Use the official City of Oshawa Zoning By-law and Planning resources linked below for authoritative requirements and current forms.[1]
Overview of commercial and industrial zones
The City of Oshawa regulates land use through its consolidated Zoning By-law which sets permitted uses, lot standards, setbacks, building heights and parking requirements for commercial and industrial zones. Common categories include centres for retail and offices, light industrial uses, and heavy industrial uses; each category carries different site and buffering rules. For precise zone maps and definitions consult the City of Oshawa Zoning By-law and mapping resources.[1]
- Retail and service uses (shops, restaurants, offices)
- Light industrial uses (warehousing, distribution, light manufacturing)
- Heavy industrial uses (manufacturing with higher impacts, subject to separation distances)
- Accessory uses (parking, loading, signage, outdoor storage conditions)
Permits, approvals and development process
Most commercial and industrial projects require one or more of the following municipal approvals: zoning conformity check or zoning clearance, site plan approval, building permits, and business or licensing approvals. Complex redevelopment may also require servicing permits, stormwater approvals and environmental studies.
- Zoning clearance or compliance letter prior to building permit application
- Site plan control approval for new buildings or major changes
- Building permit for construction, change of use, or renovations
- Development charges and applicable fees
