Attached & Detached ADUs in NWA

An ADU (Accessory Dwelling Unit) is a self-contained living unit built on the same lot as a single-family home. Under Arkansas law (HB 1503), an ADU is defined as an independently accessed unit with its own cooking, sleeping, and sanitation facilities. ADUs can be attached to your existing home, detached as a standalone structure, or built as an internal conversion. They function as complete, independent homes.

Yes. Arkansas House Bill 1503, effective January 1, 2026, requires all Arkansas municipalities to allow at least one ADU by right on any lot with a single-family home. "By right" means no public hearing, no variance, no conditional use permit, and no special exception is required — just a standard permit application. Cities cannot prohibit ADUs. We handle the full permitting process on your behalf.

Under HB 1503, a detached or attached ADU can be up to 75% of the primary home's gross floor area or 1,000 square feet, whichever is less. For example, if your home is 2,000 sq ft, your ADU can be up to 1,000 sq ft. If your home is 1,200 sq ft, the ADU can be up to 900 sq ft (75% of 1,200). Internal ADUs converted within the existing home do not have separate size restrictions under the law.

No. Arkansas HB 1503 specifically prohibits cities from requiring additional parking spaces for an ADU or charging fees in lieu of parking. The law also prohibits owner-occupancy requirements — meaning neither you nor your tenant is required to live in the primary home or the ADU. There are also no requirements for a familial or employment relationship between occupants of the main home and the ADU.

Most ADUs in Northwest Arkansas fall between $125,000 and $195,000, depending on size, layout, and finishes. Costs vary based on site conditions, foundation requirements, and design choices. We provide transparent, price-locked estimates after a free property analysis — no vague ballparks. Our ADUs are stick-built to custom home standards on permanent foundations, not prefab or manufactured, so you get lasting quality and real property value. The state caps ADU application fees at $250, and cities cannot charge development impact fees above $250.

Yes. ADUs in Arkansas can be used for long-term rentals, housing family members, guest suites, or home offices. Short-term rental rules (like Airbnb stays under 30 days) are regulated separately by each municipality, so check your city's short-term rental ordinance. We can help you understand what is allowed in your area during a free property analysis.

No. Under HB 1503, Arkansas cities cannot require your ADU to match the exterior design, roof pitch, or finishing materials of your primary home. That said, we typically recommend complementary design for curb appeal and resale value — and we custom-design every build to suit your property and preferences.

Most ADU projects are completed in 4 to 6 months from permit approval. The permitting process itself typically takes 4 to 8 weeks depending on the city. We handle all permit applications, drawings, and city coordination on your behalf — you do not have to make a single call to the city.
