Building Permit Drawing Requirements
Conversion to Habitable use
The primary requirement for a habitable room is to ensure moisture does not enter into the structure through the floor the roof and the walls. The National Construction Code - Building Code of Australia (NCC – BCA) specifies the manner by which this can be achieved and will normally necessitate modifications and additional works to be carried out to the existing patio or enclosure.
Most existing patios and non-habitable enclosures do not achieve many of the requirements. It is usual that major modifications are necessary to achieve the requirements of the NCC - BCA for a room to be used for habitable purposes.
Floor Level Subject to Water Level
Hazardous Substances and Asbestos
Hazardous items around the home can be dangerous to the environment and to people. Please visit the waste disposal page for important safety information.
A patio is a pergola with an impervious roof covering (eg. colourbond or polycarbonate sheeting).
A pergola is an open sided structure used for shading and screening, with a permeable roof cover (e.g. shade cloth, lattice or timber battens). A pergola with an impervious roof covering is considered a patio by the City of Kwinana.
When is a Building Permit required for a Pergola?
Any proposed unenclosed pergola that is more than 20m2 in area and/or is more than 2.4m in height will require a Building Permit
Pools, Spas and Safety Barriers
Under the Building Act 2011, a building permit is required for a swimming pool and an outdoor spa. This includes inflatable and/or portable above-ground pools.
Had enough of your pool? here are some handy hints to follow:
- totally remove your pool if above ground; or
- totally remove your pool and backfill if below ground and obtain a compaction certificate for the backfill; or
- leave pool in, but make two holes (minimum size of 1m x 1m each) one in the deep end and another in the shallow end of the pool.
Once you have done one of the above options, contact the City's Building Department on 9439 0208 to arrange an inspection.
Requirements Specific to Suburbs
A front fence includes a wall, screen, retaining wall or the like located in the front setback area of a property.
When is Council approval required?
A building permit from the City is required if the proposed front fence height exceeds 1200mm in a Residential Zone.
Please note that an application for a building permit application must be submitted:
- if a solid front fence exceeds 1.2m in height; or
- if a solid front fence is more than 750mm in height and is located within 1.5m of any driveway.
It should be noted that a front fence may also be a dividing fence between different properties. In such situations, the Dividing Fences Act 1961 may apply. You may need to discuss with your neighbour regarding your proposed front fence.
The City of Kwinana does not administer the Dividing Fences Act 1961. An online brochure
Retaining Walls - Residential
Retaining walls are sometimes required to facilitate proposed ground levels on a lot.
If the proposed retaining wall is substantial, a building licence will need to be obtained from the City's Building Service prior to construction. In some instances, in addition to a building licence, a development approval may also need to be obtained from the City's Planning Service.
Depending on the extent of the retaining works, a minor retaining wall may sometimes be constructed without the approval of the City.
A shade sail is a piece of permeable fabric that is fixed to timber or metal posts.
When is a Building Permit required for a Shade Sail?
Any proposed shade sail that is more than 10m2 in area and/or is more than 2.4m in height will require a Building Permit
Note: A Building Permit and/or Planning Approval will be required for most proposed outbuilding/s. Please contact Building Services 9439 0472 for more information.
Smoke Alarms - Residential
New regulations came into effect as of the 1 October 2009 that require mains powered smoke alarms to be fitted to homes that are subject to sale, lease or hire.
Storm water/surface water resulting from a storm having an average recurrence interval of 20 years is required to be contained within the subject site. Storm water must be disposed of in a way that avoids the likelihood of damage or nuisance to another property.
Termites occur naturally throughout Australia and there are many species. Only a few species pose a major threat to buildings because they eat wood and other materials containing cellulose plant fibre. If left unchecked, they can destroy both the strength and appearance of timbers in buildings.
Because the termite nest is often beneath the soil surface, entry into a building can go unnoticed as severe structural damage may take a long time to become visible. If termites are discovered on your property there is no need to panic but there is a need for further investigation by a registered pest control operator. The Building Code of Australia stipulates that all new buildings require some form of protection from termite entry.
A rainwater tank does not require a building permit provided that the tank is a small proprietary type of steel or fibre glass tank with a height not more than a standard fence height i.e 1.8m. Indicatively, the tank is less than 5,000 litres capacity. The location of the tank should be in the rear yard of a property and not be visible from the primary or secondary streets.
The base of the tank is to be located directly on the ground or supported by a manufacture designed tank stand not exceeding 300mm in height. For all other situations a building permit would need to be obtained prior to installation.
