What happens if I renovate my NB kitchen without a building permit?

Renovating without a required building permit in New Brunswick creates serious legal, financial, and safety risks that far outweigh any perceived savings in time or money. The consequences can follow you for years, particularly when you try to sell your home or file an insurance claim.

Insurance implications are arguably the most dangerous consequence. If unpermitted electrical work causes a fire, or unpermitted plumbing causes water damage, your home insurance company can deny your claim entirely. Insurers routinely investigate the cause of losses, and if they discover that the work was done without required permits and inspections, they have grounds to void coverage. On a kitchen fire claim that could be worth $50,000 to $200,000 or more, losing insurance coverage is financially devastating.

Selling your home becomes complicated with unpermitted work. During a real estate transaction in New Brunswick, the buyer's lawyer will search municipal records for permit history. If your kitchen renovation involved obvious electrical, plumbing, or structural changes but no permits were pulled, the buyer or their lawyer may demand that you obtain retroactive permits and inspections — which could mean opening up finished walls and ceilings so an inspector can see the wiring and plumbing. Retroactive permitting and remediation can cost $5,000 to $15,000 or more, and it often delays or kills the sale entirely. Some buyers will simply walk away from a home with unpermitted renovations.

Municipal enforcement varies across New Brunswick. Cities like Moncton, Fredericton, and Saint John have building inspection departments that can issue stop-work orders, fines, and orders to remove unpermitted work. If a neighbour reports the renovation or an inspector notices work being done during a routine visit, you could face penalties. In rural areas under Regional Service Commissions, enforcement may be less proactive, but the legal requirements are identical.

The Safety Factor

Safety is the fundamental reason permits exist. Kitchen electrical and plumbing systems are the most demanding in any home. Improperly wired circuits can cause fires — kitchens have the highest fire risk of any room. Incorrect plumbing can lead to sewage gas leaks, water contamination, or flooding. Structural modifications done without engineering can cause walls, floors, or roofs to sag or fail over time. The rough-in inspection catches these problems before they are hidden behind drywall.

The NB Building Code requires a minimum of two 20-amp small appliance circuits for countertop outlets, GFCI protection near sinks, dedicated circuits for major appliances, proper drain venting, and adequate structural support. Without inspections, there is no independent verification that any of this was done correctly.

The cost of doing it right is minimal. Permit fees in New Brunswick range from $75 to $300 — a fraction of even a basic kitchen renovation budget. The inspection process adds 1 to 2 weeks to your timeline at most. Compare that to the potential cost of denied insurance claims, failed home sales, or unsafe conditions, and permits are clearly worth the small investment. Any reputable kitchen contractor in New Brunswick will pull the required permits as standard practice.
