Homes in Greely
What the local housing means for decks and porches.
The population rose from about 4,100 in 2004 to about 5,430 by the end of 2010, with the City issuing an average of 81 building permits a year from 2001 to 2010. Almost all homes are single-detached, and most lots are between half an acre and two acres.
- Because nearly every lot is on a well and septic system, a secondary suite is limited to one additional unit, and new bedrooms or bathrooms start with a septic check.
- Large lots leave room for additions, decks and porches, placed around the well and the septic bed.
- Homes near Shields Creek, the Osgoode Marsh or other wetlands can sit inside a conservation authority's regulated area.
Permits and approvals
What to check in Greely before decks and porches work starts. Rules change, so we confirm what applies to your address.
Conservation authority
South Nation Conservation describes Shields Creek as lying within Greely, in a subwatershed that drains to the South Nation River, so it is likely the authority for most of the village; we check both authorities' mapping by address. SNC permits are needed for development in floodplains, on unstable slopes, in wetlands and within 30 m of a wetland. The 2012 community design plan sets a 30 m setback on each side of Shields Creek and protects the Osgoode Marsh; we confirm whether it applies to a given lot.
Decks and porches
An attached deck needs a building permit when its surface is more than 600 mm (about 24 inches) above the ground, or when it is the main way into the house. A freestanding deck needs one when it is larger than 10 square metres (about 108 sq ft) and more than 600 mm up. Porches generally need a permit when they are larger than 10 square metres.
Zoning
Additions and larger decks have to meet the zoning setbacks, height and lot coverage for your lot. Most of Ottawa's new Zoning By-law 2026-50 is in force (the parts not under appeal took effect from March 2026), and where a provision is still under appeal the stricter of the old and new rules applies, so we check the rules for your address before design starts.
