Boise Pergolas provides pergola & patio cover in Boise, ID.
Pergolas, attached patio covers and pavilions for homes in Boise and nearby towns, built on footings and framing sized for local loads. Boise's code designs residential roofs for at least 25 pounds per square foot of snow, so a shade structure here has to carry winter weight as well as block summer sun.

Custom Pergola Design & Build in Boise
HomeAdvisor puts the average pergola at $4,253, with most projects between $2,118 and $6,433 (updated June 2026). HomeGuide lists a custom-built 12'x12' wood pergola at $4,300 to $9,350, or $30 to $65 per square foot, against $1,450 to $5,750 for a prefab kit installed on an existing base. In Boise, a freestanding pergola over 200 square feet needs a building permit and is usually treated as pole construction designed by an Idaho licensed engineer, so the size chosen at the design stage also decides the paperwork.

Patio Covers in Boise
A patio cover is a roof, usually attached to the house, over a slab or deck. HomeGuide puts a cover over an existing patio at $20 to $60 per square foot installed, with aluminum at $20 to $50, vinyl at $25 to $80 and solid wood at $60 to $120 per square foot. The City of Boise requires a permit for any attached patio cover regardless of size, because its weight is carried by the wall of the house. Wood-framed covers that stay within the city's pre-engineered limits (spans of 12 feet or less, 10 feet or less at the column line) may not need project-specific engineering.

Pavilion Construction in Boise
A pavilion has a solid roof, so it sheds rain and holds snow, while a pergola's open roof does neither. HomeGuide puts pavilion construction at $35 to $60 per square foot before foundation work, with concrete pier footings at $125 to $300 each (at least four) and a new slab at $5 to $10 per square foot. A solid roof in Boise has to be designed for at least 25 psf of snow under the city's code, which is why pavilions usually come with engineered drawings.

Pergola Materials in Boise
HomeGuide lists material-only prices per square foot at $10 to $30 for aluminum or vinyl, $20 to $40 for pine, $25 to $40 for cedar and $50 to $70 for fiberglass. HomeAdvisor puts a 100-square-foot pergola at $1,000 to $3,000 in aluminum and $2,500 to $3,500 in cedar (2026). Wood needs stain or sealer every few years; HomeGuide puts staining at $4 to $6 per square foot. Aluminum and fiberglass need less upkeep but have fewer profile choices.

Pergola Footings & Foundations in Boise
Boise City Code sets the local frost line depth at 24 inches, and the city's patio cover policy requires footings installed to frost depth and sized per its pre-engineered drawings. HomeGuide puts concrete pier footings at $125 to $300 each and a new slab at $5 to $10 per square foot. Posts set on an existing patio slab need the slab checked first: a thin slab may not carry a post load. Other cities set their own rules, so confirm the footing depth with the city that issues the permit.

Pergola Lighting & Electrical in Boise
Running wire while the frame is open keeps it hidden in beams and posts. HomeGuide puts outdoor light fixtures at $80 to $300 each, an outdoor outlet at $180 to $350 and a ceiling fan at $150 to $500 per fan. In Boise, low-voltage outdoor lighting does not need an electrical permit, while 110-volt lighting does, and the wiring must be done by a State of Idaho licensed electrician unless the homeowner does it on their own primary residence.

Shade & Louvered Roof Systems in Boise
HomeGuide prices a manual louvered roof at $45 to $110 per square foot ($6,500 to $15,800 for 12'x12'), a motorized one at $55 to $125 per square foot ($7,900 to $18,000) and a smart model with sensors at $75 to $175 per square foot. A fixed wood lattice roof costs $25 to $50 per square foot and a retractable canopy $4 to $10. When louvers close they form a roof, so ask the provider for the system's rated snow load and compare it to Boise's 25 psf minimum roof snow load.

Pergola Engineering & Permits in Boise
Boise's code uses a 20 psf ground snow load, a 25 psf minimum roof snow load and a 90 mph design wind speed. The city requires a permit for any attached patio cover and for freestanding pergolas over 200 square feet, which it usually treats as pole construction needing an Idaho licensed engineer. HomeGuide puts a structural engineer at $100 to $220 per hour and a pergola permit at $60 to $150 on average nationally; the city sets the actual fee. Meridian, Nampa and the other cities issue their own permits, and an HOA may need to approve the design first.

Pergolas for Outdoor Kitchens in Boise
When a pergola or pavilion goes over an outdoor kitchen, the grill's clearance to the roof comes from the grill manufacturer's instructions, and the post layout has to leave room for counters. In Boise, gas piping between the meter and an outdoor appliance needs a mechanical permit, and wiring for lights or a fridge needs an electrical permit. Ask the provider to show the clearances and permits in the quote.

Pergola Removal & Replacement in Boise
HomeGuide puts removing an old pergola at $150 to $700 and repairing one at $2 to $6 per square foot for paint or $4 to $6 for stain. Rotted posts, a sagging beam or a leaking ledger connection can mean a full replacement. A replacement attached cover in Boise needs a new permit, so ask the provider whether the old footings can be reused or must be replaced.
Pergola Removal & Replacement DetailsFrequently Asked Questions
How much does a pergola cost in Boise?
HomeAdvisor puts the national average at $4,253, with most projects between $2,118 and $6,433 (updated June 2026). HomeGuide lists a prefab kit installed at $1,450 to $5,750 and a custom wood pergola at $4,300 to $9,350 for 12'x12'. These are national figures: a local builder prices your project after seeing the site, the size and the permit needs.
How much does a pergola cost per square foot?
HomeGuide puts a kit installed on an existing base at $10 to $40 per square foot and a custom-built pergola at $30 to $65 per square foot. A louvered roof runs $45 to $125 per square foot, and footings, electrical and the permit are extra.
Do I need a permit for a pergola in Boise?
Per the City of Boise's residential construction guide, any attached patio cover needs a permit, and a freestanding pergola or gazebo over 200 square feet needs one too, usually with structural engineering by an Idaho licensed engineer. Height and setback limits may also apply; the city's permit line is 208-608-7070.
Do you need a permit for a freestanding pergola?
Around Boise it depends on size and city. Boise and Meridian both let a detached structure of 200 square feet or less go without a building permit, while Nampa lists covered patios as needing a permit. Setbacks still apply, so confirm with the city that covers your address.
What snow load does a pergola need in Boise?
Boise City Code 9-1B-33 sets a 20 psf ground snow load and requires roofs to be designed for at least 25 psf. An open lattice holds little snow, but a solid patio cover, a pavilion or a closed louvered roof does, so ask for the system's rated snow load in writing.
What is the difference between a pergola and a patio cover?
A pergola has an open roof of beams or slats that gives partial shade, while a patio cover has a solid roof that also keeps rain off. In Boise both need a permit when attached to the house. HomeGuide puts an aluminum patio cover at $20 to $50 per square foot.
How much does a louvered pergola cost?
HomeGuide puts a manual louvered pergola at $6,500 to $15,800 for 12'x12' ($45 to $110 per square foot) and a motorized one at $7,900 to $18,000 ($55 to $125 per square foot). Smart models with rain and wind sensors run up to $175 per square foot.
How long does a pergola last?
It depends on the material and the upkeep: wood needs stain or sealer every few years, while aluminum and fiberglass need less. Footings set to Boise's 24-inch frost line keep posts from heaving in winter. Ask the provider for the manufacturer's warranty term on the materials quoted.
Can a pergola be attached to the house?
Yes, but in Boise an attached pergola or patio cover always needs a permit, because its weight is carried by the house wall. Under the city's patio cover policy, a wood-framed cover with spans of 12 feet or less and a height of 10 feet or less at the column line may be built from pre-engineered drawings.
How deep do pergola footings go in Boise?
Boise City Code sets the frost line at 24 inches, and the city's patio cover policy requires footings to frost depth. HomeGuide puts concrete pier footings at $125 to $300 each. Other cities set their own depth, so confirm it with the city that issues the permit.
Do lights or a ceiling fan on a pergola need a permit?
In Boise, low-voltage outdoor lighting does not need an electrical permit, while 110-volt lighting and new outlets do. In Garden City, electrical permits are issued through the State of Idaho. HomeGuide puts a ceiling fan at $150 to $500 and an outdoor outlet at $180 to $350.
Which towns does this site cover?
Boise, Meridian, Eagle, Kuna, Star and Garden City in Ada County; Nampa in Canyon County; and the smaller nearby communities of Middleton, Hidden Springs and Melba, Idaho.
How It Works
- 1
Free On-Site Estimate
A local builder looks at the patio or yard, the wall the structure would attach to, the sun exposure and the setbacks, and asks how the space will be used.
- 2
Written Quote
The quote should list size, material, roof type, footings, electrical, the permit and any engineering as separate lines, so two quotes can be compared.
- 3
Permit & Build
Attached covers and larger freestanding pergolas usually need a city permit before work starts. Ask the provider who files it and for a written schedule.
- 4
Inspection & Handover
Where a permit applies, the city inspects the work. The builder then explains care for the material and hands over the manufacturer warranty papers.
Why Choose Boise Pergolas
- ✓ Free, no-obligation request. Your request goes to a local pergola or patio cover builder who calls you back about the project.
- ✓ Sized for Boise loads. Ask the builder how posts, beams and footings meet the city's 25 psf roof snow load and 24-inch frost line.
- ✓ Written quote. It should list size, material, roof type, footings, electrical, engineering and permit before work begins.
- ✓ Proof first. Ask the provider for proof of licensing and insurance before work starts.

Why Treasure Valley Homeowners Add a Pergola or Patio Cover
Summer Shade
Boise's code uses a 95°F summer design temperature for cooling. A lattice, louvered or solid roof shades a patio in the afternoon sun.
Outdoor Entertaining
A covered area over a patio, deck or outdoor kitchen gives a defined place to host, with room for lights and a fan.
Newer Homes, Bare Yards
Most homes in Meridian, Eagle, Kuna and Star were built in 2000 or later (ACS 2024 5-year).
Built for Winter
Boise's code sets a 20 psf ground snow load and a 24-inch frost line, so posts, beams and footings have to be sized for both.
Warranties: Get Them in Writing
Warranty terms depend on the provider and on the manufacturers of the materials used. Before signing, ask the provider for the written workmanship warranty and for each manufacturer's warranty (lumber, aluminum system, louvered roof, fan or lights), with what they cover and for how long. This site does not issue a warranty of its own.
