Getting a New Rochelle Building Permit for a Bathroom Remodel

A bathroom remodel that touches the plumbing, the wiring or the framing needs a New Rochelle building permit from the Bureau of Buildings, the City's building department. The City's own permit page states the rule in one line: "Obtaining a building permit is a New York State requirement, not a local ordinance." Every application filed since December 31, 2025 must comply with the 2025 New York State Uniform Code. This guide follows a job in the order you meet the rules: what needs a permit, how the application is filed, who may do the plumbing and electrical work, which inspections follow and what they measure, and the asbestos, lead, noise and dumpster rules around the work.

We file the permit, book each inspection and keep the approved plans on site. This page shows what a lawful job in New Rochelle looks like from the first drawing to the final inspection, and what to ask anyone you hire. Fees are linked where they come up below, and published remodel prices by project are on our bathroom cost page. The last section covers the building departments of Larchmont, Mamaroneck, Pelham, Scarsdale, Bronxville, Eastchester, Rye and Harrison, which follow the same State code with their own forms, hours and fees.

What needs a permit under the 2025 Uniform Code

New York adopted the 2025 Uniform Code of New York State, based on the 2024 International Code Council books with New York amendments, and it took effect on December 31, 2025. From that date every permit application must comply with it; the transition window, when an applicant could still choose the 2020 code, closed on December 30, 2025. The 2025 Residential Code of New York State is a derivative of the 2024 International Residential Code. Enforcement is local: every city, town and village administers the Uniform Code within its borders. In New Rochelle, City Code section 111-8 requires a permit before anyone begins the alteration, improvement or conversion of a building or part of one, or performs "any work which must conform to the State Code."

The State's permit rule, 19 NYCRR 1203.3, lets a municipality exempt listed categories of work, but only where its own code enforcement program says so expressly. Three of them touch a bathroom: "painting, wallpapering, tiling, carpeting, or other similar finish work"; "replacement of any equipment provided the replacement does not alter the equipment's listing or render it inconsistent with the equipment's original specifications"; and "repairs, provided that the work does not have an impact on fire and life safety," such as the structural system, the required means of egress or the fire protection system. An exemption, the rule adds, is not an authorization to break the codes. New Rochelle's published list of work that needs no permit names only driveway resurfacing, siding, emergency roof repairs and painting. A bathroom is not on it.

City Code section 111-9C lets the Building Official waive a permit, at his discretion, only when the work passes all five of its tests: it is an alteration to an existing building; its construction cost is under the ceiling the section sets, which we list with the City's fees on our New Rochelle numbers page; structural features are not affected; fire-safety features such as smoke detectors, sprinklers, fire separations and exits are not affected; and "Electrical, plumbing and heating systems are not affected." A remodel that moves a drain or adds a circuit fails the fifth test. A mapped flood zone adds a second permit: section 111-33 requires a floodplain development permit for any development there, and under section 111-31 a remodel costing 50% or more of the structure's market value is a substantial improvement, which brings the whole house under the flood elevation rules.

Filing with the Bureau of Buildings through CitySquared

Applications go in online. The City's How to Apply page links its permit system, CitySquared, where the applicant logs in or registers, chooses the Buildings department and the permit type, and adds the people on the job, such as the architect, contractor or engineer. City Code section 111-10C lets the owner or lessee, an agent of either, or the architect or engineer on the job apply, and section 111-10A asks for the application to be signed and acknowledged before a notary public. Plans come with it: section 111-10G calls for at least two copies of specifications and plans drawn to scale, and section 111-10B has the work designed by a registered architect or a professional engineer. We file as your agent and upload the drawings as a PDF, the format the portal asks for.

The same step asks for "any and all insurance information required (Ex: Workers comp, Liability, Disability, Home Improvement, etc)." Workers' Compensation Law sections 57 and 220 bar a permit office from issuing a permit without proof of coverage, and the Department of State's permit handout names the forms: C-105.2, or U-26.3 from the State Insurance Fund, for workers' compensation, and DB-120.1 for disability and Paid Family Leave. Form CE-200 is an exemption for an entity with no employees, and it is job-specific: "a separate certificate will be required for each building permit." The BP-1 affidavit is the form for a homeowner listed as general contractor on a one- to four-family, owner-occupied house. ACORD forms are not accepted as proof. Westchester County requires a home improvement license for this work, and the license number must appear on the contract; the County's Department of Consumer Protection confirms any license.

No permit issues until the Chapter 133 fees are paid (section 111-13A); we table the City's fee schedule and the towns' on our New Rochelle numbers page. Once issued, the permit is posted "in a conspicuous location on the site of operations" until the work is complete (section 111-11H). Under section 111-11C it becomes invalid if work has not started within 90 days of issue, or if work is suspended or abandoned for six months after it starts; for cause, the Building Official may grant extensions of up to 90 days each, in writing. An application that never reaches issue is deemed abandoned six months after filing unless it is being diligently prosecuted (section 111-10L). Design changes after issue go back through CitySquared as an amendment request. We track the dates on every permit and file for an extension before one lapses.

Plumbing and electrical: who may file and who signs off

Plumbing in New Rochelle is governed by City Code Chapter 242, which incorporates the plumbing standards of the Plumbing Code of New York State. Section 242-5A(1) makes it unlawful for any person to install, alter or repair a plumbing system in the City without a Westchester County certificate of qualification, earned by examination and registered with the City's Plumbing Inspector. Section 242-6 goes further: plumbing permits issue only to a holder of that certificate from the Westchester County Examining Board of Plumbers who is a registered master plumber at the Plumbing Inspector's office. The rule says "any person," and the sections that set it out make no exception for owners doing their own work. Our master plumber files the plumbing permit.

Before work starts, the master plumber files a plan with the Bureau of Buildings showing the plumbing to be installed; the Plumbing Inspector approves it, and one stamped copy stays on the premises (section 242-7A). A notification card goes to the Plumbing Inspector as well (section 242-7B). Like-for-like repairs need no drawings, but that exemption ends wherever soil, waste or vent lines are new or replaced. The City sets its own minimum trap and drain sizes in section 242-12A(1): 1 1/2 inches for a bathtub or lavatory and 2 inches for a shower stall, so a tub-to-shower conversion here takes a larger drain; section 242-12D(1) keeps sink wastes out of bath wastes. At the end, the Plumbing Inspector issues a certificate of approval for the owner, and the system may not go into regular use until then (section 242-10F).

Electrical permits are issued by the Bureau of Buildings and charged under Chapter 133, but the sign-off comes from an inspection agency, not the City. Under section 111-18C, when an electrical installation is complete the electrical contractor submits "a certification of satisfactory completion" issued by the New York Board of Fire Underwriters or another electrical inspection agency authorized by the New Rochelle Board of Electrical Examiners and City Council. Westchester County adds its own rule: "Plumbers and Electricians must obtain a trade license from Westchester County in order to work in the county," and the County tells homeowners to ask to see the license card. The electrical standard is NFPA 70, the National Electrical Code; a comment in the Code Council's record on the 2025 rules names its 2023 edition, and the Department of State did not dispute it.

The inspections in order, and the dimensions they check

City Code section 111-18A makes the owner, applicant or agent responsible for telling the Building Official that work is ready and scheduling the inspection; as your agent, we book each one. The State's minimum list in 19 NYCRR 1203.3 runs from the worksite before the permit issues through framing, the building's systems and Energy Code items such as insulation, to a final inspection. On a bathroom the order follows the walls. Rough plumbing is inspected while the cavities are open, because section 242-10E(1) bars covering plumbing "until it has been inspected, tested and approved," and plumbing covered early must be uncovered; we book the electrical rough-in at the same stage. Work completed without the inspector's approval pays twice the Chapter 133 fee and needs an architect's or engineer's certification before it can be approved (section 111-42C(6)). The final inspection comes before the certificate of occupancy or compliance (section 111-18A(7)).

The rough inspections check layout against the model code behind New York's 2025 Residential Code. Its spacing rule, Section R327.1 with P2705.1, keeps a toilet, lavatory or bidet at least 15 inches from its center to a side wall, partition or vanity, with at least 21 inches clear in front. Its smallest shower is 30 inches by 30 inches, with at least 24 inches clear in front of the opening. Our shower valves are ASSE 1016 automatic compensating valves, and the installer sets the limit stop to the maximum the local code allows, usually 120 degrees F. The wiring is checked against the National Electrical Code: GFCI protection for bathroom receptacles under 210.8(A), a 20-ampere circuit for those receptacles under 210.11(C)(3), and no receptacle within 3 feet horizontally of a tub or shower under 406.9(C).

Before tile, the pan gets the model code's flood test (P2503.6): water at least 2 inches deep at the threshold, held for at least 15 minutes, without leaking. The liner slopes at 2-percent to the weep holes and carries no nail or hole less than 1 inch above the finished threshold (P2709.3). Shower walls take a non-absorbent finish to at least 6 feet (R327.2) over cement, fiber-cement or glass-mat backer (R702.4.2). Glass with its bottom edge less than 60 inches above a standing surface near a tub or shower is in a hazardous location and takes safety glazing (R324.4.5). Ceilings stay at least 6 feet 8 inches (R313). Section R325 calls for a window of at least 3 square feet, half of it openable, or artificial light and an exhaust fan ducted directly outside; New York's 2020 table set that fan at 50 cfm intermittent or 20 cfm continuous.

Asbestos, lead, work hours, dumpsters and the eight towns

Half of New Rochelle's housing was built in 1955 or earlier, so a State rule and a federal rule shape demolition. Industrial Code Rule 56 (12 NYCRR 56-5.1) requires an asbestos survey before renovation in any building whose original construction began before January 1, 1974; an asbestos contractor holding a New York license performs it, and a copy goes to the office that issues the permit. The rule excuses the owner of a one- or two-family house who hires the work out and does not direct it from ordering the survey, so we arrange it. EPA's Renovation, Repair and Painting rule covers paid work that disturbs paint in homes built before 1978; its small-job exception stops at 6 square feet of painted surface per room inside, and demolition of painted surfaces is always covered. You receive EPA's Renovate Right pamphlet no more than 60 days before work begins.

In residential districts, construction noise is limited to 8:00 a.m. to 7:00 p.m. on weekdays and 10:00 a.m. to 5:00 p.m. on Saturday and Sunday (section 213-22); at other hours, and all day on state legal holidays, work heard beyond the property line is presumed unreasonable. Section 213-5G(1) sets matching weekday and weekend windows for power tools used outdoors, such as a tile saw. A dumpster on a street, sidewalk or other public place needs a written permit from the Commissioner of Public Works, valid for up to 30 consecutive calendar days (section 281-48A); the container carries two reflectors on each side and its owner's name in letters at least three inches high. Materials stored on the street need a Public Works permit (section 111-26C), and a commercial vehicle may stand on a residential street for one hour unless delivering or working at the house (section 312-43D).

Each of the eight towns runs its own department under the same State code. Larchmont's Building/Engineering Department, at 120 Larchmont Avenue, takes two hard copies of plans, and its FAQ says bathroom alterations need a permit; homes on Murray Avenue or Weaver Street belong to the unincorporated Town of Mamaroneck instead. The Village of Mamaroneck files at 169 Mount Pleasant Avenue; the County lists the Town's office at 740 West Boston Post Road. Pelham's two villages each permit their own homes, at 195 Sparks Avenue and 4 Penfield Place. Scarsdale's Building Inspector aims to inspect within 24 hours of a request. Bronxville's code allows major alterations only on weekdays, 8:00 a.m. to 6:00 p.m. Eastchester's Town department sits at 40 Mill Road, and Tuckahoe's at 65 Main Street. Rye's Building Department enforces the code under Chapter 68, and Harrison's department takes applications only on paper or by mail.
