Rent control laws in major cities like New York and San Francisco were meant to protect low-income tenants, but I've seen landlords in my neighborhood let buildings decay rather than fix them up, knowing they can't raise rents enough to cover repairs. A friend who owns a small apartment building told me he's lost over $30,000 a year under rent stabilization, so he simply stopped maintaining the units. Should we keep rent control when it may reduce the quality and supply of housing?
