Islip's Relaxed Approach to Solar Energy: What's Allowed

Every city handles solar energy a little differently. In Islip, New York, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Panel Permits

Islip uses the NY Unified Solar Permit for residential PV up to 25 kW — 375 dollar flat fee, expedited review. Ground-mount systems allowed in rear yard with setback compliance. NY-Sun incentives plus 25 percent state tax credit (max 5,000 dollars).

Key details: Permit: NY Unified Solar Permit. Fee: 375 dollars flat. State Credit: 25 percent up to 5,000 dollars. Utility: PSEG Long Island. HOA: Cannot ban (RPAPL 335-b).

Unpermitted install: 250 dollar fine plus required inspection; utility may refuse interconnection. Non-code electrical: failed inspection.

If you are coming from a city with tighter rules, you will find Islip gives residents more flexibility on panel permits.

HOA Restrictions

NY Real Property Actions and Proceedings Law §335-b (2022) prohibits HOAs from banning solar panels on owner-occupied roofs. HOAs may impose reasonable aesthetic rules (not effectively prohibitive). Islip condos must comply.

Key details: State Law: NY RPAPL 335-b (2022). Protected: Owner-occupied roofs. HOA Limit: No effective prohibition. Aesthetic Rules: Under 10 percent output loss. Remedy: Attorney fees recoverable.

HOA attempting to ban solar: void rule; homeowner may sue for declaratory judgment plus attorney fees. HOA fines for compliant installation: recoverable as damages.

Islip is more permissive than most cities when it comes to hoa restrictions. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Islip gives residents more room on solar energy. 2 of the 2 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Islip's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
