What can a building or property be used for?
Permitted uses differ depending on a property's zoning. Reference the Zoning Ordinance Land Use Table for a list of zoning districts, which are are listed across the top of the table and uses are listed in the left column.

Uses are either prohibited, permitted by right, or conditional. If the use is prohibited, the space will be blank. If the use is permitted by right, an "X" will appear in the space. If the use is conditional, a "C" will appear in the box. The Board of Zoning Appeals must approve conditional uses.

E-mail planning staff at planning@ci.collierville.tn.us if you do not know the zoning of the property.)

Can the Board of Zoning Appeals grant a variance to allow a use that is not permitted in a particular district?
No. The Zoning Ordinance prohibits the Board of Zoning Appeals from granting use variances.

How long does a Conditional Use Permit last?
Conditional uses (along with all approved plans, conditions, restrictions, and requirements) "run with the land," unless the Board of Zoning Appeals stipulates an expiration date as part of the approval. ("Run with the land" means that the approval would not be denied once the property owner changes. The approval will pass on to subsequent property owners.)

Can a Conditional Use Permit expire?
Yes. Failure to begin construction of the conditional use within one year of the approval by the Board of Zoning Appeals or failure to fully establish the conditional use within 2 years of the approval by the Board of Zoning Appeals, results in voiding the conditional use permit. (Begin construction usually means having received a grading permit and begun
grading.)

What is a Non-conforming Use?
A use of a building, structure, or land that does not conform to the uses approved in the current Zoning Ordinance, but that is a lawful use because it was undertaken before the current Ordinance was adopted. The same non-conforming use may continue with change of ownership, only if the same non-conforming use is re-established within one year. Only incidental alterations are permitted to a non-conforming use. A structure used for a non-conforming use cannot be rebuilt if damage exceeds 50% of the replacement cost. A non-conforming use cannot be changed to another non-conforming use.

What is a Non-complying Structure?
A building or structure that does not comply with bulk regulations (setbacks, height, lot coverage) in the current Ordinance, but that is lawful because it existed before the Ordinance was adopted. A non-complying building or structure can be enlarged, as long as the enlargement does not create a new non-compliance or increase the degree of noncompliance. Once involuntary damage is incurred to 50% of the building's floor area, that non-complying building or structure must be reconstructed to meet the currently adopted bulk regulations. (The Board of Zoning Appeals may permit the damage to be calculated by cost instead of floor area.)

Calculations:

How to Measure the Height of a Building
Measure the distance from the ground to the midpoint between the eave and ridge. Exclude uninhabitable church spires, belfries, cupolas, domes, and chimneys.

How to Measure Fence Height
Measure from the finished surface of the top of the fence to the finished grade.

How to Calculate Floor Area Ratio
Divide the building's total square footage by the lot's total square footage. For example, for a building containing 3,000 square feet on a lot that is 12,000 square feet in size, divide 3,000 by 12,000 for a FAR of 0.25.

How to Calculate Gross Floor Area
Add the horizontal areas of all the floors (measuring from the exterior face of the exterior walls or the center of party walls), excluding off-street parking spaces, loading berths, and driveways. For non-residential properties, also exclude arcades, porticoes, and other similar open areas not used for sales, display, storage, service, or production.

How to Calculate Net Floor Area
The net floor area equals the gross floor area minus vents, shafts, courts, elevators, stairways, and other similar facilities.

How to Calculate Lot Coverage
Add the portion of the lot that is covered by the principal building and accessory structures (does not include parking lot).

How to Calculate Open Space Ratio
Calculate the total square footage of green open space, that portion of a lot that is open from the ground to the sky and not covered by buildings or impervious surfaces, such as parking lots and driveways, and divide that total square footage of green open space by the total square footage of the lot.


Signs
Where to Obtain a Sign Permit

At the Development Division offices at Town Hall, 500 Poplar View Parkway

How to Calculate the Area of a Sign
Measure the smallest rectangle or square that will encompass the extreme limits of the writing, emblem, or other display, together with any material or color forming an integral part of the background used to differentiate the sign from the backdrop. Do not include supporting framework, bracing, or decorative wall.

How to Measure the Height of a Sign
Measure from the base of the sign at normal grade to the top of the highest attached component of the sign.

How many signs can a business have?
In office, commercial, and industrial zoned districts, each ground floor business is permitted 2 business signs (any combination of wall signs, ground signs, or permanent window signs) facing each street the business fronts. The combined area of these signs cannot exceed 1½ square feet of signage for every 1 foot of building frontage, to a maximum of 150 square feet of signage, unless additional square footage is approved by the Board of Zoning Appeals.

In office, commercial, and industrial zoned districts, each second or third floor business that has an exterior entrance is permitted 1 wall sign that is not to exceed 4 square feet in size and that is to be located adjacent to the entrance.

Required Height of a Ground Sign Structure (base)
24 inches

Prohibited Signs
pole signs; roof signs; animated, reflective, or flashing signs; strings of lights or beacon lights; obscene signs; signs that read "stop" or that can be confused for traffic signs; signs with 2 faces further that 12 inches apart; billboards; signs attached to vehicles or trailers parked in public place or visible from street; manual or electric changeable copy signs (except for civic, institutional, or schools); and backlit canopies. For more information, see the Sign Ordinance provisions included in the Collierville Zoning Ordinance.

Exempt Signs
flags or emblems of the United States, Tennessee, or their political subdivisions; government regulatory, control, or traffic signs; memorial or historical plaques; door bell or mailbox signs 36 square inches in size or less; 1 ½ square feet in size, non-illuminated instructional signs; election signs; hand carried signs; works of art with no commercial message; signs in the Historic District as approved by the Historic District Commission; holiday lighting between Thanksgiving day and New Year's day and 15 days prior and after those days; signs affixed to vehicles in transport; and BMA approved temporary street banners. For more information, see the Sign Ordinance provisions include imn the Collierville Zoning Ordinance.

Setbacks
How to Measure the Setback Line

Measure the distance between the street line and the closest portion of the principal building, including covered porches and roof overhangs. The street line is the property line that bounds the right-of-way (which is set aside for the street). If there is a sidewalk, the street line is the side of the sidewalk furthermost from the street. (Especially for older subdivision, verify the setbacks on the recorded plat in the Town Engineering Division.)

What is the Minimum Required Setback?
Minimum required setbacks differ depending on the property's zoning. (Email planning staff at planning@ci.collierville.tn.us if you do not know the zoning of the property.)

If the property is located in a Planned Unit Development, the setbacks may be different than that of the underlying zoning, so verify the setbacks with planning staff.

How to Determine Setbacks for Corner Lots
Corner lots have two front yards, a side, and a rear. Minimum front yard setbacks requirements must be maintained on both yards with street frontage. The rear yard is located opposite the direction in which the house faces.

Accessory Structures

What is an Accessory Structure?
A structure that is located on the same lot as the principal building, detached from the principal building, and that has a use that is incidental to the principal building. Examples include a detached garage, workshop, pool house, and swimming pool.

Where can an accessory structure be located?
Accessory structures may be located in the rear yard.
Accessory structures cannot be located in a front yard.
Accessory structures cannot be located in the required side yard unless the parcel is a corner lot.

Required yards are determined by the minimum required setback. For example, if the minimum side yard setback is 15 feet and the principal building is setback 40 feet, an accessory structure could be located in the side yard, as long as it did not encroach into that required 15 feet.

Temporary Structures

What uses are permitted in temporary structures?
Construction - permitted by right on commercial development sites zoned commercial, industrial, or medical/professional/office; requires permit from Construction Codes

Storage - not permitted in residential zone districts; conditional use in non-residential zone districts upon approval of the Board of Zoning Appeals

Other non-prohibited uses - conditional use upon approval of the Board of Zoning Appeals

What uses are specifically prohibited in temporary structures?
sales, leasing, and hiring

Fences

When to Obtain a Fence Permit
Before beginning installation of a new fence, relocating an existing fence, or reconstructing 50% or more of an existing fence.

Where to Obtain a Fence Permit
Fence permits may be obtained from the Code Compliance Division at Town Hall. Enter Town Hall from the eastern estrance. Town Hall is located at 500 Poplar View Parkway. Code Compliance staff is available from 7:00 AM to 4:00 PM during regular business.

What is the Maximum Fence Height?
Maximum Height for Front Yards: 48 inches
Maximum Height for Side and Rear Yards: 6 feet

Measure fence height from the finished surface of the top of the fence to the finished grade.

Permitted Fence Materials
wood, brick, vinyl, ornamental iron, ornamental aluminum, or other materials approved by the Design Review Commission or Historic District Commission

Prohibited Fence Materials
chain link, vinyl coated chain link, wire mesh, single wire, electrified, cinder block, concrete block, barbed wire

The Design Review Commission may approve chain link for legally approved animal boarding, health care, or sports facilities or the side and rear yards of industrial zoned properties. The Design Review Commission may approve single wire or electrified fencing for active livestock and farming operations.

Where can fences be located?
Front Yards on Interior Lots: Fences exceeding 48" in height shall not extend beyond the front face of the principal building

Front Yards on Corner Lots in which House Faces Street: Fences exceeding 48" in height shall not extend beyond the front face of the principal building or the front yard setback line, whichever distance from the property line is greater.

Front Yards on Corner Lots in which House does not Face Street: Fences not exceeding 6 feet in height may be located no more than 10 feet into the front yard setback. Fences not exceeding 48" in height may be located 20 feet from the back edge of the curb.

Side and Rear Yards: Fences may be located on the lot line in side and rear yards (unless prohibited on the final subdivision plat or site plan).

In or along easements: Fences installed in easements are subject to removal at the owner's expense if maintenance or construction is required.

Around pools: A minimum 48" tall fence is required around swimming pools.

 

Parking

How many off-street parking spaces are required for Commercial activities?
The maximum number of permitted parking spaces is based upon a ratio of 1 parking space per 200 square feet of gross building area, but in no case shall the number of spaces be less than four. The minimum required number of parking spaces can be found in the "Table of Off-Street Parking Requirements." included in the Collierville Zoning Ordinance.

What is the minimum required size of an off-street parking space?
Standard: 9' wide X 20' long
Handicap: 14' wide X 20' long

Boards and Commissions

When is Planning Commission approval required?
The Planning Commission (and Board of Mayor and Aldermen) must approve the Site Plan for all new buildings and additions, all non-residential manufactured buildings or pre-fabricated buildings; and site alterations including the construction or expansion of driveways, parking areas, and loading areas. This does not apply to single-family detached dwellings and their accessory structures.

When is Design Review Commission approval required?
Non-Residential: The Design Review Commission (DRC) must approver the Site Plan for all new buildings and additions, all manufactured or pre-fabricated buildings; and site alterations including the construction of driveways, parking areas, and loading areas. The DRC must also approve exterior alterations of buildings or accessory structures, and site alterations including parking, landscaping, lighting, fencing, and signage (excludes single-family detached residential dwellings).

Residential: The DRC must approve fencing, landscaping, lighting, buffering/screening of subdivisions and multi-family residential developments. DRC approval is also required for front yard fences that exceed 48" in height on single-family detached residential properties.

When is Historic District Commission approval required?
The Historic District Commission must approve new construction, additions, building or site alterations, demolition, relocation, signage, fencing, on all properties located within the local historic district.

Where are board and commission meetings held?
Board and Commisison meetings are typically held at Town Hall Board Chambers at 500 Poplar View Parkway. Contact the Planning Division at 457-2360 to confirm meeting dates and locations.

What is the Board Approval Process?
Before the Division of Construction Code Enforcement can review plans and issue building permits for new construction and site alterations for non-single family residential dwellings, the following boards and commissions within the Planning Division must review and approve the proposed construction.

1. Planning Commission
2. Design Review Commission
3. Board of Mayor and Alderman

If the property (residential or non-residential) is located in the Historic District, the Historic District Commission must also review the application, usually first.

If a Variance or Conditional Use Permit is necessary, Board of Zoning Appeals approval is also required, typically prior to the Planning Commission.
