Pasadena City Council is scheduled to hear an appeal tonight, Monday, March 2, 2026, over the approval of a four-story research-and-development building proposed for a Caltech-owned parking lot at 1364 E. Green Street. The site sits directly beside St. Philip the Apostle School, and parents, parishioners, and neighborhood groups say the project's scale and proximity raise safety, traffic, and construction-impact concerns.
What the proposal would build
The plan calls for a four-story, roughly 93,539-square-foot R&D center with office and laboratory space sitting atop a three-level, 260-space subterranean garage, according to the City of Pasadena staff report. The building is designed by Gensler and proposed by TC LA Development/Trammell Crow on land owned by Caltech; Caltech's project page describes the idea as an "innovation center" on Green Street and notes construction was anticipated to begin in 2026. City project documents show the development would replace an existing surface parking lot at the southeast corner of Green Street and Holliston Avenue.
Neighbors say it's too big and too close.
Opponents have mounted a sustained campaign arguing the project's massing and location are incompatible with the block and too close to the school's playground; the petition calls for "right-sized" development and contends the plan exceeds a 51-foot neighborhood height standard and lacks a full environmental review. Parents and parishioners raised those points during Design Commission hearings last winter, where extensive public comment focused on height, sight lines into the playground, and construction impacts, as reported by Pasadena Now. Those community concerns are the basis of an appeal that pushed the project to the City Council agenda.
How has the city reviewed the project so far
City planning staff recommended Concept Design Review approval and concluded the project is categorically exempt from the California Environmental Quality Act under the infill exemption (Section 15332), subject to conditions, according to the staff report. The Design Commission reviewed revised plans and asked the developer to restudy the fourth-floor massing along the south elevation and to reduce the prominence of the rooftop mechanical screen before final design review. Staff documents also summarize technical studies on traffic, noise, and air quality that the city says do not show significant impacts to nearby sensitive receptors like the school.
How the appeal works and what the council could do tonight
An appeal of a Design Commission action brings the dispute to the City Council, which can deny the appeal, modify the commission's conditions, or send the matter back for additional review. The City calendar lists a 6:00 p.m. council meeting on March 2, and Pasadena Now reported that an appeal filed Feb. 9 by Building a Better Pasadena is the item sending the project to the council. If the council denies the appeal, the project would proceed to Final Design Review; if the council upholds it, the city could require further study or design changes.
Timeline and what's next
Caltech's project page describes the Green Street site as an innovation center, and notes construction was anticipated to begin in 2026, though opponents say ongoing hearings or legal challenges could delay that timetable. Community organizers and parents say they'll press councilmembers for additional environmental and safety safeguards, and the petition alleges technical reports contain "inconsistencies and inaccuracies" that should be addressed before final sign-off, per the petition.
Tonight's vote will determine whether the design advances toward construction-level review or is sent back for more study, a decision that supporters say will keep jobs and lab space in Pasadena while neighbors warn it could permanently reshape a residential block next to a TK-8 school.
