💡 What Drives ADU Cost

Foundation: Garage conversions cost less — foundation already exists. Detached casitas need a new slab, electrical sub-feed, plumbing stub-outs.

Permits: Clark County ADU permit fees run $3,000 — $10,000. Included in every quote.

Nevada AB 383: New detached ADUs may require solar installation ($8K — $18K). We factor this in.

HOW IT WORKS

What Order Should ADU Construction Be Done In?

Here is exactly what happens after you call Seven Wells Construction. This is the real sequence we follow on every ADU project in Las Vegas.

Free Site Assessment

We visit your property, walk the lot, measure setbacks, assess your electrical panel, and verify your parcel’s exact jurisdiction. Real assessment, not a phone guess.

Design and Engineering

Architectural drawings and structural engineering documents specific to your jurisdiction — Clark County Title 30, Henderson code, or City of Las Vegas standards.

Permit Application

We submit complete permit packages. Clark County ADU review runs 4 to 8 weeks. Henderson runs 3 to 6 weeks. We track status and respond to plan check comments promptly.

Foundation and Framing

Excavate, set forms, install rebar, and pour the slab for detached ADUs. Las Vegas caliche layers assessed at site visit. Rough plumbing, electrical, and HVAC in sequence.

Finish Work and Inspections

Desert-rated insulation (R-19 walls, R-38 ceiling), drywall, finish work, and all required inspections through your jurisdiction before walls close.

Certificate of Occupancy

Final inspections before the CO is issued. The CO makes your ADU legally rentable and insurable. We resolve all punchlist items before final payment.

LOCAL EXPERTISE MATTERS

Why ADU Construction in Las Vegas Requires a Local Expert

The Caliche Problem

Most Las Vegas Valley lots have caliche hardpan 12 to 36 inches below grade. It behaves like concrete when dry and becomes unstable when saturated. We assess caliche on every site before quoting foundation work.

The Five-Jurisdiction Problem

Las Vegas, Henderson, North Las Vegas, Boulder City, and Clark County each have separate building departments. An ADU permit submitted to the wrong jurisdiction gets rejected and costs weeks.

The HOA Gate

Summerlin, Green Valley Ranch, Anthem, and most master-planned communities require HOA architectural review before any permit application. Building without HOA approval first can result in a stop-work order.

Short-Term Rental Rules

Clark County has an active moratorium on new STR licenses. The City of Las Vegas banned new STRs in most residential zones in 2022. Verify STR status for your specific parcel before designing around Airbnb income.

How long does ADU construction take?+

A garage conversion ADU takes 6 to 10 weeks from permit approval to certificate of occupancy. A detached casita takes 4 to 6 months including permit review (4 to 8 weeks), foundation, framing, rough-in, and finish work.

Do I need a permit to build an ADU?+

Yes. Every ADU type requires permits through the applicable jurisdiction. Unpermitted ADUs cannot be legally rented, cannot be insured as a separate dwelling unit, and create title issues at resale that result in forced removal costs exceeding the original build cost.

Can I rent out my ADU in Las Vegas?+

Long-term rentals of 31+ days are allowed on permitted ADUs across Clark County. Short-term rentals (Airbnb, VRBO) are subject to active moratoriums in parts of Clark County and the City of Las Vegas. Verify your parcel’s STR status before designing around short-term rental income.

How big can an ADU be in Las Vegas?+

Under Clark County Title 30 and Nevada state law, ADUs cannot exceed 50% of the primary dwelling’s floor area, with an absolute maximum of 1,200 sq ft. Setbacks from property lines for detached ADUs are typically 5 feet on side and rear yards.

Do ADUs add value to a Las Vegas home?+

Yes. Permitted ADUs in Henderson and northwest Las Vegas typically add $50K — $120K in appraised value depending on size, finish quality, and location. The value premium is strongest in high-demand rental markets near Desert Foothills, Summerlin Pkwy, and established Henderson neighborhoods.

Can I convert my garage into an ADU?+

Yes — garage conversions are the most cost-effective ADU option in Las Vegas. The foundation and structural walls already exist. Work includes: insulation to Nevada energy code, kitchen with dedicated plumbing, bathroom, upgraded electrical service for a dwelling unit, and a separate entrance with code-compliant egress.
