9170 West Thrasher Avenue Accessory Structure - ZA-2021-10815-ZV-ZAD-ZAA

The project at 9170 West Thrasher Avenue in Los Angeles involves the legalization of an existing 385-square-foot accessory structure used to house mechanical equipment and support roof-mounted solar panels, with no new construction, alterations, or demolitions proposed. The structure, rising 13 feet above a covered patio to reach a total height of 30 feet, complies with the 36-foot maximum envelope permitted for hillside lots in the RE15 zone featuring roof slopes of 25 percent or greater. The property includes a two-story single-family dwelling of approximately 5,594 square feet, a three-car garage, and a swimming pool and spa. A historical lot cut from January 15, 1964, resulted in a lot area of 5,298 square feet, which is below the current RE15 minimum requirement of 11,000 square feet but is legally recognized due to its prior establishment. Grading conducted in the area was previously approved under LADBS permit 09020-20000-02161, with 58 cubic yards of soil excavated and no fill imported, and a pre-inspection was completed in August 2018 under permit 18030-10000-05207. No trees are proposed for removal. The application requests multiple zoning variances and adjustments, including a reduction of the northerly side yard setback and rear yard setback to zero feet, an exception to the required road access standards, and approval for excessive residential floor area and lot coverage due to the structure’s presence. Compliance with local regulations is supported by geotechnical reports labeled RC-GEO-1 through RC-GEO-6, which confirm site stability and mitigate risks related to expansive soils and seismic activity. The project qualifies for categorical exemptions under the California Environmental Quality Act (CEQA), specifically Classes 1 and 3, due to its nature as an existing facility with no significant environmental impact. The City of Los Angeles Department of City Planning and Department of Building and Safety oversee permitting and approval, with inspections required at the site and final acceptance administered through city agencies. Legalization is contingent upon verification of prior compliance with the LADBS grading permit, adherence to the Hillside Ordinance, fire hazard mitigation standards under LAMC Section 57.4906.5.2, and proper drainage and sewer management per
