Tomball

Tomball is the northwest corner of Harris County, and it covers more ground than people expect. The 77375 ZIP is the town itself and the subdivisions around it; 77377 reaches out to Rosehill, where lots get bigger and some of them are measured in acres rather than feet.

That range is the whole character of the market here. You can buy a standard subdivision house on a standard lot, or you can buy acreage twenty minutes away with a well, a septic system and a barn. Those are two completely different transactions: acreage brings septic and water inspections, different lending, and a survey that actually matters.

Most of the area is zoned to Tomball ISD, with Klein ISD and Waller ISD taking parts of the edges. Confirm the zone for the specific address rather than assuming from the ZIP code, particularly out toward Rosehill where the boundaries are not where you would guess.

Grand Parkway access changed this market and is still changing it. Newer development near the corridor tends to sit in a Municipal Utility District, which adds its own rate on top of the county and school rates; older Tomball closer to the town center often does not. Ask for the MUD rate on any specific home.
