Permit Works helps Markham homeowners, contractors and business owners prepare permit-ready drawings, review zoning requirements, coordinate required consultants and organize building permit applications for submission through the City of Markham’s ePLAN system.
The City of Markham’s Building Standards division reviews building permit applications for construction, demolition, additions, renovations, structural alterations, changes of use and other regulated work. Whether a permit is needed depends on the project scope, existing conditions and applicable law.
Markham requires building permit applications to be submitted electronically through ePLAN. The submission generally includes application forms, drawings, supporting documents and applicable approvals suited to the project. Markham’s permit guides identify typical requirements for different application types, but not every project needs the same plans or consultant input.
Zoning and other applicable laws should be considered before the permit package is finalized. Markham conducts a pre-screen of uploaded material against its submission standards before the file proceeds as a permit application. During plan review, municipal staff may provide mark-ups or comments and request revised drawings or documents through ePLAN.
Permit Works can review the proposed work, prepare architectural permit drawings, coordinate structural or mechanical consultants where needed, and organize the application material. If municipal comments are issued, we can review them, update our work where required and help prepare a coordinated resubmission.
Markham zoning regulates matters such as permitted land and building uses, building size, height and location, setbacks, lot coverage, parking and other property-specific standards. These requirements can affect additions, decks, accessory structures, basement entrances, additional residential units and commercial projects.
Markham’s Comprehensive Zoning By-law 2024-19 is in force across most of the city, subject to remaining site-specific appeals, mapped exclusions and applicable transitional provisions. The property address, interactive zoning information, applicable schedules and exception provisions should therefore be checked together.
Reviewing zoning early helps determine whether the proposed use and building form fit the applicable rules before detailed permit drawings are completed. Markham also offers a Zoning Preliminary Review service for certain low-rise residential, multiple-residential and non-residential proposals.
If a proposal does not comply, the appropriate response depends on the property and the specific issue. The design may be revised, or an additional planning or zoning process may be needed. Not every project requires a minor variance, and zoning compliance should be assessed individually.

Permit Works supports residential and commercial permit projects throughout Markham, including Markham Village, Unionville, Thornhill, Cornell, Milliken and surrounding communities. Projects may include basement alterations, additional residential units, additions, decks, structural changes, tenant improvements and changes of use.
Property conditions vary across the city. Established neighbourhoods, newer subdivisions, mixed-use centres, employment areas and commercial plazas can be affected by different zoning provisions, site-specific exceptions, lot conditions and existing approvals. Heritage considerations, grading, tree protection, conservation authority requirements or other applicable laws may also be relevant to some properties and scopes of work.
Each project should be reviewed using its address and a clear description of the proposed work. Permit Works can examine the available information, identify likely zoning and permit considerations, and outline the drawings, consultant coordination and submission steps that may apply.
Permit requirements depend on the proposed work. Markham identifies many projects that require permits, including additions, structural wall changes, basement entrances, accessory apartments or additional residential units, new plumbing, changes of use and various renovation projects. Deck requirements can depend on height and other design conditions.
Some cosmetic maintenance and replacement work may not require a building permit when it does not affect structure, openings or regulated building systems. Electrical work is administered separately from the municipal building permit process.
The City’s general guidance does not cover every situation. Before construction starts, the property and full scope should be reviewed for Building Code, zoning and applicable-law requirements. Permit Works can help identify the likely application type and supporting documents.
Markham building permit applications are submitted online through ePLAN. Applicants create or access an account, request an application and upload the required drawings and documents. City staff conduct a pre-screen to check the submission against Markham’s standards before it proceeds as a permit application.
Plan review and required resubmissions are handled electronically. When reviewers complete a cycle, the applicant can access mark-ups and comments, revise the material and upload a coordinated response. Once the applicable requirements are resolved and the permit is issued, approved documents are downloaded through the system.
The time and number of review cycles vary with project type, completeness, zoning, applicable-law approvals, consultant coordination and municipal comments. No particular approval date can be guaranteed.
Drawing requirements vary by application type. Depending on the project, the package may include a site plan, zoning summary, existing and proposed floor plans, elevations, building sections and construction details. Structural drawings may be required for additions, foundations, decks, wall openings, beams or other load-bearing work.
Some applications also require plumbing, mechanical or HVAC information, energy-efficiency documentation, grading information, or reports and drawings from other consultants. Commercial renovations and changes of use may need additional details addressing occupancy, exiting, accessibility, fire separations and building systems.
Not every project needs every document. Markham’s online Guides to Building Permits list typical forms, drawings and supporting documentation for each application category. The project scope and applicable guide should be reviewed before the package is prepared.
Permit Works may be able to assist when Markham Building Standards has issued ePLAN mark-ups, review comments or requests for additional information. The first step is reviewing the existing application, drawings, municipal correspondence and any consultant documents.
We can identify comments that relate to our architectural scope, assess zoning or documentation concerns and coordinate with structural, mechanical or other consultants where their response is required. We can then revise our drawings and help organize a clear resubmission.
We cannot guarantee that every existing application can be continued using its current documents. Professional responsibility, drawing quality, outstanding approvals and the status of the municipal file must be considered before Permit Works can determine how it may assist.
