About Us

Welcome to Ritz Design Build, your trusted San Diego general contractor and home builder since 1965. With nearly 50 years of overseeing home remodeling projects, such as room additions, second story additions, kitchen/bath remodels and complete floor to ceiling home design and build projects, we have the expertise to handle all your home remodeling needs.

Because we are not a mega-company (nor desire to be) and only provide services with the quality and personal support our clients deserve, we do a limited quantity of new home and custom renovations each year. We use state-of-the-art software to visually portray your new dream home in an intimate setting. Ritz Design Build impresses with superior designs and quality craftsmanship for a fair cost. Your hard earned monies are spent where they should be, on “Your Home”; not on our facilities or with expensive fancy television ads.

With only 5-Star reviews and thousands quality new builds and renovations throughout San Diego since 1965, our history of continued success and happy, satisfied homeowners stands testament to why Ritz Design Build is the best choice for you.

RITZ Design came in and saved us after we had found out that our architect’s permitted plans that had taken 4 months and $7500, were unbuildable. They not only drew up new plans and got the permits for us but assisted us in getting a refund from the old permit. Our addition of a bedroom and dining room went up in just a few weeks and the guys from RITZ Design were not only professional and efficient but also very hardworking and considerate of our young children and dogs. They went above and beyond at every turn and we are so happy with our new space. We look forward to working with Ed Ritter and the whole team in the future. Thanks guys!!!
