Most LA buyers expect title insurance and a lender’s appraisal to catch any significant problem with a property before close. For unpermitted construction, neither does what buyers expect. Title insurance generally does not cover unpermitted work. Lenders use the appraisal to detect it but only catch a fraction of cases. The buyer absorbs the rest.

This is the practical explainer: how title insurance treats unpermitted work, what triggers a lender to reject or reduce a loan because of it, and what the seller, buyer, and lender each actually owe.

Title insurance: what it covers and what it does not

A standard title insurance policy (whether owner’s policy or lender’s policy) insures against defects in title: liens, unpaid taxes, fraudulent deeds, missing heirs, easements that did not get disclosed, boundary disputes. It does not insure against building code violations, including unpermitted construction.

This is in the standard exclusions of the CLTA (California Land Title Association) policy. Section 1, item 4 typically reads (paraphrased): “Any law, ordinance, or governmental regulation restricting, regulating, prohibiting, or relating to the construction, use, occupancy, or improvement of the land.” Building codes fit squarely within that exclusion.

The practical effect: if a Notice of Substandard Property or a recorded Order to Comply exists on the parcel at the time of close, the title policy may or may not flag it depending on how the city recorded the notice. If the city has filed a Notice of Substandard Property as a recorded document, title insurance will see it as a cloud on title and the title company will refuse to insure unless it is cleared. If the city has only issued an unrecorded Order to Comply, title insurance does not see it, does not flag it, and the buyer inherits the violation at close.

When title insurance does help

Two situations where title can still help:

Recorded Notice of Substandard Property. If LADBS or LA County Code Enforcement has formally recorded a notice against the property, it appears in the title commitment. The buyer sees it before close and can require the seller to clear it. (See our list of common code violations for what triggers a recorded notice.)

Mechanic’s liens from unpermitted work. If a contractor did unpermitted work and was not paid, they may have filed a mechanic’s lien. The lien shows up in title and must be cleared at close. The underlying unpermitted work itself is not insured against, but the financial dispute around it is.

Beyond these two, title insurance does not protect against the cost of legalizing or removing unpermitted construction.

How lenders detect unpermitted work

Lenders are more aggressive than title insurance about unpermitted work, but their tools are imperfect. The three main detection channels:

1. The appraisal. Every lender orders an appraisal. The appraiser physically measures the property, draws a floor plan, and compares it to the county assessor’s official record. If the measured square footage exceeds the recorded square footage, the appraiser is required to flag it. For FHA, VA, and most conventional loans, unpermitted square footage is then excluded from the appraised value. (Details in our appraisal guide.)

2. The lender’s review of permit records. Some lenders (especially for jumbo, FHA, and VA loans) pull the parcel’s permit history during underwriting and cross-check it against the appraisal floor plan. If a kitchen, bathroom, or bedroom appears on the appraisal but no permit exists, the lender may require legalization, a price reduction, or escrow holdback.

3. The HOA or condo association questionnaire (if applicable). For condos and townhomes, the HOA fills out a lender questionnaire that includes “any known unpermitted construction.” If the HOA is aware of unpermitted work on the unit, it has to disclose it.

What happens when the lender flags unpermitted work

The lender has three options, listed by frequency:

1. Exclude the unpermitted area from the appraised value. The most common outcome. A 400 sq ft unpermitted garage conversion that would add $200,000 in legal living space adds $0 (or sometimes a small “below-grade” partial credit). The loan amount drops accordingly. Buyer must come with more cash to close.
2. Require legalization before funding. Less common, but happens with FHA and VA loans where the unpermitted work creates a safety or habitability issue. Seller must pull a retroactive permit and pass inspection before close. Slows escrow by 6 to 12 weeks.
3. Reject the loan entirely. Rare but not unheard of. Most common with FHA on properties where the unpermitted work creates major code violations (no egress windows in bedrooms, no smoke detectors, illegal occupancy).

What this looks like in real escrow

A typical pattern we see in LA: buyer is approved for a $900,000 loan on a $1.1M house. Appraisal comes in. Appraiser flags an unpermitted 350 sq ft addition (a finished sunroom that was added in 2002 by the prior owner). The lender’s underwriter excludes the 350 sq ft from the appraised value. Appraised value drops from $1.1M to $980,000. Loan-to-value drops with it. Buyer can:

• Bring an extra $60,000 to close (most common)
• Renegotiate the price with the seller (works if seller has flexibility)
• Require seller to legalize before close (slows the deal)
• Walk away (if inside inspection or appraisal contingency)

Owner’s title policy vs lender’s title policy

Buyers sometimes assume the owner’s title policy is broader than the lender’s. For unpermitted work specifically, both policies have the same exclusion. The owner’s policy protects you against title defects after close (someone showing up with a competing claim, a recording error, etc.) but does not protect against code violations the city issues after close.

The “extended” or “ALTA” owner’s title policy (more expensive, more comprehensive) gives broader coverage on some title issues but still excludes building code violations.

The single best protection: do your records homework

Because title insurance is not going to protect you and the lender catches only a fraction of unpermitted work, the buyer’s best protection is to do the records homework yourself before the inspection contingency expires. Two free tools:

• LADBS permit search: every permit ever pulled on the parcel
• LADBS violations search: any open code-enforcement actions

If anything looks off, get a pre-purchase compliance audit before you waive contingencies. Cost: a few hundred to a few thousand dollars. Savings if it finds something: routinely $20,000 to $100,000.

For sellers: disclose now, fight later

If you are selling a property with known unpermitted work, the California TDS form requires disclosure. The temptation is to omit it and hope no one catches it. Don’t. Discovery during escrow leads to renegotiation. Discovery after close leads to lawsuits with damages that can include the cost of legalization, the cost of removal, lost market value, and attorney fees.

The cleaner path: legalize before listing, or price the unpermitted work into the asking price and disclose. See our guide on selling a house with unpermitted construction.

The bottom line

Title insurance does not protect against unpermitted construction. Lenders detect it sometimes but not always. The buyer is the one who pays the legalization or removal cost. The right protection is to find unpermitted work yourself, with the public records, before you waive contingencies. The right protection for sellers is to legalize or disclose before you list.

If you are mid-escrow and just discovered unpermitted work on your future property, talk to us before you finalize anything with the lender. We can quote the cost of legalization in 24 to 48 hours so you have a number to work with at the negotiation table.
