Newton limits building lot coverage to 20-35% and total impervious surface to 40-50% depending on zoning district. SR1 has the most restrictive coverage at 20% building footprint.
Newton Zoning Chapter 30 regulates both building coverage (footprint) and total impervious surface coverage on each lot. SR1 caps building coverage at 20% with total impervious limited to 40%. SR2 allows 25% building and 45% impervious. SR3 and MR1 allow up to 35% building coverage with 50% impervious. Coverage includes principal structures, accessory buildings, decks over 18 inches tall, covered porches, and pools. Impervious surface also includes driveways, patios, walkways, and any non-permeable hardscape. Lots exceeding FAR (Floor Area Ratio) or coverage limits trigger Special Permit Design Review. Permeable pavers are credited at 50% toward impervious calculations in most districts.
