Parking is available in the underground parking structure just south-east of the Keith Spalding building (see Keith Spalding Parking Map or Morrisroe Parking Map).
Limited street parking may be available just south of the Morrisroe Bldg at the entry to Tournament Park.
For car parking, visitors must have a Caltech Parking Permit, which can be obtained from the pay station located at the California Blvd parking structure. Individuals with handicapped access must also display a parking permit, but otherwise follow regular handicapped parking regulations.
JPL personnel may use their JPL parking permits to park at Caltech. Colored JPL permits that are valid On-Lab are now valid in commuter spaces in all Caltech lots and structures. Qualified JPL personnel that do not have On-Lab parking privileges may obtain a temporary permit from the JPL Parking Office when they have a need to park at Caltech.
Hours of enforcement are Monday - Friday, 7 a.m. to 5 p.m. Red zones, fire lanes, no parking zones, handicapped spaces, and certain posted reserved spaces are enforced 24 hours a day, 7 days a week.
For visitors coming to Caltech, Caltech maintains a visitor webpage with information about parking, hotels and more. Please see: https://www.caltech.edu/about/visit/plan-your-visit.
