Rochester-specific permitting context

New York has no statewide general-contractor license, so electrical work in the city must be performed by an electrician licensed through the City of Rochester's Electrical Examining Board, not a state credential. Older housing stock also triggers the city's Lead-Based Paint (Certificate of Occupancy) inspection program on many rentals.

Climate factors: Cold humid-continental climate with heavy lake-effect snow off Lake Ontario, high ground snow loads, and repeated freeze-thaw cycles that drive deep frost footings and roof-load design.

New York licensing for Home Addition contractors

No statewide GC license; NYC, Suffolk, Nassau, Westchester have local licensing - no statewide license, but Rochester likely requires local registration.

Mechanics lien deadline in New York: 8 months from last work (residential); 4 months (commercial). Preliminary notice: Not required separately.

Rochester Home Addition sales tax

New York sales tax: 4% + local (~8.5% combined avg). CAPITAL IMPROVEMENT to real property exempt (Form ST-124). REPAIR, MAINTENANCE, INSTALLATION labor on TPP taxable.
