Two Lines Around Collierville's Square Decide Whether Your Window Replacement Needs the Town's Approval

In November 2024, the Town of Collierville's Historic District Commission agenda recorded that a property owner named Jeb Blanchard applied to replace the windows on his building at 218 E. Poplar Avenue. The project was a window replacement, with no addition or demolition involved. The application still required a full Certificate of Appropriateness review by the town's Historic District Commission, complete with a vicinity map, historic survey references dating to 2004, cutsheets for the proposed windows, and a copy of the permit itself, all filed ahead of the commission's November 19 meeting.

A full commission review for a window swap can surprise an owner until they see what triggers it. The address sits inside Collierville's Local Historic District Overlay, a boundary the town drew around its Square that has real regulatory teeth. A few blocks away, a home can carry the same "historic" reputation, even sit inside the National Register Historic District, and face none of that review for the exact same project. The two designations get talked about as if they're one thing. They aren't. Knowing which one applies to a specific address can affect your renovation timeline before you've poured a single foundation.

One Property, Two Different Lines

Collierville's Town Square carries two separate historic boundaries that don't perfectly overlap. Memphis Heritage Inc., the regional preservation nonprofit, describes the local designation as the Local Historic District Boundary and the federal one as the National Register Historic District Boundary, and notes on its own map of the area that the two lines are drawn differently, one solid and one dashed, because they don't trace the same footprint.

The National Register listing is an honor. It does not, by itself, give the Town of Collierville any authority over what you do to your house. The Local Historic District Overlay, often shorthand as H-1, is the one that matters at the permit counter under the Town of Collierville's current zoning code. Properties inside that overlay fall under the jurisdiction of the town's Historic District Commission, a seven-member board whose stated duty is to preserve historic and architectural value and to weigh in on any alteration, addition, demolition, or exterior change visible from the public right of way, then approve or deny a Certificate of Appropriateness case by case.

The commission meets once a month, usually on the fourth Thursday at 4:00 p.m. in Town Hall.

The Overlay Isn't Rare, It's Routine

This isn't a hypothetical rule that only shows up once in a while. The Town of Collierville's own historic preservation program page states that the Historic District Commission has issued Certificates of Appropriateness for more than 300 private properties inside the H-1 Overlay. That's not an edge case. That's the ordinary cost of owning inside the line.

The Blanchard window case at 218 E. Poplar Avenue is what that looks like in practice for an owner who isn't trying to demolish anything or build up. The paperwork trail for that single case included a historic survey from 2004 and design guideline citations, the same documentation weight you'd expect for something far larger.

The Six-Year Version of the Same Rule

If a window replacement shows the rule at its smallest scale, the former Gus's Fried Chicken building at 215 S. Center Street shows what happens when the same rule meets a much bigger project.

The restaurant operated there from 2008 to 2022, then sat vacant. A Town of Collierville meeting recording shows that, in December 2019, the Historic District Commission denied a Certificate of Appropriateness for its demolition, finding the structure still carried historical significance. The building stayed standing for years after the denial. In August 2025, the commission conditionally granted a Certificate of Economic Hardship, clearing the way to finally take the building down.

By January 22, 2026, the property was back in front of the commission, with McCarty Grandberry Engineering as the applicant, and a preliminary site plan for a three-story mixed-use replacement: roughly 6,747 square feet of ground-floor retail and office space with 12 residential units above it, designed to match the architecture of the existing buildings around the Square. Town planning staff noted at that meeting that the parcel sits within the Local Historic Overlay but outside the National Register district, the same split boundary at work again, just on a corner lot instead of a single-family home. Even with a staff recommendation of approval, the project still had to clear a Planning Commission meeting and a vote by the Board of Mayor and Aldermen before permits could be pulled.

Total elapsed time from the first denied demolition request to a workable path forward: more than six years. Most buyers and sellers won't face anything close to that timeline. But the mechanism that produced it, an overlay board with monthly meetings and a case-by-case standard for what counts as appropriate, is the same one that reviewed a set of replacement windows on Poplar Avenue.

Comparing Market Figures

Listings tagged historic district in Collierville have carried a median list price of $558,000 in a recent market snapshot, notably higher than the town's broader median sale price, which has been running near $483,000 through 2026. The figures compare a median list price for tagged listings with the town's broader median sale price; they do not establish what accounts for the difference.

For a seller, the practical question isn't whether the overlay makes a home harder to sell. Buyers who want proximity to the Square generally know what they're getting into. A buyer's attorney or agent asking about HDC history on a specific parcel is asking a reasonable question, not a suspicious one.

For a buyer planning any exterior work, from a new roof to a full addition, the timeline math changes the moment the parcel sits inside H-1. A demolition request that the commission views as removing historical fabric can add years, as the Gus's building shows in the most literal way it fields.

Before You Write an Offer or Sign a Listing Agreement

A few checks are worth doing before either side of a transaction near the Square goes further:

• Confirm which boundary the parcel actually sits inside. The Town's Planning Division maintains the zoning map showing the H-1 Overlay separately from the National Register lines, and the two don't always match.
• Ask whether any planned exterior work, including something as ordinary as windows or siding, will need a Certificate of Appropriateness before a building permit can be pulled.
• Build the commission's meeting schedule into your renovation timeline: it usually meets on the fourth Thursday each month.
• If a project involves any demolition, budget time and documentation for a possible Certificate of Economic Hardship request rather than assuming approval is automatic.
• Ask the seller or listing agent whether any HDC case history, open or closed, is tied to the specific address.

A Few Questions Worth Settling Before You Close

Does National Register listing alone stop me from replacing my windows? No. National Register status recognizes a property's historical value, but it doesn't give the town review authority over your renovation. Only sitting inside the Local Historic District Overlay triggers the Certificate of Appropriateness requirement.

How do I find out which boundary my address falls inside? Contact Collierville's Planning Division directly. Its zoning map shows the H-1 Overlay boundary as a distinct layer from the National Register boundary, and staff can confirm which one, or both, applies to a specific parcel.

What work does the commission review? Based on the commission's stated scope, review covers alterations, additions, demolition, and exterior changes visible from the public right of way.

If you're weighing a purchase near Collierville's Square, or thinking about listing a home that sits inside that overlay, it's worth knowing which line your address falls on before you plan a renovation or set a closing date around it.
