The ADA Grandfathering Myth: Why Your Pre-1990 Property Isn't Exempt

According to the ADA, Is There a Grandfather Clause?
If you own or operate a building that was constructed before the Americans with Disabilities Act (ADA) was passed in 1990, you might think you're "grandfathered" from accessibility requirements.
This is one of the most dangerous and costly misconceptions in property management and business operations.
The Bottom Line: There Is NO Grandfather Clause
The ADA contains no grandfathering provisions for buildings constructed before 1990. This means that regardless of when your property was built—whether it was constructed in 1776 or 1989—if it serves the public, you must comply with current accessibility standards.
Understanding Title III Requirements for Existing Buildings
Title III of the ADA specifically addresses public accommodations, which include restaurants, retail stores, hotels, theaters, medical offices, schools, and countless other businesses that serve the public. The law explicitly states that discrimination includes "failure to remove architectural barriers... in existing facilities" unless removing those barriers is not "readily achievable."
What "Readily Achievable" Means
The ADA defines readily achievable as modifications that are "easily accomplishable and able to be carried out without much difficulty or expense." This standard is intentionally flexible and considers factors such as:
The nature and cost of the required barrier removal
The overall financial resources of the facility
The number of people employed at the site
The effect on expenses and resources
Common Examples of Readily Achievable Improvements
According to the Department of Justice, readily achievable barrier removal often includes:
Installing ramps
Making curb cuts in sidewalks and entrances
Repositioning shelves, tables, or vending machines
Creating designated accessible parking spaces
Lowering telephones
Adding accessible door hardware
The "Safe Harbor" Exception: Limited Protection for Some Elements
While there's no grandfathering, the ADA does provide limited protection called "safe harbor" for certain building elements. This provision applies only to elements that were in compliance with the 1991 ADA Standards and have not been altered since March 15, 2012.
Important limitations of safe harbor:
It applies on an element-by-element basis
It doesn't apply to recreational facilities like swimming pools, play areas, or exercise equipment that weren't covered in the 1991 standards
If you choose to alter any element covered by safe harbor, it must then comply with current 2010 ADA Standards
Your Ongoing Legal Obligations
Immediate Requirements
Even if your building predates the ADA, you have immediate obligations to:
Remove readily achievable barriers - This is an ongoing obligation, not a one-time requirement
Provide program accessibility - Modify policies and procedures to ensure equal access
Allow service animals - Even with "no pets" policies
Provide reasonable accommodations - Such as sign language interpreters when necessary
Alteration Triggers Additional Requirements
If you make any alterations to your pre-1990 building (defined as almost any construction, repairs, or renovation affecting usability), you must:
Bring the altered area into full compliance with current standards
Improve the "path of travel" to the altered area
Upgrade restrooms, signs, and drinking fountains serving the altered area
The Financial Reality: Compliance vs. Lawsuit Costs
Waiting to be sued is an expensive strategy. If your business faces an ADA lawsuit, you could be responsible for:
Your own legal fees and costs
The plaintiff's legal fees and costs
Statutory damages (up to $4,000 per violation in California)
The cost of required improvements
Potential additional damages if someone is injured
Many insurance policies don't cover ADA violations, leaving you financially exposed.
California Provides Some Relief for Proactive Businesses
California's Construction-Related Accessibility Standards Compliance Act (CRASCA) offers reduced damages for businesses that take proactive steps:
$1,000 instead of $4,000 in damages if you hire a Certified Access Specialist (CASp) and correct violations within 60 days
$2,000 instead of $4,000 for small businesses that correct violations within 30 days without a CASp
Grace periods for small businesses following CASp inspections
What You Should Do Right Now
1. Accept Your Legal Responsibility
Treat ADA compliance like any other legal requirement—such as fire safety or health codes.
2. Get a Professional Assessment
Hire a Certified Access Specialist (CASp) to evaluate your property and identify violations. This investment can significantly reduce your legal exposure.
3. Create an Improvement Plan
Start with simple, low-cost improvements that address the most common barriers. Many accessibility improvements—like adding signs, restriping parking, or changing door hardware—are relatively inexpensive.
4. Prioritize Your Improvements
Focus on barriers in this order:
Entry access - Getting people through the door
Access to goods and services - Main business areas
Restroom access - If restrooms are provided to the public
Remaining barriers - Secondary improvements
The Bigger Picture: It's Good Business
Rather than viewing accessibility as a burden, consider the business opportunity. Making your business accessible opens it to a significant market segment.
Conclusion
Your pre-1990 building is not grandfathered from ADA requirements. The law requires you to remove readily achievable barriers regardless of when your building was constructed. The question isn't whether you need to comply—it's how quickly you can get started and how much protection you can build through proactive compliance efforts.
Don't wait for a lawsuit to force your hand. Take control of your accessibility obligations now, protect your business from costly legal exposure, and open your doors to the millions of potential customers with disabilities who are currently unable to access your services.
