Unpermitted Structural or Foundation Work
Unpermitted structural work — including foundation modifications, load-bearing wall removal, and seismic upgrades — is among the most serious violations because it directly affects building safety and stability. Resolution typically requires engineering review.
Is This a Permit Violation?
If the work was done without required permits, it is a code violation regardless of quality. The question is not whether the work is good — it's whether it was inspected and approved by the building department.
What to Do
- Contact the building department to determine whether permits were obtained
- Evaluate whether after-the-fact permits are available
- Get estimates for any correction work needed
- If a contractor did the work without permits, pursue them for compliance costs
- Consult an attorney if costs are significant or liability is unclear

What is considered structural work requiring a permit?
Any modification to load-bearing walls, foundations, floor joists, roof trusses, or other structural elements. Adding or removing walls, enlarging openings, and seismic retrofits all require permits and engineering.
How serious is unpermitted structural work?
Very serious. It directly affects building safety and stability. Unpermitted structural work often requires engineering review, may need significant corrections, and creates substantial liability.
Can unpermitted structural work collapse my house?
Improperly executed structural modifications can lead to foundation failure, wall collapse, or roof failure. This is why structural work requires engineering review and building department inspection.
