Despite the substantial impact of the ADA legislation, people with disabilities (PwD) still encounter significant barriers in public building accessibility that severely hamper equitable Community Living and Participation. One solution is to make building accessibility ratings publicly available, but to date, this information has been virtually nonexistent. This project, based at the R2D2 Center and in collaboration with the Universities of New Mexico, Columbia, Marquette and IndependenceFirst will infuse NIDILRR-supported Access Ratings for Buildings apps (ARB) into urban/suburban and rural communities. The goal of this project is to conduct knowledge translation activities for the ARB app suite to improve community participation for PwD through the successful implementation of a novel building accessibility rating system, developed over the past decade and ready for community rollout. Objectives of this study are: 1) Prepare for community rollout of the ARB app suite through targeted training and toolkit development; 2) Pilot 3 ARB community engagements; 3) Rollout the ARB package into 33 focal communities; and 4) Evaluate success of the use and implementation of the rollout with community stakeholders. Outcomes include: 1) PwD using helpful accessibility ratings about public buildings with a 75% saturation rate of restaurants, 2) Successful model of community intervention for replication in additional locales, 3) Better community participation for PwD, 4) Improved advocacy and awareness of community accessibility, 5) Dissemination of high impact papers. Products of the ARB project include: 1) An updated ARB app suite for community rollouts, 2) A community engagement ARB Rollout Toolkit, 3) Demonstrated adoption of the ARB app ratings in 33 communities, and 4) Evidence of successful ARB Community Rollout.
