Can I Sell Part of My Property and Keep My House?

When you sell off a portion of your land, both the parcel you sell and the parcel you keep must comply with your town's zoning requirements — minimum lot size, minimum frontage, setbacks, and other dimensional standards. You cannot create a new lot that meets zoning minimums if doing so leaves your remaining lot undersized or non-conforming.

This is one of the most common constraints on partial land sales. A landowner with a five-acre lot in a two-acre zoning district may be able to sell off one lot — but only if both the new lot and the remaining lot each meet the two-acre minimum and all other dimensional requirements.

If the portion you want to sell has adequate frontage on an existing public road and meets all zoning requirements, it may qualify for an Approval Not Required (ANR) endorsement — a relatively simple process that does not require a public hearing. If a new road is needed, or if the lot doesn't have adequate frontage, a Definitive Subdivision approval is required.

ANR plans are typically faster and less expensive than Definitive Subdivisions, but they are only available when the new lot already has adequate frontage. A surveyor and often an attorney are needed to prepare and file the plan.

If the portion you want to sell includes or is adjacent to wetlands, the Conservation Commission may need to be involved. And if the new lot will need its own septic system, soil testing is required to confirm that the lot can support one.

Your existing house's septic system must also continue to comply with Title 5 after the lot line change — you cannot inadvertently create a setback violation by moving a property line closer to your existing system.

MA Land Pros can review your property's zoning, lot dimensions, and publicly available information to give you a realistic preliminary picture of whether a partial sale is feasible — and what steps would be needed to make it happen.
