Remodeling in Houston

Houston grew in waves of slab-on-grade houses: 43%¹ of Harris County homes were built from 1970 through 1999, from inner-loop brick ranches out to the master-planned suburbs. The city permits its own remodels and enforces strict floodplain rules, while Harris County handles the unincorporated areas around it.
