Building permits for all of Rotterdam come from the building inspectors in the town’s Department of Public Works at Town Hall, 1100 Sunrise Boulevard (518-355-7575 ext. 395, weekdays 8 am to 4 pm). You submit the application, a stamped site plan and insurance certificates without payment; once approved, usually within 20 business days, the permit is paid for in cash or by check at Town Hall. Under the fee schedule updated May 13, 2026, a new house is $500 for the first 1,000 sq ft plus $0.40 per additional square foot.
What requires a building permit in Rotterdam?
The Building Department’s informational handout lists the work that needs a permit, and the town fee schedule prices it. A building permit is also the first step toward a Planning Commission site plan approval or a Zoning Board of Appeals variance.
Permit needed
- New construction, additions and alterations
- Structural changes and repairs, and finished basements
- Accessory structures, decks and sheds
- Fences (a separate fence permit)
- Above-ground and in-ground pools, to install or to remove
- Plumbing, including underground sprinkler systems
- Solar installations, priced as alterations
- Demolition
- Converting a two-family house back to a single-family home
No permit under Chapter 89
- One-story sheds and playhouses of 144 sq ft or less at a one- or two-family home
- Window awnings on a one- or two-family home
- Partitions or movable cases under 5 feet 9 inches
- Painting, wallpaper, tile, carpet and similar finish work
- Listed portable equipment and like-for-like replacements
- Repairs that leave structure, exits and fire protection untouched
Section 89-4B of the Town Code, adopted by Local Law 3 of 2023, is the rule that governs: a one-story shed of 144 sq ft or less at a one- or two-family home needs no building permit. The department’s handout still lists sheds among permit work without a size limit, so cite that section if you are told otherwise. Converting a two-family house to one family takes a building permit and removal of the second kitchen’s sink, stove and related supply, drain, waste and vent piping; the handout also lists the separate meters and separate entrance among the items involved.
What Rotterdam decides and what the state sets
Chapter 89, the Building Code Administration and Code Enforcement Program adopted by Local Law 3 of 2023, puts the state Uniform Code and Energy Code into effect and sets the exemptions and permit terms. Fees are set by Town Board resolution, most recently Resolution 155.26 of May 13, 2026. Zoning (Chapter 270), plumbing (Chapter 213), sewers (Chapter 230), water (Chapter 267) and flood damage prevention (Chapter 134) are town law.
Rotterdam building department: who handles permitting
Building inspection is one of the divisions of the Department of Public Works, alongside code enforcement, planning and zoning, water and sewer, and landfill operations. The building inspectors review applications, issue permits, carry out inspections and give final approval on projects, and the same department inspects water and sewer work. Rotterdam has no incorporated villages, so the town covers all 31,065 residents (Census 2025 estimate).

Rotterdam permit types and filing rules
Residential permits
The town posts separate forms for residential building, accessory buildings, demolition, handicap ramps, fences, plumbing, home occupations and new residential building packets. For a residential building permit, the residential application (revised February 2023) asks for:
- the completed application, and a residential plumbing application if plumbing is involved;
- three site plans signed and stamped by a New York design professional, showing setbacks to the property lines, existing and proposed utilities (with pipe type and size and the electrical service location), boundaries, any septic system and wells, and accessory structures;
- three sets of specifications and diagrams describing the structural, mechanical, electrical, plumbing and HVAC work;
- current liability and workers’ compensation certificates (the town keeps none on file, so every permit needs new ones) or a CE-200 exemption for an owner doing the work;
- county Health Department or town approval for a new septic system, and the town Well Regulation Form with a certified lab test for a private well.
Do not send a check with the application. When it is approved the applicant is called, and the property owner, applicant or contractor signs for and pays for the permit at Town Hall, in cash or by check only. The permit must be posted where it is visible from the street. A fence permit (revised January 2025) records the fence height along each lot line and comes with a letter if an agent applies for the owner. A truss-type construction notice goes to the Building Department and the fire department for new homes, additions and rehabilitations that use trusses or pre-engineered wood.

Commercial and multiple-dwelling applications need three complete sets of plans and a PDF on a flash drive, stamped by a registered design professional, covering use group, construction type, egress, exit lighting, accessibility, fire-resistant construction and fire protection, plus a site plan stamped by a licensed engineer. Review takes roughly 10 to 20 business days, a pre-construction meeting is held before any land is disturbed, and the certificate of occupancy needs a stamped as-built site plan and PDF. New nonresidential buildings and additions are $600 for the first 1,000 sq ft plus $0.60 per square foot beyond that, and multiple dwellings $500 plus $0.75. The Department of Public Works also bills fire inspections: $150 a year for each place of public assembly such as a restaurant or store, $75 per unit every three years for tenant spaces and apartment buildings with three or more units, and $25 for a reinspection. Signs are $2.50 per square foot (pylon refacing $75, a new pylon $125), and a site development plan is $125 for the first acre plus $75 for each additional acre.
For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.
What comes before the building permit
- Planning Commission site plan approval ($350 application, $350 final) and special use permits ($500).
- Zoning Board of Appeals variances: $250 for developed property, $500 for undeveloped land; a change of zone is $1,000.
- Highway work: any construction or disturbance in a town or county right-of-way needs that highway department’s permit; a full road cut is $750.
- Sewer and water: new sewer connections are $750 per dwelling unit inside a district; a water service permit is $75; percolation tests are $35 per lot.
- Flood zones: Rotterdam participates in the National Flood Insurance Program; its current flood map is dated January 8, 2014.
- Water and sewer outside a district: a new sewer connection costs $1,000 for three bedrooms or fewer plus $250 per extra bedroom, and a one-inch water tap installed by the Water Department is $1,100 plus $4 per foot on the same side of the street or $1,500 plus $4 per foot across it.
- Parkland and stormwater: residential development outside a subdivision pays $1,000 per dwelling unit in lieu of parkland, and the town charges a $100 stormwater inspection fee.
- Before digging: the handout reminds owners to call Dig Safely New York at 1-800-962-7962.

| Renewal before expiry / after expiry | $50 or 20%, whichever is higher / 50% of the original fee |
| Stop-work order (no valid permit) | Twice the permit cost plus $500 per placard |

For example, a new 2,200 sq ft house is $500 plus 1,200 × $0.40, or $980, and a detached 200 sq ft garage is $75 plus 100 × $0.60, or $135. Residential handicap ramps and doorways are exempt from the accessory-building fee. The alteration row gives two methods without saying which governs: on a $10,000 renovation, $50 plus 9 × $25 is $275, while $2.50 per $100 of the whole cost is $250, so ask the inspectors which they charge.

Electrical. Electrical work in Rotterdam needs a separate third-party electrical permit, and the Building Department does not inspect wiring; it gives final approval once the agency has. The town’s approved agencies are Middle Department Inspection Agency (518-273-0861), The Inspector, LLC (518-481-5300), Commonwealth Electrical Inspection Service (518-755-0324) and NY Atlantic-Inland (518-857-6235 or 607-753-7118). Every electrical inspection must be done before work moves on to the next stage.
Plumbing. The town issues its own plumbing permits. Under Chapter 213 the permit is taken out by the owner or the agent doing the plumbing, and the Plumbing Inspector inspects the work and issues a certificate of compliance. The fee is $75 for one to three fixtures and $10 for each added fixture; underground lawn sprinklers are also plumbing permits. The town code and forms show no plumber or contractor license; what they require is current liability and workers’ compensation insurance.
Septic and wells. Schenectady County issues engineering plan approvals and construction permits for septic systems, and the town application accepts county or town approval for a new system; the town’s septic permit fee is $150. A private well needs the town Well Regulation Form, a certified lab test and a $25 well permit renewed every three years.

Review, corrections and what causes delay
Residential plan review can take up to 20 business days, depending on how many projects are in the queue, and commercial review about 10 to 20. Incomplete applications and missing information are the main delays named by the town, along with insurance certificates that are out of date. Work must start within six months of issue and the permit expires after 12 months; renewing before it lapses costs $50 or 20% of the fee, whichever is higher, and an expired permit costs half the original fee to renew.
Rotterdam inspections and certificates
The contractor or owner must call 518-355-7575 ext. 395 at least 24 hours before each inspection; exact times cannot be guaranteed. The stages are footing forms with steel before the pour, the formed foundation, damp-proofing and bracing before backfill, slab preparation with vapor barrier, an approved foundation location before framing on new construction, framing with the truss certification, rough plumbing, heating, electrical and air sealing, insulation before interior finishes, and a final with as-built drawings. Water and sewer inspections are done by the Department of Public Works.

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
