Give your Winnetka backyard a shady place to unwind with a professionally engineered, ready-to-assemble wood or composite deck kit, delivered curbside across the West San Fernando Valley. Framing, decking, footings and hardware are included, so a drill is the only tool you need.
A search for “deck builders near me” in Winnetka pulls up crews from all over the Valley, and many are booked out once the weather warms up. Compare the three ways to add a deck to a typical Winnetka single-story home, from hiring an installer to assembling a DIY deck kit.
A licensed West Valley contractor takes care of design, LADBS paperwork, footings, framing and cleanup. It makes sense for raised, attached or covered decks and complex layouts around a pool. Verify the CSLB license and compare written quotes.
Pick up lumber and hardware from a Valley supplier and handle the design, span tables, layout and every cut yourself. It works for experienced builders who don’t mind long days of cutting in the summer heat.
Smart ChoiceProfessionally engineered DIY deck kits in 15 wood and 9 composite sizes, delivered to your Winnetka driveway with labeled components, Tuff Block footings and hardware. Build it over a couple of cool mornings with a drill, or hire local help.
I am far from a handyman but the wife wanted a deck in the backyard and I couldn’t see myself dishing out $20,000 for someone to come build it for us. I ended up seeing an ad for this company and was blown away by the price and ease of install. 2 of our neighbours ended up ordering as well!

Winnetka sits in the West Valley, well inland from the coast. That means hotter summers, cooler winter nights and stronger Santa Ana winds than much of Los Angeles, and no snow to plan around. Factor in all three when you pick materials and a spot for your deck.
Built for hot West Valley summersSummer afternoons in the West Valley regularly top 90°F and often reach 100°F. Place the deck where it gets afternoon shade, or plan for an umbrella or shade sail.
Constant sun dries and grays wood. Seal pressure-treated decking every one to two years. If you choose composite, lighter Amazon Gray stays a little cooler than darker tones.
Rain comes in a handful of winter storms, while lawn sprinklers soak the ground all year. Slope soil away from the house and keep spray heads off the framing.
Dry offshore gusts funnel through the Valley in fall and winter. Store cushions and umbrellas on wind days, and check the CAL FIRE map if you live near the hills.

An A-DIY deck may be installed over sloped or uneven ground by adjusting the supporting post heights to establish a level deck surface.
Supported configurations may be elevated to approximately 40 inches using the appropriate posts, foundations and bracing.
Depending on the height and configuration, the project may also require:
Depending on the property, configuration and local approval, suitable systems may include:
Because Winnetka is part of the City of Los Angeles, deck permits follow LADBS rules and the LA Municipal Code. Height, attachment to the house, a roof cover and setbacks decide whether you need one. Use the quick check, then confirm with LADBS.
Rule of thumb: attached decks, covered decks and decks more than 30 inches above grade usually need an LADBS building permit.
General guidance for Winnetka-area decks
*LAMC Section 91.106.2 exempts platforms and walks no more than 30 in. above grade and not over a basement or story below. Zoning setbacks and any electrical or plumbing work still need to follow city rules.
LADBS Van NuysWinnetka has no separate city government. Permits are issued by LADBS, online or at the Van Nuys office at 6262 Van Nuys Blvd., which serves much of the San Fernando Valley.
West ValleyCanoga Park, Reseda, Woodland Hills, West Hills, Tarzana and Chatsworth are also LA city neighborhoods under LADBS. Calabasas and Hidden Hills, just to the southwest, are separate cities with their own building departments.
CaliforniaLADBS enforces the California Residential Code (Title 24, Part 2.5) with LA amendments. Hillside lots in mapped fire hazard zones also follow state wildfire construction standards.
Confirm zoning, setbacks and any easements so the deck fits where you want it.
Mark the deck’s size, height and distance to property lines. A-DIY engineering diagrams can help.
Submit online or visit the LADBS Van Nuys office.
Schedule any inspections your permit requires, then enjoy the deck.
Our deck specialists can help you plan size, height and placement before you apply.
Yes. Engineering diagrams for applicable A-DIY configurations show dimensions, structural layout, beam and joist sizes and post locations to support your application. Your department may still ask for a survey, site plan or stamped documents.
