Are you considering erecting a pergola in your home? If yes, then you know that the very first question that arises is: Do you need a permit for a pergola? Well, there is no definite answer. It really depends on the nature of your construction. If you reside in WA, there are regulations in terms of the Building Act 2011 and Residential Design Codes (R-Codes) that state under what conditions the erection of a pergola is exempt from getting a permit for the construction. You could face penalties, forced demolition, or difficulties in selling your property if you make a mistake. This blog will walk you through the key questions homeowners ask most often about pergola approvals, from what you can build without permission to what it could cost you if you skip the paperwork.
Yes, there are a number of instances where you can begin construction without having to get a pergola permit. But the pergola must meet certain specifications set out in WA building laws.
Here is what typically determines exempt status:
Get in touch with a local handyman to ensure that your pergola gets installed following all the rules and regulations.
One important thing to understand is that there might be specific restrictions set by local councils. For instance, the rules and regulations for setting up a pergola in Perth might not be the same as those in other areas. Always remember to check local council regulations based on specific R-Codes before beginning your pergola project.
The size is the first thing to consider when deciding if you will need a pergola building permit for it. The standard rule for Western Australia is that any ancillary structure, including open pergolas, will be able to go through construction without a permit if its floor space is below 10 square metres for a freestanding structure. But this limit changes according to the structure’s type and classification. Here are the other important factors:
Height is also as crucial as floor space. The structure should not be more than 2.4m in height to qualify for exemption. If your outdoor pergola involves elevated posts or higher roof levels, you will certainly end up requiring permits. This is a common problem that residents face when they are looking to create a spacious outdoor entertainment area with high roofs for ventilation. Consult local carpenters to build a pergola that meets all compliance requirements.
Your pergola needs to adhere to the required distances from the side, back, and front boundaries. The overall recommendation in Western Australia is that you need to have a setback of at least 900 mm to 1 m from the boundary lines. There are also setback requirements based on your council area and R-Code zoning.
Pergola builders must also keep roof drainage in mind. Your pergola’s roof must never drain into an adjacent property. The construction of such a structure in proximity to a boundary or with improper drainage could easily lead to a planning referral.
If you own a strata-titled property or a property listed under the Heritage Register in areas like Subiaco or Cottesloe, you may need more than a building permit for pergola in WA. The owners of strata-titled properties must get written permission from their respective strata company, irrespective of whether council permits are necessary or not, for putting up an outdoor structure. Heritage-listed properties may face additional design constraints to preserve the character of the streetscape.
Building without the required approvals is a breach of the Building Act 2011, and the consequences can be serious. You could face enforcement action from your local council, financial penalties, and be required to modify or demolish the structure at your own cost.
Specific risks include:
The cost of removal and fines combined will almost always exceed what you would have spent on getting the permit correctly from the start. Always get the required permissions and hire pergolas installer in Perth and other regions across Western Australia to go ahead with the project in the right way.
The pergola permit cost in Australia is usually a percentage of the total estimated value of the construction work. Below is a table that will give you an insight into the cost of having your pergola approved and constructed in WA.
| Cost Item | Estimated Range |
| Council building permit fee | Minimum fee $110 |
| Building surveyor or certifier fee | $290 – $890 |
| Basic treated pine pergola (supply and install) | $5,000-$10,000 |
| Mid-range hardwood or steel pergola | $10,000-$18,000 |
| Large custom pergola with added features | $12,000 – $25,000+ |
A few things to keep in mind:
Your costs will also vary depending on the trending pergola designs in WA that you are choosing. Complicated designs might increase labour and material costs.
An open pergola that fits into size and height requirements may not need a permit for most WA homeowners. However, there might be cases where something that does not require permission at the state level will still require local council approval. Failing to get the required approval may result in fines, demolition orders, and difficulties while selling the property.
Before purchasing materials or booking a builder, take five minutes to check with your local council or speak to a licensed building surveyor. That conversation could save you a significant amount of money and stress down the track.
