PC-NHS1 zone polygons (By-law 2010-0050)The outline is the Town of Halton Hills boundary.

The 21 smallest polygons are too small to see at this scale and are not drawn; every polygon is counted.

Where PC-NHS1 applies

Polygons and hectares by the Town of Halton Hills’ outlines, each polygon placed by a point inside it. 110 zone polygons fall outside every outline.

Wards: Ward 2 (88), Ward 1 (22).

Exceptions, holding and other markers

The markers the layer records on PC-NHS1 polygons. Their terms are written only in the by-law; each line says where.

Site-specific exception (12 polygons)
34 (×8), 91 (×2), 52, 53Section 2.5: a number in brackets after a zone symbol refers to a site-specific exception listed in Part 13.
Holding provision (97 polygons)
H2 (×94), H1 (×2), HSection 2.6: where a zone symbol is followed by (H), no use other than the existing one until the (H) is removed; holding zones are detailed in Part 14.

What the zone permits

The permitted uses and regulations for PC-NHS1 are set out in Part 10 of Comprehensive Zoning By-law 2010-0050 (PDF, Town of Halton Hills). HaltonHillsIQ does not paraphrase them: an exception, a holding provision or a later amendment can change what applies to one lot. The Town of Halton Hills’ Compliance Memo Request is the Town of Halton Hills’ own answer for a property. The interactive zoning map shows the zone on a single lot.
