Construction & Remodeling in Bellingham, WA

Bellingham work can include ADUs, infill housing, remodels and re-roofs in Whatcom County's marine climate zone. City rules allow up to two ADUs per lot, and re-roof permits are applied for online, so project type and zoning shape the plan early.

What shapes a project in Bellingham

Local conditions worth knowing before scope and budget are set.

  1. Up to two ADUs per lot

    Bellingham allows up to two accessory dwelling units per lot, attached or detached, each up to 1,000 square feet. ADUs can be a converted garage, a unit in an attic or basement, or an addition to the house.

  2. Interim infill rules

    Interim regulations that took effect December 23, 2025 allow infill housing of up to six units per lot in areas zoned mainly for residential use, except in the Lake Whatcom Reservoir area. The city lists them as in effect until December 4, 2026, so check the current rules before design.
