IBA Builders handles permits and construction under one contract — you don’t need a separate permit expediter.
IBA Builders manages both under a single contract. One team handles your architectural drawings, LADBS submittal package, plan check responses, and the physical build. You don’t coordinate between a permit service and a construction crew. Every document that goes to the city comes from the same licensed contractor building the project — CSLB License #1074505.
IBA operates with a 10-person team based out of Sherman Oaks. The team size is intentional — it allows IBA to run multiple active projects across LA County without spreading field oversight thin. Itamar Assulin and the IBA Builders team stay involved at the project management level on every engagement, not just during the initial conversation.
The first step is a site visit and scope conversation. You don’t need finalized plans or a budget number before reaching out. The initial visit covers your property and your goal — lot dimensions, existing structures, what you want to build, and what the site can realistically support. An estimate follows once the scope is clear. For a sense of what goes into that estimate, see our overview of ADU construction costs in LA.
IBA Builders serves the full LA County territory — incorporated cities like Burbank, Culver City, Long Beach, and the City of Los Angeles, as well as unincorporated county areas. The Sherman Oaks office puts the team within reach of projects from the San Fernando Valley to the South Bay. If your property is in LA County, IBA can take the project.
CSLB License #1074505 is IBA Builders’ active California contractor’s license — verifiable in under two minutes at cslb.ca.gov.
A CSLB license — issued by the California Contractors State License Board — is the state credential that authorizes a contractor to legally perform construction work in California. It is required for any residential project valued over $500. IBA Builders holds License #1074505. To verify it yourself, verify any contractor license at cslb.ca.gov, enter the license number, and confirm the status, classification, and bond information directly. If you’d like to understand what the LADBS permit process actually involves, that detail is covered on the permit process page.
Yes. IBA Builders carries general liability insurance and workers’ compensation insurance. General liability insurance — coverage protecting against property damage or injury claims arising from construction work — means a covered loss doesn’t become your personal financial problem. Workers’ compensation insurance covers IBA’s employees if someone is injured on your property during a project. When a properly insured, CSLB-licensed contractor is on site, the homeowner is shielded from personal liability for on-site worker injuries.
Itamar Assulin is the owner of IBA Builders. He is involved at the project management level on active construction engagements — not just during the estimate conversation. IBA was founded in 2020 with Itamar as the operating principal, and that structure hasn’t changed. If you have a question about how your project is running, Itamar is the person you’re reaching. IBA also provides full ADU permit services in LA County, covering everything from LADBS submittal packages to plan check responses under one contract.
IBA Builders builds detached ADUs, attached ADUs, garage conversions, and JADUs — all under one CSLB license.
A JADU — Junior Accessory Dwelling Unit — is a unit created entirely within the footprint of an existing primary residence, capped at 500 sq ft. State law requires the property owner to live on-site in either the JADU or the primary home. An ADU (Accessory Dwelling Unit) can be detached, attached, or converted from a garage, and carries no owner-occupancy requirement or 500-sq-ft cap. The entrance rules also differ: a JADU may share an entrance with the main home, while a standard ADU requires its own independent entrance. For the full conversion process, see the JADU Conversion page.
Yes — California state law limits what your HOA (Homeowners Association, a private organization governing a residential community through CC&Rs, or Covenants, Conditions & Restrictions) can do to block ADU construction. State ADU law overrides CC&R provisions that would otherwise prohibit building an ADU on your lot. Your HOA may still impose design and aesthetic conditions — exterior materials, paint color, or roof pitch — that you will need to navigate. The authority to block the ADU outright is gone under current California law, though design-related CC&R conditions may still apply. IBA reviews any HOA design conditions as part of the pre-permit process.
IBA builds all three primary ADU configurations. A detached backyard ADU is a standalone structure in the backyard, built on its own foundation. An attached ADU shares at least one wall with the primary home. A garage conversion ADU transforms an existing attached or detached garage into a habitable unit. Each type carries different structural requirements, setback rules, and permit implications.
IBA’s scope covers ADU construction, custom home building, home extensions, room additions, garage construction, kitchen remodeling, bathroom remodeling, full house remodels, patio and outdoor space construction, pergola installation, pool construction, and concrete driveway work. IBA does not take standalone roofing-only, flooring-only, or painting-only projects. If your project involves a full remodel, an addition, or new construction, IBA is likely the right fit. Single-trade repair jobs fall outside the scope of what IBA builds.
An LA County ADU project typically runs 12 to 18 months from first call to move-in.
The full project arc covers four phases: design and pre-permit preparation, LADBS plan check and permit issuance, active construction, and final inspection leading to a Certificate of Occupancy — the official document confirming a structure is legally habitable. Design and permit preparation typically runs 2 to 4 months. Construction for a detached backyard ADU generally takes 4 to 6 months once permits are in hand. Final inspection and sign-off adds several weeks. A realistic window from first conversation to move-in is 12 to 18 months for most LA County ADU projects, with simpler garage conversions sometimes running shorter. For a detailed breakdown of the permit phase specifically, see the LADBS ADU Permit Process page.
A plan check correction is a written notice from LADBS identifying items in your submitted drawings that need revision before the permit can issue. IBA prepares the correction response and resubmits revised plans — you don’t manage that process. For the full walkthrough of how correction cycles work and what drives multiple rounds, see the LADBS ADU Permit Process page.
