Best Casita Builders in Las Vegas 2026
The best casita and ADU builders in Las Vegas for 2026 are Picasa Homes, Jet Development, Vegas Made Construction, and Kingdom & Co. Each firm serves a different segment of the Las Vegas casita market, from dedicated ADU specialists with pre-designed floor plans to full design-build firms handling luxury casitas integrated with a larger home. This guide compares the firms on process, price tier, portfolio, and casita type, so Las Vegas homeowners can identify the right partner for a rental-ready ADU, a multigenerational guest house, or a fully custom luxury casita on their lot.
What is a casita, what is an ADU, and does the difference matter?
In Las Vegas, “casita” and “ADU” (accessory dwelling unit) are used interchangeably. Both refer to a secondary living space on a single-family residential lot, whether attached to the main home or detached in the backyard. Both typically include a private entrance, kitchen or kitchenette, bathroom, and living area, and both can serve as multigenerational housing, a guest suite, a home office, or a rental unit.
The functional difference is scope and finish. A stock ADU floor plan built for rental income is engineered to a different standard than a fully custom luxury casita designed as part of a whole-home estate. The best casita builder for your project depends on where your project falls on that spectrum.
How Nevada AB 396 changed casita construction in Las Vegas
Nevada Assembly Bill 396, signed into law in 2023, requires local jurisdictions to allow accessory dwelling units on single-family residential lots. In Clark County and the City of Las Vegas, this means most homeowners can now legally add a casita to their property, subject to zoning, setback, and HOA requirements.
Key AB 396 provisions relevant to Las Vegas casitas:
- Only one attached or detached ADU is permitted per property.
- ADUs generally cannot exceed 50 percent of the primary dwelling’s floor area or 1,200 square feet, whichever is less.
- ADUs cannot be sold separately from the primary residence.
- Attached ADUs may require a one-hour fire-rated wall between the ADU and main residence.
Confirm your specific parcel’s zoning and HOA rules with your builder before signing a design contract.

1. Picasa Homes
Parent Company: Western Trades Construction Address: 4351 Corporate Center Drive #301, North Las Vegas, NV 89030 Website: picasahomes.com
Picasa Homes is the dedicated casita and ADU builder in Las Vegas, backed by nearly 20 years of Western Trades Construction residential and commercial experience. Picasa operates a full showroom in North Las Vegas where clients can walk through a completed Picasa Home in person before signing a contract. The firm offers two pre-designed and pre-approved floor plans (Picasa 01 and Picasa 02) that shorten the permitting timeline, plus fully custom casita design services for clients who want a bespoke layout. Picasa handles all-inclusive pricing, permitting, and construction end to end with a dedicated Concierge as the single point of contact. Military and first responder discount available.
Best fit for: Rental-ready ADUs, multigenerational guest suites, first-time casita clients who want a fixed floor plan and a showroom walk-through, and clients who value all-inclusive pricing with a shorter permitting path.
Considerations: Picasa’s core product is a casita or ADU as a standalone project. Clients pursuing a luxury casita integrated with a larger custom home or whole-home remodel may prefer a design-build firm handling both.
2. Jet Development
Founded: 1994 Address: 800 N Rainbow Blvd Suite 208, Las Vegas, NV 89107 License: Nevada State Contractors Board #50214 Certification: WBENC-certified woman-owned business Website: jetdevelopmentinc.com
Jet Development has been building custom Las Vegas homes, additions, and remodels for more than 30 years. The firm is one of the few Las Vegas general contractors with WBENC certification, and their casita and ADU work is integrated into a broader portfolio that includes whole-home remodels, home additions, custom homes, and commercial construction. Jet Development operates a Houzz-featured portfolio and serves the greater Las Vegas Valley including Henderson, Summerlin, North Las Vegas, Green Valley, Enterprise, Spring Valley, Paradise, Centennial Hills, and Southern Highlands.
Best fit for: Casitas that are part of a broader construction project (additions, remodels, or custom homes), clients who want a firm with a long Las Vegas track record and general contracting depth, and clients who prefer working with a woman-owned WBENC-certified builder.
Considerations: Jet Development is a full-service general contractor, not a dedicated casita specialist. Clients pursuing exclusively a stock ADU floor plan for the lowest possible price may prefer a specialist.
3. Vegas Made Construction
License: Nevada General Contractor #0090361 Bid Limit: $1 million Certification: Woman-owned, family-owned and operated Website: vegasmadeconstruction.com
Vegas Made Construction is a licensed, bonded, and insured Henderson-and-Las-Vegas general contractor with a documented ADU service line covering both attached and detached units, garage conversions, home additions, new custom homes, and commercial tenant improvements. The firm publishes a transparent ADU timeline guide (6 to 14 months across planning, permitting, and construction) and takes clients from design through final inspection. Business hours are Monday through Friday, 7 a.m. to 5 p.m.
Best fit for: Henderson and Las Vegas homeowners pursuing a detached or attached ADU, clients who want a woman-owned family-operated firm, and clients whose project falls comfortably within a $1 million total scope.
Considerations: Vegas Made’s bid limit is $1 million. Luxury custom casitas exceeding that threshold, or casitas integrated with a larger luxury custom home, may fit better with a firm scoped for higher-tier work.
4. Kingdom & Co.
Founders: Brian Horner, Lincoln Rogers, and John McDonough Signature style: Luxury custom casitas designed for the client, not the catalog Neighborhoods: Summerlin, The Lakes, MacDonald Highlands, Ascaya, Southern Highlands, Centennial Hills, Henderson, Anthem Country Club, Lake Las Vegas, valley-wide
Kingdom & Co. is the Las Vegas luxury design-build firm handling casitas across every scope: standalone luxury casitas designed as detached backyard estates, casitas integrated into whole-home remodels, and casitas included in new custom home construction. Every casita is designed specifically for the client rather than fit to a stock plan, with the same integrated architecture, interior design, and construction team from the first meeting to move-in.
Kingdom & Co. casitas have included multigenerational suites for aging parents, dedicated home-office casitas for remote-working clients, and luxury guest houses paired with resort-scale primary residences. The firm handles the design, the permitting, and the construction under one contract, and the same finish level applied to the main home is applied to the casita.
Kingdom & Co. has been recognized with NARI Contractor of the Year, listing in the Architectural Digest AD Pro Directory for 2024, 2025, and 2026, Best of Las Vegas Gold Winner for Custom Home Builder 2025, features across eight episodes of HGTV Property Brothers, editorial coverage by Martha Stewart’s team, and a Better Business Bureau A+ rating held since 2018. The firm carries a 4.8-star Google Business Profile rating across 40 reviews.
Best fit for: Luxury custom casitas at any scope tier, casitas integrated with a whole-home remodel or new custom home, aging-parent multigenerational suites where finish quality and privacy design matter as much as function, and clients relocating from out of state who need remote project management.
Considerations: Kingdom & Co. is design-build first. Clients pursuing a pre-approved stock ADU floor plan for the lowest possible price should look at Picasa Homes first.

Frequently asked questions about Las Vegas casita builders
Casita and ADU costs in Las Vegas vary widely by size, finish tier, and whether the unit is attached or detached. Stock ADU floor plans start in the $150,000 to $250,000 range for a fully built detached unit under 800 square feet. Fully custom luxury casitas designed by a design-build firm typically start at $350,000 and range up to $750,000 or more depending on square footage, finish level, and site conditions. Detached ADUs cost more than attached due to new foundation, utilities, and standalone framing.
An ADU in Las Vegas is functionally the same as a casita and follows the same pricing structure. A garage conversion ADU is typically the least expensive option at $80,000 to $150,000 because it reuses the existing structure. An attached ADU addition to the main home is next at $150,000 to $300,000. A detached ADU with new foundation, standalone utilities, and full framing starts around $200,000 for a stock plan and $350,000 or more for a fully custom design.
Yes. Under Nevada Assembly Bill 396, signed into law in 2023, local jurisdictions in Nevada are required to allow accessory dwelling units on single-family residential lots. In Clark County and the City of Las Vegas, most homeowners can add one attached or detached ADU to their property, subject to setback rules, size limits (generally not exceeding 50 percent of the primary dwelling or 1,200 square feet), and HOA guidelines.
Casita and ADU construction in Las Vegas typically takes 6 to 14 months from initial consultation to keys, broken into three phases: planning and design (1 to 3 months), permitting and approvals (2 to 6 months), and construction (4 to 9 months). Garage conversion ADUs can be completed faster because they reuse existing structure. Detached custom casitas take the longest due to foundation work and standalone utility connections.
It depends on your local zoning, HOA rules, and short-term rental regulations. Long-term rentals (30+ days) are generally permitted in most Clark County residential zones. Short-term rentals (under 30 days) are subject to Clark County’s short-term rental ordinance and municipal-specific rules that vary between the City of Las Vegas, Henderson, North Las Vegas, and unincorporated Clark County. Always confirm with your builder and HOA before finalizing your casita design.
No. Under Nevada AB 396 and Clark County zoning, an ADU or casita cannot be sold separately from the primary residence. It remains part of the same parcel and title.
Generally, an ADU in Clark County and the City of Las Vegas cannot exceed 50 percent of the primary dwelling’s floor area, and cannot exceed 1,200 square feet regardless of the main home’s size. Some jurisdictions have additional height and setback restrictions.
