Are home inspectors responsible for alerting their clients to potential sea level concerns?
The legal responsibility of a buyer’s agent to alert their client to potential long-term environmental hazards can vary by jurisdiction. Whether responsibility lies with an agent for alerting a home buyer to such hazards may be vague. Home inspection is consumer protection and so the decision to alert their client to a potential substantial future cost may be left to individual inspectors, and it may become a moral issue rather than a legal one.
In some areas, such as Ft. Lauderdale, projected sea level rise has caused the city to enact new ordinances requiring seawalls to comply with the new height limits from 3.9 feet to 5 feet when:
- A new seawall is built;
- A seawall needs major repair; or
- A seawall is currently low enough to be overtopped.
Depending on the conditions, seawall work for compliance may cost anywhere from $300 per lineal foot to near $2,000 per lineal for for removal and replacement of an existing wall.
Bear in mind that this is Ft. Lauderdale’s requirements, not Florida state requirements.

The question:
Can a very high potential for rising sea levels to overrun residential waterfront protective structures be considered a material defect?
The answer:
Rising sea levels’ potential to overwhelm residential waterfront protective structures could be considered a material defect under specific conditions, depending on jurisdiction and disclosure laws. Here’s the breakdown:
Key Considerations
- Material Defect Definition:
A material defect is any known issue that significantly impacts property value or decision-making in a transaction[1]. This includes hidden structural flaws (e.g., buried cracks[2]) or environmental hazards (e.g., contamination[1]). - Sea-Level Rise as a Latent Defect:
- If protective structures (e.g., seawalls, dunes) are already compromised or inadequately designed for projected sea-level rise, this could qualify as a material latent defect (non-visible, dangerous, or costly to repair[2]).
- Example: A seawall with hidden erosion undermining its foundation, or permits missing for critical upgrades[2].
- Climate Risk Disclosure:
- While FEMA flood maps don’t currently account for climate change[3], sellers may still need to disclose known risks (e.g., studies showing the property will flood within 30 years[4][3]).
- Coastal properties in areas like the Outer Banks[5] or Nantucket[6], where homes are already collapsing, face heightened scrutiny.
- Legal and Market Trends:
- Courts increasingly recognize climate risks in real estate disputes[7].
- Buyers are suing sellers who fail to disclose flooding or erosion risks, even if the damage hasn’t yet occurred[5][6].
- Insurance retreats and plummeting values in high-risk zones (e.g., Florida, Virginia Beach[3]) signal growing market acknowledgment of these risks.
When Is It a Material Defect?
| Scenario | Likely Classification |
| Existing structural vulnerability to sea-level rise (e.g., eroded seawall) | Material defect (must disclose[1][2]) |
| General regional sea-level projections (no property-specific risk) | Not a defect, but may require advisory |
| Known imminent threat (e.g., city plans to abandon coastal defenses[7]) | Material latent defect (if not obvious[2]) |
Practical Implications
- Sellers: Must disclose studies, inspections, or government notices indicating the property’s protective structures are insufficient for projected sea-level rise[2][3].
- Buyers: Conduct climate-specific due diligence (e.g., NOAA flood mappers[3]) beyond standard inspections.
- Real Estate Professionals: Risk liability if they’re aware of sea-level vulnerabilities but don’t disclose them[2].
In summary, while general climate risks may not always qualify as defects, property-specific vulnerabilities to rising seas increasingly meet the threshold for material disclosure, especially in jurisdictions prioritizing climate resilience
