How long does it take to get a building permit in Los Angeles?

Nobody can give you one number, and here is why#

The honest answer to this question is a range with conditions attached, and any builder who gives you a single date has either done this exact project in this exact jurisdiction recently or is guessing.

Los Angeles is not one permitting environment. It is dozens. The City of Los Angeles, unincorporated County areas and each independent city inside the county run their own departments, their own queues and their own review standards. A project in Santa Monica, a project in Pasadena and a project in an unincorporated hillside area are three different processes with three different calendars.

Within any one of those jurisdictions, the timeline is driven by three things: which review track the scope qualifies for, how complete the first submittal is, and how many other agencies have to clear the project in parallel.

Two tracks, and the gap between them#

Over the counter. A plan checker reviews the drawings while you wait, or within a short administrative window, and the permit issues immediately. This track exists for scopes that are small and standard: like for like replacements, reroofs, water heaters, some electrical and mechanical work, minor interior work with no structural change. Eligibility is defined narrowly, and a project that looks small can fall out of the track over one structural detail.

Full plan check. The submittal enters a queue, gets assigned to reviewers in several disciplines, and comes back as a written correction list. The design team responds, resubmits, and waits again. This is the track for essentially every new house, addition, structural remodel and commercial tenant improvement.

The difference between these two tracks is not a difference in degree. It is a day versus a season. The first question worth asking about any project is which track it lands in, because that answer alone accounts for most of the variance in permit timelines.

Correction cycles are the real clock#

Once a project is in full plan check, the calendar is not one review. It is a loop, and the number of times you go around it is what sets the date.

Cycle	What happens	Where time goes
First review	Plans assigned to each discipline, corrections written	Queue position, then review time
Response	Design team revises drawings and writes responses	Consultant availability
Resubmittal	Corrected set re-enters the queue	Queue position again
Second review	Reviewers check responses, often find new items	Review time
Approval	Remaining holds cleared, fees paid, permit issues	Other departments

Two or three cycles is normal on a custom residence. One is rare enough that it should make you suspicious of how thin the review was. Five or six usually means the first submittal was incomplete, and each additional loop costs both review time and queue time, which is why the total can double from one project to the next with no change in complexity.

The practical implication is that the biggest lever available to an owner sits before submittal, not after. A complete, coordinated, internally consistent set does not skip the queue, but it dramatically reduces how many times you have to stand in it. For more on what reviewers are checking and how correction lists work, the permitting topic covers that process in detail.

What pushes a project into discretionary review#

Ministerial review asks a single question: does this comply with the code. If the answer is yes, the permit is issued. Discretionary review asks whether the project should be approved at all, and that question gets answered by planners, commissions or hearing bodies rather than by a plan checker.

Common triggers include:

• A variance or any request to deviate from zoning standards
• Coastal jurisdiction, where a separate development permit process applies
• Hillside and grading thresholds, especially with significant earth movement
• Historic designation, or work adjacent to a designated resource
• Environmental review requirements on sensitive sites
• Neighborhood or specific plan overlays with their own design standards
• Projects that attract appeals, which restart parts of the process

Discretionary review is measured in hearing dates and noticing periods, not in correction cycles. That is why it changes the answer to this question so much: a hearing calendar has a rhythm nobody can accelerate, and one continuance can move a project by a month or more.

The parallel approvals people forget to schedule#

Owners think of permitting as a single application. It is usually a set of them, and the building permit cannot issue until the others clear. These run alongside plan check, and any one of them can become the long pole.

Grading and drainage. Any meaningful earth movement, retaining or drainage change draws a separate review and often a separate permit, with its own engineering and its own correction cycles.

Sewer and wastewater. Capacity availability, connection permits and, on some properties, a septic evaluation. On hillside lots this can involve a private sewer extension, which is a project of its own.

Fire. Access dimensions, turnarounds, hydrant flow, sprinkler requirements and defensible space in fire severity zones. Fire department conditions have killed more site plans than any other single agency comment.

Planning and zoning. Setbacks, height, floor area limits, parking and overlay standards. Planning clearance frequently has to precede building plan check rather than run beside it.

Public works and right of way. Driveway approaches, curb and gutter, street trees, sidewalk work, encroachment permits for anything touching the public way.

Utilities. Power service, meter location, transformer requirements, gas and water service. Utility work runs on a corporate schedule that has no relationship to the building department's, and it is the one people consistently apply for too late.

None of those clearances belong to the architect or the builder by default, which is exactly how they end up unowned until someone notices the building permit is being held by a sewer sign-off nobody applied for. Running that full set of agency applications in parallel, and tracking the conditions attached to each one, is the kind of coordination that sits inside specialty services on a complicated site.

How to read a permit schedule without fooling yourself#

Ask which jurisdiction and which track. Those two facts determine more than everything else combined. If nobody has confirmed the review track, the schedule is decoration.

Ask how many correction cycles are assumed. A schedule built on one cycle is an optimistic schedule. Two or three is a realistic one.

Ask which parallel approvals apply and when each was filed. Grading, sewer, fire and utility applications should have their own dates on the schedule, not be buried inside a single permitting bar.

Ask what happens if the design changes after submittal. The answer is that the revised set re-enters the queue, and knowing that in advance tends to keep late changes from happening.

Ask who is tracking it week to week. Applications sit. Someone has to be calling, checking status and responding within days rather than weeks, because a correction list that waits two weeks for a response has just added two weeks to the project.

What to plan around#

For budgeting purposes, treat a straightforward permitted project in a cooperative jurisdiction as a few months and a complex one as most of a year. Then build the schedule so that permitting is not the only thing happening during that window: finalize selections, order long lead items, and complete the constructability review that would otherwise generate field questions later.

The permit is not a document you wait for passively. It is a process with a response time on your side of it, and the projects that clear fastest are the ones where the design team turns corrections around in days rather than weeks. Plan on two to eight months, plan on corrections, and name the person whose job it is to chase the file. Every week an application sits unanswered is a week added to the move-in date, and that week is the only part of the calendar entirely within your control.
