Alabama writes its building code at the state level and hands placement rules to whoever happens to have authority over your particular parcel. Sometimes that is a city. Sometimes it is a county. Sometimes it is nobody at all.
Shipping container permits in Alabama are not one approval. They are two separate questions, answered by two different bodies, and the people who run into trouble almost always answered one of them and assumed the other took care of itself.
The first question is a building code question: does this thing need a building permit and an inspection? Alabama sets a residential code at the state level but leaves the actual permitting and inspecting to local jurisdictions. Under Act 2024-443, adopted in 2024, the authority to adopt the statewide residential code moved to the Home Builders Licensure Board, which now maintains an Alabama Residential Building Code Division and an advisory council. The statute is explicit that enforcement is local: the Alabama Residential Building Code "shall be enforced by local jurisdictions that have permitting and inspection programs for residential construction and improvements." A local building code adopted by a county or municipality after January 1, 2027 has to meet the minimum standards of that statewide code (HB198, enrolled, 2024 Regular Session).
That structure has a practical consequence worth naming. If your address sits inside a jurisdiction with a permitting office, that office tells you which code edition applies. If it does not, there may be no one issuing permits at all. The Home Builders Licensure Board itself works from this reality: where a jurisdiction has adopted a local building code, the Board applies that local code, and where none has been adopted, it applies the 2015 International Residential Code as the reference standard for its own investigations (Home Builders Licensure Board).
The second question is a zoning question: is a container an allowed thing to put on this lot, in this district, in this position? Alabama answers this locally too, and the answer is often narrower than people expect. Municipalities may zone land inside their corporate limits. They generally may not zone land outside them. The Alabama League of Municipalities puts it plainly:
"Alabama municipalities have the authority to zone all territory located within the corporate limits of the municipality. No general statutory authority allows municipalities to zone territory in the police jurisdiction." (Zoning in Alabama, citing Roberson v. Montgomery, 233 So.2d 69 (1970))
Counties do not get zoning power automatically either. Alabama counties have no general grant of authority, so a county that wants to zone has to go to the Legislature and get it (Encyclopedia of Alabama, Home Rule). One statewide provision sits in the code: in counties of 600,000 or more people by decennial census, the county planning and zoning commission is invested with the planning authority over the five mile band outside a city's corporate limits, unless the municipality in question is actively exercising zoning jurisdiction and control within that area (Ala. Code § 11-52-30).
Put those together and the honest short answer to "do I need a permit for a shipping container in Alabama" is: it depends less on the container than on the line on the map your property sits inside. In a city, expect a specific rule and a specific size limit. In unincorporated Alabama, there may be no zoning to satisfy and a building department that only wants to hear from you if you are building a dwelling.
The numbers that decide it. A standard 20ft container has a 160 square foot footprint (8ft by 20ft) and stands about 8ft 6in tall. A 40ft container is 320 square feet. Alabama's three largest cities have each written a size cap into their container rules, and those caps land at 150, 160 and 400 square feet. Two of the three are close enough to a 20ft box that the arithmetic decides the outcome.
Birmingham's zoning ordinance does address containers, though not under that name. Title 1, Chapter 4, Article IV covers uses permitted as accessory, and Section 2, item G is headed "Temporary Storage." It permits a temporary storage container in the D-1 through D-5 dwelling districts, plus the UN, MU-L, MU-M, MXD and AG districts, subject to conditions:
Read that fourth condition against the equipment. A 20ft container is 160 square feet. It is ten square feet over Birmingham's temporary storage container cap before you consider anything else, and a 40ft is more than double it. Birmingham's provision is written around the size of a moving pod, not the size of an intermodal box (City of Birmingham Zoning Ordinance).
That does not end the conversation, it relocates it. A container intended to stay is not a temporary storage container at all, it is an accessory building, and Birmingham judges accessory buildings under Title 1, Chapter 3, Section 6. Accessory buildings and structures may be built in a required rear yard, but they may not occupy more than 30 percent of the required rear yard and may not sit nearer than three feet to any side or rear lot line in dwelling districts. Those floor area controls do not apply on lots where agricultural activities and livestock are permitted.
Outside the city line, do not assume you have crossed into unregulated ground. Jefferson County sits above the 600,000 population threshold that § 11-52-30 uses, and metro Birmingham is a dense patchwork of smaller municipalities besides, so the parcel next to yours may answer to a different authority than yours does. Ask Jefferson County Land Development whether your parcel is zoned before you plan around the answer either way. Our Birmingham container delivery page covers site access and placement across the metro.
Mobile is the most explicit of the three cities, because its Unified Development Code names the equipment by brand and by type. Adopted in 2022, the UDC defines a Temporary Portable Storage Unit as a transportable, standardized, reusable container designed for shipping or moving freight, capable of being mounted or moved on a truck, and located on a site for temporary storage. The definition then gives examples: "Pack-Rat", "PODS", or shipping container ("CONEX") (Mobile UDC, Article 8 Definitions).
Article 4 then sets the rules. On a residential site, when the unit is not tied to construction with an active building permit, Mobile allows a temporary portable storage unit subject to these limits:
On commercial and mixed use sites the shape changes: the unit goes on a paved area behind a building, out of required parking, meeting setbacks, again not as a permanent accessory structure, and not on site for more than 180 days with one possible 180 day extension for good cause.
Mobile also carries general conditions that apply either way. No mechanical, plumbing or electrical connections may be made to the unit. It may not be used for flammable or hazardous substances, live animals, or human habitation. It may not be stacked on top of another structure. And units placed during a declared emergency are exempt from the subsection entirely, which matters on the coast (Mobile UDC, Article 4 Use Regulations).
The lesson in Mobile's drafting is the one worth carrying to any Alabama city. The size cap is generous enough for a 40ft box at 320 square feet. The duration cap is what actually governs. Sixty days a year in two stints is a moving allowance, not a storage solution, and the sentence saying it "shall not be used as a permanent accessory structure" tells you the city has already thought about the workaround.
Across the bay, unincorporated Baldwin County works differently again. Its unincorporated area is divided into planning districts under a local act of the Legislature, and county zoning applies in a district only where the voters of that district have adopted it by referendum. Two neighbors a mile apart can therefore sit under genuinely different regimes. Confirm your district's status with Baldwin County Planning and Zoning before you assume either way. Our Mobile container delivery page has depot and access detail for the coast.
Huntsville names shipping containers directly in its definitions, and the definition is the whole story. Article 3 of the zoning ordinance defines a Portable Storage Structure as a transportable storage structure designed and used primarily for storage of household goods, personal items and other materials for use on a limited basis on residential property, then adds:
"For the purposes of this ordinance, the trailer portion of a tractor trailer, boxcars and shipping containers shall also be considered portable storage structures when expressly used for the purposes of on-site storage in residential districts."
Having pulled containers into that category, Section 73.1.2(3) sets the terms. One portable storage structure may be placed on a residential lot without an active building permit, and:
Note the precision of that size cap. A 20ft container is exactly 160 square feet, and its 8ft 6in height clears the 10 foot limit. A standard 20ft box fits Huntsville's rule to the inch. A 40ft box does not fit at all. Huntsville also allows temporary structures including portable storage structures incidental to construction with an active building permit, to be removed when the work finishes, which is the separate and more generous path (City of Huntsville Zoning Ordinance).
One more Huntsville provision belongs in any container conversation, because it applies to the finished look rather than the storage question. Huntsville repeats the same condition on uses in every one of its residence districts, and in its neighborhood business, residential office and office districts as well: no primary or accessory non-residential building or structure with a footprint over 1,000 square feet may use aluminum, steel or other metal siding or cladding as an exterior finish, except by special exception. A single container is well under that footprint. A multi-container building is not.

Alabama has 67 counties and hundreds of incorporated municipalities, and outside the cities the regulatory picture thins out fast. Four patterns repeat often enough to be worth naming.
All three of Alabama's largest cities regulate containers through a temporary use provision rather than a permanent one, and all three cap the clock. Birmingham says 90 days. Mobile says 60 days a year across two occasions. Huntsville says three 30 day permits in twelve months. None of them offers a residential permit for a container that simply lives on the property.
Temporary, in Alabama practice, means the container supports a defined activity with an end date: a move, a renovation, a repair after storm damage, or a jobsite with a live building permit. Every one of the three cities treats an active construction permit as the wider door, and Mobile and Huntsville both allow construction related units for the duration of the work rather than by the calendar.
Permanent means the container stays, which changes its legal category from temporary use to accessory structure. That is where setbacks, rear yard coverage, height limits, screening and exterior material rules start to apply, and where the answer varies most between jurisdictions. If you intend permanence, say so at the zoning counter on the first call rather than discovering the distinction later.
One call to whoever has authority over your parcel settles nearly all of this. The trick in Alabama is working out who that is before you dial. Ask these, in this order:
Write down the name of the person who answered. If the answer later turns out to be wrong, that name is worth having.
We sell and deliver containers across Alabama. We are not your permit office, we do not file applications for you, and we do not interpret your ordinance. What we can do is give you accurate specifications so the conversation with your zoning office is a short one: exact external dimensions, footprint, height, weight, door swing, and the delivery footprint the truck needs. When a city rule turns on whether your box is 160 square feet or 320, precise numbers end the call quickly.
Alabama delivered pricing, starting at $2,279 for a 20ft wind and water tight container delivered in Mobile, was captured from Container One on 6 August 2026. One thing the table below explains at a glance: every Alabama city in our network is served from a depot in a neighboring state, so distance to the depot, not distance to the coast, is what moves the number.
| City | 20ft WWT | 40ft WWT | 40ft High Cube WWT | Serving depot |
|---|---|---|---|---|
| Birmingham | $2,836 | $3,086 | $3,101 | Atlanta GA, 147 mi |
| Mobile | $2,279 | $2,862 | $2,889 | New Orleans LA, 149 mi |
| Huntsville | $2,669 | $2,993 | $2,967 | Tennessee depot, 115 mi |
Every price above includes delivery. If you would rather spread the cost, ask about rent-to-own when you call.
