Chapel Hill, NC Short-Term Rentals: Occupancy Limits (2026)

Chapel Hill's STR framework imposes occupancy as a use-standard condition of the zoning compliance permit issued under Ordinance-9 (June 2021), drawing on three operative legal layers. First, the LUMO definition of 'family' / 'dwelling unit' for residential zoning includes a 'no more than four unrelated persons' rule - a household-composition limit historically enacted in Chapel Hill (and many UNC-adjacent jurisdictions) to address student-rental density in single-family neighborhoods. The rule applies to the dwelling's lawful residential occupancy and, by extension, to the occupancy of an STR use within a dwelling unit; an STR cannot lawfully be occupied by more unrelated guests than the LUMO permits to occupy the dwelling as residents. For a typical investor-style Dedicated STR with guests who are unrelated to each other, this effectively caps occupancy at 4 in a single dwelling unit. The Local Reporter has noted that enforcement of this rule is challenging in practice but the rule remains the codified ceiling. Second, the Chapel Hill Housing Code (Chapter 9, related housing standards) and the NC State Building Code apply: each rentable bedroom must have a code-conforming egress (door to the exterior or egress window meeting NC State Building Code), smoke alarms must be installed in each bedroom and on each floor, CO detectors must be placed near sleeping areas in dwellings with fuel-burning appliances or attached garages per NC law, and minimum room sizes and sanitary facilities must be adequate for the occupancy. Third, the zoning compliance permit issued under Ordinance-9 may carry use-standard conditions specific to the property reviewed (typical-occupancy expectations, maximum-guest-count conditions where the dwelling's site or systems require). Common industry-norm formulas such as 'two persons per bedroom plus two' or 'two persons per bedroom' are not codified by Chapel Hill but are reasonable house-rule guidelines. Operators should size guest capacity to the lower of (a) the LUMO 4-unrelated-persons ceiling, (b) the dwelling's bedroom count under the industry-norm two-per-bedroom formula, and (c) any specific permit conditions or HOA covenant limits. The dwelling's water, sewer, and septic capacity should also be considered to avoid Housing Code complaints. Operators should not market non-bedroom rooms (basements without egress, dens, lofts) as sleeping space.
