Earthquake Safety Audit™
San Francisco Bay Area
For Bay Area homeowners who have never had retrofit work done and want a clear, honest picture of how their home will perform in a major earthquake.
Most people have a vague sense their home “might not do great” in a big quake. They’ve seen news clips, heard about cripple walls and foundation bolts, maybe even gotten a scary mailer. But they don’t actually know:
- What would likely fail first
- How bad the damage might be
- What to fix, in what order, for their specific home
That’s what the Earthquake Safety Audit™ is for.
If you want to warm up before an on‑site visit, you can also read some of our cornerstone articles on seismic planning and retrofit quality in the Bay Area:

What the Earthquake Safety Audit™ Is
The Earthquake Safety Audit™ is a whole‑home seismic risk assessment for single‑family homes and small residential buildings that have never had proper retrofit work done.
Our goal is simple: give you a clear, prioritized plan so you can decide, like an adult, what to do and when.
After the audit, you’ll understand:
- How your home is likely to perform in a big earthquake
- What should be earthquake‑retrofitted, and in what order
- Realistic cost ranges for each option, based on current codes and real construction, not marketing talk
No scare tactics, no “limited time” deals, no fake discounts.
Just the truth about your home and a roadmap.
If you want to understand how this fits into the bigger structural picture (load paths from roof to soil), our guide Beyond Foundation Bolts: The California Seismic Load Path Guide for Bay Area Homes is a good companion:

What We Look At
During an Earthquake Safety Audit™, we typically:
Walk the exterior and site
- Foundation type and condition
- Slopes, retaining walls, obvious soil or drainage issues
Evaluate the crawl space and structural framing
- Cripple walls (presence, height, bracing or lack of it)
- Anchor bolts, hold‑downs, sill plates
- Posts, beams, and connections that actually carry your home
Check key interior signs
- Cracks, door and window behavior, floor levelness that might indicate movement
We compare what we see to current best practice and code for Bay Area earthquakes, not just “what passed inspection 50 years ago.”

What You Get: Three Concrete Deliverables
1. Whole‑home structural check
You get a field‑tested assessment of the parts of your home that matter most in an earthquake:
- Foundation and footings
- Crawl space walls and framing
- Floor‑to‑wall and roof‑to‑wall connections
- Any obvious previous “retrofits” that don’t actually meet modern standards
This is not a generic home inspection; it’s focused on earthquake performance.
For deeper reading on foundation and structural evaluations (especially if you’re buying or selling), see our Foundation, Structural & Drainage Risk Evaluation – Bay Area:

2. Red, Yellow, Green action plan
We turn the findings into a simple, color‑coded plan:
- Red: Must‑fix items to avoid major damage or collapse
- Yellow: Smart upgrades that significantly reduce risk when budget allows
- Green: Areas that are effectively safe as‑is
We also give you recommended sequencing, so you know what to do first if you can’t do everything at once.
If you’re trying to decide how far to go, this pairs well with:
- How to Set Earthquake Performance Goals

3. Real‑world cost options
For each red and yellow item, we outline:
- What a code‑correct repair or retrofit actually entails
- Reasonable cost ranges in today’s Bay Area market
- Where phasing makes sense (do this now, that later)
The goal is that you’re not vulnerable to the “cheap, lowest‑bid retrofit” that only looks good on paper. You know what proper work should include before you talk to any contractor, including us.
If you’re also concerned about water and soils (which directly affect foundation and retrofit performance), these pieces are good follow‑ups:

Who This Is (and Isn’t) For
The Earthquake Safety Audit™ is ideal if:
- You’ve never had seismic retrofit work done on the home
- You’re buying or recently bought and want a baseline
- You’re planning to stay 5+ years and want to invest smart, not guess
It’s not the right fit if:
- You have a multi‑unit soft‑story building under a city mandate (you likely need a soft‑story–specific evaluation)
- You’ve already had significant retrofit work and want to know if it was done right (that’s closer to a focused Seismic Truth Audit™ or our Existing Seismic Retrofit Evaluation)

How the Process Works
- Schedule the audit
We confirm your address, year built, basic layout, and any known issues. - On‑site visit
We perform the assessment (exterior, interior indicators, crawl space if accessible).
You’re welcome to walk with us and ask questions. - Written summary & plan
You receive a clear, plain‑English summary with:- Key findings
- Red/Yellow/Green priorities
- Suggested order of work
- Cost ranges for each major item
- Review call (optional but recommended)
We walk through the plan with you, answer questions, and talk through options.
If you want, we can also quote specific scopes and phases.
By the end, you’ll know exactly where your home stands and what it would take to make it much more resilient in the next big earthquake.
If you want clarity instead of anxiety, the next step is simple: schedule an Earthquake Safety Audit™, let us crawl the places you don’t want to go, and we’ll hand you a prioritized, honest plan for your home.
