STAMFORD — The city’s biggest builder, Building and Land Technology, and one of its most controversial daughters, Candace Owens, have something in common.

They’ll face off this spring in a civil jury trial in state Superior Court in Stamford. Owens claims her 16th-floor luxury apartment in BLT’s Beacon building — where she lived from October 2015 until January 2017 — was so infested with “mold and/or other contaminants” that she developed more than a dozen ailments.

The 29-year-old conservative commentator, who first made headlines for being bullied and threatened as Stamford High School student, is seeking more than $15,000 from BLT.

BLT, through holding company Three Harbor Point Square, denies Owens’ allegations and counters that she bilked them six months rent — $3,550 a month in the luxury building.

She was responsible for any mold or mildew, BLT attorney Trevor J. Keenan wrote in a counter claim.

BLT did not immediately respond Tuesday to a request for a comment. Owens, reached by phone this week, declined to comment.

“It’s an open case, so I don’t really have the privilege to talk about it,” she said. Her attorney, Jeffrey Lynch, did not immediately respond to a request for comment.

According to Owens’ complaint, filed in July 2017, she learned of an old leak in the apartment in August 2016. Owens claims the leak was caused by BLT’s carelessness and negligence.

BLT “caused or allowed and permitted the water to penetrate” the apartment, according to the complaint, causing the air to become “contaminated and dangerous for use and causing mold to grow.”

BLT failed to resolve the “dangerous condition” and did not clean up the apartment or warn Owens of the situation, the complaint said.

The toxic luxe apartment soon started harming the headline maker’s health.

She came down with 15 ailments, “some or all of which may be permanent in nature,” the complaint said. Her symptoms include wheezing, “an inability to think clearly,” scars requiring laser removal, eczema and “systemic yeast infections.”

Months before Owens filed the lawsuit, she invited a Hearst Connecticut Media Group reporter and photographer into her apartment and home office for a story on her new venture, launching a website to call out online bullies.

The purpose of SocialAutopsy.com was to allow social media users to take screenshots of posts they find offensive and send them to the site, which would collect them into profiles. The website was going to have a search engine, allowing users to type in someone’s name and see if they’ve made offensive comments online.

Owens believed people might be disinclined to post hateful and offensive speech if they could be forever tagged to it.

The site, which was roundly condemned as promoting further discord and the act of “doxing,” or publishing personal information of others online, was never launched, according to New York Magazine. An online fundraising campaign seeking $75,000 to run the site was suspended by Kicksarter after only garnering $4,244.

BLT, in a counter suit, is seeking money for rent it claims Owens didn’t pay and legal costs. The builder said Owens declined to pay rent as she continued to live in the apartment after filing the lawsuit.

Her lease would have ended in February 2017, but she was evicted the previous month after an order from Norwalk Housing Court, according to BLT. State eviction data, however, shows the outcome was a withdraw of action.

BLT said Owens created any mold by leaving windows open with the air conditioning running, failed to tell the landlord about the leak in a timely manner and did not comply with mold and mildew related provisions of her lease.

Jury selection and a trial, originally slated for later this month, has been postponed to May 5.

Owens first made headlines after receiving threatening and racist epithet-filled voicemails while a student at Stamford High. The issue turned scandal when the boy charged in the case was in a car with several other teens — including the then-14-year-old son of former mayor and governor Dannel P. Malloy.

Owens’ family sued the city Board of Education, which later paid $37,500 to settle the case.

Owens made headlines again when she became communications director for Turning Point USA, a conservative group close to President Donald Trump.
