North Las Vegas does not allow an accessory dwelling unit by right on a standard single-family lot: in the O-L, R-E, R-EL and R-1 districts an ADU is a Special Use that needs a Planning Commission hearing under §17.20.030.F.2.c and §17.12.070.J, and the code as codified through August 5, 2026 still says so. If approved, the unit must sit on a lot of at least 6,000 sq ft, contain a kitchen and bathroom, measure between 200 sq ft and the lesser of 50% of the house or 800 sq ft (400 sq ft for a tiny house), keep 3-ft side and rear setbacks and 12 ft of height in R-1, and stand at least 300 ft from any other ADU. A no-kitchen guest house/casita on the same 6,000 sq ft lot is permitted by right but is capped at the lesser of 25% of the house or 800 sq ft and may not be rented. Budget $1,000 for the Special Use Permit, roughly $1,200-$1,500 for a valuation-based building permit with plan check (Table 3-A, §15.72.230), $1,730 for a casita sewer connection and $0.36 per sq ft park fee. Nevada AB 396 required a compliant ADU ordinance by July 1, 2026; the city has said publicly that its existing code complies and had adopted no amendment by August 5, 2026 — confirm your parcel's path with Planning and Zoning at (702) 633-1537 before you pay for drawings.
Zoning & Size Requirements [1][2][3][4][5][6]
Sometimes — North Las Vegas allows ADUs, but not by right on a typical lot. The North Las Vegas Zoning Ordinance, as codified through August 5, 2026, makes an accessory dwelling unit a Special Use in the O-L, R-E, R-EL and R-1 districts — a Planning Commission hearing under §17.12.070.J, not a counter permit — on a lot of at least 6,000 sq ft, capped at the lesser of 50% of the house or 800 sq ft and at least 300 ft from any other ADU (§17.20.030.F.2.c). ADUs are permitted without a hearing only in PUD/PID, MUD, PCD and R-A/DC districts, subject to each development's own plans. Nevada AB 396 required a compliant ordinance by July 1, 2026; the city has said its existing code complies and had adopted no amendment by August 5, 2026 — confirm your parcel's path with Planning and Zoning at (702) 633-1537.
| Allowed Zones | Special Use ("S") in the O-L, R-E, R-EL and R-1 single-family districts — a Special Use Permit and Planning Commission hearing, not a by-right permit (Table 17.20-3; §17.20.030.C.1.c; §17.12.070.J). Permitted ("P") only in PUD/PID, MUD, PCD and R-A/DC, and there "subject to approval pursuant to the individual review procedure" and the development's own plans (§17.20.030.F.2.b). Prohibited in R-CL, R-2, R-3 and R-4. A no-kitchen guest house/casita is "P" in O-L, R-E, R-EL, R-1 and R-CL. |
| Max Size (Detached) | 800 sq ft or 50% of the principal dwelling's gross floor area, whichever is less, with a 200 sq ft minimum; a tiny-house ADU may not exceed 400 sq ft (§17.20.030.F.2.c.iv). A no-kitchen guest house/casita is capped at the lesser of 25% of the house's living area or 800 sq ft on a 6,000 sq ft lot (§17.20.030.D.2.a.iii). Other accessory buildings: 600 sq ft, or 1,200 sq ft on a 15,000 sq ft lot; all accessory buildings together may cover at most 25% of the rear yard (§17.20.030.D.2.a–b). |
| Max Size (Attached) | Same cap — the code says nothing prevents an ADU "being located within or inside a principal dwelling structure" and applies the same 200 sq ft floor and lesser-of-50%-or-800 sq ft ceiling (§17.20.030.F.2.b.i and F.2.c.iv). A garage conversion is not a route to an ADU: it is a Conditional Use, needs findings about other conversions within 300 ft, and "shall not be used to provide the house with a second kitchen or to allow for a second dwelling unit" (§17.20.030.F.6.a–b). |
| Max Size (JADU) | Not a category in Nevada — North Las Vegas has no junior ADU designation. The nearest thing is a tiny-house ADU of 200 to 400 sq ft on a permanent foundation, which the code folds into the ADU definition (§17.32.030 "Dwelling Unit, Accessory" and "Tiny House"; §17.20.030.F.2.c.iv). |
| Max Height | 12 ft for accessory structures in R-1, R-EL, R-CL and R-2; 16 ft in R-3 and R-4; 28 ft in R-E and O-L (Table 17.24.010-2, §17.24.010.A.2). The house itself may go to 35 ft in R-1, so the 12-ft cap is what shapes a detached ADU there. An accessory structure may never exceed the height of the principal structure (§17.20.030.B.1.j). |
| Max Units | One ADU per lot (§17.20.030.F.2.c.vi), and the ADU does not count toward the district's maximum density (F.2.c.viii). The code also imposes a spacing rule found nowhere else in the Valley: "no accessory dwelling unit shall be located within three hundred (300) feet of another accessory dwelling unit" (§17.20.030.F.2.c.v) — a neighbour's permitted ADU can disqualify your lot. |
Setback Requirements [1][2][3][4][5][6]
North Las Vegas requires a rear setback of about 3 ft for a detached ADU, and parking requirements vary by unit size or location. Owner-occupancy is not required — you can rent it out without living on the property.
| Rear Setback | 3 ft for an accessory structure in every residential district — O-L, R-E, R-EL, R-1, R-CL, R-2, R-3 and R-4 (Table 17.24.010-2). The principal dwelling in R-1 must keep 15 ft, so the accessory allowance is a real gain. The binding limit is usually coverage: all accessory buildings, detached garages and casitas together may not occupy more than 25% of the rear yard (§17.20.030.D.2.a–b). |
| Side Setback | 3 ft on an interior side for an accessory structure in O-L, R-E, R-EL, R-1, R-2, R-3 and R-4; 5 ft in R-CL. Corner side: 10 ft in R-E, R-EL, R-1, R-CL, R-2, R-3 and R-4; 20 ft in O-L (Table 17.24.010-2). A detached structure must also keep at least 5 ft of separation from the main house (§17.20.030.B.1.p and D.1.b). |
| Front Setback | 20 ft for an accessory structure in R-E, R-EL, R-1, R-2, R-3 and R-4; 15 ft in R-CL; 30 ft in O-L (Table 17.24.010-2). §17.20.030.B.1.o and D.1.a separately require a detached structure to meet the main building's front setback (15 ft in R-1), and nothing may be built between the front lot line and the front setback line (§17.20.030.B.1.k) — in practice the ADU goes behind the house. |
| Parking Required | At least one off-street space for the ADU in addition to the principal dwelling's required parking, and "in no instance shall more than two" be provided (§17.20.030.F.2.c.vii). Nevada AB 396 caps what a covered city may require at one space, so one space is the ceiling the city can impose — a second space is optional, not a condition. |
| Owner Occupancy | Not required — §17.20.030.F.2 contains no owner-occupancy clause. The code does require that the ADU "shall not be sold apart from the principal dwelling unit" and bars home occupations inside it (§17.20.030.F.2.c.x–xi). A guest house/casita is different: by definition it "does not include a structure that is available on a rental basis" (§17.32.030), so a unit you intend to rent must be permitted as an ADU. |
| Min Lot Size | 6,000 sq ft 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 equals the R-1 district's own minimum lot (Table 17.24.010-1), so a standard R-1 tract lot qualifies; R-CL compact lots (3,600 sq ft minimum) are not eligible for an ADU at all, though they may add a no-kitchen casita. |
Permit Process & Fees [7][8][9][10][11][12]
An ADU permit in North Las Vegas goes through a standard permit review. Review time: not published. The Special Use Permit adds a Planning Commission hearing cycle (decision due within 30 days of the first hearing, final on day eight unless appealed, §17.12.070.J) before building plan review starts — ask Planning and Zoning at (702) 633-1537 for current turnaround. Permit fees: Special Use Permit $1,000 ($500 + $500 notification; Land Development Application Manual). Building permit by valuation, Table 3-A: $620 for the first $100,000 + $3.30 per $1,000, plus 65% plan check, 10% zoning review, $75 admin and 3% recording (§15.72.230) — about $1,470 on a $150,000 unit.
| Approval Process | Special Use Permit first (§17.12.070.J): application through the Planning and Zoning Division, public notice, a Planning Commission public hearing with the owner present, a decision within 30 days of the first hearing, final on the eighth day unless appealed to City Council. Then a building permit through the Development Services Center / Permit Application Center, 2250 Las Vegas Blvd. North, (702) 633-1536 (permits) or (702) 633-1537 (planning). In PUD/PID, MUD and PCD districts the ADU is permitted but goes through the development's individual review procedure and must fit its approved plans (§17.20.030.F.2.b). A no-kitchen casita needs only the building permit. |
| Review Timeline | Not published. The Special Use Permit adds a Planning Commission hearing cycle (decision due within 30 days of the first hearing, final on day eight unless appealed, §17.12.070.J) before building plan review starts — ask Planning and Zoning at (702) 633-1537 for current turnaround. |
| Permit Fees | Special Use Permit $1,000 ($500 + $500 notification; Land Development Application Manual). Building permit by valuation, Table 3-A: $620 for the first $100,000 + $3.30 per $1,000, plus 65% plan check, 10% zoning review, $75 admin and 3% recording (§15.72.230) — about $1,470 on a $150,000 unit. |
| Impact Fees | Park impact fee $0.36 per sq ft of residential construction and a Clark County Transportation Tax of $1,000 per residential unit (Permit Application Center fee page; whether the tax is assessed on an ADU is not stated — ask at intake). Sewer main connection fee: "Guest home (casita)" 1.00 ERU, $1,730 per dwelling unit in the city's Water Reclamation Facility service area; in the Clark County Water Reclamation District area the District's connection fee applies plus a $500 city administrative fee (§13.24.070.A). Wastewater main construction (frontage) fees can apply where no main serves the lot (§13.24.070.B). |
| Plan Check | Plan review through the Development Services Center (single point of entry, concurrent reviews). Fee: 65% of the building permit fee for building plan check plus 10% for zoning review, paid at submittal; revisions $80/hr; re-inspection $100; same-day inspection $100 (§15.72.230.B; Permit Application Center). Valuation is set by the Building Official from Table 3-E or the contract price (§15.72.170.B). Mobile homes, RVs and travel trailers may not serve as ADUs (§17.20.030.F.2.c.iii); an accessory structure may not sit in a utility easement or go up before the house (§17.20.030.B.1.l–m). |
| Pre-Approved Plans | None. The Permit Application Center's forms and submittal guides (Single-Family Residential, Residential Plot Plan and the rest) include no pre-approved or stock ADU plan set. |

Recent Law Changes
What's Changed Recently
- Code check September 20, 2026: the North Las Vegas Municipal Code on Municode, codified through ordinances adopted on or before August 5, 2026 (Supp. No. 146, Update 1, posted August 21, 2026), still lists ADUs as a Special Use in O-L, R-E, R-EL and R-1 with the 6,000 sq ft lot, 300-ft spacing, lesser-of-50%-or-800 sq ft and one-to-two-space parking rules. §17.20.030's ordinance history ends at Ord. No. 3255 (December 17, 2025, ZOA-01-2025), a general zoning text amendment; no 2026 ordinance amending the ADU provisions appears in the code's comparative table or in Municode's ordinance bank
- Nevada AB 396 (Chapter 365, Statutes of Nevada 2025) required every city over 60,000 — North Las Vegas included — to adopt an ordinance authorising ADUs on residential property by July 1, 2026, failing which ADUs are authorised on any residentially zoned parcel without restriction; a compliant ordinance may not require more than one parking space or prohibit kitchens, and HOAs may not prohibit ADUs outright. In June 2026 city staff told FOX5 Las Vegas that the existing code already complies. That position has not been tested in any document this research could read; the Special Use Permit, the 300-ft spacing rule and the 6,000 sq ft lot minimum remain in the code as written
- Size floor corrected: the current code sets the ADU minimum at 200 sq ft (not the 400 sq ft this page stated on September 1, 2026, taken from a 2017-vintage mirror of the code) and adds a 400 sq ft cap for a tiny-house ADU; the definition of "Dwelling Unit, Accessory" now expressly includes a tiny house (§17.20.030.F.2.c.iv; §17.32.030). The mirror's "one accessory building permit per lot" sentence is no longer in §17.20.030.D.2
- Ord. No. 3270 (February 18, 2026, ZOA-02-2025) amended §17.20.010–.020, §17.24.010.B and §17.32.030 to allow mixed-use with a residential component on commercial land; it did not touch the ADU standards or the residential setback and height tables
- Ordinance 3127 (June 15, 2022) created the short-term rental Conditional Use Permit regime — 660-ft separation between short-term rentals and 2,500 ft from resort hotels — and remains the rule on the city's Short-Term Rentals page (read September 20, 2026)
Tips for Building an ADU in North Las Vegas
- Ask Planning and Zoning one question before anything else: "Does my lot need a Special Use Permit for an ADU, or is the city applying AB 396 directly?" (702) 633-1537. The code says Special Use Permit; the city has said publicly that its code complies with the state law; get the answer for your parcel in writing
- Know which thing you are building. A guest house/casita has no kitchen, is permitted by right in O-L, R-E, R-EL, R-1 and R-CL, and cannot legally be rented. An accessory dwelling unit has a kitchen, can be rented, and needs the Special Use Permit in those districts
- Check the 300-ft rule first. It is measured ADU to ADU, and in an established neighbourhood your eligibility can already have been decided by a permit a neighbour pulled years ago
- If you live in a PUD (much of the master-planned north of the city), the code marks ADUs "P" — but subject to the development's own review procedure, plans and agreements, so the PUD plan and your CC&Rs decide, not Table 17.20-3. AB 396 bars an HOA from prohibiting ADUs outright
- Design to 12 ft in R-1 (and R-EL, R-CL, R-2). The accessory-structure height limit is 12 ft against 35 ft for the house — a single-storey unit with a low pitch, not a lofted one
- The 3-ft side and rear setbacks are generous for the Valley, but the 25%-of-rear-yard coverage cap — counted together with the garage and any shed — is what sizes the building on a 6,000 sq ft lot. Measure the rear yard before you draw
- Do not plan a garage conversion as your ADU: it is a Conditional Use and the code bars the converted space from adding a second kitchen or a second dwelling unit (§17.20.030.F.6.b)
- Fee worked example (Table 3-A, §15.72.230): a unit valued at $150,000 → permit $785, plan check $510, zoning review $79, admin $75, recording $24, about $1,470 in all; at $100,000 about $1,180. Sewer connection $1,730 and the park impact fee ($216 for 600 sq ft) come on top; ask at intake whether the $1,000 Clark County Transportation Tax applies to an ADU
- Cost basis: Las Vegas Valley 2026 guides read September 20, 2026 — detached $180-$300 per sq ft ($90,000-$180,000 for 400-700 sq ft) and prefab $140-$250 per sq ft installed (Nevada Real Estate Group, July 9, 2026); $200-$350 per sq ft all-in (IRES, 2026); $140-$280 per sq ft (ADU Wizard, 2026). North Las Vegas caps an ADU at 800 sq ft, so the top of the range sits below Henderson's. Rents are HUD FY2027 Small Area FMRs for ZIPs 89030-89086 ($1,340-$1,730 one-bedroom; 89085 runs higher)
- Cost basis (2026-09-20 re-verification): short term allowed: Only with a Conditional Use Permit ($100 application fee) under Ordinance 3127 (June 2022), approved before the business licence: 660-ft separation from other existing or proposed short-term rentals, 2,500 ft from resort hotels, a notarised HOA authorisation letter, a site plan showing noise-monitoring equipment, a security plan and Transient Lodging Tax (city Short-Term Rentals page, read 2026-09-20). The code says nothing specific about short-term rental inside an ADU; a no-kitchen casita cannot be rented at all (§17.32.030).
