Pasco, WA Short-Term Rentals: Night Caps (2026)

Pasco does not regulate short-term rentals through an annual cap on rental nights the way some cities do (for example, a 90- or 180-night ceiling). Instead, the city draws a bright line at length of stay: its FAQ states that Pasco does not allow short-term rentals under 30 days. That 30-day minimum is the controlling number, and it is more restrictive than a night cap because it bars the short-stay use entirely rather than limiting how many nights it may occur. For accessory dwelling units, the code adds duration-based requirements that point the same direction: PMC Chapter 25.161 requires that an ADU be used for long-term residential purposes, that residents live there more than 180 days each calendar year, and that the ADU not be used for transient occupancy or short-term/vacation rental. So the only day-count figures in play are the 30-day minimum stay that defines a transient/short-term rental and the 180-day minimum residency that an ADU occupant must meet - both of which work to exclude vacation-style rentals rather than to permit a capped number of them. This entry does not cite an annual rental-night cap, because Pasco does not impose one; the binding rule is the prohibition on stays shorter than 30 days.
