SR-1: Suburban Residential

What the zone allows

Homes allowed

One of these, subject to the Agricultural Land Commission Act where it applies (s. 301.2): small-scale multi-unit housing, up to 4 homes (3 on a lot of 280 m² or less) where the lot meets the conditions below; or one house with either a secondary suite or one accessory dwelling unit, not both. Also a temporary mobile home for family or a farm employee, in the ALR on 8,094 m² or more, or outside it on 2.02 ha or more of farmed land not over the Hopington Aquifer (s. 301.3)

Main uses

Homes, farming (a bed and breakfast is part of it, on conditions), commercial greenhouses, a temporary mobile home, home occupations, parking of commercial vehicles (s. 108), accessory buildings

Exceptions (1)

Listed in s. 301.1 of the bylaw.

Smallest lot for a subdivision

3,716 m², 40 m wide, 55 m deep (s. 110.1)

Lot coverage

33%; accessory buildings not used for farming (accessory dwelling units aside) at most 135 m² of ground floor in all (s. 301.4)

Height limit

9 m; accessory buildings not used for farming 7.5 m (s. 301.6)

Setbacks

House and other main buildings: front 9.75 m, rear 7.5 m, sides 3 m, street side 4.5 m. Accessory buildings of 6 m² or more: front 9.75 m, rear and sides 1.5 m (3 m for one of 80 m² or more), street side 4.5 m; smaller ones 0.6 m from the rear and sides. Buildings for animals or poultry 15 m from every lot line; commercial greenhouses 30 m (s. 301.5)

Small-scale multi-unit housing (s. 102): up to 4 homes on one lot, attached or detached (3 on a lot of 280 m² or less), only where the lot is inside the Official Community Plan's urban containment boundary, under 4,050 m², on municipal sewer and water, not protected as heritage, outside the Willowbrook Transit-Oriented Area and not reached from an arterial road. A secondary suite may sit in one of these homes; that suites count toward the 4 is our reading. The bylaw sets no higher count near frequent bus stops. Which of these conditions a lot meets we don't check: ask the Township.

A secondary suite is a home inside a house (or a duplex or small-scale multi-unit building), at most 120 m², built to the BC Building Code; in the ALR it must also meet the Agricultural Land Commission's rules (s. 102). An accessory dwelling unit is a home in a building of its own on the lot, such as a coach house (a home above a detached garage); the zone allows one only where the house has no suite.

A temporary mobile home (s. 301.3), renewed yearly while the owner lives in the house: for a farm employee or a parent, child, grandparent, grandchild, brother or sister of the owner; in the ALR on a lot of 8,094 m² or more, outside it on 2.02 ha or more of farmed land not over the Hopington Aquifer, or, on medical grounds, with Council's approval; additions at most 24 m²; removed within 90 days once no longer needed.

Commercial greenhouses need a noise report, a stormwater plan and an engineer's well test before a building permit (s. 301.9).

Parking: one space per home, at least 2 on the lot (s. 107.3).

Home occupations (s. 104.3): the owner lives in the home; not in a secondary suite; on a lot of 1,011.7 m² or less everything stays inside the home; at most 50 m² in all, up to 4 people with at most one employee who lives elsewhere; no vehicle repair, manufacturing or outdoor storage. A licensed family day care for up to 8 children counts as one.

Along 0 Avenue, buildings stay 29.75 m from the Canada-U.S. border (s. 104.14).

A transition house run by a non-profit society for women and children leaving abuse is also allowed, on conditions (s. 104.16).

Short-term rental isn't a listed use in this zone. A bed and breakfast is part of the bylaw's farm use here (s. 102, agricultural use): at most 3 guest rooms in the house or an accessory building, one per lot, on a lot of 1.7 ha or more, with the owner living there, a business licence and the Agricultural Land Commission's permission; how that last condition applies outside the ALR is unclear. Ask the Township before renting a home by the night.

Uses the zone doesn't list aren't allowed, even where a general clause might seem to cover them (s. 101.4).

Site-specific exceptions listed in the bylaw by legal description can add or change uses for one property, and development permit areas, the ALR and building rules apply on top. Confirm with the Township of Langley's community development division before you buy or build.
