Where to find historical building lot maps over the last 20 years?
I am looking for housing plots and the corresponding development for say 5 year intervals since 1980 for an area in Orange County California.
When I was in Boston for research there was a company that did v good lot maps way back to the 1950's but I forgot the name of the company and whether they did work outside of Boston.
our sanborns all the way back to the mid/late 1800s are all in the city and county archives. not only are they archived for each ten year update, they modified them during the in-between years, collaging the changes onto the maps. beautiful documents.
sanborns are def your best bet - wherever you find 'em.
If you know anyone with a Berkeley IP address you can get Sanborns from their web site. link
Assesor's parcel maps will show lot lines, but not building footprints. You might find something in one of the many links from this page: Orange County GIS

I just called up Sanborn but they were closed for the day.
If anyone knows of other companies or sites please let me know.
Thanks
sanborn is my first thought.
not that i'd expect they'd likely part with the info, but perhaps the irvine company may have some of that data??
I'd check the public library of whatever municipality you're looking, as well as city hall and/or county hall.
Sanborn collections at local university? Archives dept?

1980s ain't historical unless you were born after then.
A great resource for historic maps from around the world is the Perry-Castañeda Library Map at UT. best of all, its free!
Main branch of your city's library.
the local planning department probably has aerial photos at intervals over the last 50 years. In my city, you can get access to them online.

Do Sanborns go as recent at the 1980s? I was under the impression that they stopped surveying in the '50s.
Spark's suggestion about local aerial-othros is a good one. These are more common, and usually updated every few years.
how about hysterical lot maps?
