No — a homeowner pressure washing their own house, driveway, or deck doesn't need a permit in Indianapolis or anywhere else in Indiana. Where it gets more nuanced is on the contractor side, and it's worth understanding since it affects who you're comfortable hiring.
Homeowners: No Permit Needed
Routine exterior cleaning — house washing, driveway cleaning, roof soft washing, deck cleaning — falls under normal property maintenance and doesn't require a permit from the city or county, whether you do it yourself or hire it out. This is different from something like a structural renovation or exterior remodel, which would trigger permitting requirements.
Contractors: No Statewide License, But Local Rules Vary
Here's the part that surprises people: Indiana doesn't issue a statewide general contractor license the way states like California or Louisiana do. Licensing decisions are left to individual cities and counties, which means requirements for a pressure washing business can vary depending on exactly where they operate. Some municipalities require a local contractor license or registration; others don't specifically regulate this trade at all.
What Indiana Does Require: The Home Improvement Contract Act
Regardless of local licensing specifics, Indiana's Home Improvement Contract Act (IC 24-5-11) requires a written contract for any residential home improvement work over $150 — which covers most pressure washing jobs. That contract needs to spell out the scope of work and price before work begins. A company unwilling to provide this, license or no license, is not operating the way Indiana law expects.

Why "No Statewide License" Doesn't Mean "No Standards"
The absence of a single statewide license doesn't mean anything goes. Insurance, a written contract, and proper wastewater handling (see is it legal to pressure wash your driveway?) are the practical standards that actually protect you as a homeowner — arguably more directly relevant than a license number would be. We cover the full list of what to check for in how to choose a pressure washing company.
What About HOA-Required Cleanings?
Some HOAs require exterior cleaning on a schedule as part of their governing covenants — that's a private contractual matter between you and your HOA, separate from any city or state permitting question. Worth knowing if your community has specific rules; see our dedicated post on HOA exterior cleaning rules.
The Practical Takeaway
Skip worrying about permits for routine cleaning — you don't need one. Instead, put your attention on insurance, a written contract, and responsible wastewater practices when hiring. We meet all three on every job throughout Indianapolis and suburbs like Noblesville.
