What BC law allows here
Under BC's small-scale multi-unit housing law, the city must allow at least 4 homes on this lot (a multiplex, a house with suites, or a house plus a laneway home).
If this lot were rezoned
| Floor space | Homes | Land $/buildable ft² | |
|---|---|---|---|
| Today's zoning (RA) from the city's bylaw, FAR 0.66 | 28,548 ft² | about 22 | $73 |
| Small-scale housing (Bill 44) up to 4 homes, BC law, FAR 0.70 | 30,493 ft² | up to 4 | $68 |
Rough planning numbers: homes assume about 85% sellable floor space and 750 ft² apartments (1,100 ft² for houses and townhouses). Transit-area figures are the minimum a city must allow on a rezoning, not an approval. Land cost uses the assessed land value. Confirm with the city.
