Comparison
Pergola kit vs. professional installation
A kit is cheaper up front: louvered kits list for about $1,000–$10,000, and a contractor-assembled kit on an existing slab runs $10–$40 per square foot. But kit prices leave out footings, permits, electrical and labor, and in Arizona anyone you pay to build it needs an ROC license once the job reaches $1,000 or needs a permit.
In the Phoenix metro: aluminum pergolas from about $5,500, with a written quote before any work. Installation is done by a licensed Arizona contractor. Phoenix, Scottsdale, Mesa, Gilbert, Chandler. Call (602) 557-3625
Is it cheaper to buy a pergola kit or have one built?
| Option | Typical price | What’s left out |
|---|---|---|
| Louvered pergola kit, self-installed | $1,000–$10,000 | Footings, permits, electrical, labor, engineering |
| Kit assembled by a contractor on an existing slab | $10–$40/sq ft ($1,450–$5,750) | Footings, permits and electrical may be extra |
| Custom-built pergola, national | $30–$65/sq ft | Usually a full scope |
| Louvered pergola, installed in Phoenix | $12,000–$34,000 for about 12×12 | Electrical and permits often quoted separately |
How long does it take to install a pergola kit?
Most prefab kits take 1–2 days with two people; small bolt-together aluminum kits can go up in a day, and kits on new concrete footings need extra time for the concrete to cure before the posts go on.
Arizona rules that apply to kits
- Permits still apply. A kit follows the same rules as a custom build: detached, unwired and under 200 square feet usually skips the permit in Phoenix, Scottsdale, Mesa and Gilbert; Chandler requires one for any open-air ramada.
- Engineering. A pre-engineered kit with documentation from a licensed design professional may not need separate engineering, but a permit is still likely if it’s over the exemption.
- Licensing. If you pay someone to build it, Arizona requires an ROC-licensed contractor once the job, labor and materials together, reaches $1,000 or needs a permit.
- Wiring. Motorized kits need power, and electrical work needs a permit at any size.
