Development Costs

New Construction or Additions


For new commercial buildings, new single family residential homes, any additions, decks, and new accessory buildings, the permit cost is based on the square footage and type of construction of the project. You may download a fee quote form and email it to Permit Services at permitsvcs@bothellwa.gov. We will complete your fee quote and return it to you within one week of receiving the request.

Remodels


For tenant improvements, single family remodels not adding square footage, signs, commercial re-roofs, portable structures, detention vaults, retaining walls and personal wireless buildings, the permit cost is based on the valuation of the project. Sign permits and retaining walls require a separate valuation for each. The cost of the project, including tax, determines the valuation.
