City halls across Tennessee are getting more than stern lectures about the housing crisis. They are getting tools. The Tennessee Housing Development Agency has rolled out interactive data and modeling that show where homes are not being built fast enough and which residents are getting squeezed out. THDA staff say the idea is simple: give mayors, planners and county commissioners hard numbers so local policies, from zoning tweaks to financing tools, actually line up with real demand. For fast growing Clarksville and smaller markets like Cookeville, the agency is trying to move the conversation from big promises to pinpointed action.
“We are in a once in a generation housing crunch,” Dr. Dhathri Chunduru, THDA’s director of research and planning, told Tennessee Town & City. The outlet reports that, in the Clarksville area, household formation rose about 15% while population grew roughly 11%, and that only about 26% of recent home sales were affordable to a median income family there. TML notes local officials estimate roughly 3,500 additional units are needed in the region to meet current demand.
THDA’s statewide analysis scales up that local snapshot. Its 2026 Housing Market at a Glance finds Tennessee will need roughly 315,000 new homes by 2035 to keep up with growth and replace aging stock. According to THDA, the Greater Nashville cluster alone may require more than 160,000 new units over the next decade if current trends hold.
Tools That Map Demand And Need
THDA’s public tools break the statewide story down to counties and development districts, with data on tenure, income bands, age of housing stock and affordability indicators that local leaders can compare across communities. As detailed by Tennessee Town & City, the Housing Indicators Dashboard and the Regional Housing Needs Model let users see who is cost burdened and what kinds of units a community is short on. That level of detail, agency staff say, can steer choices about starter homes, preservation, or where deep subsidies are actually required.
How Cities Can Use The Data
Beyond maps and metrics, THDA is positioning itself as a finance guide. The agency can help municipalities set up a Multi family Tax Exempt Bond Authority to fund affordable rental housing and can point cities toward opportunities in the Low Income Housing Tax Credit pipeline. According to THDA, the agency also offers technical assistance to communities that ask for it, with [email protected] listed as a contact for help.
Local options THDA staff highlight range from land banking blighted lots, to adjusting minimum lot sizes so more homes can be built on the same land, to regional coordination that lets neighboring jurisdictions share tax and financing tools. The point is not one magic fix, but a menu of strategies that can be matched to what the numbers show.
Supply Plus Subsidy, Not Supply Alone
THDA’s research push comes with a reality check for anyone hoping the market will simply build its way out of the crunch. Coverage by the National Council of State Housing Agencies reports that more units will help, but building alone will not solve affordability problems for extremely low-income households. The analysis cited in that coverage cautions that supply-side measures have to be paired with targeted subsidies and preservation programs if the most vulnerable renters are going to stay housed.
For policymakers and planners, the takeaway is that the data are not just for show. They are meant to help match the right tool, whether it is a zoning change, bond financing or rental assistance, to the specific need in each community. Local officials who want help getting into the dashboards or turning model outputs into on-the-ground policy can reach out to THDA’s research team to request technical assistance.
