If you own commercial property in California, your biggest accessibility exposure usually does not come from the federal government. It comes from private plaintiffs. ADA compliance for commercial landlords in California runs through two laws at once: the federal Americans with Disabilities Act and California’s Unruh Civil Rights Act, which turns a single architectural barrier into a damages claim. Owners who treat accessibility as a one-time construction item, instead of an ongoing legal duty, are the ones who end up defending lawsuits they could have avoided.
This guide covers where a commercial landlord’s liability actually sits, why the Unruh Act drives California’s lawsuit volume, and what a Certified Access Specialist inspection does to cap your damages.
Key Takeaway: A California commercial landlord’s core exposure runs through the Unruh Civil Rights Act (Civ. Code section 51), which attaches a minimum of $4,000 in statutory damages plus attorney’s fees to each ADA barrier a disabled patron encounters. You limit that exposure by obtaining a Certified Access Specialist (CASp) inspection under Civil Code section 55.53, removing readily achievable barriers, and allocating accessibility duties clearly in every lease.
Who is responsible for ADA compliance, the landlord or the tenant?
Both can be liable, and a plaintiff will usually name both. The Americans with Disabilities Act treats the property owner and the operating business as jointly responsible for an accessible place of public accommodation, so suing only one defendant is the exception, not the rule.
When the lease says nothing, the landlord keeps the exposure for the building shell and the common areas: parking, exterior paths of travel, entrances, and shared restrooms. The tenant usually controls the interior of its own space and the barriers created by its specific build-out and fixtures.
That default only holds while the lease is silent. In our experience defending property owners, the lease is where most of this gets decided, and a well-drafted one pushes a large share of the build-out compliance risk onto the operating tenant. We cover the drafting mechanics in our discussion of commercial lease disputes.
Why do California commercial landlords get sued so often for accessibility?
California sees a lopsided share of accessibility litigation because of state law, not federal law. The federal ADA gives a private plaintiff only injunctive relief and attorney’s fees. No money damages award is available under federal law alone.
The Unruh Civil Rights Act is what adds the money. By treating any ADA violation as a state civil rights violation and attaching statutory damages, it turns barrier removal into a paid claim, and that financial incentive is what drives the filing volume.
California accounts for most of the nation’s construction-related accessibility lawsuits despite having a fraction of the country’s businesses, and a small group of high-frequency plaintiffs files many of these cases. Reports to the Legislature have found that a handful of plaintiffs and a few law firms account for the bulk of these filings statewide. For owners trying to track overlapping obligations, our overview of compliance with local, state, and federal laws sets out the broader framework.
What does California law actually require of a commercial property owner?
California stacks state accessibility and disclosure duties on top of the federal baseline. A commercial landlord needs to understand four authorities, because plaintiffs and their counsel use all four.
The federal floor is ADA Title III (42 U.S.C. section 12181 and following), which requires places of public accommodation to remove architectural barriers where doing so is readily achievable, meaning achievable without much difficulty or expense. Alterations raise the bar, adding a duty to make the altered area and its path of travel accessible.
The Unruh Civil Rights Act (Civ. Code section 51) supplies the damages. It folds in ADA violations and adds a statutory minimum of $4,000 per offense plus attorney’s fees, which is the provision that makes California filings worth a plaintiff’s time.
The Construction-Related Accessibility Standards Compliance Act and its CASp program give you your defensive tools. A CASp inspection under Civil Code section 55.53 can reduce minimum statutory damages and, under Code of Civil Procedure sections 425.50 through 425.55, give a qualifying defendant a litigation stay and an early evaluation conference. Civil Code section 1938 separately requires you to state in every commercial lease whether the premises has been CASp-inspected. The full text of these provisions is available through the California Legislative Information portal.
ADA Title III versus the Unruh Act: what is at stake
The practical difference between the federal and state claims is money. Here is why almost every California accessibility complaint is pleaded under the Unruh Act rather than the ADA alone.
| Feature | ADA Title III (federal) | Unruh Civil Rights Act (California) |
|---|---|---|
| Money damages | None; injunctive relief only | Minimum $4,000 per offense |
| Attorney’s fees | Available to prevailing plaintiff | Available to prevailing plaintiff |
| Basis of liability | Failure to remove readily achievable barriers | Incorporates the ADA violation as a state claim |
| Effect of a CASp inspection | No statutory damages reduction | Reduced minimum damages and possible litigation stay |
| Who typically files | Individual plaintiffs | High-frequency litigants and individuals |
What are the most commonly cited ADA barriers in California lawsuits?
Most accessibility complaints cluster around the same short list of physical conditions, and almost all of them sit in the parts of the property a landlord controls. Knowing which barriers draw the filings lets an owner fix the highest-risk items first instead of guessing.
Parking is the single most litigated area. Complaints routinely allege too few accessible spaces, a missing van-accessible stall, faded or absent striping, signage mounted at the wrong height, and access aisles that are too narrow or sloped past the allowed tolerance. Because parking sits in the common area, the landlord almost always owns this exposure.
The accessible route is the next cluster. Plaintiffs cite too much running slope and cross-slope on walkways, abrupt level changes and thresholds at entrances, door hardware that requires tight grasping or twisting, and path-of-travel obstructions such as planters, merchandise, or outdoor seating that narrow the route below the required clear width.
Inside the building, restroom and counter conditions drive a large share of claims. Common allegations involve too little clear floor space and turning radius in restrooms, grab bars set at the wrong height or location, lavatory and pipe clearances, and sales or service counters built above the maximum accessible height. A CASp report flags each of these against the applicable standard, which is why owners who hold a current report can triage repairs by exposure rather than by guesswork.
How should a commercial owner respond to an ADA or Unruh demand letter?
Do not ignore the letter, and do not call the plaintiff’s counsel to argue the merits on your own. A demand letter is the opening move in litigation that carries statutory damages and a fee award, and your early decisions shape the entire case. The goal in the first two weeks is to protect your options, not to react.
Start by preserving evidence. Keep the demand letter, photograph the conditions it identifies, and pull your CASp report, remediation records, and the lease for the tenant whose space is involved. Then retain counsel experienced in defending Unruh and ADA claims rather than treating the demand like a routine slip-and-fall notice, because the procedural tools here are specific to accessibility law.
Next, look at your CASp status. If the property holds qualifying CASp-inspected status, a defendant may be entitled to a court-ordered stay and an early evaluation conference under Code of Civil Procedure sections 425.50 through 425.55, plus a reduction in minimum statutory damages. Counsel should test each alleged barrier against the actual standard, because plaintiffs frequently overstate the violations or cite conditions that already comply.
Then separate the readily achievable fixes from the contested ones. Correcting the simple barriers promptly and documenting the work narrows the dispute and undercuts a claim for ongoing injunctive relief. From there you weigh an early settlement against a defense on the merits, a call that turns on how strong the alleged barriers are, what your records show, and how the lease allocates the cost. Where the tenant’s build-out created the barrier, your lease indemnity provisions become central, which ties back to how these duties get drafted in the first place.
How does a CASp inspection reduce a commercial landlord’s exposure?
A CASp inspection is the single most effective step a California commercial owner can take to limit accessibility damages. A Certified Access Specialist is a state-licensed professional who inspects your property against the applicable construction-related accessibility standards and issues a report.
If your property has been CASp-inspected and you are sued, qualifying for “CASp-inspected” status can cut the minimum statutory damages a plaintiff may recover, in some cases from $4,000 to as low as $1,000 per offense, and can trigger a court-ordered stay and early evaluation conference under Code of Civil Procedure sections 425.50 through 425.55. That stay buys you time to correct identified barriers before the case moves forward.
In our experience defending property owners, an inspection finished before a complaint is filed is worth far more than one started after, because the damages-reduction and stay provisions reward owners who acted in advance. The report doubles as a documented remediation roadmap, which strengthens your position in any later fight over what was readily achievable.
How should a commercial lease allocate ADA responsibility?
Your lease should assign every accessibility duty in writing rather than leaving it to the statutory default. Silence is what breeds the disputes, because each side then argues the barrier belongs to the other party.
A well-drafted commercial lease settles at least three points: who handles barriers in the common areas versus the leased premises, who pays for compliance work triggered by the tenant’s specific use or build-out, and which party defends and indemnifies an accessibility lawsuit. The mandatory Civil Code section 1938 CASp disclosure belongs in the same document.
The table below is a common allocation owners use as a starting point. Every deal is different, and the right structure depends on the asset and the tenant.
| Compliance area | Typical landlord responsibility | Typical tenant responsibility |
|---|---|---|
| Building shell and structure | Yes | No |
| Common areas, parking, exterior path of travel | Yes | No |
| Interior of leased premises | No | Yes |
| Barriers caused by tenant’s build-out or use | No | Yes |
| CASp disclosure in lease (Civ. Code 1938) | Yes | Acknowledges |
Owners negotiating these terms should review how we structure the agreement in our California commercial lease agreement guide, and bring counsel in before signing.
What should a California property owner do before a demand letter arrives?
The owners who fare best treat accessibility as preventive maintenance, not as a response to litigation. By the time a demand letter or complaint lands, most of your best defensive options have already narrowed.
A workable pre-litigation program is short. Commission a CASp inspection and keep the report current. Remove readily achievable barriers on a documented schedule and keep the records. Confirm your leases carry the Civil Code section 1938 disclosure and a clear allocation of duties. Owners running multiple tenants should fold this into the broader operational issues we cover in commercial landlord-tenant disputes.
When a complaint does arrive, your CASp status, your remediation records, and your lease terms become the spine of your defense. You build that record now, not after you are served. For owners setting a full risk posture across a portfolio, our commercial real estate practice page explains how we approach these matters.
Frequently asked questions
Are commercial buildings required to comply with the ADA in California?
Yes. All commercial buildings that function as places of public accommodation must comply with ADA Title III, which requires removal of architectural barriers where readily achievable. In California, the same conditions also expose the owner to Unruh Act damages, so compliance carries higher financial stakes than in most states.
How much can a plaintiff recover for an ADA violation in California?
Under the Unruh Civil Rights Act, a plaintiff can recover a statutory minimum of $4,000 per offense plus attorney’s fees, even without proving actual damages. The federal ADA by itself awards no money damages, which is why these claims are almost always filed under California law.
Does a CASp inspection prevent ADA lawsuits?
No. A CASp inspection does not make you immune from suit, but it can substantially reduce your exposure. Qualifying CASp-inspected status can lower the minimum statutory damages and entitle you to a litigation stay and early evaluation conference, giving you time to fix barriers before the case advances.
How quickly should I respond to an ADA demand letter?
Treat it as urgent. Preserve the letter and the conditions it identifies, gather your CASp report and lease, and get it to counsel within days rather than weeks. The early window is when the CASp stay, the early evaluation conference, and prompt remediation can still shape the outcome, and waiting forfeits those options.
Is the landlord or the tenant responsible for ADA compliance?
Both can be liable, and plaintiffs usually sue both. The landlord generally keeps responsibility for the common areas and the building shell, while the tenant generally handles its own interior build-out. The lease can shift these duties, which is why precise drafting matters.
What is the Civil Code section 1938 disclosure in a commercial lease?
Civil Code section 1938 requires a commercial landlord to state in the lease whether the property has been inspected by a Certified Access Specialist. If it has not, the lease must include specific statutory language putting the tenant on notice. It is a routine but mandatory part of California commercial leasing.
