Navasota is in Grimes County, about 24 miles northwest of our Magnolia office, where SH 105 and SH 6 meet a historic downtown and then open into ranch and acreage country. The usual drive from Magnolia runs out FM 1774 through Plantersville and west on SH 105, or around to SH 6. Navasota already appears on our Service Areas list.

Exteriors of Texas (EOT Builders) builds metal buildings, barndominium shells, and move-in-ready custom homes for Navasota-area landowners. In town, city permits and zoning apply. Outside town, Grimes County rules apply, and the land is often a larger tract with rural water and an on-site septic system. That is where most of this kind of building belongs.

What we build in Navasota

  • Metal buildings for shops, equipment, and agricultural use, with openings sized for farm and ranch equipment.
  • Barndominium shell packages if you want the structure closed in first and the living space finished later.
  • Turnkey barndominiums and custom homes when you want a finished, move-in-ready house from one builder.

Rural lots around Navasota often need a house and a separate shop. We plan both on the survey so driveway, drainage, and septic capacity are not afterthoughts.

Typical pricing

These figures are typical ranges and depend on design, the site, and finishes.

  • Shell-only packages typically start around $50–$80 per square foot.
  • Move-in-ready custom builds typically run $130–$200 per square foot under roof.

A raw Grimes County tract can need more land clearing, driveway, septic, well, or electrical-tie-in work than a lot already served by city utilities. Those items are not included in the per-square-foot price and are quoted separately.

Building in Navasota: local considerations

Inside the city limits, the City of Navasota Development Services Department handles planning, zoning, and floodplain matters, and building permits are filed through the city’s CitizenServe portal.

On unincorporated Grimes County land, a Development Permit is required for development. The county adopted the 2021 International Residential Code for new homes in unincorporated areas beginning in late 2024. The builder files a Notice of Construction and a Notice of Inspection with the county; Grimes County does not inspect the residential structure itself. Floodplain work requires a separate floodplain development permit, with sealed engineering and, for structures, an elevation certificate. Septic systems are permitted by Grimes County Environmental Services.

If the tract is low-lying or near a creek or the Navasota River, we treat flood-map review as a first-step item. A Navasota mailing address does not tell you whether the city or the county is in charge.

How a Navasota project typically proceeds

  1. Send a quote request at our contact page with ZIP, project type, size, land status, and timeline.
  2. Confirm city or county jurisdiction and walk the site for access from SH 105 or SH 6, drainage, and utilities.
  3. Prepare plans and file city permits, or county development, septic, and floodplain filings, plus the county’s construction and inspection notices on unincorporated homes.
  4. Build the metal building, shell, or finished home.
  5. Walk the project with you and complete city inspections or county close-out, including any electrical-service documentation the county requires.

FAQ

Do I need a City of Navasota building permit or a Grimes County development permit?
If the lot is inside the city limits, you work with Navasota Development Services and the city’s permit portal. If it is unincorporated county land, you need a Grimes County Development Permit and, in most cases, a septic permit. We confirm that from the official record before we design.

Will the county inspect my house?
Grimes County does not inspect residential structures in the unincorporated area. It does require the builder to file construction and inspection notices under the adopted residential code, and it approves septic work and floodplain documentation when those apply.

Is Navasota too far for you to build?
No. It is about 24 miles from our Magnolia office and is already listed on our Service Areas page. We schedule Navasota-area projects as part of our regular work, not as a one-off trip.
