I am trying to find blueprints for my house in Altadena CA?
Answers:
Unfortunately, this is a common situation. Usually, the only people who get blueprints for their homes are people who have contracted a builder to build a custom home. It is unlikely that you will find the prints that you seek. Most building inspectors offices do not keep plans on file much past a year after a home is completed and a Certificate of Occupancy has been issued. They simply would be overwhelmed by the plan files in all but the smallest towns. I also do not know of any offices that scan the files due to the expense involved.
I have bought and sold a lot of property over the years, and I have yet to see an architect identified on a deed. The identity of the architect is not necessary to transfer ownership of real estate.
Have you thought about hiring the services of a real estate inspector? It should be fairly easy to identify the alterations to your house. Since this would not be the type of full blown inspection you would get if you were buying a used home, I'll bet you could get an opinion in an hour for somewhere around $150.00. You might get it cheaper if the inspector is located close to you.
To find an inspector in your area, why not try the Yahoo yellow Pages:
