Flood risk in Maryland isn’t limited to the Eastern Shore. Tidal flooding reaches parts of Annapolis, Baltimore County’s waterfront, and the Bay shoreline, while creeks and rivers flood in places like Ellicott City and western Maryland valleys. If your house sits in a mapped flood zone, or has taken on water before, it affects who can buy it, what they’ll pay, and what you need to tell them. Handling a flood zone address on a Dundalk house?

I’m Evan Weissman. I buy houses across Maryland, including some with flood history. This article covers the maps, the insurance question, and a new state disclosure law that sellers should know about.
Finding out whether you’re in a flood zone
FEMA’s flood maps are the official starting point. You can look up your address on the FEMA Flood Map Service Center. The Maryland Department of the Environment also runs a Maryland flood map site that works with FEMA’s updated digital maps.
The term you’ll hear most is special flood hazard area. Those are zones FEMA maps as having a 1% annual chance of flooding, often labeled with letters starting with A or V. Areas outside those zones can still flood. They just carry lower mapped risk.
Why buyers care so much
If a buyer uses a federally backed mortgage on a house in a special flood hazard area, the lender generally requires flood insurance. That adds a yearly cost that some buyers don’t expect, and it can change what they can afford. FEMA’s FloodSmart site explains how National Flood Insurance Program policies work and why it’s worth getting a quote early.
A few things help a buyer here:
- An elevation certificate. It documents the elevation of the house relative to expected flood levels and can affect insurance pricing. If you have one, find it.
- Your current policy. An existing flood insurance policy may be transferable to a buyer. Ask your agent.
- Records of mitigation work. Raised utilities, flood vents, a sump pump, or regrading can all matter to a buyer and an insurer.
Maryland’s new flood risk disclosure law
In 2026 the General Assembly passed House Bill 200, which the governor signed as Chapter 776. According to the Department of Legislative Services fiscal note, starting July 1, 2027, sellers of most homes with four or fewer units must give buyers a completed flood risk disclosure form before the contract is signed, along with a FEMA elevation certificate if one is available.
MDE has to publish the form by June 1, 2027. The fiscal note says it will ask, at minimum, about:
- Whether the property is wholly or partly in a special or moderate-risk flood hazard area
- Any known past federal disaster assistance for flooding
- Whether federal rules require the owner to carry flood insurance
- Whether the seller has flood insurance now and an elevation certificate
- Any known flood insurance claims, including through the National Flood Insurance Program
- Any known flood damage, water seepage, or pooled water from natural events
The law lists exceptions, including certain new homes, foreclosure and tax sales, sales by lenders after foreclosure, and transfers by a fiduciary administering an estate, guardianship, or trust. Since the form doesn’t exist yet, check with your agent or attorney for the current requirements when you sell.
What you should disclose today
Even before that law kicks in, Maryland sellers can’t hide known problems. If you know about flood damage or water intrusion that a buyer wouldn’t find on a reasonable inspection, Maryland’s disclosure rules on latent defects can apply whether you use the disclosure or disclaimer form. My articles on latent defects and the disclosure vs. disclaimer statement explain both.
Waterfront homes also carry the Critical Area notice in most contracts. See the Eastern Shore and Critical Area basics.
After a flood, before a sale
If the house has flooded recently, deal with the water and the claim first. Drying out, removing damaged materials, and checking for mold all matter, both for the house and for disclosure. My articles on storm damage and water damage and mold cover the steps.
Pricing a flood-zone house
Flood zone houses still sell. Price depends on how often the house actually floods, the insurance cost, the condition after any past events, and how much buyers in that area value the location, especially waterfront. A house that’s in a mapped zone but has never taken on water is a very different sale from one that floods every few years.
Listing vs. selling directly
A well-kept flood-zone house with a reasonable insurance quote often does fine on the open market. A house with repeated flooding, an open claim, or major water damage narrows the pool of financed buyers. That’s where a direct sale to a buyer like me can make sense. My as-is selling page explains how I approach those houses.
How do I know if my Maryland house is in a flood zone?
Look up your address on FEMA’s Flood Map Service Center or MDE’s Maryland flood map site.
Does Maryland require sellers to disclose flood risk?
Starting July 1, 2027, under the 2026 law, most residential sellers must give buyers a flood risk disclosure form before the contract. Known latent defects must already be disclosed.
Will a buyer need flood insurance?
If they use a federally backed mortgage on a house in a special flood hazard area, the lender generally requires it.
Can I transfer my flood insurance policy to the buyer?
Often, yes. Ask your insurance agent how a transfer works for your policy.
