  2. General Liability Insurance (Recommended, Not Required)

    Michigan does not require pressure washing businesses to carry general liability insurance. Pressure washing is not among the occupational professions LARA's Bureau of Professional Licensing regulates under the Michigan Occupational Code, so no state licence, bond, or minimum coverage limit applies. Coverage is driven by private contract instead: commercial clients and property managers commonly require a certificate of insurance, and the limits are whatever each client's contract specifies, so confirm them per client rather than assuming a standard figure. Commercial auto coverage is required separately for any vehicle used in the business under Michigan's no-fault vehicle insurance law, which applies to the vehicle rather than to the pressure washing trade. Note also a real regulatory obligation the claim omits: wash water must not be discharged to storm drains — inside Detroit that is regulated by DWSD.

    Set by the private insurance market — Michigan mandates no general liability coverage for this trade and publishes no premium. Cost varies with carrier, required limits, revenue, equipment, and claims history. Michigan no-fault auto coverage for a business vehicle is a separate, legally required cost.No state process and no regulatory waiting period; binding a policy is a commercial transaction whose speed depends on the carrier and underwriting. Clients typically require the certificate of insurance before work begins, so obtain it before bidding contracts.

City of Detroit / Wayne County

3 stops

  1. Detroit Business License

    The City of Detroit does not require a general business license, and business licensing is administered by BSEED (Buildings, Safety Engineering and Environmental Department), not the City Clerk's Office. BSEED licenses only specific enumerated categories (vendors, lodging, amusement venues, consumer services, gas stations, second-hand dealers) — pressure washing is not among them, so no annual renewal or gross-receipts-based license fee applies.

  2. Stormwater / Wastewater Discharge Compliance

    Pressure washing businesses operating in Detroit must not allow wash water containing detergents, oils, sediment, or other pollutants to enter storm drains. Inside the city the responsible local authority is the Detroit Water and Sewerage Department (DWSD), not Wayne County — DWSD administers Detroit's Post-Construction Stormwater Ordinance (approved by the Board of Water Commissioners and City Council in 2018) and the city's combined sewer system, and publishes a Stormwater Management Design Manual. Wash water generally must be contained and discharged to the sanitary sewer with DWSD's approval, or collected and disposed of properly, rather than released to a storm drain. At the state level EGLE regulates discharges to surface waters and stormwater under Michigan's water quality program. Working outside Detroit in the rest of Wayne County, contact the county's environmental health program instead.

    Official government source

    No permit fee applies to the general compliance obligation itself; DWSD drainage charges and any discharge authorization or industrial waste requirements are billed separately by DWSD. Confirm with DWSD whether your operation needs a specific discharge authorization (needs_review).Ongoing compliance obligation with no application step; any DWSD authorization or plan submittal follows DWSD's own review schedule

  3. DBA (Assumed Name) Registration — Wayne County

    If operating as a sole proprietor or partnership under a trade name, file a Certificate of Persons Conducting Business Under an Assumed Name (or a certificate of co-partnership) with the Wayne County Clerk before accepting jobs under that name. The Clerk states the process requires no appointment and is completely mail-in: all signatures must be notarized, with the notary's printed or stamped name and expiration date on each certificate, and two certified copies are returned after filing. Check name availability against both Michigan's state Business Entity Database and existing county registrations first. If instead operating as an LLC or corporation, the assumed name is filed with Michigan LARA at the state level, not the county.

    Official government source

    $16.00 filing fee, mailed with the notarized original certificate to the Wayne County ClerkMail-in only; the Wayne County Clerk publishes no processing time, and notarization must be completed before mailing (needs_review)
