There’s been a spike of recent interest here on the blog about original construction dates and early builders, which is great. Every house has an origin story all its own and they’re always interesting. I’m currently working on profiles of several more builders to join the 25 already in The Builders section, and I’ve appreciated the suggestions from readers about who to focus on next.

Thinking about these things, I am reminded about the study of building inspection cards I did a few years back which really helped me understand geographic patterns of growth, Portland’s early waves of expansion and recession, and a very busy group of early homebuilders.

On many evenings over two years in the mid-2000s, I was granted research access behind the counter at the Bureau of Development Services to examine construction inspection cards. Slowly and carefully, I handled every inspection card in the Alameda Park addition and noted details into a growing record. While my scope of interest is much wider than just Alameda, it’s hard to boil the ocean so I had to define the boundaries of the search. The thought of recording details from every eastside inspection card (by hand) is overwhelming.

Back in 2010, I posted a summary of that research here on the blog. Because AH is up to about 300 posts since 2007, it’s possible current readers haven’t seen it. I realize that’s an ongoing challenge, by the way, of wayfinding through the content here (try using the categories feature, with drag-down menus which you can find on the far right edge of the blog).

So in the spirit of knowing more about how the Alameda neighborhood developed (where, when, who), have a look at insights from a survey of historic construction inspection cards.
