🍲Chapter 5: Kitchens

Lots of detail goes into a universally accessible kitchen. These universal design features provide easy access and usability for everyone.

Residential Universal Design Building Code, 2024 version. Β© The UD Project.

Section 5.1: Easy Access

5.1.1 Floor space in front of appliances and counters β‰₯ 48 inches.

At least 48" (122cm) of floor space should exist in front of any appliance and counter.

This provides room for moving around easily while carrying items (such as dishes) and is necessary for people who use mobility equipment. Sometimes, the space in front of an appliance will extend into a hallway or another room. That’s okay as long as the floor space is unobstructed.

5.1.2 Space between appliances and corners β‰₯ 18 inches.

At least 18" (46cm) of space should exist between appliances and corners.

It’s easy to get β€œstuck” in a corner when trying to reach something if space to move around is limited, especially for anyone who uses a wheelchair, walker, crutches, or a cane.

5.1.3 Turning radii β‰₯ 60 inches.

There should be a 60" (152cm) turning radius in every workspace (most kitchens include multiple workspaces) that extends floor-to-ceiling when all cabinets and appliances are closed.

This will allow anyone who relies on extra support to move around easily without bumping into walls or appliances. While this is accommodating to wheelchairs, it also provides breathing room for people carrying items or for two or more individuals working in the same area.

Cabinet hardware and appliances should not extend into this space, even when doors are closed.

5.1.4 Prep areas with under-counter clearance next to each workspace.

Each workspace should have a prep area adjacent to it with at least 29" (74cm) of vertical under-counter clearance. This primarily includes the sink and the cooktop but may include other workspaces depending on kitchen configuration.

Many people perform tasks better when seated. Under-counter access is imperative to allow for optimal ergonomics. See Section 5.2 and Section 5.3 for more info.

5.1.5 Unconventional and adequate storage.

A universally accessible kitchen must accommodate as much storage as found in typical kitchens of the same size without full dependency on cabinets.

See Section 5.6 for more details.

Universal design requires an unconventional approach due to the need to accommodate people with different reach ranges and those who perform tasks better when seated. This inherently reduces the amount of storage space found in typical kitchen cabinet configurations that (1) fill all the under-counter space and (2) take advantage of vertical space that often requires a step stool to access.

The simplest option is to include a large walk-in pantry with a β‰₯ 32" (81cm) entrance.

5.1.6 Kitchen next to eating areas.

The kitchen should be adjacent to an eating area.

This is about convenience and ease of use by providing minimal distance for moving food and dishes between spaces. It’s helpful for anyone, though it becomes an incredibly useful feature if someone has fatigue or uses a mobility device.

Section 5.2: Sinks

5.2.1 Top of sink: 36 inches from floor.

Sinks in kitchens should be 36" (91cm) from the floor. This measurement is from the floor to either the top of the counter or the top of the sink, whichever is highest.

Adjustable-height counter exception:

Adjustable height counters with a minimum range of 30-42" (76-107cm) may be used instead of a fixed counter/sink height.

5.2.2 Under-sink clearance: β‰₯ 29 inches from floor.

The sink must have at least 29" (74cm) of unobstructed vertical clearance underneath for seated access. This should be measured from the floor to either the bottom of the counter or the bottom of the sink, whichever is the lowest, based on the style of the sink.

The goal of 5.2.2, 5.2.3, & 5.2.4 is to provide access for users who prefer to or need to sit on a chair, stool, wheelchair, or another mobility device at the cooktop. This way, anyone has the opportunity to conserve energy and/or improve ergonomics while cooking.

Dual-sink exception:

If dual sinks are used, one deeper sink that extends into the under-sink vertical clearance may be used, but the side-to-side clearance and depth clearance under the shallow side must exist, as described in 5.2.3 and 5.2.4.

5.2.3 Under-sink clearance: β‰₯ 32 inches side-to-side.

The sink must have at least 32" (81cm) of unobstructed horizontal clearance underneath.

Offset drains:

Sinks with drains offset to the side may work well, though the plumbing should not obstruct this width or depth as described in 5.2.4.

5.2.4 Under-sink clearance: β‰₯ 18 inches of depth.

The sink must have at least 18" (46cm) of unobstructed depth clearance underneath.

Offset rear drain:

Sinks with drains offset to the rear are ideal.

Cabinetry exception:

Under-sink clearance can be achieved with closed cabinetry with flipper doors that fully recess. The width between open doors must still be β‰₯ 32" (81cm), and the flooring should extend to the wall underneath.

Plumbing exception:

The drain pipe from the sink may extend into the under-sink clearance only if located exactly in the middle of the 32" (81cm) clearance width so knees can go around it. Garbage disposals should not be used unless installed β‰₯ 18" (46cm) from the front edge of the counter.

5.2.5 Insulated and padded plumbing.

Any exposed plumbing needs to be insulated and padded.

This protects against exposure to high temperatures and/or reduces leg injury when someone is seated at a sink.

Unexposed plumbing exception:

If plumbing is unexposed behind a panel, it does not need to be insulated and padded.

5.2.6 Easily manipulated faucet hardware.

Faucet hardware should be operable with one hand while not requiring pinching or grasping.

No pulling, turning, or gripping should be required, which will make faucets easy to use for everyone, but particularly for users who struggle with dexterity.

Type:

Motion-activated faucets, single-touch faucets, as well as those with single-handle lever-based hardware are all ideal.

5.2.7 Temperature indicator on the faucet.

Faucet hardware should have clearly visible hot and cold temperature indicators.

While it's generally expected that hot is to the left and cold is to the right, this isn't intuitive for everyone. Clearly visible indicators enhance safety. Consider using both colors and letters/words to depict between hot or cold temperature controls.

5.2.8 Side-mounted faucet.

Faucet mounted at the side of the sink (vs. the rear).

If the faucet is installed to the side of the sink instead of the rear, it will require less reach. This is ideal for kids and anyone who needs to access the sink while sitting.

Filling pots:

If possible, choose a faucet that can rotate over a counter next to the sink to fill a pot.

5.2.9 Spray faucet.

Pull-out spray faucet -or- faucet with side spray.

Pull-out spray faucets or side sprays next to faucets are a great way to increase the flexibility of use for the sink. They’re convenient and handy for situations that benefit from water streaming from a different position than straight down from a faucet, such as washing veggies, cleaning dishes, or refilling a coffee maker.

Filling pots:

If possible, choose a faucet with a hose that's long enough to reach beyond the sink to fill a pot sitting on the counter.

Grip:

Spray faucets should not require a strong one-handed grip to remove. Be mindful of this when looking at product options.

5.2.10 Disposal switch ≀ 12 inches from the front of the counter.

If a garbage disposal is used, its switch should be no more than 12" (30cm) from the front edge of the counter.

Disposal switches should be wall-mounted, counter-mounted, or just under the counter on a cabinet. Regardless of location, they need to be easy to reach for anyone.

Section 5.3: Cooktops & Ovens

5.3.1 Induction cooktop.

The cooktop should be induction, with front or side-mount controls that are easy to operate and can be locked.

Induction cooktops are smart for universal design because they reduce the potential for burns significantly. Heat transfer occurs through a magnetic field, which means that the "burners" (elements) are never hot to the touch. Induction cooking is faster and more energy-efficient than typical electric surfaces and allows instant control of cooking power, similar to gas. Furthermore, induction cooktops are generally easy to clean, as the surfaces are flat.

Controls:

Many cooktops and ranges have rear-mounted controls, requiring extra reach over potentially hot surfaces or cookware. Controls on the front or side provide more safety than rear controls.

Look for cooktops with controls that can be locked and that don't require a grip to operate (e.g., avoid knobs that simultaneously require pushing and turning).

5.3.2 In-counter cooktop.

This provides the most flexibility for people to access the cooking area safely. In-counter installations allow for under-counter clearance. The goal is to provide access for users who prefer to or need to sit on a chair, stool, wheelchair, or another mobility device at the cooktop.

5.3.3 Pot filler above the cooktop.

A pot filler that reaches above all heating elements should exist above the cooktop with water controls mounted on the counter that comply with 5.2.5.

Pot fillers reduce the effort needed to fill a pot or pan with water at the sink and safely move the cookware to the cooktop.

Exception:

If the cooktop is near the sink, a pot filler may be excluded if the sink faucet or side spray can be used to fill a pot sitting on a counter between the cooktop and the sink.

5.3.4 Under-counter clearance: β‰₯ 29 inches from the floor.

The cooktop must have at least 29" (74cm) of unobstructed vertical clearance underneath for seated access. This should be measured from the floor to either the bottom of the counter or the bottom of the cooktop, whichever is the lowest.

5.3.5 Under-counter clearance: β‰₯ 32 inches side-to-side.

The cooktop must have at least 32" (81cm) of unobstructed horizontal clearance underneath for seated access.

5.3.6 Under-counter clearance: β‰₯ 18 inches of depth.

The cooktop must have at least 18" (46cm) of unobstructed depth clearance underneath for seated access.

Cabinetry Exception:

Under-counter clearance can be achieved with closed cabinetry with flipper doors that fully recess. The width between open doors must still be β‰₯ 32" (81cm), and the flooring should extend to the wall underneath.

5.3.7 Vent/hood switch ≀ 12 inches from the front of the counter.

The switch to turn an exhaust fan and/or light should be no more than 12" (30cm) from the front edge of the counter.

Switches that control the exhaust fan in a vent or hood should be wall-mounted, counter-mounted, or just under the counter on a cabinet. Regardless of location, they need to be easy to reach for anyone.

5.3.8 Wall oven with a side-swing door.

The oven should be a wall oven with a side-swing door, with the lowest inside surface between 36-42" (91-107cm) from the floor.

Wall ovens installed in custom cabinetry are ideal for increased access and usability because they can be mounted at user-friendly heights. This will eliminate the requirement for most users to bend down to reach into the oven, which is safer and easier on everyone’s backs. The oven door should swing open to the side instead of folding down.

5.3.9 Microwave on the counter -or- in-wall or cabinet.

Microwaves should have a permanent location on the counter -or- in a wall or a cabinet. The inside surface should be between 36-42" (91-107cm) from the floor.

Microwaves can be surrounded by cabinetry or placed directly on the counter. The inside should be reachable for users who are seated, as well as for kids or adults of shorter stature. The common placement of the microwave above the stove is one of the most difficult locations for accommodating the widest range of users and reach ranges.

5.3.10 Pull-out shelves under all ovens.

A pull-out shelf should be installed under each oven (traditional and microwave) with at least 29" (74cm) of unobstructed vertical clearance underneath for seated access.

Pull-out shelves provide a workspace for resting hot items that come out of the oven or microwave. This is a safety feature and is particularly useful for people who navigate kitchens with mobility devices.

Section 5.4: Refrigerators

5.4.1 Space for full-size refrigerator -or- a built-in compact fridge -and- a built-in compact freezer.

Based on our user research, there is no universally accessible full-size refrigerator option. For this reason, a space for a full-size fridge with a water hookup should exist to provide individuals the flexibility to select an option that works best for them.

Alternatively, compact refrigerators and freezers may be installed in a wall or the cabinetry with the lowest inside surface between 36-42" (91-107cm) from the floor. The refrigerator and freezer should be separate units with interior lighting and pull-out shelves.

If possible, designing a kitchen with a built-in compact refrigerator and a built-in compact freezer AND space for a full-size fridge will provide the most flexibility, especially if a household needs more storage capacity.

Pull-out shelves inside provide flexibility in storing and retrieving items. This, along with interior lighting, helps people easily assess and visually identify what is inside.

Section 5.5: Counters

5.5.1 Multiple counter heights.

Counter workspaces should be usable at various heights. First, consider all workspace locations, then plan to use different counter heights for each. The order of priority should be:

  1. Standard height (34-36" / 86-91cm)

  2. Table height (30-32" / 76-81cm)

  3. Bar height (40-42" / 102-107cm)

Adjustable-height counter exception:

Adjustable height counters with a minimum range of 30-42" may be used in lieu of multiple counter heights.

Counter spaces will be more functional for those seated and of shorter stature when installed at a lower level than the standard 36" (91cm) counter height, while taller users and individuals using power wheelchairs benefit from standard height and bar height workspaces. There are countless scenarios when more than one person will use a kitchen space. Universal design is functional for as many people as possible, so the solution is to create a variety of kitchen counter surfaces at different heights.

5.5.2 Durable countertops.

Counter surface(s) should be heat-resistant and chip-resistant.

Our countertops get a beating with all we do in the kitchen. Choose a surface that won’t be damaged by heat or spills. The ability to rest a hot piece of cookware on the counter without worry is not only handy during meal prep but also adds an element of safety to the kitchen.

5.5.3 Rounded corners and edges.

Counter corners and edges should be rounded.

Sharp corners and edges are a safety hazard for anyone who may lose their balance while performing tasks in the kitchen. Rounded corners are also a safety feature for young kids with counter-height heads.

5.5.4 Solid color surfaces with low reflectivity.

Countertops should be solid colors with no patterns or very low contrast patterns and should be minimally reflective.

Small items can visually "get lost" in counters with busy patterns, such as typical with many granite options. High reflectivity can also create difficulty in focusing on various tasks. This is particularly problematic for people with low vision but is something anyone can experience.

Section 5.6: Cabinets and Storage

5.6.1 Storage: β‰₯ 75% between 18-48 inches from floor.

At least 75% of all storage should be located between 18-48" (46-122cm) from the floor. This refers to the height of the top of shelves or drawers.

This reach range will accommodate the greatest amount of users, whether someone is short, tall, seated, or standing. The point is to ensure that most items are within easy reach without using a step stool or putting unnecessary strain on one's back.

Pull-down shelving exception:

If pull-down shelving is used for any cabinet storage over 60" (152cm) from the floor, the 75% requirement may be reduced to 50%.

Walk-in pantry exception:

The 75% requirement may be reduced to 50% if a large walk-in pantry exists.

5.6.2 Pull-out shelving for storage deeper than 18 inches.

Pull-out shelving or drawers should be used in storage areas deeper than 18" (46 cm).

Pull-out drawers/shelves minimize reaching and possible strain by providing easy access to food and kitchenware. People shouldn't need to bend or crawl into a lower cabinet to find what they want. All sorts of options exist, such as shelves that rotate out of a corner cabinet.

5.6.3 Easy-use cabinet hardware.

Cabinet hardware should be usable one-handed & without the need for grip strength.

Use cabinet hardware that requires minimal physical effort, such as D or C-shaped handles and pulls. T-shaped pulls can catch on clothing/etc. Knobs are difficult to use if hand function is impaired. Avoid anything that requires pinching or grasping for use.

The physical actions necessary to open a heavy door or drawer can create difficulty with maintaining balance and can cause frustration or fatigue.

Optional but ideal:

Soft-close cabinetry and pads that lessen the noise of drawers and cabinets can help minimize noise in the kitchen, which is helpful for people who struggle with sensory processing.

Section 5.7: Dishwashers

5.7.1 Easy-reach dishwasher.

The dishwasher should either be a standard-size dishwasher installed in cabinetry at least 8" (20cm) off the floor and/or a drawer dishwasher installed just below the top of the counter.

Dishwashers raised off the floor minimize bending to reach items on the lower rack. A dishwasher installed higher than floor level (versus on the floor) provides the ability to move dishes in and out easily and decreases the distance to transfer them to storage. This should be planned early in the kitchen design, as standard-size dishwashers will rise above the typical 36" (91cm) counter height when elevated.

Drawer dishwashers are also a great option, though their capacity will be less than standard-size options. Similar to the refrigerator drawers, they're less deep and low to the ground than standard dishwashers.

5.7.2 Located next to the sink.

The dishwasher should be located directly adjacent to the sink.

Installing the dishwasher next to the sink is convenient for loading dishes and cookware as quickly as possible during cleanup. It also reduces the steps needed for loading, which is important for people who struggle with organizing and planning tasks in a logical order.

5.7.3 Panel-ready with cabinet pull.

If a dishwasher cannot be opened one-handed with minimal grip strength, a panel-ready dishwasher that accommodates a variety of cabinet pulls should be used.

See 5.6.3: Easy-use cabinet hardware for info about cabinet pulls.

Many dishwashers are extremely difficult for individuals with limited or no grip strength to open. Selecting a panel-ready option with an easy-to-use cabinet pull will solve this frustrating problem.

Section 5.8: Lighting

5.8.1 Task lighting over each workspace.

Task lighting should exist over each workspace. This includes places for tasks such as meal prep, cooking, cleanup, eating, and others.

Task lighting should be above each workspace and added to complement the ambient lighting. This lighting should minimize shadows and be designed to be glare-free. Remember that single sources of overhead lighting can cast shadows on workspaces, especially when a person is between the light source and the area where the person is working.

5.8.2 Ambient lighting that covers paths of travel and eating areas.

Ambient lighting should illuminate all travel paths and areas where people may eat. This should be complementary to task lighting.

Lighting should minimize shadows and be designed to be as glare-free as possible. This is useful for everyone but is especially important for people who rely on visual communication.

Recommended: indirect and low lighting:

Using indirect ambient lighting and low lighting that illuminates the floor without visible bare bulbs or translucent covers (from a seated or standing position) is ideal. Indirect lighting reduces eye strain and is more calming than direct lighting.

The option to adjust the intensity of ambient lighting (e.g., with a dimmer) should be used wherever possible.
