Washington DC exempts single garden storage sheds under 50 square feet and under 10 feet in height from building permits. Larger sheds require a building permit from DOB. All sheds must comply with zoning setback and lot coverage requirements.
Washington DC's Department of Buildings (DOB) requires building permits for most accessory structures, with a specific exemption for small garden sheds. Under DC Code Section 107.3.3, a single garden storage shed that does not exceed 50 square feet in area and is less than 10 feet in overall height is exempt from a building permit. Only one exempt shed per property is allowed. Larger sheds and any additional sheds require building permits. All sheds must comply with DC zoning regulations including setback requirements and lot coverage limits. Sheds cannot be placed in required front setbacks. In residential zones (R-1 through R-3), accessory structures must meet rear and side yard setback requirements. Sheds with electrical wiring, plumbing, or mechanical systems require separate trade permits. In historic districts, visible accessory structures may require Historic Preservation Office review. DOB handles permit applications through its online portal. DC's high property density means setback requirements are particularly important for shed placement.
Building without required permit: NOV from DOB, fines $1,000-$4,000. Non-compliant structures may require modification or removal.
