Shed build permits, foundations and access guide

Permits, Foundations and Access: What to Settle Before You Order a Shed

16 September 2026

Most shed problems are not build quality problems. They are planning problems, and almost all of them surface after the money has changed hands.

This guide covers the things worth settling first. None are difficult, but each can stall a delivery or force a redesign if left until the truck is booked.

Key Takeaways

Check zoning and permit rules before choosing a size, because they often change at a specific square footage.
Setback rules from property lines and easements are separate from permits, and catch people just as often.
The foundation is not an afterthought, and getting it wrong shortens the life of the building.
A prefab shed arrives fully built, so delivery access is a hard constraint rather than a detail.
Buy for the space you will need in five years, since upsizing now costs less than replacing later.

Start with the permit question

Permit rules are local and vary more than people expect. Many jurisdictions exempt small accessory structures below a certain square footage, and that threshold is exactly where the decision gets made.

Call your township or county before settling on a size. A building just above the exemption can trigger a permit process, plan submissions, and an inspection, while one slightly smaller may need nothing at all.

Setbacks are a separate question and trip up just as many projects. Minimum distances from property lines, septic fields, and easements apply whether or not a permit is required, and an HOA may add rules on top.

Size it for five years from now

The most common regret is buying too small. Storage expands to fill whatever space exists, and the gap between an eight-foot and a ten-foot width costs far less than replacing the building later.

Walk through what will actually live in there. Mowers and wheelbarrows need turning room rather than just footprint, and weekly-use items need to be reachable without moving three other things first.

Think about the door too. A wide opening matters more than total square footage if you are storing a ride-on mower or a trailer.

The foundation decides how long it lasts

A shed on uneven or poorly drained ground will fail from the floor up regardless of build quality. Water is the enemy, and a foundation that keeps the structure level and off wet soil does most of the work.

Gravel pads are the common choice because they drain and they are forgiving to install. Concrete makes sense for heavier buildings, garages, and anything you plan to run power to, while blocks suit smaller structures on stable ground.

Whichever you choose, it needs to be level and ready before delivery day. A building set on an unprepared site will rack, and the doors will stop closing properly within a season.

Delivery access is a hard constraint

This is the one that derails orders. A prefab building arrives assembled on a truck or trailer, so it has to physically reach the spot where it will sit.

Measure the narrowest point on the route, not the widest. Gate openings, low branches, overhead wires, soft lawn, and tight turns between houses all count, and any one can stop a delivery on the day.

If access is genuinely impossible, a kit is the alternative. Kits arrive as components and get assembled on site, which trades convenience for the ability to reach places a finished building cannot.

Prefab, kit or site-built

Prefab is the fastest route and usually the most consistent, because the building goes together in a shop rather than in your yard in whatever weather turns up. You choose a style, pick options, and it arrives finished.

A kit costs less and solves the access problem, but you are supplying the labor and the finish depends on your own work. Site-built makes sense mainly when the design is unusual enough that no standard model fits.

For most homeowners, the decision comes down to access and appetite for assembly. If the truck can reach the spot, prefab is the simpler path.

Style affects usable space, not just looks

Roofline is not purely aesthetic. A barn-style roof creates genuine loft storage overhead, a workshop profile gives you more headroom along the walls, and a saltbox trades some interior volume for a look that suits certain houses better.

Match the roofline to the house as well as the use. A building that clashes reads as an outbuilding forever, while one echoing the home’s roof pitch and siding looks like it belongs.

What to check about the builder

Warranty length is the quickest signal, because a company that stands behind its buildings for years is making a statement about how they are made.

Look for a written warranty on the structure rather than a vague satisfaction promise.

Beyond that, check how long they have been building and whether they will tell you where your building comes from.

Sheds Unlimited has been building since 1988, with Lancaster County roots in Pennsylvania, offers a five year limited warranty across its structures, and publishes a 3D design tool so you can see the configuration before ordering.

Ask about foundations and permitting support as well. A builder who handles those conversations routinely will spot the problem in your plan before you do.

Conclusion

Do the unglamorous work first. Confirm the permit position, check your setbacks, plan the foundation, and walk the delivery route with a tape measure before falling for a particular building.

Once those four are settled, the fun part carries no risk. You are choosing size, style, and color rather than discovering constraints, and the building that arrives is the one you planned for.

Frequently Asked Questions

Do I need a permit for a backyard shed?

It depends entirely on your local jurisdiction, and many areas exempt structures below a certain square footage. Contact your township or county before choosing a size, since the threshold often sits right where buyers are deciding.

What is the best foundation for a shed?

A gravel pad suits most standard sheds because it drains well and is straightforward to prepare. Concrete is the better choice for garages, heavier buildings, and anything that will have power run to it.

How much access does a prefab shed delivery need?

More than most people assume, since the building arrives fully assembled. Measure the narrowest point along the whole route, including gates, overhead branches, and turns between buildings.

What if my yard cannot fit a delivery truck?

A kit is the usual solution, because the components are carried in and assembled on site. You trade the convenience of a finished building for access to spots a truck cannot reach.

What size shed should I buy?

Buy larger than your current list of items suggests. Storage fills available space, and the price difference between sizes is almost always smaller than the cost of replacing an undersized building.

Does the roof style change how much I can store?

Yes. A barn-style roof adds usable loft space overhead, while a workshop profile gives you more headroom along the walls for shelving and bench work.
