Pass North Castle’s RPRC, Insurance and Plan Review Gates Before Construction Begins
North Castle does not use one universal online permit portal. Only specified electrical, plumbing, HVAC and limited residential permits can be submitted by email; most larger applications follow the town’s two-set paper submission process.
This guide separates those routes, explains when Planning or RPRC approval comes first, calculates the verified 2026 permit fee, prepares the Westchester County license and insurance package, and shows how to request inspections and obtain the final Certificate of Occupancy or Compliance.

Screen RPRC and Planning Approval Before Filing the Building Permit
Interior-only renovation
The RPRC procedures exclude applications relating only to interior alterations or renovations.
Exterior residential work
The current residential application warns that work outside the residence generally requires RPRC approval unless it is minor and qualifies under the town’s gross-land-coverage exception.
Mandatory site-plan route
The Building Department states that a residential addition over 1,500 square feet, a teardown or a new structure requires site-plan approval.
RPRC decision |
North Castle rule |
Practical action |
|---|---|---|
One-time gross land coverage exception |
Up to 250 square feet for a one- or two-family dwelling when no wetland or steep-slope disturbance permit is required |
Use the RPRC exemption application and provide calculations. |
One-time gross floor area exception |
Up to a 10% expansion under the conditions in §355-26.B(2) |
Confirm eligibility and whether a wetland or steep-slope permit triggers Planning Board review. |
Standard RPRC submission |
One coordinated PDF with application, checklist, floor/land coverage worksheets and project plans |
Email the complete package to planning@northcastleny.com. |
Planning Board referral |
More complex projects, site plans, wetlands and other impacts can be referred to the appropriate board |
Do not file the building permit until the required Planning approval is granted. |

Describe the complete project
Include interior work, exterior work, site disturbance, fill, rock chipping, tree removal, plumbing, electrical, HVAC and any change of use.
Complete the preliminary zoning and Planning screen
Call Building or Planning before preparing the final submission. Determine whether RPRC, ARB, ZBA, Conservation Board or Planning Board approval is required.

For non-email applications, submit the completed and notarized application, fees, insurance, licenses, specifications, code-review forms and two complete plan sets.
Pass the completeness and plan review

Wetlands and buffers
The administrative wetland application starts with three plan sets showing existing conditions, two-foot contours, wells, septic systems, structures, disturbance limits and proposed mitigation.
Tree removal
Regulated tree removal can require a permit based on tree size, location, number of trees, wetland or conservation status and right-of-way location.
Fill and grading
The building applications ask about imported fill over 50 yards and certain bank-run or construction material quantities over 250 yards.

Application, RPRC, Fee, Inspection and Record Questions
Where is the North Castle Building Department located?
The Building Department is at 17 Bedford Road in the Town Hall Annex rear building in Armonk, New York. The telephone number is 914-273-3000, extension 44.
Can every North Castle permit be submitted online or by email?
No. Email filing is limited to the applications listed by the town: accepted electrical applications, plumbing, HVAC and certain residential permits such as roofs, siding, replacement windows, boilers, oil tanks, kitchens and bathrooms. Larger and specialty applications generally use the town’s paper and plan-set process.
What must be included with an emailed permit application?
Include the completed application, notarization when the applicant is not the owner, liability insurance, separate workers’ compensation and disability forms, the contractor’s Westchester County license and all required drawings and specifications. HVAC submissions also require Manual J and Manual S calculations.
How much is a North Castle residential building permit?
The current residential formula is a $125 application fee, $100 Certificate of Occupancy or Compliance fee and $16 for each $1,000 of construction cost, rounded up to the next $1,000. RPRC, Planning, trade, environmental and other fees are separate.
How much is a North Castle commercial building permit?
The current commercial formula is a $200 application fee, $250 Certificate of Occupancy or Compliance fee and $20 for each $1,000 of construction cost, rounded up to the next $1,000.
How long does North Castle plan review take?
The town’s stated target for an initial plan review is two to four weeks. Rereviews may take about two weeks. These are goals rather than guarantees and can be extended by workload, incomplete documents or outside-department review.
When should I request a North Castle building inspection?
Call the Building Department at 914-273-3000, extension 44, the business day before the requested weekday inspection. Keep the approved plans available at the project during every inspection.
When does a North Castle building permit expire?
A building permit becomes invalid if work does not begin within 12 months and expires 24 months after issuance. An invalid or expired permit may be renewed by the permit holder with an application, fee and Building Department approval.
Does my residential project need RPRC approval?
Interior-only alterations are generally excluded from RPRC review. Exterior residential work should be screened by Planning unless it qualifies for a current exemption. Residential additions over 1,500 square feet, teardowns and new structures require site-plan approval.
How do I obtain old North Castle permits and Certificates of Occupancy?
Use the Town of North Castle NextRequest FOIL portal. The town FAQ directs users to request the building file online, after which the file can be provided electronically. Ask specifically for applications, approved plans, inspections, violations, COs, CCs and temporary certificates.
