Services in Torrance
Torrance's mix of post-war ranch homes and newer construction creates strong demand for ADU conversions, additions, and structural upgrades. Affinity provides PE-stamped drawings for Torrance's building department. For Torrance projects requiring more than structural, Affinity provides complete coordinated plan sets covering architecture, structural engineering, and MEP under one PE's oversight.
ADU & garage conversion
PE-stamped plans for Torrance ADU projects. Post-war ranch homes ideal for garage conversions. From $1,200.
Torrance has a mix of post-WWII ranch homes and 1960s–1970s construction. Many properties have raised foundations with cripple walls that benefit from seismic retrofitting, especially in Old Torrance and the Hollywood Riviera area.
Room additions & remodels
Structural engineering for Torrance additions including bungalow pop-ups. From $2,500.
Post-WWII Torrance homes may have raised foundations with cripple walls. Second-story additions trigger full foundation and lateral system evaluation.
Load-bearing wall removal
Beam and column sizing for safe wall removal in Torrance homes. PE-stamped plans for open floor plans. From $1,200.
Torrance ranch homes commonly have central bearing walls that also serve as shear panels. Removal requires both gravity and lateral system redesign per CBC.
