Turnkey Secondary Suites That Perform
Whether it’s a basement apartment or a detached garden suite in the backyard, we manage zoning review, design, permits, and construction for Mississauga’s additional residential unit rules.
Garden Suites & ARUs in Mississauga
As expert Garden Suites Mississauga builders, we start every Mississauga project with a zoning and feasibility review specific to your property, then carry that same team through design, permits, and construction. Most homeowners can add up to two new residential units — a basement apartment paired with a detached garden suite, or in some cases a conversion to a fourplex — and we help you work out which combination your specific lot size and zoning designation actually supports. See our ARU / Garden Suites page for full process detail.
Why Mississauga Homeowners Choose Modinno
Mississauga’s additional residential unit rules depend heavily on each property’s specific zoning and lot configuration. Homeowners choose us because we confirm what is actually achievable before any design work begins, rather than designing first and discovering constraints later.

Every project starts with a review of your lot’s zoning designation and what it permits before any design investment is made.
Experience with both attached and detached options
Familiar with basement apartment, garden suite, and multi-unit conversion pathways under Mississauga’s current policies.
Fully turnkey delivery
Zoning, design, permits, and construction managed under one accountable team.
Rental-ready design standards
Layouts built with durability, storage, and tenant appeal in mind, not just minimum compliance.
How We Handle Zoning & Design for Mississauga Garden Suites
We check your property’s zoning designation and lot configuration before proposing a design — most Mississauga homeowners can add up to two additional residential units, and where your property is a townhouse in an RM5 or RM6 zone, we confirm whether a garden suite is limited to corner or through lots before you invest in drawings. Because eligibility genuinely varies by property, we treat this as a starting point we verify with the City, not a guarantee we assume applies everywhere.
Frequently Asked Questions
How many additional units can I add to my Mississauga property?
We confirm this for your specific lot — most homeowners can add up to two additional residential units, such as a basement apartment and a detached garden suite, with some properties eligible for a fourplex conversion.
Can I build a garden suite on any Mississauga lot?
We assess your specific property during feasibility review — most detached, semi-detached, and eligible townhouse lots can accommodate a garden suite, though townhouse-zone garden suites are currently limited to corner or through lots.
How long does a garden suite project take in Mississauga?
Typically 8 to 14 months from initial design through construction completion for our projects, including permit review, with permit timelines being the most variable factor.
Do you handle the zoning review before I commit to a design?
Yes — every project begins with a zoning and feasibility review specific to your property, so you know what is achievable before any design cost is incurred.
