Top 5 by ADU permits filed in the last 12 months. This is volume, not quality: a busy firm is not necessarily a careful one.
Before you move a slider, the list is in a default order built only from the permit record: how much of each firm’s record is this kind of job (weight 30), how often its permits reached completion (25) and how many permits it filed in the last 12 months (15). Each measure is ranked against the other 71 firms and pulled toward the middle when a record is short; a firm with a matched license problem is listed last.
The order comes from the Bellingham permit file, not from reviews: 33 of 71 ADU builders filed a permit in the last 12 months. Nobody pays to be listed or to move up, and there are no star ratings or reviews. The sliders and presets change the weights, and the order changes with them. How the records work in Bellingham.
