is not anchored to the concrete continuous footing. (See photo 9) 6. At the exterior (3 -sided) porch many of the perimeter support post and footings show signs of deterioration. In addition, the support posts are not tied to the 4x8 perimeter support beams and are not tied to the footings (see Photos 6 & 8). 7. At the crawl space below the floor, the interior 6x6 post that support 6x8 1st floor beams, there is.no tie at the top and bottom of the posts (see Photo 4). 8. The existing lateral load resisting shearwalls consist of 1x6 horizontal exterior siding. There is no plywood for shear (see Photo 1). 2nd Floor Level: -1. The main 4x6 post that support the porch roof do not have adequate connections to the beams above and below. Existing posts are only attached with toenails (see Photo 11). 2. The 6x6 corner post that support the porch roof do not have adequate connections to the beams above and below. Existing posts are only attached with toenails 3. Where the porch roof attaches to the side of.the main building walls, there is no tension tie to prevent the roof from pulling away from the building in a seismic event (see Photo 6). 4. The plywood at the small porch roof (northwest corner) is severely deteriorated (see Photo 7). 5. There is an existing abandoned brick fireplace that is likely not seismically tied to the floor diaphragm (see Photo 12). Since there is no chimney, we believe this was removed during a previous remodel. Note: this fireplace extends; down to the ground (into the crawl space), as such, , if the building were to be relocated it would be necessary to completely remove the brick fireplace. 6. The existing lateral load resisting shearwalls consist of 1x6 horizontal exterior siding. There is no plywood for shear (see Photo 1). Recommendations Based on our site observations of the existing condition of the building's structural components and our structural analysis, we recommend the following: 1It Floor Level: 1. We recommend replacing the exterior small porch at the southwest corner of the building. 2. Replace the (3) existing wood stairs at the exterior (3 -sided) porch with -new wood stairs and concrete footing at the base to allow proper anchorage of the stair stringers. 3. At the main building exterior foundation walls, we recommend adding''/z".CD-X plywood and "A35's" to provide a shear transfer mechanism from the floor to the existing 8" CMU stem walls. 4. At the two central main walls (on each side of the stairs), we recommend adding new continuous concrete footings and 2x6 cripple wall with, V2" CD -X plywood and anchor bolts. 5. At the small rear addition _(west side), we recommend adding %" CD -X plywood, sill anchor bolts and "A35's" to the existing wood cripple wall to provide a shear transfer mechanism to the existing concrete continuous footing. 6. At the exterior (3 -sided) porch at the center 4x6 and corner 6x6 post that support the porch roof, we recommend adding new 6x6 posts and footings below the deck. 7. At the crawl space below the floor, where the interior 6x6 post that support 6x8 lst floor beams, we recommend adding Simpson "128T" T-shaped ties to attach beams to post. 8. In order to provide lateral load resisting wall elements, we recommend adding.3/8" CD -X plywood at various exterior walls on the 15' level. The plywood can be installed. on the inside of the walls. 2nd Floor Level:
