What plan check actually checks, and why it takes more than one round

By Ram Gabay, DVLP Construction  ·  7 minute read

Plan check is the City reading every sheet of your drawings against the building code, the zoning code and the energy code, and collecting sign-offs from the other departments that touch your lot. On a standard custom home in the City of Los Angeles, expect two to three rounds of corrections, and three to five weeks for each round. Nobody gets approved on the first pass. The goal is to make the second round the last one.

What goes in the box

A new single-family home in the City goes through what the Department of Building and Safety (LADBS) calls Regular Plan Check, the track for large and complex projects. The set can be uploaded online through the City’s ePlanLA system. Either way, it is the whole house on paper:

• The topographic survey your architect designed on
• Architectural plans: site plan, floor plans, elevations, sections, roof plan
• Structural drawings and calculations: foundation plan, framing plans, details
• Grading and drainage plans from the civil engineer
• The soils report, with the City’s approval letter
• Title 24 energy documents and green building notes

Each consultant stamps and signs his own sheets. That matters later, because when a correction comes back, it goes to the person whose stamp is on that sheet.

What the plan checker actually checks

People picture one inspector with a red pen. In practice your plans are read against several separate rulebooks, and some of them are not even at Building and Safety.

The clearances catch owners off guard. They run on each department’s own schedule. A house set far back from the street can need Fire Department sign-off on access. A new home on a lot without a sewer close by needs Public Works to confirm how it connects. None of that is about whether the house is well designed. It is about the City making sure the lot can serve it.

Why it never passes on the first round

The first review comes back as a correction list, sorted by discipline. Some items are clerical: a missing detail, a note that has to be added, a reference to the wrong code section. Some are real engineering questions. Almost all of them have to be answered by someone other than you.

Here is why one round turns into two or three:

• One change moves other sheets. If the plan checker makes the architect move a wall to meet a setback, the structural engineer may have to rework that wall’s calculations, and the energy numbers can change with it. Every consultant has to catch up before the set goes back.
• The resubmittal gets read, not just ticked off. The plan checker reviews the revised sheets, and a fix in one place can raise a new question in another.
• Clearances move on their own clock. The building review can be finished while a department sign-off is still open.
• Late inputs. If the soils report was not approved before the plans went in, the foundation design is waiting on it, and that correction cannot be closed.

How long it really takes

Palisades rebuilds in the City move faster because the Mayor’s emergency orders put them on an expedited track. Most still see more than one round. If you are rebuilding after the fire, which order you file under changes what the plan checker is reading your plans against.

What keeps it to two rounds

You cannot skip plan check, and you cannot make the City read faster. What you can control is how clean the set is when it goes in, and how fast it comes back.

1. Get the soils report approved first. The approval letter has to be part of the plans, and the foundation design depends on it. A report ordered late is the most common way a project stalls before it ever reaches plan check. Here is why it takes as long as it does.
2. Settle zoning early. On a hillside lot the maximum floor area is not a guess. Get the slope analysis approved before the design is finished, not after the plan checker asks for it.
3. Coordinate the consultants before the set goes in. When the architect, structural engineer, civil engineer and energy consultant are all drawing the same house, the first correction list is shorter.
4. Answer every item, completely. A correction answered halfway comes back in the next round. We make sure each consultant closes his items, and we track what is still open.
5. Freeze the design. Changing the house during plan check means sheets that were already reviewed get reviewed again. Make the design decisions before the set goes in.

One date worth knowing: when the City accepts a complete plan check submittal and the plan check fee is paid, the project generally locks in the zoning rules in effect on that day. That protection runs out 18 months after the fee is paid, or when the building permit expires, and a big change to height or floor area can void it.

What happens after approval

Once the plans and every clearance are approved, the project is “ready to issue.” You pay the permit fees, the plan checker stamps the approved set, and the building permit is issued. Only then can construction start. The approved set is the one the inspectors will hold the job to, sheet by sheet, for the rest of the build.

Requirements vary by lot and change over time. This reflects the City of Los Angeles Department of Building and Safety plan check process and published correction sheets as of fall 2026.
