Hey Scott,
Here is the link to the San Diego County Assessor,s office.
https://arcc.sdcounty.ca.gov/Pages/parcelmaps.aspx
They charge $2.00 per page in TIFF format. I always buy the property characteristics at the same time which is another $1. This gives me info what the County has on record for number of bedrooms and baths and square footage of the house. Which has saved me a few times when the previous owners have added living area without a permit and I catch way before the design phase of the project.
And-- I know we still need to meet for lunch.
