Florida Code Calculators and Pre-Submittal Report Tools

EZCodeCalcs helps permit expediters, business owners, contractors, designers, and plans examiners understand common Florida code requirements before plans are submitted for permit review.

Know What May Be Required Before You Submit

Many permit problems start before the permit application is ever submitted. A business owner may lease a space without knowing if the new use creates higher occupant load, plumbing fixture, ventilation, exhaust, accessibility, or alteration concerns. A permit expediter may be asked to submit documents without knowing what the building department may ask for. A designer may need a quick way to organize the basic code information before preparing drawings.

EZCodeCalcs is built to help organize those questions early. These tools do not replace the authority having jurisdiction, a licensed design professional, or a full code review. They help identify common code triggers and create clear worksheets that can be used before permit submittal.

Permit Expediters

Use these tools to better understand what information may be needed before submitting a permit package.

Business Owners

Check whether a new tenant space or change in use may create additional code requirements.

Designers

Use the calculators as a starting point for organizing occupant load, plumbing, ventilation, and use data.

Contractors

Review common permit-related issues before work begins or before documents are sent for review.

Start with a Free Calculator

Choose the calculator that matches the issue you are trying to understand. Each calculator is designed to help organize basic code information before permit submittal.

Occupant Load Calculator

Estimate occupant load using the occupancy, use of space, and square footage.

Useful when reviewing tenant spaces, restaurants, offices, assembly areas, and changes in use.
Open Calculator

Plumbing Fixture Calculator

Estimate minimum plumbing fixture requirements based on occupancy and occupant load.

Useful when checking restroom counts, tenant buildouts, and occupancy changes.
Open Calculator

Mechanical Ventilation Calculator

Estimate outdoor air and ventilation requirements for common commercial spaces.

Useful when reviewing restaurants, offices, retail spaces, salons, and assembly areas.

Ventilation Table 403.3.1.1 Tool

Use your Mechanical Code book and enter the required table information to determine the required mechanical ventilation for your project.

Best for users who want to work directly from Table 403.3.1.1 and organize the ventilation calculation.

Need a Project Worksheet Report?

Like what you see in the calculator tools? If your project needs a more organized worksheet, comparison, or written explanation, you can request a PDF worksheet report. These reports are designed to organize basic project information in a clear format for discussion, planning, or pre-submittal preparation.

Occupant Load Worksheet Report

A worksheet report organizing occupant load information based on the occupancy, use of space, square footage, and customer-provided project information.

Best for tenant spaces, restaurants, offices, assembly areas, and projects where occupant load needs to be organized.
Order Report

Plumbing Fixture Worksheet Report

A worksheet showing estimated plumbing fixture information based on the submitted occupancy, use, occupant load, existing fixtures, and proposed fixtures.

Best for restaurants, offices, assembly areas, retail spaces, salons, and tenant buildouts.
Order Report

Mechanical Ventilation Worksheet Report

A worksheet showing basic ventilation information that may be needed before permit submittal.

Best for spaces where outdoor air, exhaust, makeup air, or occupancy changes may be an issue.
Order Report

Use / Alteration Pre-Check Worksheet Report

A worksheet report used to compare the existing condition with the proposed project so possible occupancy, use, alteration, plumbing, ventilation, exhaust, or accessibility concerns can be identified early.

This is not a plan review. It is a pre-check worksheet to help owners, permit expediters, contractors, and designers see whether there may be areas to review before moving forward.

What Are We Pre-Checking?

The Occupancy / Use / Alteration Pre-Check Report is intended to help organize basic project information before permit submittal. It does not approve a project, replace a licensed design professional, or perform an official plan review.

Change of Occupancy

A change of occupancy generally means the proposed project changes the occupancy classification of the space or building. This may create additional code requirements.

Change of Use

A change of use generally means the activity or function of the space changes, even if the occupancy classification may appear to stay the same. The new use may still affect occupant load, plumbing, ventilation, exhaust, accessibility, or other requirements.

Alteration

An alteration generally means work is being performed on an existing building, system, space, or element. The level and type of work may determine which existing building requirements apply.

Pre-Check Purpose

The purpose is to help identify possible areas that may need attention before submittal, not to issue approvals or replace the AHJ, architect, engineer, or licensed designer.

How EZCodeCalcs Helps

1. Identify the Existing and Proposed Use

Start with the basic project information. If the project involves an existing building or tenant space, the previously permitted occupancy and use should be included. This information may need to be verified by the landlord, prior permit records, or the authority having jurisdiction.

2. Review Common Code Triggers

The tools and worksheet reports help organize common issues such as occupant load, plumbing fixture counts, mechanical ventilation, exhaust, accessibility concerns, and possible use or alteration concerns.

3. Prepare Before Submittal

Use the results to ask better questions, prepare better information, and reduce surprises before the permit package is submitted for review by the AHJ.

Learn the Code Before It Becomes a Permit Problem

Have a code question or want a clearer explanation of a common permit issue? EZCodeCalcs can help organize the question, review the applicable code topic, and provide a written PDF explanation in simple language.

Code Explainer PDF
