Second story additions in Conroe (77384 & 77385)
The 77384 and 77385 ZIPs carry a Conroe mailing address but cover a patchwork: The Woodlands' College Park village and part of Alden Bridge, neighborhoods inside City of Conroe limits, and areas east of I-45 such as Imperial Oaks and Harper's Preserve, where the exact address decides who permits the work. Imperial Oaks is typical of the area's established stock — mostly brick homes with a median build year around 2000, zoned to Conroe ISD.
Homes from that era are now at the age where families have outgrown them but have no interest in leaving the neighborhood. On a one-story house, a second story adds two or three bedrooms, a bath or a game room above the existing house, keeps the yard, and keeps the kids in the same schools.
BT Grace Homes builds the new level as a high-performance assembly for Houston's humid Climate Zone 2A — airtight, water-tight, with fresh air and dehumidification designed in. 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.
Is my 77384 or 77385 home in Conroe city limits?
Check before you plan. The City of Conroe has annexed land steadily, so two homes with the same ZIP can fall under different rules. Inside city limits, the City of Conroe Building Inspections and Permits division issues the permit and inspects the work. Outside, Montgomery County requires a development permit for additions, plus a floodplain permit on lots in the mapped 100-year floodplain. Homes in College Park or Alden Bridge also need written approval from their Woodlands village Residential Design Review Committee.
BT Grace Homes confirms the jurisdiction from the address at the first conversation, so the design is drawn to the right rules from the start.
- Inside City of Conroe limits: city building permit and inspections
- Unincorporated Montgomery County: county development permit, floodplain permit on mapped lots
- College Park or Alden Bridge: Woodlands RDRC approval as well

Common questions about second story additions in Conroe (77384 & 77385)
Who permits a second story on a Conroe-addressed home in 77384 or 77385?
It depends on the exact address. Homes inside City of Conroe limits are permitted and inspected by the city's Building Inspections and Permits division. Homes in unincorporated Montgomery County need a county development permit, and Woodlands village homes in College Park or Alden Bridge also need RDRC approval.
Are 2000-era homes in Imperial Oaks good candidates for a second story?
One-story homes from that era often are. Homes from around 2000 are typically on slab foundations, and the deciding question is what the slab and walls can carry. A structural engineer evaluates that before design; where reinforcement is needed, it is designed and priced up front.
Can we keep living in the house during construction?
Yes. The new floor is framed and weatherproofed above your existing roof before the old roof comes off, so the house below stays sealed and livable while the second story goes up.
