What To Know Before You Build In River Oaks
- Deed restrictions and the property owners' association govern setbacks, height and architectural character
- Mature trees along streets and lots often shape the footprint
- Check the lot's floodplain status; parts of the area sit near Buffalo Bayou
- Plan early for review timelines alongside City of Houston permitting
Floodplain And Zoning
Houston has no traditional zoning, so deed restrictions and local ordinances decide what can be built on each lot. Inside the City of Houston, new homes in the 100-year and 500-year floodplains must be elevated two feet above the 500-year floodplain elevation; confirm your lot's flood zone on FEMA's map before you buy. Use our Lot Check tool to open the official FEMA, Harris County and HCAD records for any address.
