The conversation nobody plans for
A Coram seller is at the kitchen table with the listing paperwork, and somewhere in the middle of it comes the question about whether the house has an apartment in it. Downstairs there is a bedroom, a bathroom, a sink, a stove and a door to the driveway. It was built for a parent in 2003, or it came with the house, or a tenant has been in it for six years. Nobody in the family has ever called it an apartment. The town has a name for it, and the name matters at closing.
Why this comes up on Coram houses
Of the seven houses I have closed in Coram, the median year built is 1971 and three of the seven were built before 1970. That is the era on Long Island when a finished lower level with its own entrance was ordinary, and it is the housing stock where a second kitchen tends to appear later without paperwork. I am not saying anything here about houses I did not sell. I am saying that on the ones I did, this is the question that turns up.
What Brookhaven actually requires
An accessory apartment is a separate living area with a kitchen inside the principal dwelling. Brookhaven does not permit one in a detached structure, and it allows only one per property. The rule that catches people is the occupancy one:
The owner(s) of the lot upon which the accessory apartment is located shall reside within the dwelling that contains the accessory apartment.
Town of Brookhaven Town Code section 85-258
The owner may live in either unit, and where a property has several owners, the ones living there must hold at least half of it. The apartment may have no more than one bedroom, it needs its own entrance, which may open off a shared foyer, and it needs at least one off street parking space of its own.
Size is tied to the size of the house. The town's own guidance puts the range at 300 to 650 square feet and no more than 40 percent of the habitable area, with larger apartments allowed at the review board's discretion on a sliding scale that tightens the percentage as the square footage rises.
Two things are worth flagging as unsettled rather than stated flatly, because the sources do not agree and a seller should ask rather than assume. The town's frequently asked questions say the first provisional licence runs two years and renewals run two years. The codified text of section 85-258 as published on one code site describes an initial period of up to three years and renewals of up to five. Ask the Building Division which applies to your address before you put a number in a listing.
What actually happens in the sale
Three separate things, and they are often confused with each other.
The disclosure. New York requires the seller to complete the Property Condition Disclosure Statement and deliver it before the buyer signs a binding contract. Until March 2024 a seller could decline and hand over $500 at closing instead. That option is gone. The State Bar Association describes the amendment as removing the credit outright and adding seven flood questions, taking the form from 49 questions to 56. The form carries its own warning:
A KNOWINGLY FALSE OR INCOMPLETE STATEMENT BY THE SELLER ON THIS FORM MAY SUBJECT THE SELLER TO CLAIMS BY THE BUYER PRIOR TO OR AFTER THE TRANSFER OF TITLE.
New York Real Property Law section 462(2)
The exposure is not the apartment. It is answering a question about it in a way the seller knows is not true.
The town. Brookhaven raised its illegal housing penalties, and the current figures on the town's own page are a minimum of $2,500 and a maximum of $6,000 for a first offence, with a $5,000 minimum on a second. The town takes complaints by phone and publishes a rental licence lookup, so the status of a property is not private information.
The licence, if there is one. This is the one that surprises sellers who did everything correctly. A Brookhaven accessory apartment licence is granted to the owner, not attached to the house, and it terminates on transfer of title. A buyer who wants to keep using the space as an apartment applies in their own name, meets the owner occupancy rule themselves, and takes their turn at the review board. So a legal apartment is not a feature that conveys. It is a condition the buyer has to re establish.
What to do, in order, before the house goes on the market
- Find out what the town has on file for the address. The Building Division holds the certificate of occupancy and any licence history, and that is the factual answer to a question the seller may only half remember.
- Answer the disclosure statement from what is actually known, and put unknown where it is unknown. The form allows that answer and it is safer than a guess.
- Decide with the attorney whether to apply, to remove the second kitchen, or to sell as it stands and price accordingly. All three happen. The wrong move is deciding nothing and letting it surface after the inspection.
- If the apartment is currently rented, deal with the tenancy on its own timeline. It does not resolve itself at closing.
- Do not describe the space in the listing in a way the certificate of occupancy does not support. That is a representation, and the file at the town is the record.
