Frequently Asked Questions
How does the University of Tennessee affect Knoxville's housing market?
The University of Tennessee's approximately 30,000+ students create intense rental demand in neighborhoods adjacent to campus — Fort Sanders, Laurel Avenue, and the Old North Knox corridor. This rental pressure has driven up property values in campus-adjacent areas. For ADU investors, these neighborhoods offer strong rental demand. Note that Fort Sanders is a historic district with design review for exterior changes. UT sports (Volunteers) also drive short-term rental demand on game weekends.
Can I build an ADU on my Knoxville property?
Yes. Knoxville allows accessory dwelling units in qualifying RN (Residential Neighborhood) zones. Maximum size is typically 750 sqft for detached ADUs. You'll need a building permit from Plans Review and Building Inspections. Tennessee has no statewide ADU law — Knoxville's local zoning ordinance governs. No owner-occupancy requirement. KUB connection fees apply for independent utilities.
What is the Metropolitan Planning Commission and does it cover Knox County too?
The Knoxville-Knox County Metropolitan Planning Commission (MPC) serves both the City of Knoxville and Knox County through a joint planning function. This is relatively unusual — Knoxville city and Knox County maintain separate governments but share planning services through the MPC. For property within Knoxville city limits, you work with Knoxville's Plans Review and Building Inspections for permits. For Knox County unincorporated areas, the county has separate permitting.
Does Knoxville have historic preservation requirements in Fort Sanders?
Yes. Fort Sanders is a National Register Historic District with Victorian architecture adjacent to the UT campus. Properties in Fort Sanders and other historic overlay (H-1) zones may require a Certificate of Appropriateness from the Knoxville Historic Zoning Commission for exterior modifications including additions, window replacements, roofing, and visible alterations. Contact Plans Review and Building Inspections to verify your property's historic status before beginning work.
What is KUB and how does it affect solar installation in Knoxville?
KUB (Knoxville Utilities Board) provides electricity, natural gas, water, and wastewater service to Knoxville and surrounding areas. KUB distributes power from TVA (Tennessee Valley Authority). For solar installations, you'll need KUB interconnection approval after receiving your electrical permit. KUB participates in TVA's net metering program. KUB also offers a Green Power Switch program for renewable energy support. Knoxville receives approximately 4.7 peak sun hours/day — viable for solar investment.
