Atlanta has many charming historic Missing Middle Housing types, and we even have a new Missing Middle Housing zoning category to encourage more of it (more on MR-MU later). Atlanta also has many abandoned not-so-charming apartment buildings. While their lack of architectural charm leaves them overlooked, these are important to our city’s housing supply. Why? They, too, are Missing Middle Housing. They, too, are historic. And most importantly: they already exist, making them more affordable to renovate than to build new.
