Zoning, building permits and septic rules in Post, Texas

The City of Post, Texas, in Garza County, requires building permits for many residential projects, issued through its Code Enforcement department at City Hall1. Post also zones land inside city limits2. Septic permits are a separate question: Garza County appears to be the state-authorized septic agent, and we could not confirm the rule for lots inside the city3.

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

Yes. The City of Post divides the land inside city limits into zoning districts, seven in all, and the district map is kept on file with the city secretary25. Land the city annexes later is classified R-1 until the city reclassifies it by ordinance5.

Dimensional rules depend on the district. In an R-1 single-family district, an accessory building must sit at least 50 feet from the back of the street curb and at least 5 feet from every other property line11. Accessory buildings in R-1 are limited to one story and 14 feet from ground level to the roof peak12. We could not confirm the minimum lot size or the main-house height limit for R-1, so ask City Hall for the district rules before you buy13.

Manufactured homes are not banned. A HUD-code manufactured home is allowed in an area the city finds appropriate and that zoning permits, and the city must approve or deny the application in writing by the 45th day7.

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

Inside Post, the city issues building permits, not Garza County. The city's permitting page states that permits are required for many residential projects and that applications are picked up at City Hall1. The city has adopted the 2015 International Residential Code for detached one- and two-family homes and townhouses4.

A site plan or survey must accompany a permit application for new construction, additions, accessory buildings, driveways and fences14. Fees are based on project cost and set by the city council6. The city's page lists $10 for new construction or additions with estimated work under $2,000 and $20 over $2,0001. Starting work before getting the permit doubles the fee1.

Owner-builders: if you do the work yourself, the city issues the permit to you rather than a contractor1. We could not confirm whether the city requires inspections or a certificate of occupancy, so ask Code Enforcement when you apply.

How do septic permits work for a home in Post?

Septic permits do not come from the city's building permit counter. Texas requires a permit and an approved plan to construct, alter, repair, extend or operate an on-site sewage system8. Garza County appears to be the TCEQ-authorized agent for the entire county, with TCEQ's Lubbock regional office covering anything outside that area3.

We could not confirm who permits septic systems on lots inside Post, or whether the city requires sewer connection for a new dwelling. Ask City Hall at 806-495-2811 whether your address has city sewer before you plan a septic system1.

The state's 10-acre exemption is aimed at large rural tracts: a single home on at least 10 acres, with every part of the system at least 100 feet from the property line, plus a licensed site evaluation8. A town lot will not meet that test.

Can you live in an RV or tiny home in Post?

We could not confirm a rule. Post's zoning ordinance addresses parking and maintenance of recreational vehicles in R-1 districts, not living in one, and no official tiny-home rule turned up2. Because the city zones its land, the county's lack of zoning does not carry over into Post2.

Before you buy a lot, ask City Hall at 806-495-2811 which district it falls in and whether an RV or tiny home can be occupied as a dwelling there1. A tiny home built to a recognized code may be reviewed under the 2015 residential code the city adopted4; confirm that with Code Enforcement.

Building a home in Post: the steps, in order

  1. Ask City Hall which zoning district the lot is in and what that district allows5.
  2. Check whether the lot has city sewer. If not, confirm the septic permitting office before you design the system3.
  3. Prepare a site plan or survey14.
  4. Pick up and submit the building permit application at City Hall, before any work starts1.
  5. Pay the permit fee, which the city sets based on project cost6.
  6. Build to the 2015 International Residential Code the city has adopted4.
  7. If your driveway meets a state highway, apply to TxDOT on Form 1058 before building on the right of way15.

What stays with Garza County, and what to check before you buy in Post?

The county's rules apply to unincorporated land, not inside Post. Garza County's building permit rule applies only to subdivisions, and the county's page says so16. For land outside city limits, see the Garza County page.

County-level figures help with context. Garza County's effective property tax rate is 1.7% and the median property tax bill is $1,316 a year1718. Annual precipitation is 20.6 inches, so water supply and drought deserve a close look19. About 31% of county soils rate as not limited for a conventional septic drain field, which means many lots need a site evaluation or an engineered system20.

We could not confirm the city's rules for wells, flood-hazard development permits or driveway access inside Post. Ask City Hall about each before closing.

Watch-outs

  • Septic authority for lots inside Post is unconfirmed, so call City Hall at 806-495-2811 and the county before you buy a lot without city sewer1.
  • The city doubles the permit fee when work starts before the permit is issued1.
  • The R-1 minimum lot size and main-house height limit were not confirmed, so get the district rules in writing13.
  • Manufactured homes depend on the zoning district and any deed restrictions on the lot7.
