A conservation restriction in Massachusetts is a permanent legal agreement that limits development on your land while you keep ownership of it. You grant specific rights (usually the right to subdivide, build, excavate, or clear) to a qualified holder such as a land trust or municipal conservation commission, and those limits bind every future owner of the property. In exchange, you can qualify for a reduced property tax assessment, a federal income tax deduction, a Massachusetts tax credit, and estate tax relief for your heirs. The tradeoff is real: once recorded, the restriction is extraordinarily difficult to undo.
What the Restriction Actually Is
Conservation restrictions are governed by Massachusetts General Laws Chapter 184, Sections 31 through 33. Section 31 defines the restriction as a right to keep land predominantly in its natural, scenic, or open condition, or in agricultural, farming, or forest use. It can also forbid construction, dumping, tree removal, or excavation that would alter the land’s character.1General Court of Massachusetts. Massachusetts Code Chapter 184 – General Provisions Relative to Real Property
The statute technically allows a restriction for a set term of years, but in practice the Secretary of Energy and Environmental Affairs only approves permanent ones. The IRS also requires perpetuity for the federal deduction. Virtually every restriction recorded in the state runs forever.2Mass.gov. Conservation Restriction Review Program
You, the landowner, are the Grantor. The Grantee has to be either a governmental body (such as a municipal conservation commission or water district) or a nonprofit whose purposes include conservation of land or water. Local land trusts hold most restrictions.2Mass.gov. Conservation Restriction Review Program
Think of it as a permanent negative easement. You keep title and can sell the land, but each subsequent buyer takes it subject to the same limits. The restriction runs with the land, not with you personally.
What You Keep and What You Give Up
Restrictions are not all-or-nothing. The document spells out exactly what rights you surrender and what you retain. Typical reserved rights include farming, forestry, and recreation. Some landowners also reserve the right to maintain existing buildings, construct limited agricultural structures, or set aside a house lot for a family member.3MassWoods. Land Conservation Options
Terms get tailored to the property’s conservation values. Land with prime agricultural soils might allow continued farming but prohibit subdivision. A forested parcel near a reservoir might focus on water quality and limit impervious surfaces. Expect multiple drafting rounds; the holding organization, the state, and your attorney will each have input.
Public Access Is Not Required
A common misconception is that granting a restriction forces you to open your land to the public. It doesn’t. The Secretary encourages public access, but it is not a condition of approval when other public benefits exist. The restriction document typically gives the holder’s representatives the right to enter for compliance checks, and that right does not extend to the general public unless you specifically grant it.
One wrinkle: if you claim a federal tax deduction and the stated conservation purpose is outdoor recreation or education, the IRS expects some level of public access tied to that purpose. Restrictions grounded in habitat protection or open-space preservation under governmental policy have more flexibility to limit access when it would conflict with the conservation goals.4Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
Finding a Holder and Building the Baseline
The first real step is identifying a qualified holder willing to take on the restriction. Most landowners approach a local or regional land trust, though a municipal conservation commission can also serve. The holder needs organizational capacity to monitor the property annually and enforce the terms indefinitely, so smaller trusts sometimes decline properties that would strain their resources.
Once a holder is on board, you work together on a Baseline Documentation Report. This catalogs the property’s existing condition through maps, narratives, and photographs, and sets the benchmark against which all future changes will be measured.5Mass.gov. EOEEA Restriction Baseline Documentation Report Specifications If a question comes up years later about whether a structure was already there or a meadow was already cleared, the baseline settles it. The holder’s annual monitoring builds from this record.6Massachusetts Association of Conservation Commissions. Massachusetts Conservation Restriction Stewardship Manual
Approval and Recording
Before the state weighs in, the restriction needs local sign-off. The board of selectmen (in a town) or the mayor and city council (in a city) must approve it.7Massachusetts Land Trust Coalition. Conservation Restrictions – A Tool for the Landowner and for the Community Some municipalities move quickly; others may take several meetings.
After municipal approval, the package goes to the Division of Conservation Services within the Executive Office of Energy and Environmental Affairs. The Secretary reviews the restriction for legal sufficiency and genuine public interest. Submission deadlines matter: draft restrictions must be submitted by February 1 for approval by the end of the fiscal year (June 30), or by October 1 for approval by the end of the calendar year (December 31). Late submissions may face delays.2Mass.gov. Conservation Restriction Review Program
One procedural note worth taking seriously: do not obtain local signatures or finalize municipal votes until the Division of Conservation Services gives formal notice to proceed. Jumping ahead creates problems if the state later requests changes to the draft language.
Once the Secretary signs off and all parties execute the document, you record it at the Registry of Deeds for the county where the land sits. Recording places the restriction in the chain of title, putting every future buyer, lender, and title examiner on notice. The restriction is effective from that point forward.
What It Costs
You will typically bear most of the upfront costs. These include legal counsel for drafting and reviewing the restriction, a boundary survey if the restricted area doesn’t match an existing recorded description, the qualified appraisal needed for an IRS deduction, recording fees at the Registry of Deeds, and often a stewardship contribution to the holding organization. The stewardship endowment funds the holder’s annual monitoring and any future enforcement costs.
Totals range widely with the property’s size and complexity, but budget for appraisals alone running into the thousands, with legal fees on top.
Property Tax Treatment
A recorded perpetual restriction changes how your property gets assessed locally. Under MGL Chapter 59, Section 11, land under a perpetual conservation restriction must be assessed as a separate parcel. When a written agreement exists between you and the municipality, the assessor is bound by its terms.8General Court of Massachusetts. Massachusetts Code Chapter 59 – Real Estate – Section 11
Because the restriction eliminates development potential, the assessed value usually drops, sometimes substantially. A 50-acre parcel zoned for residential subdivision is worth far less once the right to build houses is permanently gone. The tax reduction reflects genuine lost market value.
This differs from Chapter 61 programs for forestry, agriculture, and recreation, which reduce assessments based on current use but impose rollback taxes if the land is later developed. A conservation restriction creates a permanent change, so there is no rollback. The development rights no longer exist to be reclaimed.
Federal Income Tax Deduction
Donating a restriction that meets IRC Section 170(h) generates a federal charitable contribution deduction. The deduction equals the difference between the property’s fair market value before the restriction and its value after, as determined by a qualified appraisal.4Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
To qualify, the restriction must be granted in perpetuity to a qualified organization and serve an exclusively conservation purpose. The contribution must be entirely voluntary. A restriction required as a condition of a zoning approval or permit does not qualify.
For most taxpayers, the deduction is capped at 50% of adjusted gross income in the donation year. Any unused portion carries forward for up to 15 additional tax years. Qualifying farmers and ranchers (those earning more than half their gross income from farming) can deduct up to 100% of AGI, also with a 15-year carryforward. To get the enhanced limit, the restriction must include a provision that the property remain available for agricultural use.
The IRS requires a qualified appraisal for any conservation easement deduction exceeding $5,000. The appraisal must be conducted no earlier than 60 days before the donation date and no later than the extended due date of the return claiming the deduction, and it must be prepared by a qualified appraiser and attached to the return. This is where many conservation easement deductions run into trouble. The IRS has aggressively challenged appraisals it considers inflated, so working with an experienced appraiser who understands before-and-after valuation is worth the cost.
Massachusetts Conservation Land Tax Credit
Massachusetts offers a separate state incentive through the Conservation Land Tax Credit. If you donate a restriction (or land outright) that permanently protects an important natural resource, you may receive a credit equal to 50% of the donation’s value, up to $75,000.9Mass.gov. Commonwealth Conservation Land Tax Credit (CLTC)
The program has a statewide annual cap of $2 million and operates first-come, first-served. All donors must apply to and be certified by the Executive Office of Energy and Environmental Affairs before making the donation.9Mass.gov. Commonwealth Conservation Land Tax Credit (CLTC)
The credit is a dollar-for-dollar reduction of Massachusetts income tax liability, which makes it more valuable than a deduction of the same amount. You do not need to be a Massachusetts resident to qualify. The credit also stacks with the federal charitable deduction, so a qualifying donation can produce both.
Estate Tax Benefits for Heirs
Restrictions can also reduce estate tax liability. Under IRC Section 2031(c), the executor of an estate can elect to exclude from the taxable estate up to 40% of the value of land subject to a qualifying conservation easement. The total exclusion is capped at $500,000, and that cap does not adjust for inflation.10Office of the Law Revision Counsel. 26 USC 2031 – Definition of Gross Estate
The applicable percentage starts at 40% and decreases by two percentage points for every percentage point the easement’s value falls below 30% of the unrestricted land value. A restriction worth at least 30% of pre-easement value qualifies for the full 40% exclusion. For families with land-rich, cash-poor estates, this can be the difference between heirs keeping the property and selling it to pay the tax bill.
After It’s Recorded
Granting a restriction is not a one-and-done event. The holder is obligated to monitor the property at minimum once per year and keep documentation of each visit, including updated photographs and reports.6Massachusetts Association of Conservation Commissions. Massachusetts Conservation Restriction Stewardship Manual Annual monitoring is how violations get caught early, before a small encroachment becomes a major enforcement battle.
Most land trusts ask for a stewardship contribution at the time of the donation to fund those annual visits and build a reserve for legal defense of the restriction. Amounts vary by organization and property. Without adequate stewardship funding, even a well-intentioned holder may struggle to fulfill its obligations decades out.
What Happens if the Holder Dissolves
A reasonable worry for anyone committing to a permanent restriction is what happens if the holding organization ceases to exist. The restriction survives. Under Section 32, enforcement rights can be assigned to any other governmental body or charitable organization with similar conservation purposes. Well-drafted restrictions often name a backup holder to step in automatically if the primary holder fails in its duties.
If no backup is named, a court can appoint a substitute. The state attorney general also has standing to intervene in cases involving conservation easements as charitable assets and can petition a court to transfer the restriction to a capable organization. The restriction does not simply evaporate because the holder disappears.
Article 97 Makes Changes Nearly Impossible
Massachusetts restrictions carry a layer of constitutional protection most landowners don’t fully appreciate until they try to modify one. Article 97 of the Massachusetts Constitution declares the conservation of natural resources a public purpose and establishes a right to the enjoyment of natural, scenic, historical, and aesthetic qualities of the environment.11Mass.gov. Article 97 and An Act Preserving Open Space in the Commonwealth
Land or easements protected under Article 97 cannot be converted to other uses or disposed of without a two-thirds roll call vote of the state legislature. That is an extraordinarily high bar. Even if you, the holder, and the municipality all agree to release a restriction, you still need a supermajority of both chambers to approve the change.11Mass.gov. Article 97 and An Act Preserving Open Space in the Commonwealth
Amendments that don’t amount to a release still go through the full review process. The parties submit the amendment to the Division of Conservation Services, and it moves through the same approval cycle as a new restriction, including the Secretary’s sign-off.2Mass.gov. Conservation Restriction Review Program Even seemingly minor changes can trigger Article 97 scrutiny if they reduce the conservation protections, so consult legal counsel before starting any amendment.
