Carpet conundrum
Question from Arlene updated on 22nd February 2011:
Our expert Jeff Montgomery responded:

Tenants are responsible for leaving the premises reasonably clean and tidy at the end of the tenancy, including carpets. If the tenants have left the property, including the carpet, in a reasonably clean condition, then to require them to have the carpet commercially cleaned would be to hold the tenants to a higher standard than is required by the Residential Tenancies Act 1986 (the Act). Provisions that are inconsistent with the Act are generally unenforceable. Such provisions may also be seen as an attempt to evade the operation of the Act which may be considered a breach.
The Act also prohibits tenants from waiving their rights under the Act. Any clause of a tenancy agreement that removes these rights will not be enforceable, even if the clause is in writing and has been signed by the tenant.
