Decks and porches in Stittsville
A rear deck is the simplest way to add outdoor space in Stittsville, and decks from the 1980s and 1990s may now be due for rebuilding. Low decks under 600 mm can be built without a permit unless they are the main entrance; raised decks need one, and porches larger than 10 square metres generally do.

Homes in Stittsville
What the local housing means for decks and porches.
The village was founded in the 1850s and rebuilt around the railway after an 1870 fire. Its Main Street core still has 19th-century buildings, and the City adopted a design plan for it in 2015. The suburban subdivisions around it date from the mid-1980s onward, and population growth suggests the largest share was built since 2000.
- Most Stittsville homes appear to be under 40 years old, so original builder-grade kitchens, bathrooms and basements are a typical starting point.
- Older houses near Main Street can need deeper kitchen, bathroom and addition work than the suburban homes around them.
- About 30 percent of townhomes are rented, which supports basement suites and rental-ready updates.
Permits and approvals
What to check in Stittsville before decks and porches work starts. Rules change, so we confirm what applies to your address.
Mississippi Valley Conservation Authority
Poole Creek and Feedmill Creek are tributaries of the Carp River, managed by the Mississippi Valley Conservation Authority. Poole Creek's headwaters are in a provincially significant wetland near Highway 7 and Hazeldean Road. Additions and alterations in a regulated area need an MVCA permit before the building permit, and MVCA approved new Carp tributary hazard maps in July 2026.
Main Street
No heritage conservation district covers Stittsville, but the Stittsville Main Street Community Design Plan guides the corridor, and at least one building on it, Green's Hotel, is individually designated. Exterior work on a designated building needs heritage approval and loses the usual permit exemptions.
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.
Trees
On urban lots of one hectare or less, the City's Tree Protection By-law requires a permit to remove or injure a distinctive tree, which the current by-law sets at 30 cm or more across at chest height. Footings and trenches near big trees are planned around their roots. The thresholds have changed in recent years, so we check the by-law in force.
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.

Good to know
How much does a deck or porch cost in Stittsville?
A cedar raised deck of about 240 sq ft typically comes to $21,200 to $27,800 with HST, based on published Ottawa and Ontario price guides checked October 2026. With pressure-treated decking the same job is about $16,400 to $21,500; with composite decking, about $27,900 to $36,600. Size, the state of the house and what you add all move the number, so use the estimator for your own project. A firm quote follows a site visit.
My house backs onto Poole Creek. What does that change?
If your lot is in the Mississippi Valley Conservation Authority's regulated area, an addition or alteration needs an MVCA permit before the City building permit, which MVCA says takes about 30 days. We confirm decks and interior work with MVCA, and check the mapping for your address.
Do you work on the older houses near Main Street?
Yes. Older houses there usually need more investigation before a renovation, so the estimator's older-house allowance is worth switching on, and we check for designated buildings before exterior work.
