In addition to the completed application form, applicants must also submit sketches, building drawings, plans and other documents to the municipality for processing.

For exterior work, a floor plan, a cross section, a site plan and elevations will be required.

For interior work, a floor plan and a cross section drawing will be required. Buildings that are over 3 stories or greater than 600 square metres will require an architect or an engineer to design and prepare plans for the building.

Building Permit Fees - The Building Permit fee is determined by the square footage of the project and is paid at the time Building Permit is issued.

All Development Charges are payable at issuance of building permit.

Additional fees for services such as water, parkland dedication, development charges, and deposits for protection to public property may also be required.

Building Codes - Standards
The use of Building Permits allows municipalities to regulate the types of construction in the community and ensure that proper building standards are met. The enforcement of building codes serves to protect the health, safety and welfare of the public.

Review Process 
Applications are processed as quickly as possible depending on the complexity of the application, the completeness of drawings and information submitted and if referral to other departments is required. 

If a zoning change or minor variance is necessary, or if building plans must be altered to comply with the building codes, then the changes must be approved before a Building Permit can be issued.

Upon approval of the proposed construction, a Building Permit is granted to the applicant.

The construction must proceed as approved in the review process.

There will be inspections required for the project which will be conducted by the Building Inspector at each major phase of the construction.

The Inspector's duty is to ensure that the project is being carried out according to the Building Code, the Building Permit and the approved building plans. The individual responsible for the project must request each inspection with 24 hours advance notice given to the Building Inspector. If the Building Official finds, upon inspection, that some work does not conform to the approved plans or code, the owner will be advised (possibly with written notice) that the situation is to be remedied. If the violation is deemed serious enough, the Building Official may post a stop-work order which will be in effect until the problem is resolved. If work on the project continues without resolution of the problem, legal action may be taken against the builder/owner. 

The builder must also bring any proposed deviations from the original plan to the attention of the Building Official so that they be approved or rejected in the same manner as the original building plans.
