A footing near a slope has to be placed before it is dug. The California Residential Code draws a line down from the face of a descending slope, one third of the slope's height back and never more than 40 feet, and a footing inside that line either moves back from the slope or goes deeper until its bottom clears it. On a Mission Viejo pad the slope starts a few feet past the rear fence and the back of the pad is fill, so a footing there is very often both moved and deepened.
Saddleback Mission Viejo Concrete pours footings for the room additions, patio covers, ADUs, pool equipment pads and walls that a house built between the mid 1960s and the 1990s asks for in time. Trevor Lindqvist digs the test hole at the estimate himself, because the depth of fill at the back of a pad is not on any drawing, and the crew that opens the trench is the crew that ties the steel and meets the inspector. Where an engineer has drawn it, it is built to the sheet.
Footings are built to the California Residential Code under a CSLB C-8 concrete license, with liability insurance on every job. Anything carrying a structure takes a building permit from the City of Mission Viejo's Building Division, and the trench is inspected open, steel in, before a yard of concrete is ordered. Most associations also want to approve what stands on it. The finished footing has a written workmanship guarantee against defects in how it was built.
