Protecting Your Property from Hidden Dangers
In many cities, including San Francisco, construction-related code violations are more common than you might expect. Some may seem minor, but even small violations can compromise safety, legality, and property value.
This page helps you recognize common types of building code violations—especially those related to outdoor additions like signs, awnings, and canopies—and what you can do when you suspect something is wrong.
Common Violations
1. Unpermitted Construction
• Work started or completed without a building permit
• Includes awnings, electric signs, staircases, decks, and additions
2. License Misuse or Identity Fraud
• A person uses someone else’s contractor license number
• Or claims to be licensed when they’re not
3. Improper License Classification
• For example: using an electrical license (C10) for sign work that requires a C45 license
4. Illegal Use of Owner-Building Permits
• Contractor instructs property owner to pull the permit to bypass license requirements
• Violates California contractor law and puts the owner at risk
5. No Subcontractor Disclosure
• Contractors fail to report their subcontractors as required
• Makes accountability difficult in case of disputes or inspections
6. Unsafe Installations
• Poor anchoring of signage or awnings
• Exposed wiring, fire hazards, or unstable supports
• Violates fire and structural codes
How to Spot a Violation
• No permit posted at the job site
• Contractor refuses to show proof of license
• Permit is filed under the owner’s name, but contractor is clearly doing the work
• Work is done quickly, at odd hours, or looks inconsistent with the neighborhood
• Unsafe appearance: loose cables, flimsy supports, obstructed exits
Why It Matters
• Legal liability: You, as the owner, may be held responsible for illegal work
• Insurance risk: Improper installations may void insurance coverage
• Injury hazard: Unsafe structures pose a serious threat to the public
• Code enforcement: Can result in fines, citations, or forced removal of the addition
What You Can Do
• Check all permits and licenses before work begins
• Ask your contractor for their license number and classification
• Report suspected fraud to your local building department or the CSLB
• Take photos of suspicious work for your records
