Summary
Bellingham lets homeowners skip a building permit for a small prefabricated above-ground pool, but only if it stays under 24 inches deep and holds no more than 5,000 gallons.
105.2 Work Exempt From Permit... Permits shall not be required for the following: ... 11. Prefabricated swimming pools accessory to a 1- and 2-family dwelling or Group R-3 occupancy which are less than 24 inches (610 mm) deep, do not exceed 5,000 gallons (18,925 L) and are installed entirely above ground;

Full Breakdown
The Building Division's Construction Administrative Code lists prefabricated above-ground pools among the narrow set of projects that don't need a permit, but the exemption is tight: under 24 inches deep, 5,000 gallons or less, installed entirely above ground, and accessory to a one- or two-family home or Group R-3 use. Anything deeper, bigger, or dug into the ground falls under the adopted 2021 International Swimming Pool and Spa Code and needs a full Building Division permit before installation, the same as any other Bellingham, Washington structure in Whatcom County.
Violations & Fines
Installing a pool that exceeds the exempt thresholds without a permit is a Construction Administrative Code violation: a civil infraction up to $2,050 (minimum $100), or a gross misdemeanor up to $5,000 and 364 days if done knowingly.
