Quick Answer
What smart home systems does an ADU need?
Every ADU needs four systems as infrastructure, not add-ons: networking (a rental ADU gets its own VLAN-isolated network; a family ADU shares infrastructure with separate SSIDs), security (an independent Ajax system for tenants, or a partition on the main hub for family), Control4 automation (a CORE controller giving the ADU full smart home function — lighting, thermostat, locks, AV — independent or integrated), and AV (in-ceiling speakers, clean TV mounting, streaming). Rivas Technology Group specifies all four as one coordinated system and roughs them in during construction — when it’s clean, concealed, and 40–60% cheaper than retrofitting.

HB 1337 Is Live. The ADU Boom Is Here.

Washington’s House Bill 1337, fully effective July 1, 2025, allows up to two ADUs per residential lot across King and Pierce Counties — attached, detached, or one of each. No owner-occupancy requirement, streamlined permitting, impact fees capped at 50%. The barriers are gone. The question now is what goes inside.

Rental-Ready Infrastructure

A rental ADU is a business — it needs tenant-grade separation and owner-grade oversight.

  • VLAN-isolated network — completely separate from your home
  • Independent Ajax security the tenant controls
  • Smart locks and access you manage remotely
  • No monthly fees unless you choose monitoring

Multigenerational Done Right

A family ADU shares infrastructure without sacrificing independence.

  • Shared network with separate SSIDs and access controls
  • Ajax partition on the main hub — one system, private zones
  • Control4 CORE — its own app, keypad, or remote
  • Aging-in-place friendly: lighting, locks, and climate simplified

Wire It During Construction

Rough-in while the walls are open costs a fraction of retrofit — and looks like it was always meant to be there.

  • Cat6A, speaker runs, and conduit at framing
  • Clean concealed AV — no visible cable, ever
  • 40–60% less than post-construction retrofit
  • Coordinated with your ADU builder’s schedule

Four Systems. One Coordinated Design.

An ADU is a complete dwelling — it needs all four, specified together, not four separate contractor relationships.

📡 Networking

Separate & Secure WiFi

Rental: VLAN-isolated, completely separate from the main home. Family: shared infrastructure, separate SSIDs. Alta Labs or Island hardware for rock-solid coverage across both structures.

🔒 Security

Independent or Integrated Ajax

Rental: the tenant’s own panel, no access to the main system. Family: a partition on the main hub. Door/window sensors, motion, cameras, and the Ajax app standard.

🎛️ Automation + AV

Control4 CORE & Complete AV

A Control4 CORE controller gives the ADU full smart home function — lighting, thermostat, locks, and AV from one interface. In-ceiling speakers, clean TV mounting, streaming integrated.

ADU Smart Home Automation FAQs

What did HB 1337 change for ADUs?

Fully effective July 1, 2025: up to two ADUs per residential lot across King and Pierce Counties — attached, detached, or one of each — up to 1,000 sq ft per unit. No owner-occupancy requirement, streamlined permitting, impact fees capped at 50% of the primary residence rate, and HOAs cannot impose new ADU restrictions. It's the most significant change to ADU law in Washington State history.

Does a rental ADU really need its own network?

Yes — a rental ADU needs VLAN-level isolation from your home network. Your tenant's devices should never share a network with your cameras, computers, and smart home controllers. We design the architecture based on your use case and build it with Alta Labs or Island hardware.

How does security work with a tenant?

The tenant gets their own Ajax system — their own panel, their own app, no access to your main home system. You retain what an owner needs: smart lock control and property oversight. For family ADUs, we run a partition on your main Ajax hub instead — one system, private zones.

When should I involve you in my ADU build?

At the planning stage, before framing. Rough-in during construction — Cat6A, speaker runs, conduit — costs 40–60% less than retrofitting and results in fully concealed infrastructure. We coordinate with your ADU builder's schedule.

How much does ADU smart home infrastructure cost?

Rough-in packages during construction are the affordable entry point; complete ADU systems with networking, Ajax security, Control4 CORE, and AV typically land well below whole-home pricing because the footprint is under 1,000 sq ft. Free consultation, fixed proposal, tax included.

Can the ADU integrate with my main home's smart home system?

Either way — fully independent (its own Control4 CORE, its own app) or tightly integrated with the main house. Rental units get independence; family suites usually get integration. We design for your use case.
