Key facts: 811 call is FREE; ticket valid 90 days; max fine $10K; strike risk $15K+; 2 business days notice required.
Florida Underground Utility Laws
Fact 1 — Florida Statute 556 (Underground Facility Damage Prevention and Safety Act): every person planning to excavate (homeowner, landscaper, or contractor) must notify 811 at least 2 full business days before any underground digging — any size, including fence posts and tree planting. Business days exclude weekends and state holidays.
Fact 2 — SSOCOF (Sunshine State One-Call of Florida): FL's state-designated one-call center, processing tickets 24/7/365. Member utilities have 2 full business days to mark lines with APWA color-coded paint/flags. Ticket valid 90 calendar days; resubmit after.
Fact 3 — Excavator Liability (FL Stat. 556.106): an excavator who fails to notify 811 and damages a line is 100% liable for repair/restoration costs, emergency response fees, lost revenue claims, third-party property damage, and personal injury. No statutory cap — a single gas line strike can exceed $15,000 before legal fees.
Fact 4 — 811 Coverage: locates all public/municipal infrastructure in the right-of-way (electric distribution, gas mains, potable water mains, sanitary sewer mains, stormwater drainage, telecom conduit, cable/fiber, petroleum pipelines). Coverage extends only to your property line.
Fact 5 — 811 Does NOT Cover (private lines need a separate professional locate): private irrigation/sprinklers, pool/spa equipment lines, landscape/path lighting wiring, private propane lines, dock/boatlift utilities, secondary electric service runs, private sewer laterals and septic drain fields, in-ground pet fence wire. Most residential strikes occur on these.
Fact 6 — FL Contractor Law (FS 489.127): all CFC-licensed plumbing contractors must call 811 before any underground plumbing work (trenchless repair, water service lateral replacement, cleanout install, irrigation work). Skipping risks civil liability and DBPR discipline up to license revocation.
Fact 7 — Post-Ian Enforcement: commercial excavators face fines up to $10,000 per violation for failure-to-call. Many homeowner insurers deny utility-strike claims when 811 wasn't called.

|---|---|---|---|---|
| GPR (Ground Penetrating Radar) | $150–$2,500+ | High | All line types, slabs, non-metallic PVC | Accuracy drops in wet/clay soils |
| EM Locating (Electromagnetic) | $95–$450 | Med-High | Metallic pipes, conduit, gas lines | Cannot detect non-metallic |
| Potholing (Test Pit) | $200–$600/loc | Exact | Depth verification, crossings | Slow, requires backfill/permits |
| Vacuum Excavation (Hydrovac) | $350–$900/hr | Exact | Urban dense areas, safe exposure | Requires mobilization, water source |
Pre-Dig Safety Checklist
Phase 1 — Before You Call 811: gather full address, cross streets, parcel/folio number; stake/flag the dig area; document max excavation depth per zone; confirm start date is at least 2 full business days after the call.
Phase 2 — After Ticket Issued: record ticket number (keep on-site); wait the full 2 business days; photograph all markings before equipment rolls; contact specific utilities for any unmarked zone.
Phase 3 — Day of Dig: maintain 18-inch tolerance zone each side of marks; hand dig or vacuum-excavate within 24 inches of any marked utility; post emergency numbers on-site; if you strike a utility, stop, evacuate, call 911 for gas/electric.
Phase 4 — Private Line Verification: schedule private locate for irrigation, pool plumbing, landscape lighting; identify private propane lines; request as-built drawings; verify private sewer lateral route.

5 Pro Tips from Our Licensed FL Team
- FL's sandy coastal soil causes irrigation lines to shift over time, especially after heavy rain. Private-locate on lots owned for years — original as-builts may be wrong.
- As ticket approaches day 87–90, call 811 for a renewal proactively (zero cost) without losing your dig window.
- If you find faded/damaged/missing flagging from a previous project, call 811 again. Re-marking is free and takes 2 business days.
- Most FL homeowner policies include a 'failure to call' exclusion — strike a utility without a ticket and your claim may be denied entirely.
- GPR scanning through a concrete slab before cutting/coring is standard practice. Post-tension cables, rebar, and conduit run in all directions; a $300 GPR scan prevents a $25,000 structural disaster.
