Deck Layouts for Commencement Bay and Mount Rainier Views: Height, Orientation, and Sightlines

By Daniel Rotaru, Owner and CEO at Decks Restore. WA Contractor License # CC DECKSRL797P2. Tacoma, WA. Updated October 2026.

If your house looks out over Commencement Bay or toward Mount Rainier, the deck has to be designed around the view. A view deck gets judged from a chair, and the usual mistakes come from decisions made standing up: a top rail that sits right at seated eye level, a cover post planted in the middle of the mountain, or a deck aimed at the water that gets so much glare by 5 p.m. that nobody uses it.

Below is how we work through those decisions on Tacoma lots, plus the city rules that limit how high and how far out a deck can go.

The short answer

Start with where people will sit and what they’ll look at, then set the deck height and railing so the top rail stays below seated eye level and nothing solid lands in the line of the view. In Tacoma, any part of a deck more than 30 inches above grade needs a guard at least 36 inches high, with openings small enough that a 4-inch sphere can’t pass through. Homes in a View-Sensitive Overlay District have a 20 or 25 foot height limit that the whole structure has to fit under, and zoning setbacks cap how far an elevated deck can push toward the property line. Rainier sits southeast of the city, so a deck aimed at the mountain gets morning sun and shade from the house by late afternoon. A deck in Northeast Tacoma looking southwest across the bay gets the opposite: hot afternoons and glare off the water.

Find the sightline before you pick a height

Tacoma’s view lots point in different directions depending on the neighborhood. From the bluff above Ruston Way and parts of Old Town and the North End, the bay is to the north and east and Rainier is off to the southeast. Northeast Tacoma looks back across the bay toward downtown and the Port, with the mountain to the south and southeast. From Hilltop and the Stadium District, Rainier and the Tideflats are to the east and southeast. Rainier is a little over 40 miles from downtown, and at 14,410 feet it sits only a few degrees above the horizon, so anything tall in the foreground can cover it.

Before anyone draws a plan, get your eyes to the height they’ll be at once the deck is built. Set up a stepladder at the spot where the deck would be and stand on the step that puts your feet at the planned deck height. Then take photos at two heights: standing, and crouched to where your eyes would be in a chair. A seated adult’s eyes are usually around 4 feet above the floor in a dining chair, lower in an Adirondack or lounge chair, and a standing adult’s are somewhere around 5 feet. Use your phone’s compass to note the direction of the view and mark what’s in the way, whether that’s the neighbor’s roofline, a fence, a street tree, or the power lines in the alley.

Those photos settle most height arguments. Sometimes the extra two feet you were planning buys nothing, because the obstruction is a roof you clear easily either way. Sometimes it’s the difference between seeing the water and seeing a gutter.

Height: what each foot gets you

Under 30 inches, nothing has to stand between you and the view

A guard is required where the walking surface is more than 30 inches above the floor or grade below at any point within 36 inches of the edge. Stay under that and the view side can stay open. On a lot that drops away toward the water, that usually only works close to the house. One way around it is to split a view deck into two levels: a lower lounge area kept under the guard threshold on the view side, and a higher dining level near the door. The step between them doubles as a long, low bench.

One step down from the door keeps the rail out of the indoor view

The residential code allows the deck surface to sit up to 7¾ inches below the top of the door threshold, as long as the door doesn’t swing out over the deck. Sliders and inswing doors both qualify. Dropping the deck that much moves the top rail down by the same amount relative to everyone sitting inside, and in Tacoma you’ll look at this view through the window more days than you’ll sit outside in it. Take someone in a dining chair inside, with their eyes about 4 feet above the interior floor. With a flush deck, a 36-inch rail sits 12 inches below their eye line. Drop the deck 7 inches and the rail sits 19 inches below it. A step down also keeps rain from driving under the door, which we’d want anyway.

Tall decks cost more and change what the neighbors see

Every foot of height means longer posts, more bracing, and on the tallest decks, engineering for lateral loads from wind and earthquakes. The city’s deck tip sheet calls for tension ties at the house connection when the deck relies on a lateral load connection, and steep lots bring their own soil and footing questions. If your lot falls off sharply, our post on building on a steep North End lot goes through footings, setbacks, and critical area review.

A tall deck is also visible from below. Neighbors downhill see posts and the underside, and you see more of their yard. We plan the beam and post layout so the underside looks finished from the street and from the yard below, and we put privacy screens on the side lot lines, where they block the neighbors without touching the view.

View-Sensitive Districts cap the height

Parts of Tacoma sit in a View-Sensitive Overlay District, an overlay the city created for neighborhoods with long-established homes that look out at Puget Sound or the Narrows Bridge. Since 2021 there are two versions: VS-20, with a 20-foot height limit, and VS-25, with a 25-foot limit. The limit applies to all buildings and structures, and height is measured as a plane drawn above four base elevation points at the corners of the foundation. The city’s tip sheet on these districts notes that decks and porches beyond the foundation aren’t counted when the city calculates the extra height allowed on a sloped lot, and that no part of the structure can extend above the height plane.

For an ordinary deck off the main floor, that limit rarely comes into play. It matters for rooftop decks, upper-level decks with a cover over them, and guardrails on a roof, all of which can push part of the house above the plane. The city may require a height survey from a licensed surveyor, so if you’re in one of these districts, plan for that cost and time. The same limits apply to your neighbors, which is part of what keeps views open in those areas. Some larger subdivisions also have their own recorded view covenants and an architectural committee that has to approve plans before they go to the city.

Setbacks limit how far the deck can reach toward the view

View lots tempt people to push the deck as far toward the edge as it’ll go. Tacoma’s zoning code lets uncovered decks project into required setbacks by different amounts depending on height. A deck no more than 30 inches above grade can cover up to half of a required setback area and come within 3 feet of a side property line. A deck between 30 inches and 8 feet up can extend up to 8 feet into a front or rear setback. Above 8 feet, the allowance drops to 4 feet into a front or rear setback and 2 feet into other required yards. These allowances are written for uncovered decks. If you plan a roof over the deck, ask the city how the setback applies before you design it.

Orientation: where the sun and the view line up

Tacoma is far enough north that the sun moves a long way across the sky between June and December. In late June it rises in the northeast and sets in the northwest, and at noon it’s high in the sky. Around the winter solstice it rises in the southeast, close to the direction of Rainier from most of the city, and never gets more than about 20 degrees above the horizon.

That has a few practical consequences:

• A deck aimed at Rainier gets morning sun and falls into the shade of the house by late afternoon. On clear summer evenings that works in your favor, because the setting sun lights up the west face of the mountain while you sit in the shade. On winter mornings you’ll be looking at the mountain with a low sun right behind it.
• A North End deck facing northeast over the bay is the coolest of the common layouts. It’s bright in the morning and shaded from midday on, which suits people who want to eat outside in August without a cover.
• A Northeast Tacoma deck facing southwest across the bay gets the full afternoon sun plus glare off the water. These are the decks where shade decides whether anyone sits outside after 3 p.m. in summer.
• Exposed bluff decks catch wind off the water. Glass panels on the windward side take the edge off it, and so does a wall of the house if the layout can wrap around a corner.

If you want shade on a view deck, the cover can’t be an afterthought. Posts belong at the ends of the view, never in the middle, and the beam needs to sit high enough that a seated person looking out sees sky under it. On west and southwest exposures we often recommend a louvered roof that opens on clear days, or a clear acrylic cover where the goal is keeping rain off without darkening the room behind the deck. If the deck is on the second floor, read up on the guardrail conflicts that come with covering a second-story deck before you choose one.

Sightlines from the seats

Railings

The city’s residential porches and decks tip sheet sets out the guard rules: required on open sides more than 30 inches above the floor or grade below, at least 36 inches high, and built so a 4-inch sphere can’t pass through. A 36-inch rail is about a foot below the eyes of someone in a dining chair. In a low Adirondack chair, it can sit right in the line of sight.

On the view side, we keep the guard at the 36-inch minimum unless there’s a reason to go higher, use cable or glass infill, and choose the thinnest top rail the system allows. Wide drink rails are great for leaning on, but from a chair a 5 or 6 inch flat top hides more of the yard and shoreline just past the deck, so we put them on the side runs instead. Each infill type has tradeoffs in a wet climate, and I went through what each railing type costs you in upkeep over ten years in a separate post.

Posts, stairs, and everything else on the deck

• Line up railing posts with the window frames and mullions inside the house, so from the living room the posts hide behind framing you already look past.
• Run stairs off the side of the deck. Stairs on the view side bring a second set of posts and a gap in the railing line, right in front of the best seat.
• Keep tall items to the sides or against the house: hot tubs, grills, planters, heaters, and umbrella stands. Sketch the view from your main seat as a wedge on the plan and keep anything over rail height out of it.
• Look at the deck from inside, too. Stand at the kitchen sink and sit on the couch before you approve the layout, because those are the spots you’ll see it from all winter.

Trees in the way

You can prune a tree on your own property without a city permit. A tree in the planting strip needs a permit before it’s pruned, and topping it is not allowed. You can’t prune or remove a tree on a neighbor’s property, and the city doesn’t prune or remove trees to preserve anyone’s view. There’s a narrow exception for trees on city-owned land, where the code allows pruning for scenic view enhancement by permit, at the applicant’s expense. There’s more on Tacoma’s rules for pruning and removing trees in our post on building a deck around a mature tree.

Keeping the night view

After dark, a lot of Tacoma view decks look out at the lights of downtown and the Port. Bright deck lights turn glass panels into mirrors and wash out everything past the rail. We keep lighting low and shielded: stair lights, post cap lights pointed down, and strip lights under the top rail. Hardwired lighting and outlets can mean an extra permit, and I wrote up when deck lighting needs its own electrical permit.

Materials close to the water

Decks on the Ruston Way bluff and the Northeast Tacoma shoreline get salt in the air, and it shows up first on fasteners and cable fittings. Glass also needs more cleaning near the water to stay clear. We specify hardware that survives salt air off the bay on these jobs, since a rusty cable fitting is right in the view.

Common questions

How high should a deck be to see over my neighbor’s roof or fence?

High enough that your eyes clear the obstruction from where you’ll sit, which is usually around 4 feet above the deck surface in a dining chair. The quickest way to find out is to stand on a stepladder at the planned deck height and photograph the view at seated and standing eye level.

What railing is best for a view deck in Tacoma?

Glass or cable infill with a slim top rail at the 36-inch minimum height keeps the most view. Glass blocks wind better and needs more cleaning in our weather. Cable is less visible from a distance and needs periodic tensioning.

Does a deck need a railing if it’s less than 30 inches off the ground?

Not under the guard rule. Guards are required where the surface is more than 30 inches above the floor or grade below at any point within 36 inches horizontally of the open edge. On a sloped lot, measure down to the lowest grade within 36 inches of the edge, because that’s the number that counts.

Can I build higher than 20 or 25 feet in a View-Sensitive District?

Not without a variance. In these districts no part of the structure is supposed to extend above the height plane, and that can include rooftop guardrails and covers. Ask the city’s Planning and Development Services at (253) 591-5030 whether your parcel is in a VS-20 or VS-25 area before you design anything on the roof.

Can I put a rooftop deck on my house for a Mount Rainier view?

Sometimes. The roof structure has to carry the load, the waterproofing below the deck has to be right, and the guardrail has to fit under any height limit. Surface material matters too. We compared a rooftop project priced in porcelain pavers and in wood if you want to see how the numbers came out.

Which way should a view deck face in Tacoma?

Toward the view, but plan for the sun that comes with it. Southeast-facing decks aimed at Rainier are shaded by the house in the late afternoon. Southwest-facing decks over the bay get afternoon heat and glare and usually need some kind of shade. Northeast-facing decks over the bay stay the coolest.
