If you own land or are thinking about buying a lot to build on in Southwest Ohio, this guide walks you through every evaluation step. Click each item to check it off as you go.
Building on your own lot is one of the most rewarding ways to create a genuinely custom home — and one where the due diligence you do before breaking ground determines how smoothly everything goes. The buyers who have the best experiences did their homework first. This guide gives you a complete checklist, organized by phase. Click each item to mark it done.
Run these checks before committing to a purchase. Getting them wrong costs you either the deal or significant post-purchase expense.
A soil percolation test evaluates whether the lot will support a conventional septic system. Rural lots that fail require more expensive engineered systems or may not be buildable at a reasonable cost. Costs $300–$600 and should happen before closing.
Look up the lot’s NFIP flood zone designation. Property in a flood zone affects insurance, foundation requirements, and potentially your mortgage. Free public information — check it every time.
Know where the nearest electric, water, and sewer connections are and roughly what connection will cost. A lot with utilities at the road is very different from one requiring 800 feet of electric run and a well.
Check for utility easements, access easements, deed restrictions, and covenant limitations before closing. You don’t want to discover a 30-foot utility easement through your building site after you own the lot.
Contact the county or township planning office to confirm setback requirements. Once setbacks are applied, the actual buildable area may be considerably smaller than the total lot size suggests.
Have an experienced custom home builder walk the lot with you before closing. ACE will walk any lot with a prospective client at no cost. A 30-minute site visit can surface drainage issues, soil concerns, and access problems not visible in a listing.
Once you own the lot, these steps move you toward a successful build.
A geotechnical investigation confirms the foundation type your soil conditions require and whether any soil remediation is needed. This affects foundation cost and design directly.
You need a current survey to design a home on the lot, confirm setback compliance, and apply for building permits. If an existing survey is more than a few years old, confirm it’s still accurate.
If you’re on well water, the well site needs to be selected and approved before site design is finalized. Well location affects septic system placement and potentially the home’s position on the lot.
A licensed septic designer should evaluate your lot based on perc test results and planned home size. This must be done before your builder can finalize the site plan.
If your lot requires a curb cut on a state or county road, confirm it’s obtainable before finalizing the site plan. ODOT curb cuts on state routes can involve significant review timelines.
If the property is subject to HOA rules or deed covenants, review architectural standards carefully before design begins. Some covenants restrict home size, exterior materials, garage placement, or accessory structures.
Before your builder can finalize a design, you need clear answers to these questions.
Before any design begins, ACE wants to understand how your family lives — how you use your kitchen, how you entertain, what drives you crazy about your current home. These answers drive every design decision.
You don’t need a precise number, but you need an honest range that includes land, site prep, construction, soft costs, and contingency. The Cost of a Custom Home Ohio page has a complete framework.
Your builder needs to understand your priorities — where you want to invest and where you’re comfortable pulling back — to set realistic allowances and a reliable budget.
Custom home timelines depend on design complexity, site conditions, permit processing, and selections timelines. Understand the realistic timeline before design begins so you can plan financing and current housing.
Covered porches, outdoor kitchens, screened porches, and pools each affect site design and budget. Identify what outdoor living matters to you before the site plan is finalized, even if you plan to phase those elements.
ACE will walk any lot with a prospective client before they purchase — at no cost and with no commitment required. A 30-minute site visit surfaces conditions that significantly affect your build. This conversation is free. The surprises it prevents are not.
