Property Disclosures: A 2026 Seller’s Guide

Why Disclosures Matter in Santa Clarita, the SFV & Greater LA in 2026

Selling a home in Southern California means navigating one of the most seller-protective — and seller-obligated — disclosure frameworks in the nation. California law requires sellers to affirmatively tell buyers about known material facts affecting a property’s value or desirability, and the consequences of getting it wrong don’t end at closing. A buyer who discovers an undisclosed issue months or even years later can still bring a claim against you.

This is especially relevant across our region in 2026. Santa Clarita’s hillside communities sit within mapped High Fire Hazard Severity Zones. Many SFV neighborhoods have older housing stock with a longer history of permits, additions, and repairs to track. And Greater LA’s mix of seismic fault zones, flood-adjacent parcels, and aging infrastructure means the disclosure package you hand a buyer is rarely boilerplate — it needs to reflect your specific property and its specific history.

What California Law Requires You to Disclose

The Transfer Disclosure Statement (TDS)

The TDS is the core disclosure form for most residential resale transactions in California. It asks you to disclose known defects in the roof, foundation, plumbing, electrical, and other systems, along with any additions or alterations made without permits, neighborhood nuisances, and other material facts. The standard is “known to you” — you’re not expected to be a home inspector, but you are expected to be honest about what you’re aware of.

The Natural Hazard Disclosure (NHD) Report

This is where our region gets specific. An NHD report tells the buyer whether the property sits within a state-mapped hazard zone — and in Santa Clarita, the SFV, and much of Greater LA, at least one of these usually applies:

• Very High Fire Hazard Severity Zone — common in Santa Clarita’s hillside and canyon communities.
• Earthquake fault zone (Alquist-Priolo) — relevant to parcels near mapped active faults throughout the SFV and Greater LA.
• Flood zone — applicable to some lower-lying and river-adjacent parcels.
• Seismic hazard zone (landslide or liquefaction) — common in hillside and canyon terrain across the region.

These reports are typically ordered through a third-party provider and layered on top of your own personal knowledge disclosures — they don’t replace the TDS, they supplement it.

Local & Community-Specific Disclosures

If your home sits in a community with a Mello-Roos district, HOA, or other special assessment — common throughout many of Santa Clarita’s newer master-planned neighborhoods — you’ll need to disclose those obligations too, including current dues, special assessments, and any pending litigation the HOA is involved in. Lead-based paint disclosures apply to any home built before 1978, which covers a meaningful share of older SFV and Greater LA inventory.

It’s also worth noting that disclosure obligations don’t stop at the state forms. Local municipal requirements, well and septic disclosures for more rural SCV parcels, and even solar lease or PACE loan disclosures for homes with financed energy upgrades can all come into play depending on your specific property. This is exactly why a blanket, one-size-fits-all disclosure approach falls short across a region as varied as ours — a condo in the SFV, a hillside estate in Santa Clarita, and a mid-century home in Greater LA can each carry a very different disclosure footprint.

Common Disclosure Mistakes Sellers Make

• Assuming “it’s fixed, so I don’t need to mention it.” Past issues — even fully repaired ones — often still need to be disclosed if material.
• Leaving out unpermitted work. That finished garage or added bathroom needs to be disclosed even if it looks great.
• Forgetting neighborhood-level facts. Nearby construction, noise sources, or zoning changes can qualify as material.
• Relying on memory instead of records. Pulling old permits, invoices, and inspection reports before listing prevents gaps.
• Treating disclosure as a one-time task. If something changes or is discovered between listing and closing, an amended disclosure is required.

The safest approach is to start the disclosure process before your home ever goes live — not after an offer arrives. Walking through your property’s history with your agent, pulling permit records from the county or city, and gathering past inspection or repair paperwork gives you a complete, accurate picture to work from instead of trying to recall details under the time pressure of an active escrow.

Frequently Asked Questions

Do I have to disclose a past repair even if it’s already fixed? In most cases, yes — California’s standard is based on material facts known to you, not just current condition, so a properly repaired past issue (like a roof leak or foundation crack) generally still needs to be disclosed along with the repair that was made.

What happens if I forget to disclose something and the buyer finds out later? A buyer who discovers a known, undisclosed material defect after closing can pursue legal remedies against the seller, sometimes years later, which is exactly why thorough upfront disclosure is worth the extra time before you list.

Do disclosure requirements differ between Santa Clarita, the San Fernando Valley, and the rest of Greater LA? The underlying California disclosure laws are statewide, but which natural hazard zones, HOA/Mello-Roos structures, and local ordinances apply to your specific disclosure package depends heavily on your property’s exact location, which is why a locally experienced agent matters.
