Plan smart home infrastructure during design, not after construction. Running low-voltage wiring during framing costs 500 to 2000 dollars. Retrofitting the same system after drywall costs 5000 to 15000 dollars.
Category 6A ethernet to every room (2 drops minimum). Dedicated network closet with rack, switch, and UPS. Wi-Fi 7 access points ceiling-mounted in every major room. This backbone supports everything else. Cost during construction: $3K-$8K. Retrofit: $10K-$25K.
Lutron Caseta, RadioRA, or Homeworks systems. Smart switches (not smart bulbs) for reliability. Scenes: 'Movie mode', 'Dinner party', 'Goodnight'. Motorized shades integrated with lighting. Plan switch locations and circuit groupings during design phase.
Smart thermostat per HVAC zone (Ecobee, Nest). Room-by-room sensors for true zone control. Automated ventilation based on occupancy and air quality. Pool/spa heating schedule integration. All controllable via phone, voice, or automation.
Video doorbell, exterior cameras (4K, PoE), smart locks on all exterior doors, garage door controller. Pre-wire during framing for clean camera placement. Alarm system with professional monitoring. Total: $5K-$15K for a comprehensive system.
Architectural speakers in ceiling/wall for whole-home audio (Sonance, Sonos). Pre-wire speaker locations during framing. Outdoor speakers for pool/patio. Media room: pre-wire for projector, screen, surround sound, acoustic treatment. 4K HDMI and fiber runs to TV locations.

“Smart home technology in LA custom builds has hit a maturity point where the question is no longer whether to include it, but which ecosystem to build around and how much to rough-in during construction for systems the owner may not activate for 2 to 3 years. My standard recommendation is to rough-in conduit and home-run wiring for the top-tier smart home categories — lighting, shades, security, AV — at construction time, then populate the systems selectively at move-in and beyond. Rough-in costs are a fraction of the retrofit cost when walls are closed.”
The single most future-proof smart home infrastructure investment in a new LA build is a fiber optic backbone (not copper ethernet) from the main IT closet to each floor and to the garage and outdoor equipment areas. Fiber is immune to electrical interference, supports any bandwidth standard current or future, and costs only marginally more than copper to install during construction. It will never need upgrading for the life of the building.
1. Selecting a smart home platform based on a single integrator's recommendation without verifying it is compatible with the appliances, HVAC brands, and AV components the homeowner has already chosen
2. Wiring a smart home system without a dedicated IT closet with proper ventilation, UPS power, and structured cabling termination point — then having system failures and heat damage in the first summer
3. Choosing a closed proprietary platform (Crestron, Control4) without a certified local programmer and then finding the system is unusable without expensive service calls when technology changes
Smart home integrators who propose proprietary equipment with no third-party integration capability are creating a locked ecosystem that will cost you dearly when that vendor goes out of business, discontinues support, or raises service fees. Insist on Matter-compatible devices and open standards wherever possible, and ask directly: 'Can I service this system myself or through a different integrator if I choose to?' If the answer is no, look elsewhere.
The must-have integrations in a current LA custom home are: smart lighting with individual dimming and scene control (Lutron Caseta or RadioRA3 for reliability), smart security with cameras and access control, a smart thermostat with multi-zone HVAC control, motorized window shades (particularly valuable in LA's solar exposure), and a whole-home audio system. EV charging management and battery storage monitoring are increasingly standard.
A well-integrated smart home system in a new LA custom build runs $80,000 to $300,000+ depending on scope and brand tier. A more modest but capable system (Lutron lighting, Ring security, Sonos audio, smart HVAC) can be done for $20,000 to $50,000. The cost range is wide because it depends heavily on the number of devices, integration complexity, and whether the owner uses a professional AV integrator vs. a DIY approach.
Yes, for anything beyond basic smart devices. A CEDIA-certified AV integrator in LA programs multi-room audio, motorized shades, lighting scenes, security integration, and HVAC into a coherent system that the homeowner controls from a single app or voice interface. The integrator's programming cost ($10,000 to $40,000) is worth it for complex systems — the same devices without professional programming deliver a fraction of the value.
At a minimum, rough-in: Cat6 or Cat6A ethernet to every room and outdoor living area, conduit from the main electrical panel to a structured wiring enclosure or IT closet, a dedicated circuit for the network equipment, and conduit pathways along all window headers for future motorized shade wiring. These rough-in costs add $5,000 to $15,000 during construction but save $30,000 to $80,000 in retrofit labor if added later.
