This RFP calls for the design, development, implementation, and three‑year annual maintenance of a cloud‑hosted, SaaS/custom‑off‑the‑shelf system to manage Tennessee’s manufactured‑housing and codes‑enforcement programs. The solution must support multiple user portals (state staff, inspectors, plan examiners, county clerks, public, etc.), provide role‑based access, offline inspection forms, route optimization, extensive reporting, payment processing, integration with Active Directory and the State’s Core permitting system, and meet stringent security standards (FIPS, NIST, ISO, FedRAMP, PCI‑DSS). The State will retain a perpetual, non‑exclusive license and ownership of all custom‑developed code, with a base contract term of 36 months and two optional 12‑month extensions (up to 60 months total). • Develop and configure a multi‑portal web application with mobile inspection capability. • Integrate with State Active Directory, Core licensing system, and merchant‑services provider for PCI‑DSS‑compliant payments. • Deliver data migration, training, UAT, go‑live support, and three years of ongoing SaaS hosting, maintenance, and support. • Provide 99.5 % application availability, on‑shore data storage, audit‑trail, backup/recovery, and annual licensing fees for back‑office, portal, and mobile modules. • Follow a phased payment schedule tied to 11 implementation milestones and annual recurring license/hosting fees.
