Does EBB “Vet” and Regulate Contractors? Here’s the Truth
San Francisco Bay Area
We hear this a lot:
- “He’s on the EBB contractor list, so he must be good.”
- “If the work was wrong, EBB never would’ve approved it.”
- “EBB trains and enforces these guys, right?”
That’s a very common – and very dangerous – misconception.
The short version:
Being on the EBB contractor list does not mean a contractor has been vetted, trained, or actively policed for quality. It means they passed a free, open‑book quiz and filled out a form. That’s it.
For a broader overview of how these programs actually work, you can also read:

What the EBB Contractor List Actually Means
To get on the Earthquake Brace + Bolt (EBB) “participating contractor” list, a contractor must:
- Hold a valid California license in an appropriate classification
- Complete an online orientation and pass a short, open‑book test
- Agree to follow EBB program rules on paper
There is no specialty seismic license, no hands‑on test, and no field competency evaluation included in that.
We have seen:
- Contractors with very little real crawl‑space retrofit experience on the list
- Contractors who clearly do not understand Plan Set A details on the list
- Contractors who have repeatedly done non‑compliant work on the list
And we have seen no meaningful evidence of contractors being removed from the directory for:
- Failing to comply with Plan Set A
- Regularly missing building code requirements
- Doing obviously sub‑standard work that we’ve later been called to correct
In other words, the list tells you:
“This contractor watched a presentation and passed an open‑book quiz.”
It does not tell you:
“This contractor is good, honest, or is being actively enforced for quality.”
What EBB Does (and Doesn’t) Police
As we cover in our program‑based retrofit articles, EBB’s primary job is to:
- Manage grant money
- Make sure paperwork and photos line up with program rules
- Confirm permits and licenses are in place
They review:
- A small set of pre‑retrofit photos
- A small set of post‑retrofit photos
- Basic permit and contractor info
They do not:
- Crawl under houses and inspect anchors, nails, and connectors
- Re‑engineer or re‑design projects
- Police workmanship beyond what shows up in a few pictures (sometimes not even that)
Their own rules say their photo review is to check general conformance, and that it does not constitute a technical or quality review of the work.
Passing EBB and being on the list means:
- You fit into the program mechanics
- You did enough to satisfy the light review
It does not guarantee the retrofit was:
- Well designed for your specific house
- Properly installed
- Free from cutting corners where cameras don’t see

- 6 Dangerous Mistakes That Make Many “Earthquake Retrofits” Fail When It Matters Most

What We’ve Actually Seen in the Field
We’ve been called under a lot of “EBB approved” houses to perform Seismic Truth Audits™.
What we find is depressingly consistent:
- Patchwork scrap plywood instead of real shear wall panels
- Roofing nails or undersized nails where structural fasteners are required
- Missing or misplaced anchors (long blank stretches; anchors too close to edges)
- Clips only installed near the hatch – where photos are easy – with long unconnected runs elsewhere
- No rational pattern at corners or short wall segments
All from contractors:
- In the EBB directory
- With jobs “approved” by programs and cities
We’ve reported some of the worst patterns. Agencies acknowledge they’re understaffed and that true enforcement is rare unless:
- You first win a lawsuit
What we haven’t seen is any obvious “cleaning” of the contractor list based on workmanship.

Why This Misconception Is So Dangerous
If you truly understand how EBB and city inspections work – light paperwork review, limited time under each house – then a contractor saying:
- “We’re on the EBB list.”
- “EBB approved it.”
- “The inspector signed it off.”
…should not be the end of your decision process.
It should be the beginning of your questions:
- “Can I see detailed before/after photos from other jobs?”
- “Can you show me counts and locations of anchors, panels, and hold‑downs on my house?”
- “Who is actually doing the work and how are they supervised?”
The biggest risk is a false sense of security:
- You think you’re covered because the logo is on the brochure.
- You stop asking questions.
- You stop looking under the house.
Then, when a real earthquake hits, you find out that “approved” and “protected” were two very different things.

So How Should You Choose a Contractor?
Treat the EBB list like a phone book, not a quality filter.
Better filters include:
- Detailed Scopes
- Do they tell you quantities, locations, and hardware types?
- Or just “per code / per Plan Set A”?
- Documentation Habits
- Do they routinely provide full photo logs?
- Or is documentation an afterthought?
- Answers Under Pressure
- Do they welcome questions about insurance, workers’ comp, Plan Set A details, and EBB rules?
- Or get evasive and impatient?
- Willingness to Explain Load Paths
- Can they explain, in plain language, how forces move through your house and how their plan improves that?
- Or do they stay at “we do hundreds of these, trust us”?

How Avant‑Garde Fits In
We are on various program lists because owners need those rebates, and we want them to get any help that’s available.
But:
- We did not build our company around chasing “easy EBB jobs.”
- We do not treat program logos as proof of quality.
- We designed Seismic Truth Audits™ precisely because we’ve seen how thin many “approved” jobs really are.
Our focus is:
- Education – you actually understand what’s under your home
- Prevention – reduce damage, not just “pass inspection”
- Mastery – decades focused on seismic, foundation, and drainage
- Documentation – so you and others can see what was done

Practical Next Steps If You’re In or Considering EBB
If you’re using – or thinking about using – EBB:
- Treat the money as a subsidy, not a design manual.
- Use the contractor list as a starting pool, not a stamp of quality.
- Ask program contractors the same hard questions you’d ask anyone else.
- Consider a Seismic Safety Visit to understand what your house actually needs before you shape the scope around a rebate form.
- If you already did an EBB job and you’re not sure what’s under there, consider a Seismic Truth Audit™ to see where you really stand.
Program participation is paperwork.
Performance is what happens when the ground actually moves.
If you want the second to go well, you can’t rely solely on the first.
