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.
What we bring to unpermitted work, beyond the money
Most owners get here after one call to the building department that raised more questions than it answered. What we can offer first is somebody who has been through this repeatedly telling you plainly what your options are.
If selling suits you, we buy with the unpermitted work in place. If the addition could be legalized without much trouble and the house would net more legalized and listed, we will say so and give you the name of an expeditor. Neither conversation costs you anything.
What this looks like in Merrick specifically
Merrick is roughly 22,040 people in Nassau County, ZIP 11566, and the housing stock is mostly hi-ranch, colonial, split-level. Around Merrick Road and Sunrise Highway, most of it is old enough that the mechanicals are on their second or third life. The Merrick stop pulls buyers who commute, which supports the good houses and does very little for the ones that need a roof. We have been buying across Nassau County for 15+ years. We know what the Merrick Union Free School District does to a resale price, which blocks still have oil tanks in the ground, and what a house like yours is actually worth here.
The median is up 8.68% year over year as of 2026-10. A firming market gives you a little room for error on price, which is worth more than it sounds when the house is not in showable condition. At a $902,038 median, Merrick buyers are paying enough that they expect the house to be finished. A dated kitchen is a deduction in a cheaper market and close to disqualifying in this one, which is why unrenovated houses here sit while the renovated ones move. The median house here goes under contract in about 24 days, which is quick for Long Island. It is also a figure that only applies to property in showable condition.
Appraisals, unpermitted square footage and the certificate of occupancy
A mortgage lender is lending against the house the town has on record, not the house you have been living in. When an appraiser measures finished space that does not appear in the certificate of occupancy, the questions start.
What usually follows is a request for permits, or for the work to be legalized before funding. That lands on the seller, on a deadline, at a pace the building department sets rather than the buyer. It is the most common way this ends an otherwise healthy contract.
Why legalizing unpermitted work takes longer than anyone expects
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 Merrick
These are the two routes open to you with a house with unpermitted work, priced against what Merrick houses actually sell for.
Work it against Merrick's own numbers. The median sale here is $902,038. A 5% commission on that is $45,102, and seller closing costs of about 2% add roughly $18,041. Those are costs we can cover on our side. That is $63,143 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 Merrick the median house takes about 24 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 69 to 84 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 | $902,038 (Merrick median) | Our written offer |
| Commission | −$45,102 | None |
| Seller closing costs | −$18,041 | We can cover them |
| Repairs before listing | Out of pocket | None |
| Cleanout | Yours | Ours |
| Showings | Until it sells | One visit |
| Listed to signed contract | 24 days (Merrick 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 | 69 to 84 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 | $838,895 | The number we put in writing |
Assumptions: 5% commission and about 2% seller closing costs on the listing side, and both move from deal to deal. Repairs and the cost of holding the house are not deducted, since they vary by property. A well-kept house with a good agent can come out ahead of a cash sale, and if that describes yours we will say it.
What unpermitted work costs you on the Merrick open market
The median house in Merrick sold for $902,038 and took about 24 days to go under contract, then another 45 to 60 days waiting on the buyer's mortgage. That is 69 to 84 days in total, for a house that was ready to show on day one. That is the ordinary path, for a house whose paperwork matches the building.
Unpermitted work adds a third wait that belongs to the town rather than to either party. You would be funding drawings and applications up front, on a house you are leaving, with no certainty about the timeline and none about the outcome. Run that against a clean sale on a date you choose before you commit to it.
How we arrive at a number on a house with unpermitted work
On a house with unpermitted work we start from the end: what it sells for once the work is done. From that we take away the cost of the work and a margin for the chance that we have misjudged either one. That is the whole method. Nothing is hidden in it.
- What it is worth repaired. Not the Merrick median of $902,038 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 Merrick the stock is largely hi-ranch and colonial, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Merrick house goes under contract in about 24 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. Walls and floors hide things until they come up. We price for that uncertainty, and it accounts for much of the distance between a cash offer and a retail price.
How we can pay this and still make it work
Most cash buyers skip this part. We do not. We run millions of dollars of construction a year, so we buy materials at contractor prices and keep our crews busy all year. The same renovation costs us roughly half of what you would be quoted as a homeowner.
That difference is how we make money. It is also why renovating before you sell seldom comes out ahead: you would pay retail for the roof and the boiler and then hope a buyer pays you back for them. Most of the time they do not. Our margin comes from building for less, not from buying from you for less.
If our number does not work for you, tell us. We would much rather hear it than push. We will go through your situation and give you a straight view of your options, including the ones that leave us out. A lot of people do better listing with an agent, and if you are one of them we will tell you now rather than have you find out later.
We buy Merrick houses with the work left unpermitted
Tell us everything, including the parts you would rather not write down. When the deck went on, who finished the basement, whether a permit was ever pulled, whether the town has ever sent a letter about it.
None of it makes us withdraw and all of it makes our number solid the first time. Deals fall apart on partial information, and being renegotiated late is exactly the experience you are trying to avoid when there is work like this on the house.
Common questions
Will unpermitted work stop a buyer getting a mortgage on a Merrick 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 Merrick 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?
Not for us, and not for the town either, because the file follows the property rather than the person who built the addition. It is one of the most common versions of this we see.
Will the town find the unpermitted work when I sell my Merrick house?
What the town knows and when is not something anyone should guess at. Your attorney can tell you what a sale in your situation actually triggers. From our side, nothing you disclose changes our offer.
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 a Merrick 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.
