About the area

Living in Spring

Spring sits between I-45 and the Hardy Toll Road north of Houston, and it is one of the places where the county line matters. The 77373 and 77388 ZIP codes are in Harris County; 77386, to the east, is in Montgomery County. Same name on the mailing address, different taxing authorities, different ISD, different county services.

Old Town Spring is the historic center — small lots, older houses and the shop district — while most of the residential market is postwar subdivisions spreading out from it, with newer development toward The Woodlands on the Montgomery side.

Schools are split across Spring ISD, Klein ISD and Conroe ISD, broadly tracking that county line but not neatly. The district is set by the address. If schools are driving the search, confirm the zone for the exact property before anything else.

The county split is the thing to model before you shortlist. Property tax rates, exemptions and the appraisal district all change when you cross it, so two similar houses a mile apart can carry noticeably different monthly costs. Work with the all-in number, not the list price.

Questions

About buying and selling in Spring

Is Spring in Harris County or Montgomery County?
Both. The 77373 and 77388 ZIP codes are Harris County; 77386 is Montgomery County. That changes the tax rate, the exemptions, the appraisal district and the county services, so establish which side a property is on before you compare it to anything.
Which school district serves Spring?
Spring ISD, Klein ISD and Conroe ISD all serve parts of it, broadly tracking the county line but not neatly. Zoning is set by the address, not by the ZIP code or the subdivision name, and districts here redraw attendance zones as new campuses open. Two houses on the same street can be zoned differently. Check the current zone for the exact property before you decide anything on the basis of schools.
What is Old Town Spring like compared with the rest?
Smaller lots, older houses and the historic shop district. Most of the residential market is postwar subdivisions spreading out from it, with newer development toward The Woodlands on the Montgomery side.
Does this area flood?
Parts are and parts are not, and the maps have been revised since Harvey. Flood designation is per property, not per neighborhood. Ask for the current zone, the full claims history and an insurance quote during the option period, when you can still act on the answer.
