A Calgary family was forced out of their Roxboro home in 2013 because of the floods and is now facing a serious water problem in their new home.

Toni Steer sold the family home in the flood zone and moved into a duplex in Bridgeland to escape the water problems.

At first glance the new home looks fine but Steer says the whole thing now needs an overhaul.

The family moved into the home on April 30th and after a couple of rain storms they noticed that the windows were leaking and water was seeping into the basement.

They hired a reputable engineering company to take a look at the building and a number of issues were uncovered.

The family is now on the hook for about $500,000 in repairs and says the city should be held accountable for the damages.

The engineering report found deficiencies in the basement that violate the Alberta Building Code.

The report revealed that the foundation in the front of the home was not damp proofed, which is a thin layer of coating on the basement wall that prevents moisture from seeping in.

According to the city, it's the minimum requirement needed for the building to meet code and something that must be done before a building goes on the market for sale and should have been done by a city inspector.

CTV News obtained a document from the city that shows that on November 28, 2012, it was indicated that damp proofing was required and on the very next day, there were orders to backfill, which could mean a city inspector approved the building and that it met standards.

CTV spoke to Williams Engineering about the report and an engineer said they would have to start from scratch to fix the home.

"It just concerns me that the city, who is tasked with the responsibility with protecting its citizens, would put us in this position,” said Toni Steer. "I don't know how we're going to manage it either financially, mentally or physically it's just devastating”

The city sent a statement to CTV News saying it cannot comment specifically on this case as it's under investigation but says it is working with the family and that because the builder purchased the building permits in 2012, the house falls under the old home warranty act which only covers up to $30,000.

The family says it has started a petition against the city to hold it accountable.
