Step 1: As-Built Code Audit
Phase 01We conduct a precise on-site 3D LiDAR survey of your home to record existing wall locations, ceiling joist depths, bedroom window dimensions, and plumbing stacks.
Step 2: Fire & Sound Separation Design
Phase 02We draft compliant building sections specifying the exact drywall, insulation, and resilient channel assemblies required to satisfy your municipal building inspector.
Step 3: Mechanical & Egress Plans
Phase 03We map out compliant emergency exit routes, window enlargements (if needed), interconnected smoke/CO alarms, and coordinate independent heating controls.
Step 4: City Submission & Occupancy
Phase 04We submit the complete building permit package to your municipality, handle plan checker comment letters, and support you through final occupancy sign-off.
