Summary
Every solar installation in Mount Vernon needs a building permit before work starts, City Code § 224A-5. Larger, ground-mounted Tier 3 arrays also need a Planning Board special permit and site plan approval, which triggers state environmental review under 6 NYCRR Part 617.
A. A building permit shall be required for the installation of all solar energy systems. ... C. ... Issuance of approval by the Planning Board shall be subject to the requirements of the State Environmental Quality Review Act ("SEQRA") and its implementing regulations at 6 NYCRR Part 617.
Full Breakdown
Chapter 224A splits permitting into three tracks. Tier 1 (roof-mounted, building-integrated, canopy) and Tier 2 (small ground-mounted systems up to 25 kW, capped at 950 square feet and 15 feet tall, side or rear yard only) both use the New York State Unified Solar Permit through the Building Department and are exempt from Planning Board and Architectural Review Board review (§§ 224A-6, 224A-7). Tier 3, everything larger, including ground arrays over 25 kW and community solar facilities where 75% or more of the output goes off-site, requires a special permit and site plan approval from the Planning Board under Chapter 267, Articles VI and VII, with an 8-acre minimum lot size, a 25-foot/two-story height cap, mandatory underground utility lines, and a limit of 30% tree removal on site (§ 224A-8).
Because Tier 3 approval runs through the Planning Board, § 224A-5C brings it under the State Environmental Quality Review Act and its implementing regulations at 6 NYCRR Part 617, a review step the smaller tiers never trigger. All systems, regardless of tier, must also meet the NYS Uniform Fire Prevention and Building Code and the NYS Energy Conservation Code (§ 224A-4). A modification that grows an existing system's footprint by more than 5% resets it back into full review under whichever tier now applies.
Violations & Fines
Chapter 224A does not carry its own fine schedule for skipping the permit step. An installation built without the required building permit, Unified Solar Permit, standard permit, or Tier 3 special permit and site plan, falls back on the Code's general penalty, § 1-4: a fine up to $250 (up to $500 for a corporation) or up to 15 days in jail, and the Building Department can issue a stop-work order.
