Bathroom Remodel — Nevada license requirements

01 The project

The starting point is the work itself — Bathroom Remodel in Nevada. The job determines which trades are involved, and the trades determine which license classifications may be required.

02 Jurisdiction

This project is evaluated for Nevada — a state that requires a contractor license at any price: NRS 624.700 makes it unlawful to engage in the business or act as a contractor, or to submit a bid, without an active license, and an unlicensed bid or contract is void ab initio. There is no statewide dollar threshold anywhere (a verified absence), the license belongs to the business and is qualified by an individual, the classification scopes live in the NAC, the Board sets a monetary ceiling and a mandatory bond — and NRS 624.035 lets every county and city require MORE. Nevada jurisdiction page.

03 Trade → license

Relations below are recorded per state — only this jurisdiction's classifications are shown.

Trades involved: Plumbing, Electrical, Tile, Framing, Drywall, Painting.

• May require C-2 — Electrical contracting confirmed S-NV-NAC-200 rule NV-ELEC-CLASS
  The electrical portions: C-2 with C-2f RESIDENTIAL WIRING (≤ 600 volts on structures ≤ 3 stories — the usual bathroom case; rule NV-ELEC-CLASS evaluates the facts, missing facts → NOT_DETERMINED). Electrical work is carved out of both the $1,000 repair exemption (NRS 624.031(6)(b)) and the out-of-class relief (NRS 624.220(4)(b)). Tile (C-20), drywall (C-3e/C-4e) and painting (C-4a) round out the components.
• Alternative path B-2 — Residential and Small Commercial confirmed S-NV-NAC-170 rule NV-REMODEL-CLASS
  Official alternative when the remodel adds enclosed space or includes new construction: B-2 Residential and Small Commercial (NAC 624.170(2)) — construction and remodeling of houses ≤ 3 stories above / 1 story below ground. The same rule (NV-REMODEL-CLASS) returns B-2 from the enclosed-space facts.
• May require B-7 — Residential Remodeling confirmed S-NV-NAC-170 rule NV-REMODEL-CLASS
  Prime credential for remodeling an existing detached single-family residence: B-7 Residential Remodeling (NAC 624.170(7)) — as long as the work does NOT increase existing enclosed space. The moment space is added, B-2 is required instead (rule NV-REMODEL-CLASS). No dollar trigger exists (NRS 624.700); the $1,000 repair exemption is unavailable (permit + trade carve-outs). The prime may not swallow the trade scopes: plumbing → C-1/C-1d, electrical → C-2/C-2f — NRS 624.220(4)(a) lets the B contractor take the multi-craft contract only where trade work is 'incidental and supplemental' (research §L.3).
• May require C-1 — Plumbing and heating contracting confirmed S-NV-NAC-190 rule NV-PLUMBING-CLASS
  The plumbing portions require C-1 (C-1d: sanitary supply/waste/vent, fixtures, potable-water heating; C-1g if new gas piping enters the building). Work of a plumbing contractor is expressly named in the NRS 624.031(6)(b) carve-out — the $1,000 repair exemption never covers it. Local plumbing permit: LOCAL_AUTHORITY_REQUIRED (research §L.3).

04 Scope

What the official sources say about the work involved — typed assertions, never a boolean "covers". Interpretations are marked as such.

• Officially included C-1 Pipes And Vents For Lp And Natural Gas Into Buildings (may_perform) NAC 624.190 (C-1g) S-NV-NAC-190
  The gas-piping boundary next to C-1h water heaters (connection to EXISTING gas lines is C-1h; new piping into the building is C-1g).
• Officially included B-7 Remodeling And Improvement Of Existing Detached Stand Alone Single Family Residences (may_perform) NAC 624.170(7) S-NV-NAC-170
  No dollar trigger of any kind — Nevada has no licensing threshold (REQ-NV-NO-THRESHOLD-001).
• Officially included C-1 Any C 1 Subclassification Work (may_perform) NAC 624.190 S-NV-NAC-190
• Officially included C-1 Plumbing Systems Sanitary Drainage Hydronic Heating Irrigation Potable Water Heating And Building Edge Piping (may_perform) NAC 624.190 (C-1d) S-NV-NAC-190
  The plumbing answer for fixtures, vents and potable-water systems (bathroom-remodel page).
• Officially included C-1 Installation Replacement And Repair Of Water Heaters With Connections Venting (may_perform) NAC 624.190 (C-1h) S-NV-NAC-190
  The water-heater-replacement page's license answer, verbatim — rule NV-PLUMBING-CLASS. This subclass exists within primary C-1; it is not a separate license (FAQ #10).
• Officially included C-1 Heating Evaporative Cooling And Air Circulation Systems Including Solar Equipment (may_perform) NAC 624.190 (C-1f) S-NV-NAC-190
  The non-refrigeration heating/evaporative-cooling path — rule NV-HVAC-CLASS picks C-1f vs C-21 from the equipment facts.
• Officially excluded C-1 Cooling Systems Which Use Refrigeration As An Integral Part Of The System (may_not_perform) NAC 624.190 (C-1f) S-NV-NAC-190
  Half of the C-1f/C-21 heating-cooling boundary that rule NV-HVAC-CLASS evaluates.
• Officially excluded B-7 Increasing The Existing Enclosed Space Of The Residential Structure (may_not_perform) NAC 624.170(7) S-NV-NAC-170
  The home-addition boundary in one sentence — rule NV-REMODEL-CLASS evaluates facts remodel_adds_enclosed_space / project_adds_enclosed_space and returns B-2 when space is added. Also why the standalone home-addition page is withheld: the answer is fully determined by this row + NRS 624.700 (research §L/§R).
• Officially included C-2 Residential Wiring Up To 600 Volts On Structures Up To 3 Stories (may_perform) NAC 624.200 (C-2f) S-NV-NAC-200
  The usual residential electrical answer — rule NV-ELEC-CLASS evaluates the voltage/story facts (missing facts → NOT_DETERMINED).
• Officially included B-2 Construction And Remodeling Of Houses Up To 3 Stories Above And 1 Story Below Ground (may_perform) NAC 624.170(2) S-NV-NAC-170
  The answer when a project adds NEW enclosed space or is new construction — including home additions, because B-7 may not increase enclosed space (SCOPE-NV-B7-NO-ADD). Rule NV-REMODEL-CLASS picks B-2 vs B-7 from the enclosed-space fact.
• Officially included C-2 Electrical Wires Fixtures Apparatuses Raceways Conduits And Wind Energy Conversion Systems (may_perform) NAC 624.200 S-NV-NAC-200
• Officially included C-2 Photovoltaic Cells Batteries And Inverters Up To The Service Panel (may_perform) NAC 624.200 (C-2g) S-NV-NAC-200
  The PV-electricity leg of the three-way solar boundary: PV roof tiles replacing roofing = C-15a; PV cells/batteries/inverters to the panel = C-2g; solar thermal = C-37 (research §D).

05 Requirements

06 Rule: NV-ELEC-CLASS

Electrical classification (NAC 624.200): C-2f RESIDENTIAL WIRING covers current not exceeding 600 volts on structures not exceeding three stories above the ground; exceeding either limit needs the fuller C-2/C-2a scope; photovoltaic installation is C-2g (PV cells, batteries, inverters — not electrical wires beyond the service panel). Missing facts yield NOT_DETERMINED.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-NAC-200

07 Rule: NV-REMODEL-CLASS

Prime classification for residential work: remodeling an existing detached stand-alone single-family residence without increasing enclosed space → B-7 Residential Remodeling (NAC 624.170(7), which expressly does NOT authorize increasing existing enclosed space); adding enclosed space or new construction → B-2 Residential and Small Commercial (NAC 624.170(2)). Missing facts yield NOT_DETERMINED.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-NAC-170

08 Rule: NV-PLUMBING-CLASS

Plumbing classification (NAC 624.190): plumbing work → C-1 primary license (C-1d PLUMBING scope incl. potable-water heating); water-heater installation/replacement/repair → C-1h WATER HEATERS verbatim scope; new gas piping into the building is C-1g (same C-1 license — subclasses combine under one primary classification, FAQ #10). Missing facts yield NOT_DETERMINED.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-NAC-190S-NV-624-031

09 Rule: NV-LICENSE-REQUIRED

Statewide licensing decision (NRS 624.700): it is unlawful to engage in the business or act in the capacity of a contractor in Nevada, or to submit a bid on a Nevada job, without an ACTIVE license — and a bid or contract submitted in violation is void ab initio. There is NO statewide dollar threshold (verified absence): license is required for construction/alteration regardless of price, subject only to the NRS 624.031 exemptions (SEPARATE rules NV-REPAIR-EXEMPT, NV-OWNER-BUILDER). Missing facts yield NOT_DETERMINED.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-624-700S-NV-624-020S-NV-FAQ

10 Rule: NV-SPECIALTY-INCIDENTAL

Scope relief for LICENSED contractors (NRS 624.220(4)): (a) two-or-more-craft contracts are allowed where the other crafts are 'incidental and supplemental' to the licensed craft; (b) out-of-classification work is allowed if its value is under $1,000 including labor and materials AND no permit is required — NEVER for plumbing, electrical, refrigeration or air-conditioning work. This is not the NRS 624.031(6) exemption for unlicensed persons (separate rule NV-REPAIR-EXEMPT). Missing facts yield NOT_DETERMINED.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-624-220

11 Rule: NV-DEPOSIT-LIMIT

Residential deposit cap (NRS 624.970(2)(g)): for a contract with the owner of an OCCUPIED single-family residence for work concerning a residential improvement, the initial down payment must not exceed the LESSER of $1,000 or 10 percent of the aggregate contract price — unless the contractor filed a $100,000 consumer-protection bond or holds NRS 624.270(5) bond relief. The 10% limb needs caller arithmetic (the engine performs none), so a deposit above $1,000 is definitively over-cap, a deposit within $1,000 triggers the published 10% test, and relief facts switch the cap off. Missing facts yield NOT_DETERMINED.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-624-970

12 Rule: NV-PERMIT-GATE

State→local permit dependency: NRS 624.970(6) obliges the RESIDENTIAL contractor to 'apply for and obtain all necessary permits'; NRS 624.035 lets every county/city require ADDITIONAL local licensing; and the City of Las Vegas (LOCAL EXAMPLE — labeled, not statewide) requires a valid Nevada State Contractor's license AND a city business license for contractor permit issuance. Missing facts yield NOT_DETERMINED.

13 B-7 vs B-2 — the enclosed-space line, and the deposit cap

The prime credential turns on one physical fact: whether the remodel increases existing enclosed space. B-7 RESIDENTIAL REMODELING covers remodeling and improvement of the existing structure but may NOT increase enclosed space (NAC 624.170(7)); the moment space is added, or new construction is involved, B-2 is required (NAC 624.170(2)). Rule NV-REMODEL-CLASS never guesses — missing facts return NOT_DETERMINED. S-NV-NAC-170

The B contractor may take the multi-craft contract only where the trade work is "incidental and supplemental" to the licensed craft (NRS 624.220(4)(a)) — plumbing and electrical are never swept in by the out-of-class relief, which expressly excludes them (rule NV-SPECIALTY-INCIDENTAL). No dollar trigger exists for the construction itself (NRS 624.700), and the $1,000 repair exemption is unavailable here: the permit and trade carve-outs each defeat it independently. S-NV-624-031

14 Local permit layer

The state decides WHO MAY CONTRACT; the local authority decides permits, inspections, fees and any local business license. NRS 624.035 expressly lets each county or incorporated city require an additional contractor's license "subject to the applicant meeting such additional standards as are reasonable and necessary for the protection of the public" — the OPPOSITE of Georgia's preemption. NRS 624.970(6): the residential contractor "shall apply for and obtain all necessary permits." S-NV-624-035

The researched local example is the City of Las Vegas (LOCAL EXAMPLE — NOT STATEWIDE): "Only a Nevada licensed contractor may obtain a building permit for commercial construction" and "A valid Nevada State Contractor's license and city of Las Vegas business license are required for the issuance of permits to contractors" — the state license and a city business license both gate permit issuance, and the page publishes example local fees (labeled examples, never a fee schedule). S-NV-LV-FEE-EST

Permit fees beyond those labeled examples, exemption lists, timelines and every other city's or county's rules are LOCAL_AUTHORITY_REQUIRED.
