Do You Need a Shed Permit? Complete Guide
Most cities exempt small storage sheds from permit requirements — but the size threshold varies significantly. The magic number is usually between 100 and 200 square feet. Sheds with electricity, plumbing, or permanent foundations almost always need a permit regardless of size.

You'll typically need a building permit when:
- Shed exceeds your city's size threshold (typically 100–200 sq ft)
- Shed has electrical wiring or plumbing
- Shed is on a permanent foundation (concrete slab or footings)
- Shed exceeds height limits (usually 10–15 feet)
- Shed will be used as a living space, office, or workshop
When You DON'T Need a Permit
These projects are typically exempt from permit requirements:
- Small storage shed under the local size threshold (100–200 sq ft varies by city)
- Prefabricated shed placed directly on the ground or gravel pad
- Shed with no electrical, plumbing, or permanent foundation
- Temporary or portable storage structures
Exemptions vary by city. Always check your local requirements.
Typical Permit Costs
Permit fees vary by city and project scope. Here are typical ranges:
| Project Scope | Typical Permit Fee |
|---|---|
| Small shed (under 200 sq ft) | $50 – $150 |
| Medium shed (200–400 sq ft) | $100 – $300 |
| Large shed or workshop (400+ sq ft) | $200 – $500+ |
These are permit fees only and don't include construction costs. Most cities calculate fees based on estimated project value.
The Permit Process: Step by Step
- 1 Measure your planned shed size and check your city's permit threshold
- 2 Check zoning setback requirements — sheds often need to be 3–5 feet from property lines
- 3 Determine if your shed needs a foundation (may trigger additional requirements)
- 4 Submit a permit application with a site plan if required
- 5 Build your shed within the approved specifications
- 6 Schedule a final inspection if required by your city
Documents You'll Need
- Completed permit application
- Site plan showing shed location and distances from property lines
- Shed dimensions and height specifications
- Foundation details (if applicable)
- Manufacturer's specifications (for prefab sheds)
Common Mistakes to Avoid
Assuming your shed is exempt without checking — size thresholds range from 100 to 200 sq ft depending on the city
Placing a shed too close to the property line — most cities require 3–5 foot setbacks for accessory structures
Adding electrical to an unpermitted shed — this almost always triggers a permit requirement
Exceeding height limits — many zoning codes limit shed height to 10–15 feet in residential areas
Frequently Asked Questions
The most common threshold is 120–200 square feet, but it varies by city. Some cities exempt sheds up to 200 sq ft, while others require permits for anything over 100 sq ft. Use our free lookup to check your city's specific limit.
Prefab sheds follow the same rules as site-built sheds. If your prefab shed is under the local size threshold and doesn't have electrical or plumbing, it's likely exempt. The permit requirement is based on the structure, not how it was built.
No — sheds must meet zoning setback requirements, which typically require 3–5 feet from side and rear property lines. Front-yard sheds are prohibited in most residential zones. Some cities also limit the total lot coverage of all structures.
Yes — adding electrical wiring to a shed requires an electrical permit in virtually all jurisdictions, even if the shed itself didn't need a building permit. The work typically needs to be done by a licensed electrician.
Converting a shed to a living space or habitable office requires permits and must meet building code for habitable structures, including insulation, egress windows, electrical, and possibly plumbing. This is a much more involved process than a simple storage shed.
