There are at least three resources for records on real estate properties in Eugene (though there could be more as well). These three are

Eugene City Records
Lane County Records
Eweb Records

Eweb is the local electricity, water, and sewage provider.

Useful links for public information

There are a couple of things to check, these include any open permits at either the county or the city, an closed permits (to know what improvements were actually permitted), past ownership of the property and what was paid for the property (sales history), any deed restrictions, and any social history of the property.

One way to indirectly evaluate contractors is to look at their closure rates on city permits. That is, how many permits have they successfully closed and is that typical for a contractor? How many have they left open?
