Supplemental Statutory and Contractual Disclosures
The Transfer Disclosure Statement and Natural Hazard Disclosure cover a lot of ground, but California law requires disclosure of several other specific items that don't fit neatly into either of those forms. The Supplemental Statutory and Contractual Disclosures form, or SSD, is where those additional statutory requirements live. It's not the most exciting document in a listing package, but skipping it leaves real disclosure gaps.
Why This Document Matters
California layers a lot of specific disclosure obligations on top of the general TDS and NHD requirements. Mello-Roos special tax districts, military ordnance location notifications, industrial use zone proximity, and window security bar release mechanisms are just a few examples of statutory items that need their own disclosure but don't belong on the main TDS form. The SSD is the CAR-standard vehicle for covering these bases in one place.
Missing an item on the SSD isn't just a paperwork gap. Several of these disclosures are independently mandated by specific sections of California law, meaning a missing disclosure here can expose a seller to liability even if every other disclosure form was completed perfectly. Disclosure coordination that treats the SSD as an afterthought is missing a real compliance risk.
How It Works
The SSD is completed by the seller, typically with guidance from the listing agent, at the same time as the rest of the disclosure package, TDS, NHD, and SPQ. Unlike the NHD, which is prepared by a third-party company cross-referencing hazard maps, the SSD relies on the seller's actual knowledge and the property's specific circumstances.
Some items on the SSD apply broadly and get checked as not applicable for most properties, Mello-Roos, for instance, only applies if the property is in a Community Facilities District. Others require the seller and agent to actually research or confirm specific facts, such as whether the property is within a defined distance of a former military base with unexploded ordnance risk. Once completed, the SSD gets delivered to the buyer alongside the rest of the disclosure package.
Key Sections Explained
Mello-Roos and Special Assessment Districts covers whether the property is subject to a Community Facilities District special tax, which adds an additional line item to the buyer's property tax bill beyond standard property taxes. This is often overlooked because it doesn't show up clearly without checking specifically.
Military Ordnance Location discloses if the property is within one mile of a former federal or state military ordnance location, where unexploded munitions could potentially still be present. This applies to specific mapped areas and needs to be checked against those maps rather than assumed.
Industrial Use Zone Disclosure covers whether the property is affected by a zoning designation allowing industrial uses nearby that could affect the use and enjoyment of the property, such as noise, odor, or increased traffic.
Window Security Bars requires disclosure of any window security bars and confirmation that they have functioning quick-release mechanisms, which is a specific safety requirement under California law due to fire escape concerns.
Other Statutory Items can include additional disclosures depending on the property's specific location and history, since this form is designed to capture requirements that don't have a dedicated form of their own.
Common Mistakes to Avoid
Treating the SSD as a rubber-stamp form where everything gets marked "not applicable" without actually checking is a real risk. Mello-Roos status in particular is easy to get wrong if you're not verifying against the county's actual special assessment records.
Not checking window security bars for functioning release mechanisms is a life-safety issue disguised as a paperwork item. If a property has security bars, confirm they actually release properly before checking that box.
Skipping the SSD entirely because agents assume the TDS and NHD cover everything is a mistake that misses statutory requirements those forms simply don't address.
Not updating the SSD if new information comes to light during escrow, such as discovering a special assessment the seller didn't initially mention, leaves a stale disclosure in the file that doesn't reflect what's actually known.
Pro Tips from a TC
Check Mello-Roos status through the county assessor's office or a title company report rather than relying solely on the seller's memory. Sellers sometimes don't realize they're in a Community Facilities District, especially if they bought the home a long time ago.
If the property has window security bars, physically test the release mechanism during your listing walkthrough rather than taking the seller's word that it works.
Bundle the SSD into your standard disclosure package checklist so it never gets treated as optional. This is exactly the kind of item that disclosure coordination support catches before it becomes a gap.
If you're listing in an area near a former military base or industrial zone, do the extra research upfront rather than guessing. A quick call to the county planning department can confirm what actually applies.

Frequently Asked Questions
Q: Is the SSD required on every California listing?
It's standard practice to include it in every disclosure package, though many individual items on the form will be marked not applicable for a given property. The form exists to make sure the less common but still legally required disclosures aren't accidentally skipped, so it should be part of every listing's disclosure checklist regardless of the property's specific circumstances.
Q: What is Mello-Roos and why does it matter on this form?
Mello-Roos refers to a Community Facilities District special tax, an additional assessment some California properties carry on top of standard property taxes, often used to fund infrastructure like schools or roads in newer developments. Buyers need to know about this before closing since it directly affects their ongoing carrying costs, and it's disclosed specifically on the SSD.
Q: Who is responsible for verifying whether a property is near a military ordnance location?
The listing agent typically helps research this using publicly available maps of former military ordnance areas, though the disclosure obligation rests with the seller. If a property is in or near a mapped area, this needs to be disclosed regardless of whether the seller was previously aware of it.
