Oviedo Flood Zones by Neighborhood
Flood zone decides two things for a buyer in Oviedo: whether a lender will require flood insurance, and roughly what it costs. FEMA maps every parcel into a zone — X (and B/C) is low-to-moderate risk with no mandatory coverage; A-series zones (A, AE, AH, AO) are the Special Flood Hazard Area, the 1%-a-year floodplain, where coverage is mandatory with a federally backed mortgage. This page samples the listing addresses in each neighborhood against the current FEMA layer so you can see the pattern before you fall for a house.
Across 15 Oviedo neighborhoods and 184 listing addresses checked against the FEMA National Flood Hazard Layer, 94% of addresses sit outside the Special Flood Hazard Area (Zone X), 6% are in A-series high-risk zones. 1 neighborhood is majority high-risk; 11 sampled entirely outside the SFHA. In a high-risk zone, flood insurance is required with any federally backed mortgage and Florida’s Citizens policies now require it regardless of zone (all policies by 2027).
Flood is a separate policy from homeowners insurance; for the homeowners side, see the cost of home insurance in Oviedo (county Citizens average, ZIP by ZIP).

How to read this
These are shares of listing addresses we have checked, not parcel counts, and FEMA revises maps; a neighborhood at 0% can still contain a low lot. Always verify the specific address at msc.fema.gov.
