ADU in Las Vegas/Henderson Area

[Rico Nasol]

I am investing in the Las Vegas and Henderson area of Nevada. Some of the older but still safe areas have older homes with HUGE lots. I have been trying to do more research on ADUs. It's become a solid strategy in CA where I'm from for adding additional rental units onto a SFR parcel. Has anyone had success doing this or understand what some of the zoning laws allow? I read the Clark County zoning guide and from what I can gather, anything zoned RS-1, 2, 4 or 6 can have an ADU but they have to follow the same setback requirements and can't exceed 25% of the main dwelling. Does anyone have any other info they can share?
