Frequently Asked Questions
Why is Huntsville's housing market so different from other Alabama cities?
Huntsville has an unusually high-wage economy for Alabama — anchored by Redstone Arsenal (Army's largest missile/rocket center), NASA Marshall Space Flight Center, and Cummings Research Park (US's second-largest research park at 3,800+ acres). These defense, aerospace, and technology employers pay significantly higher salaries than Alabama's average, driving home prices well above Birmingham, Montgomery, or Mobile. Huntsville has been among the fastest-growing US cities by percentage — a trend not typical for Southern Alabama cities.
Can I build an ADU on my Huntsville property?
Yes. Huntsville allows accessory dwelling units on single-family lots under the Huntsville Zoning Ordinance. Maximum size is typically 800 sqft for detached ADUs. Alabama has no statewide ADU law — Huntsville's local code governs. Building permit from Development Services required. Huntsville Utilities connection fees apply for independent utility service. No owner-occupancy requirement.
What is Twickenham and does it have special rules?
Twickenham Historic District is the largest antebellum residential district in the Southeast — an extraordinary collection of Greek Revival and Federal-style homes in downtown Huntsville. If your property is in Twickenham or Old Town Historic District, you may need a Certificate of Appropriateness from the Huntsville Historic Preservation Commission for exterior modifications. This applies to roofing, windows, additions, siding changes, and visible alterations. Contact Development Services to check your property's designation.
