Deck Builder in Florence, AL — Permits, Costs & What to Expect

Florence has a large number of homes with rear yards that are well-suited for decks — the terrain is relatively flat in most Florence neighborhoods, lots are typically generous, and the proximity to the Tennessee River means outdoor living is a priority for many homeowners. We build decks regularly throughout Florence and Lauderdale County, and there are specific local considerations worth understanding before you start planning.

Deck permits in Florence, AL

The City of Florence requires a building permit for any deck attached to a home, and for freestanding decks above a certain size. The permit process involves submitting a site plan showing the deck footprint and its relationship to property lines, a framing plan showing joist and beam sizing, and footing details. The building department reviews the plans for code compliance — particularly setbacks from property lines — and a framing inspection is required after the framing is complete but before the decking is installed.

We handle all permit applications for deck projects in Florence. Skipping the permit is a significant risk: an unpermitted deck creates title complications when you sell the home, voids your homeowner's insurance coverage for deck-related incidents, and may require demolition if discovered during an inspection. Every deck we build in Florence is fully permitted and inspected.

The ledger board — the most important detail

For attached decks — the most common type — the ledger board is the board that connects the deck frame to the house. It's the most structurally critical element and the most common point of failure in decks built without permits or proper oversight. The ledger must be attached to the house's rim joist or band joist with lag screws or structural bolts at the correct spacing, and it must be properly flashed so water doesn't work its way between the ledger and the house framing. Improper ledger attachment and missing or inadequate flashing are responsible for most deck collapses and the vast majority of moisture damage at the deck connection point.

In Florence homes — particularly older homes near downtown and the UNA campus — the rim joist situation isn't always straightforward. Some older homes have minimal rim joists or unconventional framing that requires adaptation. We assess the attachment point before finalizing the deck design to make sure the connection is structurally sound.

Pressure-treated vs composite decking in Florence

Structural framing — posts, beams, joists — is always pressure-treated lumber rated for ground contact. For the visible deck surface and railings, you have two main choices:

• Pressure-treated decking: Lower upfront cost ($15–$25/sq ft installed), requires sealing every 1–2 years to prevent graying and cracking in Alabama's sun and humidity. A well-maintained PT deck lasts 20–30 years. A neglected one deteriorates significantly faster.
• Composite decking: Higher upfront cost ($28–$45/sq ft installed depending on the brand), but requires essentially no maintenance — no sealing, no staining, no splinters. In Florence's climate, the heat retention of composite on a south-facing deck is worth considering; we recommend lighter colors for full-sun applications.

Cost ranges for deck construction in Florence, AL

• Basic pressure-treated attached deck (12×16): $12,000–$20,000
• Composite decking (same size): $20,000–$32,000
• Multi-level or large deck with stairs and railing: $28,000–$55,000+
• Screened porch addition over existing deck: $18,000–$35,000
