The City of Langley and the Township of Langley are separate local governments with separate zoning bylaws. A coach house that is straightforward on one side of the boundary can be governed by entirely different height and siting rules on the other. Almost every guide written about "Langley" quietly picks one and ignores the other.
Langley City's Zoning Bylaw, 2025, No. 3300 (in effect March 9, 2026) permits a garden suite — the lesser of one storey or 4.6 m — or a carriage home — the lesser of two storeys or 6.8 m — each up to 100 m2 gross ground floor area, on R1 lots. R1 now covers nearly all former single-detached lots, because Bylaw 3300 converted every RS1 and RS2 lot to R1. The registered owner must live on the lot. Inside the City's Transit-Oriented Areas an R1 lot gets ONE accessory unit (secondary suite, garden suite OR carriage home) and no plex. This is a different rulebook from Langley Township's.

The Township of Langley is a separate government from Langley City, with its own Zoning Bylaw 1987 No. 2500 (SSMUH amendments adopted November 18, 2024). Most R-1A to R-1E, R-CL-family and R-2 lots allow one detached accessory dwelling unit — but ONLY where the house has no secondary suite — up to 9 m in height, with no floor-area cap and no owner-occupancy requirement. Suburban Residential (SR) zones carry the same one-ADU path (SR is suburban, not rural). The rural RU zones have NO accessory-dwelling-unit provision at all, and about 75% of the Township's land base is in the ALR, where provincial rules cap any additional residence at 90 m2 on parcels of 40 ha or less.

This page is the rule for the zone. Your lot is specific — its width, what is already built on it, and how it is serviced all change the answer. The check reads Langley's own zoning and parcel data for your address, then tells you which of those things it could and could not confirm.
Two. The City of Langley and the Township of Langley are separate local governments with separate councils and separate zoning bylaws. The City is the smaller urban core; the Township surrounds it and includes Walnut Grove, Willoughby, Brookswood, Fort Langley and Aldergrove. An address in one is not governed by the other's rules.
The quickest answer is to run the free address check, which resolves the parcel against the correct municipality's data. As a rough guide, if your mail says Langley City you are in the City; most other Langley addresses are in the Township.

The rules change at every city line. These pages are built from the same bylaw reads.
Both pages describe the bylaws as they read on their stated verification dates. Bylaws change, and only the municipality can approve a build.
