I’m a huge opponent of how cities use zoning to keep densities very low and prevent people from moving into a neighborhood to enjoy high quality public schools and good access to transit. This is evidenced by many of my tweets about zoning analyses in Chicago over the last two weeks, and many blog posts I’ve written over the years.
I’m a proponent of Accessory Dwelling Units. In Chicago these are most commonly seen, in practice, as coach houses, which were built before most of us were born. ADUs, because they’re behind the primary building on a lot, are a nearly-hidden, low-impact way to provide affordable housing for a couple more people per lot without affecting the “character” of the neighborhood. And they generate rental income for the family that owns the primary building!
Coach houses, and ADUs, are illegal in Chicago. You’re allowed to keep the one you have, and it can be rented out to anyone else, so long as you don’t renovate it.
Bryn Davidson is an architect based in Vancouver, B.C., and his firm, Lanefab, designs ADUs in that city, a housing type that was legalized in 2009. He wrote an article in CityLab today and there are *so many quotable parts*.
In the article, Davidson offers five strategies for a city that’s developing an ADU legalization policy.
In the “Keep the approvals process simple” strategy, Davidson says that Vancouver’s policy means homeowners “don’t have to solicit feedback from neighbors”, adding, “The…is perhaps the most important. In North America we have a long history of granting neighbors truly extraordinary veto powers when it comes to adding new housing. Going forward, if we want to treat younger generations and renters more fairly, we need to stop trying to litigate housing on a lot-by-lot basis.”
This is one of the worst things about zoning today. Zoning is supposed to be the way that you tell property owners what they can expect to be able to build, and it’s a way for cities or residents to manage certain aspects about the way their area looks and who is living there.
But if everywhere in the city (cough Chicago cough) where people want to build is improperly zoned to begin with – for example, allowing only single-family houses near train stations in areas that have hundreds of apartment buildings that predate that zoning – you get a situation where so many property owners have to ask their city council member for a zoning change.
The next quotable is…the entire parking strategy. But here’s some choice parts:
- “We argued at length about parking in Vancouver, but in the end, opted to require only one onsite parking space…”
- “Some neighbors will get irate about the new competition for street parking, but here’s the counterpoint: If a neighbor is complaining about street parking, it’s because they’re using their garage…for something else”
- “Either way, a lot of single-family-home residents are parking on city property for free while extracting extra value out of their private land.”
Chicago is experiencing gentrification, with rising property values and taxes in neighborhoods filled with households that can least afford it. Many of these households live in a single-family house – what do you think about giving them the opportunity to renovate and rent out an existing coach house in North Lawndale, or build a new coach house in Humboldt Park?
