Questions to Ask Before Buying or Installing a Shed

What Should You Ask Before Buying or Installing a Shed?

Ask the building department (not the retailer) about permits and setbacks, get a foundation recommendation for your site, confirm delivery access, and read the warranty terms before you buy. Confirm whether installation is included too. Getting this wrong is expensive to undo: a 12×16-foot shed weighs 1,500 to 3,000 pounds and cannot be repositioned by hand once it is set.

What Permits Are Required?

Ask the local building department (not the shed retailer): “What is the permit exemption size for accessory structures in my zoning district, and what setbacks apply?” The retailer typically does not know the specific permit requirements for your location. Setback requirements determine where on the lot the shed can be located — a shed placed too close to the property line must be relocated at the owner’s expense. (For more on this, see Shed Permit Guide: What You Need and When.)

What Foundation Do You Recommend?

Ask the installer: “What foundation do you recommend for the intended use (storage vs. workshop) and the specific site conditions?” The answer should reflect both the use (a workshop needs a concrete slab) and the site (a sloped site may need grading; a high water table site may need an elevated foundation). An installer who recommends the same foundation for every shed regardless of use or site is not providing a site-specific assessment. (For more on this, see Shed Foundation Options: Gravel, Concrete, and Piers.)

What Is the Delivery Situation?

Before purchase: confirm that a delivery vehicle can access the installation site (gate width for a fence, overhead clearance for trees or utility lines, the distance the shed must be moved from the delivery vehicle to the final location). A 12×16-foot shed weighs 1,500 to 3,000 pounds — it cannot be easily repositioned manually. A delivery access problem discovered on delivery day can result in the shed being placed in a non-ideal location. (For more on this, see Hidden Costs of Shed Installation.)

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.
