Accessory dwelling units (ADUs) are one of the best ways to add value to a property, especially in the Bay Area, where there is a perpetual shortage of housing. I have found that one great way to add an ADU is by converting an existing garage to an ADU. This converts inhabitable space into a complete unit with kitchen, bathroom, and bedroom.
One project I did was the planning and execution of a garage conversion. ADUs have all the complexities of a whole house, constrained by a small package. They require all the same electrical codes, kitchen and bathroom complications, and structural analysis a large house needs just to name a few. The ADU I built started as a neglected garage and needed complete renovation. I designed the layout and complete plans, involving moving structural walls, adding plumbing, electrical, earthquake reinforcement, and complete refinishing. I did a title 24 analysis, which is required for all California projects as well.
I also managed the contractors who executed the project. There were 5+ teams I managed, These teams did plumbing, electrical, windows, and others. Even with all the plans in place, every day has the potential to be different and unexpected. For example, a piece of wood found embedded in the foundation meant an unexpected change of plans while we got it removed and filled.
Here are some rough photos to showcase the process.
