West Sacramento Building Permits Guide for Homeowners and Sellers

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team. Information comes from the City of West Sacramento Building Division and Code Enforcement pages; sources are listed at the end.

West Sacramento says a permit is required before constructing, enlarging, altering, repairing or demolishing a building or structure, or installing or altering any equipment. If you are selling a house with an addition, a converted garage or a backyard building, it is worth checking whether the work was permitted.

West Sacramento building permits at a glance

Which projects do not need a West Sacramento permit?

The city’s list of common projects that do not require a building permit includes a single-story detached accessory building used as a tool or storage shed or playhouse with a roof area of 120 square feet or less (contact Planning for setback and height requirements), a retaining wall not over four feet high measured from the bottom of the footing to the top of the wall, changing flooring, carpet, inlaid tile or wood, and painting, papering and similar finish work. If you are unsure, the city asks you to call 916-617-4683.

That list is short on purpose. Additions, structural changes, electrical, plumbing and mechanical work, and habitable conversions generally fall under the permit rule above.

How permits affect selling a house in West Sacramento

Permit issues usually appear when a buyer’s inspector or lender compares the house to the city’s records. Sellers in California generally must disclose known unpermitted work.

On a traditional listing the usual options are to get the work permitted after the fact, give a credit, or lower the price. Each takes time and can move the closing date. If the house has also been cited, read our West Sacramento code enforcement guide.

Work That Needs No Permit Is Still Worth Documenting

The city’s no-permit list is short: a detached single-story shed or playhouse with a roof area of 120 square feet or less, a retaining wall not over four feet tall measured from the bottom of the footing, new flooring or carpet, and painting or papering.

Anything beyond that, including enlarging, altering, repairing or demolishing a building, or installing or altering equipment, calls for a permit.

If you are unsure which side a project falls on, call the Building Division at 916-617-4683 before starting or before listing, and write down who you spoke to and what they said.

Unpermitted Buildings and Code Enforcement

West Sacramento Code Enforcement publishes a handout on unpermitted buildings, and city staff notify owners or residents of violations and the corrective steps needed to comply. Issues that pose an imminent threat get a response within 24 hours.

Garage conversions, enclosed patios and backyard structures are the usual trouble spots when a house changes hands, since a buyer’s inspector or lender may compare the home to city records. Code Enforcement can be reached at 916-617-4925.

California Disclosure Rules for Unpermitted Work

California Civil Code 1102 and following requires most sellers of one-to-four-unit homes to deliver a Transfer Disclosure Statement. It asks about additions, alterations and repairs made without permits, along with known defects and agency notices. Work you finished without a permit belongs on the form, even if it was done by a previous owner and you know about it.

A cash buyer can purchase as-is, so you do not have to permit, repair or tear out the work before closing. If you plan to keep the home and legalize the work, the Building Division is the place to start. This page does not list permit fees or review timelines because the city pages we checked do not state them.

How to sell a house in West Sacramento with unpermitted work or open permits

1. Ask the city what is on file. Call the Building Division at 916-617-4645 about your address.
2. Write down what you know. Who did the work, when, and any receipts or plans.
3. Compare your options. Permit it, sell with a credit, or sell as-is to a cash buyer who prices in the risk.
4. Disclose honestly. A cash offer does not change what you must disclose, but it removes repair and inspection steps.
