Deck Permit

Permit Description

A Deck is generally a wooden platform built above the ground and connected to the main building. Above a certain height, it is enclosed by a railing for safety. Access may be from the house through doors and from the ground by stairs. This permit is specifically for Single-Family and Two-Family Dwellings.

Deck Permit FAQs

I own a single-family home and am constructing a deck on my property.  What application type should I use to accurately describe my project?
If one level, and under 500 square feet, you may now select from the application Service Type, Deck Permit, under General Information. This permit is applicable for single- and two-family dwellings.

Am I required to identify a design professional in the permit application during the submission process?
If you are using the Deck Guide, a design professional is not required to be identified in the application during the submission process, when applying for a one-level residential deck with dimensions totaling 500 square feet or less, on a single– or two-family dwelling.

What is the permit fee for the new Deck Permit?
The Deck Permit fee is  based upon the cost of the construction.  For projects with a construction cost:

  • Of less than $500, the permit cost is $36.30
  • Between $500 - $1,000, the permit cost is $71.50
  • Between $1,001 - $1,000,000, the permit cost is calculated as ($30.00 +(2% of construction value $1001 - $1,000,000)) + 10% and ranges between $55.02 - $22,033

I am constructing a deck that will not be for a single-family or two-family dwelling, it is for a multi-unit building.  Must I identify the design professional in the permit application?
Yes, for larger residential projects, a design professional is required to be identified in the permit application during the submission process.  Also, rather than submit an application for a Deck Permit, an application for an Occupied Roof Deck, a Two-Story Deck or a Multi-Story Balcony/Deck Permit must be submitted.
