Utility Disconnections Before Demolition: What Must Be Confirmed?

1. Build a utility list from the project—not from assumptions

Start at the structure and walk outward. Photograph meters, panels, overhead drops, service masts, gas equipment, water entries, sewer cleanouts, communication boxes, HVAC equipment, wellheads, septic features and any visible private lines. Record what serves the building being removed and what also serves a structure that will remain.

A detached garage may share electric service with the house. An addition may cover an older line. A pool can have power, bonding, water and drainage components beyond the shell. Rural property may rely on a well, septic system or propane installation. The written list should match the actual site instead of a generic statement that “utilities are off.”

2. Separate provider disconnection from building-side work

The utility owner, a qualified electrical or plumbing contractor, the demolition contractor and the property owner do not automatically have the same authority. Provider-owned meters or service equipment may follow one process, while capping or modifying building-side wiring, piping or drains can require a qualified trade and inspection.

The scope should assign each task: request service termination, remove or retain a meter, disconnect equipment, cap a line, verify the result, obtain any required release and protect service that remains. 850 Demolition does not represent that ordinary demolition includes licensed utility work unless a qualified provider and the written agreement specifically assign it.

3. Understand what Sunshine 811 does—and does not do

Sunshine 811 tells excavators to submit a locate request before digging. Its current guidance says to notify at least two full business days before excavation, excluding the day of notice, weekends and applicable holidays, then confirm the responses from the listed member utilities before digging.

Locate marks show the approximate location of participating underground facilities near the described dig area. They do not disconnect service, certify a building safe for demolition or authorize work. Sunshine 811 also states that member utilities do not mark private facilities. The person doing the excavation is responsible for following the six-step locate process; the project team should document that responsibility rather than assume someone else handled it.

Where marks or responses conflict with the site, stop and resolve the discrepancy. Sunshine 811 describes a 24-inch tolerance zone from each outside edge of a marked facility and requires increased precaution within that zone. Current ticket instructions—not memory from a previous project—should guide the work.

4. Map private lines and systems separately

Lines after a meter, owner-installed electric to a shed, irrigation, low-voltage wiring, propane, pool equipment, septic components and well piping can fall outside ordinary member locating. Old properties can also contain abandoned lines that remain physically present even when service records are incomplete.

Ask the owner for surveys, as-built information, prior invoices and site knowledge, but do not treat memory as proof. A private locator or qualified specialist may be appropriate when records and visible evidence cannot establish the route. Equipment should not cross a septic tank, drain field, weak culvert or unknown buried installation merely because no public locate mark appears there.

5. Match the utility plan to the demolition boundary

Complete building removal can affect service differently from selective interior demolition. Interior work may require safe isolation of a circuit, fixture, appliance or branch line while the building remains active. Structural demolition can require service to be disconnected back to an approved point and remaining lines protected.

Write the stopping point beside each system. If the house stays and a garage goes, show which connections remain live. If the structure and slab are removed, include buried lines and penetrations in the review. If a pool shell or foundation is excavated, coordinate the locate area with the full digging footprint rather than only the visible concrete edge.

6. Use the responsible permitting authority for the address

Permit and documentation requirements depend on the property, jurisdiction and scope. Okaloosa County publishes a demolition permit package for commercial and residential work. Walton County publishes a specific demolition form, and its current guideline directs applicants to contact utility companies and make sure electricity, sewer, water and gas are disconnected before demolition begins.

Incorporated cities can use their own review or coordinate with county departments, so a mailing city alone is not enough. Confirm the parcel and current process before assigning responsibilities. Private association or property-manager approval can add access and work rules, but it does not replace government or utility requirements.

7. Keep proof with the project file

Useful records can include utility correspondence, disconnect or release documentation, permit conditions, locate ticket information, positive responses, private-locate findings, photographs and the names of responsible parties. The exact documents vary, so the goal is not a universal packet—it is a traceable file for the actual job.

Before mobilization, compare those records with the site. Confirm that retained services are clearly identified, marks remain visible, the demolition boundary has not changed and the locate ticket is still valid for the planned work. A scheduling date should follow these prerequisites rather than pressure the project team to skip them.

8. Stop when field conditions do not match the plan

Unexpected conduit, pipe, wire, tank, odor, arcing, leaking water or missing marks can signal a condition that needs immediate attention. Stop work, keep people clear and contact the appropriate utility, emergency service or qualified professional for the situation. Do not test an unknown line with demolition equipment.

Changes should be documented before work resumes. A new route, deeper excavation or expanded removal area can require an updated locate request, permit coordination or trade review. The safest plan leaves room to pause when the property reveals something the estimate could not verify.
