Loophole City

Michael DiLucchio

Nashville is one of the fastest-growing cities in America. Most people who live here experience the consequences of that growth every day without understanding where it came from. Loophole City investigates the decisions, documents, and people behind the city most Nashvillians live in without knowing how it got that way. Each season digs into a different chapter of Nashville's development history — told through primary sources, secondary research, and the specific human choices that shaped the city you're living in right now.

    Tall & Skinnies Ep 3: Missing Rung

    In the final episode of Loophole City, we stop looking backward—and ask the only question that matters now: What can Nashville build next? For decades, Nashville’s growth has been shaped by a loophole: two big homes on one lot, over and over again. But between the single-family house and the downtown tower, there’s a missing rung on the housing ladder—triplexes, fourplexes, cottage courts, and other “house-scale” buildings that add more front doors without changing the feel of a street. To figure out what it would take to build that middle on purpose, we follow three case studies from places that went first: ​Prairie Queen (Nebraska): a full neighborhood built almost entirely out of missing-middle housing—designed to look like houses, but quietly hold multiple homes.​Portland (Oregon): what happens when a city legalizes the middle rung in existing neighborhoods—and tracks what actually gets built.​Sacramento (California): a brand-new approach that rewards form over unit counts, and tries to shift the math toward more smaller homes.Then we come home to Nashville: what Metro passed on December 4, 2025, what RN/RL and DADUs actually change, and why the stretch between now and April 2026 is the pivot point—when new zoning becomes lines on a map, and lines on a map become politics on your block. This isn’t an episode about “build everything” or “build nothing.”It’s about directing development—so the city stops growing by loophole, and starts growing by design. Because the next chapter of Nashville isn’t just being written by developers or planners. It’s being written by whoever shows up.

    Tall & Skinnies Ep 2: The Machine

    Nashville’s tall-and-skinnies didn’t arrive because someone “planned” them. They arrived because the system rewarded a blueprint: find the loophole, file the paperwork, build through it. Episode 2 The Machine traces the rise of the HPR loophole—from the 1963 Horizontal Property Act (written for condos), to the 1990 tweaks that made it easier to “turn the key,” to the 2001 Attorney General opinion that officially declared HPRs are not subdivisions—meaning the biggest chokepoint for public pushback and cost could be bypassed. Then the economics catch up. COMZO’s zoning legacy keeps Nashville neighborhoods low-density, but downtown demand flips when a mayor bets on an arena and changes what it means to live in the core. With legal keys in hand and demand in the market, developers begin iterating—neighborhood by neighborhood—until the HPR becomes the dominant unit type reshaping Nashville’s infill development This episode follows the timeline. Ultimately discovering what we gained, what we lost, and why the loophole that was once “affordable” drifted into something else entirely. Primary Research: A Note on Sources The analytical framework for this episode — including the four-era structure of Nashville's HPR development, the legal mechanics of the Horizontal Property Act, the significance of the 1990 amendments, and the data showing more than 20,000 HPR units built from 2010–2023 — draws substantially from the research of Charles Gardner and Alex Pemberton.
