Maximum Number of Storeys

Definition of Storey (Regulation 800.50(820)): A storey is a level of a building, other than a basement, located between any floor and the floor, ceiling, or roof immediately above it.

Note: All floors located above established grade are not limited by a restriction on the total number of storeys. Basements, as defined by Regulation 800.50(80), do not count as a storey under this restriction.

Maximum Number of Storeys (Regulation 10.20.40.10(3)):

• (3) Minimum Number of Storeys:
  • (A) The maximum number of storeys allowed in a building on a lot in the RD zone is determined by the numerical value following the letters “ST” on the Height Overlay Map.
  • (B) If there is no numerical value following the letters “ST” on the Height Overlay Map, the number of storeys is not limited by this regulation.
  • (C) The permitted maximum number of storeys in regulation (A) does not apply to a duplex, triplex, or fourplex.

Tip:

• If a restriction on the number of storeys applies from a Chapter 900 exception, it continues to apply. The exception to restrictions on the number of storeys only applies to standards from the Height Overlay Map.
