Do You Need a Permit for Pressure Washing in Houston?

Short answer: yes. The City of Houston requires a Special Waste Service Company Permit from the Houston Health Department before you can legally operate a pressure washing business. This isn't optional — operating without it can result in fines and permit revocation.

Here's what you need to know.

Why Houston Requires a Permit

Pressure washing generates wastewater that contains dirt, oil, grease, paint chips, detergents, and other contaminants. In Houston, this wastewater is classified as regulated special waste because it can pollute storm drains and waterways if not properly captured and disposed of.

The Houston Health Department's FOG (Fats, Oils, and Grease) Program oversees pressure washing permits to protect the city's storm drain system and comply with federal Clean Water Act requirements.

What the Permit Requires

To obtain a Special Waste Service Company Permit in Houston, you must:

• Submit a typed application — effective with the 2026 application cycle, handwritten applications are no longer accepted
• Provide driver's licenses for all owners, managers, and drivers (clear photocopies)
• Pass an equipment inspection — the city tests your booms, mats, and recovery systems to verify you can capture all wastewater and protect storm drains
• File monthly reports — due on the 15th of each month, covering all regulated waste activity within Houston city limits

How to Apply

Contact the Houston Health Department's FOG Program:

Temporary permits are available for up to 93 days while your full application is processed. This lets you start operating while the city reviews your equipment and paperwork.

What Happens If You Don't Get the Permit?

Operating without a permit puts you at risk of:

• City enforcement action and permit denial
• TCEQ fines of up to $10,000 per day for illegal wastewater discharge
• Potential federal Clean Water Act violations
• Liability if your wastewater causes environmental damage

What Else Do You Need?

The pressure washing permit is the most critical Houston-specific requirement, but it's not the only thing you need. You'll also need:

• Texas LLC formation ($300 filing fee)
• Federal EIN (free)
• Texas Sales Tax Permit (8.25% collection required)
• General liability insurance ($1M/$2M recommended)
• Commercial auto insurance
• Wastewater recovery equipment (required by the city)
