Nebraska residential building code
- Code
- 2018 International Residential Code, excluding section R313 and chapters 25-33 (Nebraska state building code, Neb. Rev. Stat. § 71-6403)
- How it applies
- Statewide minimum, local amendments allowed
- Code agency
- None; set by statute (Nebraska Building Construction Act)
- Who enforces it
- Counties, cities and villages that adopt a code must use the state code or one that conforms generally with it; if they fail to adopt one within two years of a state update, the state code applies there by default (except farm construction). Enforcement is local.
- Good to know
- Nebraska's state code is the 2018 IRC without its sprinkler requirement. Local codes must generally match it, but permits and inspections depend on your city or county.

Retaining wall permits in Nebraska
- Permit exemption
- Set locally. Nebraska's state building code (2018 IRC) carries the model 4 ft R105.2 exemption, but counties, cities and villages administer their own codes and may amend permit and inspection provisions (Neb. Rev. Stat. 71-6406). There is no state permit program for homes.
- Who decides
- Your city or county decides.
- Good to know
- The state code includes the model 4 ft exemption, but cities, counties and villages can change permit rules. There's no state permit program for homes, so check with your local building office.

811 dig law in Nebraska
- One-call center
- Nebraska 811
- Notice before digging
- At least 2 full business days, but no more than 10 business days, before excavation
- Ticket good for
- 17 calendar days after the excavation start date on the ticket (14 calendar days after a remark)
- Hand-dig zone
- 18 in. on either side of the marking, plus half the facility width
- Homeowners
- Yes. Nebraska 811: 'Nebraska State law requires anyone who digs to place a locate request.' 'Excavation' covers tools, equipment or explosives; exclusions are limited to tilling and gardening for seeding/agricultural purposes, normal road maintenance, graves/landfills, some railroad work and hand digging at pole bases.
- The law
- Neb. Rev. Stat. § 76-2301 et seq. (One-Call Notification System Act)
- Good to know
- The 17-day ticket life is set by Neb. Rev. Stat. § 76-2323(3)(a), effective Sept 1, 2024. Nebraska 811 says to place a refresh ticket if work isn't done by day 14, and a refresh needs a 2-business-day wait.
Drainage law and stormwater permits in Nebraska
- Rule
- Modified common enemy
- The rule
- Modified common enemy (label assigned): diffused surface water may be dammed, diverted or otherwise repelled if necessary and without negligence; but once it concentrates in a natural depression, draw, swale or other drainway, it must be allowed to pass. The Nebraska Supreme Court itself calls this the 'common-law rule' and says it rejected the strict common enemy doctrine.
- Leading case
- Romshek v. Osantowski (quoting Nichol v. Yocum). Romshek v. Osantowski, 237 Neb. 426, 466 N.W.2d 482 (1991); Nichol v. Yocum, 173 Neb. 298, 113 N.W.2d 195 (1962); see also Tall Grass Hills, L.L.C. v. Overholt, Neb. Ct. App. No. A-23-114 (May 7, 2024) (memorandum opinion, not designated for permanent publication)
- What it means for your yard
- You can generally keep diffuse runoff off your land if it's necessary and done without negligence, but you can't block or reroute water that runs in a natural swale or draw, and careless drainage work can make you liable.
- State statute
- Neb. Rev. Stat. 31-202 defines a watercourse (a depression or draw at least two feet below the surrounding land with a continuous outlet), and 31-201 lets owners drain land in the general course of natural drainage into a natural watercourse or depression without liability when the drain is wholly on their land (both quoted in Romshek).
- Construction stormwater permit
- Nebraska Department of Water, Energy, and Environment (DWEE; formerly NDEE): 1 acre or more of land disturbance, or less than 1 acre if part of a common plan of development or sale: NER210000 Construction Storm Water General Permit
- State rules below 1 acre
- No statewide rule below the 1-acre permit found; check your county and town.
- Local rules
- Nebraska cities and counties often require their own grading or stormwater permits for smaller projects.
- Good to know
- Nebraska lets landowners repel diffuse runoff when necessary and done carefully, but water in a natural draw or swale must be allowed to pass. State construction stormwater permits start at 1 acre.
Contractor licensing in Nebraska
- Statewide rule
- Registration
- Agency
- Nebraska Department of Labor – Contractor Registration
- Who needs it
- All contractors and subcontractors doing business in Nebraska must register with the Department of Labor.
- When it applies
- All contractors doing business in Nebraska (no dollar threshold listed)
- Check a contractor
- Official lookup
- Good to know
- Registration does not test a contractor's skill.

Contractor deposits and your right to cancel in Nebraska
- Deposit limit
- No statewide cap.
- Right to cancel
- Home solicitation sales of $25 or more made away from the seller's place of business: may cancel until midnight of the third business day after the seller gives the required notice (Neb. Rev. Stat. §§ 69-1601, 69-1603). Buyer-requested repair visits, signed emergency waivers and mail/phone-only sales are excluded.
- The law
- Neb. Rev. Stat. §§ 69-1601 to 69-1607 (Home Solicitation Sales)
- Good to know
- In Nebraska the 3-day cancel clock doesn't start until the seller gives you the written cancellation notice.

Mechanics lien deadlines in Nebraska
- Lien deadline (prime)
- Record the lien within 120 days after final furnishing of services or materials (Neb. Rev. Stat. § 52-137).
- Lien deadline (sub/supplier)
- Same as prime.
- Preliminary notice (sub/supplier)
- Optional notice of right to assert a lien to the contracting owner (Neb. Rev. Stat. § 52-135), but against a 'protected party' (an owner who occupies or intends to occupy residential real estate of up to 4 units) a sub's lien is limited to the lesser of its unpaid amount or what remained unpaid on the prime contract when the owner received that notice (§§ 52-129, 52-136). In practice, send it early.
- Notice of intent
- Not required. Send the contracting owner a copy of the recorded lien within 10 days after recording (Neb. Rev. Stat. § 52-135(3)).
- Enforce within
- Enforceable for 2 years after recording; cut to 30 days after a written demand to sue from the owner or other interested person, unless the claimant sues or records an affidavit that the contract price isn't yet due (Neb. Rev. Stat. § 52-140).
- Homeowner rules
- Payments a homeowner makes in good faith before receiving a recorded lien or notice of right to assert a lien are protected (Neb. Rev. Stat. § 52-136). For protected-party homeowners, sub liens are capped by the unpaid prime contract balance when notice arrives.
- The law
- Nebraska Construction Lien Act, Neb. Rev. Stat. §§ 52-125 to 52-159
- Good to know
- On a Nebraska homeowner's job, a subcontractor who sends the owner a notice of right to assert a lien early protects more of its claim, because the owner's good-faith payments made before the notice reduce the lien.

Workers' comp requirements in Nebraska
- Who must carry it
- The Act covers employers in Nebraska who employ 1 or more employees in their regular trade, business, profession or vocation (Neb. Rev. Stat. § 48-106(1)). Exceptions include household domestic servants in a private residence, agricultural operations with only related employees, and agricultural operations with unrelated employees unless they have 10 or more unrelated full-time employees on each working day for 13 weeks in a calendar year (§ 48-106(2)). No separate construction threshold.
- Owners and officers
- Sole proprietors, partners, LLC members and self-employed persons working substantially full time in the business are not covered unless they elect coverage in writing with the insurer. Executive officers owning 25% or more of a corporation's stock are not employees unless they elect coverage in writing; officers owning less are covered (Neb. Rev. Stat. § 48-115(9)-(10)).
- Subcontractors
- A person who uses a 'scheme, artifice or device' (such as contracting work out) to avoid comp responsibility is treated as the employer, jointly liable with the immediate employer. This does not apply to an owner who in good faith hires a contractor, or a contractor who in good faith hires a sub, and requires that contractor or sub to carry comp from an insurer licensed in Nebraska (Neb. Rev. Stat. § 48-116).
- Homeowners
- Court decisions annotated to § 48-116 hold that an owner who hires a worker to remodel or move a residence is not an employer under the Act, even if the owner earns rental income from it (Neb. Rev. Stat. § 48-116, annotations).
- Penalties
- Civil fine of up to $1,000 per violation, with each day of continued failure a separate violation; if criminally charged, up to one year in jail, a $1,000 fine, or both; employers can be enjoined from doing business in Nebraska until they comply (Nebraska WCC employer FAQ).
- The law
- Neb. Rev. Stat. Ch. 48, Art. 1; §§ 48-106, 48-115, 48-116
- State agency
- Nebraska Workers' Compensation Court
- Good to know
- Nebraska requires coverage with one employee in your regular business. Require every contractor or sub you hire to carry comp from a Nebraska-licensed insurer, which protects you from liability for their workers.
