Do I need a permit to build a shed on my property?
When a Shed Permit Is Required
Most building departments require a permit for sheds that exceed a certain size, typically 100 to 200 square feet, or that are taller than 10 feet. Sheds attached to a house or placed on a permanent foundation almost always need a permit. If the shed has electricity, plumbing, or heating, permits for those systems are also required.
Even if a shed is small, some jurisdictions require a permit if it's in a front yard, close to a property line, or in a flood zone or historic district. Zoning rules may also limit the number and size of sheds on a property.
Why Permits and Zoning Matter
Permits ensure sheds are built safely and don't violate setback requirements, which dictate how close a structure can be to property lines. They also help prevent drainage issues and ensure the shed doesn't encroach on easements.
Without a permit, you could be forced to move or demolish the shed, and you may face fines. Unpermitted sheds can also complicate home sales and insurance claims.
How to Determine If You Need a Permit
Check your local building department's website or call them. Ask about size thresholds, height limits, and setback requirements. You'll likely need to submit a site plan showing the shed's location and dimensions.
If a permit is required, fees are usually modest—often $50 to $200. Inspections may include footing, framing, and final. If you buy a prefab shed, the manufacturer may provide plans, but you're still responsible for permits.
- Measure your shed's footprint and height.
- Check setback rules from property lines.
- Ask about electrical or plumbing permits if needed.
- Submit a site plan with your application.
- Get final inspection before using the shed.
Common mistakes
- Assuming any shed under 200 square feet is exempt—thresholds vary widely by location.
- Placing a shed too close to a property line without checking setback rules.
- Forgetting that adding electricity to a shed requires an electrical permit.
