It’s not unusual for owners to install air conditioning to their homes, especially considering how hot Australian summers can get. However, before installing air conditioning to your property, there are a few things to consider.
Installing air conditioning on common property is generally regarded as an improvement rather than a structural alteration. This type of work is typically treated as a minor renovation or improvement. In most schemes, a fixed air conditioner usually requires a compressor and pipes to be fitted to the exterior of the building, which may require drilling into the wall. As exterior walls are common property, you generally need to get permission from your owners corporation or body corporate before going ahead with an installation.
Before you begin planning to install air conditioning in your scheme, we recommend that you review your building’s by-laws or building rules. These may specify whether air conditioning units are permitted, the type of unit allowed, the location of the condenser, and whether approved installers should be used. By-laws or building rules often include conditions such as matching the unit’s colour and associated pipes to the building’s finishes, complying with noise limits (e.g. maximum decibel levels), and restrictions on installation times or access for tradespeople.
If your building does not have a by-law or building rules for air conditioning, they may need to be introduced. In some cases, council approval may also be required to meet environmental or noise regulations. To determine the most appropriate course of action, check with your strata, owners corporation or body corporate manager or building manager before proceeding.

Once you understand the air conditioning requirements, you may wish to discuss your requirements with a licensed and reputable air conditioning company. We recommend that you provide them with the relevant section of your by-laws or building rules, so they too understand the requirements before installing air conditioning in your owners corporation or body corporate property.
It’s wise to request that they address the following details in their quotation:
When installing air conditioning, it’s essential to make sure the work meets your owners corporation or body corporate’s requirements. Your by-laws or building rules exist to protect owners from poor-quality installations, so ask for all approvals and conditions in writing. If possible, be present during the installation to confirm that it aligns with the agreed-upon specifications.
Keep in mind that an air conditioning unit servicing your lot is generally covered under your personal contents insurance, not the owners corporation or body corporate’s insurance policy.
Installing air conditioning usually involves common property such as external walls or penetrations for pipes, meaning approval from the owners corporation or body corporate is often required. Here are some key points to keep in mind when seeking approval:
To improve your chances of approval, you might include the following in your request:
After approval and once you have an installation date, notify any neighbours who might be affected. Provide at least two weeks’ notice and include:
Your installer should provide you with a dated and signed commissioning certificate upon completion of the job. The owners corporation or body corporate may also request a photo of the completed work to confirm compliance with the approval conditions.
Getting approval from your owners corporation or body corporate before installation helps avoid problems later. Without approval, the committee may ask you to move the unit or remove it entirely.
Installing air conditioning is often treated as a minor renovation when it involves changes to common property, such as external walls or pipe penetrations. You will need to contact the owners corporation, strata committee, or strata managing agent and request permission before starting work.
You should provide:
Approval is usually given by a vote at a strata meeting, and more than 50 per cent of the votes cast in favour of the work is required.
If allowed under a by-law, a strata committee may consider minor renovation applications for air conditioning. If a strata committee refuses to approve the installation, it must give written reasons for the refusal within three months of receiving the request. If the strata committee does not refuse the application within three months, then the application is usually assumed to be approved.
As a lot owner in an owners corporation, you are generally entitled to install air conditioning inside your apartment or unit. However, you typically need to notify your owners corporation if the installation requires a building or planning permit.
Installation also implies keeping the exterior of your lot in good and serviceable repair, and the appearance of the air conditioning unit should not affect the use and enjoyment of the property by other lot owners.
If an owner does not maintain the exterior in good and serviceable repair, an owners corporation can issue a written notice requiring repairs. If the requested repairs are not carried out within 28 days, the owners corporation can generally perform the work without the lot owner’s approval and charge the owner for the cost.
When installing air conditioning, the owner is expected to:
