New Braunfels's ETJ Is About to Get Bigger

Case-by-case / verify locally

New Braunfels's extraterritorial jurisdiction (ETJ) currently extends 3.5 miles beyond city limits, consistent with the 50,000-99,999-population band under Texas Local Government Code Sec. 42.021, and Texas law expands a city's ETJ to 5 miles once its certified population passes 100,000 -- a threshold current population estimates (roughly 111,000-116,000 as of 2023-2024) suggest New Braunfels, one of the fastest-growing cities in the country, may already be at or very close to. Land that sits outside today's ETJ ring toward the county's rural edges could fall inside it as the city grows, bringing city subdivision-platting review to land that's currently only subject to county rules. Confirm current ETJ status directly with New Braunfels Planning Services before assuming a specific parcel's status is fixed.

County and City Platting Authority Is Genuinely Limited

Case-by-case / verify locally

Local reporting on Comal County and New Braunfels development describes both entities as having "almost no authority to say no" to a proposed subdivision under Texas platting law -- a plat that meets the technical requirements in the county's Subdivision Regulations (or, within New Braunfels's ETJ, the interlocal agreement between the city and county) is generally entitled to approval, regardless of local preference about the pace or location of growth. Practically, this means the county's subdivision regulations set the ceiling on what can be required of a new development, but they generally can't be used to block or slow a plat that complies with them.

Two Separate Agencies Regulate Groundwater Here

Case-by-case / verify locally

Roughly half of Comal County sits within the Edwards Aquifer Authority (EAA), a special-law entity with its own well-registration and pumping rules distinct from a typical Water Code Chapter 36 groundwater district, while the newer Comal Trinity Groundwater Conservation District (created 2015) separately manages the deeper Trinity Aquifer. Depending on where a parcel sits and how deep a well needs to go, you may need to deal with one agency, the other, or both (a Trinity well that must physically pass through the Edwards zone needs an EAA "pass-through" permit in addition to Comal Trinity's own permit). See our standalone well-water page for the full picture -- this is genuinely more complex than the single-GCD picture most Texas counties present.

Short-Term Rentals Need a River-District Permit, Not Just a City/County One

Case-by-case / verify locally

Any water-related tourism business in the Water Oriented Recreation District of Comal County (W.O.R.D.) -- including short-term lodging, guide services, and equipment rental around Canyon Lake and the Guadalupe River -- needs its own W.O.R.D. permit and pays a 3% lodging user fee, on top of whatever county septic/OSSF or zoning-adjacent rules apply. See our standalone short-term-rentals page for the specific permit and fee structure.
