City of New York Municipal Solar-Readiness Assessment (Local Law 24 of 2016) data
These data were prepared in compliance with the requirements of Local Law 24 of 2016 (LL24). Under LL24, the Department of Citywide Administrative Services (DCAS) is required to assess the solar photovoltaic (PV) potential of all City-owned buildings over 10,000 gross square feet once every two years. Special focus is given to identifying and quantifying potential capacity at solar-ready buildings, which are defined as buildings that have roofs that are no more than 10 years old and are in fair or good condition. The 2022 Solar-Readiness Assessment is the fourth biennial assessment pursuant to LL24.
