Valley houses and hillside basements
Powell's long, narrow valley means many lots slope toward Beaver Creek or up the ridges. Sloped lots are where daylight and walk-out basements are common, and those lower levels are often being finished into bedrooms and family rooms. If a basement room will be used for sleeping, it needs an emergency escape opening; see egress windows for sizes and window wells.
Knox County, not the city
Most of Powell lies outside Knoxville city limits, so permits go through Knox County Codes Administration rather than the City of Knoxville, although some parcels near the I-75 and Emory Road interchange have been annexed. Check which jurisdiction your address falls in. Either way, Knox County's Home Improvement license rule applies to $3,000 to $24,999 residential jobs.
Common window jobs in Powell
- Builder-grade sliders and single-hungs in 1980s and 1990s subdivisions, replaced with vinyl windows.
- Older farmhouses near the original Powell Station area, where wood sashes may be worth repairing.
- Kitchen and bath swaps to casement windows, which are easier to open over a counter.
Glass for valley weather
A house tucked against Copper Ridge or Beaver Ridge may lose direct sun early on winter afternoons, which favors glass with a moderate solar heat gain coefficient that lets some warmth in. Houses in the open valley floor with exposed west walls do better with lower SHGC. The 2018 IRC floor for Knox County is U-0.32 and SHGC 0.40.
