Montana Home Modifications for Seniors

What the Big Sky Waiver Covers

Montana's Big Sky Waiver (BSW) is the primary Medicaid program that pays for home modifications. Under the "environmental accessibility adaptations" benefit, BSW covers changes that are directly necessary for the senior's health, welfare, or ability to function in the home. This includes:

• Wheelchair ramps and widened doorways
• Grab bars in bathrooms and hallways
• Roll-in showers or tub-to-shower conversions
• Non-slip flooring in wet areas
• Handrails on interior and exterior stairs
• Threshold modifications for wheelchair or walker access

The modifications must be pre-approved through the case management team and documented on the Service Plan (Form SLTC-134). BSW won't cover general home improvements, cosmetic upgrades, or modifications to a rental property without the landlord's written consent. The work must be completed by a licensed contractor, and the state sets cost limits per modification type.

The catch: BSW has a waitlist. With roughly 2,500–2,800 active enrollment slots statewide, not every eligible senior gets in immediately. If your parent is on the waitlist, home modifications through BSW are not available until a slot opens and they're enrolled.

Alternatives When BSW Isn't Available

If your parent isn't enrolled in BSW — either because they're on the waitlist, they don't meet BSW's clinical threshold, or they're paying for care privately — several other programs can help:

HRDC Weatherization and Home Repair. Montana's Human Resource Development Councils administer weatherization and home repair programs using LIHEAP and DOE funds. These programs target low-income homeowners and can include safety modifications like handrail installation, door widening, and bathroom accessibility improvements alongside traditional weatherization work (insulation, window replacement, furnace repair). Income eligibility depends on the specific program and current funding. Contact your regional HRDC — Montana has 12 districts covering every county.

USDA Rural Development Section 504 Loans and Grants. Available to very-low-income homeowners in rural areas (which includes most of Montana outside Billings, Missoula, and Great Falls metro areas). Grants up to $10,000 for homeowners aged 62 and older who can't repay a loan. Loans up to $40,000 at 1% interest for up to 20 years. Both cover home repairs and modifications needed for health and safety.

VA Home Modifications. Veterans may qualify for the Specially Adapted Housing (SAH) grant (up to $126,526 in FY 2026 for service-connected disabilities) or the Home Improvements and Structural Alterations (HISA) grant (up to $6,800 for service-connected, $2,000 for non-service-connected). These don't require Medicaid eligibility.

Tribal Housing Programs. Montana's tribal nations operate housing and elder-services programs that may include accessibility modifications for elders on reservation land. The Confederated Salish and Kootenai Tribes (CSKT) and other tribal nations have elder-services contacts; funding sources include HUD Indian Housing Block Grants and tribal general funds. Availability and scope vary by tribe and budget cycle.

Using Modifications as a Medicaid Spend-Down Strategy

Home modifications can serve double duty for families navigating Medicaid financial eligibility. Under Montana's medically needy spend-down, applicants whose income exceeds $994/month must "spend down" their excess income on allowable medical expenses each month. Home safety modifications that are medically documented — prescribed by a physician or recommended by the Mountain-Pacific assessment — count as allowable expenses.

This creates a strategic opportunity: instead of paying the monthly spend-down obligation as cash to the state, the family directs that money toward modifications that directly improve the parent's safety and reduce fall risk. A grab bar installation, a bathroom modification, or a ramp project can absorb multiple months of spend-down obligations while producing a tangible safety improvement.

For asset eligibility, the math works similarly. The $2,000 asset limit for Medicaid HCBS doesn't count the primary home (up to $752,000 in equity). But excess countable assets — savings beyond $2,000 — can be spent on medically necessary home modifications to reach the asset limit. Unlike most spend-down strategies, this one leaves the family with something permanent and useful rather than simply depleting savings.

Prioritizing Modifications

Not every modification has the same return on safety. For Montana seniors aging in place, the highest-impact changes based on fall and injury data are:

Bathroom first. More falls happen in the bathroom than any other room. Grab bars next to the toilet and inside the shower or tub, a shower chair or bench, non-slip bath mats, and a handheld showerhead address the highest-risk moments of the day.

Entryways and stairs second. Montana's winter weather makes exterior steps and walkways dangerous from October through April. Handrails on both sides of exterior stairs, well-lit entryways, and covered step surfaces that can be de-iced reduce the risk of falls during the months when emergency response times in rural areas are longest.

Lighting throughout. Motion-activated lighting in hallways, bathrooms, and between the bedroom and bathroom reduces nighttime fall risk — a leading cause of hip fractures in seniors. These modifications are low-cost and can be done immediately without waiting for program approval.

The Montana Home Care Navigation Guide includes a room-by-room home safety assessment checklist scored by fall risk priority, along with cost estimates for common modifications and a funding source matrix that matches your parent's situation (Medicaid, VA, HRDC, tribal, or private pay) to available programs.
