Ritz Design Build, has served all of San Diego County as a design-build contractor since 1965.Their specialty is designing and building Accessory Dwelling Units, ADU's, and custom home additions, such as Master Suites, Family Rooms, Granny Flats (ADU's) Kitchen Extensions, and Second Stories. They also offer a 3D design service on all qualifying projects. This service allows homeowners to visualize their completed projects during the initial design stage. The service includes both interior and exterior 3D renderings and floor plan options. Put their 55 years of tried & true experience to work for you and see why so many of your neighbors have already chosen Ritz Design Build to design and build their home addition.

"From the first meeting with Ed and Claudia, my family knew we were in great hands. They listened to our needs and wants and offered advice to help us make the best decisions for our family. During the design process, all the details we reviewed and the team listened. The final design was exactly what I wanted. Once Ritz began the remodel, I was kept in the loop from permits, inspections, timelines, and everything else. I was never guessing. The project manger, Aiden, listened to all my questions and made sure I understood each decision made. When it came to the details, Aiden was always a phone call away. He spent hours working to make sure everything was perfect and that I was happy with the end results. Ritz was professional and timely and even completed the project within in the timeframe (over a month earlier than projected). During demolition, the crew worked to overcome any challenges that came their way. The construction process moved quickly and each team was professional. All subcontractors were part of the team ( plumbing, flooring, painting, etc.) they always were professional and answered any questions I had. Even during a pandemic, Ritz was able to design and build my dream home. I appreciate all their hard work and dedication to the remodel. Aiden is knowledgeable with his skills and handy work and led the team with excellence. Eddie designed a home that met all my family needs. The crews were top notch and the best of the best. And Ed and Claudia always treated us like family when we met. If you need your home remodeled, Ritz is the company for you."

I started "I'll Handle It" to address what I recognized as a need that homeowners have for competent, knowledgeable and courteous home improvement service professionals to help them with all manner of projects large and small. Founded in San Diego, "I'll Handle It" is a home grown business that prides itself in its responsiveness to its customers needs. At "I'll Handle It" "Professional Service You Can Rely on" is our mantra, and we can prove it.

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

FAQs for addition to existing structure building service projects in Alpine, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
