Can I legalize an as-built structure into a permitted ADU?
It may be possible to legalize an existing structure (like a guesthouse, a garage, or a basement) into an ADU. Depending on the location and current situation, the process can be quick and straightforward, or complex, lengthy, and expensive.
The existing structure must meet all applicable building codes and zoning regulations. It may be necessary to make structural upgrades or improvements to ensure compliance with contemporary standards.
