How to Save $10,000 on Your Attic Remodel
Well, it may not work for you, but it worked for us. Current Portland Building Code requires that stairs must be a minimum of 9 inches deep (run) and a maximum of 8 inches high (rise). Remodels like ours must also conform to this standard, unless they include an “Existing stairway that leads to existing finished living space that was created with a building permit (Verify prior permits at the Development Services Center).”
That last part is key. Because while our attic space was definitely liveable before we pulled down the vintage paneling, its stairs are more definitely non-conforming. Our run is anywhere from 8.25 to 8.5 inches, with an 8 inch rise, and a barely-noticeable nosing. This may not seem like much of a difference, but our estimates to bring the stairs into conformance started at a cool 10K, with structural changes that might have required re-designing the kitchen, attic stairs … you’ll pardon the pun if I call it a slippery slope.
But, we lucked out big time when we went down to the building office for the first time. You see, there was an existing building permit on file. A plumbing permit, anyway. (From 1927, even though we’d been told our house was built in 1928!). And if I may draw your attention to the line reading “Stories and Class of building,” you’ll see the magic words:
“new, fr. 1 1/2 sty dwg.”
Apparently, that’s old school builder-speak for “new one and a half story dwelling.” The second floor was intended as-built for living space, and its stairs for daily use. Hence, we are grandfathered in, by a probably now great-grandfather of a plumber working for Standard Plumbing and Heating Company in 1927. They’re still in business today, and now, so are we.
