Taipei is the most densely-populated city in Taiwan. It’s showed us a great deal of the need of housing rental. With this matter, the Taipei City Government announced the "Taipei housing policy" in October 2010 and officially to open application "Taipei public housing" in 2011. Taipei City Government's "public housing" policy is expected from 2011 to 2014 to be completed or planning to build a total of about 5,000 households in rented public housing. Promoting rationalized real estate rental market, improving living and environmental quality, and to offer the better public housing to care for vulnerable. Through literature review and the investigation, 6 major-oriented and 26 secondary evaluation indicators were proposed. Using the Analytic Hierarchy Process (AHP) survey research methods, we know that nearing the mass transit system, job market and living space planning are the most important factors of the policy. I hope the conclusion of this study could be submitted as reference material of public rented housing policy, as well as give a significant suggestion to the Taipei City Government in the future.
