Climate risk disclosure is becoming a bigger issue in real estate because buyers are no longer evaluating only price, location and condition.
They also need to understand whether a property faces flood, wildfire, wind, heat, storm, insurance or long-term resilience risks. Those risks can affect monthly costs, repairs, financing, resale value and future marketability.
The challenge is that disclosure rules vary widely. There is no single national form that tells every buyer every climate-related risk before closing.
This article is general information, not legal advice. Disclosure laws, forms and duties vary by state.
Key takeaways
- Climate risk disclosure rules vary by state.
- Flood disclosure is one of the most developed areas, but requirements still differ.
- NAR says buyers should talk with insurance agents and mortgage lenders about whether flood insurance is required.
- FEMA’s Flood Map Service Center is the official public source for NFIP flood hazard information.
- CFPB says buyers should add climate risks to the list of factors they consider when deciding on a home.
- Buyers should ask about past damage, insurance claims, coverage availability and mitigation.
- Disclosure forms should not replace independent due diligence.
What climate risk disclosure means
Climate risk disclosure refers to information about hazards that could affect a property because of environmental or climate-related conditions.
That can include:
- flood risk,
- wildfire risk,
- wind or hurricane exposure,
- heat exposure,
- drought,
- stormwater and drainage issues,
- erosion,
- landslide risk,
- insurance availability,
- prior disaster damage,
- and required mitigation.
Some of these risks may appear in state-mandated disclosure forms. Others may not.
Flood disclosure is a major example
Flood risk is one of the clearest examples of uneven disclosure rules.
NAR says it worked with the Legal Research Center to conduct a survey of existing state flood disclosure requirements. NRDC says more than one-third of states have no statutory or regulatory requirement that a seller disclose a property’s flood risks or past flood damages to a buyer, while other states have varying degrees of disclosure requirements.
That patchwork matters. A buyer in one state may receive detailed flood-history information. A buyer in another state may receive very little unless they ask directly.
Official maps are important, but limited
FEMA’s Flood Map Service Center says it is the official public source for flood hazard information produced in support of the NFIP. Buyers can use it to find official flood maps and related flood-risk products.
But official flood maps should not be the only due-diligence tool. A property outside a high-risk flood zone can still flood. CFPB notes that properties not in flood zones can still be at risk and that, on average, 40% of NFIP flood insurance claims occur outside high-risk flood areas.
That means buyers should look beyond a simple yes-or-no flood-zone answer.
Insurance is part of climate risk
Climate risk often shows up through insurance costs and availability.
Treasury/FIO found that homeowners in the highest-risk 20% of ZIP codes paid average homeowners insurance premiums of $2,321 from 2018 to 2022, 82% more than homeowners in the lowest-risk ZIP codes. Treasury also found nonrenewal rates about 80% higher in the highest-risk ZIP codes.
That does not mean every high-risk property is uninsurable. But it means buyers should ask early whether insurance is available, what it costs and whether coverage excludes important risks.
What buyers should ask before closing
Buyers should ask the seller, agent, insurer, lender and relevant public sources:
- Has the property ever flooded?
- Has the property had wildfire, storm, wind or disaster damage?
- Have any insurance claims been filed?
- Has the seller received disaster assistance?
- Is flood insurance required?
- Is homeowners insurance available at normal market rates?
- Are there wind, hail, wildfire or flood exclusions?
- Is the home in a FEMA flood zone?
- Are there local hazard maps?
- Have mitigation improvements been made?
- Are permits available for repairs?
- Are future assessments or mitigation costs likely?
The answers should be reviewed before contingency deadlines expire.
What sellers and agents should understand
Sellers and agents should not guess about disclosure duties.
Because climate-related disclosure laws vary by state, sellers should follow state forms, local rules and legal advice where needed. Agents should avoid giving insurance, engineering or legal opinions outside their expertise.
The safest approach is accuracy and documentation. Known material facts should be handled according to state law, and buyers should be encouraged to complete independent due diligence.
What this means
Climate risk disclosure is moving from a niche issue to a mainstream real estate due-diligence issue.
Buyers should not rely only on listing photos, seller disclosures or mortgage requirements. They should check official maps, ask direct questions, price insurance and consider future costs.
For sellers, climate risk can affect buyer confidence and negotiation. For agents, it creates a need for careful, neutral language and strong referrals to insurance, legal and technical professionals.
The core rule is simple: the earlier climate risk is investigated, the less likely it is to become a closing surprise.
