A Seattle family is suing the city over its Mandatory Housing Affordability policy, which could charge them more than $75,000 in permitting fees to build on their property. The policy allows developers to build taller and larger buildings, and in return, they must either build affordable units or pay fees toward affordable housing to get permits in those neighborhoods. Though the program has raised significant funds, the Adams family argues it hurts families like them, who wanted to build on their existing lot to house their children and aging parents.
