After-the-Fact Permits and Unpermitted Work
Unpermitted work is common, but it should be handled carefully. The goal is to understand the scope, safety risk, and local process before opening walls or scheduling contractors.

Start with facts
- Identify who performed the work, when it was done, and what systems were changed
- Gather photos, invoices, plans, inspection stickers, product labels, and contractor names
- Do not cover or disturb suspect work until you understand the inspection path
Common local paths
- Some offices allow an after-the-fact permit with drawings, inspections, and correction work
- Some require licensed professionals to evaluate structural, electrical, plumbing, or mechanical work
- Some work may need selective demolition so inspectors can see concealed conditions
When to get help
- Structural changes, gas piping, electrical panels, fire damage repairs, additions, ADUs, and finished basements deserve professional review
- Real estate transactions and insurance claims can raise disclosure and documentation issues
- Ask the local office what documents they need before you apply
