# utility # utility The systems serving the property: heating, cooling, water, sewer, electrical, and the energy features recorded against them. The question it answers ## What is this house, physically? The feature vector, taken from the source of record rather than from a listing agent. Assessor and parcel records are authoritative; listing fields are agent-entered, inconsistent between markets, and absent entirely for a property that was never listed. Other classes answering this question ## Why it matters The utility set is a cost and a risk. Well and septic rather than municipal water and sewer changes the carrying cost, the inspection requirements and the financeability; an ageing heating system is a near-term capital call. The source dictionary carries no definition for this class. ## In practice The extraction is one of the five scripts written per jurisdiction, because utility recording is where county formats diverge most — the same heating configuration appears as a code in one county, a free-text description in the next, and a set of separate indicator fields in a third. ## Properties | Property | Type | Definition | | --- | --- | --- | | `source_http_request` | `object` | HTTP request configuration for retrieving this data. | | `request_identifier` | `string | null` | Identifier value that should be substituted into the source HTTP request to retrieve this specific data. | | `cooling_system_type` | `string | null` | Refers to the type of cooling system used in the structure. `CeilingFans``Electric``Ductless``Hybrid``CentralAir``WindowAirConditioner``WholeHouseFan``CeilingFan``GeothermalCooling``Zoned` | | `heating_system_type` | `string | null` | Refers to the type of heating system used in the structure. `ElectricFurnace``Electric``GasFurnace``Ductless``Radiant``Solar``HeatPump``Central``Baseboard``Gas` | | `heating_fuel_type` | `string | null` | Primary energy source used by the heating system. `Electric``NaturalGas``Propane``Oil``Kerosene``WoodPellet``Wood``Geothermal``Solar``DistrictSteam``Other` | | `public_utility_type` | `string | null` | Refers to the type of public utility available to a structure. `WaterAvailable``ElectricityAvailable``SewerAvailable``NaturalGasAvailable``CableAvailable``UndergroundUtilities` | | `sewer_type` | `string | null` | Refers to the type of sewer used in the structure. `Sanitary``Public``Combined``Septic` | | `water_source_type` | `string | null` | Refers to the type of water source used in the structure. `Well``Aquifer``Public` | | `plumbing_system_type` | `string | null` | Refers to the type of plumbing system used in the structure. `Copper``PEX``PVC``GalvanizedSteel``CastIron` | | `plumbing_system_type_other_description` | `string | null` | A free-form field to capture detail when Other is selected for the plumbing system type. | | `plumbing_fixture_count` | `integer | null` | Total number of plumbing fixtures installed in the property (e.g., toilets, sinks, urinals, floor drains) | | `plumbing_fixture_type_primary` | `string | null` | Primary type of plumbing fixture.
