"We asked about bringing a wall up to modern fire code so we can install major electrical equipment without worry. Bay Easy offered an inspection and quote on a schedule far quicker than we expected, then was able to plan and execute work on a tight turnaround, too. Ofer and his team were also great about telling us when demolition revealed existing problems and offering ways to deal with those issues without leaving us feeling pressured to accept expensive additions to the contract. They were then able to execute the additional work we chose while still staying within the original timeframe."

"I had an amazing experience with Be home Remodeling, I want to thank Josh Zack's and his team of dedicated professionals for the amazing job they did on my master bathroom. Josh?s dedication and communication was crucial in ensuring the job was done quickly and professionally. He was is always available and provided quick response! We decided to do a bathroom remodel a couple of weeks ago. The entire process was done properly and as described to me at the start. Project was on schedule and went extremely smooth. The workers and staff were really professional, polite and easy to work with. I highly recommended BE Home Remodeling and specifically Josh Zack."

"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."

"Prosper and the team at Prosper Construction just completed a beautiful renovation of my home. I badly needed new flooring and decided to add other updates as well. So we embarked on the journey to design an addition to our home and redesign the entire front of the house, which included a kitchen remodel as well. I knew that I wanted to replace my carpet with porcelain tile, but I thought that I would leave my existing kitchen tile in place, to save a little money. Prosper convinced me to eliminate all transitions in the flooring and replace the entire house with the new tile, and I am really glad that he did! The house now has a smooth flow and an expansive look that is just gorgeous. The entire experience was beyond worth the investment. The most amazing part of the transformation of my home is my stunning new master bathroom, which Prosper also advised me on."

FAQs for addition to existing structure building service projects in San Francisco, 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.
