Permit exemption rules for sheds — what you need to know
Most states have a threshold below which shed construction does not require a building permit. This threshold is commonly 120–200 square feet, but it varies by state and often by municipality within a state. Check both your state rules and your local city or county rules — the local rules often apply and may be stricter.
Setback requirements still apply — even for exempt sheds
Even if your shed is below the permit threshold, setback requirements from property lines, easements, and other structures still apply. Setbacks are commonly 5–10 feet from property lines for accessory structures, but can be as small as 1–3 feet in dense urban areas and as large as 20 feet in some rural zoning districts.
HOA rules can be stricter than local code
If your property is in an HOA, the HOA may have rules about shed appearance, location, size, and material that are stricter than local building code. HOA violations can result in fines and required removal. Check your CC&Rs before purchasing or building.
When a permit is actually helpful
For larger or more expensive sheds — particularly workshops, studios, or structures with electrical — getting a permit documents the work, ensures it meets code, and prevents issues when you sell the property. An unpermitted shed that is clearly visible on satellite imagery can complicate real estate transactions.
