversion. Most Long Beach bungalows and ranches have 1-2 car detached garages that are ideal ADU candidates.
Larger Long Beach lots — especially in Bixby Knolls, Los Altos, and the Estate District — can accommodate new detached ADUs that deliver strong returns given the area rental market.
