Yes — in most cases widening a driveway in Ottawa requires City approval. If the widening changes the curb cut or the portion of the driveway that crosses City right-of-way between the curb and your property line, you need a Private Approach permit from the City of Ottawa, which in 2026 typically costs in the range of $250–$600 depending on approach type and whether curb work is involved. Even if you only widen the portion entirely on your own property and leave the curb cut untouched, you still have to comply with the Zoning By-law's maximum driveway width and minimum front-yard soft-landscap...
The strip of driveway between the street curb and your front property line is not yours — it sits in the City's right-of-way, and any change to it requires a Private Approach permit from the City of Ottawa's Right of Way department. That means you need the permit if you are widening the curb cut, adding a second driveway entrance, changing the driveway's location along the frontage, or altering the depressed curb in any way. Applications ask for a site sketch showing the proposed approach width ...
Widening only the on-property portion of the driveway and leaving the existing approach and curb cut unchanged usually avoids the Private Approach permit — but zoning width and landscaping limits still apply, and the City can still order you to remove non-compliant paving.
Ottawa's Zoning By-law regulates driveway width, parking-space location, and front-yard landscaping, and these are the rules that most often block a widening project. In typical low-rise residential zones a driveway serving a detached home is limited by both a maximum width in metres and a maximum percentage of the front yard that can be covered by hard surface — commonly no more than about 50 percent of the front yard, with the remainder required to be soft landscaping such as sod, garden beds,...
Permeable pavers are attractive but generally still count as driveway surface for zoning width purposes. Do not assume they exempt you from the front-yard soft-landscaping minimum — confirm with the City's planning staff before you design around it.
Cost depends entirely on surface and how much excavation and base work the widened strip needs. In 2026, adding asphalt in Ottawa runs roughly $12–$18 per square foot for a properly excavated and compacted granular base with new asphalt, so widening a 40-foot driveway by 4 feet (160 sq ft) typically costs about $1,900–$2,900. Concrete runs higher at roughly $18–$28 per square foot, putting the same widening around $2,900–$4,500. Interlock and permeable pavers are the premium option at about $25–...
The reason a widened driveway cracks along the joint within three winters is almost always base preparation, not the asphalt itself. Ottawa's freeze-thaw cycling and heavy clay soils demand a proper granular base: typically 8 to 12 inches of compacted Granular A or B over a geotextile fabric, with the sub-base excavated to full depth rather than the new strip simply being laid on scraped topsoil. Skimping here is the single most common shortcut in low-ball driveway quotes. Drainage is the other ...
Before any excavation, a free Ontario One Call locate is required by law. It takes several business days, so schedule it early. Gas, hydro, telecom, and water services often run through the front yard exactly where driveway widening happens.
Do this in order and the project goes smoothly. First, look up your zoning and confirm the maximum driveway width and front-yard landscaping requirement for your specific lot. Second, if the curb cut or right-of-way portion is changing, submit the Private Approach permit application and allow several weeks. Third, request three itemized quotes from Ottawa driveway contractors specifying surface material, excavation depth, base material and thickness, compaction, edge restraint for pavers, draina...
Yes, if the widening changes the curb cut or the portion of the driveway in the City right-of-way between the curb and your property line — that requires a Private Approach permit from the City of Ottawa, typically $250–$600 in 2026. If you're only widening on your own property and not touching the approach, you don't need that permit, but you must still meet zoning width and front-yard landscaping rules.
It depends on your zone and lot frontage. Residential private approaches are commonly capped around 6 metres, and the Zoning By-law also limits the share of the front yard that can be hard-surfaced — often no more than about 50 percent, with the rest required as soft landscaping. Check your specific zone using the City's GeoOttawa mapping tool.
In 2026, asphalt widening runs about $12–$18 per square foot, concrete about $18–$28, and interlock or permeable pavers about $25–$40. Widening a 40-foot driveway by 4 feet (160 sq ft) typically costs roughly $1,900–$2,900 in asphalt or $4,000–$6,400 in interlock. Curb cutting adds another $1,200–$3,000.
No. Parking in the front yard outside a legally established driveway — on grass, gravel, or an unapproved pad — violates the Zoning By-law and the City enforces it on complaint. Widening the driveway legally is the correct fix if you need more parking.
Typically two to six weeks from application to approval, longer during the busy spring and summer construction season. Apply before you book your paving contractor so the permit isn't the thing holding up the job.
