Full Breakdown
Sec. 6-152(c) sets a cumulative fee schedule that separates owner-occupied, seasonal, tenant-occupied, and island short-term units from non-owner-occupied mainland units, with fees rising per unit registered by the same owner: owner-occupied and similar units run $100 for the first unit, $250 for the second, $500 for the third, $1,000 for the fourth, and $2,000 for the fifth, while non-owner-occupied mainland units run $200, $500, $1,000, $2,000, and $4,000 for the same tiers. The fee total counts owner-occupied, tenant-occupied, and island rentals first, then applies the higher non-owner-occupied rate to remaining units.
Sec. 50). A long-term rental, by contrast, costs a flat $55 per year under Sec. 6-152(b), of which $30 is earmarked for the Housing Safety Office's Rent Board administration. All fees must be paid in full before a unit is considered registered, and Sec. 6-153(e) caps any individual or entity at five registered short-term rental units citywide per calendar year.
Violations & Fines
Sec. 6-152(e) imposes a $50-per-unit late fee for registrations not received by January 15 (or 14 days after entering the market, whichever is later), rising to $200 per unit if not received by February 15 (or 45 days after market entry). Registrations cannot be renewed until any late fee is paid, though the Permitting and Inspections Director may waive a late fee for hardship and good cause.
