ADU Design & Permitting Near You in Van Nuys, CA
If you’re searching for our ADU Design & Permitting services near you in the San Fernando Valley, Ellery ADU Studio works across Van Nuys and the surrounding neighborhoods under a single written contract – drawings, permit set, and construction at one upfront price, confirmed in writing before any work starts. We’ve designed, permitted, and built 900+ ADUs since 2015, every one of them documented with a photo record and backed by our 365-Day Done Right Promise. Call (424) 523-8492 – a live person picks up, no voicemail.
Nadia Ellery founded this studio the same year California’s ADU permitting rules shifted meaningfully – 2015 – because she saw how often homeowners got caught between a designer who handed off drawings and a builder who claimed the drawings were wrong. The one-contract model exists to close that gap permanently. Under Haven Standard Clause 1, you receive a written price before anything moves forward. That number covers ADU Design & Permitting in Van Nuys, site assessment, permit filing, and construction through final inspection.
The customers we work with most often bought in Van Nuys, Sherman Oaks, or Encino between 2015 and 2024, paid a serious price for their lot, and are now thinking carefully about whether an ADU makes sense as a long-term asset. They’ve read enough to know that the permit set is where most projects fall apart. We agree. It’s the core product here, not an afterthought.
Fast, Local ADU Design & Permitting in Van Nuys
Van Nuys sits in the geographic center of the San Fernando Valley, which means our crews reach most client sites in 20 to 35 minutes. Initial Site Assessment visits can typically be scheduled within two business days of your first call. From assessment to a completed permit submittal to the City of Los Angeles Department of Building and Safety, most projects run six to ten weeks on the design side – longer when a lot has unusual setback conditions or requires a lot line adjustment, shorter when the lot is clean and the conversion is a straightforward garage-to-ADU.
Los Angeles’s Standard Plan Program has accelerated approvals on some unit types, and Ellery’s Permit Application team tracks which plan types qualify. If your project is eligible, we flag it early and price the expedited path into the written quote – no surprise upgrade fees later.
Areas We Cover Near Van Nuys
Our primary service territory runs across the central and western San Fernando Valley, with active projects currently in Van Nuys, Sherman Oaks, Encino, North Hollywood, Studio City, Northridge, Tarzana, and Burbank. Each of those cities sits within the City of Los Angeles jurisdiction or an adjacent incorporated city with its own building department, and the permit requirements differ in meaningful ways.
In North Hollywood and Studio City, R1 lots often have HOA & Zoning Compliance issues like rear-yard setback conditions that surprise homeowners who assumed their garage conversion was straightforward – the 4-foot side and rear setback rule under California’s ADU law applies statewide, but local fire-access requirements in denser North Hollywood blocks sometimes add a layer. In Encino and Sherman Oaks, we regularly encounter lots with steep slope conditions that push site prep costs up before a single drawing is filed. We name those numbers in your written quote, not after the foundation is poured.
Burbank operates under its own building and safety department, separate from the City of Los Angeles, and its ADU ordinance has specific owner-occupancy history requirements that were updated in 2023. If your property is in Burbank, we confirm current requirements at the time of your assessment – not from a guide written two years ago.

Before
AfterWhat Ellery Quotes Cover – and What That Means in Practice
A written quote from Ellery covers five categories under one contract: ADU Design & Permitting, Garage Conversion ADU, New Detached ADU, Junior ADU and Interior Conversion, and Site Prep & Utilities. Below is a range table based on current Van Nuys-area market conditions. These are all-in figures – drawings through final inspection – not base prices with a long list of exclusions.
| Project Type | Typical All-In Range (Van Nuys Market, 2025-2026) |
|---|---|
| Garage Conversion ADU (existing slab, standard condition) | $130,000 – $185,000 |
| Junior ADU / Interior Conversion | $80,000 – $130,000 |
| New Detached ADU (up to 850 sq ft, site prep included) | $220,000 – $340,000 |
| Prefab / Modular ADU (Abodu, Cover, Plant Prefab, etc., coordinated by Ellery) | $180,000 – $290,000 all-in, including site and permit |
| ADU Design & Permitting Only (drawings + permit filing) | $18,000 – $32,000 depending on unit type and lot complexity |
Every figure in that table assumes a written scope confirmed before work starts – Haven Standard Clause 1. If the site assessment reveals a condition that changes the number (a slab that’s thinner than the standard 4 inches, a utility lateral that needs relocation, a setback that requires a variance), that change is documented and presented to you in writing before we proceed. Under Haven Clause 5 (No Surprises), the scope is locked at signing.
Prefab and Modular ADU Options Near Van Nuys
Several of our Van Nuys and Northridge clients have asked specifically about prefab and modular systems. Ellery specifies and coordinates units from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie within the same single contract – you don’t manage a separate relationship with the manufacturer while also managing a general contractor. The permit set is drawn to the specific module, the site prep is scoped to the delivery requirements, and the final inspection is included.
One thing worth knowing: not every prefab system qualifies for the City of Los Angeles’s pre-approved plan program, and factory lead times vary considerably – Abodu and Cover currently run 12 to 20 weeks from order to delivery; Boxabl’s timelines have been less predictable. We price the realistic schedule into the written quote, not the manufacturer’s optimistic estimate.
The Van Nuys Permit Process, Step by Step
Van Nuys addresses file with the City of Los Angeles Department of Building and Safety, which processes ADU applications through its Permit and Construction Services Centers. The broad sequence runs like this:
- Site assessment and zoning confirmation: We verify your lot’s zoning designation, setback requirements, utility connections, and any recorded easements. This is where slope conditions and existing-structure quality are documented with the photo record you receive.
- Schematic design and written quote: Based on the site data, Nadia Ellery’s team produces a schematic and a written all-in price under Haven Clause 1. You sign before we draw anything further.
- Construction documents and permit set: Full architectural drawings, structural calculations (required for new detached ADUs and most garage conversions), Title 24 energy compliance, and mechanical/electrical/plumbing plans are prepared to LADBS submission standards.
- Permit submittal and plan check: We file electronically through the LADBS portal. Standard plan check runs four to eight weeks; over-the-counter approval is available for qualifying projects under the Standard Plan Program.
- Construction: Our crews build to the permitted drawings. If anything deviates from the approved set, the 365-Day Done Right Promise requires us to correct it – in writing, before the project starts.
- Final inspection and certificate of occupancy: LADBS conducts a final inspection. We coordinate the inspection date, attend, and provide you with the certificate and the completed photo record.
Van Nuys lots built out between the 1940s and 1960s – and there are thousands of them between Victory Boulevard and Vanowen Street – often have older utility infrastructure that needs documentation before a permit is filed. We flag this at step one, not step four.
The 365-Day Done Right Promise – What It Actually Means
Most contractors offer a warranty that exists in conversation. Ellery’s 365-Day Done Right Promise is written into the contract before work starts. If the finished ADU is not built to the permitted drawings – a wall in the wrong location, a ceiling height that doesn’t match the approved set, a utility rough-in that fails inspection – we return and make it right at no additional cost. The promise covers the twelve months following the date of final inspection.
This matters in Van Nuys specifically because the City of Los Angeles conducts multiple inspections during construction (framing, rough MEP, insulation, drywall, final), and deviations that pass one inspection can surface at the next. Having a written remedy in the contract means you’re not negotiating after the fact.
Free Second Opinion on Any Written Estimate
If you’ve already received a written estimate from another studio or contractor and you want a second set of eyes on what it covers – and what it leaves out – Ellery offers a free second opinion. Nadia Ellery or a senior member of the design team reviews the scope, the exclusions, and the permit plan (if one exists), and gives you a plain-language summary of what you’d be committing to. No pressure, no obligation. Call (424) 523-8492 to set it up.
Frequently Asked Questions
How fast can Ellery start on my ADU project near Van Nuys?
Initial site assessments are typically available within two business days of your first call in the Van Nuys area. The full design-through-permit timeline runs six to ten weeks from signed contract to permit submittal, depending on lot complexity. Garage conversions on clean lots with existing slabs move faster; new detached ADUs on sloped Encino or Tarzana lots take longer because the structural and grading documentation is more involved. Call (424) 523-8492 and a live person will confirm current availability the same day.
Do you serve my neighborhood – I’m not sure if I’m in Van Nuys or a neighboring city?
Ellery ADU Studio actively covers Van Nuys, Sherman Oaks, Encino, North Hollywood, Studio City, Northridge, Tarzana, and Burbank. The boundary between Van Nuys and North Hollywood, for example, runs along the 170 Freeway corridor, and several streets that feel like Van Nuys file permits under a North Hollywood district office designation. Call or text (424) 523-8492 with your address and we’ll confirm your jurisdiction and department in minutes.
What does ADU design and permitting cost near Van Nuys in 2025-2026?
Design and permitting only – architectural drawings, structural calculations where required, Title 24 compliance, and permit filing through LADBS – runs $18,000 to $32,000 for most Van Nuys-area projects, depending on unit type and lot conditions. All-in design-build pricing (drawings through final inspection) ranges from roughly $80,000 for a junior ADU interior conversion to $340,000 for a new detached unit on a lot with significant site prep requirements. Every figure is confirmed in a written quote under Haven Standard Clause 1 before any work begins – the price you see in writing is the price you pay unless you change the scope.
Can I reach someone after hours if I have a question about my ADU project?
Yes. A live person answers calls to (424) 523-8492 around the clock – no voicemail queue, no next-business-day callback. ADU projects don’t generate emergencies the way a burst pipe does, but permit deadlines, plan-check response windows, and inspection scheduling sometimes require a same-day answer. If you call at 9 PM with a question about a plan-check comment you received that afternoon, someone picks up.

What Our Customers Say
"The rental income has covered the payment since the second month. They were realistic about the numbers rather than optimistic."
- Odette N."They walked us through setbacks and utility capacity before we paid anything, and told us one of our two options was not going to get approved."
- Mireille T."The permit set and the build were one contract with one number. Our neighbours used two firms and spent a year watching them blame each other."
- Helena V.
