10. A zoning by-law controls the use of land in our
community. It includes:
how land may be used
where buildings and other structures can be located
the types of buildings that are permitted and how they
may be used
the lot sizes and dimensions, parking requirements,
building heights and setbacks from the street.
Zoning by-laws put the plan into effect and provide for its
day-to-day administration. They contain specific
requirements that are legally enforceable. Construction or
new development that doesn't comply with a zoning by-
law is not allowed, and the municipality will refuse to
issue a building permit.
Many municipalities have a comprehensive zoning
by-law that divides the municipality into different land
use zones, with detailed maps. The by-law specifies the
permitted uses (e.g. commercial or residential) and the
required standards (e.g. building size and location) in
each zone.
Some rural municipalities may have a free-standing
zoning by-law that covers only specific property that an
owner proposes to develop.
