Accessory Dwelling Unit (ADU) Permit in North Las Vegas, Nevada
Required for construction of an accessory dwelling unit (ADU, also called guest house/casita) on a residential property in the City of North Las Vegas. Local dimensional standards are codified in NLV Municipal Code Title 17 (Zoning), §17.20.030.F.2 — Accessory Dwelling Units (Supp. 144). In the single-family residential districts (O-L, R-E, R-EL, R-1) an ADU requires a special use permit and is limited to lots ≥6,000 sq ft; the ADU must be 200–800 sq ft and may not exceed 50% of the principal dwelling's gross floor area (whichever is less). NLV (population 60,000+) is also subject to NRS 278.257 (eff. July 1, 2026), which mandates NLV authorize ADUs on single-family residential lots and prohibits any local ordinance from barring the owner from renting the ADU as long-term housing (transient/short-term lodging may still be prohibited); local conditions more restrictive than that statute are superseded as of July 1, 2026. Governed by the 2024 IRC with Southern Nevada amendments.

When you need this permit
- In O-L, R-E, R-EL, and R-1 districts an ADU is allowed only by special use review and only on a lot of at least 6,000 sq ft whose principal use is a single-family dwelling (NLVMC §17.20.030.F.2.c)
- ADU gross floor area: minimum 200 sq ft; maximum is the lesser of 50% of the principal dwelling's gross floor area or 800 sq ft; a tiny house may not exceed 400 sq ft (NLVMC §17.20.030.F.2.c.iv)
- ADU must contain its own kitchen and restroom facilities (NLVMC §17.20.030.F.2.c.ii)
- No more than one ADU per lot, and no ADU may be located within 300 ft of another ADU in these districts (NLVMC §17.20.030.F.2.c.v–vi)
- At least one off-street parking space in addition to that required for the principal use, and no more than two off-street spaces for the ADU (NLVMC §17.20.030.F.2.c.vii)
- Mobile homes, recreational vehicles, and travel trailers may not be used as ADUs; the ADU may not be sold apart from the principal dwelling; home occupations are prohibited in an ADU (NLVMC §17.20.030.F.2.c.iii, x, xi)
- A 'Guest House/Casita' is separately permitted (P) by right in the R-E, R-EL, R-1, and R-CL districts per Table 17.20-3; ADUs (with full kitchen) are 'S' (special use) in those single-family districts and 'P' in PUD/PID, MUD, and PCD districts
- NRS 278.257 (eff. July 1, 2026) prohibits: prohibiting separate kitchen facilities, requiring >1 extra parking space (where existing + street parking is adequate), requiring street improvements except for construction-disturbance repair or public health/safety, setbacks more restrictive than the primary residence, or barring the ADU from long-term rental housing — these supersede any more-restrictive Title 17 condition as of that date (NRS 278.257(2), confirmed via direct statute text 2026-07-17). NOTE: the statute contains no owner-occupancy provision, and NLV's own Title 17 §17.20.030.F.2 ADU standards do not impose an owner-occupancy condition either — an earlier version of this entry incorrectly attributed an owner-occupancy bar to NRS 278.257; that claim has been removed as unsupported by the statute's text
- Submit Building Permit Application at Permit Application Center
- Plans must comply with 2024 IRC with Southern Nevada amendments
- Automatic fire sprinkler system required (permits issued on or after January 5, 2026 per Ord. 3256) — NOTE: NRS 278.257 Sec. 3(b) exempts ADUs from commercial fire-sprinkler codes; the NLV residential sprinkler requirement under IRC/Ord. 3256 applies to residential units; confirm with Building Safety
- Separate sub-permits required for electrical, plumbing, and mechanical
- Plot plan showing ADU relative to primary dwelling and property lines required

Tips
- Local ADU dimensional standards are in NLV Municipal Code §17.20.030.F.2 (Supp. 144): in O-L/R-E/R-EL/R-1 districts an ADU needs a special use permit, a lot of at least 6,000 sq ft, and is capped at the lesser of 50% of the principal dwelling's gross floor area or 800 sq ft (min 200 sq ft; tiny house max 400 sq ft).
- In these single-family districts no ADU may be within 300 ft of another ADU, and only one ADU is allowed per lot (NLVMC §17.20.030.F.2.c.v–vi).
- NRS 278.257 (eff. July 1, 2026) mandates NLV authorize ADUs on single-family residential lots — NLV cannot bar long-term rental of the ADU, cannot prohibit a separate kitchen, cannot require more than one extra parking space where existing plus street parking is adequate, and cannot impose setbacks more restrictive than the primary residence; conditions in Title 17 more restrictive than the statute are superseded as of that date. The statute does not address owner-occupancy, and NLV's own ADU standards impose no owner-occupancy requirement either (verified against statute and Title 17 text 2026-07-17).
- A 'Guest House/Casita' (accessory living quarters) is permitted by right in the R-E, R-EL, R-1, and R-CL districts per Table 17.20-3 — a full ADU (with kitchen) is the special-use category.
- Automatic fire sprinkler systems are required for permits issued on or after January 5, 2026 (Ord. 3256). NRS 278.257 Sec. 3(b) provides ADUs are not required to meet codes for commercial buildings (including commercial sprinkler codes) — verify applicability of residential sprinkler requirement with Building Safety.
- The Clark County Transportation Tax ($1,000/unit) applies to each new dwelling unit including ADUs.
