If you live in Knox County, Tennessee—whether in Farragut, Powell, Hardin Valley, or out in the rural parts—you’ve likely heard whispers (or full-on discussions) about the UDO. Short for Unified Development Ordinance, it’s the biggest update to how our county grows and develops in decades. As of late March 2026, the draft zoning map and proposed standards are out for public review, with community meetings happening right now. Here’s a clear, no-jargon breakdown of what’s going on and why it matters to everyday Knoxvillians and county residents.
First, a Quick Backstory: Advance Knox
The UDO isn’t coming out of nowhere. It’s the final phase of Advance Knox, Knox County’s community-driven effort to update its land-use and transportation plans. The Comprehensive Land Use and Transportation Plan and Growth Policy Plan were adopted in 2024 after years of public input. Those plans outlined a vision for sustainable growth: directing new development to areas with existing infrastructure, protecting natural resources, supporting more housing choices, and making sure roads, schools, and services can keep up.
Now comes the UDO—the “how” part. It turns that big-picture vision into actual, enforceable rules.
What Exactly Is a Unified Development Ordinance?
Right now, Knox County’s development rules are scattered across multiple old documents: the zoning ordinance (some parts dating back to the late 1960s/early 1970s), subdivision regulations, street standards, stormwater rules, and building/fire codes. That patchwork creates confusion, delays, and inconsistencies for homeowners, developers, and even county staff.
The UDO puts everything into one modern, user-friendly document. Think of it as a single rulebook instead of a messy stack of overlapping manuals. It covers:
• Zoning districts and uses
• Street and subdivision design
• Stormwater management
• Landscaping, signs, and site standards
• Building and fire codes
The goal? Streamline the process, remove ambiguity, increase predictability, and make sure new development actually supports the community vision from Advance Knox. No more developers clearing every tree with minimal requirements or neighborhoods with dead-end streets and poor connectivity.
Why This Matters for Knox County Residents
Unincorporated Knox County’s population has grown 160% since 1970. We need housing that fits different budgets and lifestyles, better infrastructure investment, and protection for our ridges, valleys, farms, and scenic areas. The UDO aims to deliver that by:
• Updating zoning names and standards to match the new “place types” in the comprehensive plan.
• Encouraging mixed-use development along corridors where it makes sense.
• Requiring better design standards for compatibility between homes, businesses, and neighborhoods.
• Promoting neighborhood connectivity and true open space (not just a detention pond with no trees).
For property owners: Most changes will be minimal. Your current use stays the same. The draft map mostly updates district names, and in areas with good infrastructure, it may allow more housing options or mixed-use to align with the plan. Any rezoning only applies to future development—not what’s already there.
Where We Stand Right Now (March 2026)
The project team just released:
• Draft dimensional standards for the proposed new zoning districts (with an explanatory video).
• Draft zoning map with an interactive tool so you can look up your property and compare current vs. proposed zoning.
Public comment deadline: Sunday, April 5, 2026.
Ongoing public meetings (drop in anytime—no formal presentation):
• Today, Tuesday, March 31: 11 a.m.–1 p.m. at Three Ridges Golf Course and 4:30–6:30 p.m. at Powell Library.
• (Yesterday’s events at Northshore and New Hopewell Elementary wrapped up strong.) I stopped in the Northshore meeting.
There’s also a virtual lunch-and-learn on Thursday, April 2 at noon covering landscaping, signs, and stormwater (registration required; recording will be posted).
All past meeting materials, videos, and drafts are already online. Once the full draft UDO is ready, there will be more in-person meetings before final adoption (targeted for mid-2026).
How to Get Involved
Head to advanceknox.org/udo right now:
• Review the draft map and standards.
• Use the interactive zoning viewer.
• Fill out the feedback survey.
• Leave comments or read what others are saying.
Whether you want more housing options near jobs and transit, worry about preserving rural character, or just want clearer rules so your neighbor’s addition doesn’t become a headache—the UDO will shape Knox County for the next generation. This is your chance to weigh in while the drafts are still open.
Knox Planning (the team formerly known as the Metropolitan Planning Commission) and Knox County have done a lot of outreach already, but turnout at these final meetings matters. Drop by one of today’s events if you can, or jump online before April 5.
The UDO won’t solve every growth challenge overnight, but it’s a big step toward smarter, fairer, and more predictable development that reflects what Knox Countians actually told planners they want.
