A development application is a formal submission to a municipality requesting approval for a proposed development project. Applications may seek various approvals depending on what's proposed: official plan amendments to change land use designations, zoning bylaw amendments to permit different uses or building sizes, subdivision approval to create new lots, site plan approval for building design and layout, or minor variance to deviate slightly from zoning rules. Applications include detailed plans, studies, and supporting documentation demonstrating compliance with regulations and addressing community impacts. Staff review applications for technical compliance, public consultation typically occurs, and elected officials or designated bodies make decisions. The application process can take months to years for complex projects, involving multiple rounds of revision and public input.
