Sacramento Zoning and ADU Guide for Homeowners and Sellers

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team. Information comes from the City of Sacramento Planning and Community Development pages; sources are listed at the end.

Every parcel in the City of Sacramento sits in a zoning district that limits what can be built and used on it, and you can look yours up for free with the city’s Land Information Look Up app. For most homeowners the practical questions are whether a backyard unit (an ADU) is allowed, how big it can be, and whether it helps or complicates a sale. The city’s ADU program caps a unit at 1,200 square feet in total.

How do I find my zoning in Sacramento?

Use the city’s Land Information Look Up app. The Community Development Department says it shows the zoning for a specific address, along with the General Plan designation, design review area and council district.

It also shows whether the property is in a historic district or is a contributing resource, which matters for ADUs and exterior changes. If the address is not found, the city asks you to email or call 311.

Zoning is a legal limit on what uses go where, and separate development standards decide how a building must be built. Two houses on the same street can have different zoning, so check the parcel rather than assuming from the neighborhood.

What are the main residential zones in Sacramento?

Most houses fall in the R-1, R-1A, R-1B or R-2 zones. The city’s housing development kit says a recent ordinance expanded the range of housing types allowed by right within these single-unit zones, including R-2.

Under that Missing Middle Housing interim ordinance, an eligible owner in these zones can apply for additional units if the property meets the listed criteria and is not in an excluded area. The rules are detailed, so confirm eligibility with the city before relying on them.

Higher-density residential zones (R-3 through R-5), mixed-use and commercial zones follow separate rules in Title 17 of the Sacramento City Code.

What are the ADU rules in Sacramento?

An accessory dwelling unit is a permanent home on the same lot as the main house. The city says it can be attached, sharing at least one wall with the house, or stand-alone. The city’s ADU program page sets a maximum of 1,200 square feet in combined total and requires every ADU to meet the front yard setback of the property’s zone.

• Types: detached, attached, garage or other conversion, and junior ADU.
• Junior ADU: state law caps it at 500 square feet inside the existing home, with its own entrance.
• Levees: because Sacramento sits between two rivers, the city code restricts building near a levee, so parcels in those areas need extra checking.
• Historic properties: landmark parcels and historic districts have objective design standards for ADUs.

Heights, parking and fees are set by city code and state law and can change. Confirm current figures with Community Development, and use the permit steps in our Sacramento building permits guide.

Does an ADU increase what a Sacramento house sells for?

It can, but only a permitted, finished unit counts fully. Appraisers and lenders give weight to legal living space with a final inspection, and they discount space that was built without permits.

A converted garage or backyard room with no permit history can lower the price or limit buyers, as covered in the permits guide. An unfinished ADU with an open permit is a project, not an asset, and a buyer will price in the cost to complete it.

If the unit is rented, tenant rules apply to the sale too. See our page on how to sell a tenant-occupied house in Sacramento and the city’s Tenant Protection Program.

How to sell a house in Sacramento with an ADU or zoning problem

You can sell a house in Sacramento whether it has a legal ADU, an unpermitted unit, or a use that does not match its zoning. What changes is who carries the risk and how the price is set.

1. Check the zoning and the permit record. Look up the parcel in the Land Information Look Up app and pull the permit history.
2. Sort out what is legal. A permitted ADU with a final inspection is an asset. Anything else is a disclosure item.
3. Compare the routes. Finish or legalize it and list, sell with a price reduction, or sell as-is to a cash buyer.
4. Disclose what you know. California sellers disclose known unpermitted work and zoning issues.

We buy Sacramento houses as they are, including those with converted garages, backyard units and open permits, with no need to fix paperwork first. See how selling as-is in Sacramento works, and what a city citation can mean in our code enforcement guide.
