City-Specific Zoning Requirements
Los Angeles zoning laws determine where ADUs can be constructed and what types are permitted. Most residential zones allow at least one ADU per lot, but setbacks, lot size, and unit size limits vary by neighborhood.
For example, some areas have restrictions on ADU square footage relative to the primary residence, typically capping at 1,200 square feet. Additionally, parking requirements are often waived for ADUs located near public transit, but in some zones, one off-street parking space may still be required.
Building Codes and Safety Standards
ADUs in Los Angeles must comply with the California Residential Code and local amendments. This includes regulations on foundation type, structural integrity, fire safety, plumbing, and electrical systems.
Key safety elements involve smoke detectors, emergency exits, and energy efficiency standards under Title 24. We ensure plans meet seismic safety requirements unique to Los Angeles, which impacts design and materials.

ADU Zoning and Code Compliance Assistance FAQs
What are the current ADU zoning requirements in Los Angeles?
Los Angeles allows ADUs on all single-family and multi-family residential lots under state and local regulations. You can build one ADU plus one Junior ADU (JADU) on single-family lots, with ADUs up to 1,200 square feet and JADUs up to 500 square feet. Multi-family properties can add one ADU per existing unit, with a minimum of two ADUs allowed. The city follows California's streamlined ADU laws, which preempt most local restrictions and require ministerial approval for compliant projects.
Do I need a permit to build an ADU on my property?
Yes, you need building permits for all ADU construction in Los Angeles. This includes structural, electrical, plumbing, and mechanical permits depending on your project scope. ADU permits are processed ministerially, meaning approval is required if your plans meet code requirements. The permitting process typically takes 60-120 days, and you'll need approved plans, site surveys, and various compliance documents.
How do I know if my lot is eligible for ADU construction?
Most residential lots in Los Angeles are eligible for ADU construction, but specific factors determine feasibility. Your lot must have adequate space for required setbacks, parking, and utility connections. We evaluate your property's zoning designation, existing structures, easements, and covenant restrictions. Key considerations include lot coverage limits, height restrictions, and access requirements.
What are the setback requirements for accessory dwelling units?
ADU setbacks in Los Angeles are generally more flexible than main dwelling requirements. Side and rear setbacks can be as little as 4 feet for structures under 16 feet in height. Front setbacks must maintain 20 feet from the street or match the existing main dwelling's setback. Converting existing structures like garages often allows you to maintain current setbacks.
Can I build an ADU if I'm in a historic district?
Yes, you can build an ADU in a historic district, but additional design review and approval processes apply. Historic Preservation Overlay Zones (HPOZ) require that ADU designs complement the neighborhood's historic character. You'll need approval from the local HPOZ board in addition to standard building permits. Design guidelines typically address architectural style, materials, and placement to ensure compatibility. The process takes longer than standard ADU approvals, but experienced professionals can navigate these requirements to achieve successful project approval.
