Minimum heights for residential rooms and spaces – What are the rules and when should I be concerned?

      By Renee Lovelady Tomas

      Let us set the scene.

      Mary has decided to buy an investment property. It is a Queenslander that has been raised, it contains 3 bedrooms upstairs, one below as well as a large rumpus area. Mary has done her sums and she can get a nice return on this house if she rents it out. Mary’s building inspector takes a look at the ground level of the property and measures the distance between the floor and the ceiling. Mary wonders why the inspector does this…

      Why measure

      A room or space must be of a height that does not unduly interfere with its intended function. The objective is to safeguard the occupants from injury or loss of amenity caused by inadequate height of a room or space. 


      The rules

      The National Construction Code 2016 Building Code of Australia – Volume Two (Class 1 and Class 10 Buildings) is the place to look.

      Clause 3.8.2.1 sets out the acceptable construction practice for heights of rooms and other spaces. The definition of habitable room is:

      Habitable room means a room used for normal domestic activities, and—

      (a) includes a bedroom, living room, lounge room, music room, television room, kitchen, dining room, sewing room, study, playroom, family room, home theatre and sunroom; but

      (b) excludes a bathroom, laundry, water closet, pantry, walk-in wardrobe, corridor, hallway, lobby, photographic darkroom, clothes-drying room, and other spaces of a specialised nature occupied neither frequently nor for extended periods.


      Legal heights

       


      When should I be concerned?

      When the rooms or spaces do not meet the minimum height standards.

       

      Potential problems with purchasing a house with rooms that do not meet the minimum height standards

      The property owner may be left with:

      • A room or space that will not be classed as intended and will not be able to be used as intended;
      • (In certain situations) the Council taking action requiring the property owner to rectify the room heights to conform with the Building Code of Australia;
      • An insurance issue – potentially impacting a claim.

       

      We suggest that, when purchasing a property, you ask your building inspector to consider whether the rooms achieve the minimum heights, particularly in relation to homes that have been raised, extended or renovated.
