An unpermitted addition does not automatically fail reverse mortgage eligibility. Jay Zayer, CRMP, is a reverse mortgage specialist at reversemortgage.coach. An unpermitted-addition HECM still has to meet FHA property standards under 24 CFR 206.47. The appraiser, not a floor-plan sketch, decides whether the extra rooms can be valued, ignored, or required to be legalized or removed.
Suppose a borrower named Nico, 66, in Escondido enclosed a patio years ago without a permit and now occupies the house as a principal residence. That enclosure may be a repair-list item, a value haircut, or a stop if the city will not legalize it and the appraiser will not support the house as habitable without it. The sibling unpermitted work page is the appraiser-and-escrow sequence. This page is the eligibility verdict on the addition itself.
A HECM is FHA-insured. It is not a permit-amnesty program and it is not a government benefit.
Does an unpermitted addition automatically fail HECM property standards?
No. 24 CFR 206.47 points the mortgagee at HUD property standards. An extra room the city never permitted can be treated as non-living space, as deferred maintenance, or as a required repair. An uninhabitable conversion can also fail occupancy under 24 CFR 206.39. Those are different fails. Families mix them.
Age is still 62 under 24 CFR 206.33. Counseling is still 24 CFR 206.41. A garage conversion does not waive those tests.
Model leftover cash after required repairs. Repair-adjusted capacity still lands in the mid-30s to low-50s percent of appraised value, depending on age and expected rate. Illegal square footage does not invent a higher factor.
An unpermitted-addition file still pays initial MIP of 2.00% of maximum claim amount under Mortgagee Letter 2017-12. The 2026 cap is $1,249,125 (Mortgagee Letter 2025-22). Origination is still capped at $6,000 under 24 CFR 206.31. Annual MIP still accrues at 0.50% of outstanding balance. An adjustable HECM still uses 1-month CMT plus lender margin.
How is an addition different from a kitchen remodel the city never saw?
An addition changes the building’s footprint or habitable rooms. A kitchen remodel inside existing walls is usually a condition and permit question, not a new dwelling unit. Both can show up on the appraiser’s list. Only the addition is how people try to bank illegal square footage as if it were already on the assessor’s sketch.
If remaining required repairs exceed 15 percent of claim amount, complete them before closing or do not originate. On a $400,000 claim amount, the 15 percent unpermitted-repair gate is $60,000 of remaining required work. Fifteen percent of a house already at the 2026 $1,249,125 cap is a much larger unpermitted-repair dollar gate. The unpermitted-repair gate is a percentage of maximum claim amount, not a kitchen-table guess.
A LESA, if residual income requires one, is still origination-only. It does not pull a permit. It holds future taxes and insurance.
When must legalization finish before closing versus a repair escrow?
When the house is not occupiable without the work, or when remaining required repairs exceed HUD’s escrow gate, finish first. When the appraiser lists limited items that fit the gate, a repair set-aside can be a path. A certificate that expires in a permit queue is a wasted session. Counseling still costs $125–$175. The HUD certificate lasts 180 days. California Civil Code 1923.2(k) still adds seven days after counseling.
A second geography: a 78-year-old in Casa Grande with a converted carport the county will not legalize. Arizona permitting is local. FHA occupancy and property standards are federal. If the unit is the only legal bedroom and the conversion fails, the file fails.
See home needs repairs for the broader repair list. See major repairs if the dollar gate is the live question.
Unpermitted-addition files that are complete still average about 30 days to close. That is not a guarantee. A permit that never issues is how that average stretches.
Who should not count illegal square footage in the “as-is” value they want?
Do not. Type the value the FHA appraiser can support. Do not book counseling to “make HUD count the extra rooms.” HUD will not.
This path does not help a household whose only proceeds story is illegal square footage, or whose remaining repairs exceed 15 percent of claim amount with no cash to finish them. Paying initial MIP of 2.00% of claim amount for illegal square footage is a poor trade. I will say to legalize, to remove, to sell, or to wait.
What can go wrong: counseling is completed on a floor plan the city never approved, then the appraiser will not include the rooms. Or someone starts demolition the week of the inspection. Or an uninhabitable add-on is treated as a cosmetic item.
If heirs later keep an unpermitted-addition HECM house, they still repay the outstanding balance under 24 CFR 206.125(a)(2)(i). An unpermitted room does not rewrite that subsection.
I will originate when the appraiser can support an eligible dwelling. I will turn away a floor-plan slogan the city never stamped.
