Fast, Reliable ADU Builders Across Calabasas
Building an ADU in Calabasas means navigating two separate approval tracks: the city’s permit process and your HOA’s architectural review committee. We handle both, and we file them at the same time so your project never sits half-permitted while a design board debates stucco color. Our crews work throughout Calabasas, from The Oaks to the gated communities off Mulholland Highway and along Las Virgenes Road. If you’re considering a detached ADU, garage conversion, or junior unit, call (254) 602-5618 and we’ll walk you through what your specific lot and HOA will actually require.
Why Lodgewick ADU Builders Is Calabasas’s Preferred ADU Builders Company
Since 2010, Lodgewick has been the ADU arm of the Kingswell family of home-service companies. Russ Delmar leads our build practice, and he’s spent enough time in Calabasas gated communities to know which architectural committees ask for tile roof profiles, which ones demand matched stucco color, and which ones will reject a modern flat-roof design on sight. That local familiarity is the difference between a permit that sails through and a packet that bounces back three times.
Our Calabasas customers consistently point to two things in their feedback: the written price they received before any work started, and the fact that we came back when a detail needed adjusting. The 365-Day Done Right Promise is not a slogan. It’s a written guarantee on every project. If something isn’t right within a year of completion, we return and make it right, free of charge. That matters especially in Calabasas, where HOA-mandated finishes and WUI fire-hardening details leave room for honest mistakes. Ours get fixed.
We answer calls with a live person, 24 hours a day. When you’re mid-build and your architectural committee requests a revision to your driveway treatment, you reach a human who knows your project, not a voicemail.
ADU Contractor in Calabasas
The role of an ADU Contractor in Calabasas goes well beyond framing and drywall. Here, the contractor is the one who assembles the architectural submittal packet for the HOA review board, specifies Chapter 7A fire-hardening materials for the Very High Fire Hazard Severity Zone, and sequences the whole project so city inspections and HOA approvals don’t leave you paying interest on a shell with no roof. A typical custom-built detached ADU in Calabasas runs $350 – $450 per square foot. A garage conversion lands closer to $180 – $275 per square foot, though HOA-mandated facade retention can push that higher.
What We File and When
We file the city ADU permit application and the HOA architectural submittal concurrently. The city’s state-mandated timeline can issue a permit in weeks. The HOA committee, which may meet only monthly, sets its own pace. Filing both on day one means the HOA clock starts running while the city review is already underway, not after.
Sequencing Around the Committee
We never start framing until both approvals land. That sounds obvious, but it’s the single most common mistake we see from general contractors who don’t work in Calabasas regularly. They pull the city permit, start the foundation, and then discover the HOA wants a different tile roof profile. Now the job is paused, the committee doesn’t meet for another three weeks, and the homeowner is stuck. We plan for the committee’s calendar from day one.
ADU Design in Calabasas
ADU Design in Calabasas is not a purely aesthetic exercise. It’s a compliance puzzle with three interlocking pieces: the HOA’s architectural compatibility requirements, the city’s WUI fire-hardening standards, and the physical constraints of your lot. A design that ignores any one of them will not get built. Our design process starts with a review of your HOA’s CC&Rs and any published architectural guidelines, then layers on Chapter 7A requirements, then works within your setback and lot-coverage limits.
Materials That Get Approved
In Calabasas gated communities, we find that classic materials with proven fire ratings get through review with far fewer revisions. Clay or concrete tile roofing in profiles that match the main residence. Stucco or James Hardie fiber-cement siding in colors drawn from the existing home’s palette. Wrought-iron or solid wood details rather than modern steel cable. These choices satisfy both the architectural board and the fire marshal, which is the whole game in Calabasas.
The Submittal Packet
Our design team assembles the full packet: elevation drawings showing the ADU’s roofline against the main residence, material boards with physical samples, a landscape plan showing screening from the street, and written specifications for every Chapter 7A element. We present it to the committee ourselves. When revisions are requested, we turn them around within days, not weeks, so you don’t lose another monthly meeting cycle.
Trusted Brands We Service in Calabasas
We work with established prefab and panelized manufacturers, including Cover, Dvele, and Mighty Buildings. For Calabasas specifically, we also coordinate directly with James Hardie for fiber-cement siding that meets both HOA color-match requirements and ember-resistance standards. Our relationship with these manufacturers means we can get spec sheets, fire-rating documentation, and material samples quickly when your architectural committee asks for them. That speed matters when a monthly meeting is the bottleneck on your project’s timeline.
Common ADU Builders Problems We See in Calabasas Homes
- Sequential filing stalls the project for months. A contractor pulls the city permit first, waits for the HOA architectural review, and the permitted ADU sits as an empty shell on a gated community lot while the committee meets monthly. We file both concurrently so the clocks run at the same time.
- Non-compliant finishes trigger endless revisions. Proposing a modern flat roof or smooth stucco in a community like The Oaks of Calabasas restarts the monthly review cycle from scratch. Matching the main residence’s tile roof profile and stucco color from the first submittal is how projects actually move.
- Missing Chapter 7A detailing forces rebuilds. Standard attic vents, non-rated wall assemblies, or single-pane windows get flagged during the Very High FHSZ inspection that Calabasas enforces after the Woolsey Fire. Rebuilding a wall assembly after framing is far more expensive than specifying it correctly on day one.
- Garage conversions that ignore CC&R facade rules. Many Calabasas CC&Rs require the original garage door appearance even when the space becomes living area. We install faux garage doors and matching architectural trim so the conversion passes HOA review without sacrificing interior comfort.
Pricing for ADU Builders in Calabasas, CA
A detached custom ADU in Calabasas typically runs $350 – $450 per square foot, including design, permits, materials, and labor. A garage conversion lands at $180 – $275 per square foot. Prefab ADUs from manufacturers like Cover or Dvele range from $250 – $400 per square foot installed, depending on site preparation and the level of HOA-driven customization required. The Calabasas premium over flatland San Fernando Valley pricing comes from two places: Chapter 7A fire-hardening materials (Class A roofing, ember-resistant vents, one-hour wall assemblies) and the HOA architectural review cycles that add time and revision labor to every project. We give you a written price before any work starts, and that price does not change at the door. Call (254) 602-5618 to schedule your free estimate.

FAQs About ADU Builders in Calabasas
Yes. While the city of Calabasas must issue a decision on an ADU permit within state-mandated timelines (typically 60 days), the HOA architectural review board in The Oaks and other gated communities runs on its own monthly meeting schedule. Revisions to stucco color, tile roof profile, or driveway treatment can each cost you another monthly cycle. In practice, HOA review adds three to six months to a Calabasas ADU project. We file the HOA submittal concurrently with the city permit so that clock starts running immediately. Call (254) 602-5618 if your committee is already reviewing a submittal and you need help with revisions.
The cost difference is driven by Chapter 7A fire-hardening requirements. Calabasas sits in a Very High Fire Hazard Severity Zone, established after the 2018 Woolsey Fire burned directly through the city. ADUs here must use Class A fire-rated roofing, ember-resistant vents, dual-pane windows, and one-hour exterior wall assemblies. Those materials add roughly $15 – $35 per square foot compared to a flatland valley city a few miles east where none of those standards apply. The HOA design review process also adds labor hours for submittal preparation, material sampling, and revision work. This is not contractor markup; it’s the cost of building to Calabasas’s actual code and community standards.
Yes. Under California state law, an HOA cannot prohibit an ADU outright, but it can require design compatibility with the main residence and the community’s architectural character. Many Calabasas CC&Rs specifically require that a converted garage maintain its original facade appearance. That means installing a faux garage door that looks operational from the street but functions as a fixed wall on the interior, plus matching architectural trim. In The Oaks of Calabasas, we recently completed a 620-square-foot garage conversion with exactly this requirement, paired with a Class A fire-rated tile roof profile and ember-resistant vents. The HOA approved it on the first submittal because we didn’t fight the requirement; we designed to it from the start.
We do. Our team prepares and files the city ADU permit application and the HOA architectural submittal packet as part of the project scope. That includes elevation drawings, material boards, landscape screening plans, and Chapter 7A compliance specifications. We present to the architectural committee on your behalf and manage any revision requests. You don’t need to attend a single meeting or write a single letter. For exact pricing on your specific project, call (254) 602-5618 and we’ll give you a written estimate.
We sequence the project so no work that could be invalidated by HOA or fire-safety review begins before approvals are in hand. Site surveys, soil testing, and design work happen immediately. The city permit and HOA submittal are filed concurrently on day one. We order materials with long lead times, like Class A tile roofing and ember-resistant vents, while both reviews are pending, so we’re ready to move the moment approval lands. Framing starts only after both the city permit and the HOA approval are in hand. This approach costs a few weeks of waiting at the front end but prevents the far more expensive problem of a permitted shell sitting untouched while a monthly committee meeting comes and goes. In The Oaks of Calabasas, we started framing on a garage conversion only after both approvals landed, and the project finished without a single stop-work delay.
