What Drives the Cost

First Steps

  1. Study competitors near your site: use our state and city pages to see which wash types already exist.
  2. Check zoning, water discharge permits and sign rules with your city.
  3. Talk to the free SBA and SCORE advisers about a business plan and financing.
  4. If buying an existing wash, get several years of financials, equipment age and any environmental reports reviewed by a professional.
