GENERAL PORCH NOTES
√ For specific side yard requirements for a porch, contact the Zoning Department, City Hall,
(319) 356-5120. A general rule of thumb is a minimum of five (5) feet from any side property
line.
√ All porch framing members, decking and railing must be of approved naturally-durable or
pressure treated wood.
W:\wpdata\HISBLG\Guidelines '08\porch-08.doc 3
√ For use of pre-fab roof trusses—submit truss specification sheets sealed by an Iowa
registered engineer to the Building Inspector at the time of inspection. Specification sheets
must be specific and correspond to actual trusses used—any truss modification requires
submittal of revised sealed specification sheets.
√ All exterior walls, regardless of porch size, closer than five (5) feet from the side property
lines are required to have a one (1) hour fire rating. Fire rating on walls are usually obtained
by use of a masonry/brick or 5/8” thick Type X fire rated gypsum board on both sides of
stud.
