Plans Examination

Step 1 - Zoning Examination Process

The Zoning Examination Process ensures all permits meet Township standards under the Zoning By-laws.  This includes proper setbacks from property lines, percentage of lot coverage, land uses, etc.  Zoning By-laws protect existing and future land owners from unauthorized development which may harm existing or future development in the area. The initial review ensures that requirements under all by-laws are satisfied.  If not, major changes in building location or use may be required. There is often communication with the owner at this stage to clarify the use, building location, size, parking requirements, etc.  If the proposal does not meet Zoning By-law requirements, the owner may either change the proposal or alternatively, may make application through the Planning Division for a Minor Variance through the Committee of Adjustment or apply for a Zoning By-law amendment.

At this stage, a determination is made on whether the project and/or property is subject to the Oak Ridges Moraine Conservation Plan.  If it is, an application must be made to the Planning Department to enter into a Site Plan Control Agreement. Contact the Planning Division for further information at 905-833-5321 or email

Where applications deal with a subdivision, the Subdivision Agreement must be reviewed to ensure all plans and drawings comply.​

Step 2 - Architectural Plans Examination Process

The Architectural Plans Examination Process ensures the review of plans for fire safety, structural integrity and health aspects. The main purpose is to determine compliance with the Ontario Building Code and other applicable laws. An typical review examines a building for compliance with either Part 3 or Part 9 of the Ontario Building Code.  The examiner may refer to other sections of the Building Code standards such as; Canadian Standards Association  (CSA), Underwriter Laboratories of Canada (ULC), and laws related to the Fire Code.

Step 3 - Structural Plans Examination Process

The Structural Plan Examination Process ensures that all plans and specifications meet structural standards.  A typical review examines a building for compliance with Parts 4 and 9 of the Ontario Building Code.

Step 4 - Mechanical Plans Examination Process

The Mechanical Plans Examination Process ensures that all plans and specifications meet good engineering practice.  A typical review examines a buildings' mechanical systems for compliance with Part 6, Part 7 and Part 9 of the Ontario Building Code.  Examiners interpret the heating, ventilating, air conditioning and plumbing regulations parts of the Building Code.

Certain Building Code related fire requirements, such as sprinklers, standpipe and hose systems, extinguishing systems for commercial kitchen exhaust hoods and industrial paint spray booths, are checked and information on shop drawings are reviewed prior to the work being installed.
