GENERAL NOTES
AutoCAD SHX Text
Zoning Permit. You must bring a copy of your house location plan that shows the proposed location of the deck, drawn to the same scale as the plan. Show the side yard and rear yard distances (setbacks from property lines) on the plan. No changes shall be made to approved plans without prior approval from the Building Construction Review Branch. Approved deck plans shall not be used for supporting hot-tub installation, without re-submission for review. All metal connections, bolts, joist hangers, etc. shall be galvanized or corrosive resistant. All lumber shall be pressure treated Southern Pine, grade #2 or better. Building permit is not required if all portions of the top of the deck's flooring is within 16.5 inches from all portions of the top of the deck's flooring is within 16.5 inches from portions of the top of the deck's flooring is within 16.5 inches from the finished grade unless it carries structural load, e.g. hot-tub. All decks require zoning permit. Provisions in the Prince William County Zoning Ordinance for at-grade decks and patios differ from those in the Building Code. In the Zoning Ordinance, the standards are as follows: "Patios, decks, walkways, steps and driveways constructed no higher than eight (8) inches above existing grade of the contour of the land where located may encroach within any setback provided that no permanent above-grade affixed structures such as railing, planters, benches, roofs or other appurtenances are installed." Column spacing and joist spans shown are maximum. Smaller decks may be constructed utilizing the same structural members. The typical residential deck design shall be strictly adhered to. All deviations from these drawings shall require an independent set of design documents to be prepared and submitted to the Building Construction Plans Review Branch for review. If a proposed deck does not conform to these typical design details, a custom design can be submitted to the Building Construction Review Branch. Submit two (2) copies of the design, including framing plans, cross sections, and stringer details for review. Material requirements are as follows: Please go to www.treatedwood.com/products/preserve/ for a list of hardware manufacturers that recommend hardware for use with Alkaline Copper Quaternary (ACQ) treated wood. Decking composed of foreign lumber, plastic or manufactured materials may be substituted only when the product has an approved evaluation report from ICC-ES or from an accredited testing laboratory.

Requirement hot-dipped zinc galvanized, stainless steel, or approved for use with ACQ, CA, or CA-B hot-dipped galvanized with a 1.85 oz/sf of zinc (G-185 coating) or Stainless Steel (type 304 or better) Examples "Zmax" from Simpson Strong-Tie "Triple Zinc" from USP copper, stainless steel, silicon, bronze, or UV-resistant plastic , and hot-dipped galvanized steel with a G30 zinc coating
AutoCAD SHX Text
Notes: In all cases, electroplated galvanizing is NOT acceptable. ICC Evaluation Report and testing data are required to substantiate decay resistance of plastic.
