🏠 What Is the FEMA 50% Rule?
If your home is in a flood zone, this is one of the most important rules to understand before starting a major remodel.
The FEMA 50% Rule generally states that if the cost of repairs, renovations, or improvements equals or exceeds 50% of your home’s assessed structure value, the property may be required to meet current floodplain regulations.
This could mean additional requirements such as:
✔ Elevation of the structure
✔ Flood compliance upgrades
✔ Additional construction costs
Many homeowners are surprised to learn the calculation is often based on the structure’s assessed value—not the land value or market value.
Understanding these requirements before designing a project can help avoid costly surprises during permitting.
At Mumford Coastal Construction, we help homeowners navigate flood-zone requirements, permitting, renovations, and additions throughout Sarasota and the surrounding coastal communities.
