ADU Company in Woodland Hills, CA
Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions in Woodland Hills, CA, where the housing stock and the foothill terrain create a very different build environment than flatland parts of the Valley. Many of the ranch homes here sit on lots of 10,000 sq ft or more, which sounds ideal for a detached ADU, but the minute an inspector sees a hillside property inside the Very High Fire Hazard Severity Zone, the permit conversation changes completely. We put every price in writing before work begins, and a live person answers our phone at (254) 602-5618 around the clock.
Why Woodland Hills Homes Are Different
Woodland Hills is not one building environment. It is two. The flatlands hold single-story 1950s to 1970s ranch houses on unusually large lots, often 10,000 to 15,000 sq ft, which makes a detached ADU genuinely feasible from a setback and footprint standpoint. The hillsides climbing toward the Santa Monica Mountains are a different story. A large share of those properties sits inside Los Angeles’s Very High Fire Hazard Severity Zone, the VHFZ, which the 2018 Woolsey Fire turned from a paperwork designation into something homeowners here take personally. ADUs on those lots must meet Chapter 7A fire-resistant construction standards: ember-resistant venting, ignition-resistant cladding, and Class A roofing. Flatland Valley builders who quote those jobs without checking the maps routinely lowball them by $20,000 to $35,000 on the envelope alone.
The other Woodland Hills reality is heat. This area records the highest temperatures in the LA metro, with September days pushing past 110°F and no marine layer to cool things down overnight. An ADU here needs an HVAC or mini-split system sized far more aggressively than a comparable build in Santa Monica or Culver City, and a garage conversion without serious attic insulation becomes a metal box by mid-afternoon. Older 100-amp electrical panels and aging sewer laterals are common across the original housing stock, and LADBS often requires both upgraded before an ADU gets signed off.
Our Main Woodland Hills Services
Woodland Hills homeowners most often call us about two things: adding square footage to the house they already live in, and converting underused space like garages into rentable or family-ready units. Each service has its own dedicated Woodland Hills page below.
Home Addition Contractor in Woodland Hills
Home additions in Woodland Hills usually mean building out on a ranch home’s generous lot, which is the good news. The less good news is that hillside additions can trigger the same VHFZ Chapter 7A requirements as ADUs, shifting the budget before framing even starts. We handle the full scope: floor plan work, foundation, framing, roofing, HVAC sizing that accounts for this area’s 110°F September days, and the LADBS documentation. Every addition gets a written price before work begins. Learn more on our Home Addition Contractor in Woodland Hills page.

Garage Conversion Contractor in Woodland Hills
A garage conversion in Woodland Hills is one of the fastest paths to livable space, since the shell already exists and the lot does not need to give up yard. But a 1950s or 1960s garage here typically needs real work: electrical panel upgrades from the original 100-amp service, insulation that can handle this neighborhood’s heat, and sewer lateral work depending on where the new bathroom lands. We convert attached and detached garages into proper units with permits pulled and inspections passed. See specifics on our Garage Conversion Contractor in Woodland Hills page.

ADU Builders in Woodland Hills
Building a detached ADU on a large Woodland Hills lot is often more practical here than almost anywhere else in LA, but the fire zone changes the math. Homes climbing toward the Santa Monica Mountains foothills frequently face Chapter 7A requirements that flatland Valley properties never trigger, and our job is to price that reality honestly from the first conversation, not surprise you at plan check. We work with prefab manufacturers like Cover and Dvele where they fit the lot and budget. The full breakdown is on our ADU Builders in Woodland Hills page.

What pushes a Woodland Hills quote upward is almost always the same two things: a hillside address inside the VHFZ, and an original electrical panel or sewer lateral that LADBS will not sign off on. That is exactly why we put the written price in your hands before any work starts, and why that price does not change at the door.
