Where do I pull a permit for a Stilwell hardscape project?

Stilwell is unincorporated Johnson County, Kansas, so there is no city building department. Permits run through the Johnson County Building Codes Division (Department of Planning, Housing and Community Development). The phone line is 913-715-2200 Option 1, and email is planningandcodes@jocogov.org. Residential permits typically take 7 to 10 business days from a complete submittal. Permit fees are due at issuance, not at submittal.

Does Johnson County require a contractor license for Stilwell work?

Yes. Johnson County requires a contractor license for residential construction in unincorporated areas including Stilwell. The license classes that cover residential hardscape work are Class A (General), Class B (Building), Class C (Residential), and Class DS (Swimming Pool). For a residential paver patio with a pergola or pavilion, a Class A, B, or C contractor can pull the permit. A residential pool requires the Class DS swimming pool license in addition. Licensing requires either a passing ICC exam at 75 percent or a Bachelor's degree in architecture, engineering, construction science, or construction management.

What does a paver patio actually cost in Stilwell?

Most Stilwell paver patio projects land between $28,000 and $65,000 for the patio surface, with full outdoor living builds running $80,000 to $250,000+. The cost reflects the acreage character of the area: larger projects, premium material expectations, and longer access drives for the build. Bigger lots also tend to want more outdoor living square footage.

What requires a permit in unincorporated Johnson County (Stilwell)?

All decks, all roofs, all new structures, and any enlargement, alteration, repair, move, or demolition. Any residential structure with floor area exceeding 200 square feet requires a permit, which is a tighter threshold than most of the cities inside Johnson County. Pergolas, pavilions, outdoor kitchens, and outdoor fireplaces on footings are permitted at this threshold. Decks attached to the home are permitted regardless of size.

What are the residential pool rules in Stilwell?

Residential pools in unincorporated Johnson County require a Johnson County Class A, B, C, or DS contractor on the permit. The required barrier (fence or wall) details, including type, dimensions, gates, and installation dates, are submitted as part of the permit. The pool cannot be filled with water until the barrier is complete and a Certificate of Occupancy is issued. Pools must sit within the platted setback lines and outside of any utility easement.

Do I need a permit for a fence in Stilwell?

A building permit is not required for a residential fence unless it is over 7 feet tall. The 7-foot threshold is looser than most of the Johnson County cities (Shawnee and Lenexa, for example, run a 6-foot threshold for fence permits). For any fence under 7 feet you should still contact the Johnson County Planning Department at 913-715-2200 to confirm zoning setbacks and easement clearances for your specific lot.

What's different about building on a Stilwell acreage lot?

Three things change on a typical Stilwell project compared to a city-incorporated suburb. First, the lot is bigger, so the patio footprint and the access drive can both be bigger. Second, many Stilwell properties are on septic systems and well water rather than city utilities, which affects pool siting (10-foot lateral clearance from septic components is the binding rule) and patio drainage routing. Third, mature trees on acreage are usually the centerpiece of the lot, and tree protection is the most important non-negotiable on the build.

Hardscape Contractor in Stilwell, KS: What Acreage Homeowners Should Know

Stilwell is unlike the other Johnson County entries on this list. It's not a city. It's an unincorporated community in south Johnson County, mostly farmland that's been quietly turning into suburban estate properties for the last twenty years. There is no Stilwell city hall and no Stilwell building department. The jurisdiction for everything (permits, code, inspections, contractor licensing) is the County, specifically the Johnson County Department of Planning, Housing and Community Development.

That changes a few things on a hardscape project. The contractor needs a Johnson County license, not a city occupational license. The permit triggers are looser in some places (fences under 7 feet need no permit, retaining walls under 4 feet stay exempt) and tighter in others (any residential structure over 200 square feet needs a permit). The build itself usually sits on real acreage, often with septic and well rather than city utilities, which changes pool siting and drainage. What follows is what we'd tell a Stilwell homeowner before they sign anything.

Permits and the County

Johnson County is the building department.

The Johnson County Building Codes Division is the issuing authority. Reach them at 913-715-2200, Option 1 or planningandcodes@jocogov.org. Residential permits typically issue in 7 to 10 business days from a complete submittal, and permit fees are due at issuance, not at submittal.

For residential hardscape, expect to pull a permit for:

Any residential structure with floor area over 200 square feet. That includes pergolas, pavilions, outdoor kitchens, and outdoor fireplaces on footings.
All decks attached to the home, regardless of size.
All new structures, all roofs, and any enlargement, alteration, repair, move, or demolition of an existing structure.
Pools, spas, and hot tubs, with the barrier and Certificate of Occupancy rules below.
Retaining walls over 4 feet measured from the bottom of the footing to the top of the wall, or any wall supporting a surcharge.

What's exempt from a building permit:

Fences under 7 feet tall. Looser than most Johnson County cities (Shawnee and Lenexa run a 6-foot trigger for the fence permit). You still want to confirm zoning setbacks and easement clearances with the Planning Department before you set posts.
Retaining walls 4 feet or under measured from the footing, with no surcharge load behind them.
Detached accessory structures with floor area at or under 200 square feet, provided setbacks are met.

The 200-square-foot residential trigger and the 7-foot fence trigger are the two numbers a Stilwell contractor has to get right at the bid stage.

Contractor Licensing

Class A, B, C, or DS, depending on the work.

Johnson County requires a contractor license for residential construction in unincorporated areas, including Stilwell. The classifications that come into play on a residential hardscape project:

Class A (General). Covers all residential and most commercial scope.
Class B (Building). Covers commercial and residential building construction.
Class C (Residential Building Contractor). Covers single-family and duplex residences and accessory buildings, including framing, roofing, swimming pool construction, non-structural remodeling, and repairs.
Class DS (Swimming Pool). Required in addition to A, B, or C on any project that includes a pool.

Licensure requires either a passing ICC exam at 75 percent or higher, or a Bachelor of Science in architecture, engineering, construction science, or construction management from an ABET- or ACCE-accredited program. Subs (electrical DE, plumbing DP, mechanical DM, etc.) need their own classifications on permitted work.

For a Stilwell paver patio with a pergola, a Class A, B, or C contractor pulls the permit. For a Stilwell pool, the contractor needs to also hold Class DS. We carry the licensing required for the scope; the permit application can name us at submittal without delay.

The Pool Rule

Barrier first. Certificate of Occupancy before water.

Johnson County pool permits in Stilwell are specific about the sequence:

The contractor must hold Class A, B, C, or DS. The permit will not issue without it.
The barrier (fence or wall) details are part of the permit application, including type of barrier, dimensions, gates, contractor, and installation dates.
The barrier has to be installed and pass inspection before the pool is filled with water. Not after. The Certificate of Occupancy gets issued against the completed barrier, and the pool legally cannot be filled until that CO is in hand.
The pool has to sit within the platted setback lines and outside any utility easement.

On a Stilwell acreage lot we also have to clear septic system clearances. Many Stilwell properties are on septic. A 10-foot lateral minimum from any septic field component is the rule we work to, with the actual clearance often longer based on what the septic engineer specs for that lot.

Acreage Builds

What changes on a Stilwell lot.

Stilwell hardscape projects are different from a city-incorporated suburb project in a few practical ways:

The lot is bigger. The patio footprint and the outdoor living square footage scale up to match the home and the property. Pavilions and combined indoor-outdoor builds are common.
Mature canopy on big lots is the asset. Old oaks and walnuts on five-acre lots are not obstacles; they are the centerpiece of the design. Tree protection runs the build.
Septic and well, not city utilities. Pool siting respects the septic field. Patio drainage routes to a code-compliant outfall on the property, not to a city storm sewer.
Driveway and access matter. Long driveways, gravel sections, and gated entries change how we stage materials and how we time concrete deliveries.
HOA coverage is sparse. Some Stilwell-adjacent subdivisions (Polo Fields, Hallbrook, the newer estate neighborhoods on the Stilwell side of the line) run HOAs with architectural review. True rural Stilwell acreage usually does not. We confirm at the address-check step.

What It Costs

Real ranges from real Stilwell builds.

These are the numbers we've been hitting on Stilwell and south-Johnson-County acreage projects through 2026. Stilwell pricing skews to the upper end of the Johnson County range because the projects are bigger, the material expectations are premium, and the build typically includes more retaining and grade work to take advantage of the lot.

Frequently Asked

Stilwell homeowner questions.

How long does a permit take in Stilwell?

For a straightforward residential hardscape project, the county publishes a 7 to 10 business day turnaround from a complete submittal. Pools, walls over 4 feet with engineering, and accessory structures over 400 square feet add time on the front end. Submitting a clean, complete package the first time is the biggest variable.

Do I need a soil test for a Stilwell project?

For a standard residential patio with a wall under 4 feet, no. For engineered walls over 4 feet, the engineer typically either applies a soil bearing assumption based on south-Johnson-County norms or specs a site-specific soil test. We disclose at the engineering step whether a soil test is in the contract or not.

Does the City of Overland Park apply to my Stilwell property?

Only if your address is inside the Overland Park city limits, which now extend partway into what historically was Stilwell. Some addresses with a Stilwell postal designation are inside Overland Park; others remain unincorporated Johnson County. We verify jurisdiction at the address-check step before quoting. If your address is inside Overland Park, the OP rules apply and you can read our Overland Park guide.

Do I need HOA approval in Stilwell?

It depends on the specific subdivision. The newer estate neighborhoods on the Stilwell side often run an architectural review, while true rural acreage usually does not. We pull covenants for the specific lot at the design step and budget submittal time if it applies.

How soon can you start a Stilwell build?

Late fall through early spring we can typically be on site within 6 to 10 weeks of contract. Peak season (April through July) we're scheduling 12 to 20 weeks out. Pool builds and large pavilion builds add front-end time for engineering.

Do you handle the county permit submittal too?

Yes. The permit application, the plan set, the engineering when required, and the inspection coordination are all included as part of the contract. The homeowner doesn't have to chase the county.
