In Their Own Words
"Working with Peninsula Construction was a great experience. Richard and his team were always on time and maintained a clean work site. Richard took care of all the city inspections and really helped finish my 750 square foot ADU in about 5 months. I was so happy with their work I even had them build a 24 foot gazebo right next to it."
"I hired Peninsula Construction for a full kitchen remodel at my home in Monterey, CA and it was an outstanding experience. Richard walked me through every step of the process, and his expertise really showed when it came to making the right decisions to ensure everything came together perfectly. The entire team was professional and a pleasure to work with. I've already recommended Peninsula Construction to family and friends. Couldn't be happier with the results."
"After the city flagged my unpermitted garage in San Jose, I called Richard at Peninsula Construction. He handled everything from start to finish, got it permitted, approved, and completely redid the layout to maximize the space. It's now classified as a legal garage conversion ADU, which means I can still build a detached ADU on the property too. Peninsula Construction is already working on the new 749 square foot 2-bedroom detached ADU. The garage ADU is already rented out and I couldn't be happier. Highly recommend Richard and his team."
"I hired Peninsula Construction for a kitchen remodel and full roof replacement at my home in Watsonville, and I could not be more pleased with the results. Richard and his crew were professional from start to finish, treating the job with the same care they would give their own home. The crew was always on time and cleaned up the work site at the end of every single day. Richard gave me a clear timeline and delivered right on schedule. I would highly recommend Peninsula Construction for any job big or small."
