Some of the most valuable data are the permit applications. You may want to know about electrical or plumbing upgrades or the replacement of a roof. The permits may tell you whether that garage that has been converted into an apartment is legal. Sure, the sellers are supposed to disclose all these things. But do you think they do? The city of Portland, Ore., packs its site, www.portlandmaps.com, with this sort of information
Glad to see the team over at PortlandMaps get some more recognition for their great work. Any city, large or small should use their site as a benchmark on how to provide spatial information to their citizens.
