Crews are deep into a two-year overhaul of Burton Barr Central Library, replacing the entire fire suppression system inside the 280,000-square-foot building at 1221 N. Central Ave. while also patching sections of its roof. The work began in November 2024 and is expected to run through late 2026, forcing the city's flagship library to juggle heavy construction with its usual flow of visitors.
The project, confirmed by the City of Phoenix, covers two simultaneous efforts: a full swap of the fire suppression piping throughout the building and repairs to various roof sections. Construction has already meant temporary parking restrictions and limited access to spaces like Pulliam Auditorium, and as The Arizona Republic reports, Phoenix is upgrading Burton Barr's entire fire suppression system as part of the broader capital improvement push that began in late 2024.
To keep the doors open, the library is tackling the sprinkler replacement floor by floor rather than shutting down entirely. Phoenix Public Library says it moved first-floor collections and services in mid-2026 as part of that phased approach, a strategy aimed at preserving public access across the building even as pipes and fixtures get torn out and replaced.
A Building That Already Flooded Once
The push to replace the fire suppression system traces back to a July 2017 monsoon storm that exposed just how vulnerable the building's aging pipes had become. Fifty-mile-per-hour winds lifted roof tiles and blew dust into the facility, setting off smoke detectors that in turn triggered corroded sprinkler pipes to burst, according to PHOENIX Magazine. Between 50 and 60 gallons of water per minute poured across all five floors, ruining roughly 8,000 books and forcing an 11-month closure of the building.
What made the 2017 flood especially painful was that it may have been preventable. A post-flood investigation found that internal inspection reports had warned city staff about severe sprinkler pipe corrosion for up to three years before the disaster, according to KTAR News. Then-City Manager Ed Zuercher went on to discipline 11 city and fire department employees for failing to act on those warnings.
The 2018 restoration that followed carried a hefty price tag. Fixing the damage ultimately cost $11.5 million — covered by $9.4 million in insurance proceeds and $2.1 million pulled from library reserves — and included a new roof and a rebuilt fifth-floor sprinkler system before the building reopened that June, according to KJZZ. Initial estimates had pegged the repair cost at just $6 million to $8 million before the scope expanded.
Fixing the Whole Building This Time
That 2018 fix only addressed the fifth floor and the roof above it. The current project goes much further, replacing the fire suppression system across the entire building rather than patching a single section, reflecting a more comprehensive approach to a facility that has already proven what a single storm can do to unmaintained infrastructure.
Burton Barr isn't just a functional public building — it's also an architectural landmark. Opened in May 1995, the 280,000-square-foot library was designed by DWL Architects and Will Bruder and funded by a 1988 voter-approved municipal bond, replacing a 1950s-era central library on McDowell Road that later became part of the Phoenix Art Museum campus. In May 2021, the American Institute of Architects gave the building its national Twenty-Five Year Award, citing its copper-clad exterior, five-story glass atrium, and adaptable layout.
The building's top floor houses a 1-acre Great Reading Room beneath a Buckminster Fuller-inspired tensegrity roof, with tracking skylights designed to cast circles of light onto the ground floor at solar noon on the summer solstice. That flexible roof design allows for slight movement during severe windstorms — a feature that contributed to the roof tile displacement during the 2017 monsoon.
Balancing Construction With a Busy Flagship Library
Overseeing the project is Erin MacFarlane, who became Director of Library Services for the City of Phoenix in July 2024 after 13-year City Librarian Rita Hamilton retired, as Hoodline previously reported. MacFarlane brings 26 years of educational and public library experience to the job, putting her at the helm just as the capital improvement work reaches its final stretch.
Burton Barr's importance to the broader system is hard to overstate. Beyond serving as the downtown flagship, the building alone houses a collection of 1 million volumes and the system's administrative headquarters, with 16 additional branch locations rounding out the Phoenix Public Library network. Major disruptions at Burton Barr ripple across that entire 17-location system, making the phased construction approach less a convenience and more a necessity for a building that hosts hundreds of thousands of visits every year.
