A building permit is the City of Nanaimo’s approval to begin specific construction work.
Depending on the project, the review may involve:

• Building code requirements
• Zoning and permitted use
• Occupancy
• Fire and life safety
• Accessibility
• Site servicing

The type of permit depends on the work being proposed. A new building, an alteration to an existing building, and a tenant improvement may each follow a different path.

A building permit is required for the construction of a new commercial, multi-family, industrial, or public building in Nanaimo. Depending on the size and use of the building, different application requirements may apply for Part 3 and Part 9 buildings.

For existing commercial, multi-family, industrial, or public buildings, a commercial alteration permit is required for interior or exterior alterations and additions.

A leasehold improvement permit applies to alterations within a leased commercial space. This permit path applies to work within the leased space. If the work extends beyond the leased space or involves a change of occupancy type, the City directs applicants to the commercial alteration process instead.

Depending on the project, additional permits or forms may also be required for plumbing, demolition, signage, building envelope repair, geotechnical reports, or other project-specific requirements.

The application requirements depend on the type of project, the building classification, and the level of professional involvement required.

For commercial, multi-family, industrial, and public buildings, the City provides forms and information sheets related to commercial building permit applications, including:

• Occupancy approval requirements
• Occupant load calculation forms
• Part 3 commercial, multi-family, and industrial building permit checklist
• Part 9 commercial, multi-family, and industrial building permit checklist
• Pre-engineered steel building checklist
• Tenant improvement building permit application checklist

A building permit application may include:

• Building permit application forms
• Appointment of Agent form, when applicable
• Architectural drawings
• Structural drawings
• Mechanical drawings
• Electrical drawings
• Civil drawings
• Site plans
• Building code review information
• Energy documentation
• Letters of assurance
• Servicing information
• Geotechnical reports, where required
• Permit fees
• Deposits, bonding, or securities

The documents need to be complete. They also need to reflect the same project scope. If one drawing set is based on an older layout, or if servicing information does not match the site plan, the review process can slow down.

The building permit process should be considered before the application is submitted, especially when a project depends on other approvals.

While the exact path depends on the project, the process often includes:

Identify whether the work is new construction, an alteration, a leasehold improvement, demolition, plumbing work, signage, or another permit type.

Confirm whether zoning, development permits, variances, servicing approvals, or off-site works may affect the project.

Gather the required City forms, drawings, checklists, professional documents, fees, and supporting information.

The City’s online building permit application applies to both residential and commercial building permits. If the applicant is acting on behalf of the owner, the Appointment of Agent form must be completed first and attached.

After submission, the City may request clarification, revisions, or additional documentation before the permit can move forward.

Fees, deposits, bonding, securities, servicing requirements, or other permit conditions may need to be addressed before the permit is issued.

Building permit delays often come from missing, incomplete, or unresolved information

Common issues include:

• Missing application forms
• Incomplete drawings
• Consultant documents that do not match
• Required checklists not completed
• Proposed use or density not matching the zoning
• Rezoning, development permit, or variance requirements still unresolved
• Off-site works or servicing requirements not approved
• Fees, deposits, bonding, or securities not accounted for
• Project changes after submission

The City notes that incomplete online applications may lose their place in the queue or require a new application.

Building permit timelines vary based on the size and complexity of the project.

For commercial work in Nanaimo, the City states that tenant improvement and smaller commercial permit applications without a development permit or off-site works and services have an eight-week processing time.

Larger commercial permits vary from project to project, especially when development permits or off-site works and services are involved. The City recommends a pre-application meeting with Planning and Building representatives for larger projects.

Some simple tenant improvement applications may qualify for the Fast Track Building Permit Program, which was created to move simple tenant improvement permit applications through the process in as little as 15 business days, provided the application is complete and the project fits the program.

For developers, the building permit is only one part of getting a project ready for construction. The larger challenge is understanding how it connects to zoning, servicing, consultant coordination, site conditions, fees, bonding, inspections, and the construction schedule.

With decades of construction experience in Nanaimo and across Central Vancouver Island, Westmark helps developers understand what needs to happen before a project can move forward. Our team looks beyond the permit application itself and helps identify the practical details that can affect cost, timing, and approvals.

That can include:

• Reviewing site access and construction logistics
• Identifying servicing or frontage considerations early
• Coordinating construction planning with consultant drawings
• Understanding where permits, inspections, fees, bonding, and deposits may affect timing
• Recognizing when zoning, development permits, variances, or off-site works may need to be addressed
• Helping developers move from planning into construction with fewer surprises

For developers who are new to Nanaimo or building on Vancouver Island from outside the region, this local guidance can be especially important. Municipal requirements, site constraints, servicing expectations, and construction conditions can vary from one property to another. Westmark helps bring those details into focus early, giving developers a clearer path through the process and into construction.
