New Custom Homes in Mississauga

A building permit with architectural, structural, mechanical and energy-compliance drawings and a grading and servicing plan, plus any minor variance or conservation permit the lot triggers. The City of Mississauga Planning and Building Department issues the building permit and, at the end, the occupancy permit, and inspects the build in between. Mississauga’s Lot Grading and Municipal Services Protection By-law governs grade changes, and residential grading plans are reviewed before the building permit is issued. We finish the grading plan first for that reason.

If the lot is inside the regulated area of Credit Valley Conservation (CVC), yes. Eastern Mississauga along Etobicoke Creek is under the Toronto and Region Conservation Authority. We check which authority maps the lot before anything else. Under Ontario’s Conservation Authorities Act, building a house or grading a site in hazardous lands, wetlands, river or stream valleys or shorelines at risk of flooding or erosion needs the authority’s permit, because O. Reg. 41/24 counts both as development. You can ask the authority for a pre-submission consultation, and on a lot near a watercourse we do, before the footprint is fixed. Whichever authority’s permit the lot needs comes first, then the Mississauga building permit.

It depends on the district. The first check is whether your lot is inside one. Mississauga has three Heritage Conservation Districts designated under Part V of the Ontario Heritage Act: Meadowvale Village, Old Port Credit Village and Streetsville. For a lot inside a district, we confirm with the City of Mississauga Planning and Building Department what it asks of a new house before the massing is drawn.

Yes. We take on new custom homes across Mississauga, including Port Credit and Streetsville, within an hour of our Richmond Hill office. The first consultation is free, by phone or on site.

Three things to start: lot address and a survey, if you have one; your sketch, brief or a plan from another designer; and whether the lot is serviced or needs a well and septic. Send those and we tell you what the City of Mississauga Planning and Building Department will ask for before we quote.

The standards for your zone in Mississauga Zoning By-law 0225-2007 set it: height, setbacks and how much of the lot the house may cover. On a teardown lot, the house coming down sets no limit of its own. Because the by-law has been amended many times since 2007, we check the current consolidation for your address, and anything the design needs beyond it goes to the Committee of Adjustment first.

They can. Demolition, the new foundation and the service trenches all dig near roots, and Mississauga’s Private Tree Protection By-law 0021-2022 requires a permit to injure or remove a private tree of 15 cm or more, even one that is dead. We locate each of those trees on the survey before the house is placed, since the tree permit is a separate application from the building permit the Planning and Building Department issues.

Yes. Ontario’s Building Code Act requires a permit before a building is demolished, not only before one is built. In Mississauga the Planning and Building Department issues it, and on a teardown lot we prepare the demolition application through ePlans together with the drawings for the new house.

Yes. Mississauga allows a detached or semi-detached house up to two additional units, and designing them in from the start avoids reworking walls, exits and heating later. They are drawn on the house’s own permit set, so the Planning and Building Department reviews the house and its units together.

Sometimes, if our P.Eng finds it sound and able to carry the new house, but weigh it before deciding. Ontario notes that new homes built on existing footings or foundations may not be covered by the Tarion warranty, and on a teardown lot the new design may want a footprint the old walls do not match. Either way, the structural drawings for the Planning and Building Department show what is kept and what is new.
