Addition/Alteration (ALTC) - Commercial

A commercial addition/alteration permit is required for the following projects:

  • Interior Alterations
  • Interior alterations for an existing tenant or owner
  • Interior alterations with additional square footage (NOTE: if your project does not include interior alterations you should apply for a Commercial New record)
  • Interior demolition (with or without plans)
  • Metal stud only
  • Installation of modular furniture
  • New tenant layout

For detached commercial structures, apply for the Commercial New record.

To determine whether your permit application requires an associated grading plan, visit our Land Disturbance 101 webpage.
 

This information is the most common for how to obtain the necessary approval for your project and is not representative of all the conditions you may encounter.

 

WHO SHOULD APPLY?

Property owners may obtain permits in their own name, however, it is strongly recommended a properly licensed contractor pull the permits as the responsible party so the county can better assist in gaining compliance for defective work.

 

PLAN AHEAD

Before submitting, ensure you are aware of all applicable regulations and conditions that could affect your project to avoid surprises during the review process. Some of those factors include:

  • Zoning Information
  • Design Codes and Standards
  • Do I Need to Hire a Registered Design Professional (RDP)?
  • Floodplains
  • Resource Protection Areas (RPA)
  • Grading/Site Plans
  • Parking Tabulation
  • Types of Soils and Problem Soils
  • Researching Site Conditions

To get a detailed description about each regulation and condition, visit our Plan Ahead page.

Associated Trade Permits

If your project includes electrical, plumbing or mechanical (often referred to as “trades”) work, separate trades permits may be required. When associated with the same project, the trades permits should be related to the main building permit (the “parent” permit) as “child” permits. 

  • Electrical (ELEC) and Plumbing (PLBC) Permits
    These permits can be obtained after the building permit has been issued. Plans are not required. Identify that there is a Parent Permit in the Step 2: Application Detail.

  • Mechanical (MECHC) Permits
    These permits are applied for in the same manner as the electrical and plumbing permits. If you are installing a new HVAC system, you will need to submit an Air Leakage/Duct Leakage Test form online. It must be reviewed/approved prior to calling for a final inspection.

 

Building Inspections

Once the permit is issued and you begin construction, you are required to obtain inspections from the county for your project. The county must be notified when the stages of construction are reached that require an inspection. For more information, see our inspections webpage.

Occupancy

A Certificate of Occupancy (Non-RUP record type) is the occupancy permit issued for a commercial space after all permits receive final inspections and all conditions are met. Non-RUP applications are applied for in PLUS.
