ADU Company in Calabasas, CA
Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions in Calabasas, where the real work starts long before framing begins. The city’s HOA architectural review boards and Very High Fire Hazard Severity Zone rules shape every project here more than in almost any city in Los Angeles County. If you’re weighing an ADU on your Calabasas lot, call (254) 602-5618 and we’ll walk you through what actually applies to your street, your HOA, and your budget.
Why Calabasas Homes Are Different
Calabasas is dominated by 1980s to early-2000s luxury tract homes inside master-planned gated communities. Lots tend to be larger, and most homes have three-car attached garages, which is why garage conversions are the most common ADU path here. But the city carries a dual compliance burden that neighboring flatland Valley cities simply don’t have. First, communities like The Oaks of Calabasas have active architectural review boards that, while legally unable to prohibit an ADU under California state law, can require full design compatibility with the main house. That often means matched roofing profiles, specific stucco textures, and even faux garage doors on a converted garage so the street-facing facade looks unchanged.
Second, Calabasas sits inside a Very High Fire Hazard Severity Zone, hardened by the 2018 Woolsey Fire that burned directly through the city. Every new ADU structure must meet California Building Code Chapter 7A ignition-resistant standards: Class A fire-rated roofing, ember-resistant vents, dual-pane windows, and one-hour exterior wall assemblies. Those requirements add real cost per square foot compared to cities a few miles east. The HOA clock and the fire code are the two things that define a Calabasas ADU project, and we plan around both from the first site visit.
Our Main Calabasas Services
Most Calabasas homeowners call us for one of three jobs: an addition, a garage conversion, or a detached ADU. Each has its own page here because the pricing, permitting path, and site conditions are different enough to warrant separate detail.
Home Addition Contractor in Calabasas
A home addition in Calabasas usually means extending into an existing side or rear setback on a larger lot, often to add a primary suite, a family room, or a second-story wing. HOA design review applies to additions just as firmly as to ADUs, and the Chapter 7A fire code governs any new exterior wall assembly. We handle the structural engineering, the HOA submittal package, and the build itself under The Kingswell Guarantee: a written price before work starts, a defined arrival window, and a written guarantee on the finished addition. See Home Addition Contractor in Calabasas for pricing and the full scope.
Garage Conversion Contractor in Calabasas
With three-car garages on nearly every tract lot, the garage conversion is the single most common ADU pathway in Calabasas. The catch here is that many HOA CC&Rs require the converted garage to keep its original facade look, which often means installing a faux garage door or matching architectural details even though the interior is finished living space. We’ve worked through those design review conditions repeatedly and know how to package a submittal that passes committee on the first or second round. Full detail is on the Garage Conversion Contractor in Calabasas page.
ADU Builders in Calabasas
A detached ADU in Calabasas means building a small house, a lodge on your larger property, that must pass both the city’s fire hardening rules and the HOA’s design compatibility review. We work with prefab manufacturers including Abodu, Cover, and Dvele where the lot and access allow, which can compress the on-site build time significantly even if the HOA committee still runs on its own monthly clock. The complete breakdown, including unit types and cost ranges, is on the ADU Builders in Calabasas page.

What pushes prices up in Calabasas specifically is the fire zone. Class A roofing, ember-resistant vents, dual-pane windows, and one-hour exterior wall assemblies add roughly 8 to 15 percent over a comparable flatland Valley build. HOA-required facade matching, such as faux garage doors or matched stucco texture, adds another line item. Our written price covers all of it before work starts, and we do not change the number at the door.

We prepare the submittal package to pass review with minimal back-and-forth. Call (254) 602-5618 and we’ll map your specific timeline.
