RM8 zone, Mississauga: Back To Back And/Or Stacked Townhouses (exception zones only)
Section 4.13A.1 (regulations per Exception Table 4.13A.2.14, RM8-14); exceptions in Section 4.13A.2 of the City of Mississauga Zoning By-law 0225-2007, as amended by 0181-2018/LPAT Order 2019 February 15, 0325-2008, 0190-2014, 0174-2017, 0183-2021.
RM8 is Mississauga's zone for back-to-back and stacked townhouse developments; it has no base table of its own, so every RM8 property uses the RM8-14 exception regulations unless a numbered exception (RM8-1 to RM8-15) changes them.
