A companion unit is a secondary living unit often referred to as a granny unit, an in-law unit or renters unit. These units are permitted on single-family properties located in the R1 zoning district. These units can be detached from the primary house or attached to the primary house with no shared interior doors. For more information on companion unit requirements and allowances, visit the zoning page.
Prior to building permit issuance, a one-time Park Land Dedication In-Lieu fee is required for new living units, including companion units. This fee is collected by the Public Works Department to purchase land to create new neighborhood parks and to renovate or improve existing parks and park facilities. Staff encourages you to get an estimate of the fee from the Public Works Department prior to submitting for building permits by contacting them at (650) 903-6311.
