🏗️ What the Inspector Should Have Caught
Licensed home inspectors in California must follow industry standards when evaluating a home's foundation. If your inspector missed any of these issues, you likely have a negligence claim:
🔍 Foundation Cracks
Vertical cracks indicating settling, horizontal cracks suggesting pressure, stair-step cracks in block foundations, and cracks wider than 1/4 inch that indicate structural movement.
📐 Settling & Sinking
Uneven or sloping floors, one side of house lower than the other, doors and windows that stick or won't close, gaps between walls and floor or ceiling.
💧 Water Intrusion
Water stains on basement walls, efflorescence (white mineral deposits), moisture in crawl space, standing water, and drainage problems around foundation.
🧱 Bowing & Leaning Walls
Basement or foundation walls bowing inward from soil pressure, leaning exterior walls, separation of walls from the main structure.
⬆️ Heaving
Upward movement of foundation from expansive soils, frost heave, or hydrostatic pressure—causing floors to bulge and structures to shift upward.
🔗 Post-Tension Cable Issues
For homes with post-tension slab foundations: signs of cable failure, unusual cracking patterns, or evidence of improper tensioning that a competent inspector should flag.
Critical: Get a Structural Engineer Assessment
Foundation issues are complex. Before sending your demand letter, hire a licensed STRUCTURAL ENGINEER (not just another home inspector) to document the damage, determine the cause, and provide repair cost estimates. Their professional opinion is your strongest evidence.
⚖️ California Laws That Protect Home Buyers
Business & Professions Code § 7195-7199 – Home Inspection Law
California home inspectors must meet minimum standards of practice. They must inspect and report on the foundation, including visible cracks, evidence of water intrusion, and structural deficiencies. Negligent inspections create liability for resulting damages.
Civil Code § 896 – Construction Defect Standards
This statute defines functionality standards for residential construction, including foundation requirements. Foundations must not allow water intrusion, must support the structure as designed, and must not cause damage to other building components. Inspectors should identify violations of these standards.
Contractors State License Board (CSLB)
Foundation repair contractors must be licensed. If the original construction was defective, you may also have claims against the builder (within 10 years for foundation issues under Civil Code § 896). Your inspector should have identified construction defects.
Types of Foundation Cracks & Their Significance
| Crack Type | What It Indicates |
|---|---|
| Vertical Cracks | Normal settling if minor; significant settling if wide or numerous |
| Horizontal Cracks | Soil pressure against walls—serious structural concern |
| Stair-Step Cracks | Differential settling—one part of foundation moving differently |
| Diagonal Cracks (45°) | Shear stress from settling or soil movement—structural issue |
| Cracks > 1/4" Wide | Active movement requiring immediate evaluation |
E&O Insurance = Your Recovery Source
Most home inspectors carry Errors & Omissions (E&O) insurance specifically for negligence claims. Foundation claims can be high-dollar, making insurance coverage essential. You're not just going after an individual—there's typically insurance to pay legitimate claims.
💰 What You Can Recover
Foundation repairs are among the most expensive home repairs. California law allows you to recover all damages caused by the inspector's negligence:
- Foundation repair costs — Underpinning, pier installation, slab repair, crack injection, wall stabilization
- Structural repairs — Leveling floors, straightening walls, repairing framing damage
- Water intrusion remediation — Drainage systems, waterproofing, French drains, sump pumps
- Cosmetic repairs — Drywall, paint, flooring, tile damaged by foundation movement
- Temporary housing — If you must vacate during major foundation work
- Diminished property value — Foundation problems can permanently reduce home value even after repairs
- Structural engineer fees — Cost of professional assessment documenting the damage
- Permit and engineering costs — Required for major foundation repairs
Typical Foundation Repair Costs in California
| Repair Type | Typical Cost Range |
|---|---|
| Minor crack repair (epoxy injection) | $500 - $3,000 |
| Moderate repairs (partial underpinning) | $10,000 - $35,000 |
| Major repairs (full underpinning/piers) | $35,000 - $100,000 |
| Severe structural damage (extensive work) | $100,000 - $150,000+ |
| Complete foundation replacement | $150,000 - $250,000+ |

Dear [Inspector Name]:
I am writing to demand compensation for damages resulting from your negligent inspection of the foundation at the property located at [Property Address], performed on [Date].
FACTS:
1. On [Date], I purchased the above property in reliance on your Home Inspection Report, which indicated [what the report said about foundation - e.g., "foundation in serviceable condition" or "no significant structural defects observed"].
2. On [Date you discovered damage], I discovered significant foundation and structural damage that your inspection failed to identify, specifically: [describe damage - e.g., "major horizontal cracking in the basement walls indicating soil pressure, significant settling causing floors to slope 2 inches across 15 feet, and active water intrusion through foundation cracks"].
3. On [Date], I retained [Structural Engineer Name/Company], a licensed structural engineer, to conduct a thorough foundation assessment. Their report (attached) confirms:
• [List findings from structural engineer report]
• The damage exhibits visible warning signs that should have been identified during a competent inspection
• The estimated cost of foundation repairs is $[Amount]
• Additional structural and cosmetic repairs will cost $[Amount]
NEGLIGENCE:
As a licensed home inspector, you owed me a duty to conduct a thorough, competent inspection of the property's foundation in accordance with industry standards and California Business & Professions Code Sections 7195-7199. You breached that duty by:
[Check all that apply and customize:]
• Failing to identify visible foundation cracks that exceeded acceptable tolerances
• Failing to note signs of differential settling (uneven floors, sticking doors/windows)
• Failing to identify evidence of water intrusion through the foundation
• Failing to observe and report bowing or leaning foundation walls
• Failing to recommend a structural engineer evaluation when warning signs were present
• Providing an incomplete or misleading report regarding foundation condition
• Failing to properly inspect accessible crawl space or basement areas
As a direct and proximate result of your negligence, I have incurred the following damages:
DAMAGES:
Foundation Repair (underpinning/piers/stabilization): $[Amount]
Structural Repairs: $[Amount]
Water Intrusion Remediation: $[Amount]
Cosmetic/Interior Repairs: $[Amount]
Structural Engineer Assessment: $[Amount]
Temporary Housing (if applicable): $[Amount]
Diminished Property Value: $[Amount]
[Other documented damages]: $[Amount]
TOTAL DAMAGES: $[Total Amount]
DEMAND:
I hereby demand payment of $[Total Amount] within thirty (30) days of the date of this letter to compensate me for damages caused by your negligent inspection.
Please forward this letter to your Errors & Omissions insurance carrier for processing. If you do not have E&O coverage, you will be personally liable for these damages.
If I do not receive satisfactory response within 30 days, I will pursue all available legal remedies, including filing a complaint with the California Department of Consumer Affairs and commencing civil litigation for professional negligence, in which I will seek not only the above damages but also attorney fees, costs of suit, and any other relief the court deems appropriate.
Please contact me at [Phone/Email] to discuss resolution.

📋 Evidence to Gather Before Sending
- Original home inspection report — The report you relied on when purchasing, showing what was said about the foundation
- Structural engineer report — Professional assessment documenting the damage, cause, and repair requirements
- Floor level survey — Measurements showing how much floors slope or are out of level
- Crack measurements — Document crack widths, lengths, and locations with dated photos
- Photographs over time — If possible, photos showing crack progression or worsening conditions
- Foundation repair estimates — At least 2-3 written estimates from licensed foundation contractors
- Purchase contract & escrow documents — Showing you relied on the inspection
- Seller's Transfer Disclosure Statement — To check if seller knew about prior foundation issues
- Communication with inspector — Any emails, calls, or responses to your concerns
- Permit history — Any previous foundation work permits pulled for the property
Document Before Repairs (If Safe)
If conditions are safe, don't begin major repairs until the inspector (or their insurance) has had a chance to inspect. They may want their own structural engineer to assess damages. However, if the structure is unsafe or damage is worsening, prioritize safety—but document everything thoroughly first.
📅 What Happens After You Send the Letter
Days 1-7: Inspector Receives Letter
They'll likely forward to their E&O insurance carrier. Given the high dollar amounts of foundation claims, expect the insurance company to take this seriously.
Days 7-21: Insurance Investigation
The insurance adjuster will likely want to send their own structural engineer to inspect. Cooperate but have your engineer present if possible. Document everything.
Days 21-30: Response/Negotiation
Insurance typically responds with acceptance, denial, or counter-offer. Foundation claims are often disputed—be prepared for negotiation.
Day 30+: If No Resolution
File complaint with California Department of Consumer Affairs. For claims over $12,500, you'll likely need civil court or an attorney. Foundation cases often justify legal representation given the high damages.
❓ Frequently Asked Questions
Can I sue a foundation inspector for missed structural damage in California?
Yes. Home inspectors are licensed professionals who owe you a duty of care when inspecting a property's foundation. If they negligently missed visible foundation cracks, settling, water intrusion, or other structural defects, you can recover repair costs, diminished value, and related damages. Most carry E&O insurance for these claims.
What are signs of foundation problems an inspector should catch?
Visible signs include: foundation cracks (vertical, horizontal, or stair-step), uneven floors, doors and windows that stick, gaps between walls and ceiling/floor, bowing walls, water stains in basement/crawl space, and separation of exterior structures. A competent inspector should identify and document all visible defects.
Should I hire a structural engineer before sending a demand letter?
Absolutely. A licensed structural engineer's assessment is far more authoritative than another home inspector's opinion. They can document the exact nature of the damage, determine its cause, and provide detailed repair specifications and cost estimates. Their report becomes your key evidence.
What if the inspector says the damage was "hidden"?
Inspectors aren't liable for truly hidden defects. However, foundation problems typically show visible warning signs—uneven floors, cracked drywall, sticking doors. If these signs were present and the inspector failed to note them or recommend further evaluation, they may still be liable. The key is whether a competent inspector would have identified the issue.
How long do I have to file a claim?
For professional negligence, California law generally gives you 2 years from when you discovered (or should have discovered) the damage under CCP 339. The "discovery rule" may extend this for hidden defects. Don't wait—send your demand letter promptly after discovering the problem.
Can I also sue the seller or builder?
Possibly. If the seller knew about foundation issues and didn't disclose them, you may have fraud claims against the seller. For construction defects, you may have claims against the builder for up to 10 years under Civil Code § 896 for foundation issues. Your attorney can help identify all potentially liable parties.
