Garage Conversion ADUs in Los Angeles County
Converting an existing garage into a legally permitted Accessory Dwelling Unit (ADU) has become one of the most efficient ways for homeowners in Los Angeles County to increase livable space and generate long-term rental income without expanding their property's footprint.
Garage-to-ADU conversions are particularly common in coastal and South Bay communities such as San Pedro, Torrance and Long Beach, where zoning allowances and state ADU legislation make it possible to convert detached garages into independent residential units.
While California state law allows garage conversions by-right in many residential zones, local building departments still apply jurisdiction-specific development standards that affect setbacks, ceiling height, energy compliance and fire separation requirements. Properties located within the City of Los Angeles are reviewed by the Los Angeles Department of Building and Safety, while homes in Long Beach must comply with regulations enforced by the City of Long Beach Development Services.
Because of these municipal differences, garage conversion ADUs in the South Bay often require site-specific planning strategies in order to meet local zoning requirements and avoid delays during plan check review.

ADU Garage Conversion Permits in South Bay Cities
Garage conversion ADU permits are processed differently depending on the jurisdiction in which the property is located. Homeowners in San Pedro typically submit ADU conversion plans through LADBS, where structural compliance, Title 24 documentation and independent ingress/egress must be verified prior to approval.
In Torrance, garage-to-ADU conversions are regulated by the City’s Community Development Department and must comply with local residential zoning codes regarding emergency egress windows, ceiling height clearances and utility metering requirements.
Similarly, ADU garage conversions in Long Beach must meet development standards established by the City of Long Beach Development Services, particularly in relation to energy efficiency compliance and minimum insulation requirements.
Because review timelines and development standards vary between municipalities, working with a general contractor experienced in submitting ADU plans through local permitting agencies can help reduce plan check corrections and improve overall approval timelines.

Garage Conversion ADU Requirements by Municipality
Although state ADU laws allow homeowners throughout California to convert existing garages into independent living units, local municipalities within Los Angeles County still enforce zoning and development regulations that may influence the final design of the conversion.
These requirements often include:
- Fire-rated wall separation between units
- Minimum ceiling heights
- Natural light and ventilation
- Separate exterior access
- Parking exemption eligibility
Municipalities such as San Pedro, Torrance and Long Beach may also apply additional design review criteria based on lot coverage, proximity to the coastal zone or local overlay districts.
Contractors experienced in navigating permitting processes through agencies such as the Los Angeles Department of Building and Safety or the City of Long Beach Development Services can help ensure that ADU conversion plans meet all applicable building and zoning requirements prior to construction.
Do ADU Garage Conversion Regulations Differ Between Cities?
Yes. While California law allows garage conversions to be approved ministerially in many residential zones, individual municipalities such as San Pedro, Torrance and Long Beach enforce local zoning codes that may affect setbacks, utility connections and design review requirements.
Garage conversion ADU projects submitted through the Los Angeles Department of Building and Safety or the City of Long Beach Development Services must demonstrate compliance with applicable development standards prior to approval.
