Bulldozers have already cleared Mission Bay High School's old natural grass multipurpose field, and four teachers have packed up their classrooms for relocatable buildings near the tennis courts, as a sweeping, multi-year modernization of the 1953-era Pacific Beach campus gets underway. Students returned for the new school year on August 10, only to find their school in the early stages of a construction project that will not wrap up until January 2030.
The renovation, which carries a price tag of more than $25 million according to the district website, touches nearly every corner of the 55-acre campus, as reported by The San Diego Union-Tribune. The project's stated goals, per the district, include repairing and renovating aging building systems, improving energy efficiency and sustainability, and boosting accessibility and code compliance across the site. Classroom modernization alone will touch 21 additional classrooms, eight science classrooms, three art classrooms and three career technical education classrooms, the newspaper reports.
Portables Become the New Normal for Some Classes
For now, disruption is concentrated in a handful of relocated spaces. Four teachers have moved out of their classrooms and into relocatable buildings on the west side of campus near the tennis courts, while the campus's Junior ROTC program has similarly shifted its classes into relocatables as its main campus classroom awaits upgrades, according to the Union-Tribune's reporting. Four existing classrooms are being converted into temporary main office workspaces, and the school's front office itself is slated for a major remodel — with the main office expected to move into those temporary classrooms this winter.
Locker rooms are also mid-transition. The girls' PE changing room has already relocated to a larger relocatable building near the tennis courts, and the girls' locker room is being remodeled with new showers, restroom facilities, changing areas, lockers, team rooms and fresh paint. The boys' locker room renovation is planned for a future phase of the project, the paper notes.
New Turf, a Refreshed Auditorium and ADA Upgrades
The campus's old natural grass multipurpose field has already been removed to make way for a new synthetic grass field that will be lined for football, soccer, field hockey and lacrosse. That addition arrives as San Diego Unified has seen districtwide student-athlete participation climb 13% year-over-year, from 12,001 to 13,565 students, according to a July 2025 announcement from San Diego Unified.
Mission Bay High's 790-seat auditorium is also in line for a significant renovation, including new seating, ADA accessibility features, a new sound and lighting system for the stage, and new dressing rooms and a ticket booth. The upgrade matters for a campus whose music program includes the award-winning Mission Bay Preservationists jazz band and the Mission Bay Mambo Orchestra — described on Wikipedia as the only youth Latin big band operating in California. Elsewhere on campus, the cafeteria serving line will get new equipment and flooring, a new ADA-compliant restroom building is planned, and modernized classrooms will receive new flooring, window blinds, and interior and exterior paint. The front entrance along Grand Avenue will also see upgrades, the Union-Tribune reports.
Part of a Decades-Long Pattern of Upgrades
Mission Bay High opened in September 1953 as part of a broader expansion of educational facilities during the post-World War II population boom, and it has undergone various improvements and additions over the decades since. Commercial contractor Soltek Pacific Construction previously completed an earlier phase of Whole Site Modernization work at the school, including remodels of the administrative entry, kitchen renovations and classroom air conditioning installations.
The current project is funded through a series of voter-approved general obligation bond measures — Proposition S in 2008, Proposition Z in 2012, Measure YY in 2018 and Measure U in 2022 — that together back San Diego Unified's districtwide capital improvement program, per district bond documentation. California law prohibits those bond revenues from being spent on teacher or administrative salaries, restricting the funds strictly to facilities work. Nearby Pacific Beach Elementary School, part of the same school cluster, completed its own Whole Site Modernization in 2023, adding a new kindergarten facility and expanding joint-use playfields — a project Hoodline covered in Pacific Beach's earlier campus upgrade.
Renovation Arrives Amid Academic Momentum
The construction comes as Mission Bay High rides a wave of academic attention. Voice of San Diego reported in March that the school was the most-improved in San Diego County on its income-versus-test-score performance metric since 2021, climbing from a score of -62 to nearly +50, according to Voice of San Diego. The specialized classrooms slated for renovation, including science labs and art studios, support Mission Bay's status as one of only two San Diego Unified high schools — alongside San Diego High School — authorized to offer the full International Baccalaureate Diploma Programme for 11th and 12th graders.
Just months before construction began, the campus was also the debut site for a district initiative allowing schools to bill health insurers for on-campus student mental health services while keeping care free for families, a rollout Hoodline detailed in March. The modernization also unfolds against a statewide backdrop of shrinking public school enrollment — California's K-12 enrollment fell by nearly 75,000 students, per state data cited by the district in August — even as San Diego Unified runs summer enrollment drives aimed at attracting new families. How the district and school administration will manage instructional disruption through the full 2026-2030 construction timeline, as students and staff continue cycling through temporary portable classrooms, remains an open question as the project moves forward.
