In Overland Park, KS, we provide custom home builder services for residential projects. Our crews travel southbound on US-69 (Metcalf Ave.) from Olathe. They enter Overland Park via the 135th Street exit. Each project is supported by our barndominium construction team and our basement finishing contractor specialists. Regional licensing details and full project coverage are listed on our Johnson County custom home builder service area page.
The dominant soil in Overland Park is Wymore-Ladoga montmorillonite clay. The USDA-NRCS rates it "very high" for shrink-swell behavior. During summer drought, this clay contracts 3–4 inches vertically. Slab heave and drywall cracking are documented in homes under five years old.
Former farmland lots throughout the Hallbrook area present a separate risk. Backfill on these lots was placed without engineered compaction. Differential settling is common on those sites.
Johnson County's Residential Foundation Guideline sets the minimum footing depth at 36 inches. This meets the frost line requirement for this zone. All structures also fall under a 90 mph wind-load design requirement.
Wymore-Ladoga clay behavior changes block to block. No standard spec covers every Overland Park lot. Engineered foundation design before the first footing is non-negotiable on any Hallbrook-area build.

The City of Overland Park Building Safety Division oversees all residential permits. Applications are filed through the ePLACE online portal. Questions can be directed to their office at 913-895-6220. Overland Park has adopted the 2018 IBC as its governing building standard.
An active Johnson County Contractor License is required before any permit will be issued. No exceptions.
Builders working in Blue Valley communities face an added step. HOA Architectural Review approval is required before construction begins. This process runs on a separate track from the city permit. Two approvals. Two timelines. Both are required.
The correct sequence looks like this. First, secure an active Johnson County Contractor License. Second, submit the HOA Architectural Review application for Blue Valley communities. Third, file the permit application through ePLACE with engineered foundation plans. Fourth, wait for Building Safety Division review and permit issuance. Fifth, schedule all required inspections per 2018 IBC milestones.
Hallbrook Farms is our most active project zone in Overland Park. It sits south of 135th Street near Metcalf Ave. This is an established, high-end subdivision with ongoing custom build activity.
The Indian Creek Library and Trail System corridor runs along 151st Street and Antioch. This marks the southern edge of our active project zone. Lots in this corridor carry the same clay and code challenges as Hallbrook Farms.
Hallbrook-area lots sit over heavily backfilled former farmland. That backfill was placed without engineered compaction in most cases. We have documented 3–4 inch seasonal shrink cycles across multiple sites in this area. Managing clay movement starts with engineered foundation design. Not after the first footing. Before it.

Yes. We provide onsite estimates throughout Overland Park. Our crews access the city via US-69 (Metcalf Ave.) from Olathe. We cover both the Hallbrook Farms area and the Indian Creek corridor at 151st and Antioch. Contact us for current estimate turnaround timeframes.
Wymore-Ladoga clay requires engineered foundation design before ground breaks. The USDA-NRCS rates this soil "very high" for shrink-swell behavior. Seasonal vertical movement runs 3–4 inches during summer drought. Former farmland lots carry additional risk from uncompacted backfill. Differential settling on those sites is well-documented.
Yes. We hold an active Johnson County Contractor License. Permits are pulled directly through the ePLACE portal. For builds in Blue Valley communities, we also manage the HOA Architectural Review process. That approval runs on a separate track from the city permit. We handle both.
Once permits are issued through the City of Overland Park Building Safety Division, site work can typically begin within 1 to 3 weeks. This timeline depends on weather conditions, utility locates, and excavation scheduling. For Blue Valley projects, both permit approval and HOA Architectural Review must be complete before mobilization. We coordinate all pre-construction steps to prevent delays.
Yes. Every Overland Park build we take on includes engineered foundation plans specific to Wymore-Ladoga clay conditions. We work directly with structural engineers to account for shrink-swell movement and lot-specific soil behavior. This is completed before permit submission to meet Johnson County requirements and prevent structural issues after construction.
Yes. We regularly build on Hallbrook-area lots with known backfill and settling concerns. These sites require additional evaluation, including soil testing and engineered foundation adjustments. Solutions may include deeper footings, pier systems, or soil stabilization methods. Each plan is designed per lot conditions to meet code and long-term performance standards.
