Full Breakdown
§ 68-24G opens by declaring the Town Board's 'participation in the New York State Unified Solar Permit program,' explaining that rising demand for residential solar has pushed Islip to standardize and streamline the permitting process. ' Applicants use the Town's New York State Unified Solar Permit application, available from the Building Division or the Town's website, along with a submittal-requirements checklist that lists the documentation every application needs. Larger residential systems, above the 25kW threshold, fall outside this fast track and are instead reviewed under the Town's general permit process in § 68-24A through F -- action on application, approval in part, signature and conditions, and expiration/renewal -- which carries no fixed determination deadline. The 14-day clock is a real, numeric commitment specific to solar, not a generic 'permits are processed promptly' promise found elsewhere in the chapter.
Violations & Fines
Installing or operating a qualifying solar system without first obtaining the § 68-24G permit determination is treated as unpermitted construction under § 68-23A/§ 68-421 -- a violation punishable by a fine of up to $2,000 or imprisonment up to 15 days, with each day of continued noncompliance a separate offense, and exposure to a stop-work order from the Commissioner of Planning.
