Container placement and permits

Choosing the spot

• Doors first. Decide which way the doors face before delivery day. You need room to swing them fully open, and you want them facing your working area rather than a fence line.
• Drainage. Do not sit a container in the lowest spot on the site. Standing water rots the underside faster than anything else.
• Airflow. A small gap around the unit lets the shell dry after rain and reduces condensation inside.
• Access for later. If you may move or resell the unit, keep the truck route clear rather than building around it.

Foundations

A container carries its weight through the four corner castings, so it does not need a full slab. Level pads under those four corners are enough for most sites: concrete pads, paving slabs bedded properly, or treated timber sleepers. Get them level with each other, because twist in the frame is what makes doors stop closing.

Wind and tie-down

An empty container is light for its size and presents a large flat side to the wind. In exposed or coastal locations, and anywhere with high wind loads, an empty unit should be anchored, ballasted or tied down. Anchoring requirements depend on your location and ground, so treat this as a question for a local engineer rather than a fixed rule.

Permits and permissions

Rules vary widely by state, county, city and zoning district, and they change. We cannot tell you what applies at your address, and you should not rely on any seller who claims to. What we can do is tell you the right questions to ask your local planning or building department before you order:

• Is a shipping container allowed as accessory storage in my zoning district?
• Is there a size, height, quantity or setback limit from boundaries?
• Does it need a permit if it is not fixed to a foundation, and does that change if it is?
• Do rules differ if the container is occupied, has power or plumbing, or is used commercially?
• Are there screening, colour or siting conditions?
• Do I need consent from a landlord, HOA or leaseholder as well?

Get any answer in writing where you can. It costs nothing and it settles disputes later. If you are on a leased or rented site, check the lease as well as the local rules.
