Old Aurora lots routinely run 200 ft deep - the longest average rear-yard depth of any town in York Region. That depth is why Aurora is one of the few GTA municipalities where a two-storey garden suite with its own private yard still clears the angular plane without a minor variance. Aurora permits additional dwelling units with the Aurora Village and Northeast Old Aurora heritage districts adding design review in the core.
Large mature lots in Old Aurora with 200 ft depths, and Oak Ridges Moraine constraints on the western edge. North-GTA snowfall of 148 cm and -5.1°C winters give Aurora a May-October working season - foundations for adu building permit go in before the ground closes, with interior finishing carried through the cold months.
The permit is the whole project's critical path in Aurora: nothing is ordered and no crew is scheduled until the application clears, and approvals here run $8,500-$14,000 including York Region charges. We prepare and submit the application, answer the plans-examination comments, and carry the file through zoning, building and - where the lot needs it - Committee of Adjustment, with York Region as the reviewing authority. Approvals are quoted separately from construction on every contract we write, so a fee increase at York Region is visible rather than buried in a build number.
