Built-On-Site Sheds vs. Prefab Sheds: Which Should You Choose?
Adding a shed to your property is one of the smartest and most versatile ways to increase your usable space. Whether you're looking for extra storage, a dedicated workshop, recreational space, or a peaceful backyard retreat, a well-built shed can transform your outdoor area into something truly functional.
One of the most common questions we hear from customers is: What’s the difference between a prefab shed and a built-on-site shed? The answer comes down to craftsmanship, customization, and installation quality—three key factors that can make all the difference when buying a shed.
Understanding the pros and cons of each option is essential to making the best decision for your home, your yard, and your long-term goals.
What Is a Prefab Shed?
A prefabricated shed, also known as pre-built and/or prefab sheds are built off-site, usually inside a factory or warehouse, and delivered to your home either fully built or in large prebuilt sections. Once it arrives, it’s either dropped into place or reassembled on your property.
Prefab Sheds Benefits:
- Speedy installation: Once delivered, prefab shed setup can take just a few hours.
- Convenient sizing: Prefab sheds often come in standard sizes that are easy to choose from.
- Simplicity: Prefab sheds work well for basic storage needs with minimal customization.
That said, prefabricated sheds do have their limitations.
- Limited design flexibility: Sizes, layouts, and upgrades are often limited.
- Delivery challenges: If you have a narrow gate, fence, or uneven yard, maneuvering a large prefab unit into place may not be possible.
- Foundation mismatch: Poor leveling can affect structural integrity, and prefab sheds may not be built to local code.
What Is a Built-On-Site Shed?
A built-on-site shed is constructed from the floor to the shingles right in your backyard. Rather than delivering a finished storage shed, our Heartland team brings all the shed materials to your location and builds them on your prepared site.
Built-On-Site Shed Benefits
- Custom fit for your space: Whether your yard is sloped, fenced-in, or has limited access, our crews can build the shed exactly where you want it.
- Greater design flexibility: You can choose your size, style, paint color, and add-ons like shelves, workbenches, and windows.
- Code compliance: On-site construction often makes it easier to meet local building codes or HOA guidelines.
- Level and square: The shed is built to match the slope or foundation you provide, ensuring long-term stability.
Considerations When Choosing a Built-On-Site Shed
- Site Preparation: You’ll need to clear the grass or pour a concrete slab before the build day. We require the build site to be level within 6-in. If beyond 6-in, we offer a Leveling Service upgrade, which will allow us to level the homeowner’s ground up to 12-in.
- Scheduled Installation: While not as fast as prefab, Heartland coordinates with you for a convenient on-site shed installation date, and most sheds are completed the same day
Why Heartland Prefers Built-On-Site Sheds
At Heartland, we specialize in built-on-site sheds because we believe in delivering exceptional craftsmanship and personalized installation tailored to your unique needs and landscape. Prefab sheds may be quicker to drop off, but they often come with drawbacks. Our built-on-site sheds are crafted by installers who ensure every wall is straight, every corner is square, and every detail is done right because we believe your shed should last for decades, not just a few seasons. Another major benefit? Accessibility. With built-on-site installation, you don’t need a crane, oversized gate, or extra-wide driveway. Our team carries the materials in and constructs the shed where it belongs—right in your backyard. Be careful, some of our competitors who build sheds on-site charge extra for carrying materials.
Prefab vs. Built-On-Site: Which Is Right for You?
Here’s a quick comparison to help you decide:
| Feature | Prefab Shed | Built-On-Site Shed |
|---|---|---|
| Installation speed | Faster (a few hours) | One-day build, may take longer for larger-sized sheds |
| Customization | Limited | Unlimited customization potential |
| Yard accessibility | Requires wide/open access | Works with tight backyard spaces such as fences |
| Site-leveling | Must be pre-leveled precisely | Foundation can be leveled by the installer |
| Compliance and codes | May vary | Easier to meet local requirements |
If you’re looking for a simple, fast fix, a prefab shed might meet your needs. But if you care about durability, flexibility, and long-term value, a built-on-site shed is the smarter investment.

Built-On-Site vs. Prefabricated Sheds FAQs
Are permits required for built-on-site sheds?
Shed permit requirements vary by location. Some municipalities require a building permit based on the shed's size or foundation type. We recommend checking with your local zoning office before installation.
Are built-on-site sheds more expensive than prefabricated sheds?
Built-on-site sheds may have higher costs upfront than prefab sheds, but they offer greater value, durability, and customization, making them a better long-term investment.
Can I install a shed myself instead of using a built-on-site service?
If you’re an avid DIY’er, DIY sheds are a great option. Heartland’s built-on-site sheds are installed by trained professionals to ensure the structure is level, secure, and compliant with local standards.
What if my yard has limited access?
No problem—built-on-site sheds are ideal for hard-to-reach areas. Since all materials are brought in piece by piece, you don’t need a wide gate or open driveway.
Are built-on-site sheds permanent structures?
Built-on-site storage sheds are designed to last well past the warranty but are not considered permanent structures like garages or homes. They can often be moved or modified with the right tools and planning.
Can built-on-site sheds be customized?
Yes. With Heartland, you can choose your size, color, door and window placement, roof style, and extra features like shelves, ramps, or lofts.
