Starting June 19, nail salons, tattoo studios, body waxing and other personal services are allowed to reopen in San Bernardino County with modifications. These are among several Stage 3 businesses and activities the state Department of Public Health is allowing to reopen in counties like ours that have met certain thresholds on number of cases, testing and preparedness.
The state has issued guidance documents on personal services here: https://covid19.ca.gov/pdf/expanded-personal-services.pdf
Small businesses that need assistance complying with the guidance should look into the San Bernardino County COVID Compliant Business Partnership Program, https://sbcovid19.com/covid-compliant-business-partnership-program/. Participating small businesses can receive up to $2,500 in funding to pay for improvement, equipment, and supplies needed to comply with safety guidance.
