Key information

A deck needs Building and Development permits when attached to the main building, used to access its door, or intended for public congregation. Detached decks outside those conditions may instead follow accessory-structure rules.

When and where a permit applies

Replacement, construction and modification are all covered. A restaurant patio is an example of public-congregation use. Confirm the route for an unattached backyard deck with Planning.

The deck follows dwelling setbacks with specified permitted encroachments. The page allows a 2 m encroachment into required front, rear and flankage yards. Its R2 example reduces a 5 m rear yard to 3 m;that example is not a universal setback for every zone.

Plans and engineered designs

Provide a site plan showing boundaries, buildings, deck and property-line distances. Add a detailed construction sketch and the helical-pile engineering document if used for support.

A hot-tub load, non-prescriptive structural support or public-congregation deck can need a New Brunswick structural engineer’s sealed drawings. Any roof, gazebo or other added structure also needs appropriate drawings.

Fee calculation and code changes

The city estimates deck construction value at $15/sq.ft., or $20/sq.ft.with a roof. The building fee is $8 per $1,000 of estimated cost, with a $25 minimum, plus the applicable Development Permit fee. These are fee-assessment inputs, not a contractor’s construction quote.

The city page warns new 2025 national building/energy codes take effect January 1,2027. Ask which requirements govern your submission before reusing older standard drawings.
