Summary
Unincorporated Snohomish County imposes no cap on rental nights. SCC 30.28.020(3)(f) states there is no limit on the number of days a guest may stay at the establishment. However, occupancy of one month or more is treated as a lease and falls outside the transient lodging tax.
There is no limit on the number of days a guest may stay at the establishment;
(g) The applicant shall submit a letter from the applicable water purveyor and sewer district, if applicable, stating that each of them has the respective capacity to serve the bed and breakfast establishment;
(h) The applicant shall comply with all applicable county codes for fire, health, and building requirements and any applicable food service regulations and on-site sewage disposal requirements of the county health department. The applicant shall comply with the applicable state regulations pertaining to public water systems, if a water system is to be developed or connected to an existing public water system;
(i) If three or more guest rooms are proposed, the applicant shall also meet state regulations pertaining to transient accommodation;
(j) If six guest rooms are proposed, the applicant shall meet all requirements for a hotel occupancy pursuant to the building code in chapter 30.52A SCC;
(k) If outbuilding(s) are proposed for guest rooms, each outbuilding shall be a minimum of 130 square feet. The aggregate outbuilding square footage for guest use shall not exceed 850 square feet; and
(l) If an accessory dwelling unit or temporary dwelling exists on the premises, the maximum number of bed and breakfast guest rooms shall be one less than otherwise permitted.

Full Breakdown
SCC 30.28.020(3)(f) expressly provides that "there is no limit on the number of days a guest may stay at the establishment," so the county does not impose annual night caps or minimum-stay requirements on a permitted bed-and-breakfast. For tax purposes, though, the lodging tax code (SCC 4.40.010 / 4.41.010) presumes that occupancy of a continuous month or more is a rental or lease, not taxable transient lodging. So while there is no operational night cap, stays crossing the one-month threshold change the tax treatment. City STR ordinances elsewhere in the county may impose their own annual night limits.
Violations & Fines
Because there is no county night cap, enforcement in this area focuses on permit and tax compliance rather than length-of-stay limits.
