The rules
| Name | Single Detached Residential - Small Lot |
|---|---|
| Homes allowed | SSMUH: 3 on lots <=280 m2, 4 on lots 280-4,050 m2, 6 within 400 m of a prescribed bus stop (s.5.5.2-5.5.4), only inside SSMUH Areas (Schedule A Map 3); not in Transit-Oriented Areas. Base: house + secondary suite + ADU |
| Floor space ratio | 0.7 on lots 0–280 m²; 0.8 on lots 280–4,050 m²; 0.5 on lots over 4,050 m² |
| Floor space notes | SSMUH table (s.8.5.4, added by Bylaw 3460): FAR 0.7 for 3 units, +0.1 per extra unit: 0.8 for 4, 0.9 for 5, 1.0 for 6 units. Tiers shown are the max-unit form: lots <=280 m2 get 3 units (0.7); 280-4,050 m2 get 4 units (0.8), or 6 units (FAR 1.0) within 400 m of a prescribed bus stop (s.5.5.4); lots >4,050 m2 are not SSMUH-eligible and fall back to the base single-detached FAR (0.5, s.8.5.3). Base single-detached FAR is 0.7 on lots <555 m2 and 0.5 on lots >=555 m2 (s.8.5.3). Floor area for single detached, semi-detached, ADU and SSMUH is counted under s.5.3.4(a): includes all floor areas and enclosed parking over 23 m2 per required space; excludes basements 60%+ below grade, crawl spaces, exterior wall thickness up to 0.165 m (0.305 m for insulation), open-to-below areas (unless double height over 4.57 m), elevator shafts, roof access up to 3.5 m2, green-building mechanical space up to 9.29 m2 per building, and ADU exterior-access waste storage up to 4.6 m2. Bylaw 3511 (2025) added these forms to the carve-out in s.5.3.4(b), which now applies only to other uses. |
| Height | 10.5 m (34 ft) |
| Height notes | SSMUH (s.8.5.4): 10.5 m for up to 4 units, 11.5 m for 5-6 units, accessory 4.0 m; storeys not stated in SSMUH table. Base single detached (s.8.5.3): same as RS1; ADU 6.71 m. Height is measured per definition + s.5.3.3 exceptions. |
| Lot coverage | 45% on lots 0–4,050 m²; 45% on lots over 4,050 m² |
| Coverage notes | SSMUH: 45% for up to 4 units, 50% for 5-6 units (s.8.5.4). Base single detached: 45% of lot for all buildings, accessory/ADU max 65 m2 (s.8.5.3). |
| Setbacks | front 4.6 m (15 ft), side 1.5 m (5 ft), rear 4 m (13 ft), flank 3 m (10 ft) |
| Setback notes | SSMUH values (s.8.5.4): front 4.6 m; interior side 1.5 m; exterior side (flank) 3.0 m; rear 1.5 m with lane or 4.0 m without lane; separation between buildings 6.1 m front-to-back, 2.4 m side-to-side, 2.0 m accessory. Base single detached (s.8.5.3): front 6.0 m, interior side 1.2 m (accessory 0.9 m), exterior side min 1.8 m on corner lots, rear 7.5 m; accessory/ADU rear 1.5 m. Base FAR is 0.7 on lots <555 m2 and 0.5 on lots >=555 m2. Interim RS1-S Rezoning Policy limits new RS1-S lots to 3 units (city policy). |
| Bonus density | No zone-level bonus. Citywide density bonus (s.7) is being replaced by pending Bylaw 3549 (2026), which targets TOA/higher-density sites, not SSMUH lots. |
