Summary
Cambridge lets residents run operator-occupied short-term rentals only while the operator actually lives there. If the host leaves the unit for more than seven straight days, the rental can no longer be split among separate short-term renters by bedroom.
An operator-occupied short-term rental during which the operator is away from the dwelling unit for more than seven (7) consecutive days may be rented only as a whole unit to one party of short-term renters at any one time and not rented as separate bedrooms to separate parties.
Full Breakdown

Violations & Fines
Renting bedrooms separately to different parties while the operator is away more than seven consecutive days breaches Section 4.64, item 9. Because the requirement is tied to the operator's certificate of registration under Section 4.67, the Inspectional Services Department can treat a violation as grounds to deny renewal or revoke the certificate; renting without a valid certificate is a separate zoning violation under Section 4.64, item 2.
