Why Builders Are Adding Aging-in-Place Features to New Home Plans

The average age of a homebuyer in Georgia is rising. The 55-plus demographic represents one of the most active buyer segments in the state right now, and they are not looking for retirement communities. They are buying new construction homes and asking specific questions about accessibility before they sign contracts.

Builders who are incorporating aging-in-place features into their standard plan offerings are closing more deals with this demographic and spending less time on post-contract modifications. The features are not expensive to build in from the start. They are expensive to add after framing.

What Aging-in-Place Design Actually Means

Aging-in-place design, also called universal design, means building a home that works for people across a range of mobility levels and life stages. It is not about medical equipment or institutional aesthetics. A well-executed aging-in-place home looks identical to any other well-designed home. The difference is in the framing, the door widths, and the layout decisions made during the design phase.

The Demographic Shift Driving This Demand

According to the U.S. Census Bureau, adults 65 and older will outnumber children under 18 in the United States by 2034. In Georgia and North Carolina, retirement-age migration has accelerated this trend. These buyers have equity. They are not stretched on financing. They know what they want, and they do not compromise on the features that matter to them.

The Features That Matter Most

Zero-Step Entry

A zero-step entry means no threshold step at any exterior door. This is the single most requested accessibility feature we see builders adding to plans. It requires attention during foundation design, particularly on slab-on-grade construction where the finished floor elevation relative to the exterior grade must be carefully managed. This is straightforward to detail in the plan and inexpensive to build when designed from the start.

Wide Doorways

Standard interior door width is 32 inches. A wheelchair or walker requires a minimum 36-inch clear opening. Adding 4 inches to every interior door width costs almost nothing during framing. Adding it after framing requires repositioning the rough opening, patching drywall, and replacing the door and casing. At a minimum, ensure the primary bedroom, primary bathroom, and kitchen have 36-inch doors.

Main-Level Primary Bedroom and Bathroom

The most significant layout requirement for aging-in-place buyers. A two-story plan with the primary suite on the upper level does not work for buyers who anticipate eventual mobility limitations. Single-story plans or two-story plans with a main-level primary suite are what this buyer segment wants. This is a plan selection and marketing decision as much as a design decision.

Roll-In or Walk-In Shower

A curbless shower eliminates the step-over threshold that is a fall risk and a mobility barrier. This is a framing and rough-in decision. Specifying a curbless shower in the plan ensures the plumber and tile setter are working from the correct design. Adding it after the fact requires breaking up the slab or subfloor to reposition the drain.

Blocking in Bathroom Walls

Installing solid blocking in bathroom walls at grab bar height during framing costs approximately $50 to $100 per bathroom. Installing grab bars after framing without blocking requires locating studs or using toggle anchors, neither of which provides the structural support required for a 250-pound load. Blocking in the walls does not require installing grab bars now. It means the option is there when needed.

Lever Hardware Throughout

Round doorknobs require grip strength that diminishes with age and arthritis. Lever-style door hardware is easier to operate across a range of hand strength and is the same cost or marginally more than standard knobs.

Wider Hallways

Standard hallway width is 36 inches, which meets code but allows very little clearance for a walker or wheelchair. A 42-inch hallway is significantly more comfortable. Adding width to hallways requires adjusting room dimensions in the plan, which is easier to do at the design stage than after permitting.

What These Features Cost to Add During Design vs. During Construction

• Zero-step entry: $0 in plan design, $500 to $1,500 to add during construction, $2,000 to $5,000 to add after completion
• 36-inch doors: $0 in plan design, $200 to $400 per door to add during framing, $800 to $1,500 per door after drywall
• Curbless shower: $0 in plan design, $500 to $1,000 to add at rough-in, $2,000 to $4,000 after tile is set
• Wall blocking for grab bars: $50 to $100 per bathroom in plan, $500 to $800 per bathroom after drywall

How to Market Aging-in-Place Plans to Buyers

Do not use the phrase aging-in-place in your marketing if your target buyer is under 65. Many buyers in the 55-to-65 range do not identify with that language. They do respond to terms like accessible design, main-level living, single-story convenience, and universal design. List the specific features. Buyers looking for these features will find them.
