California FTB Notice Substandard Housing Notification of Notice of Noncompliance (AUD 1578)

The AUD 1578 is a notification that the FTB has received a notice of noncompliance from a local housing authority about your property. Think of it as an early warning. The AUD 1576 comes later and is the actual demand to provide documentation proving compliance. The 1578 gives you a heads-up that an audit may follow if the underlying housing violation is not resolved.

Receiving the AUD 1578 does not automatically mean your deductions will be disallowed. It means the FTB’s data match system flagged your property address based on reports filed under Health & Safety Code Section 17920.10. You still have time to get the violations corrected and obtain clearance documentation from your local code enforcement office before the more serious AUD 1576 arrives.

We tell our clients at The Reed Corporation that the AUD 1578 is actually good news, relatively speaking. It gives you a window to fix the problem proactively. We help clients identify the specific violations cited, coordinate with local inspectors to schedule re-inspections, and document the corrections so the FTB audit never escalates.

Contact your local city or county code enforcement office immediately. Ask for the specific violation notice that the FTB references. Get the violation number, inspection date, and exact deficiencies listed. This information tells you precisely what needs to be fixed before the FTB follows up with a formal audit demand.

Start correcting the violations right away and keep every receipt and document. Hire licensed contractors, get permits where required, and schedule the re-inspection as soon as repairs are complete. Under California Health & Safety Code Section 17920.3, the local authority must re-inspect within a reasonable time after you notify them that corrections are done. Get the clearance letter or certificate of compliance in writing.

Bring the AUD 1578 to The Reed Corporation before you respond to the FTB directly. We review the underlying violation, assess whether your rental deductions are at risk under R&TC Section 17274, and create a compliance timeline. Our goal is to have your documentation package ready before the FTB even sends the follow-up AUD 1576.

Not exactly. The AUD 1578 is a notification letter, not a formal audit notice. It tells you the FTB is aware of a housing code violation linked to your rental property. A full audit under the FTB’s Substandard Housing Program begins when you receive the AUD 1576, which demands specific documentation and sets a firm response deadline.

That said, treat the AUD 1578 seriously. The FTB sends it because your property appeared in a local government noncompliance database. If you ignore it and the violation remains unresolved, the FTB will escalate. At that point, you are dealing with a formal audit that can result in disallowed deductions and additional tax assessments for every year the property remained noncompliant.

We advise our clients at The Reed Corporation to treat the AUD 1578 like a pre-audit opportunity. Resolving the issue at this stage is faster, cheaper, and less stressful than fighting a Notice of Proposed Assessment later. The FTB is far more cooperative when you address problems before they have to chase you.

The AUD 1578 itself does not set a hard deadline for correcting the violations. However, the local housing authority’s original noncompliance notice typically gives 30 to 90 days depending on the severity of the violation and your city’s municipal code. Check that local notice for the actual correction deadline because that is the clock that matters most.

From the FTB’s perspective, the key date is when you file your next tax return or when the FTB sends the follow-up AUD 1576. If your property is still noncompliant at that point, your rental deductions are at risk. The practical window is usually 3 to 6 months between the AUD 1578 and any formal audit action, but this varies by FTB workload and case priority.

The Reed Corporation helps clients create a repair and compliance timeline the moment the AUD 1578 arrives. We coordinate with your property manager or contractor to get corrections done fast, then document everything in a format the FTB auditor will accept. Speed matters because unresolved violations compound across multiple tax years.

Any residential rental property in California can trigger a substandard housing notice if a local government agency files a notice of noncompliance. Under Health & Safety Code Section 17920.10, cities and counties must report noncompliant properties to the FTB. This applies to single-family rentals, duplexes, apartments, and mixed-use properties with residential units.

Properties in cities with aggressive code enforcement programs get flagged most often. Los Angeles, San Francisco, Oakland, San Jose, and Sacramento run proactive inspection programs where inspectors examine rental properties on a regular schedule. Tenant complaints also trigger inspections. Even a single complaint about a broken heater or pest infestation can start the process that eventually reaches the FTB.

At The Reed Corporation, we work with landlords across California and see these notices concentrated in older housing stock. Pre-1970s buildings with deferred maintenance are the most common targets. We recommend our landlord clients get voluntary inspections done annually so violations are caught and fixed before any government agency gets involved.
