Wheelchair Ramps: Complete Homeowner Guide
Updated June 2025 — Permanent, modular, and portable options
The Critical Measurement: Rise and Run
Every ramp decision starts with two measurements: rise (the vertical height from ground to door threshold) and run (the horizontal distance available for the ramp). The ADA slope standard of 1:12 (one inch of rise requires one foot of run) is the universal benchmark for wheelchair accessibility. Steeper slopes (1:10 or 1:8) may be used in very tight spaces but require more effort to self-propel and are not recommended for manual wheelchair users without assistance.
Example: A front door entry that is 24 inches above grade requires a ramp at least 24 feet long (at 1:12 slope). If you only have 12 feet of available run, a switchback ramp with a landing may be the solution.
Ramp Types Compared
| Type | Best For | Cost Range | Permit? | Portable? |
|---|---|---|---|---|
| Portable folding ramp | Occasional use; travel; short rises (up to 6") | $80–$300 | No | Yes |
| Threshold ramp | Door threshold transitions (1–4") | $20–$80 | No | Yes |
| Modular aluminum system | Residential entry; medium rises (6–36"); semi-permanent | $800–$4,000 | Usually No | Semi (can be disassembled) |
| Wood ramp (pressure-treated) | Permanent residential entry; any rise | $1,500–$5,000 | Yes | No |
| Concrete ramp | Permanent; high traffic; long-term | $3,000–$8,000 | Yes | No |
Permit Requirements
Portable and modular ramps: no permit required in virtually any jurisdiction. Permanent ramps (wood or concrete attached to the structure): building permit required in nearly all states. The permit process for a residential ramp typically involves submitting a simple plan showing dimensions and slope, paying a fee ($75–$250), and scheduling a post-construction inspection. See our detailed ramp permit guide.
HOA Restrictions
If your HOA has rules about front-yard modifications, they cannot legally prevent you from installing a disability-related ramp. The Fair Housing Act's reasonable modification provisions override HOA CC&R restrictions. See our full guide: HOA denied my wheelchair ramp — what are my rights?
Ramp Width and Landing Requirements
- Minimum ramp width: 36 inches clear between handrails (wider is better; 48" allows two-way passage)
- Handrails: Required on both sides for ramps with more than 6 inches of rise or more than 72 inches of run in most building codes
- Top and bottom landings: Minimum 60" x 60" at top (to allow wheelchair to clear door swing) and 60" at bottom
- Edge protection: Curbs, barriers, or extended surface to prevent wheels from slipping off the edge
- Surface: Non-slip; wood must be sealed and have grip strips; aluminum systems have built-in textured surface
A standard residential step is approximately 7–8 inches of rise. Three steps would be roughly 21–24 inches of total rise. At the 1:12 ADA slope, you'd need a ramp 21–24 feet long. If that's not possible in a straight run, a switchback design with a flat landing in the middle can achieve the same rise in less linear distance. A modular aluminum system is often the most practical solution for 3-step entries — it can be configured in an L-shape or switchback to fit most spaces.
Yes. Wheelchair ramps are covered by the VA HISA grant (veterans), USDA Section 504 (rural homeowners), Medicaid HCBS waivers (Medicaid-enrolled individuals with disabilities), and many local programs through Area Agencies on Aging. In some areas, Rebuilding Together and similar nonprofits install ramps at no cost. Use our free planner tool to identify programs for your situation.
