Staff clarifies when TIRZs must set aside increment for affordable housing

Jul 15, 2026

Committee staff explained that TIRZs created by petition must set aside one‑third of their increment for affordable housing, while non‑petition zones may include affordable housing goals in project plans without an immediate spending requirement; the county’s one‑third contribution will go to the county affordable‑housing office under current arrangements.

The full story

A staff member from Council Member Panzarella's office asked how affordable housing appears in a TIRZ project plan and whether it creates binding obligations. Andrew Busker explained that TIRZs created by petition (property owners requesting a zone) are statutorily required to dedicate one‑third (0.333) of their increment to affordable housing, while non‑petition zones may list affordable housing as a project‑plan goal and later decide how to implement it.
