Yes, you can generally build an Accessory Dwelling Unit (ADU) on your property in Sacramento. However, whether or not you can build an ADU on your specific property depends on the zoning of your lot and other regulations. You will need to look up the zoning information for your property and determine if ADUs are allowed.
Under state law, a homeowner in Sacramento may construct up to three dwelling units in addition to the primary dwelling unit. These units may consist of one attached or converted ADU, one detached ADU, and one junior ADU. Additionally, the owners of multi-unit dwellings may convert up to 25% of the portions of the existing multi-unit dwellings that are not used as livable space.
The City of Sacramento’s ADU zoning requirements include considerations for the size, setbacks, and separation of the units. For example, a detached ADU can have a maximum size of 1,200 square feet in total, and must comply with the minimum front yard setback of the property’s zone. A 3-foot minimum interior side and rear yard setbacks are required if the entire ADU is less than 60 feet from the front property line.
ADUs are also allowed within the 30 historic districts in Sacramento. If your property is a historic landmark or within a historic district, your ADU will need to comply with the City’s Historic District Plans and Design Guidelines and the Secretary of the Interior’s Standards. ADUs on landmark properties will need to be reviewed by the Preservation Director.
