ADU Design & Permitting in West Hollywood - One Fixed Price, Permits Handled

Fast, Reliable ADU Design & Permitting Across West Hollywood

ADU design and permitting in West Hollywood runs through the city’s own Community Development Department, not LA City, and a complete garage conversion ADU - from site assessment through final inspection - typically costs $145,000-$210,000 all-in, with the permit set and construction under one written contract. We’re Ellery ADU Studio, a design-build practice founded in 2015, and our ADU Design & Permitting team handles the full stack: drawings, permit submittal, and construction coordination from our Los Angeles office.

Why Ellery ADU Studio Van Nuys Is West Hollywood’s Preferred ADU Design & Permitting Company

We’ve designed, permitted, and built more than 900 ADUs since 2015. Every one started with a written price before any work began, per Haven Standard Clause 1.

West Hollywood homeowners find us because we don’t treat their city as an extension of LA. WeHo is its own municipality with its own plan-check checklist, its own code interpretations, and its own timeline. Contractors who assume the LADBS fast-track rules apply here get sent back for revisions that add weeks. We submit to WeHo’s system the first time.

Our crews serve West Hollywood locally, dispatched from our Los Angeles office. Response time to a West Hollywood site assessment request is typically 24-48 hours.

Clients receive a documented photo record on every visit - evidence of what we found, not a summary of how it felt. And our 365-Day Done Right Promise is backed in writing before the project starts: if the finished ADU isn’t built to the permitted drawings, we make it right.

Our ADU Design & Permitting Services in West Hollywood

Site Assessment

Every West Hollywood ADU starts with a site assessment that accounts for what this specific housing stock hides. WeHo’s 1920s-1950s courtyard bungalows, Spanish Colonial Revival duplexes, and post-war stucco apartment buildings routinely contain knob-and-tube or early Romex wiring, undersized electrical panels, and framing that doesn’t meet current seismic or energy codes. We document everything with photos, flag the code triggers that will surface during permit review, and build allowances into the written contract so surprises are priced and approved before we touch anything. A typical site assessment in West Hollywood runs $1,800-$3,200.

ADU Design & Blueprints

Our permit set is the core product, not an afterthought. For a West Hollywood garage conversion, we produce architectural drawings, structural calculations, MEP plans, and Title 24 energy compliance documentation tailored to WeHo’s standalone plan-check checklist. We specify James Hardie siding and Tuff Shed modular systems where appropriate, and we coordinate Abodu prefab units within the same single contract. The design phase for a West Hollywood garage conversion typically runs $8,500-$14,000, with new detached ADUs at $12,000-$22,000 depending on complexity and slope.

Permit Application

West Hollywood’s Community Development Department processes ADU permits on its own timeline. We submit directly to WeHo’s plan-check team, not through LADBS, using their specific submittal format and checklist. Our field vignette: we pulled a garage-conversion permit for a 1920s Spanish Colonial Revival duplex near the intersection of Fountain and Fairfax, and once the drywall came off the back unit we found live knob-and-tube wiring feeding an undersized 100-amp panel - a guaranteed certificate-of-occupancy failure. Our tech priced a full 200-amp service upgrade and Title 24-compliant mini-split in writing, the owner approved before we touched anything, and we cleared WeHo’s plan-check on the revised drawings the second submittal. Permit filing and plan-check coordination in West Hollywood typically runs $4,500-$8,000.

HOA & Zoning Compliance

Many West Hollywood properties sit within homeowners associations or historic overlay districts that add a compliance layer beyond city code. We review CC&Rs, coordinate with HOA architectural committees, and ensure the ADU design satisfies both WeHo zoning and private covenant requirements before submittal. This prevents the mid-project stop-work order that derails timelines and budgets.

Title 24 Energy Compliance

California’s Title 24 energy standards apply to every new ADU and conversion. In West Hollywood, WeHo’s inland basin position produces hotter summer afternoons than coastal West LA, so detached garage conversions - which lack original insulation or HVAC - almost always require a dedicated mini-split system rather than passive ventilation alone to meet compliance and be livable. We model energy performance, specify equipment, and produce the compliance documentation WeHo requires for certificate of occupancy.

Common ADU Design & Permitting Problems We See in West Hollywood Homes

• Submitting LADBS-style drawings to WeHo’s standalone department. Contractors fluent in LA City’s process assume the same over-the-counter fast-track rules apply. They don’t. WeHo’s Community Development Department uses its own plan-check checklist, and submissions that skip WeHo-specific requirements get returned for revision, adding two to four weeks.
• Discovering knob-and-tube wiring or undersized panels mid-construction. West Hollywood’s pre-1950s housing stock routinely contains obsolete electrical systems that won’t pass certificate of occupancy. We find this during site assessment, price the upgrade in writing before work starts, and avoid the change-order scramble.
• Triggering rent stabilization ordinance violations on pre-1979 rental lots. West Hollywood’s RSO is among California’s most protective. An ADU added to a lot with existing pre-1979 rentals must be structured carefully to avoid relocation assistance and just-cause eviction requirements that simply don’t exist one block away in LA proper.
• Specifying passive ventilation for garage conversions. WeHo’s inland heat makes window or vent-only cooling insufficient for Title 24 and actual livability. We specify mini-split systems from the start, documented in the permit set, so plan-check clears and the space is usable.
