To qualify for the Affordable Housing Overlay zone, there must be 100% affordable units on site. For rental units, at least 80% of the units shall be initially occupied by households with gross annual income under 80% of AMI. Remainder of units shall be initially occupied by households under 100% of AMI. Rent, utilities, and fees should not exceed 30% of gross household income. For-purchase units, at least 50% of units should be sold to households with gross income under 80% of AMI. Remainder of units should be sold to households with income under 100% of AMI. Monthly housing payments should not exceed 30% of monthly income of 70% of AMI (in former case) or 90% of AMI (in latter case). AHO projects are allowed a higher maximum height, there is no minimum lot area, there is no required off-street parking, and the yard setback requirements are generally less restrictive than existing zoning.
