Second story additions in Spring & Klein
The Spring and Klein area grew up fast in the 1970s through the 90s, and a lot of what was built then is a one-story house on a slab — sound, well-located, and too small for the family living in it now. Schools are a big reason people stay — Klein ISD across much of the area, Tomball ISD in Creekside Park, the youngest village of The Woodlands, which shares the 77389 ZIP. For those families, a second story is the way to stay put.
Almost all of 77388 and 77389 is unincorporated Harris County, so there is no city building department to deal with — but that does not mean no paperwork. Harris County requires a permit for all development, and flood history matters here: during Hurricane Harvey, Spring Creek — the line between Harris and Montgomery counties — crested at 111 feet, and homes along the creek corridors flooded. Where a house sits relative to the mapped floodplain shapes what an addition can cost.
BT Grace Homes builds the new level for Houston's humid Climate Zone 2A — airtight and water-tight, with ventilation and dehumidification designed into the HVAC rather than left to leaks. BT Grace Homes frames the new floor above your existing roof and gets it fully dried-in before the old roof comes off, so the house below stays sealed and your family stays home for the build.
What changes if my Spring home is in the floodplain?
In unincorporated Harris County, a development permit is always required, and a lot in the 100-year or 500-year floodplain needs plans from a licensed architect or engineer, an elevation certificate, and a site plan showing the base flood and finished floor elevations. Harris County also notes that substantial improvements may need to bring the whole structure into compliance with current development standards.
That is why the first step on a Spring-area second story is checking the flood map and, where it applies, the improvement-to-value math — before anyone draws a floor plan. If your home is outside the mapped floodplain, the process is much simpler.

Common questions about second story additions in Spring & Klein
Do I need a permit for a second story in unincorporated Spring or Klein?
Yes. Harris County requires a permit for all development in unincorporated areas. If the lot is in the 100-year or 500-year floodplain, the permit also needs drawings by a licensed architect or engineer, an elevation certificate and a site plan with flood elevations.
My Spring home flooded during Harvey. Can I still add a second story?
Often, but the floodplain rules come first. Substantial improvements in Harris County may need to bring the existing house into compliance, which can mean elevation requirements. BT Grace Homes checks the flood map and the numbers before design, so you know whether a second story is practical before spending on plans.
Will adding a second story keep my kids in the same school district?
Yes — you keep your address, so you keep your current school zone, whether that is Klein, Tomball or Spring ISD. Keeping the schools is one of the main reasons Spring-area families choose a second story over moving to a bigger house somewhere else.
