- One-call center
- West Virginia 811 (WV811)
- Notice before digging
- Not less than 48 hours (excluding Saturdays, Sundays and holidays) nor more than 10 work days before work begins
- Ticket good for
- No expiration: none in state law, and WV811 says its tickets 'will no longer have an expiration date'
- Hand-dig zone
- 2 ft (24 in.): operators must mark within 2 ft horizontally of the facility's outside walls (W. Va. Code § 24C-1-3(d)(1))
- Homeowners
- Yes. 'Excavation' covers moving earth by 'any tools, equipment, or explosives' with no homeowner or hand-tool exclusion; only mining, tilling for agriculture or domestic gardening, and shallow paved-road maintenance are excluded. WV811 tells homeowners: 'Click or call before you dig. It's the law!'
- The law
- W. Va. Code ch. 24C, art. 1 (§ 24C-1-1 et seq.)
- Good to know
- WV811 suggests updating the ticket every 30 calendar days while work is active and requesting a remark if marks are no longer visible or accurate. A 2026 law, HB 4464 (effective June 7, 2026), set the 2-ft marking standard and tiered civil penalties but did not change the notice rules.
Drainage law and stormwater permits in West Virginia
- Rule
- Reasonable use
- The rule
- Reasonable use: in dealing with surface water a landowner may take only such steps as are reasonable, weighing the actor's advantage against the neighbor's disadvantage and social utility; reasonableness is usually a jury question.
- Leading case
- Whorton v. Malone. W. Va. S. Ct. App. No. 28724 (June 15, 2001); following Morris Associates, Inc. v. Priddy, 181 W. Va. 588, 383 S.E.2d 770 (1989)
- What it means for your yard
- Regrading, downspouts and patios are judged by whether your steps were reasonable, weighing your benefit against your neighbor's harm; good intentions alone don't make a harmful diversion reasonable.
- Construction stormwater permit
- West Virginia Department of Environmental Protection (WVDEP), Division of Water and Waste Management: 1 acre or more of earth disturbance: construction stormwater general permit WV0115924 (effective April 6, 2024 to April 5, 2029)
- State rules below 1 acre
- No statewide rule below the 1-acre permit found; check your county and town.
- Local rules
- West Virginia cities and counties may have their own grading, floodplain or stormwater ordinances.
- Good to know
- West Virginia judges drainage disputes by whether a landowner's steps were reasonable. State construction stormwater permits start at 1 acre.

Workers' comp requirements in West Virginia
- Who must carry it
- All West Virginia employers that regularly employ others must carry coverage (W. Va. Code § 23-2-1(a); WV Offices of the Insurance Commissioner). Not required (but may elect): employers of domestic workers, agricultural employers with 5 or fewer full-time employees, and casual employers with no more than 3 employees working no more than 10 days a quarter (§ 23-2-1(b)). No separate construction threshold.
- Owners and officers
- Covered by default but may be excluded by the business: partners, sole proprietors, certain corporate officers and board members (officers with separate duties may still be covered), and up to four LLC managers, officers or members in total (W. Va. Code § 23-2-1(d)).
- Subcontractors
- A subcontractor's employee can file a claim against the prime contractor if the sub was uninsured and not self-insured and the prime contractor didn't get a certificate of coverage from the sub; getting the certificate generally relieves the prime contractor. Subs must give the prime a certificate covering the contract term and notify it within two business days of a lapse. If the Uninsured Employer Fund pays a sub's worker, the prime and sub are jointly liable unless the prime did due diligence on the sub's coverage (W. Va. Code § 23-2-1d).
- Homeowners
- Employers of domestic workers are not required to carry coverage (W. Va. Code § 23-2-1(b)(1)).
- Penalties
- The Insurance Commissioner's Employer Coverage Unit assesses fines and license revocations for noncompliant employers (WV OIC).
- The law
- W. Va. Code Ch. 23; §§ 23-2-1, 23-2-1d
- State agency
- West Virginia Offices of the Insurance Commissioner, Employer Coverage Unit
- Good to know
- West Virginia requires coverage for nearly all employers with regular employees. Get a certificate of coverage from every sub; if you don't and the sub is uninsured, its injured workers can claim against you.

Frost dates in West Virginia
| Station | Last spring frost | First fall frost | Frost-free days |
|---|---|---|---|
| Charleston Kanawha Valley | April 16 | October 26 | 192 |
| Huntington Ohio River, west | April 14 | October 26 | 195 |
| Beckley Southern highlands | April 22 | October 21 | 180 |
| Elkins Allegheny Mountains | May 5 | October 12 | 159 |
- Typical range
- Last frost mid-Apr (Huntington) to early May (Elkins); first frost mid-Oct (Elkins) to late Oct (Charleston and Huntington)
- Good to know
- These are typical (50%) dates from NOAA's 1991–2020 climate normals, so about half of years still bring a 32°F night after the listed spring date. In West Virginia, the last spring frost at the stations listed ranges from mid-April around Huntington to early May around Elkins. WVU Extension's beginner guide uses zone dates (last frost April 20 to May 10, first killing frost October 5 to 20), generally a bit more cautious than these NOAA station dates.
