Why great-room addition × Orlando produces this band

A great-room addition scope for a home addition in Orlando combines two price levers: scope and metro labor rates. A great-room addition opens the existing floor plan and pushes out with a large light-filled space — typically 400-700 SF with high ceilings, large spans, and often a cathedral or vaulted ceiling. Requires structural engineering. Against the national median remodel labor rate, Orlando runs 10% below the national median — so the great-room addition band comes in 25% above the mid-range, then scales 10% below the national median on top of that. Permit timelines for residential work in Orlando typically run 4-10 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Orlando bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

What drives cost for a great-room addition scope

What makes Orlando different

Labor — Inland location keeps labor away from HVHZ-only restrictions — broader trade pool.
Labor — Tourism-industry remodel cycle drives steady demand in Kissimmee + Lake Buena Vista.
Labor — Retiree + second-home market in Winter Park and Baldwin Park produces consistent premium-finish work.
Material — Central Florida material distribution is served by Tampa and Jacksonville ports — competitive pricing.
Material — Termite-resistant construction (pressure-treated, borate-treated) is a region-specific material cost.

Orlando rules that affect this scope
