Why it may be your responsibility
Building and zoning enforcement generally focuses on the condition of the property. Even if you had no part in the work, the authority will typically look to the current owner to resolve it. Whether you have any claim against a seller, agent, or inspector is a legal question for an attorney, and is separate from resolving the violation.
Piece together the history
These records can help establish what was done and when:
- Permit history from the local building department
- Your purchase documents, seller disclosures, and home inspection report
- Prior listing photos or appraisal reports
- Any plans, receipts, or warranties left by the previous owner
Options commonly available
Depending on the jurisdiction and the work, the options may include legalizing it through a permit for existing work, modifying it to meet code, or removing it. A design professional may need to document what exists, and inspectors may need to see concealed work.
Before you sell
If you plan to sell, addressing known unpermitted work early can reduce surprises during the transaction. Disclosure obligations vary by state; ask your real estate attorney or agent what applies.
