Built Around Your Life, Landscape & Style
Custom Deck Design & Construction in California
More Than a Deck — It’s Your Personal Outdoor Escape
Every Custom Deck Starts with Purpose & Precision
We don't believe in cookie-cutter builds. Every project begins with a collaborative consultation to understand how you live, entertain, and relax. From there, we tailor the deck layout, elevation, materials, and features to your property’s dimensions, sun exposure, and viewlines. Our CAD renderings allow you to see your deck before we build it—down to the last board. Whether you're building new or upgrading an existing space, we ensure every detail fits your life.
Built for Comfort, Safety & Curb Appeal
Why California Homeowners Choose Our Custom Decks
When you choose Alliance Deck Builders, you're investing in structural integrity, design excellence, and standout curb appeal. We take local code compliance, hillside setbacks, and HOA requirements into account while maximizing usable space. Each deck is designed for long-term performance and customized to elevate both your lifestyle and your home’s value.

Engineered to exceed California building codes
Style That Matches Your Home, Function That Fits Your Life
Design Expertise for Elevated Outdoor Living
From hillside overlooks in Los Angeles to narrow backyards in San Francisco, our team knows how to design around California’s diverse terrain. We build decks that enhance your views, provide shade where needed, and create effortless flow between your interior and exterior living spaces. Choose from cedar, composite, or pressure-treated lumber—and customize every detail, including lighting, staircases, railings, pergolas, and built-in seating.
Long-Term Strength Begins with Smart Framing
Structurally Engineered Decks That Last Decades
Every custom deck is framed for durability using pressure-treated joists, stainless hardware, and code-compliant footings. We account for seismic movement, water drainage, and soil conditions across California to prevent sagging, warping, and rot. Whether your site is level, sloped, or hillside, we build with the structural integrity that’s needed in wildfire zones, marine air environments, and high-traffic settings. You’ll have peace of mind knowing your deck is built to handle decades of sun, storms, and life.
