Average Cost to Build a 12×12 Shed

The average cost of a 12×12 shed depends on the type of shed that you want to construct. Here are different types of sheds that are generally constructed for any residential or commercial project.

Apart from the shed type, the average cost to construct a 12×12 shed depends on the construction method. For instance, DIY built, contractor-built, and custom contractor-built have different average costs. In the table below, there are different types of construction methods for a shed with an average cost.

• DIY or Prefab Kit: The storage sheds that are constructed with a DIY or Prefab kit are the low-end projects.
• Contractor-Built: A professional contractor builds a mid-range shed of 12×12 size.
• Custom Contractor-Built: If you want a luxury 12×12 storage shed, then you can provide your custom shed design to the contractor.

Whether you want to construct a 12×12 shed yourself or a custom contractor-built one, you must get residential estimating services.

Cost Per Square Foot for a 12×12 Shed

Estimating the construction cost of a 12×12 shed is impossible without calculating the shed cost per square foot. But the million-dollar question is how many square feet are in a 12×12 shed. There are 144 square feet in a 12×12 floor space. However, the cost per sq ft for a shed varies with materials, design, labour rates, and shed type.

Have a look at the table to know the shed square footage cost for different categories.

If you want to calculate the cost per square foot, you can follow the method that contractors usually use to estimate the cost. They calculate the total construction footprints and divide the combined cost of the material, labor, overhead, and profit margin by that area.

Understand this by a simple example:

Cost Per Square foot = Combined Cost / Total footage area

= $1000+$500+$1400+$600 / 144

=$3500 / 144

Cost Per Square foot = $24.3

If you have any doubts about your calculation, you can avail building cost estimating services from professionals and ensure that you get the right numbers for your construction projects.

Material Cost Breakdown for a 12×12 Shed

Quantity takeoff is the critical first step of any construction project. If any material is missing during the takeoff assessment, the entire project budget can be disrupted, and the project may also overrun in time during completion. Therefore, the material takeoff and cost breakdown of the required materials are essential when constructing a 12×12 shed.

You can hire seasoned quantity takeoff service providers to ensure that no material is missed during the takeoff assessment and get the exact cost for the materials.

Here is a complete shed material cost breakdown of material cost with concrete foundation and lumber framing.

However, the price of materials varies depending on various factors, including:

• Market inflation
• High demand for the material
• Unpredictable productivity
• Global outreach
• Increasing labor rates
• Shortage of raw material

Foundation Costs for a Shed

Most shed construction projects failed because of inaccurate foundation cost estimation or neglecting the foundation cost altogether. Foundation cost is the building block of estimating the cost to build a 12×12 shed. However, for constructing a storage shed, there are different foundation options available.

Look at the most common foundation types corresponding to their cost per square foot.

You must select the right foundation for your 12×12 shed by considering your requirements, foundation properties, and your budget. We are going to mention each type of foundation in detail, which will help you to choose the suitable one.

• Floating Concrete Slab Foundation: It is also known as the load distributor because it is evenly spread on the ground without concentrating the entire weight on a particular column. The floating concrete slab is the most affordable foundation option for a 12×12 shed because it doesn’t need any deep floating. Additionally, this base is a natural pest barrier and adaptable to soil.
• Skid Foundation: Skid is a pressure-treated steel that is more reliable than the floating concrete slab because it distributes the weight over a large surface area. It is easy to install and is unaffected by climate change.
• Pier Foundation: This type of foundation is suitable for uneven terrain, sloped surfaces, and flood-prone areas. It consists of structural columns that transfer loads directly to the soil. Generally, this type of foundation lies 5 to 6 feet above the soil, which provides a strong load-bearing mechanism.
• Gravel Pad Foundation: It is a highly permeable foundation that is generally used for medium-sized structures, such as a backyard shed. Also, gravel pads are excellent thermal and moisture barriers that make them a popular foundation choice.
• Concrete Block Foundation: This foundation is made of Concrete Masonry Units (CMUs). It is considered a moderate, affordable, and robust foundation option for a 12×12 shed. Like other foundations, it is also pest-resistant.

Note: If you want to install this foundation in your 12×12 shed, you can get suggestions for experts in concrete estimating services, who will guide you in choosing the most suitable concrete block foundation within your budget.

• Screw-pile Foundation: A screw-pile foundation is a combination of steel shafts and helical plates that are screwed deeply into the soil before the foundation installation. It has a high load-bearing capacity and can bear wind forces easily.

What is the Labor Cost to Build a 12×12 Shed?

Labor cost also plays a key role in estimating the accurate cost of a construction project. According to a report, labor cost makes up to 25% to 40% in the total cost of a building project. So, in case of any miscalculation of the labor rates, the entire construction job can be disturbed. Therefore, it is good to hire a dedicated cost estimator who can give you the exact quote for labor costs.

The labor cost to build a 12×12 shed is typically between $500 – $ 2000. This is the total average cost of hiring professionals for each labor task.

Constructing a Shed By Yourself

Key Considerations for DIY

• No matter whether you are building a 12×12 shed by yourself or hiring a professional, a permit is always required. A contractor knows all the obligations to acquire the permit, but you must be careful and fully informed if you are constructing yourself.
• It is important to confirm zoning rules before buying materials so that you do not incur any fines.
• Make a holistic list of all the materials that you need to construct a shed before taking any first step.
• Make sure that you have the basic tools, such as a measuring tape, a circular saw, a drill, and other safety equipment.
• A DIY shed usually takes 3-4 weeks, so if you want to complete it earlier, consider hiring one or more helpers.
• Break the entire project into stages, like foundation, framing, roofing, and insulation, so that you can complete it on time.

Hiring a Contractor

Key Considerations for Hiring a Contractor

• Before hiring a professional contractor, make sure that he holds all the necessary permits and NOCs, so your construction project will not face any delay.
• Request the expert to show the workers’ compensation insurance to protect yourself from liability in case of any on-site mishap.
• Consider a person who is well aware of the climate and the particular terrain in your area.
• Always ask for 2 to 3 references so you can ensure the credibility, timeliness, and workmanship of the contractor.
• Ask for a detailed and transparent bid, including the combined costs of labor, material costs, and all permits. You can also approach a construction estimation consultant to get an 100% accurate bid for your project. timeline, scope, budget, and other specifications.

Key Factors That Affect 12×12 Shed Costs

Various factors influence the cost to build a 12×12 shed. It is important to know each of these factors so you can avoid time runs, budget overlays, and ensure successful project completion. Here, we are going to give the details about each of these factors.

1. Material Choice

The cost of building a 12×12 shed is significantly influenced by the choice of material. For example, if you want to construct your shed with vinyl plank flooring, it costs you almost $2200- $3700. On the other hand, to construct a metal shed, you need $3800-$5800.

Note: Apart from the material pricing, it is essential to consider the durability and reliability of the material.

2. Site Conditions

The site condition is another important factor that affects the cost of building a shed. It is a matter of fact that a sloped surface or soft soil requires extensive groundwork and levelling, which increases the overall cost of your construction project. Also, if your construction site is in a remote location, then you need additional expenses for transportation and labor premium. Therefore, it is important to choose the site that requires minimal groundwork and transportation expenses.

3. Shed Design

The average cost to construct a 12×12 shed also depends on its design and style. For instance, the cost of a simple wooden shed in the garden is between $1000 – $1500, while constructing a steel storage shed requires a budget between $3500 – $5000. Similarly, a two-tier shed made of concrete requires a higher upfront cost. Thus, you can avail cost estimating services before making a budget for constructing your customised shed design.

4. Electrical Installation

It is important to consider the additional cost if you are planning to add electrical installation to your 12×12 shed because this leads to a higher overall project cost. For example, if you want to install lighting in your storage space, you need to install an electric outlet, proper interior wiring, a bulb, and the main power board. This small addition can cost you up to $100 – $2500.

5. Other Customisation Features

If you want to construct a premium 12×12 shed, then you must keep in mind the extra burden on your budget. For instance, motorised shutters, personnel windows, or heavy automatic sliding doors require powerful tracking systems that are expensive. Moreover, incorporating plumbing and advanced ventilation systems eats a significant chunk of the budget.

Permit Costs and Local Regulations

Different municipalities require different permits because all these have varying construction codes. It is important to get these permits for the successful completion of the construction project. In case you need a permit for building your 12×12 shed, you have to spend $500 – $ 1500 to get this.

In the table below, we provide a complete cost breakdown of a 12×12 shed permit.
