A crack in a Mission Bend house raises a question most towns never have to ask: whose rules apply? Mission Bend has no city government. It's an unincorporated place that sits across the line between Fort Bend and Harris counties, and 10 of our 25 sample spots fell on the Harris side. So permits, flood rules and even subsidence oversight depend on which side your house is on.
The homes have a story of their own. Mission Bend built a larger share of its homes in the 1980s than any of the 22 towns we studied. If you're weighing foundation repair in Mission Bend, here's what the records say about the ground, the houses and the rules.

The Ground Under Mission Bend
On the state geologic map, most of the Mission Bend spots the map could place fell on the Beaumont Formation: 10 on its clay and 8 on its old sandy stream ridges. The soil survey shows what's on top of that. Here's how our 25 spots split:
- 11 very high. Lake Charles clay covers 9. It reads 12.4 at the surface and 13.6 from about a foot down. One spot landed on Churnabog clay at 14.3, and one on Pledger clay at 19, the highest reading in all 22 towns we studied.
- 7 high. Bernard reads 7.3 from about 6 inches down at 4 spots. Verland silty clay loam (7.5) and Edna (6.6) make up the rest.
- 7 moderate or low. Five of these fall on one Bernard map unit whose survey reading doesn't match its 30% to 52% clay. We counted them as low anyway. The other 2 read 4.0 and 2.5.
So the true share of active clay is likely higher than 18 of 25. Lake Charles clay is the one to know. The USDA says it cracks up to 2 inches wide in a dry spell and soaks up water fast through those cracks, then very slowly once they close. So after a dry summer, the first heavy rain can reach deep beside a slab before the clay seals up again.
Curious which of these is under your own yard? Type your address into the USDA's Web Soil Survey, a free federal map. Our Sugar Land soil guide explains what each soil name means.
Flood Zones in Mission Bend
We aren't quoting a floodplain share for Mission Bend. The rock map marks several of our spots as water that the soil survey reads as land, so any count would rest on spots we can't pin down. FEMA's map is the place to check your own address, and our flood zones guide walks through how to read it.
What we can say is who sets the flood rules. On the Fort Bend side, the county's flood damage prevention rules apply, and the county administers them for Mission Bend MUD No. 1 under an agreement. Those rules count a repair or improvement as substantial when it costs half or more of the house's value on the Fort Bend Central Appraisal District roll. A substantially improved house in a special flood hazard area must have its lowest floor at least 2 feet above the base flood elevation.
Mission Bend Homes by Decade
The Census counts 11,470 homes in Mission Bend, and the median one was built in 1986. Here's when they went up:
- Before 1960: 1.0%
- 1960s: 2.3%
- 1970s: 20.4%
- 1980s: 45.1%
- 1990s: 15.3%
- 2000s: 13.7%
- 2010s: 1.9%
- 2020 or later: 0.2%
Nearly half the homes date from one decade, and 67.8% went up from 1960 through 1989. That makes Mission Bend's housing older, as a group, than Sugar Land's or Stafford's. A slab from the early 1980s is now more than 40 years old, and it's been through four decades of wet and dry seasons.
Age alone doesn't mean a slab is failing. HUD's rehab inspection guide reads a crisp, clean crack as fresh movement, while a dirty or patched one may have stopped long ago. On a house this age, that difference is worth checking before anyone quotes a repair. A foundation inspection measures where the floors are now.

Permits and Rules in Mission Bend
With no city, the county is the authority, and it depends which county.
- Fort Bend side. Fort Bend County has adopted no building code for single-family homes, and it doesn't issue certificates of occupancy. It does require a Development Permit for building modifications and any work in the 100-year floodplain: $100, or $150 in a floodplain. Whether a slab repair counts as a building modification, the county doesn't say.
- Harris side. Harris County says a permit is needed for all development, which it defines as any man-made change to property, buildings included. It doesn't name foundation repair either.
Fort Bend County doesn't review house plans or inspect to a building code. That makes the company's own floor readings, and a written record of the work, more important. Before work starts, ask Fort Bend County Engineering (281-633-7500) or Harris County's permit office whether your job needs a permit. Our permits guide covers the cities and counties nearby.
Watering Rules in Mission Bend
Fort Bend County doesn't supply water, so your rules come from the utility district on your water bill. Several districts serve Mission Bend, and their drought plans differ.
North Mission Glen MUD's 2024 plan is one example. None of its stages mentions foundations. In its moderate stage, all outdoor watering must be done with a hand-held hose with an on-off nozzle. In its severe stage, all outdoor water use is banned.
If your district follows a plan like that, the time to keep the clay around your slab evenly moist is early in a drought, before the strictest stage. For how much water is enough, see the watering guide.

Mission Bend Questions
Is Mission Bend in Fort Bend County or Harris County?
Both. Of our 25 sample spots, 15 fell in Fort Bend County and 10 in Harris County. Your property tax statement will show which county your house is in.
Who issues a foundation repair permit in Mission Bend?
The county, not a city. Fort Bend County requires a Development Permit for building modifications and floodplain work. Harris County requires a permit for all development. Ask the right county before work starts.

The Fort Bend Subsidence District covers the Fort Bend side. The Harris side falls under the Harris-Galveston Subsidence District. Both regulate groundwater pumping, not individual houses.
Nearby Towns on the Same Ground
We serve Mission Bend and the towns around it, including Pecan Grove, Cinco Ranch, Sugar Land, Stafford and Richmond.
Cinco Ranch, to the north-west, sits on different ground: none of our 24 Cinco Ranch land spots came up very high. Stafford shares Mission Bend's Lake Charles clay, but it's a city with its own permits. See all service areas.
