[quote=The-Shoveler]In California, the new homes are generally built to much high standards than the tract homes built from the 60’s to the 90’s.
Also there is generally much better work done on the lot preps then there were in the 60’s and 70’s.
Some old custom built and such are still a find however.[/quote]
Perhaps, Shoveler, but bear in mind that the tracts built in the 00’s often have 12 or more SFR units to an AC as opposed to the ’60’s to ’90’s tracts of 3-10 SFR units to an AC.
The time spent “precision grading” a group of subdivided parcels is proportional to how many separate pads and thus “elevations” (for homes) will be built on it. In the ’00’s, this was frequently “zero lot lines” or six feet apart for a new home costing the same as their ’60’s to ’90’s counterpart (with a 7500 sf lot).
