Average Cost of a 30×50 Metal Building With a Slab

A 30×50 metal building gives you 1,500 square feet of usable space, making it a popular size for garages, workshops, equipment storage, hobby shops and small businesses.

But before choosing the size, most customers want to know one thing:

What is the average cost of a 30×50 metal building with a slab?

For planning purposes, a completed 30×50 metal building project with concrete may fall somewhere around $30,000 to $60,000+. However, that is only a general planning range—not a quote.

Your actual cost can change significantly depending on building height, concrete specifications, doors, windows, insulation, site preparation, location and custom features.

At Two Way Buildings in Waycross, GA, we provide customized pricing based on the building you actually want rather than relying on a one-size-fits-all advertised price.

How Big Is a 30×50 Metal Building?

A 30-foot-wide by 50-foot-long building provides:

30 × 50 = 1,500 square feet

That extra length makes a 30×50 especially useful when a 30×30 or 30×40 garage would not leave enough room for storage or work space.

30×50 Metal Building Cost Breakdown

A useful way to plan your budget is to separate the project into different components.

Metal Building

A general planning range for the building and installation could be approximately $18,000 to $35,000+ depending on the specifications.

Features that can change the price include:

• Sidewall height
• Roof style
• Steel specifications
• Garage door sizes
• Number of doors and windows
• Lean-tos and porches
• Insulation
• Location and engineering requirements

Concrete Slab and Site Work

Concrete and site preparation could add approximately $12,000 to $25,000+ depending on the slab design and property.

Factors include:

• Slab thickness
• Footers
• Reinforcement
• Site grading
• Fill material
• Concrete accessibility
• Drainage
• Local concrete and labor prices

Concrete should always be planned around the building specifications. The National Ready Mixed Concrete Association(opens in new tab) provides educational resources concerning ready-mixed concrete.

What Can You Do With a 30×50 Metal Building?

With 1,500 square feet, a 30×50 building offers considerably more flexibility than a small detached garage.

Home Garage

Park multiple vehicles while leaving room for lawn equipment, shelves, tools and storage.

Mechanic or Hobby Shop

Add garage bays while reserving space for toolboxes, workbenches, lifts or equipment.

Boat and Side-by-Side Storage

The extra building length can make it easier to store boats, trailers, ATVs and recreational equipment.

Small Business Shop

A 30×50 can provide storage, work space or equipment protection for contractors and small businesses.

Farm Equipment Storage

With properly sized doors and adequate height, a 30×50 can provide useful covered space for tractors and other equipment.

What Makes a 30×50 Building More Expensive?

Taller Sidewalls

A taller building generally requires additional materials and may affect engineering requirements.

Large Garage Doors

Multiple overhead doors or oversized doors for RVs and equipment can increase the price.

Insulation

If you plan to work in the building year-round or eventually heat and cool it, insulation should be considered during the design phase.

Lean-Tos and Porches

These additions create valuable covered space but also increase the overall building footprint and material requirements.

Difficult Site Conditions

Uneven property, drainage problems, soft soil or limited access can increase site-preparation costs.

Before pouring concrete, read our Georgia metal building site preparation guide.

Does a 30×50 Metal Building Need a Permit?

Requirements vary by jurisdiction and how the building will be used. Before construction begins, check your city or county’s permit, zoning and setback requirements.

You can also review current state construction information through the Georgia Department of Community Affairs(opens in new tab).

30×50 vs. 30×40 Metal Building

A 30×40 building provides 1,200 square feet while a 30×50 provides 1,500 square feet.

That means the 30×50 gives you 300 additional square feet.

If your budget allows, that extra 10 feet can make a major difference when you start adding vehicles, shelves, equipment and a work area.

You can compare pricing with our 30×40 metal building cost guide.
