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.

Published June 23, 2026 · Last verified June 23, 2026

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.

Review the Town of Brookhaven forms while considering the accessory apartment. Save the search date, property address, parcel or account number, and any license, citation, or application number with the purchase file so the town can locate the same record later.
