Whilst the tenant does not need permission to make changes, the tenant must inform you, as the community housing provider, about the changes prior to them happening. The tenant must also have the security upgrades be installed by a qualified trade person(s).
Any associated costs are the tenant’s responsibility but may be funded under a Safe at Home program. A copy of any settled invoice should be supplied to the landlord. All upgrades should comply with strata by-laws and take into consideration the age and character of the property.
End of the Lease
At the end of the tenancy, you can ask the tenant to restore the rental property to its original condition. Alternatively, if you feel the upgrades add value to the home and you would like to leave them in place you could negotiate to pay an appropriate amount to the exiting tenant.
