Can I build a duplex on a single-family lot in Nevada?

There is no statewide duplex mandate in Nevada. Whether a duplex is allowed on a given lot depends entirely on the zoning district assigned by the relevant city or, for much of the Las Vegas metro, unincorporated Clark County under Nevada Revised Statutes Chapter 278.

Are accessory dwelling units legal in Nevada?

It depends on the jurisdiction. Nevada has no confirmed statewide ADU mandate as of this writing, so whether an ADU is allowed on a given lot is set by that city's or county's own zoning code under Chapter 278 — check current legislative activity, since this is an area of active reform in several Western states.

Is the Las Vegas Strip governed by the City of Las Vegas zoning code?

Mostly not. Most of the Strip and large parts of the surrounding valley sit in unincorporated Clark County, so development there is governed by Clark County's Title 30 Unified Development Code rather than the City of Las Vegas's own Unified Development Code.

How do I look up zoning for a parcel in Nevada?

Nevada doesn't maintain a single statewide zoning GIS layer, so you need to identify the governing jurisdiction first — a city or, in unincorporated areas, the county — and then consult that jurisdiction's own zoning map, most of which are published through the relevant planning department's GIS portal.

Nevada zoning: how it works and what you can build

Nevada's development story runs through unincorporated Clark County as much as through Las Vegas itself — most of the Las Vegas Strip and much of the surrounding valley are governed by county zoning, not the City of Las Vegas's own code.

How zoning works in Nevada

Nevada delegates planning and zoning authority to cities and counties under a single state enabling statute, Chapter 278 of the Nevada Revised Statutes ("Planning and Zoning"), which governs master plans, zoning ordinances, and subdivision review, with additional regional planning coordination requirements applicable to the state's most populous county.

A distinctive feature for developers: much of what outsiders think of as "Las Vegas," including most of the Las Vegas Strip, is actually unincorporated Clark County, not the incorporated City of Las Vegas — meaning Clark County's own zoning code, not the city's, governs the resort corridor and large swaths of the surrounding valley. Reno, Henderson, Sparks, and North Las Vegas each administer their own municipal zoning codes independently.

Nevada has moved more slowly than neighboring Western states on statewide zoning preemption, and localities otherwise retain broad discretion over use, density, and dimensional standards under Chapter 278; any claim of a recent statewide ADU or duplex mandate should be checked against the current legislative session before being relied on, since none was confirmed at the time of writing.

Who holds the zoning power

Land-use authority in Nevada is delegated by statute, not assumed — these are the acts a zoning ordinance in Nevada has to trace back to.

Nevada Planning and Zoning enabling act Nevada Revised Statutes, Chapter 278: Core statute authorizing city and county master plans, zoning ordinances, and subdivision regulation.
Master plan requirement Nevada Revised Statutes 278.150: Requires planning commission preparation and governing-body adoption of a master plan before zoning implements it.

Major cities and their codes

The enabling act sets the ceiling; the municipal code is what a project is actually reviewed against. The 6 largest Nevada jurisdictions and the codes they administer:

Nevada — municipal zoning codes
City	Zoning code
Las Vegas	Unified Development Code of the City of Las Vegas Note: the Strip and much of the surrounding valley are unincorporated Clark County, not the City of Las Vegas.
Unincorporated Clark County	Clark County Code, Title 30 (Unified Development Code) Governs the Las Vegas Strip resort corridor and most of the metro's unincorporated growth areas.
Henderson	Henderson Municipal Code (Zoning) Second-largest city in the state; major master-planned-community activity in Green Valley and Cadence.
Reno	Reno Municipal Code, Title 18 (Land Development Code) Fastest-growing city in the Reno-Sparks metro; administers its own land development code independently of Clark County.
North Las Vegas	North Las Vegas Municipal Code (Zoning) Fast-growing outer-valley jurisdiction with significant vacant-land supply relative to Las Vegas proper.
Sparks	Sparks Municipal Code (Zoning) Reno-metro industrial and logistics growth center.

Parcel & GIS data

Nevada has no single statewide parcel GIS clearinghouse comparable to some neighboring states; parcel data is maintained separately by county assessors, with Clark County's GIS the largest and most actively maintained given the Las Vegas metro's parcel volume.

Real parcel geometry is already loaded for Unincorporated Clark County — see the zoning-by-city section above for a live district-and-parcel lookup there. That is not the same as a cited feasibility report: Chicago is still the only jurisdiction with bulk standards, § citations and a generated massing scheme.

Zoning by city

The statute sets who may zone; the city's own code sets what you can build. One guide per Nevada city below, explaining the district codes that appear on its zoning map — 69 district codes across Nevada so far.
