Pressure washing in Austin

Austin's rule sits in City Code Chapter 6-5, Article 5. Power washing wastewater that contains pollutants or cleaning compounds and hasn't been treated may not go into the storm sewer. It can go to the sanitary sewer only one way: hauled to a permitted private fixed-site facility with pretreatment, such as a sand and oil interceptor or a grit trap.

That makes the method part of the quote. A company that soaps a driveway and lets the rinse run down the gutter is sending untreated wash water toward the storm sewer. Ask each bidder to describe, in writing, how it captures and disposes of wash water, and whether it uses chemicals at all on your surfaces.

Austin drought rules for pressure washing equipment

Under Austin's Conservation Stage restrictions, in force as of September 2, 2025, commercial power and pressure washing equipment must meet efficiency requirements. Ask the company to confirm its equipment complies with the current stage, and re-check the stage before a large job, because Austin Water changes stages as conditions shift. Breaking the water restrictions can cost up to $1,000 per violation.

Ask what license or registration, if any, the company holds. Beyond that, the useful checks are practical:

1. Wastewater plan. Get the capture and disposal method in writing, as above.
2. Sales tax permit. The Texas Comptroller taxes pressure washing of buildings, sidewalks and parking lots as building or grounds cleaning, at homes as well as businesses, and the company must hold a sales tax permit. Washing personal property, such as a boat or trailer, is taxable too.
3. Surface and method. Ask whether the crew will use high pressure, low-pressure soft washing or hot water for each surface, and who pays if siding, paint or screens are damaged.
4. Utility call. Austin Water tells operators to call Utility Compliance Services at 512-972-1060, option 5, before starting, so ask whether the crew has.

Washing a roof before a repair estimate, or a deck before sealing, often goes alongside other trades. See roofers in Austin and, for a move-out wash, house cleaning in Austin.

How Austin pressure washing rules compare

Texas cities handle washers differently. Fort Worth requires a city permit for mobile power washing, $25 per business plus $25 per registered wash unit, and San Antonio requires commercial power washers to register with its water system. Austin's own rules on wash water cover discharge and equipment, so ask the city through 3-1-1 whether any washer registration applies before a commercial job.

Austin bids vary, so compare them against HomeGuide's national figures, from pages dated April 2024 and June 2026.

Renting a machine runs $40 to $100 a day; if you use soap or degreaser yourself, ask Austin Water's Watershed Protection line (512-974-2540) where the rinse may go. The Texas pressure washing guide covers soft washing and sealing in more depth, and the Austin hub lists the city rules every trade shares. To compare, see pressure washing in Round Rock.
