Katy zoning limits residential structures to 32 feet measured from the highest natural grade under the slab, excluding chimneys, attic ventilators, and plumbing vent stacks from the height calculation.
Katy's zoning ordinance caps residential building height at 32 feet above the highest natural grade beneath the slab. Chimneys, attic ventilators, and plumbing vent stacks are excluded from the measurement. Industrial M-district structures have no maximum height. Height is enforced through the building permit and inspection process administered by the Building Department, and additions or rooftop equipment that push a structure past 32 feet require a variance.
Constructing or modifying a structure exceeding 32 feet without a variance can result in permit denial, mandatory removal of the over-height portion, daily fines through municipal court, and stop-work orders.
