Overview of Zoning Districts

Zoning districts group land by primary use and standards such as permitted uses, building height, setbacks, density, lot coverage and parking. Typical district families used in London include residential, commercial, industrial, institutional and open space designations; each family contains specific district codes with rules in Z.-1.

  • Residential districts: single-detached, semi, townhouses, apartment zones.
  • Commercial districts: neighbourhood, mainstreet, service and regional centres.
  • Industrial districts: light, general and heavy industrial classifications.
  • Institutional and open space districts: schools, parks, community uses.

Interpreting Zoning Maps

Zoning maps show the district code assigned to each parcel; the code links to the text in Z.-1 for permitted uses and numeric standards.

Variances, Minor Adjustments and Site Plan

Where a proposed use or dimension does not meet Z.-1 standards, applicants may seek relief through the Committee of Adjustment (minor variances) or a zoning amendment. Major development typically requires site plan approval and may require plan of subdivision review.
