As a full-service accessory dwelling unit builder, they guide clients through every phase of the project — from the very first conversation to the final inspection. Their process is broken down into three clear stages: Plan, Design, and Develop.

Planning and Design: Turning Your Vision Into a Blueprint

The journey begins with a detailed initial consultation. During this stage, they take the time to understand the client's vision, lifestyle, budget, and desired features for their ADU. Following this, their team conducts a thorough site assessment to evaluate the property and identify any feasibility considerations or potential limitations.

Once the groundwork is laid, they present preliminary design concepts that reflect the possibilities unique to each property. From there, clients can choose between a fully custom design or one of the team's pre-approved plans. Their experienced architects and designers work closely with each client to develop a personalized accessory dwelling unit plan tailored to their specific needs and preferences.

As a knowledgeable ADU contractor, they also manage all permitting paperwork and ensure full compliance with local zoning codes and restrictions — taking the administrative burden off the homeowner's shoulders entirely.

Construction: Quality-Driven Building With an In-House Team

What sets this detached ADU builder apart is their commitment to keeping all construction work in-house. They do not use subcontractors. Every member of the construction team is a direct employee, ensuring consistent communication, accountability, and craftsmanship throughout the build.

Their skilled crew brings each granny flat or backyard cottage design to life using high-quality materials and efficient building practices. Strict quality control standards are maintained at every stage of construction to ensure the finished product exceeds expectations.

To close out each project, they coordinate directly with local building inspectors to confirm that the completed ADU meets all applicable safety and code requirements. This end-to-end approach makes them a trusted choice for homeowners looking for a reliable and professional ADU builder in the greater San Diego area.

"I have spent the last four nights sleeping in my brand new ADU. We are very happy with CRS. The quality of their work is apparent every step of the way. The communication was excellent and we always knew at what stage we were at and what was coming next. Their subs were very polite very neat and they work was excellent. I am very happy with the finished product and would recommend CRS highly to anyone considering a construction project."

"When you work with Benny, you can trust what hes telling you. Hes communicative and transparent with pricing and timelines. He very much cares about the customer experience throughout any project and customer satisfaction with the result! With most construction projects, unforeseen problems arise big and small and it can be really difficult to figure out what to do about those issues. With Benny, hes always responsive, calm and collected, and hes positive that there will be a solution that works for you. Ive had him complete a few projects in my home and he always works expediently without compromising quality. When I was dissatisfied either some of the work, he had the crew come back out and make it right! The one time he wasnt available for a project, I used a different contractor, and I ended up going to him to help get the mistakes fixed and sure enough, he stepped in and fixed things and really put me at ease. I definitely recommend working with Benny!"

"I recently had the pleasure of working with CRS Builders for the construction of an Accessory Dwelling Unit ADU at my home, and I couldnt be more satisfied with the experience. From start to finish, the team displayed exceptional professionalism and kept me consistently updated on all moving parts of the project. A special shoutout to Alona and Benny, whose hard work and dedication made a significant difference throughout the process. They were not only highly knowledgeable but also a joy to have around. Their commitment to quality and attention to detail were evident in every aspect of the build. The project progressed swiftly, and I was particularly impressed by their ability to pass all city inspections without a hitch. Navigating city building and planning regulations can often be a challenging experience, but CRS Builders handled everything with ease. They even took the initiative to manage the complexities with SDGE regarding ever-changing plans in relation to the electric meter position, which alleviated a lot of my stress and frustration. The final result is an absolutely stunning ADU that has garnered compliments from city officials, who remarked on its quality in comparison to other ADUs they have inspected. If youre considering building an ADU or any other construction project, I highly recommend CRS Builders. They made the entire process seamless and enjoyable, and the outcome speaks for itself!"

"Our project went from bad to NIGHTMARE quick! We were looking to renovate the interior of our house and add insulation. We discovered, undisclosed, structural fire damage. CRS Builders worked with us throughout the entire NIGHTMARE project. They are AMAZING!! Professional and CONSTANT communication. Construction time was absolutely incredible. They stuck with us through the 3 years of work it took to work all the issues. All while providing us with great guidance. Help great contractors by using their services!"
