Executive Summary: Key Legal and Evidentiary Issues

• The Alberta Court of Appeal considered whether two separately approved development permits on a single lot must be assessed for their combined site coverage.
   
• Justice Feehan examined competing interpretations of section 687(3) of the Municipal Government Act on discretionary development authority.
   
• Davach Properties argued that a permitted-use approval cannot later be recharacterized as discretionary based on cumulative site coverage effects.
   
• Kathleen and Michael Harvey sought permission to appeal two Subdivision and Development Appeal Board decisions covering a row house and a backyard housing structure.
   
• Questions arose over whether the Board erred by refusing to hear the two development permit appeals together or sequentially.
   
• Permission to appeal was ultimately granted on three proposed questions of law and jurisdiction.
   

Facts of the case

Kathleen and Michael Harvey sought permission to appeal two decisions of the Edmonton Subdivision and Development Appeal Board (the Board): the row house decision (2026 ABESDAB 10046) and the backyard housing decision (2026 ABESDAB 10058), both concerning developments proposed by Davach Properties Inc on a single lot in Edmonton's Glenora community. The row house permit was approved on January 14, appealed on February 4, heard on March 5, and decided by the Board on March 10, 2026, upholding a four-dwelling row house with three secondary basement suites. The backyard housing permit was granted on February 2 and appealed on February 23. Between these two decisions, the Board issued a postponement decision — the source document lists two different dates for it: paragraph 8 states it was "heard on March 10," while paragraph 4 describes it as "dated March 31, 2026"; the document does not reconcile this discrepancy. That decision postponed the backyard housing hearing to April 29, 2026, to allow notice to residents of a proposed site coverage variation. The backyard housing application was then heard on April 29 and decided on May 12, 2026, upholding a two-dwelling structure above a garage. In the row house proceeding, the Board found the principal building's site coverage at 33.6%, below the 45% maximum, and declined to factor in the not-yet-heard backyard housing application. By the time of the backyard housing hearing, counsel for Davach Properties acknowledged that combined site coverage reached 45.7%, exceeding the regulatory cap by 4.9 square metres. The Board ultimately fixed overall site coverage at 45.7% (among measurements ranging from 45.25% to 48.4%), requiring a 0.7% variance, but found the excess "de minimus" and without negative neighbourhood impact, denying that appeal.

Policy and legislative provisions at issue

The applications turned on the Municipal Government Act, RSA 2000, c M-26. Section 685(3) provides that no appeal lies from a development permit for a permitted use unless the land use bylaw was relaxed, varied, or misinterpreted, or the application was deemed refused. Section 687(3)(a.3) requires the Board to comply with the land use bylaw, while section 687(3)(d) allows the Board to approve non-compliant development where it would not unduly interfere with neighbourhood amenities or materially affect neighbouring land use, enjoyment, or value, provided the development conforms to the prescribed land use. The Harveys also relied on the Edmonton Zoning Bylaw 20001, sections 7.100.1.1.8 and 7.110.3.4 and 3.5, governing site coverage calculations for permitted uses in the small-scale residential (RS) zone.

Reasoning and analysis

Justice Feehan applied the established test for permission to appeal a Board decision: a reasonably arguable point of law or jurisdiction that could affect the result, a question of sufficient importance to merit further appeal, and a reasonable chance of success, drawing on prior Court of Appeal authority including Carleo Investments Ltd v Strathcona (County) and Conley v Calgary (City). The Harveys argued that where two permitted-use development permits on one lot individually comply with site coverage limits but collectively exceed the 45% maximum, proper statutory interpretation requires the Board to treat both applications as discretionary developments under section 687(3), and that the Board had erred by refusing to consolidate or jointly hear the two appeals despite awareness of the cumulative effect. Davach Properties countered that each development permit gives rise to a separate right of appeal, that the relevant question is bylaw compliance at the time each permit issued, and that the Harveys had improperly conflated the bylaw concept of a "discretionary development" with the Act's concept of a "discretionary use," since a development cannot simultaneously be both a permitted and a discretionary use. Justice Feehan found the dispute raised genuine questions of statutory interpretation and jurisdiction extending beyond the immediate facts, with implications for future Board decisions involving multiple developments on a single lot.

Ruling and overall outcome

Justice Feehan concluded that the questions raised were of sufficient importance and had a reasonable chance of success, and granted the Harveys' — the successful applicants' — request for permission to appeal both the Board's March 10, 2026 row house decision and its May 12, 2026 backyard housing decision. Three issues were approved to proceed jointly before the Court of Appeal: whether the Board erred in refusing to consolidate or jointly hear the two development permit appeals; whether it erred in failing to apply the zoning bylaw's site coverage provisions to the two contemporaneous permits; and whether it erred in interpreting and applying section 687(3) of the Municipal Government Act. As an application for permission to appeal, this decision did not involve any monetary award, costs, or damages — none were sought, ordered, or discussed in the reasons.
