Question 1

How much does it cost to build an ADU in Los Angeles?

Accepted Answer

ADU construction in LA typically costs $150,000-$500,000+ depending on size and finishes. A basic 400 sq ft studio ADU starts around $150,000. Standard 600-800 sq ft units cost $200,000-$350,000. Larger luxury ADUs can exceed $500,000. This includes permits, construction, and utility connections.

Question 2

How long does it take to build an ADU in LA?

Accepted Answer

ADU construction typically takes 6-12 months total. Permit approval takes 8-16 weeks in LA County. Actual construction takes 4-8 months depending on size and complexity. We provide detailed timelines and keep you updated throughout the process.

Question 3

What size ADU can I build on my property?

Accepted Answer

California law allows ADUs up to 1,200 sq ft on most residential lots. Junior ADUs (converted from existing space) can be up to 500 sq ft. Detached ADUs must meet setback requirements. Lot coverage limits also apply. We assess your property's specific potential during consultation.

Question 4

Do I need separate utilities for an ADU?

Accepted Answer

ADUs can share utilities with the main house or have separate meters. LA DWP may require separate water/power for rentals. Gas typically requires a separate meter. We coordinate all utility requirements and connections as part of the project.

Question 5

Can I rent out my ADU?

Accepted Answer

Yes, California law specifically allows ADU rentals. Many homeowners build ADUs for rental income ($1,500-$3,500/month in LA). ADUs cannot be sold separately from the main property. Short-term rentals (Airbnb) may have additional local restrictions.

Question 6

What's the ROI on building an ADU?

Accepted Answer

ADUs offer excellent ROI in Los Angeles. A $250,000 ADU renting for $2,500/month generates $30,000 annual income. Property value typically increases by 20-30% of ADU construction cost. Most ADUs pay for themselves in 8-15 years while providing monthly income.

Question 7

Do I need to add parking for my ADU?

Accepted Answer

California law eliminated parking requirements for ADUs within 1/2 mile of public transit. Many LA neighborhoods qualify. Other exemptions exist for accessory structures or when existing garage is converted. We verify parking requirements for your specific location.

Question 8

Can I convert my garage to an ADU?

Accepted Answer

Yes, garage conversions are popular ADU options. Costs range from $100,000-$200,000 depending on size and condition. This requires upgrading foundations, adding insulation, windows, plumbing, and kitchen facilities. Parking replacement is often not required under California law.
