Design Standards for Exterior Entrances and Porches 1. Identify, retain, and preserve character-defining architectural elements and details of entrances, porches, porte cocheres, and balconies including but not limited to form and configuration, roofs, cornices, piers, lattice, flooring, porch supports, columns, capitals, plinths, ceilings, rails, balusters, steps, brackets, and other decorative trim work. 2. Protect and maintain exterior entrances and porches, their materials, details and features. 3. Repair exterior entrances and porches using accepted preservation methods, including patching, consolidating, reinforcing, or splicing only the deteriorated portions and retaining as much original material as possible. 4. Replace deteriorated exterior entrances and porches and their details and features only if it is deteriorated beyond repair. Replace only the deteriorated portion matching the original in design, scale, size, shape, pattern, composition, color, texture, finish, and materials. 5. If a porch feature or detail is missing, replace it, based on documentary or physical evidence, with features matching as closely as possible in design, scale, size, shape, pattern, composition, color, texture, finish, and materials. 6. It is appropriate to paint all visible entrance and porch features. Treated wood shall be painted or sealed following an adequate drying period (approx. 6 months). 7. It is appropriate to remove existing non-historic porch enclosures to restore the original appearance of an open porch.
8. Damaged wood floors may be repaired in-kind or completely replaced with tongue-and-groove flooring or 5/4" decking boards. It is inappropriate to use concrete, composite, or cementitious fiber board as a replacement material for historic wood porch flooring. 9. It is inappropriate to introduce new exterior entrances, porches, and details. Replication of missing entrances and porches shall be based on documentary or physical evidence. 10. Porches that were historically without balustrades and now require them to meet a code requirement may install a porch balustrade with a top and bottom rail and vertical balusters placed 6" on center and constructed of wood or wrought iron and simple in design so that it does not portray a false sense of history. 11. It is inappropriate to enclose a front porch or balcony. If a side or rear porch enclosure is necessary, it shall be of transparent materials such as glass or screen wire. Installation shall be recessed behind the railing and columns.
