Planning a kitchen or interior remodel in Commack
Commack is a hamlet that sits in two towns. Two houses with a Commack mailing address can be covered by different building departments, with different filing routes and different ways to look up past permits. Before a kitchen or bathroom brief goes to anyone for pricing, find out which town your house is in, using the address and the property's tax map record rather than the hamlet name.

What this page covers
This page is about kitchen, bathroom and interior renovation planning for owners of single-family and two-family houses with a Commack address. Structural alterations, additions and new construction are not current planned services. Project availability and service-area approval have not been established.
Why Commack is different
One hamlet name, two towns
The Suffolk County Clerk's town and district code table lists Commack with an asterisk, which the table defines as an area that lies in more than one township, and gives it the codes for both the Town of Huntington (400) and the Town of Smithtown (800). Commack is not marked as a village, and Suffolk County's list of incorporated villages in the two towns does not include it.
So there is no Commack building department. Depending on the address, the starting point is either the Town of Huntington's Building & Housing Division or the Town of Smithtown's Building Department. The same table codes Fort Salonga to the same two towns, so the checks below apply there too.
Before any estimate
Find the town for your exact address
County and town offices publish tools that start from the property itself rather than the hamlet name. Suffolk County's Real Property Tax Service Agency says its Tax Map Division is the sole authority responsible for creating and maintaining the county's tax maps, and its page links a public tax map viewer. The Huntington tools below accept a property's Suffolk County Tax Map (SCTM) number as a search term.
- Find the property's SCTM number on your tax records, or look the parcel up in the county's public tax map viewer.
- Search the Town of Huntington's free public GIS map by address or tax map number. The town describes it as covering all properties in the Town of Huntington and showing special districts such as villages.
- Check the Town of Smithtown side as well: its Building Department page links the town's property tax lookup and a public zoning map application.
- Ask the building department of the town your results point to whether it covers the address, before relying on its forms, fees or records.
Huntington side or Smithtown side
What changes once you know the town
The two towns publish different filing and records routes. The table summarizes what each town's own pages say, as accessed on 2026-11-08; the town planning pages have more detail.
| Topic | Town of Huntington | Town of Smithtown |
|---|---|---|
| Building office | Building & Housing Division: reviews plans, issues building permits, inspects work and issues Certificates of Occupancy | Building Department: issues permits for new construction, additions and alterations, inspects work in progress and issues certificates of occupancy |
| Filing | Applications go through the town's online application portal; the town lists separate residential application types, says the application fee is non-refundable and requires a "Citizen Service" account | An online residential permits page lists a set of projects that can be filed online, mostly outdoor and single-trade work; a combined kitchen, bathroom or multi-room interior is not named |
| Past permits | A Site History Summary search by SCTM number or address, which the town says identifies current permit applications and lists available data for older permits and Zoning Board of Appeals decisions | The department says its transactions are kept on permanent record, and links a Freedom of Information Law (FOIL) form for public access to records |
| More detail | Huntington planning page | Smithtown planning page |
Then write the kitchen brief
Once the town is known, the brief can be specific. Put the jurisdiction facts at the top so every bidder works from the same assumptions:
- The exact address, the SCTM number, the town you confirmed and the date you checked
- Which permits and certificates the town's records show for the house, and anything you know was changed since
- The kitchen in three columns: keep, replace and investigate, as described in the kitchen layout and storage guide
- Whether any bathroom or other room is part of the same project, and which rooms must stay usable during the work
- Selections still undecided, with an allowance noted for each
Scope examples are on the kitchen remodeling, bathroom remodeling and whole-home renovation pages. The permits guide explains the town-and-village system in general, and the estimate comparison guide explains what to line up across proposals.
Permits
Who issues building permits
Commack is coded by the Suffolk County Clerk to both the Town of Huntington and the Town of Smithtown (Smithtown: https://www.smithtownny.gov/109/Building-Department). It is not an incorporated village. Which town covers a particular Commack address was not verified for any address; confirm it with the town for the exact property. This is not a permit determination.

- Kitchens · Draft Cabinet refacing or replacement: what should you compare? Refacing changes what you see; replacement changes the boxes and often the layout. The useful question is which parts of your existing cabinets are worth keeping.
- Whole-home planning · Draft Renovating a two-family home: separate the two project briefs Two units mean two sets of rooms, decisions and occupants. Writing them down separately, with a third list for what the units share, keeps the scope readable for everyone who prices or plans it.
