The City bought 555 Kelly Avenue in 2017. In November 2021, the City Council asked staff to pursue affordable housing there.
In February 2022, the City issued a formal Request for Qualifications (RFQ) seeking a developer for affordable housing at 555 Kelly Avenue. The RFQ encouraged a maximum height of three stories. Mercy Housing and Ayudando Latinos A Soñar (ALAS) submitted the only response.
By 2023–2024, the proposal was a five-story building with 40 apartments and 18 on-site parking spaces.
One reason the project could qualify for additional height under State Density Bonus Law was the City's 2024 determination that the site was within one-half mile of a “Major Transit Stop.”
A Major Transit Stop is a term defined by California law. It includes a rail or bus rapid transit station, a ferry terminal served by transit, or a location where qualifying major bus routes meet and provide frequent peak-hour service.
For 555 Kelly, the City combined nearby fixed-route SamTrans service with Ride Plus on-demand service and concluded that the combined service was equivalent to a Major Transit Stop.
The Planning Commission approved the Coastal Development Permit in May 2024. The City Council upheld that permit after an appeal hearing in June.
In December 2024, the City Council resolved that it would not use on-demand transit to qualify a location as a Major Transit Stop unless State law directed otherwise. However, the 555 Kelly Coastal Development Permit stayed in place, although the Council determined that Half Moon Bay does not have a qualified Major Transit Stop.
In spring 2026, the Council approved Ordinance No. 2026-01. It authorized a long-term Ground Lease and related housing-development agreements. A referendum petition received enough valid signatures to qualify. The Council then placed the ordinance before voters as Measure Q.

Read the election information
Why is this on the ballot?
The referendum challenged Ordinance No. 2026-01, which authorizes the long-term Ground Lease and related housing-development agreements. It did not repeal the separate Coastal Development Permit approved in 2024.
What Measure Q decides
Ordinance No. 2026-01 is adopted, allowing the Ground Lease and related agreements authorized by the ordinance to take effect according to their terms.
Ordinance No. 2026-01 does not take effect. The separate 2024 Coastal Development Permit remains in place and it gives the City an opportunity to reconsider project terms.
