Crosby, Texas
Design and permit drawings in Crosby
Near the San Jacinto River, Crosby has room to build: homes on acreage, barndominiums, shops and barns. We design them and prepare the drawings for Harris County.

Permits in Crosby
Crosby is unincorporated, so Harris County's Office of the County Engineer handles permits. New homes on septic go through the county's residential construction and septic permit, which needs a site evaluation by an engineer or registered site evaluator, a septic design site plan and, for lots outside a recorded subdivision, a survey; the county lists about 30 business days to process it. Work in the floodplain needs a floodplain development permit and a finished-floor elevation certificate after construction.
