Plans Filed for Mama Hattie’s House, a Supportive Housing Project in Overtown Miami

A meaningful new housing project is moving forward in Miami’s historic Overtown neighborhood. Plans have officially been filed for Mama Hattie’s House, a seven-story, 88-unit affordable development proposed for 430 NW 9th Street. Designed to serve vulnerable young women—specifically those aging out of foster care or rescued from human trafficking—the project also includes 17,280 square feet of office and academic space for Girl Power Rocks, Inc., the nonprofit organization behind the initiative.

The development is planned for what is currently a vacant lot. Once complete, Mama Hattie’s House will offer more than just shelter—it will provide a stable, supportive environment with onsite services tailored to help its residents heal, grow, and thrive. Girl Power Rocks had set out to raise $25 million to bring the project to life, highlighting the community’s deep investment in this mission.

A Tribute to Mama Hattie

The building is named in honor of Hattie Williams—known lovingly as “Mama Hattie”—a longtime community leader in Overtown who dedicated her life to mentoring at-risk youth. She was a mother figure to many, offering guidance, love, and structure to girls navigating extremely difficult circumstances. This new project is a tribute to her legacy, continuing her life’s work in the neighborhood she called home.

Designed with Purpose

The project’s architectural design is being led by REPRTWÄR, a Miami-based firm known for its innovative, community-focused work. The design for Mama Hattie’s House incorporates housing alongside academic, administrative, and wellness spaces, creating a cohesive environment where young women can access the tools and support they need under one roof.

Girl Power Rocks, Inc. has long been a driving force for change in Miami, offering girls ages 11 to 17 programs focused on academic support, counseling, self-esteem, and leadership development. With Mama Hattie’s House as its future headquarters, the organization will be able to expand its impact and offer on-site services to girls in urgent need of both housing and healing.

Community and Context

Located at 430 NW 9th Street, the site sits in a highly accessible part of Overtown, close to public transit, the Health District, and Downtown Miami. Its central location ensures residents will have access to essential services while remaining rooted in a neighborhood with deep cultural and historical significance.

By filing for administrative site plan review, the team has taken the next step toward making this vision a reality. If approved, Mama Hattie’s House will become a vital resource in the community—one that not only provides housing, but helps rebuild lives, restore dignity, and honor a legacy that still inspires.
