Will my North Alabama lot work for a barndominium?

The first question, because it changes every other answer. Inside city limits, or inside a city's planning jurisdiction where one extends past the limits, the city's building department, zoning ordinance and permit process apply no matter what the county does. Outside, the county's decision on building codes applies, and in most of this footprint that decision is no code. The tax parcel record shows the jurisdiction; a call to the city clerk confirms it.

The gate that closes most often. The county health department has to permit an onsite sewage system after a soil evaluation by a professional engineer, land surveyor, geologist or soil classifier, and a lot whose soil fails cannot carry a house without an engineered alternative or a different building site. Order the evaluation before closing, or make the purchase contingent on it. The septic guide covers the process end to end.

Check the FEMA flood map for the parcel before anything else about the site plan. Several counties in this footprint that run no building department still publish a flood damage prevention ordinance and require a development permit for anything built in a special flood hazard area, through the county engineer or a flood management office. Etowah, Cullman, Morgan, St. Clair, Lawrence and Limestone all show one on their official sites. Building in the floodplain without that permit is an ordinance violation, and a lender will not close on a house in a flood zone without flood insurance. The floodplain and driveway permit guide has the county list.

A new driveway onto a county road usually needs a permit from the county road department or engineer, and often a culvert pipe set to the county's specification. Cullman County's Road Department handles driveway pipe permits; Blount County publishes a driveway access permit; Lawrence County publishes a pipe or access permit with no fee. The permit is not a formality: a post-frame delivery is a long truck, a concrete pour is several heavy ones, and an entrance the county has not approved can be dug out at your expense.

On a private road or an easement, read the easement. Width, maintenance obligations and whether construction traffic is allowed are all in the document, and none of them is the builder's problem.

Distance to the nearest power line is a real cost, paid to the utility before the builder can run a temporary service, and it varies from nothing to tens of thousands of dollars on a long rural parcel. Water is either a rural water system tap, where the system's tap fee and line availability decide it, or a well, which is its own permit and its own risk on the limestone and sandstone ground here. Ask the utilities before you buy, in writing, and get the tap or extension cost in a quote. A barndominium plan does not change any of those numbers, but a lot choice does.

Rock, in much of North Alabama. The Tennessee River valley floor is limestone with karst features, which can mean shallow bedrock, sinkholes and drainage that behaves unexpectedly. Sand Mountain and the plateau from Albertville to Fort Payne and Scottsboro are sandstone, often close to the surface. The ridge-and-valley country toward Gadsden, Centre and Ashville mixes both. Rock affects the septic evaluation, the cost of a slab or footing excavation, and whether a basement or crawl space is realistic at all. A builder who has dug in your county knows where the rock is; ask. Slope matters too: a post-frame building wants a level pad, and moving dirt to make one is a line item.

Restrictive covenants outlive the subdivision that wrote them. Minimum square footage, prohibited exterior materials, no metal buildings, no outbuildings before the house, and setbacks larger than the county's all show up in older plats around Huntsville, Guntersville and Pell City. Read the recorded covenants for the parcel at the probate office or through the title company before you fall in love with a metal-sided plan. A covenant that forbids it does not care that the county has no zoning.

It matters for the schedule and for what your contract has to carry. In Madison County the lot goes through plan review and the house through inspections. In the counties that state or show no county building permit, the septic permit, the floodplain permit and the driveway permit are the county's whole involvement, and the standard the house is built to comes from the contract and from the licensing board's 2015 IRC backstop against a licensed builder. The permit guide has each county's stamp.

Jurisdiction, covenants and floodplain first, because they are free and they can kill the lot outright. Then the soil evaluation, because it costs money and decides the rest. Then utilities and access, because they set the site budget. Then the builder, with all of it in a folder, so the first conversation is about the house and not about whether there can be one. When that folder exists, send your county and your plan and it goes to a licensed local builder.
