Building a custom home is exciting, but preparation is key. Here's what every Johnson County home buyer should know before breaking ground.
Building your dream home in Johnson County is an exciting journey, but it's important to go in prepared. As someone who specializes in new construction, I've helped dozens of families navigate this process successfully. Here are the five most important things you need to know.
1. Choose Your Builder Wisely
Not all builders are created equal. In Johnson County, we're fortunate to have some incredible builders, but you want to make sure you're working with someone who:
- Has a solid reputation and references
- Offers transparent pricing
- Communicates well throughout the process
- Stands behind their work with good warranties
I work closely with Kansas' most reputable builders and can help connect you with the right fit for your project and budget.
2. Understand the Timeline
Custom homes typically take 6-12 months to build, depending on size and complexity. Here's a general timeline:
- Design & Permits: 2-3 months
- Foundation: 2-4 weeks
- Framing: 3-6 weeks
- Mechanicals: 4-6 weeks
- Finishes: 6-10 weeks
Weather, change orders, and material delays can impact these timelines, so build in some buffer.
3. Budget for the Unexpected
Even with the best planning, expect to spend 10-20% more than your initial budget. Common unexpected costs include:
- Site preparation surprises
- Upgrade creep during selections
- Change orders mid-construction
- Landscaping and outdoor features
- Window treatments and final touches
4. Know Your Lot
The lot you choose will impact your home's design, cost, and timeline. Consider:
- Topography: Sloped lots may require additional foundation work
- Utilities: Are water, sewer, electric, and gas easily accessible?
- Restrictions: HOA rules and city codes that might limit your design
- Future development: What's planned for surrounding areas?
5. Have Professional Representation
This is where having an experienced Realtor becomes invaluable. I can help you:
- Navigate builder contracts and protect your interests
- Coordinate inspections at key milestones
- Communicate with your builder on your behalf
- Ensure you're getting everything you paid for
Here's something most buyers don't realize: builder sales agents work for the builder, not for you. Their job is to maximize the builder's margin. Having an experienced buyer's agent in your corner costs you nothing (the builder pays the commission) but can save you thousands on upgrade negotiations, lot premiums, and contract terms that favor the builder.
Johnson County's Best New Construction Communities in 2026
If you're ready to build, Johnson County has some excellent active communities to consider:
Sundance Ridge — Overland Park (66085)
One of the most active new construction communities in south Johnson County, developed by Rodrock with four builders — Rodrock, Walker Custom Homes, Symphony, and LG Homes. The community's $4M clubhouse with pools, gym, and indoor gymnasium makes it stand out for families. Homes range from the mid-$600Ks to low $900Ks. Blue Valley schools throughout.
Mills Farm — Overland Park (66221)
An established luxury community with some new construction still active through Braklow and Covenant. If you want the feel of a mature neighborhood with the option to build new, Mills Farm offers that rare combination. Blue Valley Southwest serves the community.
Spring Hill — Johnson County's Southern Corridor
Spring Hill is drawing builders because land is still available at prices that make larger lots feasible. If space matters as much as square footage, the new construction in Spring Hill delivers. USD 230 schools serve the area, with some northern parcels feeding Olathe schools.
The Decisions That Define Your Build
Beyond the five fundamentals, there are a handful of decisions that buyers consistently say — in hindsight — they wish they'd handled differently:
Basement configuration. Johnson County homes almost universally include a basement. Think carefully about whether a walkout matters to you (it commands a lot premium, but it also dramatically changes how you use the space). A finished basement adds immediate livable square footage; leaving it unfinished saves money upfront but costs more to finish later.
Lot orientation. South-facing backyards get the most sun. North-facing stay cooler in summer. If you have a strong preference for how you'll use outdoor space, lot orientation matters more than most people anticipate.
Upgrade prioritization. Builders present a dizzying menu of options during selections. As a general rule: prioritize structural options and hard-to-change features (ceiling height, windows, layout changes) over cosmetic finishes (countertops, flooring) that you can update later. Don't spend $30,000 in structural upgrades to save $5,000 on counters and regret it at year two.
