An SNDA agreement is the document your landlord’s lender sends when it makes a loan secured by the building you lease. SNDA stands for subordination, non-disturbance and attornment agreement, and the tenant, the landlord and the landlord’s lender all sign it. It decides whether your lease survives a foreclosure by that lender, and who your landlord becomes.

What Is an SNDA Agreement?
An SNDA agreement is a three-party contract among a tenant, its landlord and the landlord’s lender. The tenant subordinates its lease to the lender’s loan. The lender promises not to disturb the tenant’s occupancy after a foreclosure if the tenant isn’t in default. The tenant agrees to attorn, meaning it accepts the new owner as landlord.
Our commercial real estate glossary defines it the same way. Its core protections come into play if a lender holding a mortgage or deed of trust on the property forecloses.
The three partsWhat Do Subordination, Non-Disturbance and Attornment Mean?
Each word is a separate promise. Two benefit the lender, and one benefits the tenant.
| Part | What it says | Mainly protects |
|---|---|---|
| Subordination | The tenant’s leasehold interest ranks below the lender’s mortgage, so the lender’s lien takes priority over the lease. | Lender |
| Non-disturbance clause | If the tenant isn’t in default, it stays, and the lease continues as if the foreclosure never happened. | Tenant |
| Attornment clause | The tenant accepts the lender, foreclosure buyer or other successor as its landlord. | Lender and successors |
Per Holland & Knight, June 2026
Non-disturbance is “the most critical element of the SNDA from a tenant’s perspective.” Attornment means “effectively consenting in advance to accept a successor landlord with whom it has no prior relationship.” Source: SNDAs from the Tenant’s Perspective.
The attornment clause can work on its own. The American College of Real Estate Lawyers (ACREL) model tenant form makes attornment “effective and self-operative without the execution of any further instruments” once the lender succeeds to the landlord’s interest.
The lender’s sideWhy Does Your Landlord’s Lender Want You to Sign an SNDA?
Because the lender wants to be first in line. When a lender makes a commercial real estate loan secured by leased property, it will typically require an SNDA. Per Nolo, most lenders won’t accept a commercial property as security unless their mortgage interest is superior to the tenants’ leasehold interests.
Poyner Spruill says a lender should typically still require an SNDA even when the commercial lease already has automatic subordination language, because the SNDA adds protections and rights. Whether you’re on a triple net lease or another of the types of commercial leases, the SNDA is a separate agreement. Your own bank may want one too, as a closing condition on a business loan (McLane Middleton). Lenders sometimes skip small tenants that haven’t recorded a memo of lease.
Expect the first draft to favor the lender. Hawley Troxell calls the standard SNDA a “pro-lender” form.
ForeclosureWhat Happens to Your Lease in a Foreclosure Without an SNDA?
It depends on state law and on which came first, the lease or the loan. McLane Middleton says the tenant’s right to stay depends primarily on the state’s recording acts and foreclosure law, and commercial tenants have fewer safeguards than residential ones.
Jaburg Wilk explains the general mechanics. A lease that exists when the lender records its security interest is superior to it. Signing an SNDA means agreeing “to reverse the priorities,” and absent non-disturbance, the lender or foreclosure buyer “would have the right to terminate the lease upon completion of the foreclosure.” You give up priority; non-disturbance is what you get back.
California context · statutes and legal references
- Power of sale. Per Cornell’s Legal Information Institute, deeds of trust almost always allow a non-judicial foreclosure, with no court order first.
- Recording. Under Civil Code §1214, an unrecorded conveyance, “other than a lease for a term not exceeding one year,” is void against a later good-faith purchaser or mortgagee for value who records first; §1215 counts any written instrument creating an interest as a conveyance. Ask your attorney whether to record a memorandum of lease.
- Quiet enjoyment isn’t non-disturbance. That implied covenant is your landlord’s promise, not the lender’s.
Does an SNDA Protect You When the Property Sells?
Mostly indirectly. An SNDA’s core protections are triggered by foreclosure, and in an ordinary California sale the Civil Code already handles the handoff.
Civil Code §821 gives the buyer of leased property “the same remedies for recovery of rent” and lease performance that the seller had. §1111 makes the transfer effective “without attornments of the tenants,” and a tenant who paid rent to the seller before notice of the sale must not “suffer any damage thereby.”
An SNDA can still reach a sale. Per Nolo, the attornment clause obligates tenants to accept a new owner after a typical sale or a foreclosure, and ACREL’s model form extends attornment to “the grantee of the Premises from Landlord.” Planning a sale-leaseback? You’ll be signing a new lease, and lenders on leased property typically require SNDAs, so negotiate its SNDA terms up front.
The negotiationWhat Should Tenants Negotiate in an SNDA Commercial Lease?
Negotiate the SNDA in the lease itself, before you sign. Holland & Knight says that’s the most effective time, “not after a lender presents its own form.” Put the landlord’s duty to obtain SNDAs from current and future lenders in the letter of intent or the SNDA lease clause, early in negotiating a commercial lease.
| Issue | Typical lender form | Tenant’s ask |
|---|---|---|
| Unfunded TI, landlord work, free rent | Lender not obligated to finish landlord work or pay owed allowance | Protect them; they’re among a tenant’s biggest foreclosure risks |
| Landlord default | Lender may cure before the tenant can terminate | A defined, limited cure period |
| Casualty | Insurance proceeds pay down the loan | Proceeds go to rebuilding |
| Lease amendments | Lender approval required first | A narrower consent right |
| Future lenders | Automatic attornment | No automatic attornment to unknown future lenders |
| Prepaid rent, deposits | Carve-outs for rent paid “for more than the current month” and “any security deposit” | Know which payments a successor may not honor |
| Recording | Varies by form | If a notice of lease was recorded, record the SNDA so it binds successors |
How much moves depends on leverage. Per Nolo, whether a landlord includes a non-disturbance clause “depends on the tenants’ negotiating power.” Tenant representation settles these business terms early; your attorney handles the drafting.
ExceptionsWhen Might a Tenant Skip an SNDA or Get Only Subordination?
When the protection isn’t worth the time and money, or the tenant is related to the landlord. BFV Law’s factors: whether rent is above or below market, whether the land is a redevelopment opportunity, and the likely foreclosure buyer.
For a related-party lease, Poyner Spruill says the lender should consider subordination only, with no non-disturbance. That matters to owner-users holding real estate in one entity and the business in another, a structure to plan for when buying the building you occupy.
For owners, lenders typically require SNDAs when they lend on leased property, so it pays to spell out the SNDA process in the lease before a refinance. That’s a lease term worth settling through landlord representation.
Two lender documentsSNDA vs. Estoppel Certificate: What’s the Difference?
An SNDA sets future rights and priority; an estoppel confirms today’s lease facts. Lenders typically require both. Buyers can track both on our due diligence checklist.
| Question | SNDA | Estoppel certificate |
|---|---|---|
| What it does | Sets priority and the tenant’s rights in a foreclosure | Tenant confirms rent, term, deposits and any landlord defaults |
| Who signs | Tenant, landlord and lender | Tenant, for a buyer or lender |
| Underwriting weight | Secures lender priority | Often more important, per Hawley Troxell |
Key Takeaways
- An SNDA agreement has three parts: subordination and attornment benefit the lender; non-disturbance benefits the tenant.
- Its protections matter in a foreclosure; in a California sale, Civil Code §821 and §1111 handle the handoff.
- Negotiate it in the lease or letter of intent, not after the lender’s form arrives.
- Protect unfunded TI, landlord work, free rent, cure rights and casualty proceeds.
- Apex is not a law firm. Have your attorney review any SNDA before you sign.
SNDA Agreements: Frequently Asked Questions
What does SNDA stand for in a commercial lease?
SNDA stands for subordination, non-disturbance and attornment. An SNDA agreement is signed by the tenant, the landlord and the landlord’s lender. Subordination and attornment benefit the lender; non-disturbance benefits the tenant.
Do I have to sign an SNDA?
It depends on your lease, which may already require one or contain automatic subordination language. Lenders typically require SNDAs when they lend on leased property. Have your attorney review your lease and any form before you sign.
What happens to my lease in a foreclosure if I don’t have an SNDA?
It depends on state recording and foreclosure law and on whether your lease or the loan came first. Jaburg Wilk notes that, absent non-disturbance, a senior lender or foreclosure buyer would have the right to terminate the lease.
Does an SNDA protect my lease if the building is sold?
SNDA protections center on foreclosure. In an ordinary California sale, Civil Code section 821 gives the buyer the seller’s lease remedies, and section 1111 protects rent paid before notice of the sale. SNDA attornment clauses can also cover a new owner.
What’s the difference between an SNDA and an estoppel certificate?
An SNDA sets priority and the tenant’s rights if the lender forecloses. An estoppel is the tenant’s signed confirmation of lease facts. Lenders typically require both, and Hawley Troxell notes the estoppel is often more important to underwriting.
Should an SNDA be recorded?
Holland & Knight advises that where a notice of lease has been recorded, the SNDA should be recorded too, so it binds successors. California Civil Code section 1214 shows why recording order can matter. Ask your attorney.
Can a tenant negotiate the lender’s SNDA form?
Yes. Lender forms start pro-lender, and how much changes depends on your negotiating power. The best time is during lease negotiation, before the lender’s form arrives.
Leasing space in a financed building?
Get the business terms right before the lender’s form shows up. Robert Mendieta Jr., CCIM, will review the business terms of the lease and the SNDA agreement it calls for.
