Permit Application in Los Angeles, CA
Permit application for an ADU in Los Angeles is the formal process of submitting architectural plans, site documentation, and supporting paperwork to the Los Angeles Department of Building and Safety (LADBS) so your project can be reviewed, approved, and legally built. In plain English: it’s the paperwork stage between “we know what we want to build” and “we’re allowed to start digging.” Most LA homeowners find this is where projects stall, because LADBS submittal requirements shift depending on whether you’re in a Hillside area, a Historic Preservation Overlay Zone (HPOZ), or a standard flat-lot residential zone.
Lodgewick ADU Los Angeles handles permit application as part of our full ADU Design & Permitting in Los Angeles service. We prepare drawings to LADBS standards, assemble the package, submit it, track every correction comment, and resubmit until you have a permit in hand. If you’re stuck mid-permit or just starting to think about a garage conversion or backyard ADU, call us at (213) 698-7116 and we’ll tell you exactly what your project needs. You can also start with our home page if you want the full picture of what Lodgewick does.
When You Need Permit Application
If any of these sound like your situation, you need permit application work, not just design work. Here’s what we see most often in Los Angeles:
- You’re building a new ADU or JADU – a detached backyard unit or a converted garage or interior space. Every new accessory dwelling unit in Los Angeles requires a building permit through LADBS, full stop. There’s no legal path around it.
- Your garage conversion was never permitted – and now you’re selling, refinancing, or a neighbor filed a complaint. We submit a legalization package that brings the structure up to code and gets it on the books.
- You tried to submit plans and got a correction letter – LADBS plan check sent back a list of issues and you don’t know what half the comments mean. We read correction letters daily and know which ones are quick fixes versus real design problems.
- You’re in an HPOZ or Hillside zone – neighborhoods like Angelino Heights, Highland Park, or parts of Mount Washington have additional review layers. Plans that glide through in Northridge can take months in an HPOZ if the submittal isn’t tailored to the district’s preservation guidelines.
- You bought a property with existing plans that were never submitted – maybe the previous owner paid for drawings and walked away. We’ll audit those drawings against current LADBS requirements and tell you honestly if they’re usable or need a full redraw.
- You need a scope that touches multiple departments – ADUs sometimes trigger review from LADBS, LADWP (for utilities), and the Fire Department (for access and egress). We coordinate those submittals so one department’s requirement doesn’t conflict with another’s.
Our Permit Application Process
Here’s how Lodgewick ADU Los Angeles takes a project from “we have an idea” to “we have a stamped permit.” Every step is spelled out in writing before we start, so you always know where things stand.
- Site review and feasibility check. We visit the property, measure the lot, confirm zoning constraints (setbacks, height limits, lot coverage), and check LADBS records for any open violations or past permits on the property. This tells us if your ADU is even allowable before you spend a dollar on drawings.
- Design and plan preparation. We produce architectural drawings that meet current LADBS standards, including site plans, floor plans, elevations, structural calcs, and Title 24 energy documentation. If you’re working with a prefab system from ADU Design & Permitting in Los Angeles partners like Abodu or Dvele, we integrate their manufacturer drawings into the permit set so the engineering lines up.
- Submittal package assembly. We compile every form LADBS requires: the permit application, plot plan sign-off, school district approval form, LADWP clearance if applicable, and any HPOZ or coastal-specific documentation. Missing one form is the most common reason first-time submittals get bounced back.
- Submission and plan check tracking. We file electronically through LADBS’s ePlan system and monitor the review queue daily. When the plan checker issues corrections, we respond line by line. You get a plain-English summary of what was requested and what we did about it.
- Revision and resubmission. Most projects go through one to three rounds of corrections. We handle every round until the plans are approved. Then we pull the permit, pay the fees, post the permit card, and hand you a buildable set.
- Construction handoff and inspections support. If we’re building the ADU, we manage the inspection schedule with LADBS. If you’re using your own contractor, we walk them through the permit conditions so they don’t fail inspections for something our drawings didn’t cover.
Permit Application Pricing in Los Angeles
In Los Angeles, professional permit application services typically run $4,000 to $9,000 on top of city fees, with complex projects in Hillside or HPOZ zones landing closer to $12,000. City filing and permit fees are separate and usually range from $3,500 to $15,000+ depending on project valuation, square footage, and any school district or utility fees LADBS collects at issuance.
What moves the number:
- Project complexity. A simple one-story JADU conversion from a garage is on the low end. A two-story detached ADU with a foundation on a sloped lot is on the high end.
- Site conditions. Hillside lots trigger geology reports, retaining wall calcs, and sometimes Fire Department access review. That adds scope before we even submit.
- Drawing condition. If you come to us with usable plans, we’re auditing and submitting, less design time. If plans need a full redraw, that’s more hours.
- Correction rounds. We quote the submittal work up front, and we tell you what’s included. If LADBS comes back with something genuinely new, we show you the comment before we do anything extra.
| Service Component | Typical Range in Los Angeles |
|---|---|
| Site review and feasibility check | $450 – $900 |
| Full permit drawing package (ADU/JADU) | $3,000 – $7,500 |
| Submittal prep and LADBS filing | $800 – $1,500 |
| Plan check correction responses (per round) | $300 – $900 |
| City permit and filing fees (paid to LADBS) | $3,500 – $15,000+ |
We give a written price before any work starts. That’s The Kingswell Way and it’s non-negotiable for us. No one from Lodgewick ADU Los Angeles will change the number at the door, and if something in the scope changes, you’ll see the revised number in writing before we proceed.

What Makes Lodgewick’s Permit Application Different
Lodgewick ADU Builders has handled ADU permitting in Los Angeles since 2010. Led by Russ Delmar, our Los Angeles team has seen LADBS requirements change year over year, and we’ve adjusted our submittal process with each revision. That matters because a permit package that passed in 2021 may not pass today without updated energy calcs, updated structural standards, or updated accessibility notes.
Three things set our permit application work apart:
- The 365-Day Done Right Promise. If anything we permitted comes back wrong, whether it’s a miss on the drawings or a permit condition we didn’t explain, we come back and make it right. That promise is in writing on every project before work begins.
- Written price, always. Every permit application job gets a line-item written quote before we start. You know exactly what the submittal, tracking, and revision work will cost. No surprises after the first plan check.
- A live person answers the phone, 24/7. When LADBS updates their system at 6 a.m. and your permit status changes, you can call and talk to a person. Not a voicemail tree.
We also match your permit drawings to materials that work on your lot. For detached units, we’re familiar with panelized and prefab systems from Abodu, Cover, Dvele, and other manufacturers whose engineering needs to coordinate with LADBS submittals. For traditional builds, we specify materials like James Hardie siding when the design calls for it. The point is that drawings, materials, and permit conditions all line up before you’re standing at the counter wondering why the plan checker flagged your cladding detail.
Permit Application for Garage Conversions in LA
Garage conversions are the most common ADU type we permit in Los Angeles. The building already exists, which sounds easier, but the permit application has its own wrinkles. LADBS wants to see existing conditions documented carefully: wall framing, foundation condition, electrical capacity, and whether the garage slab meets current requirements for a living space. A common misconception is that you can convert a garage without touching the slab or addressing drainage. You can’t, and LADBS will catch it in plan check.
In neighborhoods like Mar Vista, Westchester, and the Valley communities of Reseda and Winnetka, we see the same pattern: older detached garages with minimal footings and single-circuit electrical panels. The permit package has to include an electrical load calculation and, in many cases, a foundation upgrade detail. We prepare all of that ahead of submission so your plan check doesn’t stall on a missing electrical schedule or an undersized beam.
Permit Application for Hillside ADUs
Hillside ADUs are a different animal altogether. Properties in areas like Echo Park, Silver Lake, Mount Washington, and parts of Sherman Oaks with significant slope trigger geology and soils reports, shoring plans for excavation, and in some cases, Fire Department review for access and turnaround. LADBS will not issue a hillside ADU permit without the geotechnical report, and that report has to be done by a licensed geotechnical engineer, not the designer.
Our team coordinates the geotech report, the structural engineering, and the LADBS submittal so all three speak the same language. We also flag Hillside Ordinance requirements early, because some lots have restrictions that make a detached ADU infeasible while a JADU is still fine. Knowing that before you spend $15,000 on design is the whole point of our feasibility check.
FAQs – Permit Application
How long does ADU permit approval take in Los Angeles?
In Los Angeles, a standard detached ADU permit application takes 4 to 6 months from submittal to issued permit, assuming plans are complete and corrections are minor. HPOZ reviews, Hillside reviews, and coastal-adjacent projects can add 3 to 6 months. We track every phase so you’re never guessing where your permit sits. Call (213) 698-7116 and we’ll give you a realistic timeline for your specific zone.
How much does an ADU permit application cost in Los Angeles?
Professional permit application services in Los Angeles usually run $4,000 to $9,000, with complex hillside or HPOZ projects reaching $12,000. City fees are separate and typically range from $3,500 to $15,000 or more based on project valuation. We provide a written line-item quote before any work begins. Call (213) 698-7116 for a free estimate.
Can I file my own ADU permit application in Los Angeles?
Yes, homeowners can file their own ADU permit application with LADBS, but most find correction rounds difficult to navigate without an architect or permit expediter. We’ve taken over dozens of homeowner-filed applications that were stuck in correction loops. If you’ve already filed and hit a wall, call (213) 698-7116 and we’ll tell you what it takes to get unstuck.
What happens if my ADU was built without permits?
If your ADU or garage conversion was built without permits, you can legalize it through LADBS by submitting a “legalization” permit application that documents the existing structure, upgrades any substandard work, and brings the unit to current code. The process takes longer and costs more than a new-build permit, but it protects your property value and keeps you clear of code enforcement. Call (213) 698-7116 for an honest assessment.
Does Lodgewick help with HPOZ permit applications?
Yes, we prepare and file HPOZ permit applications for ADUs in Historic Preservation Overlay Zones across Los Angeles. HPOZ review adds a layer of design scrutiny above standard LADBS plan check, and submittals must address the district’s preservation plan specifically. Our team has handled HPOZ submittals in districts including Angelino Heights, Carthay Circle, and Hancock Park. Call (213) 698-7116 to see if your property is in an HPOZ.
