Calexico Carnegie Library
Also known as: Calexico Public Library
Why it's listed
Calexico's Carnegie Library, at 420 Heber Avenue, was built in 1918 from designs by the Los Angeles firm Allison & Allison. The city had requested $25,000 from the Carnegie program but was limited to $10,000, so the Spanish Colonial Revival design was simplified. The building measures 85 by 36 feet, with one story over a raised basement, a tile hip roof, stucco walls and a recessed central entrance. Concrete buttresses and gunite were added after the 1927 earthquake, and the building has survived later quakes with little damage. Inside, the maple floors, trim and original book shelves remain. It served as the public library until a larger one opened in 1986, then was used for storage. It is listed for its association with education and the later phase of the Carnegie library program. It also anchors an "intellectual park" that includes the old high school and historic city hall. The city has endorsed restoring it as a community technology library and historical center.
Significance in brief: The nomination argues it exemplifies community libraries of the later Carnegie program, when grants were smaller and tied to population. It also shows the range of Carnegie library design, here in the Spanish Colonial Revival style. It is part of the California Carnegie Libraries multiple property listing and anchors Calexico's planned "intellectual park."

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
