Can You Build a Second Home on ALR Land in BC?
Some Agricultural Land Reserve properties can have an additional detached residence without an individual ALC approval. The answer depends on the parcel, the existing home, the proposed floor area and the local rules.
The short answer
- Section 34.3 of the ALR Use Regulation provides a route for one additional detached residence when all its conditions are met.
- Its additional-residence limit is 90 m² on parcels of 40 hectares or less, and 186 m² on parcels larger than 40 hectares, with conditions on the principal residence.
- Local zoning and other approvals still apply. Permission under one set of rules does not settle the others.
- Check the ALC floor-area definition and soil or fill requirements before choosing a design or ordering a manufactured home.
Start with the parcel and the existing residence
A listing that mentions two homes, a family cottage or room for a second dwelling needs a closer look. First establish whether the parcel is in the ALR and what approvals or lawful permissions apply to the buildings already there.
Use current ALC mapping to investigate ALR status. The ALC warns that a notation on title is not a definitive boundary check. Where only part of a parcel is in the reserve, establish where the proposed work would sit and ask for advice if the boundary is unclear.
The ALC's guidance for buyers also makes the relationship with zoning clear: a use must comply with ALR legislation as well as the applicable local rules. Municipal permission alone cannot authorize a use that ALR legislation does not permit.

The additional-residence route under section 34.3
Section 34.3 applies to an additional residence whose construction begins after December 30, 2021. At the start of construction, the parcel must have only one residence, which may contain a permitted secondary suite. The new residence must be separate from the other residence.
The size conditions depend on the parcel area. Read the table with the other conditions in the section; the size limit alone does not establish eligibility.
Exactly 40 hectares falls in the first row. A larger principal house or an existing second residence is a reason to investigate the property's particular approvals before relying on this route.
| Parcel area | Additional residence | Other residence |
|---|---|---|
| 40 hectares or less | Total floor area of 90 m² or less | Total floor area of 500 m² or less |
| More than 40 hectares | Total floor area of 186 m² or less | A size permitted under the ALC Act |
ALR Use Regulation: section 34.3
A secondary suite and a detached home are different proposals
A secondary suite is located inside the principal residence. An additional residence under the route above is detached. Label the intended arrangement clearly on the plan so the local government and ALC can assess the right category.
The ALC says a qualifying additional residence does not have to be occupied by farm help. Family members or others may occupy it, subject to the applicable rules. That statement does not establish permission for a particular rental or tourist accommodation use.
The ALC also uses specific floor-area definitions. Do not assume a manufacturer's advertised living area, or a municipal floor-area exclusion, gives the figure needed for the ALR test. Ask your designer to document the calculation using the current ALC definitions for the proposed residence.

A worked example: a 5-hectare parcel
Consider a hypothetical 5-hectare parcel with one existing 300 m² principal residence and a proposed detached 85 m² home. Assume these are the areas calculated under the applicable ALC definitions, and that construction timing and the remaining section 34.3 conditions are satisfied.
The parcel is in the 40-hectares-or-less band. The proposed 85 m² additional home and the existing 300 m² house are within that band's size conditions. Those calculations justify moving on to the local zoning, siting, servicing and soil-work checks.
Change the proposed additional home to 110 m² and it exceeds the 90 m² limit for that route. Having 5 hectares of land does not increase the limit proportionally. The options to investigate are a compliant smaller design or an application for the necessary approval.
Check the work needed to reach the house
Sketch the access, foundation area, service trenches and proposed soil movement alongside the building. An additional home can need work beyond its footprint, particularly if it is proposed far from the existing residence.
Soil removal and fill placement have their own ALR requirements. The ALC's soil-and-fill guidance explains when a Notice of Intent or another authorization may be required. Establish that route before scheduling excavation or deliveries.
A second home also does not establish permission to split off a new residential lot. The ALC treats subdivision separately and warns that local minimum parcel sizes do not guarantee its approval. If eventual separate ownership is the goal, investigate it at the beginning.

Prepare a property-specific enquiry
- Identify the legal parcel and ALR boundary. Record the PID and parcel area. Use current ALC mapping and seek confirmation where the status or proposed building location is uncertain.
- Document the existing buildings. Collect permits and any ALC decisions. Establish which residence is principal and whether another residence already exists.
- Test the proposed residence. Compare the configuration and documented floor areas with the applicable regulatory route, including the full conditions of section 34.3 where relevant.
- Confirm local requirements and site works. Ask about zoning, siting, servicing and permits. Identify soil and fill work and confirm whether ALC authorization is needed for that work.
For an initial screen, use ZoneScout to investigate the property's zone and available ALR information. Bring the parcel details and proposed layout to the local government and, where needed, the ALC so the enquiry addresses the actual home you intend to build.

Frequently asked questions
Can I build a second house on ALR land without applying to the ALC?
A qualifying additional residence can be permitted under section 34.3 of the ALR Use Regulation. Check all of its conditions, the existing residence, parcel area and local requirements. Soil or fill work may need a separate authorization.
Does the additional home have to be for farm workers?
The ALC says a qualifying additional residence does not need to be intended for farm help. Its occupancy and use must still comply with the applicable rules.
Can I buy a manufactured home based on its advertised size?
First have the proposed design checked against the applicable floor-area definition and other requirements. Advertised living area may not be the measurement required by the ALC or local government.
Can I sell the second home's land separately later?
Permission for an additional residence does not grant subdivision approval. Investigate the local and ALC subdivision requirements separately before relying on a future lot sale.
