Car washes need zoning approval and a permit to send wash water to the sewer, usually with an oil-water separator. Rules come from your city and your local sewer authority, so check with both before you buy land or sign a lease.

Why Rinse Bros Car Wash closed: a 60% rent rise and doubled energy bills

Rinse Bros had steady demand and good reviews, but it didn't control its biggest costs. When energy prices doubled in 2023 and the landlord raised the rent 60% at the 2025 renewal, break-even jumped from about 1,450 washes a month to 2,300. The site had never done more than 1,700.

Questions people ask

How much does it cost to start a car wash?

It depends on the format. Self-serve bays cost the least; an express tunnel with land can run into the millions. Buying a running wash is often faster than building.

Do car washes need special permits?

Usually zoning approval, often with a special or conditional use permit, plus building permits and a permit from your sewer authority for wash water. Many cities require an oil-water separator.

Why do car washes sell memberships?

Monthly memberships give steady income that does not depend on the weather, and members tend to wash more often.
