Construction of a Duplex, Part 1
Zoning and Planning Rules
When it comes to planning and approvals, zoning is your first step. In Dartmouth, duplex construction is permitted only on R2-zoned lots. Most residential properties are initially zoned as R1. To proceed with building a duplex, you'll need to complete and submit HRM Rezoning Form ZM-01 to request an R2 designation. After that, ensure your lot meets the required size and frontage specifications for R2 zoning.
Getting Permits
Before starting construction, you need to secure the necessary development and building permits from Halifax Regional Municipality (HRM).
Permit Applications
You can submit a development permit application through HRM's online portal or in person. Once approved, you’ll need to apply for a building permit with detailed project drawings. The fees for permits are based on your project's value - check the HRM website for specific details.
Required Documents
When applying, make sure you have the following:
- A site plan showing property boundaries, building footprints, setbacks, driveways, and parking layouts
- Construction drawings (including floor plans, elevations, foundation details, and sections)
- Proof of property ownership
- Contractor details, such as a valid business licence
- Any additional reports or plans requested by HRM, like grading, drainage, or energy-efficiency assessments
HRM Approval Process
The approval process typically includes:
- A review to ensure your application is complete
- A technical review covering building standards, engineering, and fire prevention
- Permit issuance, if everything meets HRM’s requirements
To avoid unnecessary delays, consider scheduling a pre-application meeting with HRM staff.
