Deck Installation Experts

We tell most folks that a building permit for a deck depends primarily on its height above ground:

• Decks 30 Inches or Lower: Generally, if your deck's walking surface is 30 inches or less above the ground, a building permit isn't required.

• Decks Above 30 Inches: For decks more than 30 inches above ground, a building permit is typically required with most city safety and building codes.
• Deck Rebuild: For decks that are being rebuilt a permit is generally not needed.

Our recommended choice for diverting rainwater under a deck is the Zip-Up UnderDeck System. It's specifically designed to create a water-tight barrier between the deck and the space below, ensuring that water doesn't seep through. This system is not only easy to install but also highly effective, allowing you to create a dry, usable space underneath the deck while protecting it from moisture.

While it's possible to use deck boards for fascia, fascia boards specifically designed for this purpose (from the same material as your decking) are usually better. They are thinner and more flexible, allowing them to conform to the edge of the deck more easily and provide a clean, finished look.

Composite decking is generally considered the best option because it's durable, low-maintenance, and long-lasting. Unlike wood, composite decking resists rot, insects, and moisture, which means less upkeep over time.

We highly recommend Deckorators for its superior performance, particularly in rainy environments like Portland and Vancouver. Deckorators' mineral-based composite decking is not only durable but also slip-resistant, making it an ideal choice for areas with frequent rain, ensuring safety and stability year-round.

Cedar is a great choice due to its natural resistance to rot, decay, and insects. Other options include pressure-treated lumber, which is more affordable, and hardwoods like Ipe or Teak, which are more expensive but extremely durable.

Leif recently gave an overview of the typical costs of building a deck by examining several completed projects with varying sizes, features, and levels of complexity.

1. Small Deck (100-200 sq. ft.)
   • Cost: $5,000 - $10,000
   • Features: Basic design, 6-8 inches off the ground, no stairs or handrails.
2. Medium Deck (400-600 sq. ft.)
   • Cost: $18,000 - $25,000
   • Features: 1-3 feet off the ground, few steps, some customizations like lighting or posts for string lights.
3. Large Deck (Multi-use, 8 feet off the ground)
   • Cost: $30,000 - $40,000
   • Features: Glass railings, stairs to ground, suitable for dining and lounging.
4. Very Large Deck (1,000+ sq. ft., high off the ground)
   • Cost: $80,000 and up
   • Features: Engineering and permitting required, large footings, multi-levels, waterproofing, multiple features such as hot tubs, outdoor kitchens, and large staircases.

These prices offer a range based on square footage, complexity, and added features, and can vary depending on location and specific material choices.
