The difference between a deck people use twice a month and one they use five nights a week is almost never square footage. It is whether the space works after sunset, in wind, in August heat, and in October cold. Utah's shoulder seasons are long and pleasant, and a few hundred to a few thousand dollars of the right add-ons buys back months of use.
Here is our honest ranking of what is worth it, what to rough in during the build even if you add it later, and what we tell people to skip.
Rough in now, install whenever
Some things are cheap while the framing is open and expensive afterward. Even on a tight budget, we push clients to rough these in:
- Conduit and a junction box at the future fan or heater location, and one at the far corner for lighting. A few hundred dollars now, versus opening a finished ceiling later.
- A dedicated 20-amp circuit to the deck. Heaters, a fridge, and string lights on one household circuit will trip it.
- Blocking in the framing where a privacy wall or screen track will eventually mount.
- A gas stub if a fire feature or grill is ever likely. Trenching after landscaping is finished costs several times more.
Lighting — the highest return of anything on this list
If you do one upgrade, do lighting. It doubles the usable hours of the deck and it is the least expensive item here.
- Riser and stair lights. Safety plus the biggest visual payoff. $60–$110 per fixture installed.
- Post cap lights. Defines the deck edge at night. $70–$140 each.
- Under-rail LED strip. Our favorite — washes the deck surface with no glare. $18–$32 per linear foot.
- Recessed pergola downlights. Turns a pergola into an outdoor room. $120–$200 per light.
Spec warm white at 2700K, not 3000K or higher. Cool light makes composite look grey and washed out. Put everything on a dimmer and one smart switch.
Fans and shade
Utah is dry, so moving air is disproportionately effective — an outdoor-rated fan under a pergola or cover makes a 92-degree afternoon genuinely comfortable in a way it would not in a humid climate.
| Item | Installed cost | Verdict |
|---|---|---|
| Damp/wet-rated ceiling fan under a cover | $650 – $1,400 | Worth it under any roofed structure |
| Retractable shade canopy on a pergola | $1,800 – $4,500 | Worth it on west-facing decks |
| Fixed louvered roof (adjustable) | $95 – $160 / sq ft | Premium, but the most versatile shade there is |
| Shade sail | $400 – $1,200 | Budget option; wind and snow are hard on them |
Shade choice depends heavily on the structure you build. See pergola vs. patio cover vs. pavilion before committing.
Heat — how to stretch the season to nine months
This is where Utah rewards you. Clear, dry October and April evenings are perfectly usable with heat, and heat is where we see the biggest jump in how often a deck gets used.
- Ceiling-mounted electric infrared. Our default. Silent, no fuel, warms objects not air, safe under a cover. $900–$2,200 installed per unit, and needs that dedicated circuit.
- Natural gas overhead heaters. More output for large covered areas, higher install cost due to gas run. $2,000–$4,000.
- Built-in gas fire table. Social rather than practical — it heats the people around it, not the space. $3,500–$9,000 built in.
- Portable propane towers. Cheap, but they tip in canyon wind and everyone stops refilling the tank by year two.
Screens and privacy walls
On the tight lots common in Daybreak, Herriman, Vineyard, and much of Lehi, privacy is the single most requested add-on we get — and it is what turns a deck from a stage into a room.
| Option | Installed cost | Best for |
|---|---|---|
| Slatted privacy wall (composite or cedar) | $110 – $190 / linear ft | Blocking a specific neighbor sightline |
| Louvered privacy screen, adjustable | $180 – $280 / linear ft | Privacy without killing the breeze |
| Motorized retractable screens on a cover | $2,800 – $6,500 per bay | Bugs, wind, and low sun on a covered space |
| Planter wall with built-in seating | $150 – $260 / linear ft | Softening a privacy wall so it doesn't read as a fence |
Motorized screens are the sleeper upgrade on a roofed patio cover. Dropping them converts an open cover into a three-season room in about twenty seconds, and it is the closest thing to adding square footage to the house without a remodel.
What we tell people to skip
- Full outdoor kitchens on decks that get used for dinner twice a month. A gas stub and a good grill covers 90 percent of the use for 10 percent of the cost.
- Outdoor TVs in unroofed locations. Utah sun destroys them and the glare makes them useless at the exact time you would watch.
- Solar post caps. They look great in the catalog and produce almost no usable light by year two.
- Built-in speakers on small decks. A portable speaker sounds better and costs nothing to install.
Everything here can be priced into an initial build. Run your base deck through the cost calculator, then talk through add-ons on the site walk — book one here.
- Rough in conduit, a dedicated 20-amp circuit, blocking, and a gas stub during the build even if you add fixtures later.
- Lighting is the highest-return upgrade: warm 2700K, dimmable, under-rail plus stair risers.
- Ceiling-mounted electric infrared heat is the practical way to stretch a Utah deck to nine months of use.
- Motorized screens on a roofed cover effectively add a three-season room.
- Skip full outdoor kitchens, unroofed TVs, and solar caps — they rarely earn their cost.
Frequently asked questions
+Can add-ons be installed on an existing deck?
Most can. Lighting, privacy walls, and fire features retrofit fine. The expensive retrofits are anything requiring new electrical or gas runs under a finished deck, which is exactly why we push for rough-ins during the original build.
+How much should I budget for add-ons overall?
As a rule of thumb, plan 10 to 20 percent of the deck budget for lighting, power, and one comfort item. A $60,000 deck with $8,000 of lighting, a fan, and heat gets used dramatically more than a $68,000 deck with none of it.
+Do heaters and lighting need a permit?
New electrical circuits and gas lines do require permits in every Wasatch Front city, and they are typically pulled together with the deck permit. Plug-in fixtures on an existing circuit do not.
