ADU vs rental property: which has the better ROI in Las Vegas?
The math on traditional rentals isn't working right now. Prices are high, rates are high, and financed investors are lucky to break even. So investors are looking at what they can build on land they already own — and the numbers are a different conversation entirely.
One-bedroom ADU
$95K+
About 400 sq ft, turnkey
Two-bedroom ADU
$125K+
About 576 sq ft, turnkey
Gross yield on cost
~14%
At $1,500/month rent
I went out to Picazzo Homes, a Las Vegas builder that specializes in accessory dwelling units, and asked the questions I had for my own portfolio. What follows is what I learned.
An ADU is a small secondary home on the same lot as the main house — a casita, a pool house, a garage with living space above. Full living space with a kitchen, bathroom and one or two bedrooms.
What you actually get for the price
Picazzo is a division of Western Trades Construction, which has been building for twenty years. Picazzo launched about three years ago as a dedicated ADU team.
| One-bedroom | Two-bedroom | |
|---|---|---|
| Starting price | ~$95,000 | ~$125,000 |
| Size | ~400 sq ft | ~576 sq ft |
| Layout | 1 bed, 1 bath | 2 bed, 1 bath |
| Includes | Site evaluation, plans, permits, full construction — turnkey | |
Those prices are inclusive rather than a starting point that grows. The one-bedroom typically lands around $120,000 once specified.
These are stick-built, not manufactured. They build custom homes, spec homes and commercial — the ADU is built the same way as your front house, which is why they match it.
Warranty is ten years structural and one year mechanical, the same as any new builder. Insurance is straightforward — you add another dwelling to your existing policy.
Same rent, less than half the cost
A two-bedroom ADU at $125,000 rents for somewhere between $1,200 and $1,800 in Las Vegas depending on location. Call it $1,500 — that's $18,000 a year.
To generate that same $1,500 a month by buying a separate condo, townhome or small single-family home, you'd spend $300,000 to $400,000.
The reason is that you already own the expensive part. The land is yours, the utilities are connected, the infrastructure exists. You're paying for the building and nothing else.
Picazzo's own team member built a one-bedroom on his property for $130,000 — slightly upgraded, on an awkward lot — and rents it between $1,650 and $1,725 a month. That's roughly 15 to 16% on cost.
What that 14% figure doesn't include
Worth being straight about, because gross yield on build cost is not the same as return in your pocket.
- Site work and utility connections beyond the base price, plus any unusual permitting
- Utilities — you can't submeter, so you're absorbing them or building them into the rent
- Vacancy, maintenance and turnover, the same as any rental
- Increases to your property tax and insurance once the dwelling is added
- Financing cost, if you're not paying cash
That last one is the big one. Borrow $125,000 on a HELOC at around 8% and you're paying roughly $10,000 a year in interest against $18,000 of rent. Still positive, but a very different number from 14%.
The comparison to a $350,000 rental isn't perfectly like-for-like either, since that purchase would typically be financed too. What's genuinely true is that the ADU requires far less capital to produce the same rent, and that advantage holds however you finance it.
What Las Vegas allows
- One ADU per single-family home — regardless of lot size. A two-acre parcel zoned single-family still gets one house and one ADU
- It can't be larger than the front house — a 3,000 sq ft main house permits up to a 3,000 sq ft casita
- No separate utilities — everything connects to your mains, and submetering isn't permitted unless the property is multi-family
- Everything must be permitted — plumbing, electrical, sewer, gas all run to the existing connections
On utilities, the practical approach is what a landlord does anywhere: work out your cost per square foot from existing bills and build it into the rent.
The real obstacle is HOAs
This is the biggest constraint in Las Vegas. Many master-planned communities don't permit ADUs at all right now. That could change, but as things stand it rules out a large share of the valley.
What works best is a larger lot outside an HOA. Corner lots are particularly worth looking at — you can often position the ADU with its own separate entrance, which makes it feel like a genuinely separate property rather than a shared arrangement.
If you are in an HOA, the builder completes the architectural review forms for you to submit — but approval is still the association's call.
How long it takes
It starts with a feasibility visit. They come to the property and assess plumbing, electrical, soil and lot layout to establish whether a unit will realistically work before anything is committed. An estimate follows within 24 to 48 hours.
| Stage | Timeline |
|---|---|
| Estimate after site evaluation | 24–48 hours |
| Plans and permit pull | 2–3 months |
| Construction | 3–4 months |
| Total commitment | 4–6 months |
They handle permitting themselves — there's a person whose entire job is plans and permits. Timelines shift with the city and inspection scheduling.
How people pay for it
- HELOC against existing equity — the most common route
- Fixed second mortgage — not every lender offers these, but they leave your first mortgage untouched
- Home improvement loans
That second option matters more than it sounds. A lot of Las Vegas homeowners are sitting on 2 to 3% first mortgages and won't refinance for anything. A fixed second lets you access equity without touching that rate.
Ways people are actually using them
House hacking. Live in the main house, rent the ADU.
Reverse house hacking. Live in the ADU and rent out the main house. If you're in a four-bedroom and only need two, this generates considerably more income than the other way around.
Multi-generational living. This is the largest category right now. Aging parents you want nearby, or adult children who've moved back. Senior living communities cost hundreds of thousands — an ADU keeps family close at a fraction of that.
Short and mid-term rental. A casita is a natural fit for furnished rentals without giving up your own home.
Something other than rent entirely. Home office, pool house, guest house, hobby room, golf simulator. Sites like Peerspace let you rent space by the hour as a filming or photography location — around $100 an hour in some markets.
And it adds value to the property
This is real and observable in Las Vegas. Adding a casita or next-gen suite increases resale value significantly, and those properties are in higher demand. You can see it on the resale market and in new-build pricing, where a casita option meaningfully raises the cost to build.
So even if the rental income never materializes the way you planned, you've forced appreciation on an asset you already own.
Location still decides the rent
Picazzo is building across the valley, with a concentration in the Northwest — and a large share of those are for aging parents rather than rentals.
Sun City Anthem has been busier than you'd expect. Those homes are often two bedrooms on small lots, and people love living there but need more space, so front casitas have worked well.
If your goal is rental income, proximity matters. The tenant pool for these is people who need to stay close to work — Strip employees, nurses at UMC and the main hospitals. A well-built casita far from the core is a harder rent.
Most builds are going on lots between 10,000 and 15,000 square feet, though they've fitted units onto 4,000 to 5,000 square foot lots.
ADU FAQ
How much does it cost to build an ADU in Las Vegas?
A one-bedroom of about 400 square feet starts around $95,000 and typically lands near $120,000 once specified. A two-bedroom of about 576 square feet starts around $125,000. Those figures are turnkey, covering site evaluation, plans, permits and full construction, though site work and utility connections on difficult lots can add cost.
Is an ADU a better investment than buying a rental property?
On capital required, generally yes. A $125,000 two-bedroom ADU renting at $1,500 a month produces about 14% gross yield on build cost, while a separate property generating the same rent costs $300,000 to $400,000 for roughly 5%. The advantage is that you already own the land and utilities. That 14% is gross yield rather than net return, so financing costs, utilities, vacancy, maintenance and higher property taxes all come off it.
How much can you rent an ADU for in Las Vegas?
Between $1,200 and $1,800 a month for a two-bedroom, depending heavily on location. Proximity to employment centres matters most, since the tenant pool is largely people who need to be near the Strip or the main hospitals. One owner reports renting a one-bedroom unit between $1,650 and $1,725.
Can I build an ADU if I'm in an HOA?
Often not. Many Las Vegas master-planned communities currently prohibit ADUs, which is the single biggest obstacle in this market. Larger lots outside HOA jurisdiction work best. If you are in an association, the builder can complete the architectural review forms, but approval remains the HOA's decision.
How many ADUs can I build on my property?
One per single-family home, regardless of lot size — a two-acre parcel zoned single-family still permits one house and one accessory dwelling unit. The ADU also cannot exceed the size of the main house, so a 3,000 square foot home permits up to a 3,000 square foot casita.
Can an ADU have its own utilities?
No. Everything connects to your existing mains — water, gas, sewer and electrical — and submetering is not permitted unless the property is zoned multi-family. Landlords typically calculate utility cost per square foot from existing bills and build it into the rent.
How long does it take to build an ADU?
Four to six months from commitment to completion. Plans and permits take two to three months, with construction running another three to four. An estimate follows within 24 to 48 hours of the site evaluation. Timelines vary with city processing and inspection scheduling.
Does your lot work for this?
The first step is understanding your own property — lot size, layout, and whether your HOA permits it. If you're looking to buy with this in mind, large lots outside HOA communities are the ones worth targeting, and corner lots open up separate-entrance layouts.
