Tips

  • Basement finishes are billed at $45/sq ft under the City's own Construction Valuation Calculator Schedule if that figure exceeds the ICC Building Valuation Data table result — confirm which valuation method applies to your project before budgeting.
  • Multi-family additions/remodels carry a materially heavier submittal list (24x36 site plan, HOA approval letter, water share certificate) than single-family — confirm your property type's document set with the Building Department before assembling plans.
