What the zone permits
The permitted uses and regulations for R1 are set out in Section 15.1, Zoning By-law 05-200. HamiltonIQ does not paraphrase them: an exception, a holding provision or a later amendment can change what applies to one lot. The City of Hamilton’s Zoning Verification Report Application is the City of Hamilton’s own answer for a property. The interactive zoning map shows the zone on a single lot.
