Flood, insurance and inspections: questions to ask before you buy in Houston
Houston’s weather makes a few extra questions worthwhile before you commit to a home.
Before buying in Houston, read the seller’s disclosure for past flooding, check the address on FEMA and Harris County Flood Control District flood maps, get homeowners and flood insurance quotes before your option period ends, and book a general inspection plus any roof, foundation or HVAC specialists the inspector suggests. Flood insurance through the NFIP usually has a waiting period before it starts, so shop for it early.

Questions worth asking
- Has the property flooded or had water intrusion? Ask for the seller’s disclosure notice and read it closely.
- What do flood maps and local drainage information show for the address?
- What would homeowners and flood insurance cost? Ask an insurance agent for a quote before you are under contract.
- Is a foundation, roof and HVAC inspection worth it? In most cases, yes.

Frequently asked questions
Does a Texas seller have to disclose past flooding?
The TREC Seller’s Disclosure Notice asks about known flooding, water penetration, floodplain location, flood insurance and flood claims. Read it closely and ask questions.
How do I check if a Houston home is in a flood zone?
Search the address on FEMA’s Flood Map Service Center and on the Harris County Flood Control District website. A home outside a mapped flood zone can still flood, so ask about history too.
When should I get an insurance quote?
Before your option period ends. Insurance costs can change what a home really costs you each month.
