July 7, 2023 RE: Ruiz Residence 1105 Toyath St Austin, TX 78703 To Whom it May Concern, This letter is being submitted to bring attention to the structural condition of the residence referenced above. An on-site observation of the structural elements was conducted by this office producing some key take aways as follows: 1. Foundation: The footings observed consist of cedar stumps at the interior and unreinforced grouted masonry at the perimeter all bearing on the surface of the existing grade. Large deflections were observed in the wood floor beams and joists with large fluctuations in the levelness of the floor throughout the house. 2. Load Bearing Walls: The majority of the perimeter walls were observed to be 2x2 studs which are insufficient for gravity or lateral loads posing a life safety risk in the event high roof live loads and/or wind loads. The door and window headers were not able to be observed, however it is reasonable to assume those would be insufficient as well given there is only a 2 inch width for the beams, trimmers and king studs. 3. Lateral bracing elements: The sheathing type and attachment, top plates and roof diaphragm attachment are not up to code. The structure is also not properly anchored to the ground, not having proper footings or hold downs. 4. Roof framing: While the roof framing has been replaced since the initial construction of the home, the rafters which are 2x4’s at 24” o.c., are still insufficient for the spans and would need to be reinforced with tie downs to the top plate. max@statixeng.com  Page 2 July 7, 2023 Ruiz Residence In conclusion, the vast majority of this home’s structure does not meet the provisions of the International Residential Code and potentially poses a safety risk to occupants. In light of these findings, I recommend the following course of action: 1. Complete Demolition: The existing residence should be carefully demolished in accordance with City of Austin regulations and The Historical Commissions guidelines to ensure the preservation of any salvageable historical elements. 2. Structural Replacement: A new structure should be designed and constructed in compliance with current building codes and standards, ensuring the incorporation of appropriate historical architectural elements to maintain the district's character.
