Permit Application Requirements

REQUIREMENTS FOR DOCUMENTS TO BE SUBMITTED WITH PERMIT APPLICATIONS FOR THE CONSTRUCTION OF ONE AND TWO FAMILY DWELLINGS

I. PURPOSE

The purpose of this document is to stipulate the minimum requirements for construction documents to be submitted for the purpose of obtaining residential building permits, so that all of the information needed (plans, documents and supporting information) will be provided at the time of the original application. As a result, the permit application may be processed more efficiently with fewer rejections for insufficient information. These requirements are specifically directed toward permits for construction of new residences, but are also applicable to other construction projects (additions, renovations, decks, etc.), as appropriate to the project.

II. REQUIREMENTS

1. All construction documents shall be coordinated to accurately reflect the specific materials and their intended arrangement when the proposed construction is complete. Unused options not applicable to the specific project shall be purged out of the construction documents prior to submittal. Drawings for mechanical, electrical, or plumbing systems, as well as cabinetry and trim details are not required and shall not be submitted.

2. Construction documents, with the exception of shop drawings (i.e., truss layout plans and engineered wood framing plans), shall be submitted in standard architectural scale (1/2”, 1/4”, 3/16”, or 1/8” per foot). Care should be taken when drawings are reduced to fit on a specific size of paper that they remain in a standard scale and that the details and the font remain legible.

3. All plan sheets within the construction documents shall have the same orientation and shall be numbered for easy reference. Reversed or “opposite hand” sets of drawings are permitted provided that all the sheets within the construction document set are consistently oriented.

4. All construction documents shall be legible, and in an easily readable font. Handwritten notes/changes shall be clearly readable and structurally pertinent or otherwise eliminated.

5. The construction documents with the jurisdiction’s original approved stamp must be on site for use by the inspector and contractor for all building inspections. Reproductions will not be accepted.

6. Two copies of a completed Building Permit Application form, and the following documents as applicable to the project:

A. A soil report when required by the Henrico County Soils Policy;

B. A plot (site) plan;

III. PLANS REQUIRING THE SIGNATURE AND SEAL OF A REGISTERED DESIGN PROFESSIONAL (RDP) LICENSED BY THE COMMONWEALTH OF VIRGINIA – (ENGINEER or ARCHITECT)

In accordance with the Virginia Uniform Statewide Building Code, a building official may require adequate technical detail be submitted to determine the code compliance of a RDP’s submittal. This may include calculations, stress diagrams or other essential technical date. Where a RDP seals plans for a specific structural element, or for the entire house, or submits a letter indicating that the plans have been reviewed for structural adequacy, engineering calculations are not required to be submitted unless requested by the Building Official.

The following plans require the signature and seal of a Registered Design Professional:

1. All retaining walls not laterally supported at the top and that retain in excess of 48 inches of unbalanced fill height.

2. Basement walls without both stone fill and drain tile in accordance with the Virginia Residential Code.

3. Tall walls that exceed 10 feet in height and 8 feet in width, except for the following:

A. Tall walls designed in accordance with the Virginia Residential Code.

B. Tall walls relying on engineered product designs in accordance with their listings contained in research reports prepared by an accredited agency.

4. Truss design drawings, except layout drawings

5. Brick veneer lintel details that do not comply with the provisions of the Virginia Residential Code. Note: All wood construction supporting brick veneer shall be designed for a maximum total load deflection of L/600.

6. Complex roof designs as defined by Section II, note 7 (“Stick-framed Roof Systems) of this document.

7. Structural braced wall systems that do not comply with the Virginia Residential Code, except for engineered product designs in accordance with their listings contained in research reports prepared by an accredited agency.
