North Las Vegas is the Las Vegas Valley city where the rules and the state law have not visibly met yet. Nevada's AB 396 (Chapter 365, Statutes of Nevada 2025) covers every city over 60,000 people — North Las Vegas at roughly 296,653 is squarely inside it — and required a compliant ADU ordinance by July 1, 2026, with a hard default: if a covered city did not adopt one, ADUs are authorised on any residentially zoned parcel without restriction. Meanwhile the North Las Vegas Zoning Ordinance as published still says an accessory dwelling unit in the O-L, R-E, R-EL and R-1 districts is a Special Use — a hearing, not a counter application — capped at the lesser of 50% of the house or 800 sq ft, on a lot of at least 6,000 sq ft, and not within 300 feet of another ADU. Several of those provisions look squarely at odds with AB 396. Nothing in a City of North Las Vegas source that could be reached confirms whether the city adopted a compliance ordinance before the deadline, and the official code host was unreachable. Before you spend money on drawings, call Planning and Zoning at (702) 633-1537 and ask one question: does my lot need a Special Use Permit for an ADU today, or does AB 396 govern?
Zoning & Size Requirements [1][2][3][4]
Sometimes — North Las Vegas allows ADUs, but not by right on a typical lot. As published, the North Las Vegas Zoning Ordinance makes an accessory dwelling unit a Special Use in the O-L, R-E, R-EL and R-1 districts — a Planning Commission hearing, not a counter application — with a 6,000 sq ft minimum lot, a lesser-of-50%-or-800 sq ft size cap and a 300-foot separation from any other ADU (§17.20.030.F.2.c). Nevada AB 396 binds North Las Vegas as a city over 60,000 and required a compliant ordinance by July 1, 2026, failing which ADUs are authorised on any residentially zoned parcel without restriction. No City of North Las Vegas source reachable in this research confirms whether that ordinance was adopted — confirm with Planning and Zoning at (702) 633-1537.
| Allowed Zones | Accessory dwelling units carry an "S" — special use — in the O-L, R-E, R-EL and R-1 residential districts and in several business districts, and a "P" only in PUD/PID, MUD and PCD districts (North Las Vegas Zoning Ordinance Table 17.20-3, Permitted Accessory Use Table). A Guest House/Casita, by contrast, is a "P" — permitted by right — in O-L, R-E, R-EL, R-1 and R-CL. The difference is the kitchen: §17.32.030 defines a Guest House/Casita as living quarters "that does not have kitchen facilities... used for guests or servants employed on the premises," and adds that "the term does not include a structure that is available on a rental basis." AB 396 bars a covered city from prohibiting kitchens in an ADU, so this split is exactly what the state law was written to end — confirm the current position with Planning and Zoning at (702) 633-1537 |
| Max Size (Detached) | Under the published code: at least 400 sq ft and no more than the lesser of 50% of the principal dwelling's gross floor area or 800 sq ft (§17.20.030.F.2.c.iv). A guest house/casita without a kitchen is separately capped at the lesser of 25% of the principal dwelling's living area or 800 sq ft, on a lot of at least 6,000 sq ft (§17.20.030.D.2.a.iii). Ordinary accessory buildings are held to 600 sq ft, or 1,200 sq ft on a lot of 15,000 sq ft or more, and no accessory building may occupy more than 25% of the rear yard (§17.20.030.D.2.a and D.2.c) |
| Max Size (Attached) | Same rule — the code contemplates an ADU "being located within or inside a principal dwelling structure" and applies the same 400 sq ft floor and lesser-of-50%-or-800 sq ft cap (§17.20.030.F.2.b.i and F.2.c.iv). A garage conversion is treated separately and more harshly: it is a Conditional Use, and §17.20.030.F.6.b says the converted living area "shall not be used to provide the house with a second kitchen or to allow for a second dwelling unit" |
| Max Size (JADU) | Not a category in Nevada — North Las Vegas has no junior ADU designation |
| Max Height | 12 feet for accessory structures in the R-1 and R-EL districts, 28 feet in R-E and O-L, and 16 feet in R-3 and R-4 (Table 17.24.010-2, Building Setback and Height Requirements for Residential Zone Districts). The 12-foot cap in R-1 — the city's main single-family district — is the constraint most likely to reshape an ADU design, since the house itself may go to 35 feet. §17.20.030.B.1.j separately provides that an accessory structure shall not exceed the height of the principal structure |
| Max Units | One ADU per lot (§17.20.030.F.2.c.vi), and one accessory building permit per lot (§17.20.030.D.2.b). The published code adds a spacing rule with no equivalent anywhere else in the Valley: "In order to limit increases in density within the applicable zoning districts, no accessory dwelling unit shall be located within three hundred (300) feet of another accessory dwelling unit" (§17.20.030.F.2.c.v). If that survived AB 396, your neighbour's casita can disqualify your lot — check it before anything else |
Setback Requirements [1][2][3][4]
North Las Vegas requires a rear setback of about 3 ft for a detached ADU, and one off-street parking space is required. Owner-occupancy is set by local rules (confirm with the city).
| Rear Setback | 3 feet for an accessory structure in R-1, R-E, R-EL, R-CL, R-2, R-3 and R-4, and in O-L (Table 17.24.010-2). The principal dwelling in R-1 must keep 15 feet, so the accessory allowance is a real gain. Note the separate rear-yard coverage rule: all accessory buildings, detached garages and casitas together may not occupy more than 25% of the rear yard (§17.20.030.D.2.c) |
| Side Setback | 3 feet on an interior side for an accessory structure in every residential district; 10 feet on a corner side in R-1, R-E, R-EL, R-CL, R-2, R-3 and R-4, and 20 feet in O-L (Table 17.24.010-2). A detached accessory structure must also keep a minimum five feet of separation from the main house (§17.20.030.B.1.p and D.1.b) |
| Front Setback | 20 feet for an accessory structure in R-1, R-E, R-EL, R-2, R-3 and R-4; 15 feet in R-CL; 30 feet in O-L (Table 17.24.010-2). Read that alongside §17.20.030.D.1.a, which says a detached structure "shall meet the setback requirements of the main building for the front yard area" — in R-1 the main dwelling's front setback is 15 feet, so the two provisions do not obviously agree. Ask Planning and Zoning at (702) 633-1537 which they apply. Nothing may be stored or constructed between the front lot line and the front setback line (§17.20.030.B.1.k) |
| Parking Required | The published code requires "at least one off-street parking space... in addition to the required off-street parking serving the principal use, but in no instance shall more than two off-street parking spaces be provided" (§17.20.030.F.2.c.vii). AB 396 bars a covered local ordinance from requiring more than one space for an ADU, so one space is the ceiling the state allows North Las Vegas to impose — if a plan reviewer asks for two, cite AB 396 |
| Owner Occupancy | No owner-occupancy requirement appears in §17.20.030. What the code does impose is that an ADU "shall not be sold apart from the principal dwelling unit" and that home occupations are prohibited inside an ADU (§17.20.030.F.2.c.x and xi). Separately, a guest house/casita by definition "does not include a structure that is available on a rental basis" (§17.32.030) — so if you want to rent, you need the ADU classification, not the casita one |
| Min Lot Size | 6,000 sq ft minimum for an ADU in O-L, R-E, R-EL and R-1, and the principal use must be a single-family dwelling (§17.20.030.F.2.c.i). That happens to equal the R-1 district's own minimum lot area, so a standard R-1 tract lot qualifies; R-CL compact lots at 3,600 sq ft do not, and R-CL is not among the districts where ADUs are listed at all |
Permit Process & Fees [5][6]
An ADU permit in North Las Vegas goes through a standard permit review. Confirm with North Las Vegas Planning and Zoning at (702) 633-1537 — no published ADU review timeline was found in a city source. A Special Use Permit adds a Planning Commission hearing cycle to whatever the building permit takes. Permit fees: Confirm with North Las Vegas Planning and Zoning at (702) 633-1537 — the Planning and Zoning fee schedule is not published on the city's ADU-relevant pages, and the city's official code and fee host could not be reached from this research session. Budget for a Special Use Permit application fee on top of valuation-based building permit fees if the SUP requirement still applies to your lot.
| Approval Process | Under the published code, a Special Use Permit — Planning Commission review under §17.12.070, not an over-the-counter approval — for an ADU in O-L, R-E, R-EL or R-1, followed by a building permit. A guest house/casita with no kitchen is permitted by right and needs only a building permit. Whether the Special Use Permit requirement still stands after AB 396's July 1, 2026 deadline is the open question on this page: the statute's default is that ADUs are authorised on any residentially zoned parcel without restriction where a covered city failed to adopt a compliant ordinance. Ask North Las Vegas Planning and Zoning at (702) 633-1537, 2250 Las Vegas Blvd. North, Suite 114, before you assume either way |
| Review Timeline | Confirm with North Las Vegas Planning and Zoning at (702) 633-1537 — no published ADU review timeline was found in a city source. A Special Use Permit adds a Planning Commission hearing cycle to whatever the building permit takes |
| Permit Fees | Confirm with North Las Vegas Planning and Zoning at (702) 633-1537 — the Planning and Zoning fee schedule is not published on the city's ADU-relevant pages, and the city's official code and fee host could not be reached from this research session. Budget for a Special Use Permit application fee on top of valuation-based building permit fees if the SUP requirement still applies to your lot |
| Impact Fees | Confirm with North Las Vegas Land Development — no ADU-specific impact fee schedule was found in a city source |
| Plan Check | Standard residential plan review through the city's Development Services Center, which the city describes as a single point of entry for construction review and permitting with concurrent reviews where possible. Mobile homes, recreational vehicles and travel trailers may not be used as accessory dwelling units (§17.20.030.F.2.c.iii), and an accessory structure may not be built in a utility easement or before the principal structure exists (§17.20.030.B.1.l and m) |
| Pre-Approved Plans | No city pre-approved ADU plan library was found in a North Las Vegas source |

Rental Income Potential [8][9]
A 2-bedroom ADU in North Las Vegas rents for around $1,400-$1,800/mo, an estimated 6-9% annual return.
| Avg Rent (1 Bedroom) | $1,150-$1,450/mo |
| Avg Rent (2 Bedroom) | $1,400-$1,800/mo |
| Short-Term Rental | Only with a Conditional Use Permit, and the separation rules make most lots ineligible. North Las Vegas adopted Ordinance 3127 in June 2022 to allow short-term rentals with an approved Conditional Use Permit, which must be in hand before a business licence application. The CUP requires a 660-foot separation from other existing or proposed short-term rentals, a 2,500-foot separation from resort hotels, a notarised HOA authorisation letter, a site plan showing noise monitoring equipment and a security plan, plus Transient Lodging Tax. A no-kitchen guest house/casita cannot be rented at all — the definition in §17.32.030 excludes any structure "available on a rental basis" |
| Est. Annual ROI | 6-9% annual return |

Recent Law Changes
What's Changed Recently
- Nevada AB 396 (Chapter 365, Statutes of Nevada 2025) requires every county over 100,000 (Clark and Washoe) and every city over 60,000 — Las Vegas, Henderson, North Las Vegas, Reno and Sparks — to adopt an ordinance authorising accessory dwelling units on residential property. The ADU provisions took effect July 1, 2026, and if a covered local government did not adopt a compliant ordinance by that date, ADUs are authorised on any residentially zoned parcel without restriction. A compliant ordinance may not require more than one parking space, may not prohibit kitchens, and HOAs may not prohibit ADUs outright
- OPEN QUESTION as of September 1, 2026: no City of North Las Vegas source reachable from this research confirms adoption of an AB 396 compliance ordinance. Reno adopted first on October 8, 2025; the City of Las Vegas adopted Ordinance No. 6963 (Bill 2026-24) on July 1, 2026; Henderson concluded its existing standards already complied. North Las Vegas's position is unverified — confirm with Planning and Zoning at (702) 633-1537
- The North Las Vegas ADU provisions relied on here, §17.20.030, carry an ordinance history ending at Ord. No. 2850, § 1, adopted 12-20-2017 (earlier: Ord. No. 2591, 6-15-2011 eff. 10-1-2011; Ord. No. 2706, 2-18-2015; Ord. No. 2809, 5-17-2017). Any 2026 amendment would post-date every version that could be read
- Ordinance 3127 (June 2022) created the city's short-term rental Conditional Use Permit regime, with 660-foot separation between short-term rentals and 2,500 feet from resort hotels
- STALE-SOURCE WARNING: the City's official code is hosted on Municode (library.municode.com/nv/north_las_vegas), which refused connections from this session behind a Cloudflare block, as did the city's PrimeGov agenda portal and leg.state.nv.us. The Title 17 text quoted here comes from a third-party mirror that publishes no "current through" date and whose §17.20.030 stops at the 2017 amendment. Every widely circulated copy of North Las Vegas's ADU rules — mirrors, zoning-data sites and contractor blogs alike — is repeating that same pre-AB 396 text. Treat the 300-foot ADU separation rule, the Special Use Permit requirement and the two-space parking language as provisions the state law may already have overridden
Tips for Building an ADU in North Las Vegas
- Ask the city one question first: "Does my lot still need a Special Use Permit for an ADU, or has AB 396 taken over?" Planning and Zoning, (702) 633-1537. The answer changes the cost of your project by thousands and the timeline by months
- Know which thing you are building. A guest house/casita has no kitchen and cannot legally be rented; an accessory dwelling unit has a kitchen and can. In North Las Vegas the code puts them in different columns of the same table, with different approval paths
- Check the 300-foot rule early if the city says it still applies. It is measured ADU to ADU, not lot to lot, and in an established neighbourhood it can be decided by a permit your neighbour pulled years ago
- Design to 12 feet in R-1. The accessory-structure height limit in the city's main single-family district is 12 feet, well under the 35 feet the house itself gets — a pitched-roof one-storey unit, not a lofted one
- The 3-foot side and rear setbacks are genuinely generous for the Valley, but the 25%-of-rear-yard coverage cap is the one that actually sizes the building on a standard 6,000 sq ft lot. Measure the rear yard before you draw
- Do not count on a garage conversion. It is a Conditional Use in North Las Vegas, it requires findings about other conversions within 300 feet, and the code expressly bars the converted space from adding a second kitchen or a second dwelling unit
- If short-term rental is the plan, check the 660-foot separation from other registered STRs and the notarised HOA letter requirement before anything else — those two knock out most applicants
- AB 396 caps ADU parking at one space. If a reviewer quotes the code's "no more than two off-street parking spaces" language back at you, that is a ceiling on the city, not a requirement on you

Frequently Asked Questions
Can I build an ADU in North Las Vegas?
Sometimes, but not by right. As published, the North Las Vegas Zoning Ordinance makes an accessory dwelling unit a Special Use in the O-L, R-E, R-EL and R-1 districts — a Planning Commission hearing, not a counter application — with a 6,000 sq ft minimum lot, a lesser-of-50%-or-800 sq ft size cap and a 300-foot separation from any other ADU (§17.20.030.F.2.c). Nevada AB 396 binds North Las Vegas as a city over 60,000 and required a compliant ordinance by July 1, 2026, failing which ADUs are authorised on any residentially zoned parcel without restriction. No City of North Las Vegas source reachable in this research confirms whether that ordinance was adopted — confirm with Planning and Zoning at (702) 633-1537. Zoning: Accessory dwelling units carry an "S" — special use — in the O-L, R-E, R-EL and R-1 residential districts and in several business districts, and a "P" only in PUD/PID, MUD and PCD districts (North Las Vegas Zoning Ordinance Table 17.20-3, Permitted Accessory Use Table). A Guest House/Casita, by contrast, is a "P" — permitted by right — in O-L, R-E, R-EL, R-1 and R-CL. The difference is the kitchen: §17.32.030 defines a Guest House/Casita as living quarters "that does not have kitchen facilities... used for guests or servants employed on the premises," and adds that "the term does not include a structure that is available on a rental basis." AB 396 bars a covered city from prohibiting kitchens in an ADU, so this split is exactly what the state law was written to end — confirm the current position with Planning and Zoning at (702) 633-1537. The maximum size for a detached ADU is Under the published code: at least 400 sq ft and no more than the lesser of 50% of the principal dwelling's gross floor area or 800 sq ft (§17.20.030.F.2.c.iv). A guest house/casita without a kitchen is separately capped at the lesser of 25% of the principal dwelling's living area or 800 sq ft, on a lot of at least 6,000 sq ft (§17.20.030.D.2.a.iii). Ordinary accessory buildings are held to 600 sq ft, or 1,200 sq ft on a lot of 15,000 sq ft or more, and no accessory building may occupy more than 25% of the rear yard (§17.20.030.D.2.a and D.2.c). Owner-occupancy: No owner-occupancy requirement appears in §17.20.030. What the code does impose is that an ADU "shall not be sold apart from the principal dwelling unit" and that home occupations are prohibited inside an ADU (§17.20.030.F.2.c.x and xi). Separately, a guest house/casita by definition "does not include a structure that is available on a rental basis" (§17.32.030) — so if you want to rent, you need the ADU classification, not the casita one.
How much does an ADU cost in North Las Vegas?
ADU construction in North Las Vegas typically costs $130,000-$250,000. Garage conversions run $60,000-$140,000, and prefab ADUs cost $90,000-$200,000.
How much can I rent an ADU for in North Las Vegas?

Do I need parking for an ADU in North Las Vegas?
The published code requires "at least one off-street parking space... in addition to the required off-street parking serving the principal use, but in no instance shall more than two off-street parking spaces be provided" (§17.20.030.F.2.c.vii). AB 396 bars a covered local ordinance from requiring more than one space for an ADU, so one space is the ceiling the state allows North Las Vegas to impose — if a plan reviewer asks for two, cite AB 396. Check with North Las Vegas planning department for the latest Nevada ADU parking rules, as many states have relaxed requirements in recent years.
How long does it take to get an ADU permit in North Las Vegas?
North Las Vegas does not publish a standard ADU review timeline — confirm with North Las Vegas Planning and Zoning at (702) 633-1537 — no published ADU review timeline was found in a city source. A Special Use Permit adds a Planning Commission hearing cycle to whatever the building permit takes. Permit fees: Confirm with North Las Vegas Planning and Zoning at (702) 633-1537 — the Planning and Zoning fee schedule is not published on the city's ADU-relevant pages, and the city's official code and fee host could not be reached from this research session. Budget for a Special Use Permit application fee on top of valuation-based building permit fees if the SUP requirement still applies to your lot.
