Unpermitted Work on a Pleasant Hill Home: What Do You Have to Disclose?

October 11, 2026

Do you have to disclose unpermitted work when you sell a Pleasant Hill home?

Yes, if you know about it. California sellers have to disclose known facts that affect a home's value or desirability, and work done without a required permit is one of them. The state's standard seller disclosure form asks directly whether you are aware of room additions, structural changes, or other alterations or repairs made without the necessary permits. That question applies even if the work was done before you bought the house, and even if you are selling as is.

The good news is that unpermitted work does not have to kill a sale. What hurts sellers is surprise: a buyer who finds it late, through an inspector or a permit records search, and starts wondering what else was not mentioned. When you know what you have and decide how to handle it before you list, it becomes one more thing to price and explain, not a crisis in escrow.

What counts as unpermitted work?

Unpermitted work is any project that needed a building permit and did not get one, or got one that was never finaled by an inspector. That second part surprises people. A permit that was opened and never closed out can show up in city records looking almost the same as no permit at all.

In older Pleasant Hill neighborhoods like Gregory Gardens, Poets Corner, Sherman Acres, and Valhalla, a home may have had several owners and several rounds of updates. Some of the projects that can turn up without permits:

  • Garage conversions into a family room, office, or bedroom
  • Enclosed patios turned into sunrooms or extra living space
  • Added bathrooms or a laundry room moved inside
  • Kitchen remodels that moved plumbing, gas lines, or walls
  • Electrical panel upgrades and new circuits
  • Water heater and furnace replacements
  • Window replacements that changed the size of an opening
  • Backyard structures like a converted shed or a detached studio

Cosmetic work like paint, flooring, and new cabinets in the same layout generally does not need a permit. The line between cosmetic and permitted work depends on the city's rules, which is why the next step matters.

How do you find out what was permitted on your home?

Start with the city. Inside city limits, the City of Pleasant Hill's building division handles permits and keeps permit records by address. You can request the permit history for your home and compare it against what is actually there. If your address sits in an unincorporated pocket near Pleasant Hill, Contra Costa County handles permits instead, so confirm which office has your records before you ask.

Then compare three things:

  1. The permit history. What was permitted, and was each permit finaled?
  2. The county assessor's description. It lists the recorded square footage and room counts.
  3. The house as it stands. Walk it with a notepad. Count bedrooms, bathrooms, and living space.

When those three do not match, you have found the gap a buyer's agent will find too. A garage that is now a bedroom, a square footage figure well below what you measure, or a bathroom count that is one short are all signals worth chasing down.

A pre-listing inspection can help here as well. An inspector will not tell you whether something was permitted, but they will flag work that looks like it was done without one, and that gives you a list to check against the city's records.

What are your options once you find it?

You have four realistic paths. None of them is right for every home, and the best one depends on what the work is, how much it adds, and how much time you have before you want to list.

Option 1: Disclose it and sell as is

You disclose the work clearly, price the home with it in mind, and let buyers decide. This is the fastest path and can be the right one for smaller items like a water heater swap or an older patio enclosure.

The tradeoff is that some buyers will discount the space, and some lenders and appraisers will treat unpermitted living area differently than permitted area. If the unpermitted part is a big share of what makes the home appealing, selling as is may cost you more than legalizing it would.

Option 2: Legalize it before you list

You apply for a permit for work that already exists. This is sometimes called an as-built or retroactive permit. The city reviews plans, an inspector looks at the work, and you may need to open walls or make corrections so the work meets current code before it can be finaled.

This path can take real time, and the scope can grow once walls are open. It makes the most sense when the unpermitted work adds meaningful living space, like a converted garage or a family room addition, and when you have runway before your target list date.

Option 3: Remove or restore it

Sometimes the cleanest answer is to undo the work. A garage conversion that would be expensive to legalize might be returned to a garage. A shed with wiring that was never inspected might lose the wiring.

This trades the extra space for certainty. It is worth comparing against Option 2 with real bids in hand, not guesses.

Option 4: Disclose it and offer a credit

You disclose the work, and during negotiations you offer a credit or price adjustment so the buyer can handle it after closing. This keeps your timeline intact while giving the buyer a clear way to deal with it. It works best when the buyer's lender is comfortable with the property as it stands, so talk it through with the buyer's agent early.

What does unpermitted work actually cost you?

The cost shows up in a few places, and the biggest ones are about value and time rather than a single bill.

Value. An appraiser may not count unpermitted space the same way as permitted space. A converted garage might be valued as a garage, not a bedroom. That can lower the appraised value compared to what the house looks like in person, which matters if your buyer is financing.

Buyer pool. Some buyers will pass on a home with open permit questions. Others will stay but ask for more in negotiations. A smaller pool of interested buyers can mean less room to hold your price.

Escrow risk. If the issue comes out late, through the buyer's inspection or their own records search, it can lead to a repair request, a renegotiation, or a buyer who cancels within their contingency period. If you have not read our explanation of what contingent means for California buyers, it is worth a few minutes, because this is the window where surprises do the most damage.

Legalization costs. If you choose to permit the work, there are plan and permit fees, inspection time, and any corrections the inspector requires. These vary widely by project, so get bids from licensed contractors before you decide.

Legal exposure. The quietest cost is the one that shows up after closing. A buyer who later learns about known unpermitted work that was not disclosed may have a claim against the seller. Disclosing up front is how you protect yourself from that.

What mistakes do sellers make with unpermitted work?

Hoping nobody notices. Buyer's agents and inspectors look for exactly this. Square footage that does not match public records is one of the first things a careful buyer checks. Hoping is not a plan.

Calling it a bedroom in the listing. If a room was created without a permit, describing it as a permitted bedroom invites trouble. Describe the space accurately and let the photos show what it is.

Assuming as is means no disclosure. In California, selling as is limits what repairs you agree to make. It does not remove your duty to disclose what you know.

Starting a permit the week before listing. Legalizing work takes planning and inspections. Starting late can leave you with an open permit in the middle of your sale, which is its own disclosure issue.

Skipping the conversation with a professional. Disclosure questions can carry legal weight. Talk with your agent about the facts, and with a real estate attorney if you are unsure what you are required to say.

What could this look like in a Pleasant Hill sale?

Here is an illustrative example, not a real client.

A couple in Gregory Gardens is getting ready to sell the home they bought years ago. The previous owner converted the attached garage into a family room. It is bright, has its own heater, and is where their kids grew up watching movies. They have always thought of the house as three bedrooms plus a big family room.

When they pull the permit history, there is no permit for the conversion. The county records still show a two-car garage and a smaller square footage than they measure.

They sit down and look at their options together:

  • Legalize it. They get a bid and learn the conversion would need upgrades to meet current code. It is doable, but it would push their listing back by months.
  • Restore the garage. Possible, but the family room is a big part of the home's appeal.
  • Disclose and sell as is, with pricing built for it. They describe the room accurately as a converted garage without permits, price the home based on its permitted square footage and condition, and prepare a short summary for buyers.

They choose the third path. Buyers see the room, understand exactly what it is, and can make their own plan. There is no surprise in escrow because there was nothing left to discover.

That is the goal in every version of this story. Not perfection, just no surprises.

How Jessica helps sellers handle permit questions

Unpermitted work is one of those topics that makes sellers feel like they did something wrong, even when the work was done by someone else long before they moved in. That feeling can lead to avoidance, and avoidance is what turns a manageable issue into an escrow problem.

Jessica's approach is to slow down and get the facts on the table first: what was done, what the records show, and what each option would mean for your price, your timeline, and your peace of mind. Then she lays out the paths side by side so you can choose with the full picture in front of you.

Frequently asked questions

Do I have to disclose unpermitted work done by a previous owner?

If you know about it, yes. California's disclosure duty covers known facts about the property, not just work you did yourself. If you are unsure whether something was permitted, check the city's records before you fill out your disclosures.

Can I sell a house in Pleasant Hill with unpermitted work?

Yes. A home with unpermitted work can still sell. The key is disclosing it, pricing for it, and understanding how the buyer's lender and appraiser may treat the space.

Will the city make me fix it if I request my permit history?

Requesting records is a normal part of preparing to sell. What happens after you apply to legalize work depends on the project, so ask the city's building division about the process before you file anything.

Does unpermitted space count toward square footage?

It depends on who is counting. Appraisers and public records may not count unpermitted living area the same way you do. Describe the home accurately and avoid advertising unpermitted space as if it were permitted.

Should I get a permit before listing or just offer a credit?

It depends on how much the work adds to the home and how much time you have. Larger additions may justify legalizing. Smaller items may be handled with clear disclosure and pricing. Get real bids and compare the options side by side.

The bottom line

Unpermitted work is a fact to manage, not a secret to keep. Find out what you have, compare your options with real numbers from licensed contractors, disclose what you know, and price the home for what it is. Sellers who do that walk into escrow knowing what is coming.
