Read the local context
Williamson County has spent the past four decades becoming Tennessee's wealthiest county by median household income, and Franklin's growth -- along with neighboring Brentwood and Spring Hill -- has followed that prosperity outward from the historic downtown into new construction across the county. That combination of an affluent, still-growing homeowner base and a housing stock spanning nineteenth-century in-town homes to fast-built modern subdivisions keeps plumbing, HVAC, foundation, water damage, mold, and gutter work in consistent demand across the Franklin service area.
Ask what will be hidden
Williamson County's housing spans nineteenth-century in-town homes to fast-built modern subdivisions, and sizing a plumbing, HVAC, foundation, water damage, mold, or gutter project starts with matching the scope to how that specific house and lot were built, not a generic checklist. The written scope should explain the preparation and verification that will no longer be visible at completion.

Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
What official local sources add
The City of Franklin's Stormwater Management program, overseen by the Engineering Department under a state Phase II MS4 permit, manages drainage into the Harpeth River and its tributaries, while the Historic Zoning Commission reviews exterior changes within Franklin's designated historic districts near downtown and Main Street. Homeowners in or near a historic district should confirm local review requirements before exterior work, and all Franklin-area owners should verify parcel-specific drainage and flood conditions with the city before major foundation, plumbing, HVAC, or exterior work begins.
