Frequently asked questions
How much does an ADU cost in Los Angeles?
ADU cost varies based on size, design, site access, utilities, foundation type, and finishes. We provide a detailed estimate after a site review in Los Angeles.
Do you handle permits and plan sets for ADUs?
Yes. We can coordinate design/engineering, plan submittal, and permit tracking so the process stays organized.
What’s the difference between an attached ADU, detached ADU, and JADU?
Attached connects to the main home, detached is a separate structure, and a JADU is typically created within the existing footprint with specific requirements.
How long does an ADU project take from start to finish?
Timelines depend on design and permitting, but a typical path is: design + plan check, then construction. We’ll map the schedule clearly before you commit.
Can you build an ADU above a garage or convert an existing garage?
Often yes, depending on structural conditions and local rules. We evaluate the existing structure and recommend the fastest compliant approach.
Do you help with utility hookups (power, water, sewer)?
Yes. We coordinate utility tie-ins and inspections, and we design the layout to minimize trenching where possible.
Will adding an ADU increase my property value?
Many owners add ADUs for rental income and long-term value. Exact outcomes depend on location, finish level, and market conditions.
Can you build a small ADU or studio layout?
Yes. We can design efficient studios and 1-bedroom plans that maximize storage, light, and privacy.
Do you offer financing options?
If you’re using financing, we can provide scopes and documents lenders typically request. We can also align milestones to draw schedules.
What site conditions make an ADU harder?
Tight access, steep slopes, limited utility capacity, and complex setbacks can add complexity. We identify constraints early.
Do you handle inspections during construction?
Yes. We coordinate required inspections and keep a punch list so the final sign-off goes smoothly.
Can you match the ADU exterior to my existing home?
Absolutely. We can mirror rooflines, siding materials, window styles, and colors so the ADU looks original to the property.
