Florida Underground Utility Laws
Know your legal obligations before any excavation
📜 Florida Statute 556 — Fact 1 of 7
Underground Facility Damage Prevention and Safety Act
Every person or entity planning to excavate in Florida — whether homeowner, landscaper, or licensed contractor — is legally required to notify 811 at least 2 full business days (not 48 hours) before any underground digging. This applies to projects of any size, including fence post holes, tree planting, and minor utility repairs. "Business days" excludes weekends and state holidays — plan accordingly.
📡 SSOCOF — Fact 2 of 7
Sunshine State One-Call of Florida — FL's 811 Center
SSOCOF is Florida's state-designated one-call notification center. It processes excavation tickets 24 hours a day, 7 days a week, 365 days a year — including holidays. Once submitted, member utilities have 2 full business days to physically mark their underground lines with APWA color-coded paint or flags. Your ticket is valid for 90 calendar days. After 90 days, you must resubmit before continuing excavation, even if conditions haven't changed.
⚠️ Excavator Liability — Fact 3 of 7
FL Stat. 556.106 — You Break It, You Pay for All of It
Under Florida Statute 556.106, any excavator who fails to notify 811 before digging and subsequently damages a utility line is 100% liable for: all repair and restoration costs, emergency response fees, lost revenue claims from the utility, property damage to third parties, and personal injury claims. There is no statutory cap — a single natural gas line strike can result in $15,000+ in direct costs before legal fees.
✅ 811 Coverage — Fact 4 of 7
What 811 Marks: Public Utilities to Your Property Line
Florida's 811 system locates and marks all public/municipal utility infrastructure in the right-of-way: electric distribution lines, natural gas mains, potable water mains, sanitary sewer mains, stormwater drainage systems, telecommunications conduit, cable TV and fiber optic networks, and petroleum pipelines. Coverage extends only to your property line — everything on your private property is a separate locate.
❌ 811 Does NOT Cover — Fact 5 of 7
Private Lines Require a Separate Professional Locate
811 will not locate or mark: private irrigation systems and sprinkler heads, pool and spa equipment lines, outdoor landscape and path lighting wiring, private propane supply lines, dock and boatlift utilities, secondary electric service runs (meter to house), private sewer laterals and septic drain fields, or in-ground pet fence wire. These require a licensed private utility locator using GPR or EM technology — and are where most residential strikes actually occur.
🔧 FL Contractor Law — Fact 6 of 7
Licensed Plumbers (CFC) Must Call 811 — No Exceptions
Per Florida Statute 489.127, all state-licensed plumbing contractors holding a CFC license are legally required to call 811 before performing any underground plumbing work, including trenchless pipe repair, water service lateral replacement, sewer cleanout installation, and irrigation system work. A licensed CFC who skips this step risks both civil liability and Florida DBPR disciplinary action up to and including license revocation.
🚨 Post-Ian Enforcement — Fact 7 of 7
Fines Up to $10,000 Per Violation — Enforcement Increasing
Following Hurricane Ian's infrastructure damage in 2022, FDOT and Florida's major utility operators significantly escalated enforcement efforts. Commercial excavators face fines up to $10,000 per violation for failure-to-call offenses. Repeat violators face mandatory safety training and potential contract disqualification on public projects. Residential violators risk civil liability and policy voiding — many homeowner insurance carriers deny utility-strike claims when 811 wasn't called.

Pre-Dig Safety Checklist
16 items across 4 phases — tap each to mark complete
🛡️ Safety Compliance0 / 16 complete
📞 Phase 1 — Before You Call 811
✓
Gather your full project address, nearest cross streets, and county parcel/folio number
✓
Stake or flag the exact boundaries of your intended dig area before calling — size matters for utility notification
✓
Document your maximum excavation depth for each zone of the project — shallower zones are lower risk
✓
Confirm your project start date is at least 2 full business days after the 811 call — plan around weekends & holidays
🎫 Phase 2 — After 811 Ticket Issued
✓
Record your 811 ticket number — keep it on-site at all times during excavation (write on permit if applicable)
✓
Wait the complete 2 full business days — do not begin digging early even if some utilities have already marked
✓
Photograph ALL utility markings (flags and spray paint) before any equipment rolls — documentation protects you legally
✓
If any area appears unmarked after 2 business days, contact the specific utility directly before digging in that zone
🚜 Phase 3 — Day of Dig
✓
Maintain minimum 18-inch horizontal tolerance zone on each side of all APWA-marked utility lines
✓
Hand dig or use vacuum excavation within 24 inches of any marked utility — no mechanical equipment within this zone
✓
Post emergency numbers on-site: 911 for emergencies, FPL/utility emergency line, and (561) 316-7450 for plumbing strikes
✓
If you strike any unexpected utility — stop work immediately, evacuate the area, call 911 for gas or electric strikes
🔍 Phase 4 — Private Line Verification
✓
Schedule private utility locate for all irrigation lines, pool plumbing, and landscape lighting prior to excavation
✓
Identify all private propane supply lines — check near tank, along house foundation, and to any detached structure
✓
Request as-built drawings from your builder, HOA, or county building records for complex or older properties
✓
Verify private sewer lateral route from home to public main — often unlisted on utility maps and in unexpected locations

⭐ 5 Pro Tips from Our Licensed FL Team
1 Florida's sandy coastal soil causes irrigation lines to shift over time, especially after heavy rain events. Always private-locate on lots you've owned for years — the original as-builts may be completely wrong.
2 If your 811 ticket is approaching day 87–90, DON'T wait for it to expire. Call 811 for a renewal ticket proactively — there's zero cost and it keeps you legally protected without losing your dig window.
3 Post-Ian rule: if you find faded, damaged, or partially missing utility flagging from a previous project, call 811 again. Re-marking is free and takes only 2 business days — never assume old marks are still accurate.
4 Most Florida homeowner insurance policies include a "failure to call" exclusion. If you strike a utility without a 811 ticket on file, your claim for the resulting damages may be denied entirely — not just reduced.
5 GPR scanning through a concrete slab before cutting or coring is not optional — it's standard practice. Post-tension cables, rebar, and conduit run in all directions. A $300 GPR scan prevents a $25,000 structural disaster.
