What is an Affordable Housing Agreement?
An affordable housing agreement is a contractual arrangement between a developer and a municipality requiring a portion of new housing units to be sold or rented at below-market rates. These agreements help ensure long-term affordability within new developments.
Why an Affordable Housing Agreement Matters in Real Estate
Affordable housing agreements matter in real estate because they support housing policy goals, increase supply of affordable units, and balance market-rate development with community needs. They are a key tool in addressing affordability challenges.
Example of an Affordable Housing Agreement in Action
A condo developer signs an affordable housing agreement with the city, setting aside 20% of units as affordable rentals for 25 years as a condition for project approval.
