The unpermitted work nobody thought to file for
Long Island housing stock has been extended, finished and converted for generations, and permits were not always the habit. A good share of the square footage people live in today was added quietly over a few weekends.
That is why this comes up so often at the closing table. The house you have been living in and the house on file at the town are two different houses, and the gap between them is what unpermitted work actually means.

Who we call when the permit file is complicated
This is a paperwork problem more than a building problem, and paperwork problems reward people who have done them before.
An expeditor knows what the department wants and in what order. An architect can draw the as-built set. A surveyor can show where the structure actually sits. We have used all three across Nassau and Suffolk for years and we are glad to put you in touch, even if you decide to keep the Elmont house and see the permit process through yourself.
What this looks like in Elmont specifically
Elmont is roughly 37,296 people in Nassau County, ZIP 11003, and the housing stock is mostly cape cod, ranch, multi-family. Around Belmont Park and UBS Arena, most of it is old enough that the mechanicals are on their second or third life. The Elmont-UBS Arena stop pulls buyers who commute, which supports the good houses and does very little for the ones that need a roof. We know which of these streets take water, where the older systems fail first, and what the Elmont Union Free School District does to a resale price.
The median has slipped 1.35% year over year as of 2026-05. It is a small move, but a softening market punishes the houses that need work first - buyers with choices do not choose the project. A $725,000 median puts Elmont in the band where buyers are stretching to afford the house and have nothing left for the roof. That is precisely the buyer who walks away from a property needing work, and it is why condition matters more here than the price alone suggests. The median house goes under contract in about 43 days, which is not slow - but it describes houses that were already showable on day one.
What a municipal search turns up about unpermitted work on an Elmont house
The awkward part is how late it surfaces. Everything feels fine until a search comes back and the deck, the basement or the extra bathroom is not on file anywhere and no permit was ever pulled.
By then there is a signed contract, a mortgage commitment with conditions attached, and a buyer who has started packing. Renegotiation follows, then often a collapse, and an Elmont house goes back on the market with more days on it and a story attached.
What your Elmont building department wants before it issues a permit
Getting work approved after the fact is possible sometimes and impossible other times, and which one you are in turns on details nobody can judge from the outside. Setbacks, lot coverage, ceiling heights, egress, how current code differs from the code in force when it was built.
Your town's building department decides what can be permitted now, and an expeditor will know how that department tends to handle it. What we can tell you is that the process runs slower than a sale does, which is the practical problem.
What the two paths cost in Elmont
These are the two routes open to you with a house with unpermitted work, priced against what Elmont houses actually sell for.
Work it against Elmont's own numbers. The median sale here is $725,000. A 5% commission on that is $36,250, and seller closing costs of about 2% add roughly $14,500. Those are costs we can cover on our side. That is $50,750 gone before anyone counts the repairs it took to get the house listable.
There are two waits in a listed sale and people usually only count the first. In Elmont the median house takes about 43 days to go from listed to a signed contract. Then it waits again, typically 45 to 60 days, while the buyer's lender orders an appraisal and underwrites the loan. Call it 88 to 103 days from sign to keys, assuming nothing goes wrong.
The part worth understanding is what a signed contract actually guarantees, which is less than most sellers assume. A retail buyer with a mortgage contingency can walk away right up to the end. If they do not qualify, if the appraisal comes in under the price, if they change their mind and let the financing lapse. A share of deals die exactly there, after months of waiting, and the house goes back on the market with time on it. We are not borrowing anything, so there is no lender to satisfy, no appraisal to come in low and no contingency to exercise.
| Listing with an agent | Selling to us | |
|---|---|---|
| Sale price | $725,000 (Elmont median) | Our written offer |
| Commission | −$36,250 | None |
| Seller closing costs | −$14,500 | We can cover them |
| Repairs before listing | Out of pocket | None |
| Cleanout | Yours | Ours |
| Showings | Until it sells | One visit |
| Listed to signed contract | 43 days (Elmont median, once listable) | 24 hours to a written offer |
| Contract to closing | 45 to 60 days (waiting on the buyer's lender) | A date you choose |
| Total wait | 88 to 103 days if nothing falls through | Yours to set |
| Can the buyer walk? | Yes (mortgage contingency runs to the end) | No financing to fall through |
| Before repairs and carrying | $674,250 | The number we put in writing |
The agent column uses a 5% commission and about 2% of seller closing costs, which are typical rather than fixed. It leaves out repairs and holding costs because no two houses are alike there. Where a house is in good condition, listing with a capable agent can beat our number, and we will be upfront if that is the case.
Legalizing the unpermitted work first, or selling as-is
The comparison worth making is not our offer against an asking price. It is money in hand on a date you choose, set against a listed number minus commission, minus whatever the permit process costs, minus the concessions a buyer asks for once the file comes back, and minus several months of carrying an Elmont house.
We will lay ours out in writing so it can be compared honestly. If the listing wins on that arithmetic, take the listing.
How we arrive at a number on a house with unpermitted work
For a house with unpermitted work, the starting point is the price once it is fully repaired. We subtract what the repairs cost and then a margin for being wrong about the price or the repairs. No algorithm and no trade secret: that is how the number is built.
- What it is worth repaired. Not the Elmont median of $725,000 on its own, but what houses like yours on your street actually closed at recently.
- What the work costs. Roof, boiler, electric, the kitchen and bath. In Elmont the stock is largely cape cod and ranch, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Elmont house goes under contract in about 43 days once it is showable, then waits 45 to 60 days more on the buyer's lender. Ours has to get to showable first, and we carry taxes and insurance across the whole of it.
- What we are wrong about. Every renovation turns up something nobody could see on the walk-through. We build that risk into the price, and it explains a good part of why cash offers come in below retail.
Where our margin actually comes from
Plainly, because buyers are often vague here: we run millions of dollars of construction a year. At that volume we pay contractor prices for materials and keep steady crews working twelve months a year, so a given renovation costs us roughly half of what a homeowner pays for the same job.
That is where our margin is. It is also why fixing the house up yourself first rarely pays off. You would be paying retail for the work and counting on the sale price to cover it, and it usually does not. We earn our money on the construction side, not on the price we pay you.
If the figure does not work, say so; we would rather know than try to talk you round. We will look at what is going on and tell you honestly which options make sense, including the ones without us. Listing with an agent is the better route for plenty of sellers, and we will tell you if it is yours.
What to do next
Nothing has to be legalized, opened up, drawn or approved before we buy. The unpermitted work stays exactly as it is through the closing, and the file becomes ours.
That is not a concession, it is simply the work we do. We take on the file, commission the drawings, meet the inspectors on site and pay for the corrective work when one of them asks for it. What would be a year of your life, spent on a house you have already decided to leave, is a line in our budget.
Common questions
Will unpermitted work stop a buyer getting a mortgage on an Elmont house?
It often does. A lender wants the certificate of occupancy to match what is physically there, and unpermitted work means it does not. The appraiser flags the discrepancy, the underwriter asks for the permit, and the buyer is suddenly waiting on a town approval nobody can put a date on. That is the mechanism behind most failed sales on houses with unpermitted work. We are not borrowing, so there is no appraiser and no underwriter to satisfy.
Do I have to pull permits before selling my Elmont house?
No. Pulling permits after the fact is slow and expensive, and it is work we are already set up to do. Spending your own money and months on it before you have an offer in hand rarely makes sense.
The previous owner did the unpermitted work. Does that change anything?
It is extremely common and it does not affect our offer. What you are personally exposed to is an attorney question, but unpermitted work done by a previous owner is not a reason we walk away.
Will the town find the unpermitted work when I sell my Elmont house?
A buyer's attorney will usually order a municipal search, which is where open permits and missing sign-offs surface. Selling to us does not require that search to come back clean.
There is already a violation for the unpermitted work. Can you still buy?
Yes. An open violation on unpermitted work is a file we take on at closing along with the house. It affects the number the way any real cost does, not the willingness.
How much does unpermitted work take off the price of an Elmont house?
Enough to cover what it realistically costs to put right, and no more than that. We will show you how we arrived at the figure, and we do not move it afterward.
