We coordinate dispatch and scheduling from our Los Angeles office, and our crews serve West Los Angeles neighborhoods including Mar Vista, Palms, and Sawtelle daily. Nadia Ellery has led Ellery ADU Studio since 2015, the year California’s ADU laws shifted, and our team has designed, permitted, and built more than 900 ADUs - every one with a documented photo record and a written price locked at signing.

Why Ellery ADU Studio Westchester Is West Los Angeles’s Preferred ADU Design & Permitting Company

West Los Angeles homeowners know the difference between a contractor who pulls permits and a design-build studio that treats the permit set as the core product. Our ADU Design & Permitting team has handled so many Mar Vista garage conversions that we can spot a 100-amp panel or galvanized supply line from the driveway - the exact conditions that derail first-time ADU builders at rough-in.

Clients in West Los Angeles receive the same documentation we provide everywhere: a written scope, a permit set stamped by our architect, a photo record from every site visit, and the 365-Day Done Right Promise in writing before ground breaks. Our license number appears on every page, and our crews are background-checked and uniformed.

A live person answers our phones 24/7. No voicemail queue, no callback that doesn’t materialize. If you already have a written estimate in hand, we’ll give you a Free Second Opinion - no obligation, no pressure.

We don’t do urgency theatre. We do named prices, named clauses, and named deliverables.

Our ADU Design & Permitting Services in West Los Angeles

Site Assessment

Every West Los Angeles project begins with a site assessment that documents what is actually there, not what a Zillow photo suggests. On a typical 5,000-7,500 sq ft lot in Palms or Sawtelle, we’re checking four things: the garage slab thickness and condition, the electrical service amperage and panel location, the water supply line material and pressure, and the setback distances to property lines and any protected trees. These 1940s-1960s stucco bungalows and ranch homes often carry original infrastructure that must be upgraded before an ADU can receive final sign-off. We photograph everything and deliver a written findings report with line-item recommendations - no summary of how it felt, just what we found and what it means for your scope.

ADU Design & Blueprints

Our design team produces permit-ready drawings that account for West Los Angeles’s specific conditions. For garage conversions, we often specify vapor-open wall assemblies and mechanical ventilation strategies that inland contractors overlook - the coastal fog belt here runs 10-15°F cooler and measurably more humid than Burbank or Pasadena, and trapped moisture behind poorly specified siding has failed Title 24 verification for more than one WLA homeowner. We also coordinate prefab and modular systems from brands including Mighty Buildings, Plant Prefab, and Boxabl within the same single contract, so neither the designer nor the builder can point at the other when something is off.

Permit Application

Here’s where local knowledge pays. Because West Los Angeles sits inside City of Los Angeles jurisdiction, our permit expediters can pull from the Bureau of Engineering’s Standard Plan Program - pre-approved ADU blueprints that compress plan-check from months to weeks on straightforward garage conversions. This workflow shortcut is essentially unknown to homeowners but separates fast-moving WLA ADU contractors from slow ones. Mar Vista has become one of the most ADU-dense neighborhoods in Los Angeles precisely because experienced expediters know how to route projects through this program. For custom designs or complex sites, we manage the full plan-check process, responding to corrections until the permit is ready to issue.

HOA & Zoning Compliance

Newer master-planned developments in West Los Angeles - particularly pockets built in the 1990s and 2000s - often carry HOA architectural rules that override the City of LA’s permissive ADU ordinance. We’ve seen homeowners spend $8,000-$12,000 on custom drawings only to learn their HOA requires a specific roof pitch, exterior finish, or setback that forces a complete redesign. Our HOA & Zoning Compliance review checks these overlays before a single line is drawn. We contact the management company, pull the CC&Rs, and flag any restrictions that would affect your ADU design. Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing; no door-side upsells, no scope creep.

Title 24 Energy Compliance

California’s Title 24 energy code applies in full across West Los Angeles, including mandatory heat pump provisions for new ADUs. The mild coastal climate does reduce mechanical HVAC loads, but it does not exempt you from the code. Our permit sets include the CF-1R forms, equipment specifications, and insulation details that the city requires. We also specify moisture-resistant assemblies that satisfy both Title 24 and the fog-belt humidity reality - a combination that contractors unfamiliar with coastal conditions often miss.

Trusted Brands We Service in West Los Angeles

Ellery ADU Studio specifies and coordinates prefab and modular systems from Mighty Buildings, Plant Prefab, Boxabl, Tuff Shed, and James Hardie within our single-contract design-build model. For West Los Angeles clients, this means we can compare a site-built garage conversion against a Plant Prefab unit or a Mighty Buildings panelized system using the same written scope and the same permit expediter - no competing quotes from designers who don’t build and builders who don’t design. We maintain relationships with local suppliers and fabricators to keep lead times predictable, and we document every delivery with the same photo record we provide on every site visit.

Common ADU Design & Permitting Problems We See in West Los Angeles Homes

• Assuming the existing 100-amp panel can handle an ADU load. Most 1940s-1960s stucco bungalows in Mar Vista and Palms carry original 100-amp service. Inspectors flag this at rough-in every time. We upgrade to 200-amp during design, not during construction, so the permit set matches the final build.
• Hiring an inland contractor who ignores coastal vapor management. The fog belt’s humidity will trap moisture behind vinyl siding or inside unventilated garage-conversion walls. We specify vapor-open assemblies and mechanical ventilation that satisfy both Title 24 and the local climate reality.
• Skipping HOA review before drawing plans. Newer master-planned developments in West Los Angeles can enforce stricter rules than the city itself. We’ve seen HOA architectural committees reject ADU designs that already carried city approval. Our HOA & Zoning Compliance review prevents this.
• Missing the Standard Plan Program window. Homeowners who don’t know about the City of LA’s pre-approved blueprints wait months for custom plan-check. Our permit expediters route straightforward garage conversions through this program routinely, cutting timeline and cost.
