What is the Las Vegas Form‑Based Code?

It is Chapter 19.09 of the Las Vegas zoning code. Instead of sorting land mainly by use, it sets rules for building form: height, placement, frontage and the street it faces. It was adopted in October 2018 and is applied to downtown one district at a time.

Form first, use second

Conventional zoning, often called Euclidean zoning, starts with use. A parcel is residential, commercial or industrial, and the numbers that follow (setbacks, lot coverage, parking ratios) are there to keep those uses apart. The result is predictable in one sense and unpredictable in another. You know what the building will be used for, but not much about what it will look like from the sidewalk.

A form-based code turns that around. The Form-Based Codes Institute, whose definition the Las Vegas code quotes, describes it as a regulation that

fosters predictable results and a high-quality public realm by using physical form (rather than separation of uses) as the organizing principle for the code.

In practice, that means the code is mostly about the relationship between buildings and streets: how close a building sits to the sidewalk, how much of its ground floor is glass and doors, how tall it can be, and where the parking goes. Uses are still regulated, but each zone allows the uses that suit the kind of place it is meant to be.

	Conventional zoning	Form-based code
Organising idea	Separate land uses	The physical character of a place
The map	Use districts (R-1, C-2, M)	A regulating plan of transect zones
How rules are written	Mostly text and numeric limits	Diagrams, tables and photos keyed to each zone
Main focus	What happens inside the lot	Where the building meets the street
Typical result	Uses kept apart, car-oriented sites	Mixed, walkable blocks

The Las Vegas transect

The code is organised around the rural-to-urban transect. This planning model ranks places from most natural to most urban: T1 Natural, T2 Rural, T3 Sub-Urban, T4 General Urban, T5 Urban Center and T6 Urban Core, plus special districts for uses that don't fit the scale, such as heavy industry. Downtown Las Vegas has no rural land, so the city's version starts at T3.

Each transect zone describes a type of place. Building height, lot placement and ground-floor treatment step up from T3 to T6.

Within each level there are several zones for different situations, such as a neighbourhood street, a main street or a busy corridor. Version 2.0 of the code, adopted in July 2019, lists ten:

Zone	What it is for
`T6-UC` T6 Urban Core	The highest-intensity part of downtown: a wide range of building types, active ground floors and parking in garages lined with shops.
`T6-UG` T6 Urban General	High-intensity, walkable blocks with active frontages on several streets and room for regional-scale uses and jobs.
`T5-M` T5 Maker	Medium- to high-intensity areas mixing new and reused buildings for homes, offices, shops and workspace close to transit.
`T5-C` T5 Corridor	Major arterial roads with heavy traffic, shaped so they can mature into transit corridors over time.
`T5-MS` T5 Main Street	Compact main streets with offices, services and shops on the ground floor and homes upstairs.
`T5-N` T5 Neighborhood	Compact urban housing in a range of sizes, with limited shops and services.
`T4-C` T4 Corridor	The lower-intensity version of the corridor zone, for arterials passing through smaller-scale areas.
`T4-MS` T4 Main Street	Smaller main streets with small to medium buildings and mostly active street fronts.
`T4-N` T4 Neighborhood	Established walkable neighborhoods that can add a mix of housing types at a moderate scale.
`T3-N` T3 Neighborhood	Existing neighborhoods of mostly detached homes on small to medium lots, protected as they are.

Descriptions are paraphrased from the intent statements in Section 19.09.050. Later district rezonings used further zones: the 2021 Arts District proposal listed T4 Maker (T4-M) and T6 Urban General Limited (T6-UG-L).

The regulating plan

The transect zones only take effect once they are drawn onto a map. That map is the regulating plan. In form-based codes it does the job a zoning map does in a conventional code, assigning each block or parcel a zone. Las Vegas adopts these one district at a time, which is why the code has a section for each of the 12 downtown districts, several of them still marked as placeholders.

Building types

Each zone lists the building types it allows. The code splits them into two families. House-scalebuildings are roughly 25 to 90 feet wide and include the small, medium and large house, duplexes, bungalow courts, fourplex courts, rowhouses and live/work units. Block-scale buildings fill most of a block, alone or in a row. These include courtyard buildings, flex low-, mid- and high-rise buildings, lined buildings (garages wrapped in shops or apartments) and lofts.

The names describe a building's shape, not its use. A medium house can hold an office or a restaurant if the zone allows those uses.

Frontage types

The frontage is the strip between the building face and the sidewalk, and it is where a form-based code does much of its work. Chapter 19.09 defines ten:

Shopfront: large windows and an entrance at sidewalk level, the standard main-street ground floor.
Gallery: a lightweight covered walkway along the shopfronts.
Arcade: the building's upper floors extend over the sidewalk on columns, giving shade.
Forecourt: part of the facade steps back to form a small court.
Terrace: a raised platform along the facade, useful where the ground slopes.
Stoop: steps up to an entrance, typical of rowhouses.
Dooryard: a small fenced or walled front garden.
Porch, engaged and porch, projecting: the classic house porch, set into or out from the facade.
Common yard: a deep front lawn shared visually with neighbours.

For a city that regularly tops 110°F in summer, the shading frontages, gallery and arcade, are more than decoration.

Open space types

The code also defines eight kinds of public open space so that new development produces usable places, not leftover strips of landscaping: greenway, urban park, square, plaza, pocket plaza, pocket park, community garden and playground.

Thoroughfare plans

Streets are part of the code too. Each district has a thoroughfare plan section that sets how its streets are designed, treating the street and the buildings lining it as one public space. Like the district sections, most of these were left as placeholders until each district was coded.

How a district gets coded

Adopting the chapter in 2018 did not rezone anyone's property. Each district goes through its own process, normally led by the city's long-range planning staff with Lisa Wise Consulting:

Outreach and drafting: surveys, workshops, design charrettes and neighbourhood meetings.
A General Plan Amendment changing the district's land-use designation to Form-Based Code.
A rezoning that applies transect zones to each parcel through the regulating plan.
Notice to property owners, a neighbourhood meeting and a Planning Commission hearing.
A final vote at City Council.

Fremont East took eleven months from start to council vote. Text amendments to the code itself, such as the Version 2.0 update, go through the same commission and council steps.

What it means for owners and builders

The main promise of a form-based code is predictability. If a proposal fits the building type, frontage and height rules for its zone, the outcome is largely known in advance. That should mean fewer case-by-case negotiations and a faster review. Neighbours also get a clearer idea of what can be built next door.

The code keeps the city's usual relief tools for projects that don't fit: minor modifications, waivers, variances and special use permits, plus site development plan review. Existing buildings that don't meet the new standards are covered by nonconformity rules rather than being made illegal overnight.

Adoption history in brief

Chapter 19.09 was adopted by Ordinance 6649 on October 17, 2018 and took effect for mapped properties on October 22, 2018. The Medical District pilot area was rezoned in January 2019, Fremont East in October 2019 and the Historic Westside in January 2021. It was the first form-based code adopted in Nevada, and in 2019 it won the Nevada chapter of the American Planning Association's award for Outstanding Implementation Plan. See the full timeline.

Common questions

Is the form-based code law, or just design guidance?

It is law. Chapter 19.09 is part of Title 19, the Las Vegas Unified Development Code, and where a property has been rezoned to a transect zone it replaces the old base zoning rather than sitting on top of it as guidance.

Does it apply to the Las Vegas Strip?

No. Most of the Strip lies in unincorporated Clark County, outside the City of Las Vegas, and is governed by county zoning. Chapter 19.09 is a City of Las Vegas code for downtown, and it only applies to properties the city has mapped with a form-based zone.

Which areas are covered right now?

Three downtown districts have been rezoned: the Las Vegas Medical District pilot area (2019), Fremont East (2019) and the Historic Westside (2021), more than 1,100 acres in total. A rezoning of about 131 acres in the 18b Las Vegas Arts District went through public meetings in 2021 and 2022.

Does a form-based code ban certain businesses?

It still controls use, but in a different order. Each transect zone lists the uses that fit the kind of place it is meant to be. Building type names do not restrict use either: the code itself notes that a "medium house" building can hold a restaurant or office if the zone allows it.

Where can I read the official text?

The city publishes Chapter 19.09 as a PDF and in its online Unified Development Code. For anything that affects a specific property, rely on those documents and the city's zoning atlas, not on summaries like this one.
