Buying ALR Land in BC: What You Can and Cannot Do With Agricultural Property

Buying Agricultural Land Reserve land in B.C. does not give you a regular rural lot. You can farm it, live in one principal house of up to 500 square metres, and in many cases add one small extra dwelling. You cannot treat it as a subdivision play, a multi-house compound, or a commercial yard unless the Agricultural Land Commission (ALC) or the ALR Use Regulation specifically allows that use.

The ALR covers 4,612,364 hectares, about 4.9% of the province, according to the Provincial Agricultural Land Commission’s 2024-2025 annual report. In the Fraser Valley the overlay is far denser. About 75% of the Township of Langley sits in the ALR. About 33% of Surrey does. Local zoning never overrides those provincial rules.

The Commission is blunt about ownership. In its 2024-2025 annual report it states, “Anyone can own land in the ALR, and our legislation does not compel landowners to farm.” What the law does compel is how you use the dirt. Price an ALR listing in your home search only after you map the parcel, the house-size cap, and the farm-class tax rules.

What the Agricultural Land Reserve actually is

The ALR is a provincial land-use zone created in 1973. Agriculture is the priority use. Non-farm uses, extra houses, soil movement, and most subdivisions are regulated by the Agricultural Land Commission Act and the Agricultural Land Reserve Use Regulation.

You must satisfy both layers: the ALC rules and the municipal zoning bylaw. The ALC Act takes precedence if the two conflict. A Township RU zone or a Surrey A-1 zone that appears to allow a use still cannot authorize that use if the ALR Regulation does not.

The reverse is also true. Langley and Surrey can ban a use the Regulation would allow. A home-based business, a kennel, or a second dwelling that is legal under the ALC can still fail a local building permit.

Confirm ALR status on the Commission’s ALR Maps tool, not only on the title. The ALC warns that a title notation such as “THIS CERTIFICATE OF TITLE MAY BE AFFECTED BY THE AGRICULTURAL LAND COMMISSION ACT” is not definitive. Some titled parcels sit outside the Reserve. Some untitled-looking titles sit inside it.

What you can do on ALR land

Farming is the default. Growing crops, raising livestock, operating greenhouses, producing cannabis or mushrooms, running a nursery, and keeping forage or orchard land are farm uses. You do not apply to the ALC to farm.

Farming and farm buildings

Structures necessary for a farm use are designated as farm uses. That includes barns, greenhouses, livestock buildings, mushroom houses, driveways that serve the farm, and utilities that serve the farm. Local government can restrict those buildings. It cannot prohibit the farm use itself.

According to the ALC, common farm activities include vegetables, berries, grains, oil seeds, cattle, sheep, goats, horses, swine, poultry, ornamentals, tree fruits, nuts, and forage. Wineries, cideries, breweries, distilleries, and meaderies are also designated farm uses when they meet the Regulation. Pair any building plan with a buying process review that includes zoning, floodplain, and well or septic capacity, not only the ALC page.

A house and a second dwelling

One principal residence is allowed without an ALC application if the total floor area is 500 square metres or less, about 5,382 square feet. An attached garage or unenclosed carport of up to 42 square metres is excluded from that cap on the principal house.

One additional detached residence is allowed without an ALC application if there is only one existing residence when construction starts. On a parcel of 40 hectares or less, that extra dwelling is capped at 90 square metres, about 969 square feet. On a parcel larger than 40 hectares, the cap is 186 square metres, about 2,002 square feet.

Most Langley and Surrey ALR lots are well under 40 hectares. The extra dwelling you can add without the Commission is therefore the 90 square metre unit, not a second full-size house. The extra dwelling does not have to be farm-worker housing. Family or a tenant can occupy it if local bylaws allow.

A secondary suite is allowed only inside the principal residence, and only if the municipality permits suites. A detached coach house is an additional residence, not a suite. It must meet the 90 or 186 square metre test, plus Township or Surrey zoning.

Farm retail, processing, and agri-tourism

You can pack, store, and process farm products without an ALC application if the farm produces at least 50% of what is processed. You can sell at the farm gate without an application if at least 50% of what you sell is produced on that farm.

Agri-tourism is a farm use when the land has BC Assessment farm class, the activity is tied to the working farm, and you do not build permanent visitor facilities or parking lots. Farm tours, u-pick, harvest festivals, and a corn maze grown on the farm fit. Paintball, ATV tracks, and a stand-alone restaurant do not.

Gathering for an event is allowed on farm-class land up to 10 events per calendar year, each 24 hours or less, with no more than 150 people on site at once. Permanent event buildings are not part of that permission.

Tourist accommodation, the ALC term for a bed and breakfast, is allowed in up to four bedrooms inside the lawful principal residence where the owner lives. That use does not require farm class. Agri-tourism accommodation of up to 10 sleeping units requires farm class and a working agri-tourism operation. Langley and Surrey short-term rental bylaws and the provincial principal residence rule still apply on top.

What you cannot do on ALR land

The expensive mistakes are almost always residential or commercial, not agricultural. Buyers treat a 5-acre ALR parcel like a country estate they can split, pad with fill, and load with shops. The Regulation does not work that way.

Subdivision and exclusion

Most ALR subdivisions need ALC approval. A local minimum lot size in the zoning bylaw is not a green light. The Township of Langley Rural Plan sets an 8.0 hectare minimum in Agriculture/Countryside areas, and still subjects that number to the Commission. Surrey’s A-1 zone sets a 4 hectare minimum inside the ALR.

A few boundary changes are permitted without an application under the ALR General Regulation. Examples include consolidating parcels, drawing the lot line along the ALR boundary, fixing a building encroachment without creating extra lots, and limited farm-lot line adjustments of not more than four parcels of at least 1 hectare each. Those are farm-structure tools, not a path to two new house lots.

Private landowners generally cannot apply to exclude land from the ALR. Under section 29 of the Agricultural Land Commission Act, as amended in 2019, exclusion applications are limited to the Province, a local government, a First Nation government, or a prescribed public body. Do not underwrite a Langley or Surrey purchase on the hope that you will “take it out of the ALR.”

The Commission approved 56% of subdivision applications it decided in 2024-2025. That figure includes farm-oriented boundary work across the province. It is not a 56% chance that a Fraser Valley acreage will be carved into residential lots.

Extra houses and oversized homes

A principal house larger than 500 square metres is a non-adhering residential use. You need an ALC application, and approval is discretionary. Residences built before the February 22, 2019 rule change, or later houses the Commission already approved, are generally measured under the rules that applied at the time.

A third dwelling, an extra house larger than 90 or 186 square metres, or keeping the old house while you build the new one all require a Non-Adhering Residential Use application. For any extra residence beyond what the Regulation already allows, the Commission “must not grant permission for an additional residence unless the additional residence is necessary for a farm use.”

Fill for a principal residence is limited. You may place fill on up to 1,000 square metres, including the driveway and yard that serve a house of 500 square metres or less, without a Notice of Intent if the finished grade meets local floodproofing rules. Any fill for an additional residence needs a Notice of Intent. Construction waste, asphalt, glass, plastics, treated wood, and unchipped lumber are not permitted fill.

Non-farm businesses and fill

A storage yard, truck depot, contractor’s shop, industrial plant, or stand-alone restaurant is a non-farm use. It needs ALC approval unless a narrow exemption in the Regulation applies. Home-based businesses, some kennels, temporary sawmills, small aggregate extraction under 500 cubic metres, and passive recreation are permitted non-farm uses when they meet the Regulation and local bylaws.

You also cannot assume an existing shop, second dwelling, or fill pad is legal. The ALC’s buying-and-owning guidance is explicit: the presence of buildings or ongoing activities does not mean those uses comply. Budget a title review, a municipal file search, and an ALC portal search before you remove subjects.

ALR rules in Langley versus Surrey

The provincial caps are the same in both municipalities. The local overlay is not. That is why two 10-acre listings a few kilometres apart can support very different house and suite plans.

The Township has long held about half of Metro Vancouver’s farms and more unused but farmable ALR land than anywhere else in the Fraser Valley. Small parcels are the norm. An older Township agricultural-viability study found 73% of ALR parcels were smaller than 4 hectares and only 14% were larger than 8 hectares, with an average parcel of 5.5 hectares. That inventory is why a “we will subdivide later” story almost never survives a consult with current maps.

Surrey’s A-1 zone is written to protect land designated Agricultural in the Official Community Plan. Intensive agriculture is allowed only on ALR land. New lots inside the Reserve must be at least 4 hectares. Buildings and structures for several accessory rural uses are capped at 10% lot coverage. Floodplain and the Surrey Soil Conservation and Protection Bylaw add a second filter on fill.

The City of Langley is a different map. Its A1 zone exists, but the compact city grid holds little ALR compared with the Township. If the listing says “Langley” and shows a 5-acre field, you are almost always in the Township.

Farm class is not the same as ALR

ALR status does not automatically cut your property tax bill. Farm class is a BC Assessment classification. You apply for it. The ALR is a land-use zone. You can own ALR land, live in the house, and still pay residential rates on the land if you never qualify as a farm.

Gross farm income thresholds under the Classification of Land as a Farm Regulation are:

•       Under 0.8 hectares (about 2 acres): $10,000 a year from qualifying primary production.

•       0.8 to 4 hectares (about 2 to 10 acres): $2,500 a year.

•       More than 4 hectares: $2,500 plus 5% of the actual value of the farm area above 4 hectares.

Applications for the next assessment roll are due by October 31. For the 2027 roll, BC Assessment extended that deadline to November 2, 2026 because October 31 falls on a weekend. Late filings wait a full year.

Land in the ALR can still receive a school-tax reduction of up to 50% on the land value even when the property is vacant or used as a residence, as long as development is restricted. That exemption does not replace farm class, and it does not cut municipal tax. The house itself is assessed as residential either way.

Farm class also unlocks several ALR side uses, including agri-tourism and on-farm events. If your financing plan depends on a farm-gate stand or weekend events, confirm farm class in the same week you confirm the mortgage product. A residential mortgage on a hobby acreage and a farm operating loan are not the same file.

How to check a parcel before you offer

Treat every ALR offer like a land-use file, not only a house file. Run these checks while the listing is still subject to inspection and financing.

•       Open the ALC ALR Maps tool and confirm whether the whole parcel, or only part of it, is in the Reserve.

•       Read the title for the ALC notation, then treat that notation as a clue, not proof.

•       Measure the existing house against the 500 square metre rule, including enclosed porches and excluding only the allowed 42 square metre garage.

•       Count dwellings. A suite inside the house is not the same as a cottage, mobile home, or converted shop.

•       Search the ALC application portal for past non-farm use, fill, subdivision, or non-adhering residential use files on the legal description.

•       Ask the municipality for building permits, occupancy, suite records, and soil-deposit files.

•       Ask BC Assessment whether the land is class 9 farm, class 1 residential, or split-classified.

•       Walk the ditches, floodplain, and neighbouring barns. The Farm Practices Protection (Right to Farm) Act protects normal farm noise, dust, and odour.

First-time buyers who want a house with a field attached should compare an ALR acreage against a regular rural or suburban lot before they spend the deposit. The first-time home buyer path still works on ALR land. The land-use constraints do not disappear because the kitchen is new.

When the intended use is a family home plus a small extra dwelling and some berries or horses, ALR land can be the right buy. When the intended use is three houses, a shop yard, or a future 10-lot bare-land strata, it is the wrong title.

FAQ

Can I buy ALR land in B.C. if I do not want to farm?

Yes. Anyone can own ALR land, and the Agricultural Land Commission Act does not force you to farm. You still cannot use the land for a non-farm business, extra houses, or a subdivision just because farming is optional. Neighbours who do farm keep their Right to Farm protections.

How big a house can I build on ALR land?

The provincial cap on a new principal residence is 500 square metres of total floor area, about 5,382 square feet, plus an attached garage of up to 42 square metres. Local zoning, floodplain, and setbacks can force a smaller house. Anything over 500 square metres needs a Non-Adhering Residential Use application to the ALC.

Can I put a second home or a coach house on a Langley or Surrey ALR lot?

Often yes, if the lot currently has only one residence and the new detached dwelling is 90 square metres or less on a parcel of 40 hectares or less. Local zoning must also allow that second unit. A third dwelling, or a second full-size house, needs ALC approval and must be necessary for a farm use.

Does ALR land automatically get farm-class property taxes?

No. Farm class is a separate BC Assessment application with income tests of $2,500 to $10,000 or more, depending on acreage. ALR land can receive a school-tax reduction of up to 50% on the land value even without farm class. Municipal tax and the house assessment stay on the residential track until farm class is granted.

Can I subdivide a 10-acre ALR parcel in the Township of Langley?

Not as a routine residential split. The Rural Plan uses an 8 hectare minimum in Agriculture/Countryside, 73% of Township ALR parcels are already under 4 hectares, and the ALC must still approve almost every new lot. Buy the property for the farm and the house that exist today.

Can I take my Surrey or Langley property out of the ALR?

Not by filing a private exclusion application. Since the 2019 amendments, only the Province, a local government, a First Nation government, or a prescribed public body can apply to exclude land. Plan as if the ALR line on the map is permanent.
