In my years helping local service businesses connect with homeowners just like you with established single-family homes and, I've seen this question come up time and again. Get ADU Cost Estimate The short answer is almost always yes for most properties, thanks to California's streamlined 2025 laws. Accessory Dwelling Units (ADUs) are secondary, self-contained homes on your existing lot, complete with kitchen, bathroom, and entrance. They're perfect for multigenerational living, and state rules have removed many barriers to make them easier to add. Whether in Elk Grove, Roseville, Folsom, or secondary spots like Vacaville or Rocklin, eligibility boils down to a few key checks. Let's break it down honestly so you can decide if this fits your plans without the usual confusion over permits or rules.

Basic ADU Eligibility Requirements in Sacramento Area

The good news in 2025 is that most single-family properties qualify for an ADU under California Government Code Section 65852.2. You need an existing or proposed primary single-family home on the lot, that's the main requirement. There's no strict minimum lot size in many cases, and properties of any size can often add an ADU.

Key eligibility points:

• Primary Residence Required ,  Your property must have a single-family home (or be planned for one).

• Zoning ,  Residential single-family zones generally allow ADUs; most common zones in Sacramento County and the City of Sacramento qualify.

• No Owner Occupancy Mandate ,  For ADUs permitted in 2025, you don't have to live on the property (this rule was extended indefinitely).

• JADUs Included ,  Junior ADUs (up to 500 sq ft inside the main home) are also allowed in most cases, adding flexibility for smaller family needs.

If your lot meets these basics, you're likely good to go, many families I've worked with were surprised how straightforward it is once they checked.

Zoning Rules and Lot Requirements for ADUs

Zoning is where a lot of homeowners get stuck, but Sacramento's rules follow state standards with some local tweaks. In unincorporated Sacramento County and the City of Sacramento, ADUs are permitted by right on eligible lots.

Common zoning and lot standards (2025):

• Setbacks ,  4 feet minimum for side and rear yards in most cases; conversions of existing structures (like garages) often exempt from new setbacks.

• Height Limits ,  Up to 16 feet for detached ADUs on single-family lots; up to 25 feet if attached.

• Lot Coverage & Size ,  No strict minimum lot size for ADUs; rules focus on setbacks and height rather than total area.

• Parking ,  Often no additional parking required for the ADU if near transit; one space per bedroom max in some zones. Get ADU Cost Estimate

For example, if your property is in a standard R-1 zone in the City of Sacramento, ADUs must follow the zone's height (often 35 feet max) but benefit from reduced side/rear setbacks. County areas have similar flexibility, with pre-approved plans available to simplify compliance. Start My ADU Plan

ADU Eligibility for Different Types in Sacramento

Different ADU types have slightly different rules, but all are designed to be accessible:

• Detached ADUs ,  Most flexible for backyard placement; max 1,200 sq ft in many zones.

• Attached ADUs ,  Good for home extensions; often higher height allowance (up to 25 feet).

• Garage Conversion ADUs ,  Exempt from new setbacks if converting existing structure, popular for quick family or rental additions.

• Tiny Homes as ADUs ,  Allowed when built permanently on your lot with foundation and utilities.

Most single-family lots can add one full ADU and one JADU. Multi-family properties have even more options, but single-family is the focus for most homeowners. Get ADU Cost Estimate

• Certain overlays or special zones (like some EA-2 zones in the City, limiting to one ADU). Start My ADU Plan
