Castilleja School

Rendering of proposed Castilleja School plans

Castilleja School, 1310 Bryant Street, Palo Alto

Castilleja is a private, all-girls’ school for 6th through 12th grades, located at 1310 Bryant Street at Embarcadero Road in Palo Alto. The school has been at the current site, which is zoned Residential -- Single Family Residential (R-1) 10,000, since 1907, and is surrounded by single family homes.

In the year 2000, Castilleja received a use permit from the City of Palo Alto for an enrollment of 415 students. 13 years later, the City discovered that Castilleja’s enrollment exceeded this allowance and initiated code enforcement actions including a significant financial penalty, a requirement that the school begin to reduce its enrolment, and a requirement that the school apply for a new use permit to request any increase above the permitted amount.


Pending Application

For the 2018-2019 school year, Castilleja informed City staff that student enrollment is 434 students. On June 30, 2016, the school submitted requests for a new conditional use permit to increase student enrollment and to allow for phased redevelopment of their campus, including construction of an underground parking structure in phase one. The use permit application seeks approval to increase the total number of students over a 4-5 year period, with the addition of no more than 27 students per year. The application (File# 16PLN-00238) and other materials provided by the applicant can be accessed to the right of this page.
