Henderson permits ADUs under its own development code, not the City of Las Vegas or Clark County code. According to June 2026 reporting, the city made sweeping ADU changes in 2022 based on American Planning Association recommendations and passed minor changes in fall 2025 to fully comply with AB 396.
What does AB 396 require of Henderson?
As a city of more than 60,000 people, Henderson must allow ADUs on single-family zoned property. As of October 2026, its ordinance cannot ban a separate kitchen, require stricter side or rear setbacks than the house, or bar long-term rental of the unit, though it may bar transient lodging use.
What usually matters on a Henderson lot?
- The HOA. Large master-planned communities often have their own architectural guidelines. Review usually comes before the city permit. See the HOA guide.
- Hillside and view lots. Slopes and view corridors can limit height and placement.
- Pool and patio layout. Many yards are already full; an attached ADU or garage conversion can fit where a casita cannot.
What do Henderson rentals bring?
Apartment List's late-October 2026 report listed Henderson as the most expensive city in its Las Vegas metro list, with a $1,624 median. See casita rents.
