If you are looking at land in Montgomery County’s Agricultural Reserve, one document can matter as much as price, acreage, or zoning: the easement. That can feel intimidating, especially if you are buying, selling, or planning for the next generation and want clear answers before you make a move. The good news is that the basics are understandable, and once you know what to review, you can ask smarter questions and avoid expensive assumptions. Let’s dive in.
Why easements matter here
Montgomery County’s Agricultural Reserve is a major land-use policy area, covering 93,000 acres, or about one-third of the county, according to Montgomery County Agricultural Services. The county also states that the AR zone generally limits development to one house per 25 acres, and about 70,000 acres in the Reserve are already protected by permanent easements.
That scale is a big reason buyers and sellers need to pay close attention. In this part of Montgomery County, land value and future use are often shaped not only by zoning, but also by the exact restrictions recorded against the property.
Montgomery Planning describes the Reserve as a long-term effort to protect farmland, agriculture, open space, scenic landscape, and public water supply. Planning materials also note that it is an active working landscape with more than 500 farms, and county materials say it contributes about $282 million to the county economy while housing less than 2% of county households.

What a conservation easement means
In plain language, a conservation easement is a voluntary legal agreement that limits certain future uses of land. The Maryland Environmental Trust explains that the easement is recorded in county land records and stays with the property, which means it binds future owners too.
That does not mean you give up ownership. In many cases, you can still live on the property, farm it, sell it, or pass it on to family or other future owners. What changes is that some development rights have been given up, often including the ability to subdivide land or add homes beyond what the easement allows.
It also does not automatically mean the public can enter your land. Maryland Environmental Trust materials make clear that public access is not automatically created by a conservation easement.
What the deed controls
The most important takeaway is simple: the recorded easement language controls what is allowed. Easements are tailored to the property and the program involved, so two farms in the same area may have different rules.
The easement holder also plays an ongoing role. According to Maryland Environmental Trust stewardship guidance, if an owner is unsure whether a new structure, land-use change, or event is allowed, they should request an approval or interpretation before moving forward.
For buyers, that means you should never assume a barn, tenant house, event use, lot split, or other improvement is permitted just because the property is large. For sellers, it means good preparation starts with gathering the actual deed of easement and related records early.
Common easement programs in the Ag Reserve
Montgomery County says there are seven agricultural land preservation programs, and each places an easement on the property to prevent future commercial, residential, or industrial development. Some programs purchase development rights, while others offer tax-related benefits for eliminating development potential. A helpful starting point is the county’s agricultural preservation program page.
Here are a few of the program types you are most likely to hear about in the Agricultural Reserve.
TDR easements
Transferable Development Rights, or TDR, move residential development potential away from farmland and toward designated receiving areas. Montgomery Planning states that a TDR easement permanently limits the sending property to a maximum of one dwelling unit per 25 acres.
This tool is designed to help preserve farmland while directing growth elsewhere. If you are evaluating a parcel, you will want to know whether TDR rights have already been severed, sold, or restricted, because that can affect both value and future flexibility.
BLT restrictions
Building Lot Termination, or BLT, is even more restrictive in a key way. According to Montgomery Planning’s TDR and BLT information, BLT permanently retires an approved on-site waste disposal system tied to a lot, which helps reduce farmland fragmentation by removing a potential home site.
For a buyer, that can be a major practical point. A parcel may look like it has room for another house on paper, but a BLT restriction can remove that possibility.
County agricultural easements
The county-run Agricultural Easement Program uses a formula based on farm size, soil quality, road frontage, and location. Montgomery County says this program can often be processed in about 6 to 12 months because it does not depend on state approval.
That matters for landowners comparing timelines and options. If preserving land is part of your long-term plan, understanding how timing, compensation, and restrictions vary by program can shape the best next step.
State and federal programs
State and federal programs can also apply. The Maryland Agricultural Land Preservation Foundation buys agricultural preservation easements that permanently restrict development on qualifying farmland and woodland, and the state says applicants should begin with the local program administrator.
Maryland’s CREP permanent easement program serves a different purpose. It is aimed at protecting water quality and natural resources, is available only to landowners with an existing federal CREP or CRP contract, and states that no structures may be built on enrolled lands.
What buyers should ask first
If you are buying in or near the Agricultural Reserve, your first question should not be only, “What does zoning allow?” It should be, “What do the recorded easements and restrictions allow?”
A practical buyer checklist includes:
- Reviewing the actual deed of easement
- Confirming whether any TDR or BLT restrictions affect the property
- Asking whether farming can continue as currently operated
- Checking whether the owner can add another house, split a lot, or change use
- Confirming who must approve future structures or land-use changes
- Reviewing permit, septic, well, stormwater, and forest-conservation issues that may still apply
Montgomery County also notes that people buying or selling near farmland should expect normal farm operations, including noise, odors, dust, smoke, insects, machinery, manure, and unusual hours. That disclosure is part of the practical reality of purchasing in this working landscape, and the county requires sellers to provide its agricultural-zones disclosure before contract, as explained in the county Agricultural Services FAQ.
What sellers should prepare
If you are selling land in the Ag Reserve, clear documentation can save time and reduce friction during due diligence. Because easements are recorded and bind future owners, buyers often need more than a standard property summary.
A strong seller file may include:
- The recorded deed of easement
- Any related approvals, interpretations, or correspondence
- Information on active agricultural use or prior agricultural assessment
- Septic, well, or waste-disposal records, if relevant
- Permit history for major structures or improvements
- The required agricultural-zones disclosure
This kind of preparation supports cleaner negotiations. It also helps avoid last-minute surprises when a buyer, title company, or attorney discovers restrictions that were not fully understood at the start.
Taxes and closing issues to know
Tax treatment can be one of the most misunderstood parts of easement property. Maryland Environmental Trust says donated conservation easements may qualify for federal and state income tax deductions, reduced estate and inheritance taxes, and a 15-year state and local property tax exemption on unimproved land.
At the same time, tax rules are strict. The IRS has warned that conservation-easement deductions have been abused, which is one reason careful compliance, documentation, and appraisal work matter.
Montgomery County also states that agricultural transfer-tax treatment can depend on whether the land remains in agricultural use, how long it has been agriculturally assessed, whether it is under a perpetual easement, and how it is zoned. In short, transfer taxes and closing costs may turn on several facts at once, not just acreage.
Permits and approvals still matter
Even if a property is in agricultural use, you should not assume every project is permit-free. Montgomery County says agricultural structures used exclusively for agriculture can be exempt from a building permit, but other rules may still apply depending on the project.
That can include utility, well, septic, erosion and sediment control, stormwater, and forest-conservation requirements. If a property is in a state program such as MALPF, the state says questions should start with the local program administrator because local review is part of the approval process.
The practical lesson is simple: check before you build. That is especially important for barns, replacement structures, event-related improvements, or any proposed change in use.
The smartest due diligence step
For most buyers and sellers, the best next step is not guessing from a listing description or a tax record. It is reviewing the title work and the actual easement documents early, then matching those documents to your real-world goals for the property.
If you want to keep farming, preserve a family asset, buy a home site with acreage, or sell land with fewer surprises, document review is where clarity starts. In Montgomery County’s Agricultural Reserve, that upfront work often makes the difference between a smooth transaction and a frustrating one.
