Building or Renovating a Home in Fort Langley

The Fort Langley Community Plan (Bylaw 2527, adopted October 26, 1987) describes the whole community as sitting on a rise, with the Salmon River and farms on Agricultural Land Reserve soil around it. The fort was built at its present site in 1839 and is now a National Historic Site, looking over the Fraser River from the escarpment. Glover Road is the main street. Drivers coming from the north cross the Bedford Channel on the Jacob Haldi Bridge, and from every other direction they arrive past farmland.

Single family houses cover most of the plan area. The plan calls the housing stock unusually mixed, from small cottages to homes with many bedrooms, and some buildings are more than 100 years old. It keeps the minimum lot at 930 m², and allows a lot of 90% of that size where the lots around it are already smaller. Those numbers come from the R-1E zone in Zoning Bylaw 2500: 930 m² of area, 22 m of frontage and 25 m of depth, with the 10% relaxation in Section 110.2 for a lot within 100 m of smaller existing lots.

We read the Township's open parcel data for the Fort Langley plan area on October 28, 2026. All 733 land parcels there that are zoned for detached houses are R-1E. Their median mapped size is 962 m², half of them fall between 899 m² and 1,215 m², and 312 are under 930 m². The plan says few new lots can still be created, and it links lot size to the ground a septic field needs. The Township calls its map data a general reference, so a BC Land Surveyor measures any lot before we design for it.

The plan says houses north of the railway tracks, and the commercial and institutional buildings, are on Township sanitary sewer. Their sewage is pumped through lift stations on Billy Brown Road and on Mavis Avenue, then along 96 Avenue to the Northwest Langley treatment plant. The rest of the community uses on-site septic systems. Water comes from Metro Vancouver through a connection at 201 Street and 96 Avenue in Walnut Grove, and a reservoir near 212 Street and 85 Avenue holds water for fire protection. In the parcel data, 713 of the 733 R-1E lots show Township water and 21 show Township sewer.

On a septic lot, the septic system often sets the limits of the project. A new house, an addition, or a basement finish that adds bedrooms brings a Registered Onsite Wastewater Practitioner (ROWP) into the permit, and the Township needs the ROWP's paperwork before it issues the permit. The plan adds that a Fort Langley system may need extra treatment to remove nitrogen. For new development on septic, it asks for a qualified professional's letter that the land can carry the system, and a Section 219 covenant on title that fixes the location of the main field and the reserve field.

The plan says most rain soaks into the sand and gravel under the village, so the Township has built only short lengths of storm pipe, and it asks building projects to supply their own drainage. For a new house, the Township also wants a stormwater plan sealed by a civil engineer before any fill arrives on the lot.

Section 104.5 of Zoning Bylaw 2500 sets a height rule for the mapped Fort Langley area: buildings up to 9 m, no more than two storeys, and no room above the second storey. A basement is left out of the storey count while the first floor stays less than 800 mm above the average grade around the house.

The R-1E zone sets the rest. All buildings together can cover 35% of the lot. With the driveway off the street, the house sits between 6.0 m and 7.5 m from the front lot line, at least 3.0 m from the rear and 1.2 m from each side. A house of 280 m² or more, garages and carports included, keeps its second storey to 80% of the first, and its first floor no more than 0.8 m above average grade on any side facing a street. On a 962 m² lot, 35% coverage is 336 m² of footprint for the house, garage and any accessory building, and the septic field and reserve field need their own open ground.

The Township allows up to four homes on a lot only when it is connected to both Township water and sewer, among other conditions. A Fort Langley lot on septic keeps the R-1E choice: one house with a secondary suite of up to 120 m², or one house plus one accessory dwelling unit, such as a garden suite, when the house has no suite. Our coach house and garden suite page covers that option in detail. Township data show 6 of the R-1E lots inside the Agricultural Land Reserve, where the Agricultural Land Commission's limits apply first.

The Township has two heritage conservation areas, Fort Langley and Murrayville. Fort Langley's protects the heritage character of downtown, shown on Map 2 of the community plan, and the same area is a mandatory development permit area. The commercial core runs along Glover Road from St. Andrews Street to the Jacob Haldi Bridge. In the Township's parcel data, 258 parcel records carry the Fort Langley heritage conservation area flag, and 16 of them are R-1E house lots.

Inside the area, the Township needs a heritage alteration permit before any demolition, subdivision or redevelopment, and it may need one for changes to a protected heritage building. The permit follows the development permit process, with one difference: Council issues every heritage alteration permit itself. Neighbours next to the site receive a notice inviting written comments. Once issued, the permit is filed at the Land Title Office and binds later owners, and it lapses if work has not substantially started within two years.

Three kinds of work go ahead without a heritage alteration permit when they follow the plan's design guidelines: façade work on an existing building, such as new siding, doors, windows, cornices or awnings; an addition under 50 m² (538 sq ft) that does not face a road other than a lane; and an addition of that size and position built in the style and materials of the existing building.

The plan's design guidelines are three short rules. Restore historic buildings in a way that suits their own period and style, keeping original forms, materials and details where possible. Design new buildings and infill to blend with the historic parts of the street. Avoid decorative styles that are out of place in how Fort Langley's buildings developed. The Fort Langley Building Façade Design Guidelines are a separate, non-binding document that Council can change by resolution. For buildings on the Township's Heritage Inventory, the plan prefers upgrading and reuse to demolition.

The plan says Fort Langley is surrounded by the floodplain of the Fraser and Salmon Rivers, and Map 13 of the Township's community plan shows the areas at risk. Its policy is to keep land that is likely to flood for parks, open space or farming where possible.

Where a home does go on low land, Section 105 of Zoning Bylaw 2500 applies. At Glover Road, where the Jacob Haldi Bridge meets the Bedford Channel, the Fraser River's designated flood level is 6.94 m (Geodetic Survey of Canada datum), so the flood construction level there is 7.54 m. The underside of a wooden floor, or the top of a slab, under living space must be at or above that height, and no furnace or other fixed equipment may sit below it. A house must also stand at least 30 m from the natural boundary of the Fraser or Salmon River, with its floor at least 3 m above the Salmon River's natural boundary.

The Township's Salmon River Dike Upgrades page describes a $5 million project to widen and raise the dike along the Fraser River where the Salmon River joins it. The flood levels in Section 105 are written into the bylaw itself, so we check them on every lot below the village rise, and a BC Land Surveyor certifies the site elevation before the permit is issued.

A renovation avoids several of these steps. Section 105 exempts a renovation with no addition, and an addition under 25% of the existing floor area, from the flood elevation rule. Inside the conservation area, façade work and small additions away from the road can skip the heritage alteration permit. For a house built before 1990, the Township's renovation guide says a hazardous materials survey and a WorkSafeBC Notice of Project may be needed, so we test before any wall is opened.

A second storey is the addition to check first, because the 9 m and two-storey limit stays in force, and a main floor raised 800 mm or more above grade turns the basement into a storey. See our pages on home additions in Langley and whole-home renovations in Langley for the rules that apply across the Township.
