Clarkstown permit action guide

Walk Into Room 101 With the Right Plot Plans, Construction Drawings and County-Licensed Contractors

Clarkstown’s official process is different from the online portal described on many third-party pages. The Town directs permit applicants to the Building Department in Room 101 at Town Hall and tells applicants to call ahead to confirm the documents required for the exact project.

This guide turns that process into clear actions: confirm Town-versus-village jurisdiction, prepare three zoning plot plans and two construction-plan sets when required, calculate the published base building fee, coordinate Rockland County electrical and contractor licensing, request inspections and complete the Certificate of Occupancy file.

Important correction to the existing page The Town’s official Building pages list the department at 845-639-2100, with hours of 9:00 a.m.–5:00 p.m., Monday through Friday. They direct applicants to Room 101 at Town Hall rather than an eTRAKiT application portal.

Prepare the correct number of plans Clarkstown’s published permit checklist calls for three copies of the zoning plot plan and two sets of construction drawings. Call before printing because a specific project may require additional documents.
COUNTY
Town permit does not replace Rockland County licensing Electrical, plumbing, mechanical and home-improvement contractors may need Rockland County licenses. Electrical approval also comes from an approved third-party electrical inspection agency.

Town versus village

Confirm Which Building Department Controls the Property

Town hamlets commonly use Clarkstown

  • Bardonia
  • Central Nyack
  • Congers
  • Nanuet
  • New City
  • Rockland Lake
  • Valley Cottage
  • West Nyack

Incorporated-village address

Clarkstown also contains all of Upper Nyack and portions of Nyack and Spring Valley. Those villages have their own building-department listings.

  • Do not rely only on the postal city name.
  • Confirm the parcel’s municipal boundary.
  • Ask whether Town or village zoning controls the project.
  • File with the office that confirms jurisdiction.
New City, Nanuet, Congers and West Nyack are hamlets, not separate incorporated villages. A property within an incorporated village may use a different building department even though it is geographically inside the Town of Clarkstown.

In-person application workflow

Apply for a Clarkstown Building Permit in Eight Steps

Confirm Town jurisdiction

Determine whether the property is under the Town of Clarkstown or an incorporated village building department.

Call Building before designing the final package

Describe the exact project and ask which permit, survey, plot plan, construction drawings and outside approvals are required.

Official number: 845-639-2100.

Prepare the zoning plot plans

The Town’s published checklist calls for three copies of a plot plan drawn to scale.

Prepare two construction-plan sets

Plans should be drawn to scale and clearly show the work required for compliance with the New York State Uniform Code, Energy Code and Town requirements.

Complete the permit application

An owner, agent or contractor may apply. Make sure the scope, project cost, ownership and contractor information are accurate.

Submit in Room 101

Bring the complete package to the lower level of Clarkstown Town Hall at 10 Maple Avenue, New City.

Respond to zoning and code comments

Revise every affected drawing and provide any missing survey, contractor, electrical, plumbing or agency information.

Collect and display the permit placard

After approval, post the permit placard at the job site and keep the approved construction plans available throughout construction.

Enter the total estimated project cost to calculate the published base fee.

This is a planning estimate for the published building-permit formula. Sign permits, special permits, variances, C.O. fees, fire permits, county licenses, electrical inspections and other charges can be separate.

Electrical and plumbing

Understand the Town Permit and County-License Split

Electrical work

  • Electrical work is inspected by a Town-approved third-party electrical inspection agency.
  • The agency issues the final electrical certificate of approval.
  • Most electrical work must be performed by or supervised by a Rockland County-licensed electrician.
  • The electrician files an inspection application and provides a copy to the Building Department.
Limited homeowner exception: An owner-occupant of a single-family dwelling may apply through Rockland County to perform basic general wiring. The Town states this does not include pools, electrical services or new additions.

Plumbing work

  • A permit is required for new fixtures, water-supply lines, sanitary or storm drainage and vent lines.
  • An owner-occupant of a single-family dwelling may perform their own work after obtaining the required permit.
  • In other cases, plumbing must be performed by a Rockland County-licensed or registered plumber.
  • Only emergency repairs should occur before issuance, and the required permit must still be obtained.

Home-improvement contractor

Rockland County states that individuals performing home-improvement work must obtain a Home Improvement License under Chapter 286.

Mechanical contractor

Rockland County separately licenses plumbing, heating, air conditioning, sheet-metal and refrigeration contractors.

Verify before signing

Search the County’s licensed-business dashboard and ask about complaint history before paying a large deposit.

Historic property

Clarkstown states that special standards and reviews apply to designated landmarks and properties within historic areas.

Call Building before changing exterior materials or features.

Fence guidance

Clarkstown Does Not Require a Fence Permit—but Zoning Limits Still Apply

Solid fence or wall

The Building FAQ says solid fences and walls, individually or together, cannot exceed approximately 4½ feet along a residential lot line.

Other residential fence

The Town FAQ states that fences cannot exceed six feet along a lot line unless setback by two-thirds of their height.

Street intersection

Corner and intersection fencing must comply with the sight-distance requirements referenced in Town Code Section 250-6.

Confirm the exact fence design before installation. Height, opacity, corner visibility, retaining walls, pools, easements and homeowners-association rules can change the result.
Inspection workflow

Request the Correct Inspection Before Work Is Covered

Confirm the permit is issued

Display the permit placard and keep the approved plan set at the job site.

Call the Building Department

Use 845-639-2100 to confirm the inspection-request procedure, available date and required inspection stage.

Keep the work visible

Do not conceal framing, wiring, piping, insulation or structural connections before the required approval.

Electrical work must receive the required approval certificate from an approved electrical inspection agency.

Read every correction before rebooking

Correct all listed issues and confirm whether revised plans or additional documentation are required.

Foundation or footing

Keep forms, reinforcement, footing dimensions and setbacks visible before concrete placement.

Rough framing and trades

Coordinate framing, electrical, plumbing, mechanical and fire-stopping work before enclosure.

Complete all construction, trade approvals, testing reports, final survey and zoning or fire conditions.

Permit and property records

Find an Old Permit Without Relying on a Nonexistent Portal Link

Collect the correct property identifiers

Use the street address plus map, block and lot. These identifiers reduce mistakes involving similar addresses.

Call the Building Department first

Ask whether the permit, C.O. or inspection record can be located directly and what information staff needs.

Request the exact record

State the approximate year, permit type and documents needed: application, approved plans, inspection history, C.O. or violation record.

Use the Clarkstown FOIL Center

Create an account to submit the request, track its status and download responsive records.

Verify final status before buying or selling

A building-permit application or issued permit does not prove final inspection or legal occupancy.

Existing-page correction: Do not direct readers to a Clarkstown eTRAKiT portal unless the Town itself publishes a verified portal. The official Building pages reviewed direct applicants to Town Hall and the department phone.
