Planning a bathroom or interior remodel in the Town of Brookhaven

What this page covers

This planning page is for owners of single-family and two-family houses in the Town of Brookhaven who are thinking about a bathroom, kitchen or interior renovation. It is not a claim that service is available in Brookhaven. Structural alterations, additions and new construction are not current planned services, and licensing, local eligibility and launch decisions remain open.

Town, village or shared hamlet

Three checks before you describe the bathroom

Suffolk County's towns-and-villages directory lists these incorporated villages under the Town of Brookhaven: Belle Terre, Bellport, Lake Grove, Old Field, Patchogue, Poquott, Port Jefferson and Shoreham, plus Mastic Beach. The New York State Department of State lists Mastic Beach in its table of dissolved villages, with a date of 12/31/2017, so a county directory entry is not by itself proof that a village still exists.

Village examples

Village processes are not interchangeable

The villages inside the town describe their building processes in different ways. Four examples, as published by the villages themselves and accessed on 2026-11-08:

• Port Jefferson: the village Department of Building and Planning says it administers and enforces the New York State Uniform Fire Prevention and Building Code, and its FAQ says a building permit is required for new homes, additions, alterations and manufactured homes. It also lists a FOIL application for public access to records.
• Bellport: the village Building Department says building permits are required under village code and state law, and asks residents to contact the department to find out whether a building permit is required.
• Old Field: the village says all permits are approved, reviewed and closed by the Board of Trustees at their monthly meetings, and that covered work may not start before the village issues a permit.
• Lake Grove: the village's online forms page lists a building permit application and residential building permit filing requirements.

The practical point for a bathroom brief: a review step, document list or meeting cycle that applies in one village should not be assumed for a house in another village or in the town. Ask the office that covers the house how its review works before you plan around it.

Town records

Town records you can look up before bids

For property under town jurisdiction, the Town of Brookhaven runs an online Public Records Search that says it lets users look up permits, certificates, registrations, licenses and more. The town's former online FOIL page says its FOIL system has moved to a new online portal.

1. Search the town records portal for the address and note what permits and certificates appear.
2. List what you know has changed in the bathroom or house since those records, and mark the rest as unknown.
3. If something you expected is not shown, ask the town how to request it, rather than assuming it does not exist.
4. For a village property, ask that village how it handles record requests.

Bathroom scope

Then write the bathroom brief

Once the office is known, describe the bathroom in terms a bidder can price consistently: which fixtures stay, which are replaced and which you would like to move; whether this is the only bathroom in the house; who uses the room and whether easier access matters; how the room is ventilated now; and which finishes are chosen and which are still open.

The bathroom remodeling page shows scope examples. The bathroom materials and layout guide and bathroom cost factors help with selections and budget drivers, and renovation permits in NYC vs Suffolk explains the town-and-village system in general. For more than one room, see whole-home renovation.
