Tacoma Patio and Hardscape Permits

In Tacoma, an at-grade paver patio, walkway, or driveway generally needs no building permit, and a retaining wall needs one only when it is taller than 4 feet from the bottom of the footing or supports a surcharge. Larger jobs can still trigger a site development permit at 2,000 square feet of new or replaced hard surface or 50 cubic yards of grading. ND Brick Pavers confirms this before quoting.

That is the short version. The rest of this page is the detail I go through with homeowners before a number goes on paper, because the expensive surprises come from the parts of a project people do not think of as "construction": the gas line, the curb cut, the extra dirt, the cover over the grill. Everything below is from the City of Tacoma's own permit pages, linked at the bottom. Tacoma is its own jurisdiction. If your address is in Lakewood, University Place, Puyallup, or unincorporated Pierce County, the rules come from a different counter.

Do I need a permit for a paver patio in Tacoma?

For most backyard patios, no building permit is required. Tacoma adopts the International Residential Code exemptions through its municipal code, and the city's "What Requires a Permit" tip sheet lists sidewalks and driveways as exempt from a building permit, with a note that a separate site development permit may still be required.

The list does not use the word "patio." An at-grade paver patio is the same kind of flatwork as a walkway, and in practice it is handled the same way, but that is exactly the kind of assumption worth one call to Planning and Development Services when the project is large, raised, or attached to other work.

Three things move a patio out of the simple category:

It is raised. Once the patio sits on a retaining wall or has a drop at its edge, the wall and any guard become the permit question, not the pavers.
It is big, or part of something big. Size triggers site development review, covered next.
It is in a sensitive place. Critical areas and historic districts bring their own review, regardless of size.

When does a hardscape project need a site development permit?

This is the threshold that catches people, because it has nothing to do with height or structure. Tacoma's site development (SDEV) permit is required for:

Grading or fill of more than 50 cubic yards of material.
New or replacement of 2,000 square feet or more of hard surface.
Any project that disturbs 7,000 square feet or more of land.

Notice the word "replacement." Tearing out a cracked concrete patio and a tired asphalt driveway and replacing both with pavers is replaced hard surface. A 600 square foot patio, a 1,200 square foot driveway, and a long side walkway in the same contract can add up past 2,000 square feet without anyone noticing.

The 50 cubic yard figure matters on sloped lots. Leveling a patio pad into a hillside in the North End or along the bluffs above Commencement Bay can move far more soil than the finished surface suggests, especially once you count imported base rock. We estimate cut and fill volume during the site visit for exactly this reason.

One more condition: Tacoma's grading and clearing exemptions do not apply inside a critical area under TMC Chapter 13.11. Steep slopes, wetlands, and stream buffers can turn a small job into a reviewed one.

Crossing 2,000 square feet also pulls in the city's stormwater rules. The 2026 Tacoma Stormwater Management Manual applies to applications submitted on or after July 1, 2026. Under the 2021 manual, the city's policy memo ESD22-02 applied Minimum Requirements 1 through 5 to redevelopment that results in 2,000 square feet or more of new plus replaced hard surface. Confirm the threshold under the 2026 manual for your application date. In plain terms, expect a project that size to need a drainage plan, not just a permit number.

Do I need a permit for a retaining wall in Tacoma?

Tacoma's residential exemption covers retaining walls not over 4 feet measured from the bottom of the footing to the top of the wall, unless the wall supports a surcharge. A surcharge is any extra load on the soil behind the wall: a driveway, a slope, a structure, or a parking pad.

Two Tacoma-specific notes:

The measurement includes the buried footing and base course, so a wall that looks like 3.5 feet from the patio can measure over 4.
Tacoma's commercial exemption list says outright that a fence on a retaining wall counts as a surcharge. The residential list does not repeat that sentence, so if you plan a fence on top of a wall at home, ask before you assume it is exempt.

Tacoma's permit types page lists retaining walls under Residential Alteration and New Building permits. We cover walls across Pierce County, including how height is measured, in our separate retaining wall permit guide.

Do I need a permit for an outdoor kitchen in Tacoma?

The masonry counter itself is rarely the issue. The utilities and the roof are. Break an outdoor kitchen into its parts:

Electrical. Washington L&I states that Tacoma Power issues electrical permits and performs inspections for the properties it serves, which includes Tacoma, Fircrest, University Place, Fife, parts of Steilacoom and Lakewood, and unincorporated Pierce County south to Roy. New outdoor circuits for a refrigerator, lights, or a rotisserie need that permit.
Plumbing. Tacoma's residential plumbing permit covers new piping and sinks. An outdoor sink with a water line and a drain is plumbing work.
Gas. Tacoma's permit types page lists residential mechanical permits for heating and ventilation equipment but does not name fuel gas piping. Confirm the permit path for a gas line to a built-in grill or fire feature with Planning and Development Services before the trench is dug.
A roof or pergola. Tacoma exempts one-story detached accessory structures up to 200 square feet. A cover attached to the house, or a larger freestanding one, is a structure that needs review. Most porches and decks need a building permit, per the city's porch and deck tip sheet.
A wood-burning fireplace. Tacoma's woodstove and fireplace tip sheet requires a building permit before installing a solid-fuel appliance and requires listed appliances. It is written for heating appliances. For an outdoor masonry fireplace, ask the city which path applies.

The useful takeaway: the permit is driven by what you connect, not what you stack. A counter with a propane tank and no power can be a very different filing than a counter with a sink, a fridge, and a natural gas line.

What about raised patios, steps, and decks next to the patio?

Tacoma exempts a deck when it is 200 square feet or less, no more than 30 inches above grade at any point, not attached to the house, and not serving the required exit door. Miss any one of those and it needs a permit.

The same 30-inch figure shows up in Tacoma's guard rule: a guard is required where the drop is more than 30 inches measured vertically within 36 inches horizontally. For a raised paver patio on a wall, that is the height where an edge stops being a step and starts being a fall.

The city's porch and deck tip sheet also lists stair limits: a maximum rise of 7-3/4 inches, a minimum tread depth of 10 inches, a minimum width of 36 inches, and handrails on any set of four or more stairs. Those numbers are written for decks and porches, but they are good targets for paver steps too. Steps that follow them feel right underfoot.

Does a new driveway or curb cut need a permit?

The driveway on your lot is exempt from a building permit. The part in the street is not. Tacoma Municipal Code requires a written permit before anyone paves, alters, replaces, or excavates a sidewalk, curb, or driveway approach in a street, alley, or public place.

Smaller work, like replacing or widening a driveway approach, uses a Right-of-Way Construction (RCON) permit with a site plan and a traffic control plan. Larger work goes through a Work Order permit with civil-engineered drawings. If your paver driveway project includes a new or wider apron at the curb, that permit belongs in the schedule and the estimate.

What else can add review to a Tacoma hardscape project?

Historic districts. Tacoma has nine historic districts, including North Slope, Stadium/Seminary, and the Wedge. Inside one, exterior work that needs a permit may need design review by the Landmarks Preservation Commission. The city lists landscaping-only work as exempt, so a plain patio usually is not affected, but a porch, a covered kitchen, or a wall that needs a permit can be.
Fences. Fences up to 7 feet high are exempt from a building permit. Above that, permit.
Critical areas. As noted above, critical areas remove the grading exemptions.
Stormwater connections. Tying a patio drain or a driveway trench drain into the city system is a utility connection, not just a yard drain.

A Tacoma permit checklist before you sign anything

Use this with any contractor, including us:

Is every surface at grade, or is any part raised more than 30 inches?
Is any retaining wall over 4 feet from the bottom of the footing, or holding a driveway, slope, fence, or structure?
What is the total of new plus replaced hard surface across the whole contract? Is it near 2,000 square feet?
How many cubic yards of soil are being cut or filled, including base material?
Does the work touch the curb, sidewalk, or driveway approach?
Are there new electrical circuits, a gas line, a sink, or a roof?
Is the property in a historic district or near a steep slope, wetland, or stream?
Who is filing the permits, and is the permit fee itemized in the estimate?

If a contractor cannot answer these at the estimate, they have not looked closely enough at the job.

Frequently Asked Questions

Do I need a permit to replace an old concrete patio with pavers in Tacoma?

Usually not a building permit, if the new patio sits at grade. What changes the answer is size and dirt. Tacoma requires a site development permit for new or replaced hard surface of 2,000 square feet or more, or grading and fill of more than 50 cubic yards. A tear-out and replacement counts as replaced hard surface, so a large patio plus a driveway in the same project can cross that line.

Does a fire pit on a paver patio need a permit in Tacoma?

Tacoma's woodstove and fireplace tip sheet covers solid-fuel appliances and does not address outdoor fire pits, so ask Planning and Development Services about a built-in wood-burning unit. Separately, the Puget Sound Clean Air Agency prohibits fire pits and chimineas during a Stage 1 burn ban in Pierce County. A gas line to a fire feature is gas work and should be confirmed with the city before it is run.

Who issues electrical permits for an outdoor kitchen in Tacoma?

Tacoma Power, not the state. Washington L&I says Tacoma Power issues electrical permits and performs inspections for the properties it serves, which includes Tacoma, Fircrest, University Place, Fife, and parts of Lakewood and Steilacoom. Outside that service area, most jobsites buy the electrical permit from L&I.

Is a paver walkway exempt from permits in Tacoma?

Tacoma's residential exemption list names sidewalks and driveways as exempt from a building permit, with a note that a separate site development permit may still be required. A walkway is exempt in the same way unless the overall project crosses a site development threshold or sits in a critical area.

Do I need a permit to widen my driveway where it meets the street?

Yes, for the part in the street. Tacoma requires a written permit before anyone paves, alters, or replaces a curb, sidewalk, or driveway approach in the public right-of-way. Smaller work like driveway approach replacement is handled with a Right-of-Way Construction permit that needs a site plan and a traffic control plan.

What happens if I start a Tacoma hardscape project without a required permit?

Tacoma has a tip sheet titled Obtaining Permits to Resolve a Violation, which tells you the city has a process for after-the-fact permits. It is slower and less predictable than permitting up front, and unpermitted work can come up again during a sale. Checking first costs a phone call.
