Methodology

Home Access Lab creates early estimates for comparing scenarios, not guaranteed prices. Every calculator shows its structure, inputs, and limitations. Cost allowances are broad national planning ranges and should be replaced with local measurements, conditions, and bids.

How we review

• We prioritize official U.S. sources for programs, standards, and data.
• We separate ADA reference material from local residential requirements.
• We do not make diagnoses or clinical recommendations.
• We show review dates and correct links or assumptions when they change.
