Freestanding Pergola Construction
Handis freestanding pergola construction puts a four-to-six-post Western Red Cedar timber-frame or powder-coated aluminum louvered pergola on a residential deck, patio, or backyard — no house attachment, no ledger flashing, no rim-joist through-bolt, structure stands on its own concrete-set footings — from $6,000 for an 8-by-10 freestanding cedar plan to $16,000 for a 16-by-20 freestanding cedar build. Freestanding gives placement flexibility — the pergola sits in the middle of the yard, over a freestanding patio away from the house, or as a hot-tub canopy with no wall in reach. Plans under 200 square feet usually clear the permit threshold entirely in most Seattle-area jurisdictions (confirmed for the specific address on the booking call), which removes 1 to 4 weeks of permit lead time from the schedule. The structural simplicity of a freestanding plan — no ledger, no Z-flashing, no wall-fastener detail — also makes the build slightly faster than the equivalent attached configuration once the footings have cured.

How a Freestanding Pergola Build Works
Seven sequential steps from site review through finish-detail — the actual sequence we follow on every freestanding pergola build.
Site Review and Post-Location Layout
Tech walks the deck, patio, or yard area, confirms the post locations against any septic field, gas line, water service, irrigation, or electrical conduit (811 call for public utilities, homeowner walkthrough for private lines), and validates the layout square with a 3-4-5 method against the deck edges or property lines. Confirms whether the plan falls under or over the jurisdiction's permit threshold.
Power-Auger Footings to 24-30 Inches
Power-auger every footing to 24 to 30 inches below grade with the diameter sized to the post size and load (12 to 18 inches typically). Manual post-hole digging in PNW clay is a week of labor we are not going to pass along. Four footings on standard plans (one at each corner), six on larger plans (four corners plus two mid-span supports on the long axis).
Pour Concrete with Post-Base Anchors Set in the Wet Pour
Pour ready-mix concrete around a Simpson ABA or ABU post-base anchor (cedar) or the manufacturer-specified post-base (aluminum) set plumb in the wet pour. Anchor positioning checked against a 4-foot level and a chalk line so every post lands plumb and the structure reads square against the deck or patio edges.
48-Hour Concrete Cure Between Pour and Post-Raise
Concrete cures 48 hours before the post is raised. Cure delay is fixed (not negotiable — green concrete pulls the anchor when the post load goes on). On a two-day build window we pour day one and raise day two; on a one-trip build we pre-cure the footings on a prior visit and raise on the second visit.
Raise the 6x6 Cedar Posts (or Aluminum Posts)
6x6 cedar posts (or aluminum posts on louvered systems) lifted onto the cured ABU anchors and through-bolted with the post-base hardware. Each post plumbed against a 4-foot level on two faces and braced with 2x4 cedar braces to the ground until the beams go up. Plumb verified on every post before the beams are set.
Set the Beams and Install Rafters or Louver Frame
4x8 (standard span) or 6x8 (over-12-foot span) cedar beams raised with a deck post jack and two installers, set into Simpson ZMAX post-cap hardware, through-bolted with 5/8 inch carriage bolts. Cedar rafters (2x6 or 2x8) installed with hurricane ties and concealed structural screws; on aluminum louvered, the louver frame assembled per the manufacturer manual and the louvers mounted into the frame.
Finish-Detail and Tools Off Site
Rafter tails chamfered or scalloped (cedar), post caps installed (cedar), post-base trim hiding the post-to-anchor connection. On aluminum louvered, motor commissioning per the manufacturer procedure and warranty registration filed. Tools off site at the end of the second or third day on standard plans; larger plans (12-by-16 and up) run an additional half day.
Freestanding Pergola Pricing
Final pricing depends on plan size, material (cedar timber-frame vs aluminum louvered), beam up-size requirement on spans over 12 feet, rafter spacing on cedar (24 vs 16 inches on center), and whether the plan falls over the 200-square-foot permit threshold for your jurisdiction. Plans under 200 square feet usually do not require a building permit; plans over 200 square feet require a permit pulled by Handis with the fee passing through as a named line item.

Why Handis for Freestanding Pergolas
The 200-square-foot permit threshold is the single biggest budget lever on a freestanding pergola. A 12-by-16 cedar plan at 192 square feet clears the threshold in most Seattle-area jurisdictions, avoids the 1 to 4 weeks of permit lead time, and saves the $400 to $800 permit-and-review fee. A 12-by-18 cedar plan at 216 square feet crosses the threshold and triggers the permit, the engineer-of-record sign-off on larger configurations, and the framing inspection schedule. We are honest about the permit-threshold math on the first visit — sometimes the right call is to stay just under the threshold with a 12-by-16 plan that covers everything you want covered; sometimes the right call is to cross the threshold for a 14-by-16 plan because the extra 32 square feet matters for the use case. We do not push you to cross or stay under either way; the math is yours.
Estimate
Tell us the rough footprint (length by width — a 12-by-16 measurement off the deck or patio), the material preference (Western Red Cedar or aluminum louvered), and where in the yard the pergola lands (over a deck, over a flagstone patio, in the middle of the lawn, over a hot tub). We confirm the permit threshold for your jurisdiction and review the post locations against any buried utility lines on the first visit.
Customer Reviews
Freestanding pergola reviews from real Handis customers.
12x16 freestanding cedar pergola over our flagstone patio in Magnolia — 192 square feet, just under the Seattle DCI permit threshold so no permit was needed and we saved 3 weeks of lead time. Handis power-augered the six footings, set the 6x6 posts, raised the 6x8 beams, and chamfered the rafter tails. Two summers in and the cedar is silver. Reads exactly like the inspiration photos.
10x12 freestanding cedar pergola in the corner of our Issaquah backyard — over a paver patio we already had. Under the 200 square foot threshold so no Issaquah permit. Handis dug the four footings with the power auger, ran the layout against my septic field (which I had no idea was that close to where I wanted the pergola), and built the structure two days later. Saved me a $2,000 septic-line repair callback that the wrong location would have caused.
8x10 freestanding cedar pergola over our hot tub in Kirkland. Smallest plan they build but Handis took the same care — site review against the buried hot tub electrical conduit, power-augered footings, plumb posts on the Simpson anchors, chamfered rafter tails, low-voltage LED strip in the rafters. Under 200 sq ft so no Kirkland permit. Five days from booking call to finished pergola.
16x20 freestanding cedar in our Sammamish backyard — 320 square feet so the Sammamish permit was required. Handis pulled the permit, engineer-of-record signed off on the wind-load calcs (Tiger Mountain wind exposure), and the structure went up over 3 days after the footings cured. Six posts on the long-axis configuration, up-sized 6x8 beams, 2x8 rafters at 16 on center. Largest pergola I have seen on a residential property and it reads as architecture.
12x14 freestanding cedar in our Ballard backyard — 168 square feet, no Seattle permit. Heavy clay in the lot meant manual post-hole digging would have taken a week. Handis brought the power auger, dug all four footings in an afternoon, poured the concrete, came back two days later and had the structure up by end of day two. Scalloped rafter tails, ball-top post caps, looks like furniture.
