Full Breakdown
Newton participates in the Massachusetts SolSmart and streamlined solar permitting program. Residential rooftop solar installations require a building permit (typically $75) and electrical permit ($75) through the Newton Inspectional Services Department, with plan review completed in 7-14 business days for standard installations. Structural engineering review is required for roofs over 20 years old or with existing structural concerns. Newton cannot prohibit rooftop solar under MGL Chapter 40A Section 3, which provides statewide solar access protection.
