Unpermitted work can block a HECM when the appraiser or underwriter cannot treat the house as meeting HUD property standards (24 CFR 206.47). Illegal rooms may be valued at zero, or the file may require permits and repairs before endorsement.
Jay Zayer, a Certified Reverse Mortgage Professional licensed in California and Arizona, reads the permit history before anyone pays for a full appraisal, because a garage the city will not legalize wastes counseling money.
Take a Fresno garage that was finished into a bedroom without a permit. That is the file this page is about.
How does the appraiser treat rooms the city never permitted?
The FHA roster appraiser flags what the underwriter cannot ignore. 24 CFR 206.47 says the property must meet the Commissioner’s minimum property standards. An illegal addition can be valued at zero. It can also be called out as work that must be legalized or removed. Cosmetic paint is not the same test. See homes that need repairs for required safety items versus optional remodeling.
A converted garage that is now a bedroom, a kitchen, or a rental unit is the usual hard flag. A small unpermitted patio cover is often a softer one. The appraiser’s report, not a neighbor’s “everyone did it,” decides.
Local code still matters. Fresno will not treat a bedroom without egress the way a permitted bedroom is treated. An accessory dwelling unit (ADU) the city will not recognize is not extra value. It can be a compliance problem that stalls the case number.
Insurance-bindability sits next to HUD’s list. A carrier that will not write a dwelling policy on an illegal conversion will stop the file even if an underwriter might have valued the extra rooms at zero.
Factors at 7.000% expected rate (22 September 2026) generally range from the mid-30s to the low-50s of claim amount. The 2026 maximum claim amount is $1,249,125 (Mortgagee Letter 2025-22). Zeroing an illegal wing can drop the claim amount to the legal house only. Re-run proceeds after the appraisal, not before.
When can you close first and finish legalization from a repair set-aside?
If the city will issue a permit and the work can actually be finished, HUD can allow closing before remaining repairs are done when those remaining repairs do not exceed 15 percent of maximum claim amount. A repair set-aside then holds 150 percent of the estimated cost, plus the allowed administrative fee, from the principal limit.
That set-aside is not a LESA. A LESA holds future taxes and insurance. A repair set-aside holds contractor money for FHA-required work. They can both appear on one file. They are not interchangeable. See the repair article.
Required legalization is a mandatory obligation. It reduces leftover cash the same way a first-mortgage payoff does. Permits do not change the 2.00% initial MIP of claim amount in Mortgagee Letter 2017-12. Origination is still capped at $6,000 under 24 CFR 206.31(a)(1). Those HUD charges stay even after the rooms are legal.
HUD sets completion clocks. If the contractor cannot finish, endorsement or servicing can fail. Do not start California’s seven-day Civil Code 1923.2(k) wait, or pay $125–$175 for counseling, solely to learn the city will not accept the conversion. A permit conversation with the building department is cheaper than a dead 180-day certificate.
Utilities must work. Occupancy is still 24 CFR 206.39. A construction site you cannot live in is both a repair fail and an occupancy fail.
What if the city will not issue a permit for the work that is already built?
Then you cannot set-aside a permit that does not exist. The honest forks are: remove the illegal work, leave it and accept zero value if the remaining legal house still meets standards, or do not originate a HECM on that address.
Here is the Arizona contrast: a 71-year-old in Oro Valley with a casita that was framed without permits. The town will not legalize it as a dwelling. Treating it as extra bedrooms on a HECM worksheet is how files get a surprise appraisal. The legal house may still support a loan. The casita may be valued at zero or called out as a condition. If the illegal unit is the reason the household called, the HECM is the wrong tool.
An ADU that the city will not legalize is the same dead end. Leftover proceeds after closing cannot create a permit. Optional kitchen upgrades after closing are a use-of-proceeds question. They are not a substitute for required legalization.
What can go wrong: the homeowner hides the conversion, the appraiser opens the garage door, and the file restarts. Or the contractor quotes a cheap “as-built” letter that the city will not sign. Or remaining repairs exceed 15 percent of maximum claim amount and someone still promised a close-first escrow.
A follow-up: if the addition is valued at zero, do I still have to tell the insurer it exists? Yes, if it is part of the dwelling the carrier is asked to cover. A zero HUD value is not a secret room. Misrepresenting the structure to the carrier is how claims later fail.
Who should not start counseling on an illegal conversion?
This path does not help a household whose converted garage cannot be permitted. Jay will say to legalize, to remove, or to sell rather than originate a repair race the city has already refused.
It does not help a household whose ADU is the only “extra value” in the plan and the city will not recognize that unit. Zero value on the illegal rooms can leave a principal limit too small for the reason you called.
It does not help someone who wants to finish the illegal work after closing with leftover cash while skipping the appraisal’s required list. Required repairs are closing conditions. Optional upgrades are later draws, subject to 24 CFR 206.25.
I work with multiple lenders. None of them can waive 24 CFR 206.47 because the rooms are already drywalled. Get the permit history, or a written city answer, before you pay for counseling. Unpermitted work is a property-standards gate, not a paperwork courtesy.
