Deck Construction Permits in Montgomery

Local Rule

City of Montgomery Building and Inspections Department

The city's own site plan guidance states that any attached deck or elevated platform structure requires a permit in Montgomery regardless of size, while a detached ground-level deck above an unpublished square footage threshold also triggers the requirement; the 200 square foot figure used here follows the general Alabama IRC baseline rather than a confirmed Montgomery-specific citation for the detached case. Montgomery's own accessory-structure threshold is 144 square feet, distinct from the 120 square foot figure most Alabama cities, including nearby Birmingham and Huntsville, use as their default.
