Licenses and Inspections Commissioner, Robert D. Solivibile Sr., advises the citizens of Philadelphia to adhere to regulations concerning the construction and use of outdoor decks. By following procedures and hiring Licensed Contractors, the safety of your family and guest will be ensured.
Commissioner Robert D. Solvibile Sr., stresses the three keys to a safe deck are proper design, quality construction, and an on-going maintenance program. The Department of Licenses & Inspections reminds homeowners that permits are required for the construction of any decks constructed 12 inches or more above ground. The cost for the permit is $52.
Design and Construction
The purpose of obtaining a permit prior to constructing a deck is to ensure that the proposed design meets code requirements for structural integrity, safety, and proper location on your property. After obtaining a building permit, an L&I building inspector will visit the property to ensure that the contractor is following the approved plans.
- When hiring a contractor to build your deck, make sure he/she is properly licensed by the City of Philadelphia. Visit our website to find a
licensed contractor. Ask the contractor to show you the valid Contractor License or call the Department of Licenses and Inspections at 215-686-2490 to ensure the license is active. Remember to ask for references, insurance certificates, and a legal contract.
Before construction begins, insist on obtaining a copy of the permits and the L&I approved plans from your contractor. You or your contractor must also call the Building Inspector prior to starting work.
Decks constructed more than one story above grade and those with complex features must be designed by a registered professional engineer or architect to ensure structural adequacy.
More information concerning the Department's permit requirements can be found in the Department's publication, "Requirements for Decks (Simple Wood Decks for Single Family Dwellings)"
•If you know that your deck was constructed without permits you are encouraged to obtain the necessary permits immediately.
Maintenance
Although decks are typically constructed of pressure treated or naturally durable lumber, they are subject to rot and deterioration from exposure to water and sun. The Department of Licenses & Inspections recommends that you inspect your deck at least once per year for the following conditions:
- Signs of rotting or splitting wood particularly at the ledger board that attaches the deck to the house and at the base of the support columns.
- Loose bolts and connections especially those that attach the deck to the house. Tighten any loose bolts as necessary.
- Make sure there is no water collecting between the ledger board and the house. If necessary, install or replace the flashing.
- Guards and railings should remain sturdy and adequately connected to the framing. The Building Code requires that the guards extend at least 36 inches above the top of the deck, but 42 inches is preferred. The maximum spacing between guard spindles is 4 inches for a new deck. Many older decks have guard spindles spaced 6 inches apart and the Department recommends that you install additional spindles to reduce the size of the opening. Studies have shown that a small child is capable of squeezing through a 6-inch wide opening.
- Wooden decks should be coated at least once per year with a UV-resistant waterproofing product, in accordance with the product manufacturer's directions. Decks constructed of pressure treated or naturally durable lumber, such as redwood or cedar, are fine. Decks constructed of non-pressure treated pine should be replaced.
Commissioner Solvibile advises homeowners to use common sense when conducting events and parties on an elevated outdoor deck. Limit the number of occupants such that people have enough room to freely circulate. Small children should be supervised at all times. Finally, do not store heavy objects on the deck and avoid excessive vibrations and unusual loading conditions. If you are concerned about the condition of your deck, contact a competent home inspection agency or licensed engineer for a complete inspection. You may also contact the Department of Licenses and Inspections at 215-686-2463 and request an inspection.
