Do eaves, balconies or other projections count toward setbacks?
Some building elements can extend into required setbacks, including qualifying eaves, roof overhangs, gutters, steps and ramps. Additional specified elements are allowed within side and rear setbacks. Balconies are not listed as an allowable setback encroachment.
Certain building elements can extend into the required setback without being treated in the same way as the main building. These include:
- eaves or roof overhangs up to 600 mm;
- fascias, gutters, downpipes, light fittings and sun blinds;
- landings, steps or ramps that are no more than 1 m above finished ground level; and
- for side and rear setbacks only, certain additional elements such as rainwater tanks, clotheslines, hot water systems, chimneys, heating or cooling appliances, utility meters, unroofed pergolas, solar inverters and batteries.
Balconies are not included in the listed allowable setback encroachments, so they should not automatically be assumed to be permitted within the required setback.
