The city of Seattle was supposed to be done with its 10-year comprehensive plan update more than a year ago, in December 2024. The comp plan is the document that governs local land use and zoning, which means it’s also about where the city will (and won’t) allow more density. As you know, it’s now 2026.

This should give you an idea of how many deadlines we’ve missed. Here we are, 14 months on, and pro-housing advocates are still waiting as the city braces for yet more debates over the specifics of the Neighborhood Center and Urban Center strategy that, sigh, continues to cordon density into tightly constricted areas.

We don’t have the luxury of waiting for the city to take action. It’s time to take matters into our own hands—at least as we wait for the new pro-density council members like Eddie Lin and Dionne Foster to join forces with Alexis Mercedes Rinck and new self-avowed urbanist Mayor Katie Wilson to get the zoning right. In the meantime, I’m hopeful about an emerging method to usher in the dense housing we need citywide to address the affordability and climate crises: Instead of fixating on wholesale land use changes, focus on discrete housing regulations with piecemeal reforms. Devious density.

I’m not advocating for timid tinkering around the edges. I’m thinking of ingenious hacks that are possible within the restrictive height limits, contorted floor area ratio guidelines, and setback requirements that currently define and limit the number of units you can fit into an apartment building. Like rearranging how you pack your suitcase rather than buying a bigger suitcase, affordable housing advocates should change the construction equation inside apartment buildings themselves.

Pro-density progressives in Washington state have already had success with this sneaky inside-out approach. In 2025, they won parking reform, which maximizes the square footage available for housing by lowering building costs and forgoing the need for carports and underground garages. Similarly, in 2023, advocates succeeded in passing the nation’s first-ever single-staircase bill, a reform that frees up space for more units in the same building footprint by getting rid of unnecessary two-staircase mandates.

Another recent bit of tactical urbanism, passed last year, made an exception to mandatory setbacks (the distance a building must be from the street and other lot boundaries) for smart construction methods like mass timber, passive house, and modular construction, as well as for affordable housing units.

In the current legislative session, pro-housing advocates are now on their way to passing elevator reform, which will lower costs for developers, hopefully hastening construction of more units.

As I reported last week: While the elevator industry stripped out a push for universal reform, urbanists are still set to pass a deceptively specific change at the ground level. The legislation will change elevator size guidelines for apartment buildings up to six stories tall, lowering costs and allowing more units. This detail-oriented code change will open the doors to multifamily housing in neighborhoods where the the overall zoning remains antagonistic to this type of renter-friendly development.

Consider this “within-the-envelope”-approach a pro-housing hack against the classic anti-density refrain about “neighborhood character.” (The housing “envelope” is the planning term for the ultimate size allowed for a development after all the setback, density, height, and other parameter guidelines are taken into account.) By adding the potential for more units within buildings that are visually in sync with the surrounding area, pro-housing advocates may reveal what intransigent NIMBYs actually mean when they say “character.”
