Yolo County — Land Use

Land Use under the Yolo County local zoning and planning code, with the controlling citations.

Last reviewed: July 6, 2026

Overview

This page explains what the Yolo County Zoning Ordinance allows to be built and operated in the unincorporated areas of Yolo County—by base zoning district and overlay. It focuses on “what use goes where,” permit levels, and the dimensional rules tied to each district. For a primer on how the County’s zoning system fits together, start at the Yolo County zoning & planning overview and the consolidated Yolo County Zoning page.

Start with your base zone, then check any overlays. The Use Tables show whether a use is Allowed (A), requires Site Plan Review (SP), a Minor or Major Use Permit (UP[m]/UP[M]), or is Not allowed (N) in that zone, as organized by Use Types in § 8-2.904 and § 8-2.905.

“Allowed” uses still must meet development standards (setbacks, height, lot area) and any specific performance standards for that article.
Development standards tables for each district category are in the Yolo County Development Standards section of the ordinance.

How the Ordinance Organizes Land Uses

Use Types and permit levels for each district are listed in the articles for Agricultural (Tables 8-2.304[a–e]), Residential (Table 8-2.504[a]), Commercial (Table 8-2.604), Industrial (Table 8-2.704), and Public/Open Space (Table 8-2.804).
Development requirements—minimum lot size, setbacks, height, FAR/coverage—are in Tables 8-2.305 (Agricultural), 8-2.505 (Residential), 8-2.605 (Commercial), 8-2.705 (Industrial), 8-2.805 (Public/Open Space).
Some uses also have “Specific Use Requirements” within each article (e.g., agriculture in § 8-2.306, commercial in § 8-2.606, public/open space in § 8-2.806).

Special Plan and Overlay Zones (apply in addition to base zoning)

S-P (Specific Plan) and PD (Planned Development): Interim uses are limited; after plan adoption, uses must match the adopted plan/PD ordinance. See permit tables and PD submittal standards.
NH-O (Natural Heritage): Uses must be consistent with the underlying base zone and with the adopted/pending Natural Heritage Plan.
DP-O (Delta Primary Zone): Uses must be consistent with the Delta Protection Commission’s Land Use and Resource Management Plan and the underlying base zone.
SG-O / SGR-O (Cache Creek Mineral Resource Areas): Uses must align with Cache Creek plans; mining is prohibited in/adjoining Putah Creek.
A-O (Airport Overlay): Uses and heights must be consistent with the County Airport CLUP; height governed by Public Utilities Code § 21659.
AD-O (Agricultural District Overlay—Clarksburg): Regulated separately in § 8-2.401; not in the general overlay tables.
Note: Tribal Trust Overlay (TT-O) lands are not under County zoning jurisdiction.
For overlays generally, see Yolo County Overlay Districts.

Specific Use Requirements to Watch

Agriculture: Habitat mitigation projects, animal facilities thresholds, energy facilities, and extraction have detailed SP/UP triggers and performance standards in § 8-2.306; setbacks near levee toes and floodplain findings recur across tables.
Commercial/DMX: Additional DMX design and use mix standards are in § 8-2.606(a); certain large retail uses and drive-throughs require UP.
Public/Open Space: Trip-intensive rural recreation can trigger UP(M) and standards in § 8-2.806.
Energy: Small wind/solar often allowed or SP; POS and P-R prohibit wind systems; wireless and large renewables require UP per the agricultural tables and Article 11 references.

Cross-cutting Notes

Agricultural-residential interface: Minimum setbacks can increase to at least 100 feet where needed to accommodate agricultural spraying adjacent to development.
Flood/levee constraints: Many districts require floodplain findings and restrict development near levee toes; verify early.
Where lacking public utilities, some zones apply a 2.0-acre minimum for new building permits.
Cannabis uses carry separate permit rules under Article 14; check permit level by zone.

Also consider Yolo County Nonconforming Uses if an existing use doesn’t match current zoning, potential variances and exceptions when you cannot meet a standard, and project-related signage rules where a master signage plan is needed.

Checklist

Confirm your base zone and any overlays for the parcel.
Look up the Use Table for your zone to see if the use is A, SP, UP(m), UP(M), or N.
Verify dimensional standards (min lot, setbacks, height, FAR/coverage) for your zone.
Check “Specific Use Requirements” that apply to your use (e.g., ag processing, DMX design, rural recreation).
Screen for floodplain/levee, airport CLUP, Delta/Cache Creek overlays, and agricultural buffers.
Plan for parking, landscaping, and any design review triggers.
If adding an ADU/JADU, follow § 8-2.506(b) and coordinate with California ADU law.
For building/safety, see the California Building Standards Code (covered separately from land use).

Risks & Ambiguities

Issue	Why it matters	What to verify
Agricultural spraying buffers	May force larger setbacks than the base table indicates	Whether the County will require ≥100 ft setback next to active spraying operations
Floodplain/levee proximity	Triggers findings and can constrain siting and elevations	If § 8-2.306 floodplain/levee notes apply to your parcel
Airport CLUP height/use limits	Can restrict heights and certain uses irrespective of base zoning	Whether A-O overlay or CLUP constraints apply; compliance with PUC § 21659
Delta/Cache Creek overlays	Overlay plans override base-zone permissiveness	Consistency with Delta Protection Plan and Cache Creek plans
DMX design controls	Non-compliant massing/mix can stall projects	DMX-specific standards in § 8-2.606(a) and design review expectations
Lack of utilities	Triggers alternate minimum parcel/building criteria	Whether the 2.0-acre minimum for new building permits applies

Plain-English Summary

In unincorporated Yolo County, what you can build depends first on your base zone, then any overlay. Use the zone’s Use Table to see if your use is allowed outright, needs Site Plan Review, or a Use Permit; then meet the zone’s lot size, setback, and height rules. Agriculture-dominant areas have large minimum lots and special buffers; residential zones scale from rural lots to multifamily; commercial/industrial zones set intensity and design controls, especially in Esparto’s DMX.

Frequently asked questions

What can I build on an A-N (Agricultural Intensive) parcel in Yolo County?

Agricultural production is allowed, and many small farm-support activities are permitted or require only Site Plan Review, while larger processing, dairies, or utility-scale renewables typically need Use Permits. Check Table 8-2.304 for your specific use, and meet the A-N development standards in § 8-2.305.

How many homes can I have on a rural residential lot?

In RR-5 and RR-2, one primary dwelling and one second dwelling are generally allowed, subject to setbacks and height limits in § 8-2.505. Parcels without public water/sewer may face a 2-acre minimum for new building permits.

Are ADUs allowed in unincorporated Yolo County?

Yes. ADUs/JADUs are allowed in residential zones per § 8-2.506(b), consistent with state ADU law, and must also meet zone development standards in § 8-2.505.

What are the basics for the R-L (Low Density Residential) zone?

One- and two-unit projects are allowed, ADUs/JADUs are allowed, and small multifamily may be approved with Site Plan Review. Expect about 1.0–9.9 units per acre, a 10-ft front setback (20 ft to garage), and a 35-ft height limit (up to 40 ft with a Use Permit).

Does Esparto’s DMX zone have special rules?

Yes. DMX requires a main-street mixed-use format with tight front setbacks, a minimum building height in certain areas, and limits on predominantly residential projects; see § 8-2.606(a) and the DMX row in the development table.

Can I open a retail store in a Local Commercial (C-L) zone?

Small specialty retail and personal services are typically allowed; larger retail sizes and drive-throughs often require SP or UP. C-L also has a 40,000-sf individual floorplate limit. See Table 8-2.604 and the C-L development table.

What industrial uses are allowed in I-L vs. I-H?

Light manufacturing and warehousing are common in I-L (often SP). I-H accommodates heavier operations but adds setbacks when next to residential. Check Table 8-2.704 and the industrial development standards in § 8-2.705.

Do I need to worry about overlays like the Airport or Delta zones?

Yes. The A-O (Airport Overlay) enforces CLUP consistency and height controls, and the DP-O (Delta) and SG/SGR-O (Cache Creek) overlays require consistency with adopted plans in addition to base zoning. See § 8-2.906.

Are rural recreation uses allowed in open space zones?

They can be, but many require a Use Permit, especially if they generate 100+ vehicle trips/day. See Table 8-2.804 and the rural recreation standards in § 8-2.806.

What if my proposed use isn’t listed for my zone?

If a use isn’t shown as A, SP, or UP in your zone’s table, it’s not permitted in that zone. Confirm with the County or consider whether a different zone/overlay (e.g., PD) or a variance pathway might be appropriate. See § 8-2.904–905. Verify with the jurisdiction.
