Chattanooga officials propose voluntary zoning incentives to add permanently affordable units

City of Chattanooga housing staff on a council meeting presented a proposed Voluntary Incentives Program (VIP) that would give developers zoning relief in exchange for new units kept affordable in perpetuity.

The program, presented by Laura Monroe, director of housing policy for the city, would offer a set of land‑use incentives — most notably a 30% density bonus, reduced parking minimums and, in strong markets near transit, an additional 30% height bonus — in return for affordable units restricted at 80% of area median income (AMI) or below and protected by a 99‑year deed restriction.

Monroe said the proposal grew from more than a year of work by the mayor’s office and partners to change state law so municipalities could offer incentives tied to affordability. "This is a completely voluntary new program that offers some zoning incentives in exchange for the development of new affordable housing," Monroe said, adding that the city sees the proposal as a way to "ride the wave of new development" without committing city funds.

Why it matters: Chattanooga faces what presenters described as a housing mismatch and affordability gap. Monroe cited city data showing 44% of households earn less than 80% AMI and said rental prices have risen steeply since 2020. Presenters also said the city has an estimated gap of about 14,000 one‑bedroom units compared with household composition, which favors smaller households.

Program details presented - Project types and affordability requirements: developments of 5–9 attached residential units (type 1) would need to provide one affordable unit; projects with 10 or more units (type 2) would be required to keep 10% of units affordable at 80% AMI or below. A third category (type 3) would permit a 30% height bonus for qualifying projects in strong‑market areas and within 500 feet of a transit stop, provided they meet the other standards.

- Incentives: a 30% density bonus (implemented as a reduction in required minimum lot size rather than changing setbacks or building envelope), reduced parking minimums (not a cap on actual parking supply), elimination of certain parking landscape requirements for larger projects and a conditional 30% height bonus in designated strong markets near transit.

- Affordability and compliance: all affordable units created through the program would be restricted in perpetuity by a 99‑year deed restriction. The proposal includes a noncompliance civil penalty; as presented, staff said a $5,000 per‑unit civil penalty per year would apply for noncompliance and that the deed restriction would include enforcement provisions.

- Application and approval process: the program would be developer‑initiated. An applicant would submit a letter of interest to the Regional Planning Agency (RPA) and the city’s Housing and Community Investment (HCI) team, attend a pre‑application conference, submit a complete application within 120 days, and then receive review by the regional planning commission under a by‑right ("ministerial") approval path if the project meets program criteria. After approval, the city would record deed restrictions and HCI would carry responsibility for compliance and rent/income verification.

City staff emphasized the tool is intended to leverage market activity: Monroe said more than 4,000 multifamily units have been permitted in the city in the last five years, and the VIP is designed as a voluntary, market‑driven option that requires no direct city subsidy.

Concerns and limits discussed Council members asked about geographic scope (zoning districts that already allow five or more multifamily units), layering with other city pilot programs, applicability to redevelopment or conversions, short‑term rental rules and the program’s reach for lower‑income households. Staff said redevelopment converting nonresidential space to housing could qualify if a developer proposed new residential units that meet zoning and program criteria; staff also said the program is likely to produce affordability roughly in the 70–80% AMI range without additional subsidies but could be layered with the city’s housing pilot to reach deeper affordability (for example, 60% AMI or below).

On short‑term rentals, staff said the deed restriction and the program’s compliance tools would address misuse of affordable units and that the city already limits short‑term rentals so that no more than 25% of units in a building can be used for short‑term vacation rentals under existing ordinance rules. Monroe said: "The 5,000 per unit civil penalty per year of noncompliance." HCI staff would administer compliance and verification for income‑restricted units.

Next steps Staff said they have drafted program guidelines that incorporate the state law changes and plan a six‑month evaluation, followed by an annual review, to adjust incentives in response to developer feedback and market results. The council did not take a formal vote on the program during the presentation; staff indicated the proposal would return for council action and concurrent processes with planning commission and code updates would be set up following council consideration.

Ending City staff framed VIP as a voluntary, zoning‑based tool to encourage privately funded affordable units where density is already allowed and where market conditions make additional incentives effective; eventual adoption would require council action and coordination with the regional planning commission and city legal staff.
