You only build a custom home once, so the lot you choose matters as much as the floor plan. In Charlotte and Mecklenburg County, a beautiful piece of land can hide rules, technical hurdles, and cost traps that change what you can build and how long it takes. If you want a smooth path from concept to keys, the right due diligence up front is your best protection.
This guide walks you through the essentials to evaluate a Charlotte-area custom-build lot with confidence. You will learn how to verify zoning, utilities, soils, trees, floodplains, permits, timelines, and resale drivers. Let’s dive in.
Zoning defines what you can build
Charlotte regulates land use through a Unified Development Ordinance. Zoning sets your minimum lot size, setbacks, building height, lot coverage, and allowable uses. It also guides parking and site access. Inside city limits you follow city rules, while unincorporated areas follow county rules. If a property sits near a boundary, annexation history or extraterritorial jurisdiction can change which rules apply.
A zoning check is your starting line. A narrow lot can limit your house footprint and rooflines. Height limits can affect views or second-story plans. Lot coverage caps can influence outdoor living, pools, and accessory structures. Confirm the zoning district on official parcel and zoning maps and verify any overlays that could apply.
Your zoning action list
- Confirm the property’s zoning district and permitted uses before you make an offer.
- Note required setbacks and lot coverage to estimate the buildable envelope.
- Ask about height limits and any overlays that affect design or parking.
- If you are in an HOA, review covenants and architectural guidelines for additional design controls.
Verify utilities early
Utility access can make or break a lot. Public water and sewer access varies across the Charlotte metro. Many in-town areas have sewer, while outlying sites may not. If there is no public sewer, you will need an on-site septic system that must be permitted by county environmental health.
Beyond water and sewer, factor in electric, gas, and telecom. Utility providers offer service maps, extension policies, and cost estimates. Long runs and transformer upgrades can add both time and money to your project.
Water and sewer
- Request a written serviceability or availability letter from the utility to confirm connections and capacity.
- If sewer is not available, schedule a percolation test and site evaluation with Mecklenburg County Environmental Health to confirm septic feasibility and size.
- Ask for tap fee schedules and any special connection requirements so you can budget accurately.
Electric, gas, and telecom
- Contact providers for service locations and extension costs.
- Identify where transformers, meters, and conduits will sit relative to your preferred house placement.
- Build utility timelines into your overall schedule to avoid delays at framing or finish stages.
Study topography and soils
Slope and soil are two of the biggest cost drivers you can control with smart due diligence. The degree and direction of slope dictate foundation type, driveway approach, retaining walls, and drainage strategies. The lot’s orientation also affects natural light and view corridors.
Soils vary across Mecklenburg. A site-specific geotechnical report is essential for foundation design. Expansive clays, shallow rock, or a high water table can increase excavation, require piers, or change your foundation type. A small investment in soils testing can save far more during construction.
What to order
- Boundary and topographic survey to capture grades, trees, and drainage features.
- Geotechnical investigation by a licensed engineer to guide foundation design and quantify risk.
- Drainage analysis to plan safe runoff and avoid downstream impacts.
Watch floodplains and wetlands
Floodplain and wetland constraints can take a portion of the lot out of play. Flood Insurance Rate Maps and local floodplain layers identify regulated zones. Building in a flood zone may require elevating the structure, adding floodproofing, and carrying flood insurance.
Streams, wetlands, and riparian buffers may be regulated by state and federal agencies. Jurisdictional wetlands or protected buffers can reduce your buildable area and redirect your driveway or pool location. If your lot is near mapped waters, consult the proper agencies and licensed consultants early.
What to verify
- Check the property against current floodplain maps before you write an offer.
- If a stream or wet area is present, engage a qualified professional to assess jurisdiction and buffer limits.
- Confirm any conservation easements or recorded buffers on the survey and title work.
Map easements and setbacks
Do not assume you can build anywhere within the property lines. Water, sewer, drainage, or access easements can cross the lot. Setbacks reduce the buildable footprint, and recorded covenants can further guide walls, fences, and outbuildings.
A current boundary survey will identify visible encroachments and recorded easements. Title review will surface other encumbrances. Combine these with your zoning setbacks to outline a realistic building envelope.
Survey and title essentials
- Order an updated boundary survey. If a lender requires it, obtain an ALTA/NSPS survey.
- Have your attorney review title for easements, covenants, and restrictions.
- Ask a civil engineer to overlay setbacks, easements, tree save areas, and topography on a single site plan.
Understand tree and stormwater rules
Charlotte’s tree protection and tree-save requirements can influence your site layout. Specimen trees might be protected and require mitigation if removed. Heavy tree cover can increase clearing costs but also add shade and privacy.
New construction must also follow stormwater rules that manage runoff and downstream impacts. Depending on your site, you may need engineered detention or retention, along with erosion control and a graded site plan. These measures protect neighbors and the watershed and are part of your permit path.
Practical tips
- Commission a tree inventory if canopy or specimen trees are present.
- Plan protective fencing and staging areas to safeguard roots during construction.
- Include engineered stormwater measures in your early budgeting to avoid surprises at permit review.
Plan permits, timeline, and budget
Your permit path depends on location and site complexity. Inside the City of Charlotte, you will work with Planning and Building, along with the water utility. In unincorporated areas, you will coordinate with county agencies. Wetlands or stream impacts add state or federal coordination.
Timelines vary by workload and site complexity. Straightforward lots may cycle through in several weeks. Complex sites with grading, stormwater, tree mitigation, or utility extensions can take several months. Build enough runway into your purchase contract and construction loan.
Typical steps
- Zoning confirmation and optional pre-application discussion.
- Boundary and topographic surveys, geotechnical testing, and perc test if needed.
- Site plan review for grading, stormwater, tree save, driveway, and utility connections.
- Building permit application and plan review for structural, mechanical, and energy.
- Inspections and final sign-offs before occupancy.
Budget drivers to expect
- Utility tap and impact fees and potential utility main extensions or transformers.
- Off-site improvements such as sidewalk or curb if required.
- Grading, erosion control, retaining walls, and engineered drainage.
- Tree clearing and any required mitigation or replacement planting.
- Foundation premiums for steep slopes or challenging soils.
- Septic design and installation if sewer is not available.
- Professional fees for surveying, engineering, and environmental reports.
Market and resale context in Charlotte
A lot is both a homesite and an investment. Compare recent sales of similar lots and new construction in the immediate area to estimate finished-home value and lot premium. Street type, nearby amenities, and access to shopping and transportation influence demand and future resale.
Assigned public school zones can affect buyer interest. Verify current assignments and stay aware of planned changes or new school construction. Also review local planning maps and recent rezoning to spot upcoming development. New roads, nearby commercial uses, or multifamily projects can change future traffic, privacy, and value.
Step-by-step due diligence checklist
Use this order of operations to protect your timeline and budget.
Pre-offer essentials
- Verify the zoning district and permitted uses.
- Confirm public water and sewer availability. Request a utility serviceability letter.
- Ask the seller for any existing surveys, plats, covenants, or disclosures.
- Check floodplain layers and note any mapped streams or wetlands.
- Review parcel tax history and relevant comparable sales.
During the contingency period
- Order an updated boundary survey. Obtain ALTA if your lender requires it.
- Add a topographic survey and tree inventory if slope or canopy matter.
- Commission a geotechnical report and drainage analysis.
- If no sewer, schedule a percolation test and septic site evaluation.
- Request written utility cost estimates for taps and any extensions.
- Perform a title review for easements, liens, and covenants.
- Confirm any HOA rules and architectural guidelines.
- If near mapped waters, consult the appropriate agencies for wetlands or buffers.
- Ask a local custom builder for site work and build cost estimates based on surveys and soils.
- Speak with the permitting office about likely reviews and timelines.
After closing, pre-construction
- Finalize engineered site, grading, erosion control, and stormwater plans.
- Submit applications for permits and utility connections.
- Build contingencies into your construction budget for unknown site conditions discovered during clearing and excavation.
Smart financing for lots and builds
Lot loans often carry higher rates, larger down payments, and shorter terms than standard mortgages. Lenders also tend to require a current survey and may request soils or site plans that show utility connections. Construction loans typically require approved plans, budgets, and builder credentials.
If your project needs a septic system, many lenders will ask for a signed permit or proof of a passing perc test before closing. Speak with your lender early so you can time inspections, permits, and approvals to match your financing milestones.
Common red flags and how to respond
- No public sewer and a failed perc test. Consider alternative septic designs, investigate nearby sewer mains for potential extension, or be prepared to walk away.
- Extensive utility extensions. Request written quotes and factor added time before committing.
- Steep slopes or poor soils. Expect foundation premiums and plan for retaining walls or piers.
- Large protected trees. Rework the layout to preserve canopy or budget for mitigation and replacement.
- Wide easements or tight setbacks. Reconfigure the house footprint or confirm if variances are an option.
