if you ever need to have your house inspected (say you're buying insurance, or a tree falls through it, etc) they'll compare it the wood stove that's listed in the details of your last house inspection. if it looks like you installed an old stove after the ban they'll probably fine you and maybe even refuse to insure you until it's removed.
i have to admit you're right. however, it really isn't such a huge burden. i look at is being similar to our country's building codes. you know, you can't build an old european-style house or building out of unreiforced masonry and expect to have it insured. we have to build with wood and steel because of earthquakes.
now you can build a brick cottage and put an old wood stove in it and go off grid and you won't have any problems. but it won't ever be a legit residence.
i know it seems that way but we really want people to respect and protect the environment. this is a pretty unique place and if it seems like we go overboard sometimes it's only because the local nature evokes those types of feelings in us.
a temperate rainforest with mountains and volcanic mountains, endless rivers, densely green, the most oldgrowth forests, trees like skyscrapers, bears, mountain lions, clams the size of basketballs, salmon that practically throw themselves into your kitchen, all beneath the waves of the world's greatest ocean ...
yep. and also most properties you'll find are protected wetlands, so ... not uncommon to have a 20 acre property and only be able to legally build in a little half-acre square ...
this is if you want to go the legal route and have house insurance and all that stuff. if you just want to live in WA, buy a piece of recreational property, put a cabin on it, put an old $200 wood stove in it and live in the thing off the grid and under the radar. pretty typical in this region.
