A conservation restriction in Massachusetts is a permanent legal agreement between a landowner and a qualified holder that removes specific development rights from a property while leaving the owner in title. The arrangement is governed by Massachusetts General Laws Chapter 184, Sections 31 through 33, and in exchange for the lost development potential it can deliver property tax reductions, a federal income tax deduction, a state tax credit, and estate tax savings. Every future owner of the land is bound by the same terms.
What a Conservation Restriction Actually Is
Under MGL Chapter 184, Section 31, a conservation restriction is a right to keep land predominantly in its natural, scenic, or open condition, or in agricultural, farming, or forest use. It can also allow public recreational use or forbid construction, dumping, tree removal, and 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 term restrictions, but in practice the Secretary of Energy and Environmental Affairs approves only perpetual ones, and the IRS requires perpetuity for the federal tax deduction. Almost every restriction recorded in Massachusetts runs forever.2Mass.gov. Conservation Restriction Review Program
The landowner is the Grantor. The Grantee must 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 are the most common holders.2Mass.gov. Conservation Restriction Review Program
You keep title and can sell the property. What you cannot do is sell it free of the restriction. It runs with the land, so the next owner, and the one after that, take title subject to the same limits.
What You Give Up and What You Keep
Restrictions are not all-or-nothing. The document spells out which rights are extinguished and which the landowner retains. Common reserved rights include farming, forestry, recreation, maintenance of existing buildings, limited agricultural structures, and sometimes a house lot set aside for a family member.3MassWoods. Land Conservation Options
The terms get tailored to the property’s conservation values. Land with prime agricultural soils might permit continued farming but prohibit subdivision. A forested parcel near a reservoir might focus on water quality and impervious surface limits. Expect several rounds of revision, because the holder, the state, and often the landowner’s attorney all weigh in on the language.
The Secretary of Energy and Environmental Affairs will only approve a restriction that serves a genuine public interest, meaning it protects identifiable conservation values: drinking water, wildlife habitat, productive farmland, forest land, scenic landscapes, or areas of cultural significance.4Mass.gov. Commonwealth Conservation Land Tax Credit (CLTC)
Public Access Is Not Required
A common worry is that a conservation restriction forces you to open the land to the public. It does not. The Secretary encourages public access but does not require it when other public benefits are present. The restriction typically grants the holder’s representatives entry rights for compliance inspections, and that does not extend to the general public unless the landowner agrees to it in the document.
One caveat if you plan to claim the federal deduction: if the stated conservation purpose is outdoor recreation or education, the IRS expects some public access tied to that purpose. Restrictions grounded in habitat protection or open-space preservation have more room to limit access when it would conflict with the conservation goals.5Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
How the Process Works
Finding a Holder and Documenting the Baseline
The first 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 the organizational capacity to monitor the property annually and enforce the terms indefinitely, and smaller trusts sometimes decline properties that would strain their resources.
Once a holder is on board, the parties prepare a Baseline Documentation Report. This is a catalog of the property’s existing condition in maps, narratives, and photographs, and it becomes the benchmark against which every future change is measured.6Mass.gov. EOEEA Restriction Baseline Documentation Report Specifications If someone argues years later that a shed was already there or a meadow was already cleared, the baseline report settles it. Annual monitoring by the holder then builds on that baseline.7Massachusetts Association of Conservation Commissions. Massachusetts Conservation Restriction Stewardship Manual
Municipal Approval
Before the state weighs in, the restriction needs local sign-off. In a town, the board of selectmen votes; in a city, the mayor and city council.8Massachusetts Land Trust Coalition. Conservation Restrictions – A Tool for the Landowner and for the Community Some municipalities move quickly. Others need several meetings.
State Review and Deadlines
After municipal approval, the complete package goes to the Division of Conservation Services within the Executive Office of Energy and Environmental Affairs. The Secretary reviews the restriction to confirm it meets legal standards and serves a 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 can face delays.2Mass.gov. Conservation Restriction Review Program
One sequencing point trips people up: do not finalize municipal votes or gather local signatures until the Division of Conservation Services gives formal notice to proceed. If the state asks for changes after the local vote, you may have to redo the local approval.
Recording
Once the Secretary signs off and the parties execute the document, the restriction is recorded at the Registry of Deeds for the county where the land sits. Recording places it in the chain of title, putting every future buyer, lender, or title examiner on notice. The restriction is effective from that point.
What It Costs Upfront
The landowner bears most of the initial costs. These usually include legal counsel for drafting and review, a boundary survey if the restricted area does not match an existing recorded description, a qualified appraisal for the IRS deduction, recording fees at the Registry of Deeds, and a stewardship contribution to the holding organization. The stewardship endowment funds the holder’s annual monitoring and any future enforcement.
Total costs vary widely with property size and complexity. Budget for appraisals alone running into the thousands, plus legal fees on top.
Tax Benefits
Local Property Tax
A recorded perpetual restriction directly affects local assessment. Under MGL Chapter 59, Section 11, land under a conservation restriction in perpetuity must be assessed as a separate parcel, and where a written agreement exists between the landowner and the municipality, the assessor is bound by its terms.9General 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 a real loss in market value.
Federal Income Tax Deduction
A donation that meets the requirements of IRC Section 170(h) generates a federal charitable contribution deduction equal to the difference between the property’s fair market value before the restriction and its value after, as determined by a qualified appraisal.5Office 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. It must also be entirely voluntary. A restriction imposed as a condition of zoning approval or a permit does not qualify.
For most taxpayers, the deduction is capped at 50% of adjusted gross income in the year of donation, with any unused portion carrying forward for up to 15 additional tax years. Qualifying farmers and ranchers, meaning those who earn more than half their gross income from farming, can deduct up to 100% of AGI with the same 15-year carryforward. To claim 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 over $5,000. The appraisal must be dated no earlier than 60 days before the donation 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 deductions often get challenged, so working with an appraiser experienced in before-and-after valuation matters.
Massachusetts Conservation Land Tax Credit
Massachusetts adds a state-level incentive through the Conservation Land Tax Credit. Landowners who donate a conservation restriction (or land outright) that permanently protects an important natural resource may receive a credit equal to 50% of the donation’s value, up to $75,000.4Mass.gov. Commonwealth Conservation Land Tax Credit (CLTC)
The program has a statewide annual cap of $2 million and operates first-come, first-served. Donors must apply to and be certified by the Executive Office of Energy and Environmental Affairs before completing the donation. Donors do not need to be Massachusetts residents. The credit is a dollar-for-dollar reduction of Massachusetts income tax, which makes it more valuable than a deduction of the same size, and it stacks with the federal deduction.
Estate Tax Exclusion
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, capped at $500,000. The cap is fixed and 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 drops 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 the pre-easement value qualifies for the full 40% exclusion. For families with land-rich, cash-poor estates, this can be what lets heirs keep the property instead of selling to pay the tax bill.
Why a Restriction Is Nearly Impossible to Undo
Conservation restrictions carry a layer of constitutional protection most landowners underestimate. Article 97 of the Massachusetts Constitution declares the conservation of natural resources a public purpose and establishes a right to the enjoyment of the 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. Even if the landowner, the holder, and the municipality all agree to release a restriction, they still need a supermajority of both chambers to approve it.11Mass.gov. Article 97 and An Act Preserving Open Space in the Commonwealth
Amendments that stop short of release still follow the full approval cycle, including the Secretary’s sign-off.2Mass.gov. Conservation Restriction Review Program Even minor changes can trigger Article 97 scrutiny if they reduce conservation protections, so consult legal counsel before starting any amendment.
What Happens if the Holder Disappears
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 holder, and the state attorney general has standing to petition a court to transfer the restriction. The restriction does not evaporate because the holder does.
Monitoring After Recording
Granting a restriction is not the end of the relationship. The holder is obligated to monitor the property regularly, at minimum once per year, and to keep documentation of each visit including updated photographs and reports.7Massachusetts Association of Conservation Commissions. Massachusetts Conservation Restriction Stewardship Manual Annual visits catch violations early, before a small encroachment turns into a major enforcement fight.
Most land trusts ask for a stewardship endowment contribution at the time of donation. The fund covers monitoring visits and builds a reserve for legal defense of the restriction. The amount varies by organization and property, and it should be part of the landowner’s planning from the start. Without adequate stewardship funding, even a well-intentioned holder can struggle to fulfill its enforcement obligations over the decades ahead.
