How long does it take to build a deck in Blue Ridge GA?

The full timeline from signed contract to usable deck runs 4 to 10 weeks in Blue Ridge. That includes 1 to 3 weeks for Fannin County permit review, 1 to 2 weeks for material lead time, 1 to 2 weeks for construction, and 1 to 3 days for final inspection. Sloped lots and composite material orders push toward the longer end.

How much does a 20x20 deck cost in Blue Ridge?

A 20x20 deck (400 sqft) costs roughly $12,000 to $15,200 in pressure-treated lumber or $16,000 to $22,000 in composite, installed on a mountain lot. Those ranges include Fannin County's deeper footing requirements and typical slope adjustments. HomeAdvisor's national estimates run lower because they assume flat-lot construction.

Do I need a permit for a deck in Fannin County?

Yes. Any deck attached to a house or any freestanding deck over 200 square feet requires a building permit from the Fannin County Building Department. Permit fees typically run $75 to $200 based on project valuation (verify with the Building Department for current rates). Georgia law also requires a licensed contractor for projects exceeding $2,500.

How much does terrain or slope add to deck construction cost?

Sloped lots in Blue Ridge typically add $8 to $20 per square foot to deck construction costs compared to a flat lot. The surcharge covers elevated post systems, drilled piers for rocky ground, limited equipment access, and drainage engineering on hillside sites.

Is composite decking worth it for a rental cabin?

For rental cabins, composite decking usually pays for itself within 3 to 5 years. The higher upfront cost ($40 to $55/sqft vs. $28 to $38/sqft for pressure-treated) is offset by zero annual staining costs and higher guest appeal. Composite boards don't splinter, which reduces liability risk for barefoot guests.

What is the most expensive part of building a deck?

On mountain lots, the foundation work (footings, posts, and structural framing) is typically the most expensive component, accounting for 35% to 45% of total project cost. Fannin County's 18- to 24-inch footing depth requirement and the need for taller posts on sloped sites drive this higher than metro Georgia builds.
