Every Driftwood listing sheet leads with the same line: no city, no city tax. It's accurate. Driftwood is unincorporated Hays County, which means there's no municipal government levying a city rate on top of what the county and the school district already collect. On a $1.5 million estate, that absence can mean $4,000 to $8,000 a year that an equivalent home inside an incorporated Austin suburb would owe and a Driftwood owner doesn't.
What the pitch leaves out is what fills the gap. Driftwood doesn't have a zoning board telling you what you can build, but it has a septic permit that does something close to the same job, and it does it earlier and more specifically than most buyers expect.
The Permit That Sets Your Ceiling
Almost every home on acreage in Driftwood runs on an on-site sewage facility, the septic system Hays County calls an OSSF. The county requires a permit for every OSSF in its unincorporated territory regardless of lot size or acreage, and the system's design isn't a generic template. It's sized by a licensed septic designer based on the number of bedrooms, the square footage of the house, the strength of the wastewater, and the soil on that specific parcel.
That sizing follows the house for as long as it stands. If a future owner wants to add a bedroom, build a guest suite, or expand the square footage, Hays County's own rules state that the addition may require a new development permit and an upgrade to the existing OSSF. The permit doesn't ask whether the lot is zoned for it, because there's no zoning to ask. It asks whether the septic system on file can handle the load, and if it can't, the expansion waits on a redesign before it can move forward.
New construction adds another layer. Under a 2009 state law, counties above a certain population threshold can require unincorporated new homes to pass a minimum of three inspections, at the foundation stage, and again at framing and mechanical, before drywall goes up. Hays County has that authority. A buyer touring a newly built Driftwood home should ask whether those inspections happened and whether the records exist, the same way they'd ask a city building department for a certificate of occupancy anywhere else.
None of this makes Driftwood harder to build in than an incorporated suburb. It makes the restriction sit in a different office, under a different name, tied to different paperwork. A buyer who assumes "no zoning" means "no ceiling" finds out otherwise the first time they price out a pool house.
The Tax Line That's Real, and What Sits Next to It
The no-city-tax framing is true as far as it goes. Property owners in Driftwood pay Hays County taxes and school district taxes, primarily to Dripping Springs ISD, and nothing to a city because there isn't one. But two Hays County Emergency Services Districts still cover the area: ESD #1 provides EMS to Dripping Springs, Driftwood, and Henly, and ESD #6 provides fire and rescue to Dripping Springs and Driftwood. Both are ad valorem taxing entities, meaning they show up on the tax bill as their own line, funded the same way a city fire department would be, just organized as a special district instead of a city department.
The honest comparison isn't "Driftwood taxes less" against "the suburb taxes more." It's that Driftwood substitutes a county-plus-ESD-plus-ISD stack for a county-plus-city-plus-ISD stack, and the difference in the total often does favor Driftwood, but the savings shows up alongside costs a city resident doesn't carry directly: a private well that needs its own testing and maintenance, a septic system with its own service contract if it's an aerobic unit, and in some cases a private road that isn't on the county's maintenance list. The tax line is smaller. The list of things you're now personally responsible for is longer.
Why the Median Price Depends on Which Three Houses Closed
Ask three different sources what the median home price in Driftwood is right now and expect three different answers, and not because anyone's data is wrong.
As of this September, one tracker's trailing 12-month window shows a median of roughly $1,005,000, down about 11 percent from the year before, based on 85 closed sales. A separate count of MLS closings from June 2025 through June 2026 shows 82 single-family homes selling at a median of $1,027,500, or $317 per square foot, with an average closing price of $1,103,902. Back in May 2025, a different tracker recorded a median of $1.3 million, up 34 percent year over year, a figure that has since cooled well below that peak. And Zillow's home value index, which estimates typical value across the entire housing stock rather than just what changed hands that month, put Driftwood's average home value at $898,615 as of late summer 2026, down 4.5 percent year over year.
Those aren't four opinions about the same market. They're four different windows onto a market that closes something like 80 to 85 homes a year, or roughly seven a month. In a market that size, one $2.2 million compound closing and one $600,000 entry-level acreage sale in the same month can swing the median by tens of thousands of dollars without any underlying shift in what Driftwood real estate is worth. A median calculated from seven transactions is a description of which seven houses sold, not a stable read on the neighborhood.
This is also why professionals who track the area closely tend to talk in ranges instead of single numbers. One regional market guide puts the median for transacted Driftwood acreage properties at $950,000 to $1.2 million for 2025 and 2026, describing that as roughly 8 to 12 percent below the 2022 peak. A range that wide isn't hedging. It's the accurate way to describe a market where the sample size is small enough that last month's number and next month's number can legitimately disagree by six figures.
For a buyer, the practical takeaway isn't to pick a favorite tracker. It's to ask what window and what sample size sit behind any number you're handed, because in Driftwood, the answer changes the number more than the market does.
What to Check Before You Compare Two Numbers
- Ask for the property's OSSF permit and confirm what bedroom or square footage count it's currently rated for, especially if you're planning to expand
- Request well records, including depth, yield history, and the most recent water test, since maintenance and testing costs fall to the owner
- Confirm which Emergency Services Districts serve the specific parcel and what their current tax rates are, since ESD #1 and ESD #6 both bill separately from the county
- If the home is new construction, ask whether foundation and framing inspections were completed and documented under Hays County's development permitting
- Find out whether the access road is county-maintained or privately maintained, since that affects long-term cost even though it rarely appears on a listing sheet
- When you're handed a median price for Driftwood, ask what time window and how many closings it's based on before comparing it to a number from another source
FAQ
Does "no zoning" in Driftwood mean there are no real restrictions on what I can build? Not in practice. There's no zoning board, but Hays County still requires development and OSSF permits for construction in unincorporated areas, and septic capacity tied to bedroom count and square footage sets a real limit on additions.
Why do I see such different median home prices for Driftwood depending on where I look? Driftwood closes roughly 80 to 85 homes a year. With that few transactions, a single high-end estate sale or a single entry-level acreage sale can move the calculated median significantly from one month or one data source to the next. The differences reflect small sample size, not disagreement about the market.
Is Driftwood served by one school district? Most of Driftwood falls under Dripping Springs ISD. Confirm the assigned district for a specific address before making assumptions, since boundaries can shift near the edges of unincorporated areas.
If you're weighing a specific Driftwood property against a home in an incorporated suburb and want help pricing what the tax line actually saves you against what the septic and well setup will actually cost, Friedman Real Estate can walk through the numbers on that particular parcel with you.
