Custom Home Projects in
Wimberley, Texas.
ClearBuild Texas takes on custom homes, large remodels, and additions in Wimberley and the surrounding valley in western Hays County.
Three questions shape a Wimberley project before a plan is drawn: how close the site sits to the Blanco River or a creek, how steep the lot is, and where the water will come from. Each one can change how much house the lot allows and what it takes to serve it.
This page is general planning information, not a price quote or construction schedule. Call or email ClearBuild with the property location and we will talk through what applies to it.

What to plan for in Wimberley
The river sets the site plan
Wimberley's Protected Waterway overlay reaches 150 feet from riverbanks and 100 feet from creek banks, or the mapped 100-year floodplain if that is larger, in the city limits and ETJ. A home inside it needs a site development permit first, and septic drainfields cannot go there. Where a floodplain applies, the city's plan checklist asks for finished floors at base flood elevation plus two feet, with a sealed elevation certificate.

The National Weather Service reports that in the May 2015 flood the Blanco River at Wimberley rose from near 5 feet at 9 p.m. to near 41 feet by 1 a.m., going from below flood stage to major flood stage in 45 minutes. Site elevation deserves early attention on any lot near the water.

Impervious cover limits apply to net site area, not the whole lot. Land over 15 percent slope counts at a reduced rate (30 percent of land at 21 to 25 percent slope, for example), and land over 35 percent does not count. Lots from 2 to under 5 acres in the R-1 district are capped at 20 percent of that net area. A site or footprint averaging over 15 percent can also trigger development plan review.

The city's checklist asks for a letter confirming service from Wimberley Water Supply or Aqua Texas where that applies. For a well, the Hays Trinity district requires notice before drilling. In November 2026 the district remained in Stage 4 emergency drought, and in Stage 3 or 4 new wells are limited to replacements and exempt uses. Land around Jacob's Well sits in its own management zone, with added limits on non-exempt wells.

The City of Wimberley sends on-site sewage permits to Hays County, and the city's building checklist asks for the approved county permit. The city also owns the Central Wimberley Wastewater System, so it is worth asking whether a parcel can connect before designing around septic.

Inside city limits, the city issues building permits and owners are responsible for calling for inspections. The schedule effective October 1, 2025 lists a $50 application, $75 plan review, $55 per inspection, and $40 plus $0.40 per square foot for a home, or $0.35 above 1,450 square feet. Foundation plans must be designed by a registered professional engineer, and additions need existing and proposed floor plans.

Common questions
Do I need a building permit in Wimberley?
Inside city limits, yes. The City of Wimberley issues building permits for new construction, and a floodplain permit can apply as well. Outside the city, Hays County rules apply, including a county development permit and septic permit.
Can I build near the Blanco River in Wimberley?
Sometimes. Construction inside the Protected Waterway overlay is generally prohibited, with listed exceptions that include single-family homes that meet city zoning and building rules. A site development permit comes first, septic drainfields are not allowed inside the overlay, and floodplain rules can add more requirements.
Can I drill a new well near Wimberley during the drought?
In Stage 3 or 4, the Hays Trinity district allows only replacement wells and wells for exempt uses, and it requires notice before drilling. Check the current stage and whether the land falls in the Jacob's Well zone before relying on a new well.
Does Wimberley have outdoor lighting rules?
Wimberley Valley, which includes Wimberley and Woodcreek, was designated an International Dark Sky Community in 2018, and the city's site development application lists an outdoor lighting plan. Plan the lighting with the design rather than after it.
Does ClearBuild Texas build in Wimberley?
Yes. Wimberley and the surrounding valley are part of ClearBuild Texas's service area for custom homes, large remodels, and additions.
