A legal basement apartment is a self-contained secondary dwelling unit within your home’s existing foundation — fully permitted, independently accessed, and compliant with all Ontario Building Code requirements. Unlike illegal basement suites, a legal conversion protects your insurance coverage, mortgage standing, and exposes you to zero municipal fine risk.

Based in Toronto, Ontario, we proudly provide professional legal basement apartment services across the Greater Toronto Area. Whether you’re creating a secondary suite for rental income, accommodating extended family, or maximizing the value of your home, Jacko Contracting delivers expert craftsmanship and seamless project management from design and permits to final construction and finishing.
Thank you for choosing Jacko Contracting as your trusted partner for legal basement apartments. Let’s transform your basement into a safe, stylish, and code-compliant living space that enhances your property and supports your long-term goals.
We offer everything to build or improve your project in Toronto and the GTA.

We had a sunroom put on the back of our house last year and then contracted Jacko to add a deck. What he did was extremely detailed and thorough and we're very satisfied with the result. During construction, we changed our minds a number of times on what we wanted and Jacko worked with us to sort out our ideas. After the deck was complete, Jacko helped us remodel our backyard with new fencing, a paver walkway, a raised flower bed, and a pond. We also asked him to do a number of small jobs, such as installing a solar light, and he did them without complaint. We're very, very pleased with Jacko's work.

Most legal basement apartment conversions take 10–16 weeks from permit approval to occupancy. The permit approval process itself (handled by us) typically takes 4–8 weeks with the City of Toronto. We provide a firm project schedule during your free feasibility consultation.
A full turnkey legal basement conversion in the GTA typically ranges from $85,000 to $145,000 depending on size, existing conditions, and finish level. This includes all permits, engineering, structural work, mechanical systems, and finishes. We provide a full itemized quote after your property audit — no hidden costs.
No — if your existing ceiling height is below the OBC minimum of 1,950mm (6'5"), we offer basement underpinning and foundation lowering as an integrated service. We assess underpinning feasibility as part of your free site audit. Many Toronto homes built before 1970 require this and it's a routine part of our work.
Yes — we offer full retroactive legalization and retrofit services. We audit your existing suite, identify every OBC code gap, and bring the unit into full compliance. This is often more cost-effective than a ground-up conversion. We handle all permit submissions, required upgrades, and final inspections.
