What the zoning allows on this lot

- Lot coverage: 40% of the lot, or 1,573 sq ft (146 m²), for 3 or 4 units. That is the share of the lot buildings may sit on, seen from above.
- Permeable area: 35% of the lot, or 1,376 sq ft (128 m²), for 3 or 4 units. That share must let rain soak into the ground.
- Landscaped area: 20% of the lot, or 786 sq ft (73 m²), for 3 or 4 units. That share must be planted, with soil, trees and shrubs.
- Distance from property lines: at least 9 ft 10 in (3 m) from the front, 4 ft 11 in (1.5 m) from the back and 3 ft 11 in (1.2 m) from each side. On a corner lot, 9 ft 10 in (3 m) from the side street, or 0.2 times the lot width if that is less.
- Height: up to 3 storeys. Any part of a building within 16 ft 5 in (5 m) of the rear lot line can be at most 23 ft (7 m) tall. From the lowest floor to the highest ceiling above it can be at most 32 ft 10 in (10 m).

- A lot with 3 or more units needs an enclosed space for garbage, organics and recycling.

- Yes. A separate unit at the back of the lot is one of the units this zone already allows, so it counts towards the lot's number of units rather than being an extra.
- It has to stand at least 23 ft (7 m) from the building at the front, because two buildings with units on one lot must be that far apart.
- Within 16 ft 5 in (5 m) of the rear lot line it can be at most 23 ft (7 m) tall, lower than the 3 storeys allowed further into the lot.
- It shares the lot's floor space, lot coverage and parking figures with the building at the front, rather than adding to them.

Confirm the rules with the city's planning staff before you pay for a design.
