Intro:
Ah, rent calculation—the sacred art of determining exactly how much someone should pay for a roof over their head without accidentally breaking federal law. If you've ever tried to calculate rent across HUD programs, you've probably asked yourself: Why are there 14 different ways to do the same thing? Welcome to the chaos of American housing policy, where math meets madness and no two formulas are ever quite the same.
This blog is for anyone who has stared blankly at a tenant file whispering, “Is that gross income or adjusted?” or for those brave souls who dared to calculate rent without a calculator—and lived to tell the tale.
Wait... Why Isn’t There Just ONE Way to Calculate Rent?
Because housing policy in America is like a potluck dinner: every agency brings their own dish, and no one agrees on what goes into the casserole. Here's a taste:
The Many Faces of Rent Calculation:
Program | Key Calculation Style | Common Pitfalls |
HUD Section 8 (HCV) | 30% of adjusted monthly income (which includes deductions for things like dependents and medical expenses) | Forgetting to deduct child care, or using gross instead of net. |
Permanent Supportive Housing (CoC) | Also 30% of adjusted income, but documentation standards can vary, and PSH may have special rules around zero income or utility allowance credits. | Not verifying third-party income correctly. |
NYS Supportive Housing (OMH, HRA) | Some use 30% of gross income, some 30% of net, some include SSI back pay, others don’t. It’s choose-your-own-adventure depending on the funder. | Not following the right manual (or realizing there is one). |
Rapid Rehousing (RRH) | Typically 30% of monthly adjusted income—but the key difference? Participants' rent contributions change frequently as income fluctuates. | Forgetting to recalculate after income change. |
