Factors That Influence the Cost of a Shed Build

The cost of build a shed depends on various factors. Each factor is responsible for influencing the cost of the shed. Here is the breakdown of the factors influencing the cost of a shed build.

Shed Size:

The shed size also influences the cost associated with the shed. The cost will increase with the size of the shed. A small shed with a size of 100 square feet will cost less compared 200 square feet shed. Similarly, a small shed measuring 4×7 feet can cost between $100 and $1,000, while a larger shed measuring 12×16 feet can cost between $3,000 and $14,000.

Shed sizes	Square feet	Typical cost
6×8	48 sq ft	$750 –$1,000
8×8	64 sq ft	$2,000 $1,500
8×10	80 sq ft	$1,200 – $2,500
8×12	96 sq ft	$1,500 – $3,000
10×10	100 sq ft	$800 – $3,500
10×12	120 sq ft	$2,000 – $4,200
10×16	160 sq ft	$2,800 – $5,200

16×24	384 sq ft	$9000-$15,000
2×20	400 sq ft	$12,000-$18000

Material Choice:

The price of a shed is also influenced by the types of materials used in building the shed itself. For instance, a tiny prefabricated vinyl shed may be as low as $180, whereas a metal shed may range anywhere from $400 to $5,000. The price of a wooden shed varies from $3,000 to $15,000, depending on features such as ventilation and size. A shed made up of brick or stone may cost as much as $30,000.

Besides the pricing factor, it is important to choose material based on durability, reliability, and affordability. Wood is a popular choice, but it demands high maintenance against rot and weather damage. Metal sheds are expensive, but they last longer despite low maintenance. They are strong, resist pests, and handle harsh weather well. Vinyl is another option that offers a mix of low maintenance and durability. It’s resistant to weather and pests, but can be expensive.

Foundation Type:

A strong foundation is the most important part of a shed building. The foundation type will also affect cost and stability. Gravel is one of the cheapest options, and it is highly suitable for lightweight sheds.

Concrete is often considered the best option because of its stable nature and high resistance against weather damage. Skids offer another alternative, but they are not as durable and stable as concrete.

Foundation type	Cost per square foot
Gravel pad or base	$1.25-$1.90  sq ft
Floating concrete slab	$4-$8  sq ft
Concrete slab	$5-$25  sq ft
Concrete blocks	$6-$14  sq ft
Screw-pile foundation	$15-$35  sq ft
Skid	$15-$20  sq ft

Roofing and Siding:

Roofing & siding types	Average cost for 12×12 shed
Asphalt Shingles	$140 – $200
EPDM Rubber Roof	$220 – $350
Metal Roof Panels	$250 – $400
Cedar	$350 – $550
Vinyl Siding	$180 – $300
Wood pine siding	$220 – $350
Wood Siding (Cedar)	$400 – $650
Engineered Wood Siding	$250 – $450
Metal Siding	$300 – $500

Labor and Skill:

Labor rates also influence the shed costs. If you opt for the DIY,  you will save on labor costs. However, the method will be time-consuming. On average, it takes about 25 to 50 hours to make a 12×12 shed, depending on your expertise, knowledge, and tools. For a beginner, the project may take longer and involve extra costs for renting or buying tools. On the other hand, hiring a professional can be costly, but it will save you time and resources, thereby leading to significant outcomes. Location also holds significant importance in this matter, as labor rates vary by location.

Permits and Zoning:

Different municipalities have different permit-related rules and construction codes. If you need a permit for your 12×12 shed, you have to pay around $100-$1,000. The cost of living can also differ from one region to the next, which is why the average hourly wage will affect the total price of the shed. In most cases, a contractor’s hourly rate will fall between $50 and $100 per worker. Fees also differ by location. In general, you can expect to pay $50–$250 for a basic shed permit and up to $500 if site inspections are the need of the hour.

DIY vs. Professional Shed Construction

While planning a 12×12 shed, one of the first choices you will face is whether to build it yourself or hire a professional.

DIY Build

A 12×12 shed typically costs $2,600 to $3,500 in materials, depending on what you choose for walls, roofing, and other items. The right tools are needed.  If you don’t already own essentials like a drill, saw, or level, you will have to buy or rent them. Renting tools increases the overall cost. Buying tools is expensive at first, but helpful for future projects. Even the small supplies like nails, screws, brackets, and adhesives can cost more than the total cost.

Depending on your skill level, it takes about 20 to 50 hours to build a 12×12 shed. Beginners may encounter challenges that slow the building process or require extra materials to fix mistakes. While DIY offers both saving and satisfaction, it also requires patience, careful planning, and basic construction skills.

Building a 12×12 shed yourself can save money, but it comes with material, tools, and time expenses. You need to buy or rent tools, and small items like screws and brackets can increase the total cost. Beginners often face challenges that may cause slow progress or require extra materials to fix mistakes.

Professional Build

Depending on design and materials, hiring a professional for a 12×12 shed will cost more because of labour, with the total costs ranging from $2,000 to $25,000

The main benefit is time savings; experts can finish the shed quickly and ensure everything is built correctly. You can also get advantages like faster results, better quality, and a warranty.

The disadvantage can be a high price and fewer customization options than the building itself.

Hiring a professional is very beneficial as it comes with saving time since the shed is built without you needing to do any work. You will also get strong, accurate construction because professionals have the right tools and know how to fix problems. Many contractors even offer a warranty for extra security. However, the drawbacks are that it costs more because of labour, and you can not customize anything until you pay extra.

If you decide to hire a contractor for better quality and time savings, understanding how to effectively bid on construction projects is crucial for securing the best value.

Is It Cheaper to Buy or Build a Shed?

The cost depends on the shed’s size, the materials you choose, and the time you want to spend. Both buying and building have their own advantages and disadvantages. Here are the following.

Buying a Shed

Buying a premade shed is fast and easy. A 12×12 shed usually costs about $2,500–$7,000 or more, depending on the design.

Advantages of buying a shed:

• Saves time! You don’t have to spend weeks planning, constructing, and measuring.
• Buying the materials for DIYs separately can end up costing more.
• No need for tools or any building experience
• Construction is built professionally, ensuring long-lasting strength and accuracy.
• Easy upgrades are that you can personalize the shed without the trial and error of DIY.

Disadvantages of buying a shed:

• 20–50 hours of work require time, patience, and careful planning
• By increasing overall costs, you may need to buy or rent tools
• Extra material costs can lead to DIY mistakes.
• Construction skills are required, making it challenging for beginners.
• The downside is that the overall price can be increased by custom changes.

Which option is cheaper?

If you have time, building a shed yourself is a cheaper option.

If you want speed, convenience, and professional accuracy, then buying is better.

Build Quality Tiers: Basic, Mid-Range, and Premium

The cost to build a 12×12 shed also depends on quality tiers. The quality consists of several axes, including reliability, durability, performance, conformance, and perceived quality.

Basic Tier

The basic tier provides the minimal acceptable functionality, even at the lowest possible price. The materials used in the basic tier are of low quality, but they are good enough for simple uses. They are not designed for heavy use, thereby possessing poor longevity.

Mid-range Tier

Mid-range shows a balance between quality and cost. The tier offers superior quality materials, workmanship, and reliability compared to the basic tier. It often represents the ease for everyday users with better reliability, durability, aesthetics, features, and performance.

Premium-Tier

Premium-tier consists of high-quality products characterized by superior materials, craftsmanship, and durability, and often provides the best user experience or design as part of the tier. They are for users who demand the best performance, longevity, durability, and top-class performance.

Permits and Local Regulations

It is important to check your local permit rules before building a 12×12 shed. Larger sheds or those with electricity or plumbing require a building permit in many areas. You should also follow the rules for where the shed will be placed on your property. Ignoring such rules can lead to fines or delays. So, always check with your local building department before starting any project.

Cost-Saving Tips for Building a Shed

• Build your shed using common lumber sizes so you do not have to waste money and wood.
• The list of all the materials and requirements should be made before buying. This stops by making mistakes and costs.
• Shed kits should be used as they are precut and can save time, effort, and money.
• The worker will charge less, so you should build the shed in the off-season.
• Use standardised wood to avoid cutting mistakes and wasting material.
• Use old doors and leftover hardware from other projects to save the cost.
• A square-shaped basic shed with a simple roof is cheaper and easier to build.
