Fence or deck costs in Montgomery

Montgomery sits on a patchwork of soils. Alabama Extension calls the mix around Montgomery, Prattville and Wetumpka unlike any other region of the South. Sandy and loamy uplands sit beside river terraces and the clays of the Black Belt prairie.

Those clays are the ones to watch. Some are alkaline, over soft Selma Chalk, and some are acid. Extension says both can swell when they're wet and shrink when they're dry, opening large cracks during dry spells. It flags the acid clays as a problem for structural foundations. Ground that swells and shrinks can lift or drop deck footings unevenly. On a fence, you see it as posts that lean or work loose. If your yard is on that clay, ask your builder how deep the footings go.

The rain sets the rhythm. At the airport, December through March is the wettest stretch on average, and October is the driest.

Who issues your permit depends on where the house sits. Montgomery County requires a building permit for any structure over 200 square feet, but only outside the police jurisdictions of the City of Montgomery and the Town of Pike Road. The city's police jurisdiction reaches three miles past the city limit, so a house that looks rural can still fall outside the county's permit area. In a flood-prone area, the county requires building to its Floodplain Prevention Ordinance, in effect since December 2025.
