Universal Design: Zero Barrier Entry

So you’ve found your property and know that you want to build a Universally Designed structure on it. Maybe you’re building your custom dream home and want to know that you’re going to be able to stay in it as you age. Maybe you’ve just been told you have a progressive condition and you’re going to eventually need a wheelchair, will eventually lose your hearing or will slowly go blind over the next few years. Maybe you have a young child with a disability who will eventually want to have independence within their home. Or maybe you’ve lived with these types of disabilities for years and are simply counting down the days until your home is fully functional for yourself.

Unless you’re in the final category, it’s likely that while you may be thinking about accessibility, the nitty gritty details of what design elements will matter may or may not be front and centre in your mind. Building on the Seven Principles of Universal Design, over the next few weeks we’re going to dig in to some specific design examples. First up – Zero Barrier Entry.

Zero Barrier Entry

Anyone who has ever tried to bump a stroller up six steps, move a heavy piece of furniture up to a second story entrance or help their chihuahua in and out of the house will know that entries to homes can be a huge barrier for everyone involved. If you add in having Grandma to visit at 92 or helping your partner back from the hospital after breaking their leg you start to get the picture. Zero barrier entry makes sure that everyone can get in and out of the house easily and safely. Zero barrier entry creates Equitable Use (Principle 1), is Simple and Easy to Use (Principle 3), provides Perceptible Information (Principle 4), good Tolerance for Error (Principle 5), and Low Physical Effort (Principle 6).

Design requirements:

  • At grade entry for all units OR
  • Ramped entry of 36″ (minimum) to 48″ (preferable) width for Size and Space for Approach and Use (Principle 7) at a 1:12 ratio slope with railings on BOTH sides for Equitable Use (Principle 1) OR Porch Lift/Elevator Entry (may be necessary for building with entries at different grade levels, or for properties where size is a constraint)
  • Optional: ramp/elevator WITH stepped entry for Flexibility in Use (Principle 2)
  • Zero barrier door sill that opens 36″ (minimum) to 48″ (preferable) wide for Size and Space for Approach and Use (Principle 7)
  • Minimize clutter around the door (Principle 7) and a bench beside the door for Equitable Use (Principle 1) to place packages on while opening door, or sit on while waiting for the door to be answered.
  • Use lever handles in contrasting colours to the door for Equitable Use (Principle 1) for ease of opening.
  • Covered porch to allow residents and visitors time to enter and exit the building at their own pace in inclement weather creating Equitable Use (Principle 1).
