Shed Permits — Complete Guide (2026)
Size thresholds, exemptions, and how to get your storage shed permitted in all 50 states
The most common question about shed permits: “What size shed can I build without a permit?” The short answer is 120 sq ft in most jurisdictions — but many allow up to 200 sq ft, and a few require permits for any permanent structure. The permit threshold is only part of the story. Setbacks, HOA rules, and utilities can require a permit even for a tiny shed.
When you need a shed permit
| Work type | Permit required? | Notes |
|---|---|---|
| Shed over 200 sq ft | Usually yes | Most jurisdictions require permit above 200 sq ft |
| Shed over 120 sq ft | Depends | Some jurisdictions start at 120 sq ft threshold |
| Shed with electrical or plumbing | Always | Trade permits required regardless of shed size |
| Shed on permanent foundation | Usually yes | Concrete slab or footings trigger permit |
| Shed under 120 sq ft, no utilities | Usually not | Still check setbacks and HOA rules |
| Pre-built shed on skids | Depends | Treated as non-permanent in many jurisdictions |
| Shed used as habitable space | Always | Bedroom, office, gym — full building permit required |
How to get a shed permit — step by step
Look up your jurisdiction’s size threshold
The exemption limit is 120 sq ft in some cities, 200 sq ft in others, and some require a permit for any permanent structure. Check your local building department’s website or call before you buy materials.
Check setback requirements
Accessory structures typically need to be 3–10 feet from property lines and in some cases a minimum distance from the main house. Verify for your specific parcel — corner lots often have different rules.
Review HOA rules
If you have an HOA, get written approval before applying for a permit. HOAs often restrict shed placement, height, color, and material regardless of city rules.
Submit permit application with site plan
A basic shed permit requires a plot plan showing the shed location with dimensions and setbacks marked. Include the shed dimensions, height, and foundation type. Many jurisdictions approve these in 1–3 days.
Build and schedule inspection
Post the permit on-site. For sheds with a concrete slab, a footing inspection may be required before pouring. Final inspection once the shed is complete. Shed kits from major retailers often include compliant plans.
