"I hired LEES PRO BUILDER to install a structural header, and they did an outstanding job. The work was completed quickly, and the quality was excellent. The installation was clean, precise, and professionally done. The team was punctual, efficient, and communicated clearly throughout the project. Everything was completed as promised, and the finished result exceeded my expectations. I highly recommend LEES PRO BUILDER for anyone looking for reliable, high-quality construction work."

"We worked with Or Avrahami from Brother and Brother to completely remake the interior of our home (the previous owner's had lived there 40+ years). The renovation included two new bathrooms, a new kitchen, turning a 3 BR into a 4 BR by moving / building interior walls, new wood floors, and the removal of a large interior wall. We couldn't be happier with the final result and we appreciate Or working with us to ensure that the quality of each component was top notch, to our liking, and within budget."

"We had an amazing experience with Sigura Construction on our backyard transformation project. They did a fantastic job building a swimming pool, outdoor kitchen, landscaping with pavers, and custom lighting. The entire crew was incredibly professional, thorough, and efficient, delivering top-quality work from start to finish. Ilan, the owner, was outstanding—easy to communicate with, professional, and highly knowledgeable about all the options for our project. He made the entire process seamless and stress-free. Our backyard now looks absolutely stunning, and we’re thrilled with the results. We have complete peace of mind knowing the work was done by true experts. We highly recommend Sigura Construction to anyone looking for exceptional construction services. Thanks again to Ilan and the team for a job well done!"

"After meeting with around 10 contractors, I decided to go with EA Homebuilders. Eric seemed honest and willing to do our remodeling the way we wanted it done. Great decision. Eric, Hector and crew were courteous and finished the job in the time they said it would be done, less than a month. We love our new bath/ shower. Highly recommend and would use again."

FAQs for garage building service projects in Sunnyvale, CA

A well‑constructed, properly permitted detached garage adds between $12,000 and $36,000 to a home’s resale value. Buyers appreciate the secure parking, extra storage, and flexible workspace, so appraisers often bump the property’s value accordingly. The exact return depends on the garage’s size, finishes, and how well it matches the main house, but most homeowners see a strong ROI when the build meets local codes and passes inspection.

Yes—once it meets local building codes and you secure the proper permits, a detached garage can be converted into living space. Finishing the interior, adding climate control, and ensuring safe egress effectively increase your usable square footage, though it may not always count toward the official listing. Skipping permits can trigger fines and even force you to undo the work, so always clear plans with your city first.

Most homeowners policies cover a detached garage under the “other structures” provision, but coverage limits vary. Review your declarations page and ask your agent how much protection you have for separate structures. If the limit is lower than the garage’s replacement cost, you can raise it for a modest premium. Confirming the details now prevents headaches if you ever need to file a claim.
