While a single earthquake inspection provides valuable information about your building's current condition, regular periodic inspections are essential for maintaining long-term seismic safety. Here's why ongoing assessments matter.
Building Materials Deteriorate
Over time, building materials can deteriorate due to age, weather, and use. Connections can loosen, wood can rot, and concrete can crack. Regular inspections catch these issues before they compromise seismic safety.
Building Codes Evolve
Seismic building codes are continuously updated as engineers learn more about earthquake behavior and building performance. Regular inspections ensure your building meets current standards and can identify opportunities for improvements.
Modifications and Additions
If you've made any modifications or additions to your building, these changes can affect its seismic performance. Regular inspections ensure that alterations haven't inadvertently created vulnerabilities.
Previous Repairs May Fail
Even properly executed retrofitting and repairs can deteriorate over time. Periodic inspections verify that previous improvements remain effective and identify any maintenance needs.
Small Seismic Events
Minor earthquakes that you might barely notice can still cause subtle damage that accumulates over time. Regular inspections can detect this damage before it becomes serious.
Insurance Requirements
Some insurance policies require periodic earthquake inspections to maintain coverage or qualify for premium discounts. Regular inspections ensure continued compliance with insurance requirements.
Recommended Inspection Frequency
For most buildings in seismically active areas, we recommend:
- Initial comprehensive inspection
- Follow-up inspection every 5-7 years
- Inspection after any seismic event
- Inspection before major renovations or property transfers
