Site Plan for Permit in Knoxville, TN: Site Plans for Home Projects
Planning a home addition, garage, deck, porch, shed, pool or other residential project in Knoxville? A clear site plan helps reviewers understand where the proposed work will be located and how it relates to the complete property.
The drawing can show property boundaries, existing buildings, proposed construction, setback dimensions, driveways, easements, utilities, grading, drainage and other conditions relevant to building and zoning review.
Quick answer
A Knoxville residential site plan is a scaled overhead drawing showing the complete lot, existing structures, proposed project and relevant distances to the property lines. The information required depends on the project, zoning district, land disturbance and property-specific conditions.
Confirm whether the property is inside Knoxville city limits
A Knoxville mailing address does not always mean the property is regulated by the City of Knoxville. Some addresses are located in unincorporated Knox County. Confirm the reviewing jurisdiction before using city permit instructions or zoning requirements.
What Is a Residential Site Plan?
A residential site plan is a scaled, top-down drawing of a parcel of land. It shows where buildings and exterior improvements are positioned in relation to the property boundaries.
A floor plan explains what is happening inside a house. A site plan explains how the house and proposed project fit on the property.
The drawing can help permit reviewers understand:
- The complete size and shape of the lot
- The location of the existing residence
- The size and position of the proposed construction
- The distance from the project to each property line
- The separation between existing and proposed structures
- How vehicles and pedestrians access the property
- Whether easements, utilities, slopes or drainage may be affected

Everything You Need to Know About a Site Plan
.
Knoxville Home Projects That May Need a Site Plan
A site plan is commonly requested when residential work changes the building footprint, exterior property layout, parking or access.
Bedrooms, kitchens, family rooms, mudrooms and other extensions that enlarge the existing residence.
New homes requiring coordinated site, architectural, structural and utility information.
Attached or detached vehicle structures that affect setbacks, driveway access and lot coverage.
Outdoor structures involving footprints, stairs, landings, setbacks and connections to the house.
Storage buildings, workshops, greenhouses and other structures proposed in a side or rear yard.
Pools, decks, equipment, barriers, gates and distances to buildings and property boundaries.
New or modified access, parking areas, curb connections and paved surfaces.
Projects involving excavation, fill, slopes, drainage or changes to existing ground levels.
A minor interior renovation may not require the same site information. The required documents depend on the project scope and the approvals applying to the property.
What Should a Knoxville Site Plan Show?
The precise information depends on the property and project, but a useful residential permit site plan commonly includes the following elements.
| Site-plan element | What the drawing should communicate |
|---|---|
| Property boundaries | The complete parcel outline and available boundary dimensions. |
| Existing residence | The house footprint and its position within the lot. |
| Existing improvements | Garages, carports, sheds, decks, porches, pools, driveways and retaining walls. |
| Proposed construction | A clearly labeled footprint showing the proposed location, length and width. |
| Setback dimensions | The shortest distances from the project to the front, side and rear property lines. |
| Building separation | Distances between the proposed work and existing structures where relevant. |
| Street and access | Street names, driveway, curb access, sidewalks, gates and pedestrian routes. |
| Easements and utilities | Known drainage, utility, sewer, access and other recorded restrictions. |
| Grading and drainage | Slopes, retaining walls, surface-flow direction and elevations when required. |
| Drawing information | Property address, parcel information, north arrow, scale, labels and revision date. |
Knoxville Zoning and Property Setbacks
Knoxville’s Zoning Code controls what land and buildings may be used for, where structures may be located and how large they may be.
The code also addresses site-development elements such as:
- Accessory structures
- Parking
- Landscaping
- Lot coverage
- Building height
- Yard requirements
- Overlay districts
Residential properties may be located in districts such as:
- EN Established Residential Neighborhood
- RN-1 Single-Family Residential Neighborhood
- RN-2 Single-Family Residential Neighborhood
- RN-3 through RN-7 General or Multi-Family Residential Neighborhood districts
The correct setback depends on the property’s zoning district, structure type and site conditions. Do not copy the setbacks used for another house without checking the zoning requirements for the individual parcel.
Official zoning resources:
Knoxville-Knox County Planning Zoning and Regulations
and
City of Knoxville Zoning Code User’s Manual
.
Setbacks should be dimensioned clearly
The site plan should show the actual shortest distance between the proposed project and each relevant lot line.
Depending on the project, show:
- Front-yard distance
- Both side-yard distances
- Rear-yard distance
- Distance between the project and the existing house
- Distance from roof overhangs, stairs or other projections
- Distance to easements or restricted areas
Do not rely only on the fence
An existing fence, hedge, driveway edge or retaining wall may not be located on the legal property boundary. Use reliable property records and obtain a licensed survey where exact boundary verification is required.
Unsigned Site Plan Versus Licensed Survey
USA Site Plans prepares unsigned residential drawings using property records and project information supplied by the customer.
An unsigned drafted plan can organize:
- Property boundaries shown on supplied records
- Existing buildings
- Proposed project dimensions
- Setback measurements supplied by the customer
- Driveways, paving and other site features
It does not independently establish or certify legal boundaries.
A Tennessee licensed land surveyor may be needed when:
- The proposed work is close to a property line
- Property corners cannot be located
- The lot is narrow or irregular
- The existing fence appears out of alignment
- A neighbor disputes the boundary
- Available records conflict
- The city requests professionally verified information
Important service distinction
An unsigned site plan should not be represented as a certified survey, architectural drawing or engineered site-development plan. Confirm the required professional credentials before ordering or submitting documents.
Current Knoxville Residential Building Codes
The City of Knoxville has adopted the 2024 International Residential Code for qualifying single-family houses, duplexes and townhouses.
The city’s adopted construction codes also include:
Building and residential
The 2024 International Building Code, 2024 International Residential Code and 2024 International Existing Building Code.
Mechanical and plumbing
The applicable 2024 mechanical, plumbing and fuel-gas codes with local amendments.
Electrical and energy
The adopted 2023 National Electrical Code and 2018 energy-conservation provisions.
A site plan does not replace the construction drawings needed to demonstrate compliance with these codes.
Official resource:
City of Knoxville Construction Codes
.
Other Drawings a Home Project May Need
The site plan explains the project’s location. A complete permit application may also require construction details.
Depending on the project, supporting documents may include:
- Floor plans
- Exterior elevations
- Building sections
- Foundation or footing plans
- Structural framing drawings
- Deck framing and connection details
- Stair, handrail and guard information
- Mechanical plans
- Plumbing plans
- Electrical plans
- Energy-code documentation
- Manufacturer specifications
- Structural calculations
- Engineered grading or drainage plans
The site plan should match the other documents. If a floor plan shows a 12-foot by 20-foot addition, the site plan should not show a different footprint.
Land Disturbance, Grading and Drainage
Home projects can affect the land even when the proposed building is relatively small.
City Engineering states that work disturbing or changing land requires a site-development permit. The exact submission requirements depend on the amount of disturbance and the project.
Projects that may involve additional site review include:
- New houses
- Large additions
- New driveways
- Swimming pools
- Retaining walls
- Projects involving excavation or fill
- Work on steep or sloping property
- Projects changing existing drainage patterns
The site or supporting engineering plans may need to show:
- Existing and proposed contours
- Spot elevations
- Finished-floor elevation
- Areas of excavation and fill
- Retaining walls
- Surface-water direction
- Drainage swales
- Stormwater structures
- Erosion and sediment controls
- Limits of disturbance
Official resource:
City of Knoxville Engineering Plans Review
.
A standard drafted site plan can display grading and drainage information supplied by the customer or project professional. It does not provide engineered stormwater calculations or certify site elevations.
Driveways and the Public Right-of-Way
A residential site plan should clearly show how vehicles and pedestrians reach the property.
Relevant features may include:
- Adjacent street name
- Existing driveway
- Proposed driveway or widening
- Driveway width
- Garage or carport entrance
- Parking area
- Sidewalk
- Curb or edge of pavement
- Vehicle gate
- Nearby drainage structures
A separate permit may be required when construction, excavation or utility work extends into the public right-of-way.
Official resource:
City of Knoxville Civil Engineering Permits
.
Easements and Utilities
Easements can limit where permanent structures, foundations, slabs and retaining walls may be placed.
Common restrictions include:
- Drainage easements
- Utility easements
- Sewer easements
- Access easements
- Shared-driveway easements
- Water-line easements
Depending on the project, supplied utility information may identify:
- Water service
- Sewer service
- Gas service
- Electrical service
- Utility meters
- Overhead utility lines
- Stormwater connections
A drafted site plan does not locate underground utilities independently. Use utility records and qualified locating services where required.
Historic and Overlay Districts
Knoxville has several overlay districts that can affect residential development, including historic, neighborhood-conservation, infill-housing, hillside-protection and floodplain overlays.
Construction or demolition within a designated local historic zone is reviewed by the Historic Zoning Commission.
Projects that may receive historic review include:
- Home additions
- Decks and porches
- Detached garages
- Accessory buildings
- Exterior alterations
- New construction
- Demolition or relocation
A site plan can help show:
- The relationship between the proposed work and existing house
- Visibility from the street
- Existing accessory buildings
- Driveway and parking location
- Property boundaries
- Existing and proposed footprints

Frequently Asked Questions
Does every Knoxville home project need a site plan?
No. The required documents depend on the work. Projects that create or enlarge a building footprint, add an accessory structure, install a pool, modify access or affect setbacks are more likely to require a site plan.
Is a Knoxville mailing address always inside the city?
No. Some properties with Knoxville mailing addresses are located outside city limits and are reviewed under Knox County requirements. Confirm jurisdiction before preparing the application.
Can an unsigned plan certify my legal property boundary?
No. An unsigned drafted plan can show boundaries based on supplied records, but it does not establish or certify the legal property line. A Tennessee licensed land surveyor may be required.
Does Knoxville use the 2024 Residential Code?
Yes. The City of Knoxville’s current construction-code page identifies the 2024 International Residential Code among its adopted codes.
Does a deck require construction drawings?
A deck permit package may require a dimensioned plan, footing information, framing, connections, stairs, guards and other construction details. The site plan only shows where the deck is positioned on the property.
Does a site plan include structural engineering?
No. A site plan shows the project’s location. Foundations, beams, framing, footings, retaining-wall design and structural calculations are separate documents.
What if the project changes the grading?
Additional site-development, grading, drainage or erosion-control information may be required. Confirm the applicable Engineering requirements before construction.
What if the house is in a historic district?
Construction or demolition within a designated historic zone may require Historic Zoning Commission review before the building permit can proceed.
How quickly can USA Site Plans prepare the drawing?
USA Site Plans offers a standard 24-hour turnaround for typical unsigned residential drafting orders when sufficient property records, dimensions and project information are supplied.
Does an unsigned site plan guarantee permit approval?
No. Approval depends on the property, project, zoning, building code and review by the responsible authorities.

Final Thoughts
A clear Knoxville residential site plan should make the property and proposed home project easy to understand.
The drawing should show property boundaries, existing buildings, proposed construction, setback measurements, driveway access and other relevant site conditions.
Depending on the property and project, the permit process may also involve zoning review, historic approval, land-disturbance requirements, grading, drainage or professionally prepared plans.
Confirm the jurisdiction first, because properties within the City of Knoxville and unincorporated Knox County follow different zoning and permitting requirements.
