Six important things about the proposed affordability zoning changes on Capitol Hill

mha_draft_zoning_changes_first_hill_capitol_hill15% of Seattle is slated to be rezoned to allow for taller buildings as part of Mayor Ed Murray’s Housing Affordability and Livability Agenda. The largest concentration of rezones includes a swath of land covering downtown, Capitol Hill, and the Central District.

Most of the area’s multifamily housing zones would get the standard “HALA bump” — a one story increase in allowable building height along with new “mandatory housing affordability” requirements for all new residential construction. As part of Seattle’s “Grand Bargain,” MHA will link the creation of affordable housing with market-rate development by requiring all new multifamily buildings to make 5-11% of their units affordable or require developers to pay into an affordable housing fund. That part of the program has already been approved by City Council. Over the next year the city will hammer out how to handle the zoning.

Much of the First Hill-Capitol Hill urban center residential zones would receive the one-story bump along with a requirement that all new development include 5-7% of affordable units. Some would be required to meet higher affordability mandates. But the devil is in the details, and there are plenty of details to sift through when it comes to the zoning maps on Capitol Hill.

1. Auto-row incentives (probably) maintained

The Pike/Pine Conservation District is a unique incentive zoning program in Seattle responsible for most of the auto-row preservation projects on Capitol Hill. Changes proposed under the HALA map appear to undercut the program, but a upcoming tweak to the building code would likely keep those incentives in play.

Under the preservation program, developers get to build seven stories instead of six for preserving an old building facade in Pike/Pine. In the proposed HALA map, an up-zone in Pike/Pine would automatically allow for seven-story buildings. While preserving a facade would still get developers a one extra story, it seems unlikely they would take it. Building codes mandate that any building higher than seven stories must be entirely concrete or steel framed instead of wood, making an eight-story project vastly more expensive.

However, a recent change in the building code set to take effect in January will allow for five stories of concrete or steel construction under three stories of wood. Officials from the Office of Planning and Community Development say that will help make the preservation program pencil out, although more tweaks could be needed.

“As we refine this initial draft MHA proposal, we will ensure the Pike/Pine preservation incentive remains effective,” said OPCD spokesperson Jason Kelly.

Now the only question is whether there are any character buildings left worthy of Pike/Pine-style preservation.

2. No M2s on Capitol Hill

In the draft HALA maps, city planners used the letter “M” to denote several things: where MHA requirements would apply, the relative leap in zoning, and how much affordable housing developers would need to build or fund. Here’s how it breaks down:


Capitol Hill has plenty of M and M1 areas, but no M2s as it lacks any up-zones dramatic enough to trigger the highest level of affordability requirements (one M2 requirement, for example, will be placed in an area transitioning from a single family home zone to a neighborhood commercial zone).

Those committed to allowing for the highest amount of density possible will likely lobby the city to include more dramatic up-zones in Capitol Hill’s densest areas.

3. Daytime development on Broadway

Business owners along Broadway (and all over Capitol Hill) have long been pining for more daytime office activity on Capitol Hill. HALA’s zoning maps could help make that happen.

Both sides of Broadway between Howell and E Roy are slated for an up-zone that would allow for seven story buildings with commercial use throughout the entire building (currently, commercial uses are only allowed in the first four stories). That could bring a large office project or (another?) hotel to a part of Capitol Hill many say is in desperate need of daytime foot traffic.

4. The Madison corridor

Chief among the HALA principles is that denser housing should be built around major transit centers. Several low-rise zoned blocks east of the Capitol Hill Station would go to mid-rise zones and be required to have a second-tier (M1) level of affordability.

During last week’s Pike/Pine Urban Neighborhood Council, some members were disappointed to see that the Madison corridor was not slated for a similar up-zone given plans for a new Madison Bus Rapid Transit line. Currently, the low-rise zones just off Madison Ave are only slated for the standard HALA bump instead of an M1 level of affordability.

5. Up-zoning I-5

PPUNC has been a leading proponent of the Lid I-5 campaign which envisions creating a lid over a section of the interstate to connect Capitol Hill and downtown with green space and possibly new development.

While it’s unclear how exactly a new lid would be zoned or even who would be responsible for zoning it (that section of I-5 is managed by the state), members of PPUNC want to get out in front by rezoning the area to allow for the highest possible development. PPUNC is currently drafting a list of HALA rezone recommendations that will include larger up-zones to the areas directly under I-5.

6. Dealing with displacement

HALA represents a massive push to encourage the creation of thousands of new affordable apartments, but what happens when that new construction displaces existing “organic” affordable housing? The Central District and other neighborhoods were identified as areas at risk of such displacement in the Seattle 2035 report published in May.

In response to these concerns, Mayor Murray recently announced that new developments in the Central District would be required to include an even higher level of affordable housing than initially announced.

Under the update, the high-MHA geographic area has been expanded to include the Central Area and some areas of Capitol Hill. Developers of new projects in these areas would be required to make 7 to 11% of their units affordable to those at or below 60% AMI.

“Requiring developers to build affordable housing or contribute to its construction helps us slow the rate of displacement caused by our city’s growth, making MHA a critical tool for ensuring our city remains affordable for everyone,” Murray said in a statement.

  1. I have a hard time reading the map. Could someone please translate what this means for the neighborhoods off Union between 23rd and 19th?

  2. Not sure if this change will increase or decrease land values seeing as the increase comes and an expense of creating space that is less valuable as far as income goes.

  3. Yes, building a concrete and steel structure at only 8 floors is silly so this is mostly a ridiculous proposal as many won’t opt for it.

    On Capitol Hill, lets build 20-30 floor structures along arterials where the costs of development in concrete and steel are more viable when building at that scale.

  4. The Madison zoning is a problem. If the city is going to spend a boatload of money on a rapid ride investment, they are going to have to upzone Madison and environs. I wish the city would deal with it now rather than pretend it isn’t happening or (god forbid) reneg on adopted policy.
