When we receive a plan review with red markups, it can feel confusing, especially if we are applying for a permit for the first time. We understand how stressful it can be when approval depends on comments that are not always easy to interpret.
We always guide our clients with one simple mindset. Red markups are not rejections. They are clear instructions that help us fix issues and move the project forward smoothly.
In this guide, we explain how to understand red markups from a city plan reviewer in a simple and practical way so we can handle revisions with confidence.
What Are Red Markups in Plan Review
Red markups are comments or corrections added by a city plan reviewer on submitted drawings. These notes highlight what needs to be fixed before approval is granted.
We treat every markup as a checklist item. Each comment tells us exactly what is missing or incorrect. If even one point is ignored, it can delay the approval process.
These markups usually appear on:
- Site plans
- Floor plans
- Elevation drawings
- Supporting documents
Understanding these comments correctly is the first step toward faster approval.
Why City Plan Reviewers Use Red Markups
City reviewers follow building codes and zoning rules to ensure safety and compliance. Their job is to make sure every project meets legal and structural requirements.

From our experience, most delays happen because applicants misunderstand the comments rather than because the project is complex.
Common reasons for red markups include:
- Missing dimensions
- Incorrect setbacks
- Zoning issues
- Incomplete labels
- Missing technical details
When we understand why these comments are given, it becomes much easier to respond correctly.
Understanding site plan rejection reasons can help prevent repeated corrections and delays.
How to Read Red Markups Step by Step
To properly handle how to understand red markups from a city plan reviewer, we always follow a structured approach. This helps us avoid confusion and reduces revision cycles.
Step 1 Review All Comments First
We start by reviewing every comment on the plan before making any changes.
Some comments are connected. Fixing one issue may solve another. That is why we always look at the full picture first instead of working randomly.
Step 2 Identify the Type of Comment
Not all comments require the same level of work. Some are simple corrections, while others need deeper changes.
We usually categorize comments into:
- Missing information
- Code related issues
- Clarification requests
- Required revisions
This helps us plan the work efficiently.
Step 3 Match Comments With Drawing Areas
Each markup refers to a specific part of the drawing.
We carefully match every comment with its exact location on the plan. This prevents mistakes and ensures accurate updates.
Step 4 Check Code References
Sometimes reviewers include code references. These are very important.
We always verify the code before making changes. Skipping this step can lead to incorrect revisions and further delays.
Step 5 Create a Correction Plan
Before editing, we organize all comments into a clear action list.
This ensures that nothing is missed and helps us complete revisions in a systematic way.
Common Red Markups and What They Mean
Many red markups appear repeatedly across different projects. Recognizing them saves time and reduces confusion.
Here are some common examples and what they indicate:
- Add property setbacks
This means required distances from property lines are missing - Label all structures
Every building or feature must be clearly identified - Provide scale
The drawing must include proper measurement reference - Show drainage direction
The reviewer needs to confirm water flow on the site - Revise dimensions
Measurements are incorrect or incomplete
We always focus on understanding the meaning behind each comment so that corrections are accurate the first time.
Mistakes to Avoid When Responding to Red Markups
Many applicants face delays because of simple mistakes that can easily be avoided.
We always recommend avoiding the following:
- Ignoring small comments
- Guessing instead of checking requirements
- Submitting partial revisions
- Updating only one section of the drawing
- Missing any comment in the response
Even one missed detail can result in another review cycle, which increases time and cost.
If your plan has already been rejected, you can fix rejected site plan using a structured correction approach.
