Home Inspection in Rancho Cucamonga

Many newer tracts sit on post-tension slabs over expansive soil. We document foundation cracking, floor-flatness clues, door and window racking, and exterior grading and drainage, note the post-tension stamps and the no-cut rule for future work, and flag when a soils or structural engineer should weigh in. For our deep dive, see our Rancho Cucamonga post-tension slab guide.

On the higher ground in Alta Loma and Etiwanda, the home sits on or below alluvial fans where canyon runoff and debris flow are real. We check surface drainage, retaining walls, and grading, and flag what a geotechnical engineer should evaluate where the slope and findings warrant it.

The big stucco tracts hide water problems behind an intact finish. We check weep-screed clearance, cracking, and window and door flashing, and run thermal imaging to surface moisture that has gotten behind the stucco.

Concrete tile roofs look permanent but ride on underlayment that ages out in roughly twenty to thirty years, which many Rancho Cucamonga tracts have now reached. We document tile, underlayment clues, and flashing with drone imagery. For the detail, see our tile roof underlayment guide.

Production building moves fast, and inland summers are hot. We look for undersized or aging HVAC, water-heater and plumbing shortcuts, grading that drains toward the house, and the attic ventilation that matters in the heat.

Many homes carry leased or financed solar that must transfer cleanly, and most sit in HOAs. We report unpermitted additions and what is actually there, and flag the solar and HOA paperwork worth confirming early.
