Development permit
Rocky View County Planning and Development (Development Authority)
Land Use Bylaw C-8000-2020 (section 90) requires a development permit for all development except what Table 2 (section 92) exempts. Table 2 exempts an accessory building in an Agricultural or Residential District when it meets that district's parameters for a permitted use, and general agriculture where it is a permitted use, provided nothing needs a variance. Anything larger, taller or closer to a property line than the district allows needs a permit. Once an application is acknowledged as complete, the Development Authority must decide within 40 days; a permit takes effect 21 days after public notice (barring an appeal) and lapses after one year if work has not started.
