In California, high-rise safety rests largely on owners

A re-inspection effort for aging towers might be prudent in the Golden State. Who would pay?

- By Teri Sforza and Kate Selig

Despite the tendency of the Earth to convulse beneath them, some 20,000 buildings that are 14 stories tall or higher have sprouted in California, according to internatio­nal data.

They’re office buildings and residentia­l towers. They’re in Long Beach and Los Angeles, Irvine and Oakland, San Jose and San Francisco, Glendale and Riverside.

Some of the oldest have towered majestical­ly over the landscape for 100 years, surviving earthquake­s, weather and time. But what’s happening below?

In California, no government agency is required to probe the bones of aging highrises to ensure they’re safe. Once a local city or county issues a certificat­e of occupancy — the final step in the building process, meaning people can move in — the government’s work is essentiall­y done. It’s left to building owners and residents to ensure high-rises are structural­ly sound as the years go by, which can lead to conflict. Residents have balked at hefty special assess

ments — sometimes hitting $100,000 per unit — that have been required to shore up aging infrastruc­ture.

Here, California’s reputation as a hyper-regulator is grounded in myth, not fact.

Florida’s two largest counties are far stricter, mandating that aging high-rises be inspected at age 40, then every 10 years thereafter. Of course, re-inspection requiremen­ts don’t guarantee safety: Years after warnings about cracks and leaking in its garage, Champlain Towers South crumbled to dust in the night, killing some 140 people as they slept on June 24. The homeowners associatio­n knew there were problems for years but couldn’t corral a consensus to do much about it.

As California’s high-rise dwellers gaze out floor-toceiling windows and highrise workers head back to the office, many are wondering: Would a Floridasty­le re-inspection regimen for aging towers be prudent in the Golden State?

‘Such a rare occurrence’

Engineers note that California has some of the strictest building requiremen­ts in the nation, thanks to its perch atop so many earthquake fault lines. But there’s always room for improvemen­t.

“Failures like the one in Miami are such a rare occurrence,” said Henry M. Koffman, professor of civil and environmen­tal engineerin­g at USC’s Viterbi School of Engineerin­g.

“Should we have inspection­s? Yeah, we should have inspection­s. You might find one out of a million cases in the U.S. — but that one out a million may save lives. It’s a balancing act, a trade-off. There are thousands and thousands of structures — to go around and inspect all of them takes an army. Who’s going to pay for it?”

A decade ago, Koffman was summoned by a homeowners associatio­n to inspect an aging high-rise in the L.A. neighborho­od of Westwood. It had problems similar to Champlain Towers South: A swimming pool over a two-level garage, showing structural cracks.

It needed more than $10 million in repairs. Residents balked but eventually agreed to a pricey special assessment. He only wishes Champlain South could have had a similar outcome.

“When I first saw the pictures, it looked like a bomb blast. Oklahoma City. Domestic or internatio­nal terrorism,” he said.

Bay Area high-rises

The Bay Area is home to hundreds of high-rise buildings, some dating back to the early 1900s. But building experts in the area said the age — and lack of re-inspection­s — is not cause for concern.

San Francisco alone is home to nearly 500 highrises, according to emporis. com, a database for building informatio­n worldwide, with some residentia­l condos, such as Bellaire Tower, which was built in 1930. In Oakland, the BellevueSt­aten, a residentia­l condo with a view of Lake Merritt, has become one of the city’s famous buildings since its constructi­on in 1929.

Chu Chang, the chief building official of San Jose, said it doesn’t make much sense for the government to re-inspect aging condos. He worried that such a measure could even do more harm than good if residents felt complacent about fixing problems with the knowledge that an inspection would take place a few years down the line.

“If you live in a singlefami­ly home and there’s water coming down from your ceiling, you do something because you own the house,” he said. “You don’t sit there waiting for the government to come in for recertific­ation. You don’t add another level of government bureaucrac­y if your roof is collapsing.”

Instead, San Jose focuses on regularly inspecting structures to ensure they’re meeting fire safety codes. The city also inspects buildings with renters and other residents who don’t own their living spaces to make sure that the structures are up to code. Those tenants, Chang said, are the ones most at risk since they don’t own the building. “That’s where you focus if you want to protect people,” he said.

Whose job is it?

California’s Building Code is a constant work in progress. Right now, updates to its many rules governing electrical, mechanical, plumbing, building and other codes are being drafted for adoption, which happens every three years.

There’s no statewide law or code requiring mandatory structural/engineerin­g reviews after a certain time period for high-rises, and there are no proposals for one on the table right now, said Jennifer Iida, spokeswoma­n for the California Department of General Services.

“A post-occupancy inspection program generally is not a requiremen­t in a building code,” she said by email.

After the collapse of a balcony killed six people in Berkeley in 2017, however, the state Legislatur­e approved a new law requiring most multifamil­y buildings with exterior stairs and balconies to be regularly inspected.

The responsibi­lity for reviewing building plans, issuing building permits and declaring structures safe and ready to occupy isn’t the state’s bailiwick — it’s the job of California’s 480-plus city and 58 county building and planning department­s.

Those cities and counties could decide to adopt more stringent, Florida-style re-inspection programs for their older high-rises if they so choose.

“Enforcemen­t does fall to the cities, although California has a state building code. Local municipali­ties can adopt amendments, and many do, but they must be at least as strict as the state requiremen­t,” said Thomas A. Sabol, professor of civil and environmen­tal engineerin­g at UCLA’s Samueli School of Engineerin­g, by email.

“Other than buildings subject to mandatory seismic upgrades — e.g., nonductile concrete buildings in L.A., West Hollywood, and Santa Monica, or tuckunder/soft-story apartments in these cities — there is little in the way of mandatory re-inspection once a certificat­e of occupancy has been issued.

“Based on my experience reviewing existing buildings, I haven’t seen many examples of significan­t structural damage or distress in the absence of an outside cause (e.g., an earthquake), but this doesn’t mean it doesn’t exist. Most of the buildings that I think require remedial attention are those that have seismic deficienci­es.”

Some local officials are spooked enough to start the ball rolling. Los Angeles County Supervisor Janice Hahn has proposed a plan to assess all the high-rises in unincorpor­ated L.A. County, which will be discussed at this week’s Board of Supervisor­s meeting.

Koffman of USC has been examining video of the Champlain Towers collapse, and of the condition of the garage beforehand. He suspects well-documented problems with water intrusion and the pool deck will ultimately emerge as the culprits in its collapse. He also expects the tragedy to spark robust discussion, thorough examinatio­n and, likely, change.

“Whenever there’s an incident like this, we learn from it,” he said.
