How much does a retroactive deck permit cost in Moncton NB?

Getting a retroactive building permit in Moncton for an existing deck typically costs the same as a standard permit — around $100–$300 in permit fees — but the real cost comes from any required upgrades to bring the deck up to current code.

The City of Moncton's Building Inspection department handles retroactive (or "after-the-fact") permits the same way they handle new construction permits from a fee standpoint. The permit fee itself is based on the value of the construction, so a modest deck might land at the lower end of that $100–$300 range. However, the bigger financial consideration is what happens after the inspector sees the deck.

When you apply for a retroactive permit, a building inspector will assess whether the existing structure meets current NB Building Code requirements. If it doesn't — and many older decks don't — you'll be required to make corrections before the permit can be approved. Common issues on older Moncton decks include footings that don't reach the 1.2 metre frost depth required for the area, ledger boards that were nailed rather than lag-bolted, missing ledger flashing, or railings that don't meet the 900mm minimum height with proper 100mm baluster spacing. Structural corrections like these can run anywhere from $1,000 to $5,000+ depending on what needs to be fixed.

The process in Moncton generally works like this: You contact the City of Moncton Building Inspection department directly, submit drawings or as-built plans of the existing deck, pay the permit fee, and then schedule an inspection. The inspector will identify any deficiencies in writing, and you'll have a set timeframe to correct them before a final inspection and approval.

A few practical tips before you apply. First, take detailed measurements and photos of your deck — you'll likely need a simple site plan showing the deck's dimensions, distance from property lines, and how it attaches to the house. Second, if you suspect the footings are shallow or the structure has issues, it may be worth having a local deck contractor assess it before you apply, so you're not caught off guard by the scope of required repairs. Third, don't avoid the permit — unpermitted decks can create serious problems when selling your home, and liability issues if someone is injured.

This is definitely a situation where getting a professional involved makes sense. A qualified deck builder can assess your existing structure, identify what will and won't pass inspection, and give you a realistic picture of upgrade costs before you start the permit process.
