The PNW has more boathouses than other areas, but also more boathouse fires.
Pretty much all individual boathouses in the PNW are wood structures with sheet metal roof and sides.
Open boatsheds housing multiple boats are now constructed from steel framing. Many older ones have wood framing.
There are not many rules for boathouse construction here in the PNW. Permits are required but are mainly for revenue. Here in Port Orchard, WA, the city require a permit but does not perform inspections when the boathouse is finished.
Department of Fisheries require 25% of the roof be translucent to allow fish some daylight even though fish usually like shadowed areas.
The majority of covered moorage fires are under sheds housing multiple boats, with no walls between the boats. Not many fires with individual boathouses housing one boat each.
We had a multiple boathouse fire at our YC a few years ago. 5 or 6 boats in individual boathouses burned and sank. Fire Marshall said that if the boats had not been separated by the metal boathouse walls, more boats would have burned.
