Fence and sprinkler invoices in Utah: the photo shows new posts, the locate ticket shows someone called before digging

A contractor replaces the back fence at a fourplex you manage in Utah and invoices for “remove and replace 140 ft privacy fence, 18 posts set in concrete”. A month later a landscaper bills for trenching new sprinkler lines across the front lawn. Both send photos: a row of fresh posts, a neat trench. The photos may be perfectly real. But the risk in this kind of job is underground, and a photo of finished work doesn’t show whether anyone found out what was buried there before the digging started. Utah law requires a notice before digging, and that notice gets a number. This piece covers what that record is, what it doesn’t cover, and what to ask for before you pay. It is not legal advice.

Why the photo can’t answer the question

A fence post looks the same whether the hole beside a gas service line was dug carefully or blind. Paint marks on the grass in a “before” photo help, but they don’t say which job or which day they were made for, and one lawn with orange paint on it looks much like another. The record that answers the question is written by someone other than the contractor, and it carries a date and a location.

What Utah’s law requires before digging

The law is Utah Code Title 54, Chapter 8a, “Damage to Underground Utility Facilities”. Its core rule: “Before excavating, an excavator shall notify each operator with an underground facility in the area of the proposed excavation.” (Utah Code 54-8a-4(1)(a)). “Excavate” is broad. It means “an operation in which earth, rock, or other material on or below the ground is moved or displaced by tools, equipment, explosives, or demolition” (54-8a-2(7)), so post holes and sprinkler trenches count. The exceptions are narrow: the notice rule does not apply “if there is an emergency”, “while gardening”, or “while tilling private ground” (54-8a-4(1)(b)).

The notice goes to a statewide association that utility operators must join, and “Notice provided to the association constitutes notice to each operator that has facilities within the proposed excavation site.” (54-8a-4(5)). The law also sets the timing and the content. The notice may not be given “less than 48 hours before excavation begins” or “more than 14 days before excavation begins”, and it must include the proposed excavation’s anticipated “location, with reasonable specificity”, “dimensions” and “type” (54-8a-4(2)).

The 48 hours are business hours, not clock hours. The law defines them as a period “occurring during business days” that “begins at 8:00 a.m. on the first business day after notice has been submitted” (54-8a-2(10)). A notice called in on a Friday afternoon doesn’t clear digging on Saturday.

Two more rules matter for an invoice. “If more than one excavator will operate at the same excavation site, each excavator shall provide the notice required by this section.” (54-8a-4(4)). So a fence company that brings in a separate auger crew needs a notice for each. And “Notice given under this section is valid for 21 days from the day on which the notice is given.” (54-8a-4(6)(a)). A longer job needs a renewal.

The paper behind the job: the location request number

When the association receives a notice, it gives the excavation a number. The law calls it a “location request assignment”: “a number assigned to a proposed excavation by the association upon receiving an excavation notice” (54-8a-2(14)). This piece calls it the ticket.

After that, each utility has its own deadline. Within 48 hours of the notice, the operator must mark its underground facilities in the area or tell the excavator it has none there (54-8a-5(1)). “Each marking is valid for not more than 21 calendar days from the date notice is given.” (54-8a-5(3)). Before digging, the excavator must confirm that operators using the association’s electronic system “have responded through the association’s electronic positive response system”, and that the facilities have been marked or the operators have said there are none (54-8a-4(7)(a)). Near a mark, power equipment is off limits until the excavator finds the exact location “by excavating with hand tools”, unless the operator waives that in writing (54-8a-5.5(1)). The zone is 24 inches either side of the mark, or of half the marked diameter (54-8a-2(21)).

So a real ticket has a number from someone other than the contractor, a date, a described location and size of dig, and a record of which utilities answered. A photo of the finished fence has none of that.

What the ticket does not mark: your own lines

This is the part most likely to surprise a property manager. The utilities mark their own lines, not yours. “An operator need not mark an underground facility the operator does not own.”, and that “includes a water or sewer lateral or a facility running from a house to a garage or outbuilding” (54-8a-5(2)(e)). The law’s definition of “Operator” leaves out a property owner whose lines are on the owner’s property, serve only that property, and are “maintained under the operation and control of that owner” (54-8a-2(18)(b)).

So a valid ticket can come back clean while the existing sprinkler lines, the power to the site lighting or the detached garage, and the building’s own sewer lateral sit unmarked under the trench. If the invoice later adds a line for “repair irrigation main cut during install”, the ticket doesn’t settle whose problem that was. We didn’t research private locating services or what a contractor should do about lines the utilities don’t mark.

If a line was hit

An excavator whose digging contacts or damages a facility must “provide notice of the contact or damage including the location and nature of any damage immediately to the operator” and delay backfilling near it until the operator says to go ahead (54-8a-7(1)). If gas escapes or electricity discharges, the excavator must immediately notify “emergency responders, including 911 services” and the operator (54-8a-7(3)). The federal rule for gas and hazardous liquid pipelines says the same in its own words: the excavator must “Use an available one-call system before excavating” and report damage to the pipeline operator “whether or not a leak occurs” (49 CFR 196.103(a) and 196.107).

Why it matters to you as well as the utility: under Utah’s law, damage by an excavator who dug without complying with the notice section “is prima facie evidence that the excavator is liable for any damage caused by the negligence of that excavator” (54-8a-6(1)). The law also sets civil penalties (54-8a-8). Who ends up paying for a cut line at your property is a legal question we don’t answer. The ticket is the first thing anyone will ask for.

Checks before you pay

1. Ask for the ticket number and the date it was called in, for each crew that dug. Check that the address matches the invoice.
2. Compare the dates. The notice should come at least 48 business hours before the digging and no more than 14 days before it. The digging should fall within the 21 days the notice is valid, or there should be a renewal.
3. Compare the scope. The notice describes the location, size and type of the dig. A ticket for “replace 6 fence posts, back yard” doesn’t match an invoice for 18 posts along two sides of the lot.
4. Ask for the responses. If the association’s system shows each utility’s answer, a contractor who checked them before digging can show you what they said.
5. Ask how private lines were handled if the job crossed your own sprinkler, lighting or sewer lines, since the ticket doesn’t cover them.
6. Ask for the original photo files of the marks and the work, not pictures pasted into an invoice PDF, which have usually lost their camera record. Why, and how to ask for the originals.
7. Drop the photos in together with the same contractor’s photos from other properties. The checker marks any two files in the same batch that are the same file, even under different names. A “finished fence” reused from another job shows up that way. A new photo of the wrong fence won’t, which is why the ticket matters more than the picture.

A gap here is a question, not a finding. The ticket is usually in the contractor’s name, so you may simply never have been sent it. Planting work can fall under the gardening exception. A real emergency changes the rules. Marks that were disturbed get a new request (54-8a-4(8)), so a job can have more than one ticket. And a contractor who can’t produce one has told you something about their practice, not necessarily about this invoice’s price.

What we don’t cover

Only Utah’s law. Colorado, Idaho, Arizona and the other Mountain West states have their own one-call laws, with their own timing, and we haven’t read them. We didn’t read the association’s excavator’s guide, which the law points to for how marks are made, or any city or county permit rule for fences or irrigation.

Whether someone used AI on the photos

A photo of a new cedar fence is easy to generate now, and some generators write a mark into the file saying so. The checker reads those marks in photos, and the notes some phone editors leave when generative AI was used to alter a photo. A file with no such mark is not proven real. Most fakes and most genuine photos look the same to a file reader once they have been through a chat app or a screenshot. And a genuine photo of a fence is still only a photo: the ticket number is what says someone asked what was underground first.

The limits, stated plainly

• We read Utah Code 54-8a-2, 54-8a-4, 54-8a-5, 54-8a-5.5, 54-8a-6, 54-8a-7, 54-8a-8 and 54-8a-9 on the Legislature’s site (le.utah.gov), in the versions effective May 1, 2024, and 49 CFR part 196 and 192.614 on the eCFR, in November 2026.
• We did not read the association’s excavator’s guide, its ticket rules or its search tools, any other state’s law, or any local permit rule. We don’t say how to look a ticket up.
• Who is liable for a damaged line, and how the penalties in 54-8a-8 apply, are legal questions we don’t answer.
• A ticket shows someone gave notice of a dig at a place and time. It doesn’t show the work was done, the price was fair, or that private lines were found.
• Our example is made up. We don’t know how often digging invoices are padded or how often contractors skip the notice.
• A photo with no camera record is not a fake. Text messages, chat apps and many portals remove the record from genuine photos every day.
• Our checker gives no confidence score and does not judge a picture by looking at it. It reads what is in the file, in your browser, and uploads nothing. A file with no AI marker is not proven real.
• This is not legal advice.
