Building Permit Checklist: Everything You Need

Why a Complete Application Matters

The single biggest cause of building permit delays in Nova Scotia is an incomplete application. When your submission is missing documents, drawings, or information, the municipality returns it for revisions. Each revision cycle adds weeks or even months to your timeline. In busy municipalities like Halifax Regional Municipality, a revision cycle can add 4 to 8 weeks because your application goes back to the end of the review queue.

A complete, well-organized application signals professionalism to the plan reviewer and dramatically increases your chances of first-time approval. The investment in preparing a thorough application pays for itself many times over in avoided delays and frustration.

This checklist covers the documents and drawings required for most building permit applications in Nova Scotia. The specific requirements for your project may vary depending on the municipality, project type, and scope of work. Use this as a comprehensive starting point, and confirm the exact requirements with your local building department.

Required Documents Checklist

1. Property Information

Before any design work begins, you need to gather key information about your property.

• Property Identification Number (PID): This is the unique identifier for your property in Nova Scotia's land registry. You can find it on your property tax bill, deed, or by searching the Nova Scotia Property Online database.
• Deed or proof of ownership: Some municipalities require evidence that you are the property owner or have the owner's authorization to apply for a permit.
• Property survey or certificate of location: A survey by a licensed Nova Scotia Land Surveyor showing property boundaries, existing structures, easements, and rights-of-way. For new construction, a recent survey is almost always required. For renovations, an existing survey may suffice if it is reasonably current and accurate.
• Zoning information: Confirm your property's zone designation and review the applicable land-use bylaw to ensure your project is permitted. Some municipalities include zoning confirmation as part of their development permit process.
• Septic system information (rural properties): If your property is on a septic system, you may need documentation of the existing system's capacity, particularly if you are adding a dwelling unit or increasing the number of bedrooms.

2. Architectural Drawings

Architectural drawings are the core of your permit application. They describe the design of your project in detail and demonstrate compliance with the building code.

• Floor plans: Detailed plans for every level of the building, showing room layouts, dimensions, door and window locations, wall types, fixture locations, and room names and areas. Plans must be drawn to a standard scale (typically 1/4" = 1'-0" for residential projects).
• Building elevations: Exterior views of all four sides of the building (or affected sides for renovations), showing exterior finishes, window and door types, roof slopes, grade lines, and overall building heights.
• Building sections: Cross-sections through the building showing the internal structure, floor-to-floor heights, ceiling heights, foundation details, roof construction, and insulation assemblies. At least one longitudinal and one transverse section is typically required.
• Construction details: Enlarged details of critical construction assemblies, such as wall sections (showing all layers from exterior to interior), foundation details, roof edge details, window and door head/jamb/sill details, and fire separation details.
• Door and window schedules: Tables listing every door and window in the project with type, size, material, fire rating (where applicable), and energy performance values.
• Room finish schedule: A table listing the floor, wall, and ceiling finishes for each room.
• General notes and code compliance: Notes on the drawings referencing applicable code requirements, fire ratings, accessibility standards, and other regulatory compliance information.

3. Structural Engineering

Structural engineering drawings must be prepared and stamped by a Professional Engineer (P.Eng) licensed in Nova Scotia.

• Foundation plan: Showing the foundation layout, footing sizes, wall thicknesses, reinforcement details, and connection details.
• Floor framing plans: For each floor level, showing joist sizes, spacing, direction, headers over openings, bearing points, and connection details.
• Roof framing plan: Showing rafters or trusses, sizes, spacing, ridge details, and load paths.
• Structural details: Beam calculations, point load details, shear wall design, hold-down connections, and any special structural conditions.
• P.Eng stamp and signature: All structural drawings must bear the professional stamp and signature of the engineer of record.

4. Mechanical and Electrical Plans

The level of mechanical and electrical documentation required depends on your project type.

• Heating system layout: Showing the type and location of the heating system, distribution (ductwork, piping, or baseboards), and thermostat locations.
• Ventilation plan: Showing the HRV or exhaust fan locations, ductwork, and outdoor air intakes and exhausts. Ventilation design must comply with the building code and energy code.
• Plumbing layout: Showing fixture locations, drain/waste/vent routing, water supply routing, and hot water system. Required for plumbing permit applications.
• Electrical layout: Showing panel location, circuit layout, outlet and switch locations, lighting, and smoke/CO alarm locations. Required for electrical permit applications.

5. Site Plan

A site plan is required for virtually every building permit application. It shows the project in the context of the property.

• Property boundaries: Showing all property lines with dimensions and bearings.
• Existing and proposed structures: Showing all buildings on the property, including the proposed construction, with dimensions from property lines (setbacks).
• Setback dimensions: Clearly showing the distance from the proposed construction to all property lines, demonstrating compliance with zoning setback requirements.
• Easements and rights-of-way: Showing any registered easements or rights-of-way on the property.
• Driveway and parking: Showing vehicular access, driveway location, and parking spaces.
• Grading and drainage: For new construction, showing proposed grading, drainage patterns, and stormwater management.
• Servicing: Showing water, sewer (or septic), and electrical service connections.

6. Energy Code Compliance

All new construction and most significant renovations must demonstrate compliance with the National Energy Code of Canada for Buildings (NECB) or Part 9.36 of the National Building Code.

• Prescriptive compliance: Documentation showing that all building envelope assemblies (walls, roof, windows, foundation) meet or exceed the prescriptive insulation and performance requirements for your climate zone.
• Performance compliance (alternative): An energy model prepared by a qualified energy advisor demonstrating that the building's overall energy performance meets or exceeds the code requirement. This approach offers more design flexibility.
• Mechanical system efficiency: Documentation of heating, cooling, and ventilation system efficiencies.

7. Application Forms and Fees

The administrative components of your application include:

• Completed application form: Your municipality's building permit application form, fully completed with project details, owner information, contractor information, and estimated construction value.
• Development permit application: If required, a separate development permit application demonstrating zoning compliance.
• Application fees: Payment of the required municipal permit fees (see our permit cost guide for typical fee ranges).
• Owner authorization: If the applicant is not the property owner, a letter of authorization from the owner.
• Contractor information: Some municipalities require the name and license number of the general contractor.

Common Mistakes That Delay Permits

Based on our experience managing hundreds of permit applications across Nova Scotia, here are the most common mistakes that cause delays.

1. Missing or Incomplete Drawings

The most common reason for application returns is simply missing information. A floor plan without dimensions, missing building sections, or absent construction details will trigger a revision request. Make sure every required drawing is included and complete before submitting.

2. Inadequate Fire Separation Details

For projects involving secondary suites or multi-unit construction, fire separation is a critical code requirement. Applications that lack detailed fire separation drawings, fire-stopping details, or fire-rated assembly specifications are frequently returned. Plan reviewers scrutinize fire safety closely.

3. Non-Compliant Egress

Bedroom egress windows that do not meet minimum size requirements, missing window wells, or emergency escape routes that do not comply with code are common issues, particularly in basement suite applications.

4. Missing Structural Engineering

Submitting architectural drawings without the required structural engineering is a guaranteed return. Any project that involves structural work needs P.Eng stamped structural drawings. Do not assume the municipality will accept architectural drawings alone.

5. Zoning Non-Compliance

Starting the building permit process without confirming zoning compliance can waste time and money. If your project does not comply with your property's zoning (setbacks, lot coverage, use), you may need a variance, development agreement, or project redesign before you can even apply for a building permit.

6. Poor Drawing Quality

Sketchy, hand-drawn plans, plans that are not to scale, or plans with illegible text frustrate reviewers and invite scrutiny. Professional-quality, CAD-produced drawings at standard scales communicate competence and make the reviewer's job easier.

7. Missing Energy Code Documentation

Energy code compliance is increasingly enforced across Nova Scotia. Applications that lack energy compliance documentation or show assemblies that do not meet minimum insulation values will be returned.

How to Organize Your Submission

A well-organized submission makes a positive impression and speeds up the review process. Here are our recommendations.

1. Use a drawing index. Include a cover sheet or index listing every drawing in the package with its drawing number and title.
2. Number your drawings logically. Use a consistent numbering system (e.g., A1, A2 for architectural; S1, S2 for structural; M1 for mechanical; E1 for electrical).
3. Include a project summary. A brief cover letter or project description summarizing the scope of work helps the reviewer understand the project quickly.
4. Print at the correct scale. Ensure drawings are printed at the scale noted on the drawing. Scaled-down prints make plan review difficult and can lead to misunderstandings.
5. Provide the required number of copies. Check with your municipality for the number of hard copies required. Many municipalities now accept digital submissions, but some still require paper copies.
6. Include all supporting documents. Attach the application form, fees, owner authorization, survey, and any other supporting documents in a clear, organized package.
7. Keep a copy for yourself. Always retain a complete copy of your submission for your records.

When we manage permit applications at Nova Scotia Permit, we handle all of this organization and submission on your behalf. Our applications are assembled to the standards that municipal reviewers expect, which contributes to our high first-time approval rate.

Frequently Asked Questions

How many copies of drawings do I need to submit?

This varies by municipality. Some municipalities now accept digital-only submissions (PDF files). Others require 2 to 3 sets of printed drawings. Some require both digital and printed copies. Always check your municipality's specific submission requirements before printing. HRM, for example, has transitioned largely to digital submissions through their online portal.

Do I need a property survey for every permit application?

Not always. A property survey is typically required for new construction, garden suites, and any project where the building's position relative to property lines needs to be verified. For interior renovations and basement suite conversions in an existing building, a survey is usually not required. However, a site plan showing the property and existing structures is still needed. If you have an existing survey, it can often be used if it is reasonably current.

Can I submit my application online?

Some Nova Scotia municipalities accept online submissions, while others still require in-person or mail submissions. HRM offers an online application portal for many permit types. Smaller municipalities may have more traditional submission processes. Check with your specific municipality for their current submission methods and any digital format requirements (file types, maximum sizes, naming conventions).

What if my application is returned for revisions?

If your application is returned with reviewer comments, address every comment thoroughly and resubmit with a written response to each item. Do not ignore or partially address comments, as this will trigger another revision cycle. When resubmitting, clearly mark revised drawings (use revision clouds or delta symbols) and include a cover letter summarizing all changes made. If you are working with a professional team, they should manage this process for you.
