Shed Permit Guide: What You Need and When

Do You Need a Permit for Your Shed?

Permit requirements for sheds vary significantly by jurisdiction. Here is what to know before you build.

Most Jurisdictions Exempt Small Sheds

Most building departments exempt small accessory structures from permit requirements — the exemption typically applies to sheds under 100 to 200 square feet (common thresholds: 100 sq ft, 120 sq ft, or 144 sq ft depending on the jurisdiction). A shed under the exemption limit can be installed without a permit but must still meet setback requirements. Confirm the specific exemption size for your zoning district with the local building department — the threshold varies by municipality and sometimes by zoning district within the same municipality.

Structures Over the Exemption Size Require a Permit

A shed over the exemption size requires a building permit in most jurisdictions. The permit process includes: plan submittal (a simple site plan showing the shed location, size, and distance from property lines, plus the manufacturer’s drawings for a prefab or construction drawings for a site-built shed), plan review (1 to 4 weeks in most jurisdictions), permit issuance, construction, and a final inspection. Electrical permits are required separately for any electrical installation in the shed. Permit fees: $75 to $600 depending on the jurisdiction and the project value. (For more on this, see Prefab vs. Site-Built Sheds: Which Is Right?.)

Setback Requirements Apply Regardless of Permit

Even a shed below the permit threshold must comply with the local setback requirements for accessory structures — the minimum distance from the property line, from the main structure, and from any easements. Typical accessory structure setbacks: 3 to 10 feet from rear and side property lines. Front yard setbacks are usually more restrictive. HOA rules may impose additional setback requirements beyond the zoning minimum. Confirm setback requirements before siting the shed — a shed placed over the setback line must be relocated at the owner’s expense. Document the shed location with a measurement from the property line to the shed wall before installation. (For more on this, see Questions to Ask Before Buying or Installing a Shed.)

Working With a Contractor on This Project

Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.

Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.

Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.

Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.

Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.

Making a Confident Decision

The information in this article is designed to help you ask better questions of the professionals you work with, evaluate their answers with more confidence, and understand the decisions involved in this type of home services project. It is not a substitute for professional assessment of your specific home.

Every home is different. Roof slopes, local weather, tree exposure, soil conditions, and existing system condition all affect what the right solution is for your specific situation. The general principles here apply broadly, but a professional who assesses your home in person will give you guidance that accounts for the details that general articles cannot.

When you are ready to move forward, getting at least two or three quotes from licensed, insured, local contractors is the most important practical step. It lets you compare approaches, assess contractor quality, and confirm that the solution proposed matches your specific situation and budget.
