Quick Answers About New Braunfels, TX ADUs
Market Context
New Braunfels has a median home value of $320,000. Adding an ADU typically increases that by 22% — approximately $70,400 in added equity. A 1-bedroom ADU in New Braunfels rents for approximately $1,238/month in the Comal County rental market , yielding a 3% cap rate on the investment. Occupancy averages 90% in this market.
Top New Braunfels neighborhoods for ADU investment include River Chase, Oak Run, Mission Oaks, Town Creek, Manor Creek. High single-family density with large lots and high median values — good for detached ADUs and strong rental demand. Established single-family neighborhood with mid-to-large lot sizes and stable rental interest.
Permit Process
Permit applications are reviewed by the Development Services , with a plan check timeline of approximately 6 weeks. Permit fees in New Braunfels range from $4,056 to $4,636 depending on project scope. Design review: Yes - in historic districts only
Many older lots in New Braunfels sit on septic systems regulated by Comal County, not the city, so adding an ADU often triggers a separate septic evaluation to confirm the tank and drain field can handle the extra bedroom load — a step people forget until Development Services kicks their application back. If your property falls within GBRA's (Guadalupe-Blanco River Authority) water service area instead of city water, you'll also need a separate letter confirming capacity for the second unit, which can add real waiting time since GBRA and the city don't always sync their timelines. Because short-term rental use isn't allowed for ADUs here, several lenders in the area also won't count projected rental income toward financing, which catches homeowners off guard when they're budgeting at $350/sqft.
"In my experience, that $350/sqft figure and the 6-week timeline are New Braunfels state-level estimates, not gospel — I'd get at least two local contractor quotes and call Development Services directly before penciling in a budget or move-in date. I've also seen plenty of "6-week" submittals stretch past 10 once corrections come back, so don't count on that clock starting until your drawing set is genuinely complete."

Local Zoning Rules
2026 New Braunfels ADU Rules
New Braunfels's 2026 ADU ordinance caps new units at 1,200 sq ft and 25 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run wide — 5 ft side / 10 ft rear — which pushes the buildable envelope toward the center of the lot. New Braunfels doesn't trigger the extra engineer-stamp requirement we see in higher seismic-risk or hurricane-code cities — a standard code-compliant ADU under the size cap can typically be designed and submitted without an architect or engineer stamp, though any load-bearing change to the existing house still needs one.
Permit fees run $4,056–$4,636 — in line with what most homeowners budget for permitting, and plan check takes about 6 weeks at Development Services. Submit directly to the department online — link below.
