A building defects inspection is crucial for maintaining the safety, structural integrity, and longevity of a property. Depending on the type of building, its age, and other environmental factors, the frequency of these inspections can vary. It is important to conduct regular checks to detect any issues early, ensuring that repairs are made before they become costly or dangerous.

Below, we will look at the ideal frequency of building defects inspections for various property types, helping you make an informed decision on when your property should undergo such an inspection. Click this website link.
Residential Properties
For typical residential properties, it is recommended to have a building defects inspection every 2 to 5 years. This timeframe allows for regular checks to ensure the property remains in good condition and free of any potential defects that could cause major issues.
- Properties older than 20 years may need more frequent inspections, typically every 1 to 3 years.
- Homes located in areas with extreme weather conditions or prone to natural disasters, such as floods or cyclones, may need inspections annually or bi-annually.
- Newer homes generally require less frequent inspections, but they should still be checked every few years to ensure everything is functioning as it should.
Commercial Properties
Commercial properties experience higher traffic, and increased usage, and often have complex systems that require regular inspections. Therefore, it’s advisable to conduct building defects inspections every 1 to 2 years for these types of buildings.
- Properties used for business operations, especially those in high-traffic areas, should be checked annually to prevent potential hazards.
- Commercial properties in industrial or high-risk zones should also be inspected more often to ensure structural integrity and safety standards are met.
Industrial Properties
Industrial properties, such as factories, warehouses, or manufacturing plants, generally require more frequent inspections due to their heavy usage, machinery, and potential for wear and tear on infrastructure. For these properties, an inspection once a year is typically recommended.
- High-use areas with large machines or high-risk environments may require inspections more than once a year.
- Regular checks on electrical systems, safety equipment, and structural components are critical to prevent costly repairs and accidents.
Factors Affecting How Often You Should Have A Building Defects Inspection
The frequency of building defect inspections can depend on several factors. These factors take into account the specific needs and conditions of your building, which in turn affect how often an inspection is necessary. The more you understand the factors that influence inspection schedules, the better you can plan for maintaining your property.
Age Of The Building
The age of a building is one of the most significant factors in determining how often you should schedule a defects inspection. Older buildings are more likely to have issues that require attention due to the natural degradation of materials and systems over time.
- Buildings over 30 years old should be inspected more frequently, potentially every 1 to 2 years.
- Properties built within the last 10 years may not need inspections as often but should still be assessed every 3 to 5 years to catch any potential issues before they become serious.
Location And Environmental Factors
The environment in which a building is located can greatly influence the frequency of inspections. Areas with extreme weather conditions or specific risks such as bushfires, flooding, or saltwater exposure require more regular checks.
- Buildings in flood-prone areas should be inspected annually to ensure no hidden water damage or structural weaknesses.
- Properties near the ocean or in humid climates may experience accelerated wear due to corrosion from salt or moisture, requiring inspections more frequently (every 1 to 2 years).
- Properties in bushfire-prone zones should be inspected more often to ensure structural components are protected from fire hazards, especially after an event or season of high risk.
Type Of Building
Different types of buildings have varying needs when it comes to inspections. Commercial and industrial properties often face more wear and tear due to high traffic, machinery, and specialised systems.
- Residential properties generally need inspections every 2 to 5 years, depending on their age and location.
- Commercial buildings typically require inspections every 1 to 2 years due to higher foot traffic and complex systems such as HVAC, plumbing, and electrical infrastructure.
- Industrial properties have the highest inspection frequency requirements, with checks needed at least once a year, especially for high-risk facilities.
Recent Renovations Or Repairs
If any major renovations or repairs have been made to the building, it is essential to inspect the building soon after work is completed to ensure that no defects were overlooked during the process. A follow-up inspection within 12 months is advisable to address any emerging issues.
- Newly renovated homes or buildings should undergo an inspection within the first year to check for defects in the newly installed systems, materials, and structural components.
- Large repairs such as foundation or roof repairs should also be followed up with an inspection within 6 months to ensure everything is still in good condition.
Usage And Foot Traffic
How a building is used and how often it is occupied can significantly impact its condition. Buildings with heavy foot traffic, such as commercial properties or buildings that host large events, are at a higher risk of developing defects sooner.
- High-traffic buildings, such as shopping centres or office blocks, require inspections more frequently, possibly every year.
- Low-traffic homes can typically be inspected less frequently, at intervals of 2 to 5 years.
Building Materials And Construction
The materials used in the construction of the building and the type of construction also influence the inspection schedule. Some materials, such as timber or steel, are more prone to specific issues like rot or corrosion, requiring more frequent checks.
- Timber-framed buildings may need more regular inspections due to the risk of termites and moisture-related damage. Inspections every 2 years would be suitable for such properties.
- Steel-framed buildings, while durable, may still experience issues like rust or structural settling, requiring inspections every 3 to 5 years.
Conclusion
Determining how often to have a building defects inspection depends on multiple factors, including the type of building, its age, location, and usage. Residential properties generally require inspections every 2 to 5 years, while commercial and industrial buildings need more frequent checks. Factors like environmental conditions, recent repairs, and building materials will influence the appropriate frequency for your building.
Regular inspections are key to maintaining the safety, integrity, and value of your property. They ensure that potential defects are addressed before they escalate into more costly problems. Whether you’re managing a residential home, a commercial office, or an industrial facility, scheduling the right frequency of inspections is crucial for maintaining your property’s condition.
Frequently Asked Questions
How Long Does A Building Defects Inspection Take?
The duration of a building defects inspection can vary depending on the size of the property and the scope of the inspection. On average, a residential inspection may take between 2 to 4 hours, while larger commercial or industrial properties may take longer.
What Should I Do If Defects Are Found?
If defects are found during an inspection, it’s important to address them as soon as possible. Minor issues can often be repaired relatively easily, but more significant problems, such as structural damage, may require professional remediation. It’s recommended to consult with specialists to get a proper repair plan.
Can I Conduct A Building Defects Inspection Myself?
While homeowners can perform basic visual inspections, hiring a professional building inspector for a thorough evaluation is always best. Professional inspectors have the experience and tools to identify defects that may not be immediately visible to the untrained eye.
