Zoning, building permits and septic rules in Town of Peru, Massachusetts

Town of Peru’s own rules

• Certificate of occupancyRequired

  Any building or structure erected, altered or relocated in Peru town, and any change of use of a building or premises there

  • Issued by the Inspector of Buildings of the Town of Peru.
  • Not granted unless the proposed use complies with the by-law, and no use may be made except the use authorized by the permit.
  • Also applies to impounding water behind a dam designed to impound more than 1,000,000 gallons (per section 15 text).

  “such permit shall not be granted unless the proposed use of the land or building complies in all respects with this by-law and no use shall be made except the use authorized by such occupancy permit.”

• Local zoningPresent (with conditions)

  Land inside Peru town limits (Berkshire County, MA). Peru administers its own zoning by-law; the text opened is the July 26, 2011 digital copy.

  • Only the 2011 digital copy was opened. Peru Planning Board notices from December 2025 through April 2026 show a revised zoning by-law in draft (including accessory dwelling units, short-term rentals, mobile/temporary home provisions and residential battery storage), so the in-force text must be confirmed before relying on it.
  • This is the town's own by-law, not a county or state rule.

  “the entire town shall constitute a single residential-agricultural zoning district.”

• Zoning districtsPublished (with conditions)

  Land inside Peru town limits: single zoning district covering the whole town.

  • The entire town is one residential-agricultural district in the text opened; no agricultural or rural-residential district separate from it was found in that text.
  • Based on the 2011 digital copy; the draft revision may change districts.

  “the entire town shall constitute a single residential-agricultural zoning district.”

• SetbacksSpecified

  Structures inside Peru town (single residential-agricultural district)

  • Applies to the whole town because it is the only district (Section 2).
  • The state-highway setback is measured from the center line of the travelled way, per the text of Section 8.2.
  • Setbacks follow the bylaw's own cross-reference to section 3.3b for private and public ways.

  front setback from public or private way: >= 65 feet · front setback from state numbered highway: >= 75 feet · side and rear setback: >= 20 feet

  “the minimum set-back for any structure shall be sixty-five (65) feet from public ways or private ways pursuant to 3.3b of this by-law and seventy-five (75) feet from state numbered highways to be measured from the center line of the travelled way. the minimum side-yard and rear-yard set-backs are twenty (20) feet.”
