Louisiana State Capitol renovation is bigger, longer than visitors may realize
Louisiana's State Capitol remains open during a major exterior rehabilitation that is expected to continue through 2028
BATON ROUGE, La. — Visitors to the Louisiana State Capitol may see scaffolding, closed entrances and construction activity surrounding the landmark building, but the work underway is more than a cosmetic renovation.
The state is undertaking a major, multiyear effort to preserve and rehabilitate the 1932 Capitol, with work focused on protecting the building from water intrusion, repairing structural components and restoring its distinctive limestone exterior.
And while some portions of the current project have specific completion targets, the larger preservation effort is expected to continue for years.
The current work
The Louisiana Division of Administration's Facility Planning and Control divided the current exterior rehabilitation into two major phases.
Phase 3 focuses on the Capitol tower, including the exterior limestone from the fourth through 34th floors. The work includes repairing, repointing and cleaning the limestone, addressing deterioration in the steel frame and brick substrate, restoring hundreds of bronze windows and doors, and repairing areas damaged by moisture intrusion.
State documents originally identified May 2027 as the anticipated acceptance date for Phase 3.
Phase 4 covers the lower sections of the building and was scheduled for completion in May through July 2028, according to the state's project documents.
That distinction is important: 2027 and 2028 are not a blanket completion date for every aspect of the Capitol's long-term preservation program.
Why is the work necessary?
The Capitol is nearly a century old, and state officials have identified water infiltration as a significant threat to the building.
Previous phases of waterproofing revealed deterioration in portions of the Capitol's structural steel caused by years of water intrusion. State records show that exploratory demolition was necessary in portions of the Temple section to determine the extent of the damage and help guide subsequent work.
The current project is therefore intended not simply to make the building look better but to address problems that could threaten its long-term structural integrity.
The exterior limestone also is receiving extensive attention. Rather than simply covering or replacing portions of the historic facade, the rehabilitation plan calls for carefully removing, repairing, conserving and reinstalling limestone where necessary.
The project also includes conservation work on the Capitol's bronze windows and doors and restoration of architectural elements that are part of the building's historic character.
The price tag is significant
The state originally established an estimated $115.5 million guaranteed maximum price for the current exterior waterproofing and rehabilitation project.
In 2025, state lawmakers and Gov. Jeff Landry allocated approximately $31.7 million toward the next phase of the work. State construction documents indicate that additional funding will be required as the project progresses.
The state's 2026 budget documents continue to identify Exterior Waterproofing at State Capitol Building as a capital project, with additional funding being pursued for the work.
That continuing need for appropriations is one reason the entire preservation effort cannot simply be assigned a single completion date.
What visitors can expect
The Capitol itself remains open to visitors.
The Louisiana Department of Culture, Recreation and Tourism currently lists the building as open from 8 a.m. to 4:30 p.m. daily, with certain holiday exceptions.
However, visitors should expect construction-related changes.
The observation deck is closed for renovations. Explore Louisiana currently says the 27th-floor observation deck is expected to remain closed until late 2027, although the reopening date could change as construction progresses.
The building's historic exterior also remains surrounded by construction activity as rehabilitation work continues.
Visitors should check current access information before making a trip, particularly if they are traveling specifically to see the observation deck.
A landmark being preserved for another century
The Louisiana State Capitol was completed in 1932 and remains the tallest state capitol building in the United States.
Its significance goes beyond its height and architecture. The building has been at the center of Louisiana's political history for nearly a century and has witnessed some of the state's most consequential moments.
For Baton Rouge residents and visitors, the construction may be inconvenient in the short term. But state officials and preservation professionals say the objective is to ensure the Capitol remains structurally sound and historically intact for generations.
The key takeaway for visitors is simple: the Capitol is open, but the renovation is far from finished.
Phase 3 is targeted for completion in 2027, while Phase 4 extends into 2028. The broader preservation program, however, is expected to continue beyond those dates as additional work and funding are approved.
In other words, 2028 should not be presented as the date when every renovation at the Louisiana State Capitol will be finished. It is the anticipated completion window for the current Phase 4 work.
