The City of Austin may provide developers with incentives—such as fee waivers, density bonuses, tax incentives, and development agreements—to build and to set aside affordable rental and ownership housing for low- and moderate-income households in developments.

SMART Housing

The City of Austin SMART Housing program provides fee waivers for development permits in exchange for onsite income-restricted units.

Learn about SMART Housing

The S.M.A.R.T. (Safe, Mixed-Income, Accessible, Reasonably-priced, Transit-Oriented) Housing program is designed to stimulate the production of housing for low-and-moderate income residents of Austin. To participate in S.M.A.R.T. Housing, developments must provide a certain level of affordable housing, meet certain accessibility and green building standards, and satisfy requirements related to proximity to transit. The City of Austin provides certain fee waivers (including Permit, Capital Recovery, and Construction Inspection fees) and S.M.A.R.T. Housing development review for certified developments.

For further information, please see the S.M.A.R.T. Housing guide and S.M.A.R.T. Housing section of the Land Development Code. Development within the University Neighborhood Overlay (UNO) is also required to meet certain S.M.A.R.T. Housing thresholds. For further information, see UNO information under the Overlays tab.

Density Bonuses

Density Bonuses allow developers to build more units than are allowed by a site’s base zoning if the developer agrees to set aside a portion of units for income-restricted affordable housing or, in some cases, pay a fee, known as a fee-in-lieu. The affordable housing units must be income-restricted and leased or sold to a low-income or moderate-income household for the required affordability period.

You may view details on the City of Austin’s density bonus programs by viewing the Developer Incentive Matrix or visiting the drop-down menus below. Examples of density bonuses include the Downtown Density Bonus, University Neighborhood Overlay (UNO), Transit-Oriented Development, East Riverside Corridor, and North Burnet Gateway Density Bonus.

Affordability Unlocked

Affordability Unlocked is a development bonus program that waives or modifies some development restrictions in exchange for providing affordable housing. In return for setting aside half of a development’s total units as affordable, developments can receive increased height and density limits, parking and compatibility waivers, and reductions in minimum lot sizes. The program is designed to increase the number of affordable housing units being developed in Austin and fully leverage public resources by allowing housing providers to build more units in their developments when significant amounts of affordable housing are included.

To apply for Affordability Unlocked, please fill out the online application.

Please visit the Affordability Unlocked program website for more information, including a program guide.
