Quick Summary

  • Peabody uses the term "Family Accessory Living Area" (FALA) in its local zoning ordinance (Section 6.7), but state law now governs ADU rights.
  • Under state law (effective February 2, 2025), ADUs up to 900 sq ft or 50% of the principal dwelling are allowed by right -- no special permit required, despite the local ordinance still referencing special permits.
  • The local FALA ordinance imposed heavy restrictions (family-only occupancy, owner-occupancy, no detached units, 25% size cap, personal permits) -- most are now preempted by state law.
  • Attached, detached, and internal ADUs are all permitted under state law, overriding Peabody's local prohibition on detached units.
  • The local 1-bedroom limit may still apply but could be challenged as unreasonable.
