Landscape design plans
A measured plan for the whole property before anybody digs, with grading, planting and hard surfaces resolved on paper.
Ottawa landscape design, costs and rules
What a plan and a build actually cost in 2026, the grading and locate rules you cannot ignore, the City's tree protection, and how clay, frost and road salt decide what will still be standing in ten years.
A measured plan for the whole property before anybody digs, with grading, planting and hard surfaces resolved on paper.
Taking a back garden from plan to finished space in one contract, in the order that stops the work being done twice.
A planting plan that survives an Ottawa winter, with soil depth, hardiness and the salt line taken seriously.
Getting water away from the house and off the lot without breaking the rules about where it is allowed to go.
Walls that hold back soil on a frost-heaving clay site, and the height at which a permit and an engineer become mandatory.
This site is operated by Wells DevOps in Ottawa. We do not install patios or plant gardens. We set out how landscape work is priced and regulated here, with every figure sourced, and pass your details to a local licensed contractor who quotes you directly.
Two rules surprise almost every homeowner. Requesting a locate through Ontario One Call before digging is mandatory, free and needs at least five business days. And you may not change the grading of your property: the City's own landscaping guide states it directly, along with the rule that water must follow approved drainage patterns and cannot be directed onto a neighbour.
Landscaping itself is not a licensed trade in Ontario. Anyone may call themselves a landscape designer. Only one title is protected: under the OALA Act, a full member of the Ontario Association of Landscape Architects may use the designation Landscape Architect and it is an offence for anyone else to do so. For a retaining wall over a metre you need a building permit and a professional engineer's design, and that is a credential you can verify.
Then there is the ground. Much of the city sits on Champlain Sea clay, which drains slowly and heaves with frost, and the Building Code puts foundation depths as much as 1.2 m below grade in clay soils. Every patio base, every wall and every drain on this site is priced with that in mind, and the salt thrown two to three metres from every driveway between December and March is why the plant list changes near hard surfaces.
Indicative ranges
Indicative 2026 ranges before HST. Design fees, sod, seeding and paver rates come from published 2026 cost guides. The retaining wall, step, engineering, grading and swale figures are market ranges with no primary source and should be treated as a starting point for a written quote rather than a price.

The three rules that stop a landscape project: the mandatory locate, the City's tree protection, and the fact that you may not change your grading.
