Second Unit Ordinance
The Town encourages homeowners to consider creating a second living unit on their single family residential zoned property. Second units can often be approved administratively and, if that is not possible, there is the opportunity to gain approval by obtaining a use permit and/or a variance. Staff is happy to discuss your plans with you.
The second unit is in Title 10, Chapter 6 of the San Anselmo Municipal Code.
