RS-1 Zoning in Vancouver: What You Can Actually Build in 2026 (With the Real Numbers)

RS-1 is the zoning designation for most of Vancouver’s established single-family neighbourhoods: Dunbar, Kerrisdale, Kitsilano, Shaughnessy, East Van — if it’s a block of older detached houses, it’s almost certainly RS-1.

If you own an RS-1 property or are planning to buy one with the intention of developing, renovating, or adding a secondary suite or laneway house, this schedule governs almost everything you can and cannot do.

This guide is based directly on the RS-1 District Schedule (City of Vancouver Consultation Draft, April 2022) — the actual bylaw document, not a summary or interpretation of it.

What RS-1 is trying to achieve

Section 1.1 of the RS-1 District Schedule states the intent directly:

“The intent of this schedule is generally to maintain the residential character of the area in the form of duplexes, single detached houses, secondary suites and laneway houses.”

The key phrase: “maintain.” RS-1 is a conservation zone. Its rules are designed to prevent buildings that are out of scale with the existing neighbourhood, not to enable maximum development. Every dimensional limit in the schedule should be read through that lens.

What you can build outright (no discretion required)

Under Section 2.1, outright approval uses are permitted by right — the Director of Planning must issue a permit if your application meets the requirements:

• Single Detached House (alone or with secondary suite, as a conditional use)
• Duplex (minimum site area 334 m²)
• Accessory buildings customarily ancillary to outright uses
• Community Care Facility — Class A

“Outright” means no Director discretion. If your numbers comply with the schedule, you get the permit.

What requires conditional approval

Conditional approval uses require the Director of Planning to consider “the intent of this schedule and all applicable Council policies and guidelines.” The Director can approve with or without conditions, or refuse. This is where discretion lives.

Key conditional uses:

• Laneway House (Section 2.2.3)
• Secondary Suite (as part of a house)
• Duplex with Secondary Suite (Section 2.2.1)
• Infill Single Detached House (Section 2.2.2)
• Short Term Rental Accommodation (Airbnb-type uses)

The conditional designation means there is no guaranteed outcome even if your numbers are technically compliant. The Director can refuse based on neighbourhood character, adjacent property impacts, or applicable Council policies.

The numbers that matter most

Floor Space Ratio (FSR) — Section 3.2.1.1

Maximum FSR: 0.60

This is the most commonly violated limit — and the hardest to calculate correctly. FSR is the ratio of total floor area to site area.

For a 372 m² site (the Vancouver standard 33×120 foot lot): maximum floor area = 223 m² for all buildings combined (house + laneway house + any other structures).

Critical trap: Floor area at or above finished grade is counted. Floor area in a basement is counted if the floor surface of the storey above is 1.8 metres or more above finished grade. An above-grade basement — common on sloped Vancouver lots — counts toward your FSR even though it’s technically underground.

FSR can increase to 0.70 if:

• Floor area at or above grade doesn’t exceed 0.45 FSR
• No single floor exceeds 0.25 FSR
• The basement/cellar doesn’t project horizontally beyond the first storey perimeter

FSR can increase to 0.75 if adding a basement to a pre-July 7, 2009 house, under specific conditions.

Building Height — Section 3.2.2.3

Maximum height: 9.5 metres and 3 storeys

The “and 3 storeys” is not an alternative — it’s a combined limit. You must comply with both. A building can be under 9.5m but still violate the 3-storey limit; a building can be under 3 storeys but still violate the 9.5m limit.

Additional height envelope restrictions (Sections 3.2.2.12 and 3.2.2.13):

The third storey must be a partial storey not exceeding 50% of the storey below. This is the rule that shapes Vancouver’s characteristic attic-level third floors — the full third storey is not permitted.

The building must also fit within two height envelopes:

1. Primary envelope: A vertical line of 4.9 m at the required side yard, then extending inward/upward at 120° from vertical
2. Secondary envelope: A vertical line of 7.6 m across 60% of the site width (minimum 9.8 m), then extending inward/upward at 135° from vertical

These envelopes are easier to understand visually than in text — the RS-1 schedule includes diagrams. The practical effect is that buildings are forced to step back as they rise, preventing sheer vertical walls at their full height along the entire building width.

Side Yards — Section 3.2.2.5

For sites ≤ 18.3 m wide: Minimum = 10% of site width

For a standard 10.06 m (33 ft) Vancouver lot: minimum side yard = 1.0 m per side

For sites between 18.3 m and 30.5 m wide, the formula changes to: % of site width = (site width in metres − 1.219) ÷ 5

For sites over 30.5 m wide: 20% of site width

This regulation is the source of a common mistake: applicants calculate the side yard as a fixed 1.2 m or 1.5 m based on memory or advice. The correct number is percentage-based and varies by lot width. On a narrow 7.5 m lot, the minimum is 0.75 m — not 1.2 m. On a wider 15 m lot, the minimum is 1.5 m.

Rear Yard — Section 3.2.2.6

Minimum rear yard: 45% of site depth

On a standard 30 m deep lot: minimum rear yard = 13.5 m

This is the number that shocks most laneway house applicants. If 45% of your lot must be kept as a rear yard setback from the lane, the space available for a laneway house is constrained to the band between the lane and the 13.5 m setback line — which on a 30 m lot is a band 16.5 m deep from the lane. Then the laneway house itself has setback requirements from the lane as well.

Front Yard — Section 3.2.2.4

Minimum front yard: 20% of site depth

On a 30 m deep lot: minimum front yard = 6.0 m

This is modified by the “average front yard” rule in Section 3.2.2.16: if the average of the two adjacent sites’ front yards differs from the 20% depth by at least 1.5 m, the minimum front yard for your site is the average of the neighbours’ yards. This rule causes significant variation in allowable front yards on the same block.

Site Coverage — Section 3.2.2.7

Maximum site coverage: 40% of site area

For a 372 m² lot: maximum combined footprint = 149 m² for all buildings on the site.

This is the footprint at grade, not the total floor area. A two-storey building has only one footprint for site coverage purposes — but both floors count toward FSR.

The combination of the 40% site coverage limit and the 0.60 FSR limit means that even a fully compliant two-storey building (40% coverage × 2 storeys = 80% FSR equivalent) cannot reach the full FSR allowance without very careful design. You’d hit the site coverage limit before the FSR limit.

Maximum Building Depth — Section 3.2.2.9

Maximum building depth: 35% of site depth

On a 30 m lot: maximum depth = 10.5 m

This regulation is rarely discussed but regularly violated in renovation drawings. It limits how deep a house can be, measured from the front face of the building. A house that extends more than 10.5 m from front to back on a standard lot needs a Director of Planning relaxation.

The most common compliance failures

Based on the regulatory structure, the checks that generate the most application failures:

1. FSR overrun — existing house plus addition, or house plus laneway house, exceeds 0.60. Often discovered during application because the existing house was never measured against the current FSR formula.

2. Rear yard too shallow — applicant assumes a fixed rear yard number rather than calculating 45% of their specific lot depth.

3. Third storey too large — proposed third storey exceeds 50% of the second storey floor area.

4. Side yard wrong on atypical lots — non-standard lot widths require the formula calculation, not a fixed number.

5. Height envelope violation — building passes the 9.5 m absolute limit but violates the primary or secondary height envelope.

Checking your proposal against all five of these before submitting drawings is the single highest-value pre-application exercise available.
