1. Connecticut Sales and Use Tax Permit

   Any business selling, renting or leasing goods, selling an enumerated taxable service, or operating a hotel, motel, lodging house or bed and breakfast in Connecticut must register with the Department of Revenue Services for sales and use tax. Registration is done online through myconneCT under 'New Business/Need a CT Registration Number?'. DRS issues a Sales and Use Tax Permit that must be displayed conspicuously for customers. A separate permit is required for each business location, and a buyer of an existing business cannot use the previous owner's permit - a new one must be obtained.

2. General Liability Insurance (commercial requirement, not a government license)

   Connecticut does not require a pressure washing business to carry general liability insurance as a condition of operating - there is no state licence for the trade and no statutory minimum coverage. In practice it functions as a commercial gate: commercial clients, property managers and municipalities routinely require a certificate of insurance, commonly at $1 million per occurrence, naming them as additional insured before awarding work. Separate coverages apply to other exposures: commercial auto insurance is required for company vehicles under Connecticut's motor vehicle financial responsibility rules, and workers' compensation coverage is mandatory once the business has employees. Note that Stamford, New Haven and Hartford building permit applications require a workers' compensation affidavit or certificate of liability insurance from contractors.

1. No Hartford general business license for pressure washing (category-specific licensing only)

   Hartford does not issue a general business license covering all businesses, and Connecticut has no statewide one. Licensing is handled by the Licenses & Inspections division within the Department of Development Services - not the Town & City Clerk's office - and applies only to specific regulated categories such as food establishments, vendors, laundromats, amusement devices and parking lots, with applications filed through the city's Accela permitting portal. Pressure washing is not among them, so there is no annual licence to renew and no gross-receipts-based fee. A pressure washing operator still files a trade name certificate with the Town & City Clerk if trading under an assumed name and must keep wash water out of storm drains.

2. Stormwater discharge compliance for pressure washing (Hartford)

   Pressure washing wastewater carrying detergents, oils or other pollutants may not be allowed to enter storm drains. Hartford is covered by CT DEEP's MS4 general permit, which requires the city to prohibit illicit non-stormwater discharges to its storm sewer system. Operators are expected to contain wash water - berms, booms or vacuum recovery - and dispose of it to the sanitary sewer or another approved receiving point. There is no Hartford County Environmental Health department to contact: Connecticut abolished county government in 1960, so questions go to the City of Hartford's Department of Health & Human Services Environmental Health division or Public Works, or to CT DEEP.

3. Hartford Trade Name (DBA) Certificate

   If you operate under a trade name, file a Trade Name Certificate with the Hartford Town & City Clerk before taking jobs under that name. Connecticut has no county government, so there is no county clerk; CGS Sec. 35-1 puts the filing with the town clerk. The application must be notarized, and two forms of identification are required if you sign it at the clerk's office.

   $20 filing fee; $5 to have it notarized at the clerk's office; $3 per certified copy·Filed in person at the Town & City Clerk's office
