Key Takeaways

• When a contractor’s work fails a city or county inspection, the contractor is generally responsible for correcting the work so it passes, at no extra cost to you, if the failure resulted from their work.
• A failed inspection can be legitimate grounds to withhold payment for the work that did not pass, used carefully and in writing.
• Unpermitted work is its own serious problem. If a contractor pulled no permits, the work may have to be corrected, re-done, or retroactively permitted, and that can fall back on you as the property owner.
• Unpermitted or non-conforming work can create real headaches when you try to sell or refinance, including disclosure obligations and lender or buyer concerns.
• A contractor who failed to pull required permits or whose work repeatedly fails inspection may have exposure both to you and to the licensing board.

Contractor Failed Inspections in California: Who Is Liable and What Comes Next?

A failed inspection is the system working the way it is supposed to: an independent set of eyes catches work that does not meet code before it gets buried behind drywall or becomes a safety hazard. But for a homeowner, a red tag or a failed inspection raises immediate, practical questions. Who has to fix it? Do I still owe the contractor? And the more unsettling discovery that sometimes follows, what if the contractor never pulled permits at all? The answers generally favor the homeowner, but only if you understand the landscape.

Who is responsible when work fails inspection?

Building inspections exist to confirm that work meets the applicable codes and the approved plans. When work fails because it was not done correctly, the contractor who performed it is generally responsible for bringing it up to standard so it can pass, and generally without charging you extra to fix their own deficient work. You contracted for work that meets code; work that fails inspection because of how it was built generally does not meet what you paid for.

There are nuances. An inspection can fail for reasons that are not the contractor’s fault, an unforeseen condition, a plan issue, or a code interpretation question. And on projects with multiple trades, the failure might trace to a particular subcontractor’s scope. But as a starting point, when a contractor’s own work does not pass inspection, fixing it is generally their problem to solve, not an extra you should have to fund.

Can you withhold payment over a failed inspection?

Often, yes, for the work that failed. A failed inspection can be legitimate grounds to withhold payment tied to the deficient work, on the same principle that runs through these disputes: you generally owe for work properly performed, and work that fails inspection because it was done wrong is generally not yet properly performed.

As always, the way you do it matters. Withhold payment specifically for the portion of work that failed, not for unrelated work that was done correctly. Put your position in writing, referencing the failed inspection and what needs to be corrected. And keep the inspection records, they are strong, independent documentation that the work fell short. Used this way, withholding is a defensible response. Used as a blanket refusal to pay anything, it is weaker. We cover the mechanics of withholding in our article on a contractor demanding full payment, which pairs naturally with this one.

The bigger problem: unpermitted work

Sometimes the discovery is not just a failed inspection but the absence of any inspection, because the contractor never pulled the required permits in the first place. This is a more serious situation, and it has consequences that can land on you as the owner.

Most significant construction work requires a permit, and permitted work gets inspected at defined stages. When a contractor skips permits, several problems follow. The work was never independently verified, so its quality and code-compliance are unknown. If the local building department discovers unpermitted work, it may require that the work be exposed for inspection, corrected to meet current code, retroactively permitted, or in some cases removed. And because permits attach to the property, these consequences can fall on you, the owner, even though the contractor created the problem.

A contractor who was responsible for obtaining permits and failed to do so may bear responsibility for the resulting costs and complications, and unpermitted work can also be a licensing issue that exposes the contractor to discipline. But practically, you are often the one left dealing with the building department, which is why discovering unpermitted work is worth taking seriously and addressing rather than ignoring.

What unpermitted work means when you sell or refinance

This is where unpermitted work tends to bite hardest, often long after the project is over. When you sell a home in California, you generally have obligations to disclose what you know about the property’s condition, and known unpermitted work or non-conforming improvements can fall within that. Failing to disclose problems you are aware of can create its own liability in a sale, a topic that overlaps with real estate disclosure rules.

Beyond disclosure, unpermitted work can complicate a sale or refinance in concrete ways. A buyer’s inspector may flag it, a buyer may demand that it be permitted or corrected before closing, an appraiser may not credit unpermitted square footage, and a lender may raise concerns. What felt like a way to save time and money during the project can resurface as a discount, a delay, or a deal problem years later. If you are aware of unpermitted work on your property, it is far better to understand and address it on your own timeline than to have it surface in the middle of a transaction.

When to get help

A single failed inspection that the contractor promptly corrects may never need a lawyer. But the situation deserves a closer look when the contractor refuses to fix work that failed, when work repeatedly fails inspection, when you discover the contractor pulled no permits, or when unpermitted work is complicating a sale or refinance. In those situations, understanding your rights against the contractor, and your obligations as an owner, can save you significant money and risk.

The bottom line

When a contractor’s work fails inspection, fixing it is generally their responsibility, and you can often withhold payment for the deficient work if you do it carefully and in writing. Unpermitted work is a bigger and longer-lasting problem, one that can fall on you as the owner and can complicate a future sale or refinance through disclosure obligations and buyer or lender concerns. The contractor who created the problem may bear responsibility, but you are often the one who has to resolve it, so the sooner you understand where you stand, the better.

Frequently Asked Questions

Who is responsible when a contractor’s work fails a city inspection in California?

When work fails inspection because it was not done correctly, the contractor who performed it is generally responsible for bringing it up to standard so it passes, and generally without charging extra to fix their own deficient work. There are exceptions, an inspection can fail for reasons outside the contractor’s control or trace to a particular subcontractor, but a contractor’s own non-conforming work is generally theirs to correct.

Can I withhold payment from a California contractor whose work fails inspection?

Often, yes, for the portion of work that failed. The principle is that you generally owe for work properly performed, and work that fails inspection because it was done wrong is generally not yet properly performed. Withhold specifically for the deficient work, put your position in writing referencing the failed inspection, and keep the inspection records as independent documentation.

What happens if unpermitted work is discovered after a project is completed in California?

If a contractor skipped required permits, the local building department may require that the work be exposed for inspection, corrected to meet current code, retroactively permitted, or in some cases removed. Because permits attach to the property, these consequences can fall on the owner even though the contractor created the problem, though the contractor may bear responsibility for the resulting costs.

How does a failed inspection or unpermitted work affect my ability to sell or refinance my California home?

Unpermitted or non-conforming work can complicate a sale or refinance. When selling, you generally have obligations to disclose known property conditions, which can include unpermitted work. A buyer’s inspector may flag it, a buyer may demand it be permitted or corrected before closing, an appraiser may not credit unpermitted square footage, and a lender may raise concerns. Addressing it proactively is generally better than having it surface mid-transaction.

What are my legal options when a California contractor pulls no permits and the work is substandard?

A contractor responsible for obtaining permits who failed to do so may bear responsibility for the resulting costs and complications, and unpermitted work can expose the contractor to licensing discipline. Your options may include pursuing the contractor for the cost to correct and properly permit the work, and addressing the building department’s requirements. Because you as the owner are often left resolving it, getting the situation evaluated helps clarify your rights and obligations.
