Johnston County has quietly become one of the most active new construction markets in the greater Triangle. Wayne Lanier has been coordinating low-voltage pre-wire with builders working in Clayton, Smithfield, Four Oaks, and the surrounding area for years. Here is what local contractors should know.

If you are building or renovating homes in Johnston County right now, you are working in one of the fastest-changing markets in the region. Clayton alone has seen its population more than double over the past 15 years, driven largely by its proximity to the Research Triangle job corridor and significantly lower land costs compared to Wake County. Smithfield and Four Oaks are seeing similar, if more gradual, growth as buyers continue moving outward in search of larger lots and new construction at a more accessible price point.

This growth brings a wave of buyers who expect the same connected, modern home experience they would get in a new Wake County subdivision, but who are sometimes building on larger acreage lots, in more rural settings, or working with a different mix of regional builders than what dominates the Wake County market.

Wayne Lanier has been the low-voltage pre-wire contractor for builders throughout Johnston County for years, working alongside his core Wake County client base. Here is what he wants Johnston County contractors to understand about getting AV and smart home pre-wire right.

1. Why Johnston County Is the Triangle's Next Growth Frontier

As Wake County land prices have climbed, Johnston County has absorbed a meaningful share of the Triangle's growth. Clayton's population has grown dramatically since the early 2010s, and the town's proximity to both Raleigh and the I-40 corridor makes it an increasingly attractive option for buyers who are priced out of inner Wake County but still want a reasonable commute.

This shift means more new construction activity, more renovation work on existing rural and small-town housing stock, and a buyer pool that increasingly resembles the tech-forward, connectivity-expecting demographic that has defined Wake County's growth for the past decade. The expectations have shifted even where the land use patterns have not caught up yet.

2. What Is Different About Building in Johnston County Versus Wake County

A few practical differences matter for low-voltage planning specifically.

Larger Lot Sizes and Acreage Builds

Johnston County zoning and land availability support larger lots than much of Wake County, including significant acreage properties. This changes the calculus for outdoor speaker runs, exterior camera coverage, and Wi-Fi access point placement, since covering a larger property requires different infrastructure planning than a standard quarter-acre suburban lot.

More Septic and Well Systems

Many Johnston County properties, particularly outside the core municipal areas of Clayton and Smithfield, rely on septic systems and private wells rather than municipal utilities. This affects the physical layout of underground utility runs and requires more careful coordination to avoid conflicts between low-voltage conduit runs and septic field locations.

A Different Builder Mix

While DR Horton, Lennar, and other national production builders are active in Johnston County, the market also includes a higher proportion of smaller regional and custom builders compared to the dominant national-builder presence in much of Wake County's newest subdivisions. This often means more flexibility in pre-wire specifications but also less standardized structured wiring packages, which makes a knowledgeable low-voltage partner more important, not less.

Wayne's experience: "Johnston County builds give me more room to recommend the right approach because I am often dealing directly with the builder or the homeowner rather than working within a rigid production builder template. That flexibility is valuable, but it also means nothing happens unless someone proactively plans for it. There is no default smart home package to fall back on."

3. The Pre-Wire Specification Johnston County Builders Should Be Using

The core specification mirrors what Wayne recommends for any Triangle-area new construction project, with a few Johnston County-specific additions.

Standard Pre-Wire Scope

Cat6 home runs from every room to a centralized network closet or structured wiring panel
Speaker wire rough-in for living room surround sound, minimum 5.1 configuration
HDMI conduit from TV wall locations to equipment closet or media console
Low-voltage conduit for exterior security camera locations at all entry points
Pre-wire for a video doorbell at the front entry

Johnston County and Acreage-Specific Additions

Extended Wi-Fi access point planning for larger homes or properties with detached structures like workshops, barns, or guest houses
Direct-burial rated conduit runs for any outdoor camera or speaker wiring that crosses open yard areas, which are more common on larger Johnston County lots
Coordination with the septic and well contractor to confirm utility easements before planning underground low-voltage runs
Consideration of point-to-point wireless network bridges for detached structures where running wire is impractical due to distance

4. Coordinating With Rural and Acreage Lot Builds

Acreage and rural builds in Johnston County require a different planning conversation than a standard suburban subdivision lot. Wayne typically recommends addressing a few specific questions early in the design phase.

How far is the network closet or structured wiring panel from the furthest point that needs connectivity, including any detached structures? This determines whether wired Cat6 runs are practical or whether a wireless bridge solution makes more sense.
Are there plans for outdoor entertainment areas, including a pool, detached patio, or outbuilding, that will need speaker wire or camera coverage run across open yard space? Planning this during the rough-in phase, even if installation happens later, avoids a costly retrofit.
What is the property's topography and where do existing or planned utility easements fall? This affects where underground conduit runs can be placed without conflicting with septic fields, well locations, or utility company easements.

Addressing these questions during the design and pre-construction phase, rather than during the rough-in phase itself, gives Wayne the information needed to plan an efficient, conflict-free low-voltage layout.

5. What Johnston County Homebuyers Are Actually Asking For

Wayne's conversations with Johnston County homebuyers, both through builder referrals and direct homeowner consultations, reveal consistent priorities. Whole-home Wi-Fi coverage is a top concern, particularly for larger homes and properties with detached structures where a single router cannot provide adequate coverage. Outdoor entertainment, including speakers and TVs for patios, pool areas, and outbuildings, ranks highly given the larger outdoor living spaces common in the area. And smart security, including exterior cameras covering larger properties with more entry points and approach paths, is a frequent request.

Builders who can speak knowledgeably about these priorities during the sales process, even if the actual installation happens through a referral to a contractor like Wayne, differentiate themselves in a competitive new construction market.

Frequently Asked Questions for Johnston County Builders

Do you serve builders outside of Clayton, in Smithfield, Four Oaks, or Selma?

Yes. Wayne serves builders and homeowners throughout Johnston County, including Clayton, Smithfield, Four Oaks, Selma, and the surrounding unincorporated areas. He has experience with both municipal lot builds and larger acreage properties throughout the county.

How does pricing differ for acreage builds compared to standard suburban lots?

Acreage builds typically involve more wire and conduit due to longer distances between the structured wiring panel and outdoor or detached locations. Wayne provides itemized quotes based on the specific scope of each project, taking lot size and structure layout into account during the initial assessment.

Can you handle pre-wire for a detached garage, workshop, or guest house?

Yes. Detached structures require either a wired connection back to the main network closet or, in some cases, a wireless point-to-point bridge if the distance or terrain makes wiring impractical. Wayne assesses each property to determine the most reliable and cost-effective approach.

What if our development does not have a standard low-voltage package built into the build process?

This is common in Johnston County's mix of custom and regional builder projects. Wayne can work directly with the builder to develop a standard pre-wire package that can be offered to homebuyers as a selection center option, similar to what he has helped establish for builders in the Wake County market.

How far in advance should we contact you for a Johnston County project?

Two to four weeks of lead time before the rough-in phase is ideal, similar to Wake County projects. For acreage builds with more complex utility coordination, earlier engagement during the design phase helps avoid conflicts with septic, well, and utility easement planning.
