The county can't zone, so it sets no height limit for unincorporated areas—only FEMA flood-elevation rules apply. In the City of Galveston, R-1 homes are capped at 50 feet measured from base flood elevation; the Broadway corridor caps buildings at 3 stories or 45 feet.
Unincorporated Galveston County has no zoning height limit, but coastal flood rules matter: structures must be elevated to or above base flood elevation, and beachfront construction is regulated by Texas GLO dune rules. City codes set heights. The City of Galveston's R-1 district caps building height at 50 feet, measured from base flood elevation—a distinctive coastal benchmark that accounts for required elevation on pilings. Some far-east-island properties have unlimited height. The Broadway Boulevard design corridor limits buildings to 3 stories or 45 feet, whichever is more restrictive. Downtown height-and-density zones allow taller low-, mid-, and high-rise buildings. League City and Texas City set separate limits.
Exceeding a city height limit can void permits, block final inspection, and require redesign, variance, or removal of the over-height portion.
