Understanding ADA Rules in California: A Complete Guide for Developers
In California, accessibility rules are more than a set of building codes. They are part of a statewide effort to ensure that all people can use spaces without barriers. For developers, investors, and property owners, these rules are both a legal requirement and a way to add lasting value to a project.
The Americans with Disabilities Act (ADA) sets national standards. California adds another layer through its own building codes. Together, they shape how you design, build, and maintain your property.
At JDJ Consulting Group, we help clients bring these rules into their projects from day one. This prevents delays, avoids expensive changes, and ensures spaces are both compliant and welcoming.
In this guide, we explain:
How federal and California rules work together
Why Title 24 often goes beyond the ADA
How early planning avoids lawsuits and costly retrofits
Federal ADA Standards vs. California’s Title 24 Accessibility Requirements
California developers must follow both federal and state rules. The federal ADA applies across the U.S. California’s Title 24 adds its own building requirements, many of which are stricter.
Here’s the difference:
The ADA is a civil rights law. It ensures equal access to public spaces and services.
Title 24 is part of the California Building Standards Code. It sets technical construction details for accessibility.
These rules overlap. However, passing an ADA review does not mean you meet Title 24. In many cases, Title 24 requires more—such as wider parking spaces, stricter ramp slopes, and specific restroom layouts.
Comparison: ADA vs. Title 24
| Category | Federal ADA (2010 Standards) | California Title 24 |
|---|---|---|
| Authority | U.S. Dept. of Justice | CA Building Standards Commission |
| Legal Type | Civil rights law | Building code |
| Updates | Rare | Every 3 years |
| Enforcement | Federal lawsuits, DOJ actions | Local building inspections |
| Common Differences | National minimums | Often stricter, more detailed |
| Scope | Public spaces and businesses | All building projects in CA |
Takeaway: To build in California, you must meet both sets of rules at the same time.
The 2010 ADA Standards for Accessible Design
The 2010 ADA Standards define how public and commercial spaces should be built or remodeled. They cover:
Doorway widths and hallway space
Parking spot sizes and locations
Restroom features like grab bars and sinks
Ramp slopes and landings
Signage with tactile lettering
For JDJ clients, these rules are not just paperwork. They guide decisions that can save time and money. Addressing accessibility during design prevents expensive fixes later.
Our process helps you:
Plan ahead so your design meets both ADA and Title 24 rules.
Avoid costly changes once construction starts.
Reduce legal risk from lawsuits or complaints.
When you meet these standards from the start, your project runs smoother, and your property serves everyone better.
Title 24 in California: Building Code Requirements and Stricter Accessibility Rules
Title 24 is California’s own set of building standards. It covers every aspect of construction, from structural safety to energy use, and it also includes accessibility requirements. These rules often go beyond what the federal ADA demands.
For example, Title 24 might require:
Wider accessible parking spaces
Stricter ramp slope limits
More detailed restroom layouts
Specific door hardware for easier use
Because it is part of the California Building Standards Code, Title 24 is updated every three years. The ADA updates less often. This means a design that met the rules a few years ago might not pass today’s inspection.
At JDJ Consulting Group, we track these updates for our clients. By reviewing plans before permits are submitted, we help avoid changes that delay projects or increase costs.
Common Developer Mistakes Under Title 24 (and How to Avoid Them)
Even experienced developers can miss details in Title 24. A missing sign, a slightly steep ramp, or a narrow parking aisle can all trigger compliance issues. Below is a quick look at frequent errors and how to prevent them.
| Common Mistake | Why It’s a Problem | Compliant Solution |
|---|---|---|
| Accessible parking space is the ADA minimum but too narrow for Title 24 | California requires wider spaces and specific striping | Design parking to Title 24 width and add required markings |
| Ramp slope meets ADA but exceeds Title 24 limit | CA limits slopes more strictly | Adjust ramp design to meet both standards |
| Restroom layout ignores turning radius rules in Title 24 | Wheelchair users need more clear floor space | Increase layout dimensions before permitting |
| Door hardware meets ADA but not Title 24 reach range | CA requires handles and locks within a set height range | Install hardware within Title 24 reach limits |
| Signage meets ADA visual rules but lacks tactile lettering | Title 24 adds tactile and braille requirements | Include tactile and braille signage on all required doors |
Tip: When in doubt, design to the stricter rule. That way, you’ll meet both ADA and Title 24 without having to make changes later.
State-Level Protections: Unruh Act and Disability Access Laws
In California, accessibility laws do not stop with the ADA and Title 24. The Unruh Civil Rights Act adds another layer of protection. It applies to all business establishments in the state, including rental properties, hotels, offices, and retail spaces.
The Unruh Act says businesses cannot discriminate based on disability, and it directly incorporates ADA requirements. That means if you violate the ADA, you are also violating the Unruh Act.
One major difference is the penalties. Under the Unruh Act, each violation can cost a minimum of $4,000, plus attorney’s fees. If a property has several violations—like multiple restrooms or entrances out of compliance—costs can add up quickly.
SB 269 and SB 585: Small Business Protections
Lawmakers have tried to give small businesses more breathing room to fix problems.
SB 269 (2016) allows some businesses a short time to correct specific minor violations before facing full penalties.
SB 585 is a newer bill that could expand this protection. It proposes a 120-day “cure period” after being notified of a violation. If the business fixes the issue in time, they can avoid a lawsuit.
SB 585 is not yet permanent law, but developers and property owners should watch it closely. JDJ Consulting tracks these changes so clients can respond quickly when the rules shift.
Why These Laws Matter for Developers
For developers and owners, state-level protections can be both a risk and an opportunity. On one hand, California laws allow more lawsuits than federal law. On the other, knowing the rules early can help you design a property that avoids legal trouble altogether.
At JDJ Consulting Group, we:
Review plans for ADA and Title 24 compliance before submission
Conduct walk-through inspections during construction
Work with Certified Access Specialists (CASp) to identify and correct risks
Advise clients on legal changes like SB 585 so they can act before problems arise
Explore Topics — ADA & California Accessibility
Risk Mitigation: CASp Inspections and Legal Protections
Even with careful planning, accessibility issues can be missed. That’s where a Certified Access Specialist (CASp) becomes valuable. A CASp is trained and licensed by the state to inspect buildings for compliance with both the ADA and California’s Title 24.
Hiring a CASp before opening your property has two big benefits. First, it allows you to find and fix issues early. Second, it can give you legal advantages if a lawsuit is filed. California law recognizes property owners with CASp inspections as “qualified defendants.” This status can reduce penalties and even pause legal proceedings while corrections are made.
How CASp Inspections Work
A CASp review usually includes:
Plan Review – Checking architectural drawings before construction begins.
On-Site Inspection – Measuring spaces, slopes, and clearances to confirm they meet code.
Compliance Report – Listing any violations, with guidance on how to fix them.
Follow-Up Visit – Confirming corrections have been made before final sign-off.
Why Developers Should Integrate CASp into Every Project
Many developers wait until the city inspection to think about accessibility. By then, fixing a noncompliant ramp or restroom could mean costly demolition. At JDJ Consulting Group, we schedule CASp inspections at key project stages so problems are addressed while changes are still easy to make. Call us at (818) 233-0750 to schedule your free consultation today!
Benefits for JDJ clients:
Reduced legal exposure under ADA and the Unruh Act
Faster permitting and smoother final inspections
A documented compliance history, useful if disputes arise
Stronger trust with tenants, buyers, and the public
Accessibility Requirements in Specific Built Environment Areas
Accessibility rules apply to every part of a building or site that people use. Some areas draw more attention from inspectors and are more likely to trigger violations. Parking, restrooms, and public walkways are among the most common problem spots.
Knowing these details during design can save a project from costly changes after construction. At JDJ Consulting Group, we make sure these elements are built to meet both ADA and California Title 24 requirements from the start.
Accessible Parking: ADA and Title 24 Standards
Parking rules are stricter in California than in most other states. While the ADA sets a national minimum, Title 24 often calls for more accessible spaces and larger dimensions.
Basic parking requirements:
At least one accessible space for every 25 total spaces
One in every six accessible spaces must be van-accessible
Spaces must have access aisles, marked with clear striping
Signs must be posted at a set height with the international symbol of accessibility
Title 24 also specifies the exact slope of parking surfaces and the size of access aisles. Even a small slope beyond the limit can cause a failed inspection.
Restrooms and Public Facilities
Restrooms are another common source of violations. Both the ADA and Title 24 require:
Grab bars placed at specific heights
Sinks with clear space underneath for wheelchair access
Mirrors and dispensers mounted at reachable heights
Adequate turning space for wheelchairs
Title 24 can require slightly different measurements than the ADA. Designing to the stricter dimension ensures compliance under both laws.
Other Critical Features
Beyond parking and restrooms, inspectors also look at:
Paths of travel – Sidewalks, hallways, and ramps must meet width and slope rules
Doorways – Minimum widths and handle designs for easy operation
Signage – Visual and tactile signs at required locations, mounted at proper heights
By addressing these features during early planning, JDJ clients avoid delays and keep their projects on schedule.
Accessibility Readiness Checklist — ADA & Title 24
Quickly assess your property for common accessibility issues. This checklist covers physical and digital items like accessible parking, paths of travel, restrooms, and web content (WCAG).
Digital Accessibility: Websites and Online Platforms
Accessibility is not just about physical spaces. In California, the rules also extend to websites and digital tools. Many businesses don’t realize that the ADA and California laws can apply to their online presence.
If a customer cannot use your website due to design barriers, it can be treated like a physical access violation. This has led to a rise in lawsuits against companies that fail to make their sites usable for people with disabilities.
What Digital Compliance Means
Digital compliance follows the Web Content Accessibility Guidelines (WCAG). These rules cover how websites should be built so everyone can use them.
Key principles include:
Perceivable – Content can be read, heard, or seen in different formats
Operable – Users can navigate using a keyboard, mouse, or assistive device
Understandable – Clear language and predictable navigation
Robust – Works across different devices and assistive technologies
In California, failing to meet these standards can trigger both ADA and state-level penalties.
Common Online Accessibility Features
| Feature | Purpose | Example |
|---|---|---|
| Alt text | Describes images for screen readers | “Front view of JDJ Consulting Group office” |
| Keyboard navigation | Lets users move through the site without a mouse | Tab key to move between links |
| Color contrast | Improves visibility for low-vision users | Dark text on light background |
| Captioning | Makes videos accessible to deaf or hard-of-hearing users | Subtitles on promotional videos |
Adding these features is not only about legal safety — it also improves the user experience for everyone.
Why It Matters for JDJ Clients
For JDJ Consulting Group clients, digital accessibility is part of a full compliance strategy. A well-designed, accessible website can:
Reach a wider audience
Reduce the risk of lawsuits
Improve search engine rankings
Build a stronger public image
We advise integrating digital accessibility early, just like physical design compliance. This prevents rushed fixes and keeps your brand consistent across platforms.
Inspection, Enforcement, and Penalties in California
Compliance isn’t just a checklist. In California, inspections and enforcement are active processes. Both government agencies and private parties can bring violations to light.
You might face an inspection after:
A routine check by a city or county building department
A complaint from a customer or advocacy group
A review triggered by a building permit application
A lawsuit filed in state or federal court
Once a violation is found, timelines for correction are strict. Delays can raise fines and legal costs.
Who Enforces the Rules?
Different agencies play a role depending on the issue.
| Enforcement Body | Focus Area | How They Act |
|---|---|---|
| California Division of the State Architect (DSA) | State building accessibility standards | Reviews plans and inspects public facilities |
| Local Building Departments | City and county code enforcement | Conducts site inspections and approves permits |
| California Department of Fair Employment and Housing (DFEH) | Discrimination and public access | Investigates complaints and can impose penalties |
| Federal Department of Justice (DOJ) | ADA compliance | Brings lawsuits and settlements for federal violations |
Penalties for Non-Compliance
Ignoring accessibility rules can be costly. California law often combines state penalties with federal fines, creating steep totals.
ADA Civil Penalties: Up to $75,000 for the first violation, $150,000 for later ones
California Civil Penalties: Minimum $4,000 per violation under the Unruh Act
Legal Fees: Plaintiffs can recover attorney’s costs, which often exceed fines
Lost Business: Customers who face barriers often don’t return
JDJ’s Role in Prevention
For JDJ Consulting Group clients, prevention is more affordable than correction. We help:
Audit properties for both ADA and Title 24 compliance
Coordinate with Certified Access Specialists (CASp)
Integrate fixes into renovation or development timelines
Prepare documentation to show good-faith compliance efforts
With these steps, clients lower their legal exposure and maintain stronger community trust.
Final Thoughts – Making Compliance Work for You
ADA and California Title 24 compliance is not only a legal box to check. It’s part of building trust, avoiding lawsuits, and creating spaces everyone can use.
For many property owners, the challenge is not knowing where to start. The rules are detailed, and small mistakes can lead to big costs. The good news? With the right planning, compliance can fit into your timeline and budget.

FAQ 13 – What are the parking requirements for ADUs in California?
Parking rules for ADUs in California are more flexible than for regular housing. State law limits what cities can require, especially if your ADU is in a transit-friendly area. In Los Angeles and other urban zones, many ADUs qualify for zero parking requirements.
Key points:
No parking needed if the ADU is within 0.5 miles of public transit.
Garage conversions do not require replacement parking.
Cities can allow tandem or driveway spaces.
Rules must not make building an ADU impossible.
FAQ 14 – Can I rent out my ADU in California right away?
Yes, most homeowners can rent their ADU soon after getting final approval. California ADU laws allow long-term rentals, but short-term rentals like Airbnb may be restricted in certain cities, including parts of Los Angeles.
Important details:
Long-term rentals are 30+ days.
Many cities ban short-term ADU rentals.
Always confirm local rental ordinances first.
Some cities require a business license for rentals.
FAQ 15 – Do ADUs increase property taxes in California?
Building an ADU may raise your property taxes, but only for the added value. Under Proposition 13, the original home’s assessed value stays the same in most cases.
What to expect:
Taxes apply only to the new ADU’s value.
The assessor calculates ADU value separately.
Average tax rate is around 1% in most counties.
Large upgrades to the main home can affect taxes.
FAQ 16 – What size ADU can I build in California?
California ADU laws set maximum sizes, but local zoning can adjust these limits. In Los Angeles, most detached ADUs can be up to 1,200 square feet, but smaller lots may face additional restrictions.
