ADA Compliance Requirements For Commercial Buildings Built Before 1993 In DC

Key Takeaways: If your commercial building in DC was built before 1993, it’s almost certainly not fully ADA compliant. The 1991 ADA Standards don’t apply retroactively, but any renovation, alteration, or change in use triggers compliance for that specific area. The real-world standard is “readily achievable barrier removal,” a fluid concept that depends entirely on your building’s specific layout and finances. Ignoring it is a major liability.

We get this call all the time. A business owner in a beautiful, historic row house in Adams Morgan or a sturdy old warehouse-turned-office in Ivy City is finally ready to update their space. Maybe they’re refreshing the lobby, redoing the bathrooms, or just changing tenants. Then their architect or contractor mentions “ADA triggers,” and the panic sets in. The assumption is that because the building has been standing since the Reagan era, it’s grandfathered in. That’s the most common—and most expensive—misunderstanding we see.

The Americans with Disabilities Act (ADA) isn’t a building code you pass once. It’s a civil rights law. For buildings constructed before the ADA took effect in 1993, the obligation isn’t to magically become 100% compliant overnight. Instead, the law imposes a continuous, ongoing duty to remove architectural barriers where it is “readily achievable” to do so. And any time you alter a “primary function area,” you trigger a path of travel obligation that can extend far beyond the construction zone.

What does “readily achievable” actually mean for an older DC building?
It’s the million-dollar question, literally. The term is deliberately flexible, defined as “easily accomplishable and able to be carried out without much difficulty or expense.” We’ve sat across tables from building owners and seen the frustration—it feels vague because it is. But in practice, we interpret it through a hierarchy of actions. It’s not an all-or-nothing mandate, but a series of prioritized steps. The first things we look at are always entry and access. If someone can’t get in, nothing else matters.

Featured Snippet: Barrier Removal Priority
For pre-1993 buildings, ADA compliance focuses on “readily achievable barrier removal.” This is a flexible standard based on your resources. Priority is typically given to: 1) Providing an accessible entrance, 2) Making goods/services available (e.g., lowering a service counter), 3) Restroom modifications, and 4) Creating accessible parking. The goal is incremental progress toward access.

From our experience in older DC neighborhoods like Georgetown and Capitol Hill, the most common “readily achievable” fixes we start with are:

• Installing a simple, surface-applied ramp at a single step entry.
• Replacing a heavy entrance door with excessive opening force.
• Re-striping a parking lot to create a van-accessible space.
• Adding tactile signage and ensuring door hardware is operable with a closed fist.
  These are relatively low-cost, high-impact changes. The trouble starts when the building’s structure makes simple solutions impossible. That’s when you need a professional assessment to document the challenges and define the scope of what is—and isn’t—readily achievable for your specific property.

The Renovation Trigger: When “Grandfathered” Goes Out the Window

This is where we see well-intentioned projects derail. Let’s say you own a pre-1993 building in Silver Spring, MD, just over the DC line, and you decide to renovate your second-floor office suite. You think you’re only responsible for that suite. Not quite.

The ADA requires that when you alter a “primary function area” (like offices, a retail sales floor, or a cafeteria), you must also make the “path of travel” to that area accessible. This includes restrooms, telephones, and drinking fountains serving the area. Crucially, the 20% Rule applies: if the cost of the path of travel improvements exceeds 20% of the total alteration cost, you are only required to spend up to that 20% threshold. You need a clear, documented cost analysis to navigate this.

We worked with a client in a 1920s building near U Street who was redoing their kitchen. The path of travel analysis meant we had to look at the entrance, the hallway, and the restroom. The restroom upgrade alone hit the 20% cap, which we documented thoroughly. This allowed them to proceed with the kitchen project legally, with a clear record of compliance efforts.

Common Pitfalls in Older DC Architecture

The charm of DC’s older commercial stock is also its biggest ADA headache. Here’s what we consistently run into:

• Historic Designation Complications: Being on the Historic Register doesn’t exempt you. It means you must pursue compliance through the minimum feasible standard, which requires coordination with the State Historic Preservation Office. It’s a process, not a pass.
• The Single-Step Entrance: Ubiquitous in older row houses. A permanent ramp might not be “readily achievable,” but a portable threshold ramp often is. It’s a simple fix too many overlook.
• Restroom Retrofit Puzzles: Squeezing an accessible stall into a 5’x7′ bathroom carved out of a 1910 building is often structurally or financially unfeasible. Sometimes, the solution is creating a single-user, all-gender accessible restroom elsewhere on the same floor, if space allows.
• Elevator Exceptions: Buildings under three stories or with less than 3,000 square feet per floor generally don’t need an elevator installed for barrier removal. But if you’re renovating the path of travel to a second-floor primary function area, you might be required to make the existing elevator compliant.

Making a Practical Plan: Assessment Before Action

You can’t manage what you don’t measure. The first step for any owner of a pre-1993 building is not construction—it’s a professional ADA assessment, often called a CASp report (Certified Access Specialist). This gives you a prioritized list of barriers, an evaluation of what’s readily achievable, and, critically, it provides a “safe harbor” of good faith effort if a complaint is ever filed.

Based on typical projects we consult on, here’s a rough framework for thinking about costs and approaches. Remember, these are ranges—your building is unique.

Barrier & Typical Pre-1993 Challenge	“Readily Achievable” Approach (Lower Cost)	“Alteration-Triggered” Requirement (Higher Cost)	Key Trade-Off / Consideration
Main Entrance (Single Step)	Portable threshold ramp; door hardware replacement.	Permanent ramp with proper slope/landings; automatic door opener.	Permanent ramps need significant space. In tight DC lots, a lift may be the only option, which increases maintenance.
Interior Restroom	Add grab bars, accessible signage, insulate pipes under sink.	“Toilet compartment” approach or full gut to create compliant stall.	Full compliance often requires moving walls/plumbing. The 20% path of travel cost cap is a crucial check here.
Parking	Re-stripe existing lot to create compliant space with access aisle.	Resurface or re-grade lot to achieve proper slope (<2%).	Existing lot slope is a huge factor. A “compliant” space on a 4% slope isn’t compliant at all.
Internal Route (Narrow Hallways)	Remove protruding objects, improve lighting, adjust carpet pile.	Widen hallway to 36″ minimum, which may involve structural work.	This is often the deal-breaker in alterations. The cost to move load-bearing walls can be astronomical.

When to Call a Professional (And Why You Probably Should)

Look, we’ve seen talented contractors try to navigate this with a PDF of the ADA Standards. It usually ends with a costly correction. You need someone who speaks both the language of construction and the legalese of accessibility. A professional doesn’t just check boxes; they help you develop a phased, defensible strategy that aligns with your business goals and budget.

If you’re in the DC area, especially in an older building, and you’re planning any change—a new lease, a refresh, even just wanting to reduce liability—get an assessment. For folks in places like Silver Spring, MD, dealing with their own mix of historic and mid-century buildings, a local pro like Pavel Refrigerant Services who understands Maryland county codes on top of ADA is invaluable. They can spot the intersection of local permitting and federal law that can trip you up.

The goal for pre-1993 buildings isn’t perfection. It’s demonstrable, good-faith progress. Document every step, every decision, and every cost. That paper trail is your strongest defense and the clearest path to making your space welcoming to everyone. It turns a vague, intimidating law into a manageable project plan. And in the end, that’s just good business.
