Building & Engineering

The Town of Halton Hills’ Building & Engineering services help ensure construction and development are safe, compliant and well‑planned. Whether you are a homeowner, contractor or developer, this section provides information on permits, inspections, zoning and residential building requirements.

Our team reviews applications, issues permits, conducts inspections and supports projects from planning through completion — all while meeting Ontario Building Code and municipal standards.

Our counter is located on the lower floor of Town Hall and is accessible during regular hours of operation (excluding holidays) from 8:30 a.m. to 4:30 p.m. If you would like to meet with any of our Building staff in person, we recommend calling 905-873-2600 ext. 2300 before your visit to request an appointment to ensure their availability.

All fees for the blades are paid to F.L. Sign Inc.

Rural property owners are encouraged to erect the reflective green and white blades, which are easily identified by Emergency Response Personnel rather than municipal addresses of other colours or material.

Sign specifications:

  1. Flat aluminium or metal sign blank of (5”x16”) dimensions.
  2. White numbers (4” height) on green background
  3. Numbers and background to be made of Engineering grade retro-reflective traffic sign sheeting

Please note that your Rural Municipal Street Address should be attached to a post which is clearly visible from both sides of the street. Numbers should not be placed on your house as they may not be clearly visible from the street. The sign should be adjacent to your property line at your driveway.

In 2016, the Town of Halton Hills Mandatory Sewage Systems Maintenance Inspection Program (MSSMIP) was established and is included in the Building By-law 2025-0015.

The Ontario Building Code (OBC) requires properties which are identified in vulnerable areas to be subject to MSSMIP. Each sewage system within the defined areas must be inspected every five (5) years after the most recent inspection of the sewage system has been conducted.

The OBC also authorizes municipalities to accept a Certificate from the property owner as an alternative to conducting inspections under mandatory maintenance inspection programs. These certificates must be in a form approved by the Minister of Municipal Affairs and Housing and be signed by a qualified person [which can be a person with a Building Code Identification Number (BCIN) registered with the Ministry of Municipal Affairs and Housing (MMAH) for septic design, a Septic Supervisor (with BCIN), an Architect, or a Professional Engineer].

There are two compliance options available:

  • Option 1: Municipal Inspection
    All administrative, inspection, and enforcement processes will be delivered by municipal staff.
    To schedule an inspection with the Town and pay the associated fee, contact 905-873-2600 ext. 2043.
  • Option 2: Hybrid – Third Party Inspection
    Municipal staff will deliver administrative and enforcement services, and a third party/qualified person will inspect the sewage system and complete the Inspection Report and the MSSMIP Certificate. The certificate must be in a form approved by the Minister of Ministry of Municipal Affairs and Housing and must be signed by a qualified person.
    To submit the documentation either send via email to [email protected], submit in person at the Building Services counter at Town Hall, or via mail.
    To pay the associated fee, contact 905-873-2600 ext. 2043.

The inspection, either by the Town or Third Party, is to be completed by September 30th of the calendar year the inspection is required.
