Bay Area ADU Builders With One Fixed Price - No Surprise Costs. Ever.
Most builders quote low, change-order you over budget, and let permit delays burn months of your rental income. We've spent 15 years and 180+ Bay Area ADUs doing the opposite. One locked price, permits handled by people who know every city's playbook, and a tenant paying you — sooner.
Avg. Bay Area ADU rent: $2,800–$3,800/moAvg. rent-ready: 6 months

We hired Renova Builders for a full design and build project, including a two-room addition, a new master bedroom and bathroom, and a complete interior layout redesign. The experience was excellent from start to finish.
Alex, the project manager, was organized, responsive, and kept everything running smoothly on site. Omri, the owner, was involved and made sure the quality stayed high throughout the project. Stefani and the office team handled coordination and communication efficiently, which made the whole process easy.
The crew delivered beautiful, high-quality workmanship with great attention to detail. The project was completed on time and at a fair, transparent price.
Highly recommend Renova Builders for anyone looking for a reliable and professional design and build company.

I've worked with a lot of builders in the Bay Area, and Renova Builders is honestly one of the few companies I can recommend without hesitation. Omri is solid. He shows up, he communicates, and he actually cares about the quality of the work.
From the beginning, he made the whole process straightforward. If something needed attention, he pointed it out early and offered practical solutions instead of excuses. His crew worked clean, stayed on schedule, and the craftsmanship was consistently high.
As someone who specializes in new construction, I don't hand out compliments easily, but Omri and Renova earned it. They're reliable, professional, and easy to work with. I'd work with them again any time.

We recently completed a full house remodel along with a complete kitchen renovation, and the experience exceeded our expectations from start to finish.
The design phase was thoughtful, detailed, and truly elevated the entire project. Bill did an excellent job guiding the design direction, helping us make the right choices while keeping everything functional and high-end.
Omri, the owner, was involved throughout the process and made sure everything stayed on track. His professionalism, knowledge, and commitment to quality were clear in every stage of the project.
Alex, the foreman, was fantastic on site. He kept the job organized, the crew moving efficiently, and maintained a high level of workmanship. It made a big difference knowing someone experienced was managing the day-to-day so closely.
Stephanie, the office manager, kept everything running smoothly behind the scenes. Communication, scheduling, and coordination were handled quickly and professionally, which made the whole process stress-free.
The final result speaks for itself. The kitchen is stunning, and the entire home feels like a brand new, luxury space. High quality work, attention to detail, and a team that truly cares.
Highly recommend for anyone looking for a full home remodel or kitchen project.

We completed a full house renovation with Omri, and the experience was excellent from start to finish. The project management was outstanding, everything was clearly planned, well organized, and communicated transparently throughout the process. The work was delivered on time, which is rare and highly appreciated for a renovation of this scale. Attention to detail, professionalism, and reliability were consistent every step of the way.
Omri truly delivered a high quality renovation with no shortcuts. Highly recommended for anyone looking for a full house renovation done right.

I've been working with Omri from Renova Builders for many years now, on everything from small bathroom remodels to full new construction projects. Omri is a true professional and always a man of his word. Communication is clear, direct, and respectful, whether it's with subcontractors, homeowners, or clients.
I've seen firsthand how he runs his projects, and it's impressive. Everything is organized, expectations are clear, and the job always moves forward the right way. It's not common to find a contractor who manages both people and projects at this level.
Highly recommend working with Omri and Renova Builders.

Omri and the entire team at Renova Builders did an excellent job repairing and refinishing the three story redwood deck at our two-unit Eureka Valley condo in San Francisco. The team was very reliable, communicative and hard-working. Renova had refinished this same deck several years ago, and we will certainly use them again in the future. I have no reservations at all about highly recommending this company to others.

Renova Builders is an excellent full service general contractor that goes above and beyond to ensure customer satisfaction. I went out on a limb with a Google Search and found Renova, and now we feel like we have a strong lasting relationship.
Omri, the owner, was a pleasure to work with and brought significant experience and ingenuity to help us achieve our dream on two projects which had a high degree of complexity. Omri's subs were excellent and highly professional, and the craftsmanship was second to none.
I was especially impressed by Omri's ability to marshal the right people to get the complex work done which included interior design to upgrade two interior spaces and included some all the different trades and finishing. Omri was also very fair on his pricing, and is on point, which you want from a contractor-he actually moved very quickly and efficiently to the point we were the ones playing catch up. A true professional in his approach to getting things done. He would check in on site every opportunity and kept on his subs and his communications with us were very good throughout the entire project.
Renova is capable of doing it all from the ground up, and is a solid contractor in the Walnut Creek, La Morinda, and Tri-Valley area that I highly recommend, especially if you have a quality construction home and care about craftsmanship. Omri is the man!

Renova Builders was recommended to us through a friend, and we hired them to work on our house. We were absolutely thrilled to have Renova Builders on board for our kitchen renovation. They did an amazing job of staying within our budget for the cabinets, countertops, and everything else. We couldn't be happier with Alex, the project manager. His expertise and assistance in selecting the materials were invaluable. He was always there when we needed him, making the whole process a breeze. And Stephanie, the office manager, was on top of everything, ensuring all the deliveries were on time. The results were beyond our expectations, and we were so impressed that we decided to have them renovate our primary bathroom as well. We wholeheartedly recommend working with Renovo Builders, especially with Alex leading the way. Trust us, you won't be disappointed!

Straight answers
The Three Questions Everyone Asks. Answered.
How much will it cost?
Exactly what your quote says - that's the whole point. One fixed price for design, permits, and construction, locked before we break ground. In 180+ ADUs, our clients have never paid a change order. The calculator above shows the ballpark; your free quote shows the exact number.
How long will it take?
About 6 months from permit to rent-ready - roughly half the Bay Area average of 12–18. We've run the permit process in every city on that dropdown for 15 years; that's where the other guys lose your months.
When do I start making money?
Around month 7 - first tenant, first rent check. From there, rent covers your financing while the unit adds hundreds of thousands in property value. You profit twice: monthly cash and equity from day one.
The only question left is what your property's numbers look like.

At Renova, every detail matters, from foundation to final finish, because the quality we put in is the value - and the rent - our clients get out.

How it works
Six Months to Rent-Ready. Here's the Path.
Clear milestones from first call to first tenant - one project manager, one fixed price, one timeline we commit to in writing.
Site visit, rent comps for your street, and your fixed price - the exact number, not an estimate.
Plans engineered for your lot and for permit approval the first time - no redesign loops.
This is where other builders lose months. 15 years in every Bay Area city's process means we submit it right the first time.
One in-house crew, weekly updates, zero change orders. The price you signed is the price you pay.
Final walkthrough, keys, and rent comps in hand to list immediately. First rent check: ~month 7.
Every Month You Wait Is a Rent Check You Don't Get.
Your free quote takes one visit and costs nothing: your exact fixed price, rent comps for your street, and your timeline to the first tenant. Then the numbers decide - not us.
