Valuation: What Illinois Building & Construction Businesses Sell For in 2026
Florida's ongoing construction boom — driven by population growth, hurricane replacement, and commercial development — creates exceptional demand for licensed contractors. Florida contractor licensing is complex: Certified Contractor licenses are personal and not transferable; Registered Contractor licenses are entity-level and transferable. This distinction is critical for buyers and sellers to understand before any transaction.
For a detailed breakdown of how building & construction businesses are valued nationally, including add-backs, normalization methodology, and comparable transaction data, see our Building & Construction Business Sales Guide.
