Codes adopted
Nevada does not mandate a single statewide building code edition. Under NRS 278.580, the governing body of each city or county may adopt its own building code, specifying design, soundness, and materials of structures, together with rules and ordinances for enforcement — a home-rule framework in which each jurisdiction selects and amends its code independently. There is no state-mandated IBC or IRC edition. The one statewide floor is for energy: under NRS 701.220, the Governor's Office of Energy (GOE) is required to adopt the most recently published edition of the International Energy Conservation Code (IECC) on a triennial basis. Upon adoption by GOE, local governments must incorporate that edition as the minimum energy standard and may adopt higher or more stringent requirements. GOE adopted the 2024 IECC, effective August 18, 2024, pursuant to NAC 701.185. Because building code editions, local amendments, and energy code effective dates vary by jurisdiction across Nevada, always confirm the current adopted edition and any local amendments with your specific city or county before submitting plans.
Permit types & fees
Residential Building Permit (New Construction — Custom)
Required for construction of a new custom single-family home or townhome in Boulder City. Reviewed against the City's own adopted 2018 IRC and 2018 IECC (with Southern Nevada Building Code Amendments), plus Boulder City design criteria (115 mph wind, Seismic Zone D0, zero snow/frost load). Applications are submitted via email to buildingpermits@bcnv.org or through the online Permit Portal.
Residential Addition / Remodel Permit
Required for additions and remodels to existing single-family homes and townhomes in Boulder City, reviewed against the 2018 IRC, 2018 IECC, and other adopted codes with Southern Nevada Building Code Amendments.
Electrical Permit
Required for electrical installation, alteration, or repair work in Boulder City, governed by the 2017 National Electrical Code (NEC) with Southern Nevada Building Code Amendments.
Plumbing Permit
Required for plumbing installation, alteration, or repair work in Boulder City, governed by the 2018 Uniform Plumbing Code (UPC) with Southern Nevada Building Code Amendments.
Mechanical / HVAC Permit
Required for heating, ventilation, air conditioning, and related mechanical installations in Boulder City, governed by the 2018 Uniform Mechanical Code (UMC) with Southern Nevada Building Code Amendments.
Re-Roofing Permit
Required for re-roofing involving sheathing replacement in Boulder City. Reviewed against the 2018 IBC/IRC as adopted (with Southern Nevada Building Code Amendments). Re-roofing that does NOT involve sheathing replacement, or that installs additional layers within the allowed maximum, is exempt from permit under the Administrative Code; re-roofing involving sheathing replacement qualifies for the City's expedited 'Express Permit' (no-plans) track. There is no dedicated roofing fee table — the general valuation-based Building Permit Fee (Table A) governs.
Renewable Energy System — Residential Photovoltaic (PV) Permit
Required for installation of rooftop residential solar photovoltaic systems in Boulder City. Governed by the City's 2018 IRC, 2018 IBC, and 2017 NEC (with Southern Nevada Building Code Amendments), plus the City's Residential and Small Commercial Photovoltaic Permit Process guide. Net metering applies via the City's own municipal utility.
Demolition Permit
Required for demolition or relocation of any building or structure (or portion thereof) in Boulder City. Governed by 2026 Administrative Code Section 110.2(O) and, for properties in the Historic District, Title 11, Chapter 27 of the Boulder City Code.
Fence and Retaining Wall Permit
Required for fences and retaining walls in Boulder City above the exempt thresholds, reviewed against zoning height/setback standards (Section 11-20-4 of the Boulder City Code) and, for engineered walls, structural requirements per the adopted 2018 IBC/IRC.

Tips & gotchas
- Boulder City runs its own independent Building and Safety Division (Community Development Department) — it is NOT part of Clark County's building department and is independent from the Las Vegas Valley's multi-jurisdictional contractor-licensing reciprocity system. Contractors must hold a Boulder City business license.
- Nevada has no statewide building code; NRS 701.220 sets only an energy-code FLOOR via the Governor's Office of Energy's triennial IECC adoption (2024 IECC effective 8/18/2024 is the current statewide floor). Boulder City's own adopted IECC edition (2018, with Southern Nevada Amendments) predates the current statewide floor — this is a home-rule local choice, not a floor violation, since 2018 IECC was the floor when Boulder City last adopted its code cycle. Confirm current status with Building and Safety before relying on this edition.
- Boulder City's adopted code set (confirmed identically across eight separately-published, live permit-submittal checklists and the 2020 fee-schedule flyer) is: 2018 IBC, 2018 IEBC, 2018 IRC, 2018 UMC, 2018 UPC, 2017 NEC, 2018 ISPSC, 2018 IECC, and (per the 2020 flyer) 2012 IFC — all 'with Southern Nevada Building Code Amendments.' The City's 2026 Administrative Code (procedural/fee code only) references 'currently adopted' codes generically without repeating edition years inline.
- Six 'Express Permit' scopes require no plans: water heater replacement, HVAC replacement (same-for-same), service change (same-for-same), gas test, re-roof (sheathing only), and main breaker replacement.
- Per-permit-type first-review plan-review timelines are separately published and verified: Residential New Construction (Custom) 3-4 weeks; Fence and Retaining Wall / Residential Accessory Building / Residential Addition / Solar PV 2-3 weeks; Electrical / Plumbing / Mechanical / Demolition / Residential Remodel 1-2 weeks. Approved permits are then issued 1-2 business days after payment.
- The City's own published thresholds for accessory-structure permit exemption are internally inconsistent: the 2026 Administrative Code Section 106.2 states 200 sq ft (one-story detached accessory buildings), while the live FAQ page and the 'Residential — Accessory Building' checklist title both instead say '>120 SF in Size.' Applicants should confirm the currently enforced threshold directly with Building and Safety (702-293-9282).
- Fences without permanent foundations under 4 feet, and retaining walls under 24 inches (2 feet), are exempt from permits; a courtesy Planning site-plan review is still recommended for any fence per the Fence and Wall Guide.
- No dedicated Accessory Dwelling Unit (ADU) permit type, checklist, or ordinance was found published by the City of Boulder City's Building and Safety Division as of this review (its 26-checklist library covers new construction, additions, remodels, and specific trades/structures, but none titled or scoped as 'ADU'). Third-party ADU-rule-lookup sites exist but are not usable as sources per the grounded-data policy; a distinct verified ADU permit record could not be established.
- Demolition permits in the Historic District may be delayed up to 45 days under Title 11, Chapter 27, Section 11-27-6 of the Boulder City Code for historical-record creation and Historic Preservation Committee review.
- Boulder City is a municipal electric and water utility — solar PV net-metering, water-meter, sewer-connection, and electrical-service-connection fees in the Table H schedule are billed directly by the City (not a private utility), and the Building and Safety Division is described as the 'one stop shop' for permitting, fees, and inspections including forwarding solar net-metering paperwork to the utility side.
- All permit submittals are made by email to buildingpermits@bcnv.org (20MB per-email limit; larger packages via Dropbox/OneDrive) or through the online Permit Portal at bouldercitynv-permit-portal.azurewebsites.net (Google Chrome recommended); inspections are scheduled via a separate hotline (702-293-9327) or buildinginspections@bcnv.org, with a minimum one-business-day advance notice (3:30pm cutoff) and no Friday/weekend/holiday inspections.
