Key Takeaways

  • The single best smart-home decision is structured Cat6 + smurf-tube to every TV, office, and control location — done during construction or remodel, before drywall.
  • Smart electrical panels (Span, Schneider Energy Center) make sense for all-electric homes with multiple EVs, solar+battery — not typical single-family homes.
  • WiFi-only devices don't age well. The wired backbone is the durable layer; radios change every 3-5 years.
  • Lutron Caseta is the workhorse smart-control system for Marin homes — local control, no cloud dependency, 12+ year track record.
  • Smart-home wiring should be designed before any device is purchased. Devices follow the network.
Towery Electric — Smart-Home Electrical.

01 — OverviewWhat Smart-Home Electrical actually covers in Marin.

Smart-home electrical work has two distinct layers. First is the structured low-voltage backbone — Cat6 cabling, sometimes fiber, conduit runs. This is the durable infrastructure that supports every device generation for 20-30 years. Second is the smart electrical platforms — Lutron lighting control, Span smart panels, automated shading. These depend on the backbone underneath.

The most common bad outcome is buying smart devices before wiring the home. Homeowners end up with WiFi-dependent stacks that work for two years and become unsupported. The right sequence is wire first (during access), then choose devices that ride on the wired backbone.

Definition

Smart-home electrical infrastructure is the combination of structured low-voltage cabling (Cat6, fiber, smurf-tube) and smart power-management platforms (Lutron, Span, Schneider) enabling home automation, energy management, and integrated control.

Structured wiring — the durable layer

Cat6 to every TV, office, and feature location, plus smurf-tube conduit for future cable replacement, creates 30-year infrastructure that outlasts every device. Cost during construction is modest ($1,800-$4,500); retrofit cost is dramatically higher.

Smart panels — when they make sense

Span Panel and Schneider Energy Center add per-circuit monitoring and app control. Make sense for all-electric estates with multiple EVs, solar+battery, active load management. For typical homes, conventional panels with discrete smart breakers deliver 80% of value at 30% of cost.

For the broader context this guide supports, see our Residential Electrical Services overview.

02Structured wiring cost (Marin, 2026).

Cost depends on home size and whether wiring goes in during open-wall work or retrofit.

New-build / open-wall ($1,800-$4,500)

Cat6 to every room, smurf-tube to feature locations, central rack closet.

Retrofit through finished walls ($4,500-$11,000)

Fishing Cat6 through occupied-home walls. Cost scales with complexity and access points.

Smart panel install ($6,500-$11,500)

Span Panel or Schneider Energy Center during a panel upgrade. App setup and circuit naming included.

03Why WiFi-only smart homes age poorly.

The pattern repeats every 3-5 years. A homeowner buys 30 WiFi devices, the cloud service is deprecated, half the devices stop working, the cycle restarts.

Local control over cloud control

Lutron Caseta, HomeWorks, and most professional platforms control locally — the network keeps working even if the cloud goes down. WiFi-only devices typically don't.

The 10-year horizon

Choose platforms with 10+ year manufacturer support and parts availability. Lutron, Crestron, Control4, Savant clear this bar. Most consumer smart-home brands don't.

04Smart-home installation timeline.

Typical smart-home electrical scope runs 2-6 weeks.

Days 1–30

Design and infrastructure

Walk-through, structured-wiring plan, control-platform selection, rough-in scheduling.

Days 31–60

Rough-in and termination

Cat6 pulled, conduit installed, jacks terminated, smart-panel mounted, breakers installed.

Days 61–90

Platform commissioning

Lutron scenes programmed, smart-panel circuits named, app setup, homeowner walkthrough.

05Choosing a smart-home electrician.

Smart-home work crosses electrical, low-voltage, and integration scopes. The C-10 holding it together has to know all three.

Multi-platform certification

Lutron certified for Caseta and HomeWorks, plus structured-wiring experience. Bonus: integration with Sonos, Crestron, Savant.

Design-first conversation

The first conversation should be about how you'll use the home — not which devices you've already bought.

Frequently Asked Questions

What's the difference between structured wiring and WiFi?
Structured wiring is permanent Cat6 cabling through walls to every room and key location, terminating at a central rack. WiFi is wireless — radios talk through the air. Structured wiring is faster, more reliable, doesn't suffer neighbor interference, and supports every wired device. WiFi is convenient but performance-limited. Most professional smart-home installs use both: structured wiring for infrastructure, WiFi for mobile devices.
Are smart electrical panels worth the cost?
For most Marin single-family homes, no — they're a premium product for a use case most homes don't have. Smart panels (Span, Schneider) cost $4,000-$7,000 more than conventional and add per-circuit monitoring and app control. Strong case for all-electric homes with multiple EVs, solar+battery, active load management. For typical homes, conventional panel + smart breakers delivers most value at 30% of cost.
How much does smart-home electrical infrastructure cost?
Structured wiring during new construction or major remodel: $1,800-$4,500. Retrofit through finished walls: $4,500-$11,000. Smart electrical panel during upgrade: adds $4,500-$7,000 over conventional. Lutron Caseta whole-home: $2,400-$4,800 retrofit; HomeWorks: $14,000-$38,000. We quote each scope based on home and goals.
Will my smart-home devices still work in 10 years?
Depends entirely on platform. Professional platforms (Lutron, Crestron, Control4, Savant) have 10+ year manufacturer support, controllers that update, and replacement parts. Consumer WiFi platforms have 3-5 year life — cloud service deprecated or app stops being updated. Structured wiring layer (Cat6, conduit) lasts 30+ years regardless of devices.
Can I retrofit a smart-home system into an existing home?
Yes, different scope depending on what you want. Lutron Caseta retrofits without opening walls — wireless smart switches replace conventional one-for-one. Structured wiring retrofits require fishing Cat6 through finished walls; costs more but feasible. Smart panels are part of a panel-upgrade project. We walk every retrofit in person to identify scope.
Do smart-home upgrades require permits?
Depends on what you're doing. Low-voltage cabling (Cat6, speaker wire) generally doesn't require a permit. Smart electrical panels do — they're a panel-upgrade scope. Lutron smart switches replacing existing switches generally don't (like-for-like). New circuits for new outlets, hardwired controllers, or panels require permits. We pull when needed.
