Rancho Santa Margarita was developed on former Rancho Mission Viejo land and incorporated in 2000. Most homes were built between 1990 and 2005 as part of a master-planned community with a town center, lake, and extensive parks and trails. The city quickly became one of South Orange County's most desirable family communities.
At 20 to 35 years old, RSM homes have copper supply and ABS drain systems in generally good condition. But original water heaters are failing, angle stops are corroding, and hard water has had two to three decades to build scale. These are the plumbing needs we address most often in RSM.
