An educational Board comparison for North Sound homeowners weighing a second-story addition against a full teardown-and-rebuild. Not a cost guarantee, appraisal, or structural opinion.

What you are really choosing

A second story keeps the existing footprint and neighborhood pattern but asks the current foundation, lateral system, and roof to carry new loads. A teardown resets systems and often zoning interpretation — and usually means longer vacancy, more demolition waste, and a full new-home permit path.

Neither path is automatically “better.” Good stewards compare habitability during construction, permit jurisdiction, engineering scope, and written exclusions before chasing a single headline number.

Official permit orientation: permit hub. Contractor verification: WA L&I Verify.

Decision checklist

  • Confirm parcel jurisdiction (city vs county) before concept drawings freeze.
  • Ask whether existing foundation and lateral systems were evaluated for added story loads.
  • Price temporary living, storage, and weather protection as first-class line items — not afterthoughts.
  • For teardown: confirm demolition, haul-off, and any asbestos/lead survey expectations in writing.
  • For second story: demand a written dry-in / temporary roof plan before openings are cut.
  • Shortlist firms with permitted local addition or custom-home experience; L&I Verify each legal name.

Second story vs teardown FAQ

Is a second story always cheaper than a teardown?

Not always. Structure, foundation capacity, roof complexity, temporary housing, and permit path can erase an apparent savings. Compare written scopes — not vibes.

Do I need engineering either way?

Often yes for second-story loads and for new foundations after teardown. Your AHJ and structural engineer set the bar; the Board does not invent stamp requirements.

Who should I hire first?

Shortlist design-build or addition specialists from Board directories, re-verify at WA L&I, then walk Site Visit Checklist questions before deposits.
