Fullerton building permits at a glance

How do I check permits on a Fullerton property?

The city’s Permits and Licenses page lets you check the status of a building permit or case, a planning case and a code enforcement complaint. For older records on an address, call Building and Safety at (714) 738-6541 and ask what is on file. If an addition, garage conversion or remodel has no permit, treat it as unpermitted work.

Why does unpermitted work matter in Fullerton?

Fullerton’s Code Enforcement Division enforces rules about construction without appropriate building permits. See our Fullerton code enforcement guide.

How permits affect selling a house in Fullerton

In California, sellers generally have to disclose known problems, including work you know was done without a permit. On a traditional sale, buyers often ask for a closed-out permit, repairs or a price cut. A cash buyer can purchase the house with the permit problem unresolved and price the risk into the offer.

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

1. Check the city record. Look up the address and call Building and Safety.
2. List what you know. Who did the work, when, and whether you have receipts or plans.
3. Compare options. Finish the permit, sell with a price credit, or sell as-is to a cash buyer.
4. Disclose honestly. A cash offer does not change what you must disclose.

Why the city’s plan rules matter to a seller

Fullerton says plans must be prepared by a qualified person, and that most project types need a California licensed architect or engineer; city staff do not prepare plans. It also warns that incomplete or non-compliant plans can delay the permit and add plan review fees.

Read that as a hint about what past work looks like. Where a past owner skipped the plan requirement, the project may have stalled, or the work was built without drawings that match what the city expects. If you hold plans from a past remodel, keep them with your disclosure documents.

The city says it is working under the 2025 California Building Standards Codes, which is the baseline for new permit applications. Older work was permitted under the codes of its own time, so a permit from decades ago is not a defect on its own. What a buyer looks for is a record that shows the work was inspected and finaled.

Over-the-counter review and what it says about small jobs

The city offers over-the-counter review for projects needing about 30 minutes or less, such as residential patio covers, small kitchen or bathroom remodels, commercial signs and free-standing non-retaining block walls, although it may require a detailed review depending on scope.

If your house has a patio cover, a block wall or a kitchen or bath remodel, those are exactly the kinds of improvements that should have a permit record. They are small and common, which also means they are among the first things a buyer’s inspector asks about.

One page for permits, planning cases and code complaints

The city’s Permits and Licenses page lets you check the status of a building permit or case, a planning case and a code enforcement complaint. That makes it a one-stop check for a seller. Run your address through it before you list, and note anything that shows as open. For anything older or unclear, call Building and Safety at (714) 738-6541.

A Fullerton seller’s permit checklist

1. List improvements by type: patio covers, block walls, kitchen and bath work, additions, conversions.
2. Check the Permits and Licenses page for permits, planning cases and code complaints on the address.
3. Call (714) 738-6541 for anything the page does not show.
4. Gather plans and receipts for finished work.
5. Decide on a path before listing: close out, credit or sell as-is. Our California as-is and unpermitted work guide explains disclosure, and our Fullerton code enforcement guide covers what happens if a case is open.
6. Check the cost side in the seller closing costs guide.

Three Fullerton situations and how each plays out

A patio cover built years ago. This is one of the over-the-counter project types the city names. If no permit exists, ask Building and Safety what legalizing a patio cover would involve before you decide how to sell.

A kitchen or bath remodel by a prior owner. The city names small remodels among quick reviews, so a record should exist. If it does not, a buyer’s lender may notice.

A garage turned into living space. This is larger than an over-the-counter project and may involve plans from a licensed architect or engineer. Ask the city early, because it drives both cost and timing.

Planning the timeline around permit work

A project that needs plans can take much longer than a counter review, and the city warns incomplete plans can delay a permit and add fees. If your closing is near, compare the cost of delay against a cash buyer’s discount for taking the house as it is.
