But finding truly buildable lots means verifying utilities, not just vacancy. Ploti cross-references utility service areas to find lots that are actually ready to build. This example uses **regional datasets** (Orange County urban service area, water service providers, wastewater service providers) to verify utility availability. Utility verification is available in areas where we've integrated local infrastructure data. [Learn more about regional data coverage](/getting-started/regional-data). ## The Opportunity Infill lots with verified utilities are valuable because: * Water and sewer connections already exist—no extension costs * Established neighborhoods with known comparable values * Shorter entitlement timelines than greenfield development * Strong buyer demand for new construction in desirable areas ## Walkthrough: Finding Buildable Residential Lots Let's find vacant residential lots that are truly development-ready—inside the urban service area with both water and wastewater service confirmed. ### Step 1: Select Your Search Area First, select the boundary you want to search within. Selecting a county as the search boundary ### Step 2: Ask the Question Asking Ploti to find vacant residential lots with utility service We asked: > Find vacant residential lots between 0.25 and 1 acre inside the urban service area with water and wastewater service available This query combines **four layers** in one request: * **Vacant residential** (land use codes 460, 465) * **0.25 to 1 acre** (single-family buildable size) * **Inside urban service area** (infrastructure zone) * **Water + wastewater service** (utility verification) ### Step 3: Review the Plan Ploti analyzes your request and creates a multi-layer analysis plan: Ploti's analysis plan showing data exploration across parcel and utility layers The agent identified: * **4,043 vacant residential lots** in the boundary * **963 lots** in the target size range (0.25-1 acre) * **12 water service territories** to check against * **5 wastewater service territories** to verify ### Step 4: Review Final Results Map showing 337 buildable infill lots with full utility service Ploti found **337 vacant residential lots** with verified utility access. | Filter Stage | Parcels | | --------------------------------------- | ------- | | All parcels in boundary | 64,352 | | Vacant residential lots | 4,043 | | Size filtered (0.25-1 acre) | 963 | | With urban service + water + wastewater | 337 | **65% of size-appropriate vacant lots lack full utility service.** Without utility verification, you'd waste time on lots that require expensive infrastructure extensions. ### Step 5: Analyze Distribution Ploti breaks down results by location and characteristics: | City | Parcels | Avg Size | Avg Market Value | | ------------- | ------- | -------- | ---------------- | | Winter Garden | 160 | 0.47 ac | \$89,795 | | Ocoee | 85 | 0.49 ac | \$51,602 | | Orlando | 73 | 0.54 ac | \$18,737 | | Gotha | 12 | 0.55 ac | \$77,576 | | Windermere | 5 | 0.69 ac | \$101 | | Oakland | 2 | 0.47 ac | \$113,330 | **Size distribution:** * 0.25-0.50 acres: 202 parcels (60%) * 0.50-0.75 acres: 84 parcels (25%) * 0.75-1.00 acres: 51 parcels (15%) ### Step 6: Explore Utility Service Layers Toggle on the supporting layers to visualize the utility infrastructure: **Urban Service Area** — The boundary where urban-level utilities are provided: Urban Service Area boundary overlay **Water Service Providers** — 12 different water utility territories: Water service provider territories overlay **Wastewater Service Providers** — 5 sewer utility territories: Wastewater service provider territories overlay These overlays help you understand which utility provider serves each lot—useful information when planning connections. ## Why Utility Verification Matters Finding a "vacant lot" is easy. Finding a **buildable** lot is harder. The difference: | Without Utility Check | With Utility Check | | --------------------------------- | -------------------------------- | | 963 vacant lots in size range | 337 lots with verified utilities | | Unknown infrastructure costs | Utilities confirmed available | | May require \$50-100k+ extensions | Ready for tap fees only | | Weeks of due diligence calls | Instant verification | Ploti's cross-layer analysis eliminates lots that look good on paper but have hidden infrastructure costs. ## The Time Savings Without Ploti, verifying utility availability would require: 1. Identifying vacant residential lots from county records 2. Filtering for appropriate lot sizes 3. Calling the county to determine urban service area boundaries 4. Calling the water utility to verify service availability 5. Calling the wastewater utility to verify sewer service 6. Repeating steps 3-5 for each lot of interest 7. Maintaining a spreadsheet to track which lots passed all checks **That's 15-20 minutes per lot for utility verification alone. For 963 candidate lots, that's 240+ hours of phone calls. Ploti did it in 2 minutes.** This is the kind of systematic screening that only large homebuilders with dedicated land acquisition teams could afford. Ploti puts the same capability in the hands of any builder or investor. ## Tips * Lots inside the urban service area typically have utility access, but verify tap fee costs with providers * Water and wastewater service areas don't always overlap—both are required for residential development * Check why attractive lots are still vacant—there may be easements, access issues, or wetlands * Compare assessed values to recent lot sales in the same subdivision * Consider lots that have been vacant longest—owners may be more motivated to sell ## Other Example Prompts ### Basic Vacant Lot Search > Show me vacant residential lots under 1 acre in Winter Park Simple search when you just need to find vacant lots in a specific area. ### Value-Based Infill Search > Find vacant residential lots under 0.5 acres inside the urban service area with market values under \$75,000 Adds a price ceiling for budget-conscious builders. ### Subdivision Infill > Find vacant lots under 1 acre within platted subdivisions that are zoned R-1 Targets lots in existing neighborhoods with single-family zoning. ### Infill Without Flood Risk > Find vacant residential lots between 0.25 and 1 acre with water service that are not in a FEMA flood zone Combines utility verification with environmental screening.
