Real Estate Investors in Mississauga: local conditions
Mississauga's ARU by-law caps accessory structures at 10% rear-yard coverage, which on a typical Erin Mills lot works out to roughly 645 sq ft - enough for a two-bedroom garden suite but not for the three-bedroom units clients often ask about first. We size the concept to that percentage before drawing anything. Mississauga permits additional residential units under its 2022 ARU by-law - up to two units in the main dwelling plus one in an accessory structure, subject to a maximum 10% rear-yard coverage.
Large 1970s-90s subdivision lots with attached garages; garage conversions and rear coach houses are both common outcomes. Lake-moderated winters in Mississauga - 112 cm of snow, -3.4°C average - give one of the longest build seasons in the region (April-November), which shortens the permit-to-occupancy timeline on real estate investors.
Real Estate Investors on a Mississauga lot: what's involved
An investment ADU is underwritten before it is designed: the build cost, the $6,500-$11,000 in approvals and the achievable Mississauga rent decide the unit size, not the other way round. We price the feasibility stage as a standalone deliverable so the numbers can be tested against your Mississauga parcel before any commitment to design. A legal second unit changes the appraisal basis of the property, which is the return most owners underestimate next to the monthly rent.

Related service: Secondary Suites
Large 1970s-90s subdivision lots with attached garages; garage conversions and rear coach houses are both common outcomes. Mississauga scores 58/100 on walkability, so many tenants here do not need the extra parking space - that frees rear-yard area for the unit itself. We work regularly in Port Credit, Streetsville, Cooksville.

A legal, permitted second unit changes how the property is appraised in Mississauga - it is valued partly on income rather than purely on comparables. An unpermitted suite does the opposite: it is discounted or excluded entirely, and it surfaces on every purchaser's title and insurance review.
