Sevier County Zoning Rewrite Clears Planning: Hillside Overlay, Critical Slope Rules, and a Five-Foot Firewise Zone

Sevierville Regional Planning unanimously recommended a comprehensive rewrite of Sevier County zoning regulations. Staff said the largest changes are the critical-slope and hillside overlays, plus a new five-foot Firewise zone around building envelopes. The package now goes to County Commission.

Unincorporated Sevier County is looking at the biggest zoning rewrite in years. At a Sevierville Regional Planning Commission meeting recorded in the city’s Sept. 3, 2026 minutes packet, Development Director Corey Divel told commissioners the package is “a large rewrite with the most significant changes being related to critical slope overlay and the hillside overlay protection.” County Planning Director James Temple, Jr. walked through the details, and the commission voted unanimously to recommend approval to the Sevier County Commission.

Citizen Portal’s Sept. 3 summary dates that recommendation to an Aug. 6 meeting. The minutes packet that carries the unanimous vote is filed under the Sept. 3 agenda-center ID. Both versions are listed below so readers can see the date conflict.

For anyone who owns acreage, a cabin site, or a hillside lot outside Sevierville, Pigeon Forge, Gatlinburg, or Pittman Center, this is the rulebook that controls how much of a steep lot can be disturbed, how site plans are sequenced, and where a five-foot Firewise clearing sits around a building envelope.

What the rewrite changes

Staff framing	Large rewrite; biggest changes are critical-slope and hillside overlays	Divel, minutes
Review time	About two years of review, per Temple	Minutes
Site plans	Conceptual, preliminary, and final site-plan procedures clarified	Minutes
Slopes	Updates to critical-slope and hillside overlay regulations; new mapping for those districts	Minutes

Other	Driveway and parking grades; vesting-right provisions; online zoning maps expected	Minutes
PC action	Unanimous recommend-approval to County Commission	Minutes

Hillside and critical-slope overlays

Temple told the commission the rewrite updates critical-slope and hillside overlay regulations and creates new mapping for those overlay districts. Divel singled those overlays out as the most significant changes in the package.

That matters on mountain roads where a “buildable” acre on paper may sit on 25% to 40% slopes. Overlay rules usually limit how much of a lot can be graded, where driveways can climb, and which parts of a parcel stay undisturbed. If you are pricing a vacant lot above the valley floor, ask for the overlay map that will apply after County Commission acts, not only today’s base zoning color.

Temple also said driveway and parking grades are being revised. On a steep Sevier County site, grade limits can decide whether a second cabin pad is realistic or whether the engineer has to redesign the entrance.

The five-foot Firewise zone

The minutes say the rewrite creates a five-foot Firewise zone around building envelopes. Firewise setbacks are meant to keep burnable brush and debris away from the structure. On a wooded cabin lot, that can mean clearing a ring that buyers and insurers will expect to see maintained.

It is a small number on the page and a real maintenance chore on the ground. Owners who already keep a tidy envelope will notice less change than owners who have let undergrowth run to the foundation line.

Site-plan steps and online maps

Temple described consolidation and clarification of site-plan requirements, including conceptual, preliminary, and final site-plan procedures. For a small builder or a landowner who wants three cabins, that sequencing is the difference between one hearing and three. Vesting-right provisions and related development standards were updated as well.

He also said zoning district maps are expected to be made available online. Until those maps are live, treat any verbal description of a hillside or critical-slope line as provisional and ask Planning for the exhibit that will accompany the County Commission packet.

Where the meeting date differs

Two public records describe the same recommendation with different meeting dates:

Sevierville Regional Planning Commission minutes (Agenda Center file dated Sept. 3, 2026) record Divel’s and Temple’s presentation and a unanimous vote to recommend approval to the County Commission, on a motion by Mayor Fox seconded by Mr. Patterson.
Citizen Portal’s Sept. 3, 2026 article says the Sevierville Regional Planning Commission on Aug. 6 recommended approval of the comprehensive rewrite.

Neither source, in the text opened for this article, shows a final County Commission adoption date. Until commissioners vote, the rewrite is a recommendation, not the law on the books.

What it means for Smokies homeowners

City lots inside Sevierville, Pigeon Forge, Gatlinburg, and the other municipalities keep their own zoning. This package is aimed at the unincorporated county and the planning region the Sevierville commission reviews.

If you own hillside land, three questions are worth asking before you list or before you buy next door:

Does the new hillside or critical-slope map cover your parcel, and how much disturbed area would it allow?
Will the five-foot Firewise zone around the building envelope force clearing you have not budgeted?
If you planned a multi-cabin site plan, which conceptual / preliminary / final steps will you owe under the clarified procedures?

Answer those with the county’s exhibits, not with a neighbor’s memory of old rules. A buyer’s inspector and a lender’s underwriter will eventually ask the same questions.

Until County Commission votes, treat marketing language that assumes the new overlays are already law as premature. Ask for the packet exhibits that will accompany the commission item, including the hillside and critical-slope maps Temple said would be updated.

Key dates

About two years of review — Temple’s description of how long the rewrite had been in process.
Aug. 6, 2026 — Citizen Portal’s date for the Planning Commission recommendation.
Sept. 3, 2026 — Agenda Center minutes file that records the unanimous recommend-approval vote.
Next — Sevier County Commission action on the revised regulations (date not stated in the opened minutes or Citizen Portal summary).

The commission voted unanimously to recommend approval of the revised Sevier County Zoning Regulations to the County Commission, according to the Sept. 3, 2026 minutes packet.

What are the biggest changes in the Sevier County zoning rewrite?

Development Director Corey Divel said the most significant changes are related to the critical slope overlay and the hillside overlay protection. Temple also described a five-foot Firewise zone around building envelopes.

Does the five-foot Firewise zone apply inside Sevierville city limits?

The item on the Planning Commission agenda was an amendment to Sevier County Zoning Regulations for the county / planning region. City zoning inside Sevierville, Pigeon Forge, Gatlinburg, and other municipalities is separate.

When does the rewrite take effect?

The opened minutes and Citizen Portal summary show a Planning Commission recommendation to County Commission. They do not state a final County Commission adoption or effective date.

Why do two sources list different meeting dates?

Citizen Portal’s Sept. 3 article says the recommendation happened on Aug. 6. The Agenda Center minutes file that records the unanimous vote is labeled Sept. 3, 2026. Both are attributed in the article.
