The City of Los Angeles SB 9 Tenant Declaration Form: What It Is, Why It Matters, and How to Fill It Out
If you're applying for a Two-Unit Development permit in the City of Los Angeles under SB 9 (2021), one of the documents LADBS requires as an attachment to your application is the Owner Declaration Related to Tenant Occupancy. It's a one-page form. Most people don't think twice about it — until they realize what they're actually signing.
Here's what the form is, what it's checking for, and what happens if you get it wrong.
What the Form Is
The Tenant Occupancy Declaration is issued by the City of Los Angeles Department of Building and Safety (LADBS) and is required as an attachment to any SB 9 Two-Unit Development building permit application. It's not optional. You can't submit your permit application without it.
The form has three sections:
Section I — Owner's Notice: A brief statement alerting the owner that tenant history on the property affects SB 9 eligibility
Section II — Owner's Project Information: A yes/no question asking whether any unit on the property has been tenant-occupied within the three years prior to the application submittal date
Section III — Owner's Declaration: A signature block where you declare, under penalty of perjury under California law, that your answer is true and correct
That last part matters more than it looks.
The Three-Year Tenant Protection Rule
SB 9 was designed to accelerate housing production — but not at the expense of existing tenants. One of the core tenant protections built into the law itself is that a property cannot be used for a Two-Unit Development if a tenant has occupied any residential unit on the site within the three years prior to the building permit application submittal date.
This is a hard stop. It doesn't matter if the tenant has since moved out. It doesn't matter if the lease expired naturally. If someone was renting a unit on that property at any point during that 36-month window, restrictions apply — and the City of Los Angeles will require you to disclose it.
The same lookback logic applies to demolition projects. Investors doing full-demo SB9 plays in LA County frequently run into this issue because the best candidate lots — the ones with the right square footage and lot size — tend to be existing rental properties. Rental history doesn't disappear when the tenant does.
What Happens If You Check "Yes"
If a tenant has occupied the property within the three-year window, you're required to disclose the address(es) and unit number(s) on the form. From there, Los Angeles City Planning will apply the relevant tenant protection restrictions to your project.
What those restrictions look like in practice depends on the specifics of your situation — rent control status, how recently the tenant occupied the unit, whether the property is covered by the Ellis Act, and other factors. The key point is this: checking "yes" doesn't automatically kill your project, but it does change what you can do and when.
What Happens If You Get It Wrong
This is where the form gets serious. Violations of the declaration — meaning you checked "No" when the answer should have been "Yes" — can result in:
Revocation of any permits already issued
Denial of the SB 9 application
Non-issuance of building permits and parcel maps
Additional legal penalties under California law
You're signing this under penalty of perjury. That phrase carries real weight. If you misrepresent tenant history on the form, even if it wasn't deliberate, LADBS has authority to pull everything that was issued as a result of that application.
How to Know If Your Property Is Affected
Before you file anything, run through this checklist:
Pull your rental history for the past 36 months. Check leases, rent receipts, bank deposits from tenants, and any written notices. If you self-managed, think carefully about who occupied the property and when.
Check every unit, not just the main house. The form asks about "one or more of the residential units on the property." A garage apartment, a basement unit, or a permitted ADU all count. If anyone was renting any of them in the past three years, that has to be disclosed.
Check Ellis Act history. Separately from the tenant three-year window, properties from which units were withdrawn from the rental market under the Ellis Act within the preceding 15 years are ineligible for SB 9 entirely.
Talk to the previous owner if you recently acquired the property. If you bought the property and aren't sure whether it was tenant-occupied before you closed, you need to find out. What you verify before closing on any LA County property should include a specific inquiry into tenant history — especially if SB 9 development is part of your plan.
Tenant History Affects More Than Just SB 9
The three-year lookback is specific to SB 9 Two-Unit Development applications, but the broader issue — tenant history shaping what you can do with a property — shows up in other contexts too.
If you own or are buying a property with tenants and you're thinking about any kind of development or repositioning, understanding how rental history constrains your options is foundational. Selling a tenant-occupied single-family rental in Orange County involves similar questions about what triggers what, and the same applies to buyers acquiring occupied properties with development intent.
On the acquisition side, buying a tenant-occupied property when your plan is to develop or reposition requires you to think through the SB 9 eligibility window before you're locked in. If the tenant vacates the day you close, you still have a three-year clock running before you can pursue a Two-Unit Development under SB 9. That affects your timeline and your pro forma, and it needs to be in your underwriting before you make an offer.
Where This Fits in the Broader SB 9 Process
The tenant declaration is just one piece of the LADBS application for a Two-Unit Development. LADBS processes Two-Unit Development permits directly — these go through Building and Safety, not Planning, though certain overlay zones may require a pre-filing meeting with City Planning staff before you submit.
If you're evaluating a property in LA for an SB 9 play — whether that's a two-unit development, a lot split, or the full four-unit stack investors are engineering in LA County — the tenant history question is one of the first filters, not the last. Find out the answer before you build a deal around a property, not after you've put it under contract.
The Bottom Line
The SB 9 Tenant Occupancy Declaration is a short form, but it's signed under penalty of perjury and directly controls whether your Two-Unit Development project can move forward. The three-year lookback applies to every residential unit on the property — not just the main house — and it starts from the date you submit your permit application, not the date the tenant left.
If you're not certain about the rental history on a property you own or are considering, find out before you file. Getting this wrong doesn't just delay a project — it can result in permits being pulled, approvals being revoked, and exposure to California legal penalties.
The form is available directly from LADBS. If you have questions after reviewing the notice, LADBS asks that you contact the Department of Building and Safety directly.
