Deck Building Regulations and Permit Requirements
Regardless of deck height, one can’t build within 10 feet of the rear or 5 feet of side lot borders. Decks must be 3 feet from property lines. Rear decks limited by zoning. Deck permits ensure building to code. Guard rails must be 36 inches by code. Multi-family buildings fall under International Building Code. Generally no permit needed if under 100 square feet. Sun rooms and covered decks need permits.
Building a Deck Near the Property Line
How close to your fence can you build a deck? Decks must be 3 feet from property lines. Rear decks as close as 4 m to back and 0.6 m to side property lines are limited by zoning.
Permit Requirements and Applications
To apply for a deck permit, supply scale drawings of the framing plan view of your proposed deck. In some cases, you may be asked to also provide an elevation drawing to communicate more information about the deck.
Understanding Deck Permit Regulations
Decks less than 30” high do not require a Building Permit. For decks over 30” high or having a roof, a Permit is required. You need a permit to build a deck more than 2 feet above adjacent grade.
Consequences of Building Without a Permit
Doing work without a permit will result in an enforcement action and you may be subject to fines up to $1,000 per day. A permit is required if attached to house or over 30 inches high. If freestanding under 30 inches and 200 square feet, likely no permit needed.
