- Repair and retain original porches.
- If rebuilding is necessary due to structural instability, reuse as much of the original porch and decorative details as possible.
- Assess the significance of a non-original porch before considering removing or altering it. A porch added to a building at a later date should not be removed simply because it is not original. It may have its own architectural or historic importance and is evidence of the evolution of the building.
- Original porch floors should be repaired or replaced to match the original.
- If a porch is missing, a new porch should be based on as much evidence as possible about theoriginal porch design, shap, size, location and details. Check the following sources for evidence:
- Old photographs
- Historic Sanborn maps
- Paint lines defining porch roof outlines
- Paint lines defining porch post design
- Remnants of the porch foundation
- Similar houses in the neighborhood (helpful but not always dependable)
- Oral descriptions from previous owners
- Where little or no evidence of the original porch remains, a new porch should reflect the typical porch form of the era while being identifiable as a recent addition not original to the building.
- Avoid alterations to historic porches, especially on primary facades.
- Avoid replacing original stone steps.
- Avoid replacing original wood floors with concrete.
- Avoid placing new porches in locations which never had porches, especially on significant elevations.
