What is LADBS Express Plan Check?

A paid expedited review service that moves your project to the front of the plan check queue for a 50 percent premium on plan check fees. The reviewers and review depth are identical, so plans still pass through Zoning, Building, Mechanical, Electrical, Plumbing, Fire, Green, and Energy. Express only compresses the time at each stage, cutting 30 to 50 percent off each cycle. You request it from the Intake clerk when you submit.

How much does Express Plan Check cost in Los Angeles?

The premium is 50 percent of the standard plan check fee, so it scales with project valuation. An 800 sqft detached ADU at $250,000 project value pays a standard fee of $2,500 to $3,500 and an Express premium of $1,250 to $1,750. A custom 1,200 sqft hillside ADU at $400,000 pays a standard fee of $4,000 to $5,500 and an Express premium of $2,000 to $2,750. A smaller $80,000 remodel pays a premium of $400 to $600.

How much time does Express Plan Check actually save?

About 4 to 8 weeks on a typical four-cycle ADU review. Standard plan check takes roughly 16 to 24 weeks of LADBS time across those cycles; Express takes roughly 10 to 16. It shaves 30 to 50 percent off each stage but does not reduce the number of correction cycles, so a project that needs five cycles still needs five.

When is Express Plan Check worth paying for?

Three scenarios. When you are paying construction loan interest, since loans typically accrue from day one and $300,000 at 8 to 10 percent costs $2,000 to $2,500 a month, so saving one or two months easily clears the premium. When you are paying $4,000 to $8,000 a month for temporary housing during a remodel. And when your contractor's bid has a 90-day validity window that your permit timeline would otherwise exceed, since LA construction costs rise about 4 to 6 percent a year.

When is Express Plan Check a waste of money?

When your bottleneck sits outside the LADBS plan check queue. Express does not speed up HPOZ or Office of Historic Resources review, Coastal Commission review, Planning Department design review for Specific Plans such as Mulholland or Venice, geotechnical or soils report turnaround, or materials lab testing. It is also wasted on pre-approved standard plans and SolarAPP+ projects that already issue same day, and on projects with known design problems where investing in a better first submittal beats paying to run flawed cycles faster.

LADBS Express Plan Check: when paying 50% more actually saves you money

LADBS lets you pay a 50% premium on plan check fees to jump the queue. The math, the trade-offs, and when this option pays for itself.

ByPermitPathLA· Sourced from LADBS fee schedule + plan check policy documentation

Most homeowners don't know LADBS offers a paid expedited review service. The Express Plan Check option moves your project to the front of the queue for an extra 50% on plan check fees. For some projects, that's a clear win. For others, it's wasted money. Here's how to tell.

What Express Plan Check actually is

LADBS plan check has a regular queue and an express queue. Express projects go to the front of the regular review pile and get faster turnaround at each stage. The reviewers and review depth are the same, your plans still go through Zoning, Building, Mechanical, Electrical, Plumbing, Fire, Green, and Energy. Express just compresses the time at each stage.

You request Express Plan Check at the same time you submit your application. The clerk at LADBS Intake will ask. The premium is calculated automatically and added to your fees.

The actual fees

Plan check fees in LA scale with project valuation. For a typical ADU project:

Detached ADU, 800 sqft, $250K project value: standard plan check fee around $2,500-3,500. Express premium adds $1,250-1,750. Total: $3,750-5,250.
Custom 1,200 sqft hillside ADU, $400K project value: standard fee $4,000-5,500. Express adds $2,000-2,750. Total: $6,000-8,250.
Smaller remodel, $80K project value: standard fee $800-1,200. Express adds $400-600. Total: $1,200-1,800.

So you're talking about $400 to $3,000 in extra fees depending on project size. The question is whether that buys you time worth more than the fee.

Time savings (real-world)

Express doesn't slash review times dramatically, it shaves 30-50% off each stage. For a typical 4-cycle ADU review:

Standard plan check: ~16-24 weeks of LADBS time across the cycles
Express plan check: ~10-16 weeks across the same cycles

Net savings: 4-8 weeks. Maybe a month, maybe two. Real but not transformative.

For projects that already qualify for the SolarAPP+ or pre-approved standard plan paths, Express adds nothing, those projects already issue same-day or near-same-day. Don't pay for Express on a YOU-ADU permit.

When Express makes financial sense

Three scenarios where the math works:

You're paying interest on a construction loan starting the day you close. Construction loans usually accrue interest from day one whether you've broken ground or not. At 8-10% APR on a $300K construction draw, you're paying $2,000-2,500/month in interest. A month of permit delay = $2K-2.5K. Express saves you 1-2 months. Easy win.

You're paying rent while waiting on your primary home addition. If you're moving out during a major remodel, you might be paying $4-8K/month for a temporary rental. Express saves a month of that.

Your contractor's bid expires. Many contractors quote prices with a 90-day validity window. If your permit timeline exceeds that, you may have to re-quote at higher prices (construction costs go up about 4-6% annually in LA). Express keeps you under the expiration window.

When Express doesn't make sense

You're not paying carry costs. If you live in the property already, aren't paying construction-loan interest, and your contractor's quote is locked, time-to-permit doesn't directly cost you money. Express buys speed you don't need.

Your project is already on the streamlined path. Standard plan ADUs, SolarAPP+ projects, and most simple residential work issues fast without Express.

Your project has complications Express can't solve. Express doesn't help with HPOZ design review, Coastal Development Permits, Mulholland Scenic SP review, or geotech report turnaround. Those bottlenecks aren't in the LADBS plan check queue, they're in separate review processes that Express doesn't touch. Paying Express on an HPOZ project doesn't help because the HPOZ approval still takes 2-4 months.

Your design has known issues that will require multiple correction cycles. Express speeds up each cycle but doesn't reduce the cycle count. If your project will take 5 cycles regardless, Express makes each cycle 30-50% faster but you're still doing 5 cycles. Sometimes better to invest in better-quality first submittal (hire a more experienced designer) than to pay for Express.

How to request Express Plan Check

Two paths:

At submittal: tell the Intake clerk you want Express. They add the premium fee to your invoice. You pay both the standard and Express portions before the application moves to review.

Mid-review (less common): you can request Express upgrade after submitting, but only certain stages allow this. Ask the assigned plan checker if upgrade is possible at your current stage.

Express doesn't apply to all permit types. Some specialty permits (LADBS Off-Hours, certain Engineering Bureau reviews) have their own expedite mechanisms or none at all.

Common mistakes

Assuming Express applies to all stages. Express speeds up LADBS plan check stages. It does NOT speed up:

HPOZ Board / Office of Historic Resources review
Coastal Commission review
Planning Department design review for Specific Plans (Mulholland, Venice, etc.)
Geotech report turnaround
Soils engineering report turnaround
Lab testing for materials

If your project's bottleneck is one of these, Express plan check is wasted money.

Paying Express on a YOU-ADU project. Pre-approved standard plans skip most of the plan check pipeline. They don't need Express. Don't pay the premium.

Confusing Express with "rush permit issuance." There's no LADBS "rush permit" service. Express speeds review; it doesn't skip review. If you need a permit issued in 2 weeks and your project requires standard review, Express alone won't make that happen.

What to do

For projects with significant carry costs (construction loan, temporary housing, expiring contractor quotes): yes, request Express at submittal. The math usually works.

For projects without carry costs: skip it. Use the savings to upgrade your designer or pay for a pre-submittal counter review.

For projects bottlenecked by overlay reviews (HPOZ, Coastal, Mulholland SP, etc.): skip Express. Pay for specialist help on the overlay-specific approvals instead.
