Seattle renters, workers and people in non-monogamous relationships could gain new civil rights protections under a bill headed to the full City Council.

The Housing, Arts, and Civil Rights Committee recommended passage of CB 121278 on Wednesday, Sept. 9. The bill, introduced by Councilmember Alexis Mercedes Rinck, would update Seattle's definition of "sexual orientation" in the municipal code to explicitly include pansexuality, asexuality and consensual relationships with multiple partners.

The full council is expected to vote on the measure Tuesday, Sept. 15, according to a community page tracking the legislation.

That date has not been confirmed on the official council calendar.

The protections would apply to employment, housing, public accommodations, business licensing, park access and policing policies enforced by the Seattle Office for Civil Rights (SOCR).

Bisexuality is already a recognized orientation under city law. Pansexuality and asexuality would be new.

The bill also strips gender-binary phrasing such as "male" and "female" from the code's legal definitions.

One limit drew attention during the committee process: employers would not be required to extend health insurance, leave or other benefits to multiple partners.

Rinck's bill frames non-monogamous relationships as a protected expression of sexual orientation rather than a separate class, keeping the benefit question off the table.

A separate provision updates the existing "marital status" protected class so that cohabitation definitions include multigenerational families living together.

The SOCR can absorb initial enforcement within its current budget, Capitol Hill Seattle Blog reported. Department officials have requested up to $121,000 in supplemental funding during the 2027 budget cycle for community outreach and education.

If adopted, the policy would take effect in mid-2027. Seattle would join a small but growing list of cities with similar protections, including Portland, Olympia and several municipalities in Massachusetts and California, according to a staff presentation by committee analyst Tamaso Johnson. Caste was the most recent addition to Seattle's protected classes, added in 2023.

Johnson's presentation cited research estimating that 10–20% of North Americans have had a consensual non-monogamous relationship at some point. Roughly 5% are currently in one.
