Minimum Lot Sizes and Subdivision Procedure
Lot-size minima, frontage, and dimensional controls are set out primarily in the City of Boston zoning rules and associated planning regulations. The BPDA and ISD interpret those dimensional standards during review of subdivision plans and related permits. State subdivision control law also sets procedural rules for approval, plan endorsement, and filing that affect municipalities including Boston. Massachusetts General Laws, Chapter 41[3]
- Prepare a surveyed subdivision plan showing lot lines, dimensions, easements, and existing structures.
- Confirm zoning district minimum lot area and frontage in the City zoning maps and code.
- Schedule a pre-application meeting with BPDA or ISD to discuss submission requirements.
- Determine if the split is Approval Not Required (ANR) under state law or requires formal subdivision approval by city authorities.
