One of the most common questions we hear from San Diego homeowners is: "Do I really need a permit for that?" The short answer is: if you're doing significant work, almost certainly yes — and here's why it matters enormously.
Why Permits Matter in San Diego
Resale disclosure requirements: California requires sellers to disclose all known unpermitted work. Buyers and their inspectors will find it. Unpermitted work discovered during a sale can derail escrow, force remediation at the seller's expense, or reduce the sale price by far more than the permit would have cost.
Homeowner's insurance: Many insurers void coverage for damage originating from unpermitted work. A fire traced to unpermitted electrical wiring can result in a denied claim.
Safety: Permits exist because building codes save lives. Structural failures, electrical fires, and plumbing disasters are vastly more common in unpermitted construction.
