[quote author="bkshopr" date=1252724764]The very first front courtyard tract house plan in Orange County. An "L" shape plan does not qualify to define a courtyard by just 2 walls. (U shape plan)</blockquote>
The Vineyards in Foothill Ranch and Coronado in Aliso Viejo was some of the first courtyard style townhomes attached and Los Abincos in RSM was the first courtyard detached condo project that had a common courtyard. All of these homes the courtyard was where the garages where and a common driveway. These where all built in the early to mid 90's. But that is my guess as there could have been something built before. I think that is the question your asking but if i am off explain further what you are asking.
