Brookhaven Accessory Apartments Need Their Own Paper Trail
A Brookhaven house with an accessory apartment should be checked for license status, ownership limits, and transfer issues.

An apartment inside a Brookhaven house needs document-level checking before a buyer counts it as income or living space. The town separates accessory-apartment license forms from house-rental license forms, so the paperwork is not interchangeable. The Building Division handles the special-permit application, a building permit will be required, and the license lasts two years. Properties must be deeded to people, not corporations or LLCs.
The FAQ adds that the owner may live in the main house or the apartment, and the apartment may have no more than one bedroom.
Ask for the license, permit, and renewal history.
Put Town of Brookhaven: Forms at the top of the folder for this Brookhaven question. Add the exact accessory apartment or home buying, the date searched, and the address, parcel, account, citation, or application number that belongs with it. The saved trail is useful because it gives Town of Brookhaven a cleaner starting point if the record has changed, moved, or been folded into a newer filing path. Brookhaven accessory apartment or home buying records are much easier to revisit when the source, date, and office route stay attached.
