Understanding the FEMA 50% Rule
The 50% Rule (Substantial Improvement) states that if the cost of improvements equals or exceeds 50% of the building's market value, the entire structure must be brought into compliance with current flood regulations.
The Formula:
Improvement Cost ÷ Market Value = Substantial Improvement %
If ≥ 50%, full compliance required (typically elevation to BFE)
What Counts as Improvement?
- Additions and expansions
- Kitchen and bath remodels
- New roofing
- HVAC replacement
- Electrical upgrades
- Structural repairs
What's Excluded?
- Landscaping and fencing
- Detached structures
- Plans and permits (sometimes)
- Furniture and appliances
- Code-required safety upgrades
- Flood damage repairs (may vary)
