How Often Should You Inspect Your Building for Structural Issues?

Knowing how often you should check your building for structural problems is very important for any property owner. The answer depends on several things. Most experts recommend a full structural inspection by a certified engineer every 3 to 5 years.

However, this can change based on factors like the age of your building, its location, the local weather, and how you use the property. Regular inspections help spot small issues before they become serious and expensive, keeping your building safe and in good condition. Acting early is almost always cheaper and safer than waiting for obvious signs of damage.

Different building parts may need to be checked at different times. For example, the roof should be inspected every year, especially after strong storms, because leaks can quickly harm the building’s structure.

Foundations and outside walls often need to be looked at every 3 to 5 years, or sooner if you see problems like cracks or settling. Taking good care of older buildings might mean using expert masonry restoration services to keep your property strong and attractive.

Typical Inspection Frequency for Residential Buildings

If you own a home, having regular structural checks is an important part of maintenance. A full inspection every 3 to 5 years is a good rule, but some parts of your home need more attention.

The foundation, for example, should be checked by a professional at least once a year. This helps find problems early before they turn into big and costly repairs like uneven floors or cracked walls.

Other main parts of your house, like floor joists, supporting walls, and beams, usually need a structural check every 5 years. However, if you see signs such as sloping floors or doors and windows that stick, it’s best to have an engineer look right away.

Also remember, systems like heating, plumbing, and electrical should be checked every year to make sure leaks or other problems aren’t causing hidden structural damage.

Recommended Schedule for Commercial and Multi-Unit Properties

Commercial and multi-unit buildings often have higher traffic and greater stress, so they require more regular checks. For these buildings, a full inspection should happen at least every 3 to 5 years. These inspections help catch problems early and help plan for future maintenance and spending.

Local rules may also require inspections. In places like Florida, older commercial buildings must have Milestone Inspections after 30 years, or 25 years if near the coast. Multi-family buildings are encouraged to get Structural Integrity Reserve Studies (SIRS), which help plan for repairs ahead of time. Meeting these requirements helps keep people safe and protects your investment.

Special Considerations for Older or Historic Structures

Older and historic buildings often last a long time, but they also face special challenges. Materials naturally get weaker over decades, and older repairs may not have been done well. Buildings older than 20 years, especially those near the ocean or in harsh climates, should be checked every 2 to 3 years.

Traditional materials, like old masonry, can wear out in ways modern materials don’t. Inspectors with experience in historic buildings can find warning signs that others might miss, like unusual cracks or small movements in the structure. Preventive care, including masonry restoration, is often needed to keep these buildings safe and valuable.

Compliance with Local Codes and Recertification Requirements

Local building codes and recertification requirements also set how often inspections are needed. These laws, which can be different depending on the area, aim to protect the public. For example, in New Jersey, a new law passed in January 2024 requires regular inspections for some residential buildings to keep them safe.

If you don’t meet these requirements, you could face fines or even be forced to leave the building if it’s unsafe. Commercial and multi-unit buildings often need detailed, professional checks as part of recertification. Check with a professional or your local building department to make sure your building meets all rules and stays safe.

What Factors Affect How Often You Need Structural Inspections?

There is no fixed answer for how often you should inspect your building because it depends on many factors. Knowing what affects inspection timing helps you plan for safety and cost savings. Important aspects to watch include the building’s age, its materials, the weather and climate, construction or repairs done, and risks like floods or earthquakes.

Staying alert to these things helps you spot small problems before they grow, and it helps you make smart decisions about building maintenance.

Building Age and Construction Materials

As buildings get older, their parts naturally wear out-foundations settle, wood may soften or rot, and other materials change over time. Older properties need checks more often to catch problems caused by age.

The material your building is made of also matters. Some materials-like certain bricks or types of wood-get damaged by water or weather more easily. Specialists can advise how well your building materials are lasting and suggest any repairs or upgrades needed to help keep your building strong.

Climate and Environmental Exposure

The local environment plays a big part in how often you need to inspect your building. Homes in places with storms, high winds, big temperature swings, or earthquakes will need more frequent checks. For example, properties in Tennessee feel all four seasons, meaning their foundation and other materials need to be watched closely as weather changes.

Coastal areas face salt and wind that can wear away walls and roofs faster. Even less dramatic weather, like drought followed by heavy rain, can shift the ground and harm your foundation. Schedule extra inspections after big storms or other major events.

Recent Renovations, Damage, or Changes

If you’ve recently remodeled or changed load-bearing walls, or if you’ve had foundation repairs, you should have your property inspected more regularly. Inspections keep track of whether repairs or changes are holding up and help spot any new problems before they get worse.

Minor incidents, like a car bumping the building or flooding, can cause hidden damage that shows up later. An engineer should check your property after any noticeable event, especially before new renovations, to make sure changes don’t put the building at risk.

Location-Specific Hazards: Floods, Earthquakes, and More

Where your building is located also changes how often inspections are needed. In places with earthquakes, you need checks more often, even if big quakes haven’t hit. Regular inspections help find and fix damage from minor tremors over time.

Buildings in flood zones or on hillsides prone to landslides need extra care. Flooding can damage foundations and create mold or rot, which weakens the structure. Even if damage seems minor, a professional checkup can make sure you don’t have hidden problems.

Some insurance companies may even require a special inspection checklist before you can get or renew coverage in risky areas.

When Should You Schedule an Immediate Structural Inspection?

While routine checks help keep your building safe, there are times when you must get an engineer to inspect as soon as possible. Acting quickly can stop problems from getting worse, save money on repairs, and protect people in the building.

If you see any of the signs listed below or experience major events, don’t wait-call a professional right away.

Visible Signs of Structural Damage

If you notice clear signs of damage, it’s time for an immediate inspection. These signs might include:

• Large cracks in the walls or foundation
• Sagging or uneven floors
• Doors or windows that suddenly won’t open or close
• Walls bowing inward or outward
• Water damage or visible mold and rot

These symptoms can show that something is wrong with the main structure of your building. If you spot any of these, contact a structural engineer as soon as you can.

After Severe Weather or Natural Disasters

Severe weather, such as floods, hurricanes, earthquakes, or very strong winds, can cause serious and sometimes hidden damage. Even if everything looks fine on the surface, the structure underneath may be weakened. Key times for an immediate inspection include:

• After heavy storms or flooding
• After an earthquake, no matter how small
• After extremely strong winds

An engineer can spot problems like foundation shifts, roof damage, or water inside walls, helping you fix problems before they grow.

Before Buying, Selling, or Renovating a Property

Always schedule a structural inspection:

• Before you buy a property, to find any hidden problems and help with price negotiations
• Before you sell, to fix issues and boost your property’s value
• Before major renovations, especially if changing walls or adding weight to the structure

Inspections before these big steps can save you from costly mistakes and help with planning safe and successful projects.

In Response to Insurance or Regulatory Requests

Sometimes, insurance companies or local authorities will require you to get a structural inspection, especially in risky areas. If you don’t provide the requested reports, you might lose coverage or have to pay higher prices. Government bodies may also require inspections for building recertifications or in response to safety concerns in your community.

Making sure these checks get done quickly means following the law and keeping your property and anyone inside it safe.
