Houston-Specific Considerations

● Building Codes: Local codes may influence or limit your foundation options.
● Lot Topography: Your lot's slope and soil makeup could make one foundation type more suitable.
● Resale Value: While both types are common, in some Houston neighborhoods, there might be a preference that impacts home value.
