What Utilities Does the Land Have? How to Check Before You Buy

A land listing says utilities are available. The photos show a power pole by the road. What the listing does not say is whether that pole can serve your building site, where the water main ends, or whether any company will install internet at that address.

Utilities are often the largest cost between buying land and living on it, and the bill depends mostly on how far the parcel sits from the nearest line. Two parcels can look identical in a listing and differ by thousands of dollars in what it takes to turn the lights on.

Three phrases that sound alike

Five utilities matter: electricity, water from a public system or a well, sewer or septic, natural gas or propane, and internet and cell. For each one, a parcel is in one of three states, and listings blur them together.

At the road. A main or primary line runs in the public right-of-way along the frontage. Reaching your building site from it means a line extension, a lateral, a transformer, or a tap, mostly at your cost.

At the property line. The line reaches the edge of the parcel, which is where many utilities draw the line for available. Charlotte County, Florida, for example, treats a home as a mandatory sewer connection once "a wastewater collection line exists in an easement or right-of-way that abuts the property line" and gives the owner 180 days to pay the fees and connect. Available in that sense means you can connect, and in Charlotte County it means you must. Florida law backs that up: under s. 381.00655(1)(a), the owner of a properly functioning septic system generally must connect to an available sewer "within 365 days after written notification" that it is available, so a parcel sold as septic can carry a future sewer bill.

Connected. A meter is set, the tap or capital fee is paid, and an account can be opened. Only this stage means service exists today.

Internet has a federal test of its own. Under the FCC's Broadband Data Collection rules, a provider reports fixed service at a location only where it has built out its network and can perform a standard broadband installation with no network-extension charges, through "routine installation that can be completed not later than 10 business days after the date on which the service request is submitted."

The right-of-way line and the parcel line can be a few steps apart, and the cost difference is the whole extension. A mapping app such as Regrid shows where the boundary sits relative to the road and the poles, and how to find property lines covers the rest.

What listing phrases really mean

Listings are written to sell, and each utility needs its own answer.

Even a utility's own ZIP code check is area-level. Peoples Gas, a Florida natural gas distributor, tells a user with a positive result to call "to see if it's in your neighborhood" anyway. The ZIP is not the parcel.

How to verify each utility

Electricity: find the utility, then get a written estimate

Electricity comes from an investor-owned utility, a municipal utility, or a rural electric cooperative, and assigned territory decides which one serves a parcel. State utility commissions usually publish territory maps. Florida's Public Service Commission posts one for each kind, and each carries the same warning: "Service areas are approximations. Information on this map should be used only as a general guideline. For more detailed information, contact individual utilities."

Then ask that utility for a written line extension estimate to the spot where you plan to build. Utilities often absorb part of the cost through a free-footage allowance or a construction credit, and policies differ widely. Suwannee Valley Electric Cooperative in north Florida credits each residential extension with the "Average cost to build 1,200 feet of overhead primary" as its policy puts it, a credit set at $10,946 for January 2026, and the member pays any job cost above it. Its estimates are valid for six months. Utility Cost Guide, reviewed October 2, 2026, says allowances vary so much that "the same 500-foot run can cost nothing with one utility and $7,500 or more with another."

See the cost to run electricity to land for more.

Water and sewer: the availability letter and the fees

A public water or sewer utility can tell you whether a main is near the parcel, whether it has capacity to serve you, and what it will charge. Ask for all three in writing. Many utilities issue a will-serve letter or letter of availability. Two examples show the range.

Miami-Dade County's letter is informational: "This letter only advises you that water and sewer mains are available to service the project." Its conditions hold for 30 days, and it gives no vested right to service. Coachella Valley Water District in California issues its letters after connection fees are paid, and they "shall remain valid for eighteen (18) months from the date of issuance" unless a permitting agency requires an earlier expiration. If a seller hands you a letter, check the date and read exactly what it promises.

Two Florida counties show the fee scale.

Orange County's two charges add up to $8,060 before any pipe is laid on the lot. Pasco's fees step up each October, so ask for the schedule in effect when you expect to connect. Impact fees are separate and come at the building stage. In Florida, for impact fees adopted or increased after July 1, 2026, the Impact Fee Act says collection "may not be required to occur earlier than the date of issuance of the building permit" for the property.

County GIS can show service areas before you call. Pasco County's Water Service Areas layer "Includes all private and municipal water service providers" and has a wastewater companion, and many counties publish something similar.

No public service: wells and septic

Where no main is within reach, water means a well and sewer means septic, and both shift responsibility to you. The EPA states it plainly: "The quality and safety of drinking water from private domestic wells are not regulated by the Federal Government under the Safe Drinking Water Act nor by most state governments and laws." The county health or environmental office issues well and septic permits, and the soil decides whether septic is possible at all. Read what a perc test is before buying septic-dependent land, and see drilling a well and septic system cost and types for costs.

Gas: natural gas or propane

Ask the gas company whether a main runs on your road and what an extension costs. HomeGuide's January 2026 guide notes that "Some gas companies cover the installation costs up to a specified footage." Without a main, the answer is propane delivered to a tank on the property, so ask a local supplier about delivery and the cost to set a tank. If a tank is already there, find out who owns it. North Carolina's LP-gas regulator says that in that state, "Most of the time in North Carolina, when a propane company sets a tank, they keep ownership of it. This is especially true for above ground tanks." Practice varies by state, so ask whose tank it is.

Internet: the FCC map, then the provider

Start with the FCC National Broadband Map and enter the exact address or place the pin on the parcel. For fixed service it shows "which providers report making broadband service available at that location and the types of service or technologies and the maximum advertised download and upload speeds they each offer." NTIA's January 2024 BEAD guidance counts fiber, cable, DSL, and fixed wireless on licensed or hybrid spectrum as reliable broadband service, and the rest as alternative technology, which "includes unlicensed fixed wireless (ULFW) and low-earth orbit satellites (LEOs)." That is a funding classification, not a consumer rating, but a parcel with only those options listed has no wired choice.

If a provider refuses, quotes more than its standard installation fee, or cannot schedule within 10 business days, the map was wrong for that location, and those are among the FCC's listed grounds for an availability challenge:

• "Provider failed to schedule a service installation within 10 business days of a request"
• "Provider requested more than the standard installation fee to connect this location"
• "Provider denied the request for service"

A challenge corrects the map. It does not get you internet.

Cell signal: test it where the house will go

The FCC map's mobile layer shows where a phone should connect outdoors or in a moving vehicle, and "the map does not show indoor coverage." The only reliable check is to stand at the building site with the phones you actually use. The FCC Speed Test App is the FCC's own tool, and the on-the-ground tests it records are the evidence the FCC requires from individual consumers to support a mobile coverage challenge.

What it costs to bring in what is missing

Dated ranges from cost guides are the best public starting point. Every one is an estimate, not a quote.

The two headline totals do not match, and that is the honest picture. Use them to decide whether a parcel deserves a closer look, and the utility's written estimate to decide whether to buy. For clearing, a driveway, and permits on top, see what it costs to develop raw land.

Put utilities in the contract

Two protections belong in every land offer.

A contingency. Make the purchase depend on your being satisfied with utility availability and cost within a stated period. The Florida Realtors Vacant Land Contract builds this in: its Due Diligence Period, 30 days if the blank is left empty, lets the buyer investigate "availability of access to public roads, water, and other utilities" and, if the property is unacceptable and written notice reaches the seller on time, cancel with the deposit returned. The same form offers a No Due Diligence Period box. Checking it declares the buyer satisfied "that either public sewerage and water are available to the Property or the Property will be approved for the installation of a well and/or private sewerage disposal system" along with zoning and other restrictions. Check that box only if you have already done the work.

Written answers. Get the territory confirmation, the estimate, the availability letter, and the fee schedule in writing, and keep them with the contract.

Confirm the contingency wording with a licensed real estate attorney in your state, since forms and deadlines differ. See how to make an offer on land for the other contingencies.

Who to call: a one-page checklist

Electricity. The state utility commission map or county GIS for the serving utility, then that utility's new-service desk for a written estimate, the allowance or credit, and its expiration.

Water. The water utility for an availability letter, capacity, fees, and where the main ends. The county health or environmental office for well rules if there is no public water.

Sewer. The sewer utility for an availability letter, mandatory connection rules, fees, and planned expansions. The county health or environmental office for septic requirements if there is no public sewer.

Gas. The gas distributor for whether a main is on the road and the extension charge. A propane supplier for delivery, tank cost, and who owns any tank on site.

Internet and cell. The FCC National Broadband Map, then each listed provider for whether it will install at this address within 10 business days at the standard fee. The satellite provider's map for the exact address. Your own phone at the building site with the FCC Speed Test App.

Everyone else. The seller for copies of any letters or estimates, and the county building department for impact fees.

See the land due diligence checklist and the free checklist for the rest.

The bottom line

Utilities available means almost nothing until you know which utilities, where each line stops, and what the utility will charge to reach your building site. Find the utility, get the estimate and the availability letter in writing, check the FCC map and then call the provider, and stand on the site with your phone. Put a utility contingency in the offer so the answers can change your price, or your mind, before your deposit is at risk.
