New Braunfels building permit framework — 2021 ICC
New Braunfels Building Safety administers permits under the 2021 ICC (effective October 23, 2023) and 2020 NEC. All permits through online portal at newbraunfels.gov/permitportal. Inspections: portal only (no email). NBU provides electric for majority of city; CenterPoint Energy provides gas to many but NOT all areas. Texas TDLR for all trade contractors. Phone: 830-221-4000.
Zone 2A hot-humid Hill Country: 90°F+ summers (May–September), ~34 inches annual rain, no frost depth, slab-on-grade dominant, limestone geology. Cooling efficiency, SHGC ≤ 0.25 windows, moisture management are the defining construction requirements.
One of the fastest-growing US cities: Hill Country lifestyle, Comal/Guadalupe River access, German heritage, between San Antonio and Austin. Large short-term rental market. Gas service not universal — verify at 830-643-6937. 2021 ICC + 2020 NEC effective October 23, 2023. NBU municipal electric utility.
New Braunfels solar permit rules — NBU net metering and Texas HOA protection
Solar PV installations in New Braunfels require two permits: a building permit (structural roof mounting, racking installation, roof penetration flashing — note Texas SB 1202 considerations for roofing contractors involved in solar mounting) and an electrical permit (2020 NEC Article 690: DC wiring, AC disconnect, rapid shutdown devices, inverter, backfeed breaker at the electrical panel). All permit applications through the online portal at newbraunfels.gov/permitportal.
New Braunfels Utilities (NBU) is the municipal electric utility for most of New Braunfels — a city-owned utility whose solar interconnection process is administered through the same city government that issues building permits. After city permits close and all inspections pass, the homeowner or installer submits a solar interconnection application to NBU. NBU processes the application and installs a bi-directional net metering meter. Contact NBU at nbutexas.com for current solar net metering program terms and interconnection application requirements before finalizing solar project scope. Properties in the GVEC service area (south of County Line Road) coordinate solar interconnection with GVEC (830-386-4424) instead of NBU.
Texas Property Code Section 202.010 prohibits HOAs from unreasonably preventing solar installations — a critical protection in New Braunfels's many HOA-governed planned communities and new developments. HOAs may impose reasonable aesthetic conditions (limiting panel visibility from the street, requiring specific mounting) but cannot ban solar outright. Conditions increasing cost by more than a specified threshold or reducing performance by more than 10% are deemed unreasonable. Obtain HOA approval before submitting city permits — some New Braunfels solar permit submittals include HOA approval documentation. The Texas Property Code solar protection ensures that homeowners throughout New Braunfels's HOA-governed growth areas can install solar without fear of HOA prohibition.
New Braunfels's Zone 2A location at approximately 29°N latitude provides an excellent solar resource. The Hill Country's typical clear-sky conditions, with approximately 5.0–5.2 peak sun hours daily averaged annually, provide strong solar production. A 7 kW system in New Braunfels produces approximately 10,000–11,500 kWh annually. Texas financial incentives: federal 30% Residential Clean Energy Credit through 2032, no Texas state income tax (full 30% credit retained), no Texas state sales tax on solar equipment, and property tax exclusion under Texas Property Tax Code Section 11.27. New Braunfels does not have a SREC (Solar Renewable Energy Credit) market — unlike Illinois in this guide.

New Braunfels in the context of Texas and this guide
New Braunfels occupies a distinctive position among the Texas cities in this guide series. College Station TX adopted the 2024 ICC effective January 1, 2026 — one code cycle ahead of New Braunfels's 2021 ICC (effective October 23, 2023). Sugar Land TX also adopted the 2024 ICC effective January 21, 2026. New Braunfels's 2021 ICC adoption represents solid current-code compliance for a rapidly growing Texas city — well above the 2018 ICC still used by some Texas jurisdictions. The 2020 NEC adopted alongside the 2021 ICC is two editions behind the 2023 NEC used by Sugar Land and College Station, but more current than the 2017 NEC found in many Texas communities.
The most distinctive features of the New Braunfels permit environment relative to other Texas cities in this guide are: the explicit cosmetic work exemption list (which the city publishes on its website); the gas service availability variable (CenterPoint Energy does not serve all of New Braunfels — propane and all-electric systems are common in outer areas); and the NBU municipal utility structure (city-owned electric utility providing solar net metering integration). The online permit portal at newbraunfels.gov/permitportal and the ProjectDox plan review software reflect the city's investment in efficient digital permitting — appropriate for one of the nation's fastest-growing cities. The online-only inspection request requirement (since August 2024) eliminates the email-based backlog that previously created inspection scheduling delays. All of these features combine to make New Braunfels's Building Safety Division a responsive and well-organized permitting authority for the city's extraordinarily active construction market. Contact Building Safety at 830-221-4000 for specific guidance on any permit requirement, required documentation, or current review timelines before submitting any application through the online portal.
