“Structural Issues” Cause Bay Area Condo Building to Be Evacuated Until Temporary Shoring is Installed

UPDATE AS OF 3/19/26

We spoke with reporter Kevin Nguyen at the SF Standard regarding this property after he reached out to us asking about this property. We were the source that alerted Kevin to the fact that the picture below by  Anna Nevskaya showed failed post tension cables poking out from the building.

Turns out that post tension cables that support the podium deck slab have failed. I saw a review on Google by an owner at the property and knew instantly this building is F’d.

I’ll now predict that the slab can’t be fixed and the building will have to be demolished. What engineer in their right mind would believe that the other cables that aren’t broken are ok and just recommend repairs to the failed cables? No one in their right mind would in my opinion.

Post tension cables have broken in numerous places in one area as seen in this photo taken by Anna Nevskaya (and republished here for public knowledge.) The cause is unknown but is likely related to either damage caused by a massive fire that occurred during the construction, water damage or both.

Instagram Featured Video Stair Rebuild by One Structural/Balcony 1 Shows Multiple Construction Defects Being Installed in Real Time!

“Clowns to the left of me, jokers to the right, here I am, stuck in the middle…”

A recent Insta video posted by One Structural/Balcony 1 reminded me of the lyrics from a 1972 song by Stealers Wheel… And after watching the video several times I wondered why I wasn’t having a stroke over the numerous defects in their work. The video purports to show their expertise in rebuilding a set of stairs and waterproofing them. (The video appears to have been removed from their profile located here https://www.instagram.com/onestructural?igsh=MzRlODBiNWFlZA==)

In the video it showed a timeline of rebuilding a set of stairs. As I watched it play out I screenshot a few pics, see below.

Starting with the framing rebuild, we can see water/fungus damaged stair stringers that weren’t replaced, damaged sheathing on the wall that wasn’t replaced and new wood that looks like my 3 year old nephew installed.

A Recent Home Inspection Shows Why a Seller Provided Home Inspection Report is Essentially Worthless

The other home inspector missed this “little” issue

A recent inspection we performed for a prospective buyer of a condominium in San Luis Obispo demonstrates perfectly, why you as a buyer need to have your own inspections done at your own cost. This particular inspection found many issues that were glossed over as simply needing patching and painting rather than complete replacement of major components such as windows, doors, decks and subflooring under a shower.

The seller had a pre sale inspection done at their expense and provided that report to the prospective buyer. He had questions and doubts about the report and reached out to us after searching for a waterproofing and building consultant.

Our inspection found that many items the other inspector glossed over in his report as needing “patching and painting” or minor repairs were far from the real situation which was that all the doors and windows were past their useable lifespan and needed to be completely replaced. We found dry-rotted framing on decks, open and exposed framing on columns, dry-rot in the substrate below a shower floor which requires the substrate to be replaced due to fungus infestations.

William Leys Waterproofing Consultants LLC Helps Clients Whose Property Has Been Damaged Caused By Construction Defects Recover Financially

Even before William Leys Waterproofing Consultants LLC was formed, President Bill Leys has been assisting clients throughout California recover financial damages from contractors who caused construction defects that led to water intrusion and property damage. As an expert waterproofing consultant serving San Luis Obispo, Santa Barbara, Ventura, Kern and Los Angeles counties, we’ve helped clients recoup hundreds of thousands of dollars in the past few years.

Our expertise in building technology and waterproofing methods, investigative skills and ability to document and report on the problems, the causes and suggested repairs needed have allowed our clients to convince the Contractors State License Board, the contractors at fault and their Bond companies to act. We’ve seen great success with the CSLB investigating complaints, contractors agreeing to repair defective work and have bond and insurance carriers pay on claims made by our clients.

Some recent success stories include helping a client in San Bernardino recover 5k+ in damages caused by faulty deck waterproofing work by a contractor from Palm Springs. Our investigation found that the contractors “expert witness” actually had business ventures with his client, leading to the Judge concluding the contractors witness had implicit bias in favor of his client. In other words, his testimony was rejected by the Court. Our client got a court order that the contractor had to remove a lien on their home and could not collect $5,000 they claimed our client owed.

No blocking between the old and new plywood is a defect that will cause any waterproofing to eventually fail.

Another success story found us assisting a client in Avila Beach whose recent kitchen addition was apparently leaking. Our investigation found windows were leaking from faulty installation, deck flashing that leaked from faulty installation and as a result of our testing and report, the client was able to successfully initiate a claim against the contractors general liability insurance and recover funds to repair their damages. The client made a confidential settlement with the insurance company for well over 6 figures.
