A revolving construction loan fund to unlock permitted housing that can’t get built — without new federal dollars.
Philadelphia has 2,930 housing units in 39 apartment projects that hold a live building permit and have gone a year or more without taking the next step. They can break ground immediately — no new zoning, no reinstatement, no policy change. Most sit in the city’s strongest markets, where a mixed-income building puts affordable homes in high-opportunity neighborhoods instead of concentrating them. The bottleneck isn’t regulation, it’s financing. In today’s interest rate environment, construction loans cover roughly 50% of project costs, down from 65%+. Developers must fill the gap with private equity demanding double-digit returns, making many projects financially impossible to start.
The Housing Production Fund would be a revolving construction loan fund providing low-cost subordinate financing to get permitted projects built. It replaces expensive private equity with patient public capital — then recycles that money into the next project when the construction loan converts to permanent financing. This is not an acquisition fund or a preservation fund. It is construction money for new housing.
Subordinate construction debt at below-market rates (1–5%) replaces expensive private equity in the capital stack.
~70% market-rate, ~30% affordable at 50–100% AMI. Cross-subsidization means no LIHTC or federal funding needed.
Loans repaid in 3–5 years at permanent financing conversion. Same dollars fund the next project indefinitely.

A permit-extension holiday for permits that lapsed since January would add 7 more projects and 1,078 units, for 4,008 in total.
39 shovel-ready apartment projects totaling 2,930 units hold live building permits and have stalled. Every council district has them.
Philadelphia would join Montgomery County MD ($100M, 731 units built), Chicago ($135M), Atlanta, Massachusetts, Michigan, and a growing national movement. The model won the 2024 Ivory Prize for Housing Affordability.
