Key Takeaways
- The property owner bears primary responsibility for code compliance
- Contractors who fail to pull permits may be liable for all resulting costs
- Sellers who fail to disclose known unpermitted work are liable to buyers
- Real estate agents have independent disclosure duties
Property Owner Responsibility
Under California building codes, the property owner is ultimately responsible for ensuring all construction complies with local codes and has proper permits. The code enforcement notice goes to the owner, fines are assessed against the owner, and the owner must bring the property into compliance.
Contractor Liability
Licensed contractors have a professional obligation to obtain required permits. When a contractor fails to pull permits, they may be liable for breach of contract, professional negligence, violation of the Contractors State License Law, and all costs the owner incurs to bring the work into compliance. Under BPC §7031, if the contractor was unlicensed, the owner may recover all compensation paid.
Seller Liability
California sellers who know about unpermitted work and fail to disclose it are liable to buyers. Claims typically include the cost of bringing work to code, loss of property value, and in cases of intentional concealment, additional damages.
Real Estate Agent Liability
Under California Civil Code §2079, the seller's agent has a duty to conduct a reasonably competent visual inspection of the property. If unpermitted work would have been apparent to a careful agent, the agent may share liability.
Multiple Parties — Multiple Claims
In many situations, liability is shared. A homeowner who discovers unpermitted work done by a contractor hired by a previous owner may have claims against both the previous owner (failure to disclose) and the contractor (failing to obtain permits).

Is the homeowner or contractor liable for unpermitted work?
The homeowner is responsible for bringing the property into compliance, but the contractor who failed to pull permits may be liable for all resulting costs. Both parties can have separate legal obligations.
Can a previous owner be sued for unpermitted work?
Yes, if they knew about it and failed to disclose it during the sale. Claims for non-disclosure typically must be brought within 3 years of discovery.
Are real estate agents liable for undisclosed permit violations?
Under California Civil Code §2079, agents have a duty to conduct a visual inspection. If unpermitted work was reasonably discoverable, the agent may share liability with the seller.
