SR-3: Suburban Residential

What the zone allows

Homes allowed

One of these, subject to the Agricultural Land Commission Act where it applies (s. 303.2): 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

Main uses

Homes, home occupations, hobby beekeeping, accessory buildings; farming only on land in the ALR

Smallest lot for a subdivision

1,765 m², 27.45 m wide, 30.5 m deep (s. 110.1)

Lot coverage

33%; accessory buildings not used for farming (accessory dwelling units aside) at most 80 m² of ground floor in all (s. 303.3)

Height limit

Main buildings 9 m; accessory buildings not used for farming 4.75 m; hoop or arch buildings 2 m (s. 303.5)

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, street side 4.5 m; smaller ones 0.6 m from the rear and sides (s. 303.4)

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.

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.

A bed and breakfast is part of the bylaw's farm use, which this zone allows only on land in the ALR; there, on the farm use's conditions (s. 102).

Short-term rental isn't a listed use in this zone. 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.
