Altadena Main Library Renovation Project

The Altadena Main Library Renovation Project, led by the Los Angeles County Department of Regional Planning, involves a comprehensive upgrade of the facility located at 600 E Mariposa St, Altadena, California. The scope of work includes expanding the building footprint by approximately 700 square feet, performing a seismic retrofit, and reconfiguring interior spaces. Key infrastructure improvements focus on replacing aged mechanical, electrical, and plumbing systems, including the elevator and HVAC systems, and adding accessible restrooms. The project also incorporates modernized audio-visual spaces, updated communications infrastructure, and structured cabling. Exterior enhancements include a new entry lobby, community room deck, outdoor reading court, delivery loading zone, and updated signage, along with parking lot resurfacing and landscaping upgrades. The project is governed by the California Environmental Quality Act (CEQA), with a Draft Environmental Impact Report addressing air quality, noise, and cultural resources. Construction is scheduled to occur in phases from May 2025 through March 2026, beginning with demolition and grading, followed by interior and exterior construction and final architectural coating. Performance goals emphasize universal design to exceed ADA requirements and the preservation of the building's mid-century modern design. Strict compliance is required for the handling of asbestos-containing materials and lead-based paint, and all work must adhere to the California Building Code and Standard Specifications for Public Works Construction.
