Yes — you can sell a house with unpermitted work in California. Unpermitted work does not void your ability to sell, but it does affect your options and your buyer pool. Traditional buyers using bank financing will run into problems — lenders won’t fund a home with known unpermitted work or code violations. Your options are to disclose and sell as-is, pursue retroactive permits, redo the work correctly, or sell directly to a cash buyer who specializes in distressed properties. Quick Home Offers® has been purchasing homes with unpermitted work throughout California since 2013.

What Counts as Unpermitted Work In California?
Unpermitted work is any modification to a home’s structure, electrical, plumbing, or mechanical systems that was completed without a building permit or without passing required inspections. Common examples include garage conversions, room additions, ADUs, electrical panel upgrades, plumbing reroutes, and HVAC installations. In California, building permits are required any time work affects the structure or essential systems of a home — regardless of who did the work or when it was done.
Your Options for Selling a House With Unpermitted Work in California
Homeowners with unpermitted work have four realistic paths. The right choice depends on your situation, timeline, severity of the work, if you’re currently being fined by the city or county, and how much you’re willing to spend before selling.
Option 1: Disclose and Sell As-Is
California law requires sellers to disclose known unpermitted work to ALL buyers, regardless if they are cash buyers or not. Disclosing does not prevent the sale, but it will limit your buyer pool depending on the work done. If it’s a simple item such as changing an outlet or breaker, many buyers may choose to move forward. If it’s something more substantial, like room additions, roofs, electrical panels, etc, it can pose an issue for lenders and prospective buyers. If you have done substantial work like a bathroom addition or remodel, room addition, garage conversion, etc you may have restricted your buyer pool to just cash buyers who are willing to take on the permitting process themselves.
Option 2: Pursue Retroactive Permits
In some cases, the unpermitted work can be permitted after the fact. You will need to make sure the work complies with the current building code. If the work was done to code at the time, this may not matter, and you may need to do additional work to bring it up to today’s building code. Contact the local building department to see what’s involved. This route works best when the unpermitted work is simple, like a roof, deck, fence, or very simple addition. This may not be a great path if it’s more involved work like structural, electrical, plumbing systems, etc., that will require opening walls or the subfloor for inspection.
Option 3: Redo the Work With Proper Permits
If retroactive permits are not possible, your next option is to have the work completely redone correctly by a licensed contractor who will pull permits, redo the work, and call for inspections. This is by far the most expensive path, but it adds the most value to your home or property. Make certain to get multiple bids, and compare the cost to cure vs the value added. It also helps to compare to your other options, such as selling as-is.
Option 4: Sell Directly to a Cash Buyer
If you don’t want to spend time or money on permits or repairs, selling directly to a cash buyer is your fastest and most straightforward option. Cash buyers like Quick Home Offers® purchase homes with unpermitted work as-is throughout California — no repairs required, no permits required, no agent commissions. The offer will reflect the property’s current condition, but when you factor in what you’re not spending on repairs, permits, and carrying costs, the net difference is often smaller than expected.

Frequently Asked Questions — Unpermitted Work in California
Q: Do I have to disclose unpermitted work when selling in California?
A: Yes. California law requires sellers to disclose known material facts that affect the value or habitability of the property. Unpermitted work is a material fact and must be disclosed to any prospective buyer, regardless of how you sell. Failure to disclose creates legal liability that follows you after the sale closes.
Q: Can a house with unpermitted get a mortgage?
A: Generally, no. Conventional lenders — including FHA and VA — will not fund a home with known unpermitted work or code violations. This significantly limits your buyer pool to cash buyers or buyers willing to take on the permitting process themselves before closing.
Q: What happens if I sell a house without disclosing unpermitted work?
A: Failing to disclose known unpermitted work in CA exposes you to serious legal liability, including lawsuits, rescission of the sale, and damages. California courts have consistently held the parties responsible for non-disclosure of material defects. Always disclose everything in writing to cover yourself.
Q: Can unpermitted work be permitted after the fact in California?
A: Sometimes. If the work was done correctly and meets the current building code, a local building inspector may approve it retroactively. The process, cost, and timeline vary significantly by city and county. Contact your local building department to understand what is involved, the timeline, and estimated permit costs before assuming retroactive permits are possible.
Q: How does unpermitted work affect the value of my home?
A: Unpermitted work reduces your effective buyer pool and typically results in lower offers from buyers who factor in the cost and risk of resolving the permits. The discount varies depending on the type and extent of the unpermitted work. An unpermitted garage conversion carries more risk than an unpermitted patio cover or deck.
