Can't thank David and Ariel enough for helping me get my bathroom remodeled. I originally reached out to get my flooring done. I was so happy with how the floor turned out that I called them back to have my bathroom remodeled. The whole process was seamless from start to finish and would highly recommend them to all my friends and family! Joe SindicichTrustindex verifies that the original source of the review is Google.

Very happy we chose them !! shelly vaughnTrustindex verifies that the original source of the review is Google. I can’t thank Ariel and his team enough for all their hard work and expertise with my remodel. When we first met Ariel to discuss remodeling our bathroom we did not expect that our bathroom could be transformed into such a beautiful new bathroom. Truly thankful to the First Builders team for assisting me with getting the bathroom remodeled! Thank you guys! Miki BornTrustindex verifies that the original source of the review is Google. Very good experience remodelling my kitchen and bathroom with First Builders. David was very responsive to requests and issues and the team delivered good quality of work. Only thing is we didn't have enough tiles ordered in the first time so had to wait extra time for additional ones to arrive. The outcome in the end looks awesome and they are very attentive to details. They are NOT the cheapest quote I got but the service is worth the premium. Denise EutseyTrustindex verifies that the original source of the review is Google. I just want to take a moment to thank Ariel and his team for their hard work and expertise. When I first reached out to Ariel about getting new flooring in my bedrooms, Ariel guided me through the process and provided me with several options that were within my budget. I could not be happier with the overall experience and final result. Thank you Ariel! Gayane MkrTrustindex verifies that the original source of the review is Google. We built a 900 sqft detached ADU in our backyard with vaulted ceiling, beautiful custom cabinets, white oak floors and upgraded windows and doors. Our architect recommended Ariel , he was absolutely incredible. We couldn’t be happier with our decision. Highly recommended!! Daniel ChavezTrustindex verifies that the original source of the review is Google. Have nothing but good things to say about this company! First of all, they are super responsive and helpful which was very important for me while seeking a contractor because I know how many details are involved in renovating a house. Secondly, they work FAST. These guys don’t play around. If you want to remodel your home don’t hesitate twice and go for it. Ariel is a sweetheart and it shows that he knows what he is doing/talking about. A real professional in the full sense of the word.

A bathroom remodel is one of the highest-ROI upgrades you can make in Southern California. In Los Angeles and surrounding areas, updated bathrooms can return 70–90% of your investment at resale while instantly improving daily comfort, water efficiency, and home wellness. Whether you crave a serene primary suite, a family-friendly design, or a timeless guest bath, First Builders Inc. turns dated spaces into luxurious retreats you’ll love every single day.
As your local family-owned experts, we handle everything with complete transparency—from structural reinforcement and plumbing upgrades to heated floors and custom vanities. Our proven process keeps disruption low and beauty high, delivering spa-quality results that stand the test of time.
A garage conversion ADU is a fully independent living unit created by transforming an existing attached or detached garage into a complete home with kitchen, bathroom, and private entrance. California’s ADU laws make garage conversions one of the simplest and most affordable options, and our expert team at First Builders Inc. delivers seamless, code-compliant results with beautiful craftsmanship.
In the Los Angeles area, a typical garage conversion ADU costs $120,000–$250,000 depending on size, finishes, and utility upgrades. This is significantly less than new detached construction. We provide transparent, detailed estimates upfront so you know exactly what to expect with no surprises.
Yes, a building permit is required, but California’s streamlined ADU rules mean approvals are fast and ministerial (usually within 60 days). First Builders Inc. handles the entire permitting process for Los Angeles, Orange County, and surrounding areas, saving you time and stress.
No. Under current California law, garage conversion ADUs are exempt from parking replacement requirements, even if the garage was previously used for parking. This makes conversions especially attractive in space-constrained neighborhoods.
Yes, you can rent it long-term or, where local rules allow, short-term (Airbnb). There is no owner-occupancy requirement for garage conversion ADUs, making them an excellent source of passive rental income. We design and build rental-ready units that attract quality tenants.
Most garage conversion projects take 4–7 months from permit approval to final sign-off, far faster than ground-up construction. Our experienced family-owned team keeps your project on schedule while maintaining the highest standards of quality and communication.
Absolutely. A well-built garage conversion ADU often adds $200,000–$400,000 or more to your home’s value while providing immediate rental income potential. At First Builders Inc., we focus on timeless design and superior construction that maximizes both resale value and daily enjoyment.
Garage conversions typically tie into your home’s existing water, sewer, and electrical systems, which keeps costs lower than new detached units. In many cases, only minor upgrades are required to meet code. At First Builders Inc., our Los Angeles team handles all utility connections seamlessly, ensuring your new ADU is fully independent, energy-efficient, and ready to use without surprises.
