Zoning, building permits and septic rules in Robstown, Texas

Robstown, Texas, in Nueces County, has its own zoning ordinance, so land inside city limits is zoned1. The city's Building & Development Department handles building permits, zoning administration and plats2. Septic permits for Nueces County come from the Corpus Christi-Nueces County Public Health District3; whether that office also covers addresses inside Robstown is something we could not confirm, so ask it before you plan a septic system.

Does Robstown have zoning, and what does it mean for lot size and setbacks?

Yes. The City of Robstown adopted its own Zoning Ordinance, and it applies to land inside Robstown city limits1. The city is divided into seven classes of zoning district, and territory annexed later is treated as R-1 until the city council permanently zones it4.

Rules differ by district, so check the zoning map at the city secretary's office for your parcel. In the R-1 First One-Family Dwelling District, a lot needs at least 7,500 square feet and an average width of at least 60 feet7. The front yard must be at least 30 feet deep8, and a building may not exceed 2.5 stories or 35 feet9. In R-1, an accessory use must be customary and on the same lot, and servants' quarters cannot be rented or used commercially11.

Mobile-home subdivisions are a regulated special use, and their streets must meet city width, curb and gutter standards12. We could not confirm Robstown rules on RV occupancy, tiny homes, temporary camping or minimum home size, so call the Building & Development Department before relying on any of them2.

Do you need a building permit in Robstown, and who issues it?

The City of Robstown's Building & Development Department handles building permits, plats, rezoning, variances, conditional use permits and certificates of occupancy inside city limits2. The department reviews building plans against the building codes and the subdivision and zoning ordinances, and inspects residential, commercial and industrial work2.

We could not confirm the exact rule for which projects need a building permit, or whether an owner-builder exemption exists, so ask the department before you start. A certificate of occupancy is required before a new or structurally altered building is used, applied for at the same time as the building permit, and issued within 10 days after the work conforms5. The stated fee is $306. Vacant land may be used for agriculture before a certificate is issued, but that does not exempt it from other city rules13.

How do septic permits work in Robstown?

Septic permits in Nueces County come from the Corpus Christi-Nueces County Public Health District, the local agent for Texas's on-site sewage facility rules3. A permit is required to build, install, alter, extend or repair an on-site sewage facility, and new systems and repairs need an inspection1415.

We could not confirm whether the health district or the city administers septic systems at addresses inside Robstown, so call the district at (361) 826-7222 before you buy a lot that is not on city sewer10. For a single-family home on a tract of 10 acres or more, the state may allow an exemption from permitting16; a lot inside city limits is almost never that large.

Building a home in Robstown: the steps, in order

  1. Find your parcel's zoning district on the zoning map at the city secretary's office, and confirm the use you want is allowed there4.
  2. Call the Building & Development Department at 361-387-4589 to ask which permits your project needs2.
  3. Confirm sewer or septic with the city and with the Corpus Christi-Nueces County Public Health District10.
  4. Apply for the building permit and, at the same time, the certificate of occupancy17.
  5. Pass inspections, then receive the certificate of occupancy, which is issued within 10 days after conforming completion5.

What stays with Nueces County, and what to check before you buy

The county's rules cover unincorporated land, not Robstown city limits; see the Nueces County page for land outside the city. Inside or outside the city, driveways onto a Texas state highway need state approval18, and driveways onto county roads need approval from Nueces County Public Works19.

Nueces County's typical home value is about $230,02720, and its effective property tax rate is 1.7%21. Only about 2.9% of county soils rate as not limited for a conventional septic drain field, so expect a site evaluation and possibly an engineered system22. We could not confirm Robstown's flood-damage rules; ask the city before building near a drainage way.

Watch-outs

  • We could not confirm whether the city or the Corpus Christi-Nueces County Public Health District permits septic systems at addresses inside Robstown; call the district before you buy10.
  • The City of Robstown's general building-permit trigger, owner-builder exemption, and rules on RVs and tiny homes were not confirmed; ask the Building & Development Department2.
  • Zoning varies across Robstown's seven district classes, so the R-1 numbers here do not apply to every parcel4.
