Reno Just Updated Its ADU Rules: What Homeowners & Investors Need to Know

Reno just unlocked a major opportunity for homeowners and investors: the city’s updated ADU ordinance makes it easier than ever to build income-generating units in Northern Nevada’s fastest-growing neighborhoods.

Introduction

The City of Reno has officially adopted new Accessory Dwelling Unit (ADU) regulations, effective October 2025; a major win for homeowners and out-of-state investors seeking new income opportunities in Northern Nevada’s growing housing market.

ADUs, often called granny flats, casitas, or guest houses, provide flexible housing solutions that can increase property value, create passive rental income, and help address housing demand.

This guide breaks down everything you need to know about Reno’s new ADU ordinance,  from lot size and design rules to rental allowances and estimated fees.

What Is an Accessory Dwelling Unit (ADU)?

An ADU is a secondary home on the same lot as a single-family residence.
It can be:

• Attached ADU – integrated with the primary home (e.g., over-garage or basement unit)

• Detached ADU – a separate backyard structure, cottage, or guest house

ADUs are becoming a powerful tool for housing affordability, multi-generational living, and investment diversification.
