Alan’s Metal Building Buyer's Guide

In the previous chapter, you explored essential building regulations, zoning requirements, and setback rules from your local planning office. Now that you have that information, it’s time to create a site plan. Grab a tape measure and head to your chosen location to ensure a smooth installation.

The foundation for your metal building must be completely level, though this doesn’t mean flat—it just ensures there’s no slope.

Look for an area that is already mostly level, or one that can be adjusted. Your building will also need at least three feet of stable ground around it to allow installers to set up their ladders safely. If you’re purchasing a large metal structure, like a commercial unit, forklift access during installation may require six to eight feet or more of clearance on all sides.

Local codes may mandate grading around your building to ensure proper drainage. This often means the site where your building will sit needs to be raised about six inches higher than the surrounding ground, extending at least 10 feet out. Before finalizing your site, check your notes from discussions with your local building department to confirm any grading requirements.

A gentle slope ensures that water drains away from the metal building, protecting the foundation from potential damage. If the ground isn’t perfectly level, a concrete contractor can usually handle the necessary grading. However, excavation and leveling will add to your costs, so selecting a spot that is already relatively even is the most cost-effective option.

Before installing your metal building, inspect the area for overhead utility lines, as they could pose a safety hazard. Choose a location that’s free of overhead lines within 20 feet of the structure. If power lines are nearby and you’re unsure about placement, reach out so we can discuss the best approach.

The highest point of a typical metal building is usually three to four feet above its legs. If there are trees nearby with branches extending over the site, trimming them in advance will help ensure there’s enough clearance for proper installation.

Use stakes, sticks, or flags to outline the four corners of your metal building.

If your chosen site is near property lines, structures, wells, or septic fields, measure the distance from each and confirm that the building will be positioned at a safe distance from all obstacles and boundaries.

Pay close attention to setbacks from property lines. Fences don’t always align exactly with property lines, so you may need to leave extra space. If your metal building will be close to a road, verify where your property line actually begins. The public right-of-way is often wider than the road itself, meaning your property boundary might be set back 10 feet or more. Your local planning department can provide precise measurements.

If your property has easements, building over them is typically not allowed. Planning to grade or excavate? Before breaking ground, it’s crucial to check for underground utilities. Call 811 or visit call811.com anywhere in the U.S. to request a site marking.

If underground utilities are present near your site, you may need to consider relocating your metal building or consulting a concrete contractor for possible solutions.
