alt Hacker NewsA justification for this would be: states choose these providers to accurately present building codes (keeping up with the right versions/revisions is a lot of work, etc) because there's risk in simply publishing the PDFs and leaving it to basically anyone to curate. But the providers (like ICC) also tend to lock these deals in with state laws (not sure if they lobby for it, but I would imagine they do). When you think about who needs to have access to the correct and current building code or electric code or whatever for regular reference, it's really your lawyer, plumber, electrician, architect, builder, etc. and in that context $170 or $130 isn't a bad deal.
It also locks up things for homeowners that want to DIY a solution fixing a house. Obviously people fix things without looking at the codes (and there are plenty of horror stories out there), but if we opened up house codes for people to actually look at and refer to, homeowners could potentially better find how to do things properly, especially with AI.
