Garage Conversions


When a garage is constructed, it does not have to meet the same requirements as a home under the Building Code and are therefore not suitable for habitable purposes i.e. non-habitable.

The conversion of a non-habitable space to a habitable space is considered an ‘alteration to an existing building’ rather than a ‘change of use’. The council requires that converted non-habitable spaces comply with the Building Code wherever possible to ensure that the homeowners live in a safe and healthy building.



A Garage Conversion is a good option if you want to add more living space to your home without extending the footprint of the house. However, there are a few council requirements for the conversion, for example,

  • Insulation, building wraps and internal linings are installed. This may require the removal removing of the external cladding so that insulation and building wrap can be installed.
  • Damp proof membranes are in place. This relates to the concrete slab. Typically membranes are placed between the ground and concrete to prevent moisture migrating into the building. Where a membrane has not been placed a topping or surface coating maybe required to protect the internal environment.
  • Providing adequate light and ventilation.
  • If a bathroom is to be built there must be adequate provision for the disposal of internal moisture i.e. steam from showers.
  • Floor, wall and ceiling surfaces are to be sealed, painted or covered.
  • Converting a non-habitable to habitable space usually needs a building consent under the Building Act.


If you have a suitable property that lends itself to a garage conversion, a set of existing floor plans, or just want to be involved in each step of your renovation design, then you should consider using the services of a renovation company such as Style Plus Renovations.
