Container Home Zoning: Where Shipping Container Homes Are Allowed

A container home used as a house needs the same zoning as any other home, usually residential or agricultural, and the approval is decided by your city or county rather than your state. Zoning rarely bans containers outright; minimum home sizes, design rules and HOA covenants are what usually stand in the way.

What States Allow Shipping Container Homes?

There's no official list, because states rarely decide the question. Zoning is set by cities and counties, and building permits come from the local building department. A container home can be legal in one county and blocked in the next one over in the same state.

Building codes have caught up. Starting with the 2021 edition, the International Building Code has a section for shipping containers repurposed as buildings, Section 3115, and the residential code points container structures to it. In places that have adopted those editions, a building official has a clear path to approve a container design. Where an older code is in force, approval may depend on the official's judgment and your engineer's plans.

Zoning Rules That Trip Up Container Homes

Zoning controls land use, not building materials, so a zone that allows a house usually allows a container house too. The trouble comes from standards in the code that assume a conventional home:

  • A minimum floor area that a single container can't meet
  • Exterior material rules that don't allow exposed metal siding
  • A minimum roof pitch that a flat container roof doesn't meet
  • Design review in historic or planned neighborhoods
  • A minimum home width meant to exclude narrow buildings

Joining several containers, adding a pitched roof or covering the steel with siding can solve most of these. Rural and agricultural zones tend to have fewer appearance rules, which is why many container homes go up outside cities. Our residential zoning guide and agricultural zoning guide explain how those districts differ.

Building Code Requirements for Container Homes

A container home must meet the same building code as any home, with extra steps for the steel box itself. Under Section 3115, each container must carry its original data plate, verified by an approved agency, and the plans must show the dimensions and properties of the steel and floor. Cutting openings for doors and windows weakens the walls, so expect an engineer to design the reinforcement.

Insulation, egress windows, plumbing, electrical and a code-compliant foundation are also required. Wikipedia's article on shipping container architecture notes that permits can be hard to get where officials haven't seen container buildings before, so stamped engineered plans help.

Can I Put a Shipping Container on My Property for Storage?

That's a different question from a container home. A storage container is usually an accessory structure, and many residential codes restrict them, limit them to temporary use during construction or require screening and a permit. Agricultural and industrial zones are usually more lenient. Our outdoor storage zoning guide covers storage uses.

How Difficult Is Local Zoning Approval?

In a zone without appearance rules, approval is often no harder than for a custom home. In a suburb with design review or an HOA, it can be close to impossible. HOA covenants are private rules, and many ban nontraditional building materials no matter what zoning says.

  1. Search for your city's zoning map and confirm the district allows a single-family home.
  2. Read the district's minimum floor area, roof and exterior material rules.
  3. Ask the building department which code edition is adopted and whether they've permitted container homes before.
  4. Review any HOA covenants or deed restrictions.
  5. Hire an engineer familiar with container structures before you buy containers.

For other small or nontraditional homes, compare the rules for a tiny home, a barndominium or a manufactured home.

Container Home Zoning FAQ

Are container homes legal in the US?

Yes, in many places, as long as the home meets local zoning and the adopted building code. The approval is local, so the answer depends on your county or city.

Can a container home be an ADU?

Often, if it meets the code's accessory dwelling unit size, setback and design rules. Our ADU zoning guide covers those rules.

Does a container home need a foundation?

For use as a permanent home, almost always. Building codes require dwellings to be anchored to a foundation designed for local wind, snow and soil conditions, and an engineer usually designs it for a container.

Is a container home cheaper to permit than a regular house?

Usually not. The permit fees are similar, and the engineering and plan review for a container design often cost more than for a standard house plan.
