Renovating an aging hospital or replacing it is among the most expensive questions a health system asks, and the condition report that usually drives the answer covers only part of it.
When Allegheny Health Network committed to replacing its Canonsburg hospital with a new campus at Southpointe, it retired a building that had served patients for more than a hundred years. Plenty of systems are working through the same choice right now with buildings half that age. Keep investing in the hospital you have, or replace it. Owners tend to begin by assessing the building’s condition, which is the part of the problem that is easiest to measure and the least likely, on its own, to settle the question.
The decision is showing up across the whole capital cycle. After several deferred years, hospital construction has picked back up, and ConstructConnect’s data shows much of the new spending concentrated among a small group of well-funded systems building ground-up replacements; roughly fifteen projects worth more than a billion dollars were announced in 2025. At the same time, a study commissioned by ASHE, the American Hospital Association’s facilities arm, found that U.S. health care facilities had deferred roughly 41 percent of their maintenance, a backlog estimated near $243 billion. One month of headlines tends to capture the range: a 120-year-old hospital coming down for a new campus, a system clearing aging buildings to make way for a 621,000 SF expansion, a closed hospital site that took years to attract a workable redevelopment plan. The owners behind those projects reached different conclusions, and the age of the buildings was seldom what decided it.
What the condition index leaves out
The standard instrument is the Facility Condition Index, which divides a building’s deferred maintenance by what it would cost to replace it. A hospital with $25 million in deferred work and a $250 million replacement value scores at ten percent. ASHE’s Capital Renewal Playbook recommends that hospitals and other critical buildings hold near five percent, with outpatient and administrative space allowed closer to ten. Past roughly thirty percent a building is generally treated as being in poor shape, and once deferred maintenance approaches sixty percent of replacement value, a straightforward economic comparison usually favors building new.
There is real value in this. The index gives an owner a consistent way to compare buildings across a portfolio, and it keeps one persuasive story about one building from steering an entire capital plan. Any owner weighing the choice should have current condition data in hand. The problem comes when the score is allowed to stand in for the decision.
The question that matters is whether the building can support the care model the system expects to be running a decade from now, and what bringing it to that point would cost.
An index of this kind measures what it would take to bring a building back to good working order. It has little to say about whether good working order amounts to fit for purpose. A hospital can score well and still be the wrong building, because physical condition and functional capacity are different things that happen to share a roof. The forces reshaping care make the distinction concrete. The Advisory Board projects close to $50 billion in volume moving from inpatient to outpatient settings, and clinical models are reorganizing around ambulatory access and same-day work. Older buildings carry limits that maintenance cannot lift. Floor-to-floor heights and column grids fixed decades ago often cannot accommodate the mechanical systems and room dimensions that current imaging suites and operating rooms require. A building can be structurally sound and functionally out of date at once, and a condition index will not flag it, because the index was built to track upkeep rather than suitability.
That reframing is what changes the answer. The question that matters is whether the building can support the care model the system expects to be running a decade from now, and what bringing it to that point would cost. Spending heavily to restore a building to excellent condition for a service line that is about to move offsite puts real money into preserving something the organization is on its way to leaving.
Four questions to work through first
Before an architect lays out options, an owner can move through a short sequence, in order, since each question shapes the next.
Start with whether the site will still serve its population in ten years. Demand moves. Much of the most active replacement work in the country is following population growth into the suburbs while older urban campuses are left with a service area that has shifted around them. If the location no longer matches the demand, condition stops being the point, and the real choice runs between rebuilding somewhere better and adapting in place for a market that is thinning.
Then price what renovation costs once the work of operating around it is included. A budget that compares only hard construction dollars against a new build usually reads in renovation’s favor.
Next, establish whether the existing structure can physically carry the care model the system is committing to. This is an engineering question about floor heights, column spacing, and mechanical capacity, and it returns a definite answer. A building that cannot hold the clinical program belongs in the replacement column whatever its score, and a building that can hold it with reasonable work belongs in the renovation column even when it looks worn.
Then price what renovation costs once the work of operating around it is included. A budget that compares only hard construction dollars against a new build usually reads in renovation’s favor. Building inside a hospital that has to stay open adds costs that ground-up work avoids: phasing, swing space, infection control, temporary infrastructure, longer schedules, and the disruption to live clinical services. These rarely make it into the first comparison anyone runs, and leaving them out yields a figure the project will never meet.
Finally, ask whether the finished renovation hands the system a building it would have chosen to build. When a renovation lands within reach of replacement cost and still produces a compromised facility, the cheaper-looking path turned out to be the costlier one. Replacement delivers a clean program, current code, and decades of service life. Renovation delivers a constrained program inside an envelope shaped for another era. Each should be priced against what it provides, not against the other.
Where the decision belongs
The common belief is that renovation is the careful, economical route and replacement is the extravagance. That holds in some cases. In others the numbers sit closer together than expected. BSA’s 2026 analysis puts general hospital construction between $430 and $470 per SF, with specialized facilities reaching $650 to $800 and the highest-cost markets like New York and the Bay Area routinely clearing $700 on the strength of union labor, permitting, and constrained sites. Escalation has eased from its 2022 to 2023 peak to somewhere near two to four percent, reopening a planning window that had effectively shut. Against those numbers, a deep renovation of a complex building, phased around live operations, can come close to replacement cost while returning much less of the benefit. Treating renovation as automatically cheaper skips the work that would show whether it is.
The way the decision tends to go wrong is undramatic. An owner who has not yet settled what the facility needs to accomplish commissions a condition assessment, receives a recommendation framed around condition, and adopts it as strategy. The consultant did capable work and answered the question they were given, which concerned the building. The larger question, the one about care model and population and the next twenty years, never reached the people with the authority to answer it.
This is the pattern to watch for. A renovate-or-replace call is a strategic position the owner sets and then asks the technical work to test, rather than a recommendation handed up for the owner to ratify. The condition assessment, the cost model, and the structural review are inputs to a judgment that stays with the owner. The systems that handle it well tend to stop weighing buildings one at a time and start asking how each facility decision strengthens their capacity to deliver care a decade out. They settle what success looks like on their own terms, and then they measure the building against it, treating the condition score as one input to a decision that remains theirs to make.
