North Castle generally requires permits for new construction, additions, structural alterations, demolition, and work regulated by the New York State Uniform Code or Energy Code. Some projects also require separate trade or land-use approvals.

For decks, fences, retaining walls, pools, generators and borderline repair projects, confirm the specific requirements with the Building Department before purchasing materials or beginning work. See North Castle Town Code, Chapter 127.

How to Apply for a Building Permit in Armonk

Use the following process for a typical North Castle building permit. The submission method changes according to the project: only the categories expressly listed on the Town’s online permitting page are accepted by email.

1. Check whether preliminary approval is required. Describe your project to the Building Department and confirm whether you need RPRC, Planning Board, Architectural Review Board, Zoning Board or other approvals before filing.
2. Download the correct permit application. Open the official building forms page and select the residential, commercial, plumbing, HVAC or other applicable form.
3. Prepare the supporting documents. Include the project description, construction drawings, required approvals, contractor license, insurance certificates and applicable fees. Standard paper building applications call for two sets of required documents.
4. Submit using the approved channel. Email only eligible applications to Permits@northcastleny.com. For other projects, coordinate delivery of the completed application packet with the Building Department.
5. Complete review and payment. Respond to plan-review corrections, obtain any outstanding approvals and pay the required fees. Do not begin regulated construction until the permit has been issued.
6. Arrange inspections and final approval. Follow the inspection stages listed on your permit card, keep approved plans available and obtain the applicable Certificate of Occupancy or Compliance after completion.

Documents to prepare before submitting

• Completed and signed application, including owner authorization or notarization when required.
• Project address, scope of work, estimated construction value and applicable parcel identification.
• Site survey, plans and specifications appropriate to the proposed work.
• Approved RPRC or Planning determination, where required.
• Contractor’s required Westchester County license and liability coverage.
• Workers’ compensation documentation such as CE-200, C-105.2 or SI-12, as applicable.
• Disability insurance documentation such as DB-120.1 or DB-155, or acceptable exemption documentation.
• Energy-code compliance documents, structural calculations or professional plans when applicable.

North Castle requires the Town to be identified as certificate holder on applicable insurance documents. Workers’ compensation and disability proof must use acceptable state forms rather than an ordinary ACORD insurance certificate. The Town’s forms page also states that the BP-1 form is no longer accepted and directs homeowners to CE-200 documentation.

Armonk Building Permit Fees for 2026

The following amounts come from the Town of North Castle’s published 2026 Building Department Master Fee Schedule.

Example: residential permit fee calculation

For a residential project with an accepted construction valuation of $20,000, the published valuation-based construction fee would be $320 ($16 × 20). Adding the $125 application fee and $100 residential certificate fee gives an illustrative $545, before any additional applicable charges.

The Town’s 2026 residential application directs applicants to round construction cost up to the nearest $1,000 when determining the construction permit fee. Project-specific approvals, additional trade permits and other required services can increase the total.

How to Schedule a Building Inspection

North Castle’s published permit guide instructs permit holders to request a construction inspection by calling 914-273-3000, ext. 44, the day before the desired weekday inspection. Confirm scheduling availability and any project-specific instructions when calling.

Typical inspection stages

• Footings, foundation and preparation before concrete placement.
• Framing and structural work.
• Rough electrical, plumbing and mechanical systems.
• Fire-resistance and fire-protection components, where applicable.
• Energy compliance, insulation and related components.
• Final construction inspection after completing the approved work.

Not every project requires every inspection. Your permit card and approved plans determine the required stages. Keep the approved plans on site, and do not conceal work that must remain exposed for inspection.

If an inspection fails, correct the cited deficiencies and arrange reinspection before covering the affected work. Town Code §127-5 also allows remote inspections at the inspector’s discretion when an equivalent level of review is possible; applicants should not assume remote inspection is automatically available.

Final Certificate of Occupancy or Compliance

After construction, obtain approvals from all applicable reviewing departments and complete the required final inspections. The Building Department then determines whether the project qualifies for a Certificate of Occupancy (CO) or Certificate of Compliance (CC).

For eligible unfinished projects, the Building Inspector may issue a Temporary Certificate of Occupancy at their discretion if the relevant portion can be occupied safely. Temporary approval is not guaranteed.

RPRC, Zoning and Other Local Approvals

A distinctive part of permitting in North Castle is the Residential Project Review Committee (RPRC). It screens residential work for environmental, zoning, coverage and planning issues before directing the project to the Building Department or an appropriate review board.

RPRC review generally includes exterior residential projects and can involve additions, pools, accessory structures, wetlands and steep-slope work. Projects involving only interior alterations or renovations are excluded from the RPRC process described by the Town.

How to obtain an RPRC determination

1. Visit the official RPRC Process page.
2. Complete the required application and checklist.
3. Prepare floor-area and gross-land-coverage worksheets, drawings and required supporting materials.
4. Combine the documents into the single PDF submission requested by the Planning Department.
5. Email the submission to planning@northcastleny.gov and follow the department’s fee instructions.
6. Review the issued determination letter and complete any required corrections or board approvals before proceeding with the building permit.

The Planning Department is reachable at 914-273-3000, ext. 43. RPRC and Planning fees are separate from building permit fees.

Projects in regulated wetlands, floodplains, steep slopes or properties with private wells and septic systems may need additional approvals, including review by the Town Engineer or Westchester County Department of Health. Property-specific zoning should be checked using the North Castle zoning information page.

Building Codes Applicable in 2026

North Castle administers the New York State Uniform Fire Prevention and Building Code and State Energy Conservation Construction Code, together with applicable local requirements.

The 2025 New York State Uniform Code and 2025 Energy Code became effective December 31, 2025. Building permit applications submitted in 2026 generally must comply with these updated provisions, subject to applicable legal exceptions and court orders.

The updated code family addresses residential and commercial construction, plumbing, mechanical systems, fuel gas, fire prevention, property maintenance, existing buildings and energy conservation.

2026 caution: Some older North Castle guidance still references the 2020 New York State codes. Use the newer 2025 code materials for current applications. New York State also reports a court-ordered suspension affecting certain 2025 fossil-fuel equipment restrictions; this does not suspend the entire code update.

Permit Expiration, Records and Code Complaints

How long does a North Castle building permit remain valid?

Under Town Code §127-4(I), a building permit becomes invalid if authorized work is not commenced within 12 months after issuance and expires 24 months after issuance. An expired or invalid permit may be renewed through an approved application and applicable fee.

How to request existing building files

For past permits, approved plans, certificates or property building records, North Castle directs applicants to its online Freedom of Information Law (FOIL) request system.

1. Open the Town’s FOIL information page.
2. Choose the online public records request form.
3. Identify the property address and request the specific permit, certificate or building-file records needed.
4. Follow the Town’s response instructions. Access may depend on applicable public-record disclosure rules.

Reporting unsafe work or property-maintenance problems

The Building Department handles code-enforcement and property-maintenance complaints. Visit the Building & Engineering department page and select the official Building Department Complaint Form. Describe the property address, concern and relevant facts as precisely as possible.
