Dearborn, MI Building Safety: Building Permits (2026)

Under Zoning Ordinance § 2.03(D)(1), a deck counts as an accessory structure and needs a building permit plus zoning-compliance review before construction, though § 2.03(D)(2)(c) exempts decks from the separate Zoning Board of Appeals approval other accessory structures need. Concrete patios and other flatwork are handled through § 2.20: you file a Zoning Compliance Certificate application with the building official, accompanied by a site plan showing the dimensions and depth of the proposed concrete. The general code's fee schedule, § 9-33b, sets the patio compliance-certificate fee at $8 per 100 square feet, minimum $100.
