Reno adopted its first comprehensive ADU ordinance on October 8, 2025, implementing Nevada AB 396 (Chapter 365, 2025). The ordinance allows accessory dwelling units citywide in zones permitting single-family homes, with permits processed through Development Services under Reno Municipal Code Chapter 18.03.
The Reno City Council adopted the citywide ADU ordinance unanimously on October 8, 2025, codifying the new rules into the Reno Land Development Code at RMC Title 18 (Use Regulations Chapter 18.03). The ordinance implements Nevada AB 396 (2025 session, Chapter 365), which directed qualifying Nevada cities to authorize ADUs by local ordinance. Reno permits one ADU per single-family lot in residential zones, including detached, attached, and interior conversion units. Minimum lot size is approximately 5,000 square feet. The ADU must be smaller and shorter than the primary dwelling and architecturally compatible. Standard setbacks for the underlying zoning district apply. One on-site parking space is required for the ADU. Applications file through the Reno Development Services online permit portal with site plan, floor plans, structural calculations, energy compliance under the adopted IECC, and utility connection plans. Plan review typically takes 15-25 business days.
Building an ADU without permit triggers stop-work orders, double permit fees, and civil penalties under RMC Title 14 (Building Code) and Title 18 (Land Development Code) enforcement. Continued violations face escalating daily fines and potential misdemeanor charges. Liens may be filed on the property.
