Incentive Zoning for Affordable Housing

In certain zones, incentive zoning allows commercial and residential developers to achieve additional development capacity when they provide for affordable housing. Chapter 23.58A and Chapter 23.49 of the Land Use Code, depending on the location of the development seeking extra floor area, provide the regulatory framework for incentive zoning.
