Northbay Home Solutions – ADU Contractor in San Rafael, CA

About Northbay Home Solutions

ADU Construction Services by Northbay Home Solutions

Northbay Home Solutions specializes in custom ADU construction throughout San Rafael, San Francisco, and the broader North Bay region. Their team works as an ADU contractor managing projects from initial design through to final inspection, covering detached ADUs, garage conversions, and junior ADUs (JADUs).

Accessory dwelling units have become one of the more practical ways for homeowners in Northern California to add living space, generate rental income, or increase property value. Updated California ADU laws have made the construction process more accessible, which has contributed to growing interest across the region.

Local Knowledge and Regulatory Expertise

Building an accessory dwelling unit involves navigating a range of local regulations, and requirements can vary significantly between jurisdictions. Northbay Home Solutions works across San Rafael, San Francisco, and Marin County, giving them familiarity with the specific zoning rules and building codes that apply in each area. This local knowledge helps keep projects compliant and on track.

As an experienced ADU builder, they design and construct a range of unit types, including:

  1. Detached ADUs
  2. Attached ADUs
  3. Garage and basement conversions
  4. Junior ADUs (JADUs)
  5. In-law suites and backyard cottages

Each unit is custom-designed to work with the existing property while making practical use of available space.

Homeowners in the North Bay area are building ADUs for a variety of reasons. Common uses include generating long-term rental income, setting up short-term rentals where local rules permit, creating a dedicated home office or studio, or providing housing for family members or aging parents. An ADU can expand what a property offers without the expense of purchasing additional real estate.

Full-Service ADU Process

Northbay Home Solutions positions itself as a full-service ADU contractor, offering a turnkey approach for homeowners in San Rafael, San Francisco, and surrounding North Bay communities. Their process covers the full scope of a project, including:

  1. Property evaluation and feasibility assessment
  2. Architectural and structural design
  3. Permit preparation and city approvals
  4. Foundation, framing, and structural construction
  5. Plumbing, electrical, HVAC, and utility installation
  6. Interior finishes and exterior detailing
  7. Final inspections and project close-out

By handling each stage of the process, Northbay Home Solutions aims to reduce the administrative burden on homeowners and keep projects moving efficiently from start to finish. Whether the goal is a detached ADU, a garage conversion, a granny flat, or a JADU, their team works to deliver a finished unit that meets both local requirements and the homeowner's practical needs.

"Northbay Home Solutions Constructions just met our needs with the construction of our handicapped bathroom project. The project was within our budget and was completed on schedule. Daily updates on the project was always forwarded to me by Mike the owner, and Jessica the project. manager which efficiently kept us informed with aspects of the project. Mike and Jesica's response to any of our questions were always available immediately. Although this was our first project together, it appeared as if we had known each other for years, with such a warm and courteous relationship, particularly up dating us on things that would be happening in the coming days and weeks. Our confidence in this company urged us to issue a Certificate of Appreciation to Mike on the very day that our project was completed. With high commendation. Rev. Tevita Koroi."

"We recently remodeled three bathrooms in our home in Tiburon. Jessica and Jose with Northbay Home Solutions were amazing. Jessica was our project manager from start to finish. It was very convenient to deal with one person through the entire project."

"I met Mike Quinn months before we started our project and the time and energy he put into that first meeting was the same as the time and energy he put into our entire project. He has always been very responsive! They put together a WhatsApp text string and when we had any questionconcern or request we would text and most of the time there was a response almost immediately and if it wasn't immediate it was within a few hours. Mike's team was thoughtful, respectful and always helpful. Jessica, his project manager, was extremely helpful with starting the project and helping me make decisions as well as making sure all aspects of the project were on time and made sure that I had the materials on hand or at least ordered. They gave me a list of things that I would need for my project, suggestions on where to buy them as well as passing along the discount that they get at each recommended supplier. We couldn't be happier with our experience and the end product! His crew worked 6 days a week and the ONLY reason the job wasn't completed on time was that we kept adding projects because we were so very happy with the progress. Weekly, Jessica or Mike would let us know what to expect for the week and what would be completed. This entire crew was professional and courteous and we would highly recommend them for any project. As a matter of fact, we have sent several friends and neighbors to them and they are working on a few of those projects as well. I've added some before and after photos below of the kitchen and then photos of two of the bathrooms that they remodeled. But they also updated our electric panel, installed an Electric car charger, on demand hot water heater, heated floors in the bathrooms, skylights, outside flashing that was causing a leak, resealed and regrouted our paver driveway, fixed our retaining wall and then painted our entire interior - walls, crown molding and ceilings. You can count on Mike and his team to do a great job. And one more note, of course there were a few minor things that needed to be addressed after the project was completed and they have come back and taken care of everything quickly and efficiently!"

"My son's, husband and myself began adding 2 ADU units in July of 2023. Mike - Northbay Construction was one of the 5 general contractors we interviewed with plans to convert 2 garages into 2 - 2 bedroom - 1 bathroom - 700 square foot apartments in SF. He seemed to be knowledge of the challenges of taking on a project this size on and the knew the workings of the City Building Department. He quickly gave us a quote. Explain to us we could work with his vendors for cabinets, flooring, plumbing fixtures etc. He said he would finish within 11 months and was right on schedule. Mike has his own team of sub contractors always ready to start the next project and made a very smooth transitions throughout the project. There were very few days where there was no one working on the project. Every team was dedicated to completing the project as soon as possible. Mike provided excellent communication whether weekly Zoom calls, emails or text. With 4 owners, he worked with all of us making sure we were all updated. His crews were wonderful to work with and Jessica his assistant was always available for questions and follows up on concerns, keeping us posted on the project and working with all owners. The detail of the work and finishes was excellent. I would definitely recommend Northbay Construction. They are an excellent team!"

"Home improvement projects are generally never easy endeavors for a variety of reasons, but working with Mike and team at Northbay Home over the past year was fantastic, and a lot of fun as we transformed ideas into new features of our home. We worked with Northbay on several projects over the past year, starting with a guest bathroom remodel, and expanding to some important electrical work and a new fence build that gave us an upgraded look and increased privacy. The work done by the team was high-quality and top-notch, and delivered within expected timelines. When unexpected things did pop-up, Mike was quick to respond and resolve the issues. And as a result, we are genuinely happy with the final products. Mike is a true professional, and this is quickly demonstrated by the depth of his knowledge, the quality of his ideas and solutions, and his attention to detail when consulting with customers. We enjoyed our experiences with Northbay, and would work with them again."
