I will be out and about talking about the opportunities to make our cities more vibrant, equitable and affordable by ‘Greenzoning’ ie, putting more people’s homes near the jobs, parks, schools, in neighborhoods that already exist.

Events, Residential Small Lot

In Seattle thousands of residential lots are now ‘Residential Small Lot’ (RSL) as part of the MHA zoning reform. The rules covering RSL have been rewritten, bringing questions about how RSL will affect Seattle neighborhoods.

First, what is RSL and what kinds of new development are we likely to see?

Second, how does RSL address displacement, affordability, density or sustainability?

If you live in one of the affected urban villages or are interested in innovative infill housing RSVP below to join Matt Hutchins, AIA for monthly informational talks in a neighborhood near you. All engagements are from 5:00 - 6:30pm.

ADU reform is signed by Mayor Durkan!
Three generations share this lot, between the house and cottage

Three generations share this lot, between the house and cottage

Today, ADU reform passed. After 4 plus years of process we’ve made a huge leap forward in terms of creating flexible housing in Seattle. Here are my comments at the signing ceremony:

I’d like to thank Ronnie and Jerry for opening their home, and thank you Mayor Durkan for supporting this very progressive land use reform.  

As an architect, housing advocate, environmentalist, and  Seattleite, I think this is a watershed moment for our city.  Documents like the land use code are not generally very exciting, but can generate strong opinions because they are important statements of values. They often decide who gets to live where, in what kind of housing, where jobs are and how we get to them. 

  • We want people to be able to afford housing

  • We want people to have access to jobs, education, and open space.  

  • We want people to be near transit, and part of vibrant neighborhoods that are walkable and bikeable so we aren’t burning up the planet.  

  • We want to support households of all shapes and sizes, incomes, and ages.  

In the past, the way we’ve zoned cities hasn’t always reflected these values. It hasn’t been equitable, especially for communities of color, or sustainable.

This accessory dwelling unit reform begins to break down some of those barriers that have kept many people from building one for themselves. 

It will speed up permitting, make construction less expensive, and loosens up many of the restrictions. It will allow architects like me to focus on the challenge of designing great little homes for people. We know: 

  • ADUs are perfect for multigenerational households and people wanting to age in place or stay close to family. 

  • ADUs create flexible housing opportunities for those who don’t need a whole big house or want to live in a large apartment building. We haven’t had a lot of options in between. 

  • ADUs are great for those looking to share housing costs, or make some extra rental income

  • ADUs counter sprawl and lower our carbon footprint

This reform makes room for a few new neighbors in our residential neighborhoods, and that makes them stronger, more diverse and more welcoming.  

I look forward to the Mayor’s additional proposals to help people understand the process, explore city financing for affordable units and permit lower cost ADUs. 

I’d like to thank Councilmember O’Brien for his vision and resolve, and the hundreds of advocates that have turned out for abundant housing, especially Laura Loe, Sheri Newbold, Chrys Kim, Karen DeLucas, and Kirsten Smith at AIA Seattle. 

In 2015, when I started advocating for Accessory Dwelling Unit reform, I saw a possible future where my own kid wouldn’t be able to find a place to live in the neighborhood she is growing up in now. I didn’t think that it would take more than four years to get to this point today, but it has been worth it. We’re making a little more room to share this great city, one that we can all proudly call home.

Aging in (a New) Place: A flat with a big front porch, and two revenue streams!
Residential Small Lot will allow little stacked flats like this. How you use them is up to you!

Residential Small Lot will allow little stacked flats like this. How you use them is up to you!

If you are thinking about downsizing but don’t want to relocate to a new neighborhood, or to a tiny impersonal apartment in a big boxy building, there are very few choices out there.

Luckily, with Seattle’s Residential Small Lot Zoning (RSL), there are some fresh options. CAST architecture has been working with the land use code for about a year, and now that it is approved in many Seattle Urban Villages and Hubs like Crown Hill, West Seattle, Morgan Junction, and Roosevelt, we want to show off some of the possibilities to do density right!

We often lament that there are essentially very few single level living situations that aren’t little condos, and even fewer that have been built this century.

With this ‘Double Up’ Duplex, there are two primary residences, one at ground level, one up. Each primary residence can be configured with an Accessory Dwelling unit. At 2200 square feet per level Including the ADU), that could be a generous home with a built in rental stream. If someone wanted to develop the whole building, it would be perfectly legal to own the entire building, rent one level, and the ADU adjacent. Don’t want to be a landlord? It can be configured as a condo association.

Downsized, accessible, modern, super energy efficient living, with two revenue streams, not to mention a great front porch and big backyard!

On any RSL lot, we can design a two unit flat with accessory dwellings units.

We’re excited about what is possible under Residential Small Lot and hope that the best solutions get adopted far and wide!

New options for housing in Urban Villages with Residential Small Lot Zoning
Residential Small Lot zoning will create new housing options in established urban village neighborhoods

Residential Small Lot zoning will create new housing options in established urban village neighborhoods

Mandatory Housing Affordability passed City Council yesterday, and as part of that, about 7000 urban Single Family lots will now be able to have two or three primary residences (plus ADUs) on site. I’m pleased that we were able to suggest some amendments that will make the zone more workable, improve flexibility for sites where people would like to preserve the original house.

What is RSL?

In a nutshell:

1 primary residence per 2000 sq ft of lot (one ADU per primary residence allowed)

if your lot is smaller than 4000 sq ft, you could still do two residences.

Floor Area Ratio : .75

Lot coverage: 50%

Maximum size of any single primary residence: 2200sq ft.

Residential Small Lot Streetscape

Residential Small Lot Streetscape

While conceived as a kind of new ‘cottage’ zoning, it is better suited to compact 2 1/2 story urban houses.

We’ve come up with a prototypical design which maxes out all the limits, and it still feels pretty good within the existing streetscape. It is a 1500 sq ft upper unit, with main level suite, and open living/dining/kitchen (w/ twelve foot ceilings), two typical bedrooms and a second master on level two, with a patio/kitchen garden on the roof. In the basement (half below grade to avoid being counted toward F.A.R.) we’ve designed a 1 bedroom/1 bath Accessory Dwelling Unit, which could easily be integrated into the primary house, set up to generate revenue to help with the mortgage, or be co-owned like a two party condo association.

Because it is a relatively compact volume, with flexibility about solar orientation for a range of urban sites, hopefully we’ll get some owners interested in pursuing Passive House green building standards!

Residential Small Lot zoning: Courtyard bungalows

Residential Small Lot zoning: Courtyard bungalows

There is a real opportunity, once you start combining lots, to also aggregate the open space, and get back to that Courtyard Bungalow type that we used to build before zoning made them by and large illegal. Since parking isn’t going to be required for most, the market is going to dictate, but hopefully we’ll be spared a lot of impervious area creating more run off issues.

What is the RSL market and will any of it be affordable?

While I’m pretty excited about the eventual potential of this zone, there are very few neighborhoods where this is going to pencil (i.e. high priced, high demand markets).

1) it is happening where land values are going to be the highest (urban villages), but with the low density limits, land costs cannot be spread across more than 2 or 3 units for the most part—at minimum $300K of any newly developed unit is going to be for land value.

2) With low densities, it will be nearly impossible to provide new rent restricted housing on site. Nearly all development will pay the MHA fee (up to $45,650 per unit). With the ‘downzones’ to RSL that Council enacted with the late amendments taking many Lowrise areas a step back, it ensures than most of those areas will never see rent-restricted housing.

3) Similar to Vancouver’s market where the high cost of detached housing is tempered by ‘mortgage helpers’ like Laneway houses, ADUs are really the only new less expensive option, and that is purely because of the size of those units.

Envisioning Seattle's Residential Small Lot Future: May 23rd at the Ballard Library

Seattle is going to change thousands of residential lots from ‘Single Family’ to ‘Residential Small Lot’ (RSL) as part of the MHA zoning reform. The rules covering RSL have been totally rewritten and there are many questions about how it will affect our neighborhoods such as Crown Hill, West Seattle, and South Park

First, what is RSL and what kinds of new development are we likely to see?

Second, how does RSL address displacement, affordability, density or sustainability?

If you live in one of the affected urban village or are interested in innovative infill housing, join Matt Hutchins, AIA for this informational talk.
