Buying Land in Montgomery County, Tennessee

Two zoning codes, one shared planning commission

Montgomery County has adopted its own countywide zoning resolution covering unincorporated land -- a version dated February 2024 was the most recent found in this research pass -- distinct from the City of Clarksville's separate City Zoning Ordinance, which governs parcels inside city limits. Both are administered through the Clarksville-Montgomery County Regional Planning Commission (CMCRPC), which handles zoning-change recommendations for both jurisdictions but routes them to different final decision-makers: recommendations affecting unincorporated county land go to the County Commission, while those affecting Clarksville parcels go to City Council.

For a buyer, that means confirming which of the two documents -- the county resolution or the city ordinance -- actually governs a specific parcel is the necessary first step, and it's not always obvious from an address alone given how much Clarksville's corporate limits have likely expanded through annexation over time in a growing metro area. Pull the current zoning map for the specific jurisdiction from CMCRPC directly rather than relying on an older cached version, especially given the county resolution's relatively recent 2024 amendment.

Fort Campbell's real, codified land-use footprint

Fort Campbell, home to the 101st Airborne Division and one of the largest military installations in the country, straddles the Tennessee-Kentucky state line with a substantial footprint in Montgomery County. Its presence isn't just an economic-development talking point here -- it shows up directly in the county's own land-use regulations. Montgomery County's subdivision regulations include specific provisions addressing what's described as the Fort Campbell Noise Zone, and the county's planning commission materials describe ongoing, direct coordination with Fort Campbell's own Planning Division on development decisions near the post.

In practical terms for a land buyer, that means a parcel's proximity to Fort Campbell can carry genuine, codified land-use consequences beyond a generic 'near a military base' consideration: noise-contour zones tied to flight operations and training activity, and potentially accident-potential-zone-style setback or use restrictions common near active military airfields, can affect what's permitted or advisable to build on nearby land. Confirm a specific parcel's noise-zone or accident-potential-zone status directly with CMCRPC or the county planning office before assuming standard residential or agricultural zoning rules apply without qualification near the installation, and factor in that Fort Campbell's mission and footprint can change over time, making this worth reconfirming rather than relying on an older map.

This framework goes back further and runs deeper than a single subdivision-regulations section: a four-county Joint Land Use Study (Montgomery and Stewart counties in Tennessee, Christian and Trigg counties in Kentucky) was completed in 1996, leading to a standing Fort Campbell JLUS Partnership formed in 1998 and updated in 2009, built around the federal AICUZ (Air Installations Compatible Use Zones) program's noise-contour and Accident Potential Zone guidance. Our dedicated page on housing mitigation near Fort Campbell covers how that framework actually restricts and mitigates incompatible development in more detail.

A growing metro, plus the statewide framework

Beyond the Fort Campbell-specific considerations, Montgomery County has been one of Tennessee's faster-growing counties in recent years, driven partly by the base's steady population and partly by broader spillover growth from the Nashville metro area to the south. That growth pressure shows up in more active zoning-amendment activity and subdivision development than a typical rural Tennessee county, reinforcing the importance of pulling current zoning and subdivision-regulation documents rather than older ones.

Septic system permitting in Montgomery County follows the statewide TDEC Rule 0400-48-01 framework described on our Tennessee state page; much of Clarksville's urbanized core is likely served by municipal sewer rather than septic, but outlying county parcels should still confirm septic feasibility directly. This research pass could not independently confirm a specific Montgomery County Health Department address or phone number with sufficient confidence, so use the Tennessee Department of Health's own local health department directory to find the current contact and confirm processing times before treating any parcel as build-ready.
