Rensselaer County, New York Building Permit Guide

No countywide building permit exists in Rensselaer County. The cities of Troy and Rensselaer, the 14 towns and the villages of Castleton-on-Hudson, East Nassau, Hoosick Falls, Nassau, Schaghticoke and Valley Falls each answer for building work inside their own lines. The county’s Department of Health handles the wastewater side: its Public Health Engineering staff review engineered plans for individual septic systems, issue the permits to construct them, inspect new and replacement systems and approve the sanitary facilities in realty subdivisions.

What requires a building permit in Rensselaer County?

The local lists are long. The City of Rensselaer requires permits for all structural, roof and siding work and some repairs. Sand Lake names new homes, commercial buildings, additions, renovations, accessory structures, pools, wood stoves, fireplaces, furnaces and air conditioning, plus signs, fences and sheds. Brunswick asks for permits for sheds over 80 sq ft, roof replacement, land clearing and timber harvesting; Schodack for fences, replacement furnaces, roofing, siding and windows. Nassau adds a driveway construction permit and a separate zoning permit.

What the municipalities decide and what the state holds

All 22 municipalities enforce the 2025 Uniform Code and Energy Code. Local law decides the rest: zoning and land-use permits, which small jobs need a permit, how the fee is figured and how applications are filed. Rensselaer County is not among the twelve counties the Department of State lists as having opted out of the enforcement of the Uniform and Energy codes.

Rensselaer County building department: who handles permitting

Every city, town and village the Census Bureau counts in the county is listed. Town offices stop at village lines, and two villages straddle towns: Nassau village lies mostly in the Town of Nassau with a corner in Schodack, and Valley Falls lies mostly in Pittstown with a sliver in Schaghticoke. The cities are separate from every town.

Many rural offices keep short hours: Petersburgh’s officer works three early mornings a week, Pittstown’s about ten hours over three days, and Schaghticoke and Stephentown by appointment. Three small villages, Schaghticoke, Valley Falls and East Nassau, post no building information online, so call the village office before work starts. Hamlet names in a mailing address are not municipalities; the tax map decides.

What Rensselaer County itself does

• Department of Health, Environmental Health (1600 7th Avenue, Troy; 518-270-2632): Public Health Engineering reviews septic plans prepared by New York licensed professionals, issues permits to construct individual sewage treatment systems and tank replacements, inspects new and replacement systems, answers complaints of failed systems, approves realty subdivision sanitary plans and helps residents with well water questions. Its rules are Articles 2 and 9 of the county sanitary code.
• Highway Department (124 Bloomingrove Drive, Troy; 518-283-0973; weekdays 9 a.m. to 5 p.m.): maintains county roads; ask it before a driveway or other work touches one.
• Economic Development and Planning (333 Broadway, Suite 320, Troy; 518-270-2914): the county planning office.

Rensselaer County permit types and applications

Residential permits

Each office uses its own forms and channels. Troy takes paper applications only and payment by check or cash. East Greenbush files through MyGov and collects the fee after approval. Sand Lake offers online building applications. Schodack wants a notarized paper application at Town Hall, and Brunswick a zoning verification form with the building application. Pittstown posts its application with written instructions and a driveway permit, and Grafton posts its building permit form online. In Troy the fee rests on the full building cost, trades included but not land, landscaping or driveways, and the stated cost must be backed by bids, proposals or contracts or the Director of Code Enforcement sets it. Work in a Troy street takes separate excavation, encroachment, curb cut or barricade permits, the last covering dumpsters, moving pods, lifts and scaffolding.

Commercial permits

Commercial projects add stamped plans and, in most towns, site plan review by the planning board. In the City of Rensselaer the Building Department also enforces the zoning code and inspects for the certificate of occupancy. A commercial building on a private system needs an engineer’s septic design reviewed by the county; plans other than individual systems or realty subdivisions go on the county’s EH800 form.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning: local zoning and planning boards; Nassau publishes zoning fees updated January 11, 2024, and Stephentown sells copies of its updated Land Use Regulations for $10 at the Town Clerk’s office, or $12.50 by mail with postage included.
• Septic: on a lot without sewer, the county plan approval and permit to construct.
• Driveways: the town or county highway office that owns the road.
• Moratoria: East Greenbush adopted a data-center moratorium in July 2026; its guide has the details.
• Flood zones: 21 of the 22 municipalities participate in the National Flood Insurance Program; the Village of Valley Falls is listed by FEMA among communities not in the program, suspended since January 7, 2016.

Building permit and septic fees in Rensselaer County

Every municipality sets its own building fee; Brunswick fills in the fee on its form at review, and East Greenbush computes it in MyGov. The rows below are the published building rules for two places with finished guides and the county’s sewage program fees.

A new house on a conventional septic system therefore pays the county $300 for plan approval plus $75 for the permit to construct, $375 in all, on top of the local building fee; a system that needs fill raises the permit part to $150. In Schodack a 2,400 sq ft house pays 2,400 times $0.25, or $600, for the building permit, certificate of occupancy included.

Trade permits and who may pull them

The county has no trade licensing program on its website. The City of Troy licenses its own master electricians and plumbers after a city exam, with yearly renewal. In the towns the usual rule is an approved third-party electrical inspection agency: Brunswick and Schodack each publish their accepted agencies. Every office needs proof of workers’ compensation and disability insurance, or the state exemption form, before it issues. Septic systems are designed by a New York licensed professional, usually an engineer, before the county reviews them.

How to get a building permit in Rensselaer County

Review, corrections and what causes delay

The City of Rensselaer quotes 7 to 10 days for a typical permit, East Greenbush about 7 to 10 for residential work and Brunswick 5 to 15 working days. Files stall on missing septic approval, insurance certificates, plans without a required stamp (Brunswick sets the line at $20,000 or more of work, a second story or an addition over 300 sq ft), and on officers who are in only a few hours a week.

Inspections and certificates

Book inspections with the issuing office: the City of Rensselaer needs at least 24 hours’ notice, and part-time town officers need a call during their hours. The county inspects new and replacement septic systems itself. The final local inspection leads to a certificate of occupancy or compliance; in the Village of Hoosick Falls every rental unit must also pass inspection and receive a certificate of occupancy before new tenants move in.

New York building code

New York builds on one statewide code, the Uniform Code, outside New York City; the 2025 edition and 2025 Energy Code took effect on 31 December 2025 (the all-electric provisions remain suspended by court order). Cities, towns and villages administer it, and local standards stricter than the code need Code Council approval. The Uniform Code in New York
