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.

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.
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.
