If you are not aware of the installation date of your swimming pool or spa, a pool installer or SPASA member should be able to provide advice. You may also seek information from Access Canberra who may hold information if a certificate of occupancy was issued for the pool or the pool has been subject to an inspection.
During the transition period homeowners are only expected to disclose information reasonably within their knowledge about the regulated swimming pool to inform potential buyers of work that may be required to undertake to be compliant with the new rules. For example, the date that the house was purchased (with an existing swimming pool or spa), or the date of a renovation which included the swimming pool area.
