Legal Basement Apartment Process

Built Safely. Built Legally. Built by Bauser’s Renovations.

At Bauser’s Renovations, we follow a clear, proven process to design and build fully legal basement apartments across Durham Region and the GTA. We handle every step—from permits to inspections—so you get a safe, compliant, and income-producing secondary suite.

1. Before You Start

Check Your Municipal Requirements

We contact your local municipality to confirm zoning, by-laws, and eligibility for a secondary suite. Every city has different rules, and we make sure your project meets them from day one.

Hire Qualified Professionals

Our team works with licensed architects, designers, and engineers to create detailed, code-compliant plans. We ensure the layout, structure, and safety features meet the latest Ontario Building Code.

Assess Your Home’s Current Condition

If your home is older, we inspect the existing structure to identify any upgrades required for compliance—such as ceiling height, foundation condition, or fire separation needs.

2. Construction & Code Compliance

Permits and Approvals

We submit all professional drawings to your municipality and secure the required building permits before construction begins.

Structural & Safety Features

We build all mandatory safety elements, including:

  • A dedicated, separate entrance

  • Fire-rated walls and ceilings

  • Proper smoke and CO alarm systems

  • Fire separation between units

Egress Windows & Ventilation

We install egress-compliant windows in bedrooms and living spaces to meet escape, safety, and ventilation standards.

Electrical (ESA-Compliant)

Our licensed electricians install safe, code-compliant electrical systems with proper lighting, outlets, grounded wiring, and ESA inspections.

Plumbing & HVAC

We build a fully functional kitchen and bathroom and ensure the basement suite has proper heating, cooling, and ventilation for year-round comfort.

3. Final Steps

Inspections Throughout Construction

We coordinate and pass all building, plumbing, HVAC, fire, and electrical inspections during and after construction to ensure full compliance.

Final Approval & Registration

Once the suite passes every inspection, we help you register your basement apartment with your municipality. This final step makes your suite officially legal and ready for tenants.
