For apartment owners, protecting residents and preserving property value in the event of a major earthquake is essential. A properly designed and executed seismic retrofit improves building safety, reduces potential damage, and helps protect long-term rental income. However, not all retrofit projects deliver the same results. Choosing a qualified and experienced seismic retrofit firm is a critical first step in ensuring your building is prepared when the next earthquake strikes.

Key Factors to Consider When Choosing a Seismic Retrofit Contractor

The seismic retrofit process involves both engineering and construction expertise. To ensure high-quality work, it is crucial to partner with an experienced and reputable company. Here are essential questions to ask when evaluating potential contractors:

  • Are they properly licensed and insured?
  • How many years have they been in business?
  • Do they specialize in seismic retrofits, and how many similar projects have they completed?
  • What do past clients say about their work?
  • Do they have a stable and experienced workforce?
  • How well do they communicate and address concerns?

Understanding the Retrofit Process

The first step in a seismic retrofit is a thorough engineering assessment to evaluate risks specific to your property. Factors such as building type, construction year, soil conditions, and liquefaction risks all play a role in determining the necessary structural improvements. An initial assessment can provide insight into the scope of work required before committing to a contractor.

Once you’ve determined that a retrofit is needed, it’s time to research and select the best contractor for the job.

Due Diligence Before Hiring

Verify Licensing and Insurance

Check the legitimacy of your contractor through official databases:

  • California Contractors State License Board: www.cslb.ca.gov
  • California Architects Board: www.cab.ca.gov
  • State Board for Professional Engineers, Land Surveyors, and Geologists: www.bpelsg.ca.gov

Ensure the company holds proper licensing and has adequate liability and worker’s compensation insurance. This protects you from potential legal and financial liabilities if an accident occurs on the job site.

Review Past Work and References

A reputable contractor should have a proven track record with multiple successful retrofit projects. When evaluating past work, consider:

  • The number of completed projects within the past year.
  • Client testimonials and feedback from other apartment owners.
  • Site visits to inspect the quality of completed projects, including structural work and aesthetic integration.

Additionally, assess the contractor’s ability to manage tenant relations. Ask references:

  • Were tenants displaced during construction?
  • Was parking availability impacted?
  • Was the worksite kept clean and safe?

Ensuring a Smooth and Legally Compliant Process

Confirm Proper Insurance Coverage

Never assume a contractor has adequate insurance—always request documentation. Ensure:

  • Worker’s compensation insurance is active and covers all employees.
  • General liability insurance specifically covers seismic retrofit work.

To verify a contractor’s worker’s compensation status, visit the CSLB website, search for the business name, and review their insurance history. If their status is marked as “exempt,” it could mean they have no employees covered under worker’s compensation—putting you at financial risk in case of injury or accidents.

Protect Your Investment

Selecting the right seismic retrofit contractor is one of the most important decisions you’ll make for your property. Partnering with a reputable company ensures your retrofit is completed efficiently, complies with regulations, and provides lasting structural integrity for your building.
