Here is today's Statesman article about the lack of affordable housing downtown.
The article really poses two questions: (1) "Should we have affordable housing downtown regardless of whether the market provides it?" and (2) "What's the best way to do it?"
The first question is debatable, but for present purposes I'll assume the answer is "Yes."
So how do we get moderately priced housing downtown? Although I've seen a lot of suggestions, they all appear to be variations on one of two strategies:
The first is affordable housing set asides or "inclusionary zoning": Require the developer to sell or rent X% of the units at an affordable price, regardless of their market price. Alternatively, allow the developer to pay the subsidy's cash equivalent into a City-owned affordable housing fund. (These set asides are not mandated by ordinance, but are usually extracted by the City in return for a zoning variance of some kind. They're a centerpiece of the new Vertical Mixed Use standards.)
The second is for the City to "buy" affordability by paying the difference between the market rate and the affordable rate. For example, if a unit's market price is $200,000, the City might pay the owner $50,000 to market it as a moderately-priced $150,000 unit, with covenants limiting the resale price. (I call $150,000 "moderately priced" because it's less than the City's median home price.)
The second is by far the better strategy, for a number of reasons:
- Requiring developers to include affordable housing screws with future supply. As I've pointed out here and here, when developers must set aside X % of their units at below-market rates, either fewer units get built or everyone else pays more. Either way, homes get more expensive on average. (Portraying the set aside as compensation for a "density bonus" doesn't change this fact.)
- Someone has to bear the cost when affordable units are sold below market price. Set asides disguise, but do not eliminate, that cost. When the City pays, the cost is transparent. This is important, because it forces us to ask the right questions. E.g., How much is it worth to have affordable housing downtown rather than, say, a few blocks to the south or east of downtown?
- When the City pays, there's an incentive to put the affordable units in the right places. It's a lot cheaper to put affordable units in a development where the units start at $200,000 than in a development where the units start at $500,000.
- If the City pays, we might see more pressure on the surrounding neighborhoods to open up their neighborhoods to more affordable, multi-family housing.
Set asides are nevertheless the more popular solution. The burden falls on the property owner (a very small constituency) or future home buyers (an unidentifiable constituency). In other words, set asides have nearly zero cost politically. Also, some very vocal entrenched interests benefit from rising average home prices.
If the City's bent on subsidizing affordable housing downtown, I think it should auction off a piece of property. Let developers bid for the right to build, say, 200 affordable units on the property. (If it is impossible to build affordable units for less than the sales price, the "high" bidder will be the one who asks for the least amount of money.)
This will be the most cost-effective way of providing affordable housing. It will also minimize the difference between the units' market price and their predetermined "affordable" price. This is important for avoiding three types of economic waste: (1) A unit sold below market price may be "overdeveloped" -- i.e., it may include upgrades that cost more than they are worth to the buyer; (2) a unit sold below market price does not necessarily end up with the person who values it most; (3) below-market sales create the opportunity for arbitrage, which can be prevented only through costly monitoring. An auction gives developers an incentive to minimize these kinds of waste.
Although this strategy will probably end up costing the City less than any other "City pays" strategy, it's not free even if it is off-budget. If the City could have sold a piece of property for $5 million, but instead gives it to a developer for free to build 200 affordable units, it has paid a $5 million subsidy. (With these hypothetical numbers, the City's subsidy would be $25,000/unit.) Still, I suspect this will get us the most affordable housing downtown at the least out-of-pocket expense for the City.
