Chicago CBS 2 reported on the defects, the video is above.

From the CBS 2 report:

"Two weeks after moving in, we had very serious problems heating our house,” says Lisa Sromek.

And a maddening accumulation of snow and frost inside windows.

“Wouldn’t you be mad?” Edgar Bernal says. “You buy a home in Chicago, you’re supposed to be able to heat it.”

Five experts hired by the condo building association and Bernal for their lawsuit believe the furnace and ductwork that was installed was too small.

Reports also said there was “substantially inadequate insulation,” and the fresh-air intake duct on the roof was installed just inches from exhausts. That could have allowed noxious gases like carbon monoxide to be sucked back into the condo living space.

“It’s a major safety hazard. It’s a significant code violation,” says private home inspector Tom Corbett. He was hired to do an inspection after the condo owners discovered problems. “It violated public health practices and procedures.”

After Bernal complained to the city, it filed a court case citing the builder for “dangerous and unsafe conditions,” including that fresh air duct, which has now been moved 15 feet away as required by code.

“There are still substantial defects in the building,” says attorney Kevin Sterling, who is representing the condo association.

In August 2018, the City of Chicago suspended Noah Properties real estate developer’s license over shoddy wiring that was installed by an unlicensed electrician at four of its newly-built homes. From an article in The Real Deal:

A notice from the Chicago Department of Buildings dated Aug. 17 told Noah principal Bart Przyjemski and a contractor with A.L.L. Builders that an inspection earlier this month found a “hazardous” temporary electrical system behind a new house in the 6500 block of West Dickens Avenue. An “exposed live electrical cable was looped from building to building” to illegally connect power to three other houses in the Belmont-Cragin neighborhood, the document continued.

City buildings officials issued a stop work order on the houses, cut off their electrical service and ordered occupants to vacate the homes.

Buildings department records show a permit was issued for electrical wiring at the Dickens Avenue house on Aug. 10, four days after the inspector was said to have visited.

The suspension is set to take effect Monday, though the developer has until then to request a hearing with the buildings department to contest the it.

Tyler Manic, an attorney representing Noah Properties, wrote in an email that the “matters raised in the notice have been resolved,” but did not specify which violations, or whether the suspension was overturned.

A city official said that a partial occupancy permit has been issued for one of the four buildings, but violations remain on all four properties.
