Thirty Crew Members. One Geographic Focus. One Project Category.
Pure Builders Inc is a residential construction company based in Calabasas, California. Founded in 1998 by Eli Kaspi, the company has spent more than 25 years building ADUs, custom homes, structural additions, and whole-house renovations across Westside Los Angeles, Malibu, and the Conejo Valley. Every project is permitted through LA County Building & Safety or the applicable local authority — none of them are small remodels.
The company holds CSLB License 757470, active and verifiable at cslb.ca.gov. It covers the full scope of general building contractor work: new construction, structural additions, ADU builds, and permitted renovation projects.
ADU Construction, Custom Homes & Structural Additions
Pick a category, then hover a service to preview it. Every item requires a full permit set, structural engineering, and LA County Building & Safety oversight — delivered under one dedicated project manager.
Founded in 1998. Licensed Under CSLB 757470. Still in Calabasas.
Twenty-five years in one geography is a project record, not a marketing line. Pure Builders has worked through multiple rounds of California ADU legislation — AB 2221, AB 976, SB 9 — and every LA County plan-check iteration since the late 1990s.
That continuity means the team knows how the unincorporated LA County permit system works in practice: which correction items appear most on first submissions, and the difference between a grading condition that needs a separate Public Works permit and one that doesn't.
The geography matters as much as the years — the Malibu Local Coastal Program, hillside grading conditions north of the 101, and the jurisdictional split between the City of Calabasas and unincorporated county. CSLB 757470 is a Class B General Building Contractor license, verifiable at cslb.ca.gov.
Talk Through Your ProjectSpecialization Is a Structural Decision, Not a Marketing Position
Pure Builders doesn't take on small remodels — no kitchen updates, no bathroom refreshes, no cosmetic work. Large-scale construction requires different infrastructure: a 30-person crew running across multiple active sites, established licensed trade partners on a coordinated schedule, and direct familiarity with the LA County plan-check and inspection cadence.
Every crew member who shows up to your site has done this work before, at this scale, in this geography. Every permit submission goes through a team that has navigated the correction cycle many times over. That consistency is what a crew focused entirely on large-scale work produces.
A Clear Path from Site Assessment to Certificate of Occupancy
1 — Site Assessment
The first step is a site visit, not a budget-qualifying phone call. We identify parcel conditions, existing structures, utility stub locations, and site constraints that shape the design and permit pathway. A property address and a description of what you want to build is enough to schedule one.
Westside Los Angeles, Malibu & the Conejo Valley
Three distinct regulatory markets, one office in Calabasas — direct access to all three without extended mobilization for site visits, inspections, and subcontractor staging.
Westside Los Angeles
The coastal and near-coastal section of LA County. Projects here typically fall under City of Los Angeles jurisdiction, with plan check submitted through LADBS — a system we navigate as part of regular project delivery.
Malibu
Governed by the Malibu Local Coastal Program, which requires a Coastal Development Permit for most new construction in the coastal zone. ESHA overlays affect placement, and CalFire Chapter 7A fire-resistive standards apply throughout — the most layered of our three markets.
The Conejo Valley
The inland region west of the Santa Monica Mountains. Addresses fall under unincorporated LA County or Ventura County depending on the parcel — we confirm jurisdictional routing at the start of every project. Expansive clay soils require geotechnical investigation before foundation design.
