Driveway questions Ottawa homeowners actually ask

The by-law changes most Ottawa advice has not caught up with

Three things changed in 2026 and a great deal of driveway advice circulating in this city still describes the old position. Access By-law 2026-139 took effect on 8 April 2026, replacing By-law 2003-447, and it now explicitly permits permeable surfaces to absorb stormwater. Zoning By-law 2026-50 was enacted on 11 March 2026, replacing 2008-250, and it is the document that caps driveway width at 6 m in Zones A to C and at 50 percent of lot width in Zones D to F. Separately, a Hardscaping Contractor Licence became mandatory on 1 March 2026. Alongside those, the long standing rules still apply: a private approach must be between 2.4 m and 9.0 m wide and cannot exceed 50 percent of your frontage, at least 50 percent of the front lawn must remain soft landscaping, and artificial turf does not count toward that. The permit free extension of 1.8 m or less carries four conditions and specifically cannot be asphalt, which is the single most common misunderstanding we hear.

Questions about timing and the Ottawa season

The practical paving window here is early May to mid October, and the constraint is not the calendar. OPSS 310, the Ontario standard for hot mix paving, contains no calendar restrictions whatsoever. What it contains are temperature conditions: at least 7 C and rising for a surface course, at least 2 C and rising for a binder course, no frozen roadbed underneath, a dry surface to pave onto, and the work completed by half an hour after sunset. Those conditions simply happen to be satisfiable in Ottawa for about five months of the year.

The front end of the season has a second gate. Local asphalt plants close for the winter and reopened in the first week of May in 2026, so before that there is no hot mix to buy at any price. Spring load restrictions overlap with it, typically from early March to mid May at roughly 5 tonnes per axle, because thawing roads cannot carry heavy vehicles. Those are the same trucks that deliver aggregate and hot mix, so a March start is not a scheduling preference, it is a legal impossibility for the material supply. The City sets the dates each year from a thaw index rather than fixing them, so they shift.

At the back end, the limit is the same temperature rule read in reverse. A late October or November day that reaches 7 C briefly at noon is not 7 C and rising, and a mat that goes down too cool cannot be compacted properly, which means it will ravel early regardless of how good the base underneath it is.

Questions about permits and the 2026 by-laws

You do not need a City of Ottawa access permit to resurface an existing driveway at its existing size. That covers the majority of residential work, including remove and repave. You do need one for a new access or for widening an existing one, and that is $193 for a residential property with six to eight weeks of processing time. A culvert inspection, where a rural entrance crosses a ditch, is $112. A road cut permit, if the work requires cutting the City's pavement, is $296 per street segment. Commercial access permits scale with parking count: $334 for 1 to 49 spaces, $669 for 50 to 99 and $853 for 100 or more.

Width is governed separately. A private approach must measure between 2.4 m and 9.0 m and cannot exceed 50 percent of your lot frontage. Current zoning caps driveway width at 6 m in Zones A to C and at 50 percent of lot width in Zones D to F. At least half of the front lawn must remain soft landscaping, and artificial turf does not count toward that requirement.

There is one exemption people ask about constantly. A widening of 1.8 m or less can be done without a permit, but it must satisfy all four of the stated conditions and it specifically cannot be asphalt. That last point catches people out, because the most common widening request in this city is a wider asphalt driveway, and that always needs the permit.

The paperwork changed recently. Access By-law 2026-139 replaced 2003-447 on 8 April 2026 and now explicitly permits permeable surfaces to absorb stormwater. Zoning By-law 2026-50 replaced 2008-250 on 11 March 2026. And a Hardscaping Contractor Licence became mandatory on 1 March 2026. Outside the city boundary, in Rockland, Embrun, Russell, Carleton Place and Kemptville, none of the City of Ottawa process applies at all and the local municipality approves the entrance instead.

Questions about money

Asphalt in the Ottawa market runs $5 to $10 per square foot new, with a typical double landing between $3,000 and $6,000. Remove and repave is $8 to $14, with a standard double commonly $4,800 to $8,500. An overlay on a base that is still sound is $2.50 to $6. Interlock is $20 to $35, which puts a typical double-car interlock driveway at $8,000 to $18,000. Plain concrete is $9 to $18, so 600 square feet is $5,400 to $10,200, and stamped concrete is $18 to $30. Tar and chip is $2 to $5 and gravel $1 to $4.

Maintenance is where the arithmetic gets interesting. Sealing is $0.25 to $0.55 per square foot, which is roughly $150 to $350 on a 600 square foot double. A crack repair visit is $200 to $500. Set those against a $6,500 repave and the value of catching a driveway before the base is involved becomes obvious.

Small driveways cost more per square foot, and this is not a markup. Published Canadian size tiers run $10 to $15 per square foot at 100 to 500 square feet, $8 to $12 at 501 to 1,000 and $6 to $10 at 1,001 to 5,000. A crew, a paver and a roller mobilise the same either way, and hot mix is sold by the tonne with a minimum load, so a small job often pays for material it cannot physically use.

Questions about looking after what you have

Do not seal new asphalt. It needs 6 to 12 months to cure first, while the lighter oils in the binder oxidise and evaporate. Sealing early traps them, stops the sealer bonding and leaves a soft surface that scuffs under a turning wheel. A driveway paved in July should have its first seal the following season.

After that first seal, the correct interval is every two to three years, not annually. Over sealing builds a thick brittle layer that cracks and peels off in sheets, and the driveway ends up looking worse than if it had been left alone. Sealing season runs roughly late May to early October and needs temperatures above 10 C. After a seal, stay off it for 24 to 48 hours before parking on it or turning wheels on the surface. Concrete is different again, resealing at intervals of five years or more.

Crack sealing is the highest value thing you can do, because it is the only intervention that stops water reaching the base. Once water is in the granular and freezing, ice lenses form, the surface lifts, and when the thaw arrives the subgrade temporarily loses bearing capacity. That is why Ottawa driveways fail in March rather than January, and why the repair stops being a surface job at that point.
