How Long Building Permits Really Take in Los Angeles
by Luxury Home Builders Inc. | 6 Min Read
The most common question we hear at the start of a custom home project is how long it takes to build. The more useful question is how long it takes to get approved. On most ground-up homes in Los Angeles, the approval phase takes longer than the framing, and it is the part owners are least prepared for. Here is what actually happens between buying a lot and breaking ground, and what drives the timeline in each step.
Quick Summary
- The biggest fork in your schedule is whether your project is by right or requires discretionary approval
- By-right projects skip public hearings and move substantially faster
- Plan check is not one review, it is several departments reviewing in parallel and in sequence
- Corrections are normal, and the number of correction cycles is the main variable within plan check
- Clearances from fire, sewer, grading, urban forestry and school districts each have their own queue
- Coastal zone, hillside and fire zone parcels add steps that cannot be shortcut
- Design quality early reduces approval time later, because clean drawings get fewer corrections
By Right Versus Discretionary
This single distinction matters more than any other to your schedule.
A by-right project complies with the zoning and the applicable ordinances as written. No one votes on it. It goes through plan check, collects its clearances and gets a permit. The timeline is driven by review queues and how clean your drawings are.
A discretionary project asks for something the code does not grant automatically. A variance, an adjustment, a zone change, a coastal permit, a haul route approval for large earthwork. These involve case filing, staff review, public notice to neighbors, a hearing and an appeal period. Each one adds months, and they do not always run in parallel.
Find out which category you are in before you buy the lot. A feasibility review answers it, and it is the cheapest useful money you will spend on the project.
Design and Engineering Come First
Nothing can be submitted until there is a complete set to submit. Schematic design, design development, then construction documents. Alongside that, structural engineering, civil engineering if there is grading, the geotechnical report, a survey and Title 24 energy compliance.
Owners often treat this phase as the part before the real project starts. It is the project. Decisions made here determine your cost, your approval path and your schedule. Rushing it reliably produces a slower permit, because incomplete drawings generate correction cycles.
If your site has geology questions, get the geotechnical investigation done before the design is finished. Redesigning a foundation after the drawings are complete is the most expensive sequence in custom building.
Plan Check Is Several Reviews, Not One
When the set is submitted to Building and Safety, it does not get read by one person. Structural, mechanical, electrical, plumbing, energy and accessibility review happen across different desks, and other agencies review in parallel.
Expect corrections. Corrections are not a sign something went wrong. They are the normal mechanism of the process, and every project gets them. What varies is how many rounds you go through, and that comes down to the quality and completeness of the submittal.
Each cycle has a rhythm: the plan checker issues comments, your team responds and resubmits, the set goes back in the queue. The queue is the part nobody controls. This is why experienced teams front-load effort into a complete first submittal rather than submitting early to start the clock.
Clearances Run on Their Own Schedules
A building permit is issued only after other departments sign off, and each maintains its own queue.
Depending on the parcel, you may need clearances covering grading, sewer capacity and connection, fire department access and water supply, urban forestry for protected trees, stormwater and low impact development, public works for any street dedication or improvement, and school district fees.
Some are quick. Some are not. The ones tied to a site condition, fire access on a narrow hillside street, a sewer connection that is not adjacent, a protected tree in the building footprint, tend to be the slow ones. They are also the ones you can identify early by walking the site with your builder and civil engineer.
What Adds Time to a Los Angeles Project
None of these are reasons not to build. They are reasons to know which ones apply before you commit, so the schedule you plan around is the real one.
- Coastal zone. Parcels in the coastal zone need a Coastal Development Permit, with its own review and appeal window
- Hillside. Slope affects allowable floor area, and larger earthwork can trigger a haul route approval with a public hearing
- Very High Fire Hazard Severity Zone. Additional fire department review covering access, water supply and rated assemblies
- Protected trees. Removal or encroachment requires its own approval
- Substandard street. May require a dedication, which brings public works into the schedule
- Historic or specific plan overlays. Additional design review in certain neighborhoods
How to Make the Process Faster
You cannot control the queue. You can control almost everything else.
Submit a complete, coordinated set the first time. Most delay inside plan check comes from correction cycles, and most correction cycles come from drawings that were not fully coordinated between architect, structural engineer and civil engineer.
Identify your clearances at the start and begin the slow ones early rather than discovering them at the end. Resolve geology before design is final. And decide the program early, because a change in scope after submittal sends you back through review.
Choose a team that has permitted in your specific jurisdiction. The cities we work in each have their own procedures and their own habits, and familiarity shows up directly in the schedule.
Plan Around the Real Timeline
We build custom homes from the ground up, and we have worked through approvals in Pacific Palisades, Malibu, Santa Monica, Brentwood, Venice and Mar Vista, as well as Sherman Oaks, Encino and Studio City.
If you want to know what the approval path looks like for a specific parcel, before you buy it or before you start design, we are glad to walk through it with you and tell you plainly which steps apply.
You can read how we run a build from lot to finish, see the areas where we build, or look at our work as a Santa Monica custom home builder.
Start with a Build Analysis. Before you commit to a schedule, we will review your parcel and tell you which approvals apply to it, by right or discretionary, and what that realistically means for timing. There is no charge for it. You can request one through our custom home building process.
Call 424-493-4051 or email info@luxuryhomebuildersinc.com. Our offices are at 984 Monument St #102 in Pacific Palisades and 15301 Ventura Blvd Bldg B in Sherman Oaks.
One note: procedures and fee schedules change. Confirm current requirements with the relevant department for your specific parcel rather than relying on what was true last year.
