How do you know if additions/renovations to a home on the market comply with regulations?
IT depends largely on the specific house and you can’t ever guarantee everything complies with current regulations.
As a start, it’s best to ask the real estate agent to produce documentation and written confirmation that the renovations had council approval, which they should be able to provide.
For the renovations to be given council approval then they would have likely complied with current regulations at the time of construction, offering some level of comfort. But if the renovations are more than seven to 10 years old, councils start to throw away records so won’t be much help.
If you’re concerned, seek professional opinion and have a pre-purchase inspection carried out, which will be able to pick up any significant issues. A qualified engineer also can make sure there are no structural problems and major faults caused by the renovations.
Be aware that the house you’re looking at may not comply with all current regulations. For example, in late 2010 there was a change to the building code, which now stipulates all newly constructed homes must achieve a minimum six-star energy efficiency rating: you’ll be hard-pressed to find a house on the market that complies with this regulation.
