Licensed Under CSLB 757470, Building in West LA Since 1998
Eli Kaspi founded Pure Builders in 1998. The company has never taken on small remodels — only large-scale residential construction that requires full permit sets.
A Residential Construction Company Based in Calabasas
Pure Builders Inc is a general building contractor based in Calabasas, California, focused on large-scale residential construction. The company builds ADUs, custom homes, structural additions, and whole-house renovations. Every project type the company accepts requires a full permit set, structural engineering coordination, and LA County Building & Safety oversight.
Pure Builders Inc operates under CSLB License 757470 — the California Contractors State License Board credential that authorizes the work the company performs. That license has been active and continuous since the company's founding. The three geographic markets Pure Builders serves — Westside Los Angeles, Malibu, and the Conejo Valley — have remained the same since 1998.
Pure Builders has a defined scope and 28 years of project history inside it.

Founded in 1998 by Eli Kaspi — Built for Full-Permit Projects
Pure Builders Inc was founded in Calabasas in 1998 by Eli Kaspi, who remains the company's Founder and CEO today. The founding principle was specific: focus on large-scale residential construction that requires full permit sets, structural engineering coordination, and multi-trade sequencing. That principle hasn't changed. The company has not expanded into cosmetic remodeling, small kitchen jobs, or work that falls below the complexity threshold that defines its project model.
A 28-year operational record means Pure Builders has pulled permits, managed corrections, passed inspections, and delivered completed projects in this geography across multiple shifts in California ADU law, LA County plan-check systems, and local building-code cycles. The company navigated the AB 2221 legislative changes from an already-active position — not as a firm entering the ADU market for the first time.
Eli Kaspi built the company on a single geographic and service focus. Westside Los Angeles, Malibu, and the Conejo Valley aren't an expansion strategy — they're the original territory. The Calabasas office at 23966 Craftsman Rd has served as the dispatch and operations hub throughout: the same address, the same service markets, the same license.
CSLB License 757470 — What It Covers and How to Verify It
The CSLB — California Contractors State License Board — is the state agency that licenses and regulates construction contractors in California. A Class B General Building Contractor license authorizes the holder to manage and perform construction projects involving two or more unrelated building trades. That classification covers every project type Pure Builders accepts: ADU construction, custom-home new construction, structural room additions, and whole-house renovation.
Any homeowner can verify the license status, classification, bonding, and insurance information independently at cslb.ca.gov. Enter License 757470 in the license-check tool; it's listed under the company name Pure Builders Inc.
A license confirms the holder has met California's examination and application requirements for the classification, carries the required contractor's bond, and maintains the insurance coverages the CSLB requires for active licensees. The company's 28-year operational record in this geography provides the project history that a license number alone cannot convey.
A 30-Person Crew Structured for Multi-Site Delivery
Pure Builders maintains a 30-person crew dedicated to large-scale residential construction across multiple active job sites. That crew size is intentional. A detached ADU, a ground-up custom home, or a structural addition on an occupied residence requires parallel capacity: permit submissions move independently of construction, and inspection scheduling at one site doesn't pause work at another. The structure lets the company keep active projects running across Westside LA, Malibu, and the Conejo Valley without delays from crew rotation between jobs.
Every project has a designated project lead who manages day-to-day site operations, subcontractor scheduling, and inspection coordination — the homeowner's primary point of contact during the construction phase. Eli Kaspi, as Founder and CEO, remains engaged at the principal level on every active project. That is a structural feature of how the company operates.
Where specialty trade work requires licensed trade contractors — electrical, plumbing, HVAC — Pure Builders coordinates licensed subcontractors who hold current California state licenses in their respective trades and have established working relationships with the company.
The Standard Pure Builders Holds To — and Why Small Jobs Fall Outside It
Pure Builders does not take on small remodeling jobs — a deliberate feature of the company's project model, not a capacity limitation.
Large-scale residential construction — the kind that requires full permit sets, structural engineering sign-off, soils reports, multi-trade sequencing, and months of LA County Building & Safety oversight — demands a different operational structure than cosmetic remodeling. Maintaining a dedicated focus on complex, permitted work keeps the crew, project-management systems, and subcontractor network aligned to one type of project.
Site Assessment to Certificate of Occupancy
Site Assessment
An on-site, technical evaluation of the parcel, existing structures, and site conditions — the factual baseline for everything that follows. Not a sales meeting.
Scope & Cost Framework
Only after the baseline exists do scope discussions, cost frameworks, and design coordination begin — grounded in the parcel's real, site-specific variables.
Design & Engineering
Architectural drawings, structural engineering, soils where required, and Title 24 — coordinated into a permit-ready plan set for the relevant jurisdiction.
Permitting
Submission to LA County Building & Safety (or the correct jurisdiction), correction responses, and approval — managed by the team that prepared the set.
Construction
Foundation, framing, MEP rough-in, insulation, and finishes across multiple active sites — run by a designated project lead with parallel crew capacity.
Inspections & Handover
Each phase passes LA County inspection before the next proceeds, through final sign-off and the Certificate of Occupancy that closes the permit.
Every Project Starts With a Site Assessment — Not a Sales Meeting
Every Pure Builders project begins with a site assessment — an on-site evaluation of the parcel, the existing structures, and the site conditions that will shape the project. It's a technical evaluation, not a sales meeting. The findings — parcel conditions, existing utility locations, lot-coverage calculations, soil conditions where relevant, and any permit history on the property — form the factual baseline for every conversation that follows.
Pure Builders does not begin scope discussions, cost frameworks, or design coordination until that baseline exists. A homeowner who reaches out with a clear project idea but no existing drawings is in the right place — the site assessment converts a project concept into a set of real, site-specific variables. That is where the work starts.
Throughout construction, the designated project lead maintains direct communication with the homeowner on schedule status, inspection timing, and any coordination required with LA County Building & Safety. The homeowner is not separated from the project by layers of administrative staff.
Westside Los Angeles, Malibu & the Conejo Valley
Pure Builders actively serves three geographic markets from the Calabasas office — all within regular site-visit and dispatch range.
Westside Los Angeles — Pacific Palisades, Brentwood, Santa Monica, Culver City, and surrounding areas — is one of three primary markets. Malibu is the second: a coastal city that operates its own permitting authority and Local Coastal Program, the most regulatory-complex of the three, and one the company has built in since 1998. The Conejo Valley — Thousand Oaks, Westlake Village, Agoura Hills, and Oak Park — is the third, dispatched directly from the Calabasas office at the geographic center of the service area.
Questions Homeowners Ask About Working With Pure Builders
What does it mean that you're licensed under CSLB 757470?
It means Pure Builders is issued and regulated by the California Contractors State License Board. License 757470 is an active Class B General Building Contractor credential — publicly searchable, bonded, and insured — that authorizes projects involving two or more unrelated building trades. It has been active and continuous since 1998, and you can verify it yourself at cslb.ca.gov.
What kinds of projects does Pure Builders take on?
Large-scale residential construction only: new custom homes, ADUs (detached, garage conversion, multi-family and single-family zone), structural additions and room expansions, and whole-house renovation. Every project involves full permit sets, structural engineering, and LA County Building & Safety oversight. Small cosmetic remodels fall outside the company's model — by design, not capacity.
Do I need drawings or plans before I reach out?
No. A homeowner with a clear project idea but no drawings is in the right place. The first step is a site assessment that converts the concept into real, site-specific variables — parcel conditions, utility locations, lot coverage, soils where relevant, and permit history. That baseline shapes every conversation that follows.
Who is my point of contact during construction?
A designated project lead manages day-to-day site operations, subcontractor scheduling, and inspection coordination, and is your primary contact throughout construction. Eli Kaspi, as Founder and CEO, stays engaged at the principal level on every active project. You're not separated from the project by layers of administrative staff.
How does the 30-person crew affect my project?
It provides parallel capacity. Permit submissions move independently of construction, and an inspection at one site doesn't pause work at another. That structure lets Pure Builders keep active projects running across Westside LA, Malibu, and the Conejo Valley without delays from rotating a single small crew between jobs.
What areas do you serve?
Three markets from the Calabasas office: Westside Los Angeles (Pacific Palisades, Brentwood, Santa Monica, Culver City), Malibu, and the Conejo Valley (Thousand Oaks, Westlake Village, Agoura Hills, Oak Park). All three are within regular site-visit and dispatch range from 23966 Craftsman Rd.
Ready to Work With Pure Builders?
The first step is a site visit — not a phone consultation or a budget-qualification call. Call 888-240-5955 or email info@purebuildersinc.com to schedule a site assessment covering the parcel's physical conditions, existing structures, and any site constraints. Drawings aren't required; your property address, any prior permit records, and a description of what you want to build are enough to start.
