Legal Basement Apartments

Your Basement Pays Rent.

Legal second units in Orangeville, Caledon and Dufferin County, built to code with permits handled.

Why now

More homeowners are adding a second unit.

Ontario now allows up to three residential units on most residential lots, which makes a basement apartment one of the most practical ways to add income or keep family close. A legal unit can help carry the mortgage, house an aging parent, or give grown kids a place to start.

The key word is legal. An unpermitted apartment can cause trouble with insurance, resale and safety. We build second units the right way: designed to the Ontario Building Code, with the permit pulled and every inspection passed.

  • Zoning and feasibility check before you spend money on drawings
  • Drawings and building permit application handled for you
  • Fire separation between units, plus interconnected smoke and carbon monoxide alarms
  • Proper exits and egress windows for bedrooms
  • Sound insulation so both households can live comfortably
  • Separate entrance where the layout allows
  • Full kitchen and bathroom, including breaking concrete for drains
  • Electrical, heating and ventilation sized for a second household

How it works

From bare basement to legal unit.

1. Free on-site visit

We look at your basement, ceiling height, windows, entrance and services, and tell you honestly whether a legal unit makes sense.

2. Options + plan

Every quote comes with options, so you choose the layout and finish level that fits your budget and rental goals.

3. Permits + build

We handle drawings, the permit and the build, with one team coordinating every trade.

4. Inspections + handover

We book and pass the inspections, then hand over a finished unit that's ready for a tenant or family member.

Paying for it

Ask about these before you start.

Federal programs now support secondary suites. Ask your lender about refinancing to fund a suite, and ask your accountant whether the Multigenerational Home Renovation Tax Credit applies if the unit is for a senior or family member with a disability. Programs change, so always confirm the current rules.
