Lot Selection in McCracken County: 7 Things to Check Before You Buy
Choosing the right lot is the decision that affects every other decision in your custom home build. The wrong lot can add $30,000–$80,000 to your construction cost before a single wall goes up. It can limit your design options, complicate your financing, and create problems that no amount of good construction management can fully solve.
Most homebuyers spend more time selecting their countertops than evaluating their lot. This is a mistake.
Here are seven things to check before you buy land in McCracken County — and why each one matters.
1. Utilities: What's Available and What It Costs to Connect
The first question to answer about any lot is what utilities are available and what it will cost to bring them to your building site. In McCracken County, the answer varies significantly depending on location.
City water in Paducah and most incorporated areas of the county is provided by Paducah Water. Sanitary sewer is managed by the Joint Sewer Agency (JSA). Connection fees and tap fees for both vary — confirm current rates directly with Paducah Water and JSA before budgeting, as the distance from the main to your building site affects cost.
Well and septic are required on most rural lots in the county. A well typically costs $8,000–$15,000 depending on depth and geology. A conventional septic system runs $6,000–$12,000 for a standard residential installation. If the lot fails a perc test — meaning the soil does not drain adequately for a conventional system — you may need an engineered alternative system, which can cost $15,000–$35,000 or more.
Electric service is available throughout the county. Within Paducah city limits, service is provided by Paducah Power System. In rural and unincorporated areas of McCracken County, service is typically provided by Jackson Purchase Energy Cooperative. Regardless of provider, the distance from the nearest transformer to your building site affects the cost of the service run — rural lots requiring a long service run can add $5,000–$20,000 to the project cost.
Natural gas is available in Paducah and many suburban areas but is not available on all rural lots. If you want a gas range, gas fireplace, or gas HVAC system, confirm availability before you buy.
Before making an offer on any lot, ask the listing agent for documentation of utility availability, or call the relevant utility districts directly. Do not assume.
2. Perc Test and Soil Conditions
If the lot requires a septic system, a percolation test (perc test) is essential before purchase. A perc test evaluates how well the soil absorbs water, which determines what type of septic system can be installed and where.
Lots that fail a conventional perc test are not necessarily unbuildable — but they require an engineered alternative system that costs significantly more and may restrict where the system can be located on the lot. In some cases, the required system footprint limits where the house can be placed.
Perc tests are typically conducted by a licensed soil scientist or engineer and cost $300–$600. This is one of the most important $500 investments you can make before buying land.
Soil conditions also affect foundation costs. Expansive clay soils, high water tables, and rock close to the surface can all increase foundation costs significantly. A geotechnical report — a soil boring and analysis — is not always required for residential construction, but on lots with unknown soil conditions, it is worth the cost.
3. Floodplain Status
McCracken County has significant floodplain areas, particularly near the Ohio River, the Tennessee River, and their tributaries. Before buying any lot, check its FEMA flood zone designation.
Lots in FEMA Flood Zone AE or VE require flood insurance, which adds to your annual carrying cost. More importantly, building in a floodplain requires the finished floor elevation of the home to be at or above the Base Flood Elevation (BFE), which may require fill, elevated foundations, or other measures that add cost.
You can check flood zone status using the FEMA Flood Map Service Center at msc.fema.gov. Enter the property address and review the flood zone designation before making an offer.
Even lots that are not in a designated floodplain can have drainage issues. Walk the lot after a heavy rain if possible, or ask neighbors about standing water. A lot that drains poorly will require grading and drainage work that adds cost and may limit your landscaping options.
4. Setbacks, Easements, and Deed Restrictions
Every lot in McCracken County is subject to setback requirements — minimum distances from property lines within which no structure can be built. Setbacks vary by zoning district and by the type of structure. In McCracken County residential zones (AG, RR, and UR), the minimum setbacks are: front yard 30 feet, rear yard 25 feet, and side yard 8 feet for principal structures (4 feet for accessory buildings). These figures apply to unincorporated McCracken County — if your lot is within the City of Paducah limits, the city's own zoning ordinance applies and setbacks may differ.
On a narrow lot, setbacks can significantly constrain the buildable area. A 75-foot wide lot with the required 8-foot side setbacks on each side has only 59 feet of buildable width — which limits both the footprint of the home and the placement of a garage.
Easements are portions of the lot that are reserved for utility access or other purposes. A utility easement along the rear of the lot may prevent you from building a detached garage or pool house in that area. Review the title commitment and plat carefully for any easements before closing.
Deed restrictions are private covenants that run with the land and may restrict what you can build, what materials you can use, or what activities are permitted on the property. Subdivision deed restrictions are common in planned developments and can affect everything from minimum square footage requirements to fence height and exterior color choices.
If the lot is in a platted subdivision, also confirm whether a Homeowners Association (HOA) exists. HOA membership typically comes with annual or monthly dues — fees that become a permanent carrying cost on the property. HOA rules can also restrict exterior finishes, outbuilding types, parking, landscaping, and short-term rental use. Some HOAs require architectural review and approval before construction begins, which adds time to your preconstruction process. Review the HOA declaration, bylaws, and current fee schedule before making an offer — these documents are typically available from the listing agent or the HOA management company.
5. Topography and Site Access
Flat lots are cheaper to build on than sloped lots — but they are not always more desirable. A gently sloping lot can allow for a walkout basement, better drainage, and more interesting architecture. A steeply sloped lot can require significant grading, retaining walls, and engineered foundations that add $20,000–$60,000 or more to the project cost.
Site access is a practical consideration that is easy to overlook. A lot that requires a long driveway adds cost — both to construct and to maintain. A lot that is not accessible by a standard delivery truck during construction creates logistical challenges for material deliveries. A lot with a steep or narrow access point may require special equipment for concrete pours and heavy material deliveries.
Walk the lot with a builder before you buy. What looks like a manageable slope on a plat map can look very different when you are standing on it.
6. Zoning and Permitted Uses
Confirm the zoning designation of the lot and verify that a single-family residence is a permitted use. In most residential zones in McCracken County, this is straightforward — but it is worth confirming, particularly on lots that are not in established subdivisions.
If you are planning to build a home with an accessory dwelling unit (ADU), a detached garage larger than a certain size, a home-based business, or any structure that is not a standard single-family residence, check the zoning ordinance before you buy. Variances are possible but not guaranteed, and the process takes time.
Also check whether the lot is subject to any overlay districts — historic districts, floodway overlays, or agricultural preservation zones — that may impose additional requirements or restrictions.
7. The Neighborhood Trajectory
This one is harder to quantify but important to consider. A lot is not just a piece of land — it is a position in a neighborhood, and neighborhoods change over time.
Look at what has been built nearby in the last five years. Are new homes going up? Are they comparable in quality and price to what you plan to build? A $600,000 custom home in a neighborhood where the surrounding homes are valued at $200,000–$300,000 will not appreciate at the same rate as the same home in a neighborhood of comparable or higher-value properties.
Also consider what is adjacent to the lot. A lot that backs up to a commercial property, a high-traffic road, or an industrial area may be priced attractively for a reason. Drive the neighborhood at different times of day and on different days of the week before you commit.
The Bottom Line
Lot selection is a decision that deserves as much attention as any other part of the custom home process. The seven items above are a starting point, not an exhaustive checklist. Every lot has its own characteristics, and the cost implications of those characteristics are not always visible from a listing photo or a plat map.
