Surrey's Zoning Bylaw 12000 lists garden suites and coach houses as accessory uses across its small-scale residential zones (the R1-R6 families). Two hard edges: on lots of 4,050 m2 (one acre) or more, seven residential zones (R1/R2/R2-O/R3/R4/R5/R5-S) lose the detached-suite entitlement (RA acreage lots keep it, and R6 has no one-acre row at all), and ALR parcels follow provincial Agricultural Land Commission rules on top of zoning.

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 52 zone codes we have mapped for Surrey, 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 |
|---|---|---|
| R1 | Likely | Suburban Residential zone — a detached suite is permitted on most lots under BC's small-scale housing rules. Garden suite 35-75 m2, up to 120 m2 where FAR headroom exists; no lane needed (the coach-house lane requirement binds R3/R4/R5/R5-S only). |
| R2 | Likely | Quarter Acre Residential zone — a detached suite is permitted on most lots under BC's small-scale housing rules. |
| R3 | Likely | Urban Residential zone — Surrey's most common detached-house zone (SSMUH successor to RF/RF-SS). Garden suite permitted on all lot configurations; a coach house needs a lane on interior lots (Part 15 F.1). Suite 35-75 m2, up to 120 m2 with FAR headroom. |
| RA | Likely | Acreage Residential zone — the ONLY Surrey zone whose >=4,050 m2 row keeps the garden-suite/coach-house entitlement (Bylaw 12000 Part 12 s.B.1 row (a) imports the accessory uses of rows (b) and (c)). Many RA parcels sit in the ALR, where provincial rules cap any additional residence — ALR status is checked separately. |
| R2O | Conditional | Oceanfront Residential zone — permitted in principle, but lot width, coverage and setbacks decide whether one fits. |
| R4 | Conditional | Small Lot Residential zone — permitted in principle, but lot width, coverage and setbacks decide whether one fits. |
| R5 | Conditional | Compact Residential zone — permitted in principle, but lot width, coverage and setbacks decide whether one fits. |
| R5S | Conditional | Special Compact Residential zone — permitted in principle, but lot width, coverage and setbacks decide whether one fits. |
| R6 | Conditional | Semi-Detached Residential zone — permitted in principle, but lot width, coverage and setbacks decide whether one fits. A COACH HOUSE here needs a rear lane or a side street. Part 1 defines a coach house as a unit above or attached to a DETACHED garage, and Part 18 s.H.3(b)(iv) requires that garage's driveway access to come “from a rear lane or side street”. In practice that means an interior R6 lot with no lane has no compliant access, while a corner lot with a flanking side street does. A GARDEN SUITE needs neither and is the fallback. R6 has no 4,050 m2 one-acre cutoff — its zone table carries no such row. |
| CD | Needs review | Comprehensive Development — each CD zone is its own bylaw attached to Schedule A and must be read individually. Note: Part 52 s.E (BL 21281) applies SSMUH minimums to pre-July-2024 CD bylaws whose principal use is a single-family dwelling or duplex, mapping the lot by size onto RA/R1-R5 regulations including garden suites. |
| A1 | Unlikely | Agricultural zone (Part 10, A-1 General Agriculture). This is not a case of the land being non-residential — the zone does permit “One single family dwelling, which may contain 1 secondary suite”. It is that a garden suite and a coach house are not among the permitted uses, so the second detached home has no route here. An ALR designation, where it applies, adds provincial limits on top. |
| A2 | Unlikely | Agricultural zone (Part 11, A-2 Intensive Agriculture). This is not a case of the land being non-residential — the zone does permit “One single family dwelling, which may contain 1 secondary suite”. It is that a garden suite and a coach house are not among the permitted uses, so the second detached home has no route here. An ALR designation, where it applies, adds provincial limits on top. |
| C15 | Unlikely | Commercial zone — not a residential lot, so a detached laneway home isn't permitted here. |
| C35 | Unlikely | Commercial zone — not a residential lot, so a detached laneway home isn't permitted here. |
| C4 | Unlikely | Commercial zone — not a residential lot, so a detached laneway home isn't permitted here. |

Garden suites and coach houses run 35-75 m2 in every SSMUH residential zone — a coach house measured excluding its garage or carport — and either may grow to 120 m2 where FAR headroom exists in RA, R1, R2, R2-O and R3 (not R4, R5, R5-S or R6, whose clauses stop at 75). Surrey's coach-house web page omits R1 from its 120 m2 list; the bylaw text includes it.
| Build | Planning estimate |
|---|---|
| One bedroom | $360,000 |
| Two bedroom | $490,000 |
| Utility connections, on top | $30,000 – $80,000 |
These are KYRAX's own mid-range planning figures, not Surrey'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.

Surrey'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 R1, R2, R3, RA. Others are conditional, need individual review, or are not favourable; the table above lists all 52 zones that were read. Which zone your lot is in is what the address check resolves.
When you enter an address, the check reads Surrey'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 Surrey's design value at the Surrey (88 Ave & 156 St.) station, 90 m up: a 1-in-50 ground snow load of 2.4 kPa, plus 0.3 kPa for rain falling on that snow. A second station, Cloverdale at 10 m, reads 2.5 kPa.
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.
