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.

Each statement below was read from the document it links to, on the date beside it. Where the wording is precise, that is because the bylaw is.
The 22 zone codes we have mapped for Langley Township, and the reading recorded for each. The list can include commercial, industrial, agricultural and site-specific codes, so its length is not necessarily a count of residential zones. This is a statement about the zone, not a verdict on any particular lot, and it is not the whole bylaw — a zone that is not listed here has not been read individually.
Likely the reading recorded for this zone is favourable. Conditional favourable in principle here; whether one fits is a lot-level question. Needs review this zone has to be read on its own, usually because it is site-specific. Unlikely the reading recorded for this zone is not favourable.
| Zone | Detached suite | Why |
|---|---|---|
| R-1A | Likely | Residential zone (s.401.2) — one SSMUH development OR one single-family dwelling plus one detached ADU, but ONLY where the dwelling has no secondary suite. ADU height 9.0 m — capped at 4.5 m for infill within 6.0 m of the rear lot line unless it is a lane-fronting coach house. ADUs not permitted in the front yard. |
| R-1B | Likely | Residential zone (s.402.2) — same rule as R-1A ('subject to the Agricultural Land Commission Act where applicable'); min lot 464.5 m2; infill height cap applies within 7.5 m of the rear lot line. |
| R-1C | Likely | Residential zone (s.402.2) — same rule as R-1B; min lot 464.5 m2. |
| R-1D | Likely | Residential zone (s.402.2) — same rule as R-1B; min lot 650 m2. |
| R-1E | Likely | Residential zone (s.402.2) — same rule as R-1B; min lot 930 m2. |
| R-2 | Likely | Residential zone (s.410.2) — SSMUH development OR one two-family dwelling OR one single-family dwelling plus one detached ADU (no secondary suite in the dwelling). |
| R-CL | Likely | Compact Lot Residential (s.403.2) — SSMUH development OR SFD + one detached ADU (no secondary suite in the SFD); infill height cap within 4.5 m of the rear lot line. |
| R-CL (A) | Likely | Compact Lot Residential A (s.404) — same structure as R-CL, subject to the applicable Community/Neighbourhood Plan density. |
| R-CL (B) | Likely | Compact Lot Residential B (s.405) — same structure as R-CL(A). |
| R-CL (CH) | Likely | Coach House compact-lot zone (s.406) — 'coach house' here means an ADU within the second storey of an accessory detached garage; garage-with-ADU height 6.75 m. |
| R-CL (SD) | Conditional | Semi-detached compact-lot zone. s.409.1(4) permits one accessory dwelling unit per lot, and only above an accessory detached garage — not a ground-oriented garden suite. s.409.6(7) requires that unit to be “simultaneously designed, building permits issued and constructed by the same builder utilizing a party wall agreement, with an accessory dwelling unit on the other fee simple lot”, so it cannot be built alone: the paired lot's suite has to happen at the same time. Four parking spaces required. |
| SR-1 | Conditional | Suburban Residential 1 (s.301.2) — SFD + one detached ADU where the dwelling has no secondary suite, subject to the ALCA where applicable. Min lot 3,716 m2, so many SR-1 lots exceed the 4,050 m2 SSMUH ceiling and take the one-ADU path only. |
| SR-2 | Conditional | Suburban Residential 2 (s.302.2) — this zone works the opposite way from most: a detached accessory dwelling is permitted only where the lot is outside the urban containment boundary and the house has no secondary suite. Minimum lot 8,094 m². |
| SR-3 | Conditional | SUBURBAN Residential 3 (s.303.2) — SFD + one detached ADU (no secondary suite), subject to the ALCA where applicable; min lot 1,765 m2. |
| CRE-1 | Needs review | Comprehensive Rural Estate zone (s.413) — read the zone text against the specific site. |
| FH-1 | Unlikely | Residential Float Home (s.412) — not a detached-suite lot. |
| MH-1 | Unlikely | Residential Mobile Home Park (s.411) — not a detached-suite lot. |
| R-CL (MH) | Unlikely | Manorhome compact-lot zone. Section 408.1 reads “In the R-CL(MH) Zone only the following uses are permitted and all other uses are prohibited” and lists just three: an accessory detached garage, accessory home occupations, and manorhomes. An accessory dwelling unit is not among them, so a detached suite is not available here. |
| R-CL (RH) | Unlikely | Rowhouse compact-lot zone. Section 407.1 reads “In the R-CL(RH) Zone only the following uses are permitted and all other uses are prohibited” and lists just three: an accessory detached garage, accessory home occupations, and rowhouses. An accessory dwelling unit is not among them, and unlike R-CL, R-CL(A) and R-CL(B) this zone has no “residential uses subject to” clause that would add one. A detached suite is not available here. |
| RU-1 | Unlikely | Rural zone (s.201.2) — NO accessory-dwelling-unit provision exists; Bylaw 6020 never amended the RU zones. 'Subject to the Agricultural Land Commission Act, no more than two single family dwellings or mobile homes' per lot. On ALR parcels a second dwelling is an ALR 'additional residence': max 90 m2 (<=40 ha) or 186 m2 (>40 ha), only where one residence exists at construction start and the principal is <=500 m2. |
| RU-2 | Unlikely | Rural zone (s.202.1) — all RU-1 uses; same no-ADU rule and ALR gate. |
| RU-3 | Unlikely | Rural zone (s.203.1) — all RU-1 uses; same no-ADU rule and ALR gate. |
Detached ADU height 9.0 m — but capped at 4.5 m for infill housing within 6.0 m (R-1A) / 7.5 m (R-1B-E) / 4.5 m (R-CL) of the rear lot line unless it is a lane-fronting coach house, which is exactly where a laneway unit goes. There is NO floor-area cap on a Township detached ADU — height, setbacks and lot coverage are what size one. The often-quoted 'seven gates' (s.102 as amended by Bylaw 6020: urban containment boundary; lot under 4,050 m2; municipal sewer AND water; no pre-Dec-7-2023 s.611 heritage designation; not in the Willowbrook TOA (Bylaw 6021); max 3 units at or below 280 m2; no arterial vehicular access) sit INSIDE the definition of 'small-scale multi-unit housing development' and bind ONLY that houseplex path — NOT the one-SFD-plus-one-detached-ADU path a laneway home uses. Arterial-road frontage does not prohibit the ADU either: on the ADU path it only changes a setback. The ADU path's own condition, in every zone, is that the single-family dwelling has NO secondary suite.
| Build | Planning estimate |
|---|---|
| One bedroom | $355,000 |
| Two bedroom | $485,000 |
| Utility connections, on top | $30,000 – $80,000 |
These are KYRAX's own mid-range planning figures, not Langley Township's and not a quote. They are for working out whether the idea is worth pursuing. Real quotes for a completed build in this region have ranged from roughly $275,000 to $840,000 depending on size, site access, servicing and finish, and only a site visit narrows that.
| Suite | Indicative band |

| One bedroom | $1,765 / month |

Langley Township's own documents use both terms, and this page treats them as one question: a self-contained home behind the main house. Where a particular zone treats them differently — a lane requirement that applies to one and not the other, for instance — that zone's row in the table above says so in the bylaw's own words.
The reading recorded as favourable covers R-1A, R-1B, R-1C, R-1D, R-1E, R-2, R-CL, R-CL (A), R-CL (B), R-CL (CH). Others are conditional, need individual review, or are not favourable; the table above lists all 22 zones that were read. Which zone your lot is in is what the address check resolves.
When you enter an address, the check reads Langley Township's own parcel and zoning data for that specific lot. It resolves the parcel, reads the zone, and tests whether a suite of the size the bylaw permits fits behind the existing house once coverage and setbacks are taken out.
It reports what it could not establish as plainly as what it could. A favourable answer requires a real zoning read — the absence of an objection is not treated as a permission. Pre-screening only, not a permit determination.
BC Building Code 2024 · checked 2026-09-10
Outside the City of Vancouver, a laneway home in the Lower Mainland is designed to the BC Building Code 2024, which took effect on 8 March 2024 and is based on the National Building Code of Canada 2020. It applies to projects whose building permit was applied for after that date, so the edition that governs your build is fixed by when you apply, not by when you break ground.
The 2024 edition's earthquake design and adaptable dwelling requirements did not arrive with the rest of it. The 2018 rules stayed in force for permits applied for up to 9 March 2025, and from 10 March 2025 the 2024 requirements apply to all new projects. A set of drawings prepared under the older seismic rules is therefore only still usable if the permit application beat that date.
Projects already in stream when the edition changed can qualify for an extended exemption running to 8 March 2027. If a design has been sitting for a couple of years, which edition it was drawn to is worth confirming before it goes any further.
The provincial code takes Langley Township's design value at the Langley station, 15 m up: a 1-in-50 ground snow load of 2.4 kPa, plus 0.2 kPa for rain falling on that snow.
Across the stations the provincial table lists for these municipalities, the ground snow load runs from 1.3 kPa at Ladner to 2.9 kPa at Burnaby (Simon Fraser Univ.) — more than double. Coquitlam, which the table does not list, publishes its own values, and they reach 5.7 kPa between 401 and 425 m. That is why the same laneway design can need a heavier roof structure in one city than the next. Wind barely varies: at the stations the table lists, 1-in-50 hourly wind pressures run 0.44–0.47 kPa.
These are ground loads at a named weather station and elevation, not the load on a roof: the code derives roof loads from them, and a station is not a lot. The designer of record works out the value for the actual site.
