Notes & caveats
From Lakewood handout B10: "Remodel – Changing the interior space of an existing structure, either structural or nonstructural, but not creating any new floor area." Two tiers exist: Major (structural design plans + calculations, life safety, change of use, accessibility) and Minor (moving non-load-bearing walls, anchorage moves, glazing/insulation, heating equipment). Basement habitable conversion typically falls under Major remodel.
