RM3 zone polygons (By-law 2020)The outline is the City of Burlington boundary.

The 8 smallest polygons are too small to see at this scale and are not drawn; every polygon is counted.


Where RM3 applies

Polygons and hectares by the City of Burlington’s planning community outlines, each polygon placed by a point inside it.

Wards: Ward 6 (9), Ward 4 (8), Ward 1 (6), Ward 2 (4), Ward 5 (4).


Exceptions, holding and other markers

The markers the layer records on RM3 polygons. Their terms are written only in the by-law; each line says where.

Exception (30 polygons)
138 (×3), 253 (×3), 142 (×2), 30, 47, 102, 104, 108, 123, 143, 149, 150, 151, 157, 172, 173, 178, 192, 441, 491, 513, 550, 558, 563, 564Part 1, s. 1.5: a dash and a number after a zone designation (e.g. RH4-10) is an exception number; the special provisions are set out in Part 14, Exceptions to Zone Designations.
Holding (H) prefix (4 polygons)
H (×4)Table 1.4.1 lists the Holding Zone as an H prefix; the holding provisions are in Part 11.

What the zone permits

The permitted uses and regulations for RM3 are set out in Part 2, Residential Zones, Zoning By-law 2020. BurlingtonIQ does not paraphrase them: an exception, a holding provision or a later amendment can change what applies to one lot. The City of Burlington’s Zoning Clearance Certificate is the City of Burlington’s own answer for a property. The interactive zoning map shows the zone on a single lot.
