Bathroom Remodeling in Mamaroneck, NY
Serving Mamaroneck, NY from New Rochelle.
Bathroom remodeling in Mamaroneck, NY means two permit offices and two codes. The Village of Mamaroneck straddles the Towns of Mamaroneck and Rye and runs its own Building Department; the unincorporated Town of Mamaroneck, 5.7 square miles outside both of its villages, is permitted by the Town. Some streets change hands partway along: the Village of Larchmont's 2023 roads list splits Rockland Avenue, Fenimore Road, Old White Plains Road, Forest Avenue and Hommocks Road between the Town and the Village of Mamaroneck. Both offices enforce the same state code, the 2025 Uniform Code in force since December 31, 2025, but the filing, the trade rules and the work hours differ, so the first line of our estimate names the office that will issue the permit.
The second question is water. The Sheldrake and Mamaroneck Rivers flood, the County's 2021 hazard plan calls the Washingtonville area a known flood-prone area, and the remnants of Hurricane Ida flooded homes in the village in September 2021. Both codes now count improvements over time: the Village's Chapter 186 and the Town's Chapter 110 each define a cumulative substantial improvement as work that reaches 50% of the structure's market value when counted over 10 years. In a mapped flood zone a bathroom is measured against the house's recent permits as well as its own cost, and our full bathroom remodel plans start from that permit history.

Village or Town of Mamaroneck: permits, river flooding and work hours
The Village Building Department works from the third floor of the Municipal Building at 169 Mount Pleasant Avenue, open 8:30 a.m. to 4:30 p.m. Monday through Thursday and until 2 p.m. on Friday. It takes building, plumbing, electrical and dumpster permits on paper: two physical sets of plans, one full size and one at 11 x 17, signed and sealed by a New York State architect or engineer, with a Short Environmental Assessment Form, a copy of the home improvement license the County issued to the contractor, liability coverage naming the Village as certificate holder, and the State's workers' compensation and disability forms, C-105.2 and DB-120.1. Chapter 350, adopted in 2023, exempts tiling and like-for-like equipment replacement, and a permit is invalid if work has not begun within six months of issue.
Review boards reach a bathroom only in particular cases. The Village Board of Architectural Review hears construction and reconstruction, which section 6-3 defines as additions and structural alterations above a set estimated cost, and in the Central Business District such work goes to it whatever the cost; a non-structural interior remodel falls outside the definition. The Town's board, under a rule adopted in 1990, does not receive interior work in a one- or two-family house. Historic preservation in the Village works differently: under Chapter 218 a designation "may apply to the exterior only or to the interior only, or to both," and a material change of appearance in a designated feature needs a certificate of appropriateness first. Protected sites in the chapter include the Old Mill, the Skinny House and the Bedelle Cottage and Homestead, and we check an address against that list before demolition.
In the unincorporated Town, Chapter 106 requires a separate building permit for any alteration or improvement and exempts only ordinary repairs that are not structural, a category that excludes cutting walls or partitions. Applications carry plans and specifications in triplicate, a survey of the property and the estimated total cost, and a permit is effective for one year with up to two six-month extensions. Westchester County's directory of building departments gives the Town office's address as 740 West Boston Post Road. Under section 158-3, plumbing in the Town requires a Westchester County license, though no plumbing permit is needed when fixtures are replaced without disturbing any drain, waste or vent pipe; a like-for-like bathtub replacement qualifies only if that piping stays untouched, and a tub-to-shower conversion usually moves the drain. Electrical work is filed with the New York Board of Fire Underwriters, and nothing is energized until its certificate of compliance issues.
Village plumbing follows Chapter 278. Whoever does it must hold a current Westchester County plumber's license; the first inspection comes when the soil, waste and vent lines are in place and before anything is covered, and a leak inspection follows completion. Village electrical work is inspected by an independent agency the Village Manager deputizes, and current may not be supplied until its certificate issues. Working hours differ by side of the line. The Village allows noisy construction from 8:00 a.m. to 6:00 p.m., Monday through Saturday, never on Sundays or on listed holidays that include Yom Kippur and Thanksgiving, and it confines demolition to weekdays. The Town bars construction equipment heard beyond the property from 8:00 p.m. to 8:00 a.m. on weekdays and lets it run between 9:00 a.m. and 6:00 p.m. on Saturdays and between 9:00 a.m. and 5:00 p.m. on Sundays. A curbside dumpster in the Village may stay no longer than 10 working days and must be lit with lanterns.
FEMA's July 2021 figures in the County plan count 995 flood insurance policies, 1,982 claims and 245 repetitive-loss properties in the village, and 240 policies, 626 claims and 62 repetitive-loss properties in the unincorporated Town. On the Town side the Sheldrake River floods Brookside Drive and the Flats, and during Ida failed storm drains on Maplewood Street flooded basements and below-grade garages. The Village joined FEMA's Community Rating System after a 2014 determination, and its official rating of 8 means, by the Village's account, a reduction of up to 10% on flood insurance for many residents. In mapped A zones both codes put the lowest floor of a substantially improved house two feet above base flood level; for plumbing connections and other service equipment, the Village requires at or above the base flood elevation and the Town at least two feet above it.
The village counted 20,151 residents at the 2020 Census, and 56.8% of its homes are owner-occupied in the Census Bureau's 2020-2024 estimates. ACS 2024 5-year data give a median year built of 1953 for the village and 1945 for the Town as a whole; of the village's 7,858 units, 2,996 date from 1939 or earlier, 1,164 are in two-unit buildings and 1,001 in buildings of 50 or more. Westchester Joint Water Works, a non-profit formed in 1927 whose members are the Village, the Town and Harrison, draws New York City water at Shaft 22 in Yonkers and at Rye Lake in Harrison, adjusts pH with caustic soda and doses a blended poly-orthophosphate to limit corrosion, and reported a lead 90th percentile of 4.5 micrograms per liter for 2024. The County's Mamaroneck Sanitary Sewer District treats wastewater at its plant on West Boston Post Road. Harbor Island Park and the Emelin Theatre are in the village; the Hommocks Ice Rink and Myrtle Park are in the Town.

Questions
Mamaroneck FAQs
Is my house in the Village or the Town of Mamaroneck?
The part of the village west of the Mamaroneck River, 2.3 square miles, lies in the Town of Mamaroneck, and the rest of the village lies in the Town of Rye; the unincorporated Town is the land in the Town of Mamaroneck outside both villages. Because some streets cross from one jurisdiction to the other, the parcel's tax map number decides it, and we check it before anything is filed.
Do earlier projects count toward the 50 percent flood rule?
In both the Village and the Town, yes. The Village's Chapter 186, amended in 2024, and the Town's Chapter 110, adopted in 2022, count improvements cumulatively over 10 years, so a bathroom that is modest on its own can bring a house with other recent work to half its market value and into the elevation rules. We ask for the permit history of any house in a mapped flood zone before we price the bathroom, and our bathroom cost page lists the published ranges we price against.
What do the Village and the Town charge for permits?
Both publish schedules. The Village's was updated by its Board of Trustees on June 23, 2025, and the Town's Chapter A250 was amended by resolution on May 4, 2026. Each charges a filing fee plus an amount for every thousand of construction cost, and each doubles the fee for work started without a permit; the Village adds a penalty on top. The current figures for both are on our New Rochelle and town data page.
