Published fee information

City-issued 2026 simplified fee schedule, p.7: if a residential accessory shed actually requires a permit, its building permit rate is $0.46/ft² of chargeable area (minimum $143), with $25 separate accessory-structure zoning review. Qualifying detached storage-only sheds no more than 15 m² with no plumbing may be exempt from a building permit; a fee is not charged for an exempt project. Verify zoning and siting.

Use this as a municipal-fee reference, not as the total project budget. Design, engineering, related applications and construction costs are separate.
