Build Guide: Shawnee, Kansas
Shawnee, Kansas is a city of roughly 70,000 residents spread across about 42 square miles of Johnson County, running west from the Merriam and Overland Park line out past K-7. Two things are worth clearing up locally: Shawnee is not Shawnee Mission, which is a postal designation the Post Office created in 1960 covering sixteen northeast Johnson County cities and is also the name of a school district, and it is not Shawnee, Oklahoma.
Faust Construction builds new homes, additions, and whole-house renovations in Shawnee and across the Kansas and Missouri sides of the Kansas City metro.
What defines Shawnee
Shawnee is the largest city by land area in this part of Johnson County and one of the most varied. A Shawnee Indian mission was established on the site in 1831, the town was laid out in 1857, and Quantrill burned it to the ground in October 1862. What grew back was a small town that spent the twentieth century becoming a suburb, and then kept going west.
Today the city is effectively two markets. The older eastern half around the Nieman corridor and downtown carries mid-century and postwar housing on modest lots, in the Shawnee Mission school district. West of K-7, in the De Soto district, the lots are larger and newer, and that is where nearly all of Shawnee’s current residential development is happening: Harmony at Clear Creek near Silverheel and K-7, Cedar Trace at Silverheel and Monticello, Hidden Creek Reserve near Chapel Creek.
For a custom home, that split is the first question. An east-side project is almost always a renovation, addition, or teardown rebuild on an established block. A west-side project is more likely to be new construction on a larger lot with meaningful grade.
What homeowners should know
Shawnee is the metro city most likely to surprise a builder with its submittal requirements rather than its design rules. The requirements below come from the city’s Building Permits and Inspections page and its published Single Family Residence Permit Guidelines.
Shawnee requires sealed plans for an ordinary house
This is the difference that catches people. Shawnee states that plans prepared by a design professional are required for all buildings, including single-family and two-family residential structures, and that a registered design professional licensed in the State of Kansas must seal each page. On top of that, the pre-construction stake plot plan must be sealed by a Kansas registered land surveyor.
Several neighboring Johnson County cities will accept unsealed residential plans. Shawnee will not. If a design is being carried over from a project in another city, that is a cost and schedule item to settle at the front, not at submittal.
Plan format is specified too: minimum sheet size of 18 by 24 inches for a single-family detached house, floor plans at no less than quarter-inch scale, elevations at no less than eighth-inch scale, plus an electronic set.
Shawnee split its code adoption, and wrote its own security amendment
As of April 1, 2026 Shawnee enforces the 2024 International Building, Fire, Plumbing, Mechanical, and Fuel Gas Codes and the 2023 National Electrical Code, but holds residential construction at the 2018 International Residential Code and the 2018 International Energy Conservation Code.
Shawnee has also amended the 2018 IRC by adding Section R328 Physical Security, establishing minimum standards intended to make dwelling units resistant to unlawful entry. That section is a Shawnee invention. It does not exist in the model code and it does not apply in any neighboring city, so it has to be designed for rather than discovered at inspection.
Setbacks and lot standards by district
Shawnee’s residential districts run from R-1 Single Family through RS Suburban and RE Estates, along with AG, CE Country Estates, PSF, PSF-AR, DU, RGA, and RHR. Zoning is Title 17 of the municipal code and subdivisions are Title 16. The three districts most single-family projects fall under are in the table below.
Note that the numbers in that table come from the city’s own permit guideline documents rather than from the ordinance text, which sits on a code platform we could not read directly. For a specific lot, confirm against Title 17 with the Building Codes Division at (913) 742-6010.
Erosion control kicks in at 1,000 square feet of roof
A site-specific Erosion and Sediment Control Plan is required for construction of a new roofed structure with a projected roof area of more than 1,000 square feet where the cumulative land disturbance is under an acre. All control measures, including a gravel construction entrance, must be in place before any land disturbance begins.
Grades are specified as well: impervious surfaces at a minimum gradient of an eighth of an inch per foot, driveways between one and fifteen percent, and a maximum algebraic difference in grades at the right of way line of eight percent for crest drives and twelve percent for sag drives. Whether stormwater detention is required is decided case by case by the Development Engineering Manager rather than by a published threshold.
Street trees are required on new development
Street trees are optional in existing residential subdivisions but required for any new residential development, at one tree per 40 feet of public or private street frontage plus one additional tree per dwelling unit, from the city’s approved species list. Landscape plans must show any tree of 12 inch caliper or larger proposed for removal.
Demolition
A demolition permit is 60 dollars and requires verification of all utility kills, a KDHE asbestos demolition notification with a copy of the KDHE letter of receipt, and written permission from the owner. The method of demolition must be stated on the application and explosives are not permitted. Foundations must be removed completely unless a building permit application has been made for the rebuild. No neighbor notification requirement appears in the city’s published demolition guidelines.
Permits expire, and contractors need two credentials
A Shawnee permit expires if work is not started within six months or if no inspection is obtained in any six-month period, and it expires outright two years after issuance. Plan review is charged at 65 percent of the permit fee, and revisions are billed at 50 dollars per hour with a two-hour minimum.
On licensing, Shawnee requires both. A contractor must hold a valid Johnson County Class A, B, or C contractor license and a valid City of Shawnee business license. Crossing a city line into Shawnee is not automatic, and that catches out-of-city subs regularly.
| Standard | R-1 Single Family | RS Suburban | RE Estates |
|---|---|---|---|
| Minimum lot area | 9,000 sq. ft. | 12,000 sq. ft. | 1 to 2 acres |
| Minimum frontage | 75 ft. | 90 ft. | 160 ft. |
| Front setback | 30 ft. | 35 ft. | 50 ft. |
| Side setback | 20% of lot width, 7 ft. min. | 15 ft. | 25 ft. |
| Rear setback | 30 to 40 ft. | 35 to 40 ft. | 40 to 50 ft. |
| Maximum height | 45 ft. / 3 stories | Confirm with the city | Confirm with the city |
Why Shawnee projects take local experience
Faust Construction has built in the Kansas City metro for more than 25 years. Shawnee is a city where the submittal package, not the design review, is what decides whether a project starts on time. Sealed architectural plans, a surveyor-sealed stake plot plan, an erosion control plan triggered at 1,000 square feet of roof, and a city business license on top of the county contractor license all have to be in hand before anything is issued.
Our pre-construction phase assembles that package. We work as consultants alongside the architect and homeowner before construction starts, pricing the design against the 2018 residential code Shawnee still enforces including its own R328 security amendment, and building a schedule around a permit that expires in two years and lapses after any six months without an inspection.
Pre-construction
We price the design, evaluate materials and alternatives, and build a schedule that accounts for city review milestones.
Construction
We work with a consistent group of craftsmen and trade partners, with daily on-site presence throughout the build.
Management
We track cost against budget transparently and meet monthly with the architect and homeowner.
What we build in Shawnee
Shawnee spans postwar blocks in the east and large newer lots west of K-7, and the work follows that range.
- New construction. New homes on the larger west-side lots, drawn and sealed by a Kansas registered design professional and staked by a Kansas registered land surveyor as the city requires.
- Additions. Kitchen, primary suite, and living space expansions on established east-side lots, with erosion control required once the new roof area passes 1,000 square feet.
- Whole-house renovations. Reworking layout, systems, and finishes in mid-century and postwar houses in the Nieman corridor and downtown neighborhoods.
- Interior renovations. Kitchens, baths, and basement finishes, where structural changes still require a permit and a sealed plan set.
Our completed work spans new construction, additions, and full renovations across the Kansas City metro. Shawnee sits inside our regular service area alongside Mission Hills, Fairway, Westwood, Prairie Village, Leawood, Overland Park, and the Kansas City, Missouri neighborhoods along Ward Parkway.

Questions about building here
Answers to what homeowners ask before starting a project in this area.
Is Shawnee, Kansas the same as Shawnee Mission?
No. Shawnee is an incorporated city of roughly 70,000 people in Johnson County, Kansas. Shawnee Mission is not a city at all: it is a postal coverage area the Post Office created in 1960 spanning sixteen northeast Johnson County municipalities, and it is also the name of a school district. Mail addressed either way reaches the same place, but the city that issues your building permit is Shawnee. This is also not Shawnee, Oklahoma.
Does Shawnee, Kansas require sealed plans for a house?
Yes, and this is the requirement that catches builders coming from neighboring cities. Shawnee states that plans prepared by a design professional are required for all buildings, including single-family and two-family residential structures, and that a registered design professional licensed in the State of Kansas must seal each page. The pre-construction stake plot plan must additionally be sealed by a Kansas registered land surveyor. Several nearby Johnson County cities accept unsealed residential plans; Shawnee does not.
What building code does Shawnee, Kansas enforce?
As of April 1, 2026 Shawnee enforces the 2024 International Building, Fire, Plumbing, Mechanical, and Fuel Gas Codes and the 2023 National Electrical Code, but holds residential construction at the 2018 International Residential Code and the 2018 International Energy Conservation Code. Shawnee has also amended the 2018 IRC with its own Section R328 Physical Security, setting minimum standards to make dwellings resistant to unlawful entry. R328 does not exist in the model code and does not apply in neighboring cities.
What are the setbacks for a house in Shawnee, Kansas?
They depend on the district. R-1 Single Family requires a 30 foot front setback, side setbacks of 20 percent of lot width with a 7 foot minimum, and a 30 to 40 foot rear setback on a minimum 9,000 square foot lot with 75 feet of frontage, at a maximum height of 45 feet or three stories. RS Suburban requires 35 foot front, 15 foot side, and 35 to 40 foot rear on 12,000 square feet. RE Estates requires 50 foot front, 25 foot side, and 40 to 50 foot rear on one to two acres. These come from the city’s permit guideline documents; confirm against Title 17 for a specific lot.
How long is a Shawnee, Kansas building permit valid?
A Shawnee permit expires if work is not started within six months, or if no inspection is obtained in any six-month period, and it expires outright two years after the date it is issued. Plan review is charged at 65 percent of the permit fee, and plan revisions are billed at 50 dollars per hour with a two-hour minimum.
Do contractors need a Shawnee license as well as a Johnson County one?
Yes, both. A contractor working in Shawnee must hold a valid Johnson County Class A, B, or C contractor license and a valid City of Shawnee business license. Shawnee does not run its own contractor licensing program, but the business license is separate and is required for every contractor working in the city, which regularly catches subcontractors crossing in from other Johnson County cities.
