FOUNDATION INSPECTION · SAN JOSE
Foundation Inspection in San Jose by PE Structural Engineers
Cracks in drywall, sticking doors, sloping floors, or a lender or buyer asking for a foundation report: a California-licensed PE structural engineer from Cecilia Home inspects the foundation on site and documents what we find in a written foundation inspection report. If repair is warranted, we prepare repair recommendations and stamped repair design plans for a San José building permit. We are a design and engineering firm, not a contractor; your chosen licensed contractor performs the repair work.

Local Foundation Conditions
San Jose Soil, Hazards & Repair Permits
San José sits on the floor of the Santa Clara Valley, where layered clay and sand deposits, a long history of groundwater-driven land subsidence, and nearby active faults all shape how foundations perform. State seismic hazard zones and City geologic hazard zones can also add review steps when a repair requires building plans.
Required
Permit for foundation repair
A building permit is required to repair or replace a foundation.
~14 ft
Historic subsidence, downtown San José
Caused by groundwater overdraft; permanent subsidence essentially halted by about 1970.
72%
Bay Area M6.7+ chance, 2014–2043
USGS regional forecast; Hayward, Rodgers Creek, Calaveras, and San Andreas faults rank highest.
PI ≥ 15 or EI > 20
CBC expansive-soil threshold
Where expansive soil is likely, the building official shall require soil tests.

What You Receive
San Jose Foundation Inspection Deliverables
Engineering documents only. We inspect, report, and design the repair; licensed contractors build it.
On-Site Engineer Inspection
A California-licensed PE structural engineer reviews accessible foundation elements, floor levels, crawl-space supports, drainage, and moisture conditions.
Written Inspection Report
Observed conditions, photographs, likely causes, and prioritized recommendations in one signed foundation inspection report.
Repair Recommendations
What needs repair now, what can be monitored, and whether a geotechnical investigation is needed before repair design.
Repair Design & Permit Plans
When repair is needed, calculations and permit drawings that licensed contractors can bid and the building department can review.
Share the address, what you have noticed, and how the report will be used (purchase, sale, insurance, or repair planning).
San Jose Foundation Risks
Why San Jose Homeowners Get an Engineer's Report First
A repair is only as good as the diagnosis behind it. An independent engineering inspection defines the cause and the scope before anyone prices construction.
Common Risks
Repairing without a permit or plans
San José requires a building permit to repair or replace a foundation, submitted with project plans through Standard Plan Review.
Unchecked hazard zones
A property in a geologic or seismic landslide zone needs a Geologic Hazard Clearance before the building permit, which can add geotechnical work.
Guessing at the cause of cracks
Settlement, soil movement, and drainage produce similar symptoms; a repair scoped without an engineering evaluation may address the wrong cause.
Our Approach
CA-licensed PE structural engineers
On-site inspection and a written foundation inspection report signed by a licensed engineer.
Design-only, no repair upsell
We do not perform repairs, so recommendations are independent of who builds the work.
Report to permit-ready plans
If repair is needed, we prepare repair design plans for San José Standard Plan Review and respond to plan check comments.

Licensed Engineering for San Jose Foundation Inspection
Is Your San Jose Foundation Inspection Team Backed by a Licensed Engineer?
Too many San Jose homeowners lose weeks or months on foundation inspection projects when engineering is incomplete or plans are not coordinated for City review. Unreviewed structural details can also create costly rework and real safety risks. Make sure a licensed Professional Engineer stands behind every structural decision.
Led by Lei Zheng, a California-licensed Professional Engineer since 2006, Cecilia Home identifies structural risks for foundation inspection projects in San Jose, prepares permit-ready calculations and drawings, and coordinates City plan-check responses—helping avoid preventable corrections, rework, and delays.

FAQ
San Jose Foundation Inspection Questions
Answers about San Jose foundation conditions, permits, and our design-only role.
Haven't found what you're looking for?
Yes. The City of San José states that a building permit is required to repair or replace a foundation. Foundation projects use Standard Plan Review: the application is filed at SJPermits, plans are uploaded through SJePlans, and the permit is issued after plan approval and fee payment.
A PE structural engineer documents the foundation type, observed cracking, settlement or movement indicators, likely causes, and recommendations, such as monitoring, further geotechnical investigation, or repair. If repair is recommended, we can prepare repair design plans for the San José permit submittal.
Enter the address on SJPermits.org; the City lists any flood, geologic hazard, or seismic landslide or liquefaction zone designations. If the property is in a geologic or seismic landslide hazard zone and the project includes building plans, a Geologic Hazard Clearance is required before the permit.
Historic groundwater overdraft caused about 14 feet of subsidence in downtown San José. Valley Water reports permanent subsidence was essentially halted by about 1970 and no permanent subsidence occurred during the most recent droughts. Older buildings may still show effects of past ground movement, and other causes such as soil moisture changes need site-specific evaluation.
Yes. CBC Section 1803.5.3 classifies soil as expansive based on plasticity index (15 or greater), fines content, or an expansion index greater than 20, and requires soil tests where expansive soil is likely. Your engineer may recommend a geotechnical report before repair design.
No. Cecilia Home is a design and engineering firm. We inspect, report, and prepare repair design and permit plans; a licensed contractor of your choice performs the repair. The City recommends that the permit applicant be a licensed contractor.
