Electronic plan submission for a permit sounds simple: upload drawings, pay fees, and wait for comments. In practice, most delays happen before review even starts. Files are rejected because sheets are missing, scans are unreadable, dimensions do not match, or the package does not follow the city or county’s digital intake rules. If you are applying for California building permits, learning the basics of e-plan submission can save time and prevent frustrating restarts.
This guide explains how the electronic plan submission permit process usually works in California, what documents departments commonly ask for, and how existing-condition drawings fit into the permit process. Because every jurisdiction has its own portal, naming standards, and checklist, you should always confirm local requirements before uploading. If you are still getting oriented, our complete guide to California building permits gives useful background on the bigger process.
What electronic plan submission means
Electronic plan submission, often called e-plan check or e-plan review, is the digital version of turning in a paper permit set at a public counter. Instead of printed sheets, you submit PDF files through an online portal. The building department then routes those files to plan reviewers, who mark comments digitally and return a correction list or approval status through the same system or by email.
In California, electronic review is now common for residential remodels, additions, tenant improvements, ADUs, and many commercial projects. Some departments accept fully digital submittals from start to finish. Others still require a later in-person step, wet-signed forms, or hard copies after approval. The key point is that the permit process is now document-driven in a very literal way: if your files are not organized and legible, your application may not even reach the first review cycle.
- Application forms are completed online or uploaded as PDFs.
- Plan sheets are submitted as digital files, usually to scale and flattened.
- Review comments come back electronically.
- Revisions must be clouded, dated, and re-uploaded correctly.
- Approval may lead to digital permit issuance, printed job cards, or both.
Electronic submission does not change the technical standards of the drawings. It changes how clearly your information has to be packaged. That is why good existing-condition documentation matters so much at the front end.

Why complete existing drawings matter before you upload
Many permit applications stall because the proposed drawings do not accurately reflect what is already built. Reviewers compare your new work against the current condition of the site, structure, and floor plan. If dimensions are inconsistent, walls are mislabeled, window and door locations are unclear, or square footage calculations do not add up, the permit process slows down.
That is where field-measured as-built drawings help. FastAsBuilt provides field-measured as-built drawings and measured floor plans across California. Our local crews serve Southern California, the Bay Area, and San Diego. We use on-site laser measurement, then senior drafters produce permit-ready CAD files in PDF and DWG format. For many remodels and change-of-use projects, this creates a clean baseline before your designer, architect, or engineer prepares the proposed set.
If you are unsure whether your project needs existing plans, see whether you need existing plans to pull a permit. For remodel work especially, you may also want to review when as-built drawings are needed for a remodel permit. In electronic plan check, existing drawings are not just helpful background. They often determine whether reviewers can understand the scope at all.
How the typical California e-plan process works
While each city and county uses its own software, the sequence is usually similar. You create an application, upload the required files, receive an intake screening result, pay initial fees if required, and then wait for plan review comments. After that, you revise and resubmit until the project is approved or denied.
Step 1: Pre-submittal preparation
Before you log into a portal, gather the core information: project address, assessor parcel number if requested, owner and applicant contact information, scope of work, occupancy or use information where relevant, and your full drawing set. This is also the time to confirm whether your jurisdiction requires separate files for architectural, structural, energy, site, and supporting documents.
Step 2: Initial upload
You upload your application forms and plan files. Some systems require one combined plan set PDF; others require each sheet or discipline as its own file. Many jurisdictions also ask for supporting documents such as product cut sheets, structural calculations, Title 24 forms, photographs, and authorization letters.
Step 3: Intake screening
Before technical review starts, staff often do a completeness check. They are looking for missing sheets, incorrect orientation, blurry scans, absent signatures, or file names that do not match the checklist. A project can be rejected here without any code review at all.
Step 4: Plan review
Once accepted, the package is routed to building and often to planning, public works, fire, health, or other departments depending on the scope. To understand this stage better, see what plan check is and why existing drawings matter.
Step 5: Corrections and resubmittal
You respond to comments, revise the affected sheets, cloud changes, update dates or revision numbers, and resubmit exactly as the portal instructs. Inconsistent resubmittals are one of the most common causes of avoidable delay.
Step 6: Approval and permit issuance
After all departments sign off, fees are finalized and the permit is issued. Some jurisdictions issue approved digital sets with stamps or watermarks. Others require you to print an approved job copy for the site.

FastAsBuilt sends a local crew to laser-measure your property and delivers permit-ready 2D or 3D drawings, starting at $900.
See 2D & 3D pricingWhat files you usually need for an electronic plan submission permit
The required package depends on the project type, but most California jurisdictions ask for more than just floor plans. If you submit too little, reviewers cannot evaluate the work. If you submit disorganized extras, staff may have trouble locating the controlling information. A clean, complete package works best.
- Permit application form
- Architectural plan set
- Site plan, when applicable
- Existing and proposed floor plans
- Exterior elevations and building sections, when applicable
- Structural drawings and calculations, if required
- Title 24 energy documentation, when applicable
- Product approvals or manufacturer cut sheets
- School, fire, or utility forms where required
- Owner-builder verification or agent authorization forms if applicable
For a practical overview of the drawing package itself, read what drawings you need for a building permit in California. If your project includes energy compliance, it also helps to understand what Title 24 means in California. Title 24 requirements vary with the scope, so confirm the exact forms and calculations needed with your local jurisdiction and your energy consultant or design professional.
When existing conditions are missing or uncertain, permit reviewers may ask for field verification. FastAsBuilt can provide 2D As-Built Plans starting at $900 for up to 1,500 square feet, then $0.50 per square foot, with one revision and typical 48–72 hour delivery. We also provide 3D As-Built Plans starting at $1,500, then $1.00 per square foot, including a 3D model plus 2D floor plans, elevations, and sections, with two revisions and typical 3–5 business day delivery. Custom commercial, ADU, SB 9, and tenant improvement projects are quoted individually.
Turnaround times are estimates and may vary based on project complexity and scheduling.

File formatting rules that often cause rejections
Most e-plan problems are administrative, not design-related. A strong set can still be kicked back if the files do not meet portal standards. Local instructions vary, but these formatting issues come up again and again.
- File names are too vague, too long, or do not match the required naming pattern.
- Plan sheets are uploaded sideways or upside down.
- Scans are low resolution, washed out, or include dark backgrounds.
- Pages are missing, duplicated, or out of order.
- Large files are not flattened and become slow or unreadable in review software.
- Handwritten markups are hard to read.
- The set mixes existing and proposed information unclearly.
- Dimensions or notes are too small to read on screen.
- Supporting documents are embedded where the portal wants separate uploads.
A good rule is to think like an intake reviewer. Can someone unfamiliar with the project open your files quickly, identify every sheet, read every note, and understand the scope without guessing? If not, revise before submission.
It also helps to export from CAD directly to clean PDFs rather than relying on phone photos or old scans. FastAsBuilt’s measured plans are produced by senior drafters in permit-ready CAD, which helps create legible PDF and DWG files suitable for downstream design and permitting work.
How to organize your digital plan set so reviewers can follow it
Electronic review goes faster when the story of the project is easy to follow. That means your sheets should move in a logical order from general to specific. Reviewers should be able to understand the location, current condition, proposed work, and code-related notes without jumping between unrelated files.
Useful organization practices
- Start with a cover sheet if your project is large enough to justify one.
- Clearly label sheets as existing, demolition, and proposed.
- Keep floor plans, elevations, sections, and details coordinated.
- Use consistent room names, dimensions, and north orientation.
- Separate deferred submittals if the jurisdiction wants them later.
- Match drawing titles to file names where possible.
- Include a concise scope of work in both the application and plan set.
For remodels, one of the most common review issues is poor distinction between what stays and what changes. Existing-condition plans should not look identical to proposed plans unless that is truly the case. If reviewers cannot tell what is being removed, altered, or added, they will comment.
If you are building the permit set from scratch, our article on getting permit-ready as-built drawings can help you prepare the baseline correctly before the design package is finalized.
How to handle corrections, revisions, and resubmittals
Almost every permit project receives comments. The goal is not to avoid all corrections; it is to respond clearly and completely. In e-plan systems, partial or sloppy resubmittals can restart review or create confusion about which sheet controls.
When you receive correction comments, read all departments’ notes first. Then prepare a coordinated response. If one change affects several sheets, update every affected sheet before resubmitting. For example, if a wall type changes, that may affect the floor plan, section, structural notes, and energy documentation.
- Create a response letter or comment matrix if the jurisdiction allows or requires it.
- Reference each reviewer comment directly.
- Cloud every drawing change and update revision dates.
- Do not remove earlier approved information unless the comment requires it.
- Upload revised files into the correct resubmittal slots.
- Keep file names and sheet numbers consistent from cycle to cycle.
Some cities ask for one full revised set; others want only changed sheets plus a response letter. Always follow the portal instructions exactly. If you are unsure whether a revision is substantial enough to trigger wider updates, ask the plan checker or your design professional before submitting.

California-specific issues to watch during permit review
The permit process in California often involves more than building review alone. Planning overlays, wildfire considerations, energy compliance, coastal rules, historic review, and local zoning standards may all affect the submittal. Electronic plan submission does not reduce those requirements; it simply moves them into a digital workflow.
For residential work, common California review topics include setbacks, lot coverage, floor area, and energy compliance. If your project changes the building envelope or intensity of use, those zoning-related items may matter as much as the construction drawings. Local departments may also require ADU-specific forms, school fee coordination, or agency sign-off depending on the scope.
Some state laws can influence how projects are reviewed or what owners are trying to permit. For example, SB 9 can affect lot split and housing development pathways on qualifying properties, while ADU-related rules under state law can shape submittal requirements for accessory dwellings. Balcony and exterior elevated element inspection laws such as SB 721 and SB 326 can drive repair projects that need clear existing-condition documentation. Title 24 remains a major issue for many residential and commercial permits. Historic properties may involve additional review, and owners using programs like the Mills Act should confirm local preservation requirements before altering character-defining features.
State law and local implementation can change, and cities interpret submittal checklists differently. Confirm the current requirements with your jurisdiction before relying on a general online guide.
When measured as-built drawings help most
Not every permit application starts with reliable original plans. Older California properties often have undocumented changes, missing archives, or field conditions that no longer match the last approved drawings. In those cases, measured as-built drawings can save substantial time by giving the design team and reviewers a dependable snapshot of what exists today.
As-built plans are especially useful when:
- You are remodeling an older house with unknown prior alterations.
- You are converting space and need accurate square footage.
- You are preparing an ADU, SB 9, or tenant improvement package.
- You need a clean base file for a designer, architect, or engineer.
- You are trying to avoid inconsistent dimensions across permit sheets.
- You have no trustworthy record drawings.
FastAsBuilt measures on site with laser equipment, then senior drafters prepare permit-ready CAD deliverables in PDF and DWG. That workflow is helpful when your electronic plan submission permit package needs a reliable existing set before proposed work is drafted. If you are ready to move, you can review options on our packages page or place an order at /order.
Common mistakes that delay electronic permit approval
Most delays are preventable. They happen when applicants treat e-plan submittal as a simple upload step instead of a documentation process with technical and administrative rules.
- Submitting plans based on rough tape measurements instead of verified field dimensions
- Leaving existing conditions unclear or inconsistent with the proposed scope
- Uploading the wrong version of a file
- Ignoring portal naming conventions
- Failing to cloud and date revisions
- Responding to only some reviewer comments
- Using unreadable scans or screenshots in place of proper PDFs
- Forgetting supporting documents such as authorization forms or energy paperwork
- Assuming one city’s checklist will match another city’s process
If your timeline matters, it is worth slowing down before the first upload. Good permit packages usually feel boring in the best way: complete, legible, consistent, and easy to review.
Frequently asked questions
Do all California cities use the same electronic plan submission permit system?
No. Many cities and counties use different software platforms, checklists, and upload rules. The overall permit process is similar, but the details can differ a lot. Always read your local jurisdiction’s current instructions before submitting.
Can you submit hand-drawn plans electronically?
Some small jurisdictions may accept simple hand-drawn residential plans for limited work, but they still need to be legible, complete, and to scale where required. For many projects, especially anything more than very minor work, professionally drafted plans are the safer choice for e-plan review.
Do you need existing plans before applying for a remodel permit?
Often, yes. Reviewers usually need to understand the current condition before they can evaluate proposed changes. If no reliable plans exist, measured as-built drawings can provide that baseline. Our article on as-built drawings for building permits explains where they fit.
How long does electronic permit review take?
There is no single timeline across California. Review speed depends on the city or county, project type, completeness of the submittal, and the number of review departments involved. For a broader look at timing, see how long building permits take in California.
