West Hollywood is one of the highest-density, highest-rent small cities in Los Angeles County, and one of the most compelling markets for ADU construction. Single-family properties in West Hollywood are rare and valuable — homeowners who add an ADU are creating rental income streams that dramatically improve the economics of ownership in one of the most expensive zip codes in the LA area. APLA Construction (CA Lic #1136359) builds ADUs throughout West Hollywood, managing City of West Hollywood permits, design, and construction under one contract.
The majority of West Hollywood single-family homes have detached garages, many accessed from alleys behind the property. Converting an existing garage to a full ADU is the most cost-effective ADU path in West Hollywood.
Where lot size permits, a new detached ADU in the rear yard can deliver premium rental income in West Hollywood given the location premium this neighborhood commands.
