ADUs, additional dwelling units, are now en vogue in California. Fueled by the WFH movement and extreme lack of housing in the San Francisco Bay Area and beyond, these either attached or detached additions now benefit from a rather streamlined permitting process. This is especially so if the footprint of one's house remains the same, i.e., using a portion of the garage in which to build the ADU. My husband and I hope to have an ADU built from a the back half of our garage extending into our back garden. There is a certain percentage of the yard that may be used for such things; I don't remember what that is right now. We do know that we are allowed to build out as far as the neighbors have done with a rather ample deck which extends about a third into their back garden. Costs are fairly dear for such projects. It would seem we could purchase a small apartment for the same price, but then would have to contend with a mortgage for Mom. If we succeed in having an ADU built, then she would pay nothing monthly.
We've spoken with a few architects regarding this project. Although each have completed numerous projects in San Francisco, each have also shared slightly different information regarding the process by which these structures are to be built. We're to meet on Tuesday with one of the architects who was kind enough to explain rather patiently what this type of work would entail from beginning to end. I look forward to seeing what our upcoming meeting yields!
