Home Inspection in San Jose, CA
5 findings that come up most often in San Jose homes — assessed by a former builder who knows what this housing stock hides.
San Jose spans bay-adjacent flats, central valley floor and eastern and southern foothills. Soil behaviour, drainage priorities and typical construction era all shift substantially across those zones.
That shapes what a home inspection in San Jose actually needs to look for. Expansive soils in the foothill neighbourhoods is the finding that comes up most often here, followed closely by unreinforced chimneys and cripple walls. Both are specific to how San Jose was built and where it sits — not items from a generic checklist.
Everything from pre-1920 downtown and Willow Glen homes to 1950s–60s central tracts, 1970s–80s foothill development in Almaden and Evergreen, and extensive recent infill.
Local Findings
What comes up most in San Jose
These are the findings this inspection is actually looking for here — drawn from how San Jose was built and where it sits, not a generic list.
Expansive soils in the foothill neighbourhoods
Parts of Almaden, Evergreen and the eastern foothills have clay soils that shrink and swell seasonally. This drives foundation cracking, sticking doors and hardscape movement, and distinguishing seasonal from progressive movement is the key judgement.
Unreinforced chimneys and cripple walls
Pre-war Willow Glen, Rose Garden and downtown homes commonly have both. They are significant seismic findings and both have well-understood retrofits.
Unpermitted additions and converted space
Widespread across the city. I inspect what is there and flag egress, headers, ventilation and apparently unpermitted electrical or heating work.
Aging original plumbing in central tracts
Galvanised supply and cast-iron waste in 1950s and 60s housing are at end of life. Functional testing under simultaneous load reveals more than visual inspection.
Hillside drainage and retaining walls
In the foothill neighbourhoods, undrained retaining walls and runoff directed toward structures are the root cause behind most moisture and movement findings.
San Jose housing stock that matters here
Age and construction era change what this inspection prioritises.
1900s–1930s Willow Glen, Rose Garden & downtown
Bungalows and period homes. Expect unbraced cripple walls, unreinforced masonry chimneys, knob-and-tube remnants, and original clay sewer laterals.
1950s–60s central tracts
Cambrian, Blossom Valley and West San Jose. Galvanised supply piping, cast-iron waste, undersized electrical services and original windows are standard.
1970s–80s foothill development
Almaden Valley, Evergreen and Silver Creek. Priorities shift to site drainage on sloped lots, retaining walls, decks, and expansive soil movement.
2000s–present infill & attached housing
Concentrated downtown and along transit corridors. Emphasis on envelope detailing, balcony waterproofing and unit-boundary systems.
