How Long Does a Building Permit Take in Los Angeles?

A Los Angeles building permit can take anywhere from same-day to several months, depending entirely on the permit type. A simple Express permit for a water heater or a like-for-like fixture swap can issue the same day. A standard remodel with a full plan check typically takes 2 to 8 weeks, averaging 3 to 4 weeks. A complex project involving structural work, an addition, or an ADU commonly takes 3 to 6 months once corrections and engineering review are factored in.

That range is wide because “a building permit” in Los Angeles is not one process, it is several different tracks depending on scope, and confusing them is the most common reason homeowners misjudge their own timeline before a project even begins. This guide breaks the timeline down stage by stage and by permit type, so you can budget a realistic schedule for your specific project instead of guessing from a single average.

Key Takeaways

• Express and over-the-counter permits for simple, non-structural work can issue the same day or within a few days.
• Standard plan check for a typical kitchen, bathroom, or non-structural remodel averages 3 to 4 weeks, with a realistic range of 2 to 8 weeks.
• Complex plan check for additions, ADUs, and structural work commonly runs 3 to 6 months, sometimes longer with multiple correction rounds.
• Corrections are the biggest variable. Each round of city corrections and resubmittal typically adds 2 to 4 weeks to the schedule.
• A complete, accurate submittal the first time is the single most effective way to shorten your timeline, more than anything else in your control.

The Three Permit Tracks in Los Angeles

LADBS routes every project into one of three tracks based on its complexity, and the track you land on determines your realistic timeline more than anything else.

Track	Typical timeline	Example projects
Express / over-the-counter	Same day to a few days	Water heater, like-for-like electrical or plumbing fixture, non-structural kitchen or bath remodel
Standard plan check	2 to 8 weeks (avg. 3 to 4)	Kitchen or bathroom remodel with plumbing or electrical changes, small non-structural additions
Complex / structural plan check	3 to 6 months, sometimes more	Room additions, second stories, ADUs, wall removals, custom homes

The gap between the fastest and slowest track is enormous, which is exactly why a single average number is not useful for planning. Knowing which track your project falls into is the first real step toward a realistic schedule.

The Permit Timeline Stage by Stage

For anything beyond an Express permit, the timeline breaks into distinct stages, and each one has its own typical duration.

1. Design and blueprinting

Before anything is submitted to the city, architectural plans, and for structural work, engineering calculations, have to be drawn up. This stage typically takes 2 to 6 weeks depending on project complexity, and it happens entirely before the LADBS clock starts.

2. Submittal through ePlanLA

Plans are submitted electronically through the city’s ePlanLA system. Submittal itself takes a day, but the completeness of what you submit determines everything that follows. An incomplete package does not fail quickly, it sits in queue and then gets flagged, costing more time than a complete submittal would have.

3. Plan check review

City plan checkers across structural, electrical, plumbing, mechanical, and fire-life-safety disciplines review the submittal. For standard projects, this review typically takes 2 to 4 weeks. For complex or structural projects, it can take 6 to 12 weeks or more, since more disciplines are involved and each one reviews independently.

4. Corrections and resubmittal

It is rare for a project to pass plan check with zero corrections. One to three rounds of corrections is typical, and each round adds real time, generally 2 to 4 weeks per cycle to address the comments, resubmit, and wait for the re-review. A project with three correction rounds can easily add two to three months to the overall timeline compared to one that passes clean.

5. Clearances from other agencies

Some projects need sign-off beyond LADBS itself, such as the Bureau of Sanitation for stormwater or grading-related items, or Fire Department review for certain scopes. Where these apply, they run in parallel with plan check but can still add 1 to 3 weeks if they surface late.

6. Permit issuance

Once plans are approved and fees are paid, the permit is issued, generally within a day or two of final approval.

7. Inspections through completion

This stage is not part of the “how long to get a permit” question, but it affects your total project timeline. Staged inspections, foundation, framing, rough plumbing and electrical, and final, happen as construction progresses, and work cannot proceed past certain points until each one passes.

What Actually Slows a Permit Down

Once you understand the stages, it becomes clear that a handful of factors explain almost all of the variation between a fast permit and a slow one.

• Incomplete submittals. Missing structural calculations, an unclear site plan, or absent Title 24 forms are the single most common reason a project loses weeks before review even meaningfully begins.
• Scope that crosses disciplines. A project touching structural, electrical, plumbing, and mechanical work all at once needs sign-off from every one of those reviewers, and the slowest discipline sets the pace for the whole permit.
• Zoning conflicts. A design that does not fit your lot’s setbacks or floor-area limit gets flagged and sent back for redesign, which is far more costly in time than catching the conflict before submittal.
• Special overlays. Hillside, coastal, Very High Fire Hazard Severity Zone, and Historic Preservation Overlay Zone properties add review layers and typically extend the timeline by several weeks.
• Seasonal backlog. LADBS review volume is not constant year-round, and submittals during the department’s busier periods can sit longer simply due to queue depth, independent of your project’s complexity.

How to Keep Your Permit Moving

Homeowners cannot control LADBS’s internal queue, but a few habits meaningfully shorten the realistic timeline.

The biggest lever is submitting a complete, accurate package the first time. Sealed structural calculations, a clear site plan with setbacks marked, and complete Title 24 documentation prevent the most common correction cycle before it starts. Second, respond to correction comments quickly and completely in one pass rather than addressing them piecemeal, since a partial response often triggers another round instead of closing the loop. Third, if your project touches a special overlay, hillside, coastal, fire zone, or historic district, confirm those requirements before design begins so the plans are built to satisfy them from the start rather than being redesigned mid-review. Finally, working with a design-build team that has been through the LADBS process repeatedly matters, because experienced teams know what a given plan checker typically flags and build the submittal to avoid it. That does not change how fast the city works, but it removes the self-inflicted delays that add up to the biggest gap between a fast permit and a slow one. We cover the fuller permit picture, including which projects need a permit at all, in our guide to Los Angeles remodeling permits.

What a Complete Submittal Actually Includes

Since an incomplete package is the single biggest source of delay, it is worth knowing exactly what “complete” means before you submit. For a standard or complex plan-check project, a complete package generally includes existing and proposed floor plans drawn to scale, a site plan showing property lines and setbacks, structural calculations sealed by a licensed engineer for any structural work, an electrical plan showing new circuits and any panel changes, a Title 24 energy compliance report for lighting, windows, or HVAC changes, and, where applicable, a soils or geotechnical report for hillside or foundation work. Missing any one of these does not necessarily stop the submittal from being accepted, but it almost guarantees a correction round once a reviewer reaches that discipline, which is functionally the same delay as never having submitted it.

A practical way to think about it: every missing document is a guaranteed 2 to 4 week round trip later, so the time spent assembling a complete package up front is rarely wasted, even when it feels like it is slowing down the start of the project.

Which Projects Qualify for an Express Permit?

Express permits are the fastest track LADBS offers, and knowing whether your project qualifies can save weeks. Generally, Express eligibility covers work that does not change the structure, does not alter the building’s footprint, and does not require a full plan check review across multiple disciplines. Common examples include water heater replacement, like-for-like electrical panel or fixture swaps, non-structural kitchen or bathroom updates that keep plumbing and electrical in place, and minor mechanical equipment replacement.

The moment a project adds square footage, moves a load-bearing wall, or requires sign-off from more than one review discipline at a meaningfully complex level, it moves out of Express eligibility and into standard or complex plan check. Homeowners sometimes assume a project is Express-eligible because it feels small, when in reality moving a single wall or adding one new electrical circuit for a large appliance is enough to require full review. Confirming eligibility before you plan the scope, rather than after, avoids a scheduling surprise.

How to Estimate a Realistic Timeline for Your Project

Putting the pieces together, a reasonable way to estimate your own timeline is to start with the track your project falls into, add expected correction rounds, and then add any special-overlay time if it applies. A standard plan-check kitchen remodel with no special conditions might run 3 to 4 weeks of review plus one correction round at 2 to 4 weeks, landing around 5 to 8 weeks total. The same project on a hillside lot, or one that also needs Bureau of Sanitation clearance, could add another 2 to 4 weeks on top of that. This kind of stage-by-stage estimate is far more useful than reaching for a single average, because it shows you exactly which parts of your specific project are adding time, and which parts, like a complete first submittal, are within your control to speed up.

How to Track Your Permit’s Status

Once a project is submitted, LADBS’s online system allows you or your contractor to check plan-check status, including which discipline is currently reviewing the plans and whether corrections have been issued. Checking this regularly, rather than waiting for a notification, can shave real time off a project, since some correction cycles start their clock the moment comments are posted rather than when you happen to check for them. A contractor who monitors this actively and responds to corrections within a day or two, rather than letting them sit for a week, is one of the most underrated ways to keep a complex permit on the faster end of its range instead of the slower end. That single habit, treating corrections as urgent rather than routine paperwork, often makes a bigger difference to the final timeline than any other decision made after submittal.

Planning Your Project Timeline Around the Permit Stage

Once you have a realistic estimate for the permit stage itself, the most useful next step is working backward from a target move-in or completion date rather than forward from a start date, since permitting is the least predictable part of most renovation timelines. If a hard deadline matters, such as a life event or a lease expiring, building in extra buffer specifically around the plan-check and correction stages, rather than the construction stage, reflects where the real uncertainty actually sits. Construction, once a permit is in hand, tends to follow a fairly predictable schedule; permitting is the phase most likely to run longer than expected, which is exactly why understanding it stage by stage, rather than trusting a single average number, is worth the time before a project begins.

Timeline by Common Project Type

Putting the stages and tracks together, here is what a realistic total permit timeline looks like for common residential projects, from submittal to issuance, not including design time beforehand.

• Non-structural kitchen or bathroom remodel: often issued through Express or a light plan check within days to about 2 weeks.
• Kitchen or bathroom remodel with plumbing, electrical, or a wall removed: typically 3 to 6 weeks through standard plan check.
• Room addition or second story: typically 2 to 4 months, longer on a hillside lot or with multiple correction rounds.
• ADU (detached or garage conversion): typically 2 to 5 months depending on design complexity and site conditions.
• Whole-home renovation or custom home: typically 3 to 6 months or more, given the number of disciplines and the scope involved.

These are planning ranges, not guarantees, and every one of them assumes a reasonably complete submittal. A project that needs several correction rounds can extend well past the upper end of its range, which is exactly why the submittal quality matters as much as the project type itself. Two projects of identical scope can land at opposite ends of the same range purely based on how thoroughly the plans were prepared before they ever reached a plan checker’s desk.
