Seismic retrofit engineering involves designing structural modifications that improve a building's ability to resist earthquake forces, particularly addressing soft-story vulnerabilities in older apartment buildings. In West Hollywood, where mandatory retrofit ordinances affect hundreds of multi-family buildings, professional engineering is essential for compliance and life safety. Our California-licensed Professional Engineers with over 20 years of experience design seismic retrofits throughout West Hollywood and Los Angeles.

West Hollywood's distinctive architectural character includes numerous 2-3 story apartment buildings from the 1960s-1970s with ground-floor parking—the classic soft-story condition that poses serious earthquake risks. The city's mandatory retrofit ordinance requires property owners to address these vulnerabilities with engineered solutions.

West Hollywood's mandatory seismic retrofit ordinance requires owners of vulnerable soft-story buildings to complete structural retrofits within specified deadlines. Our licensed Professional Engineers design compliant retrofit solutions that satisfy city requirements while minimizing cost and tenant disruption.

**Phased Implementation:** The ordinance established compliance deadlines based on building priority tiers. Contact West Hollywood building department for current deadline status and your building's specific requirements.

Soft-story retrofit engineering in West Hollywood typically takes 6-10 weeks from evaluation to permit-ready plans. Our licensed Professional Engineers design retrofit solutions using steel moment frames, shear walls, or hybrid systems to strengthen vulnerable ground-floor conditions.

**West Hollywood Specifics:** We understand WeHo's building stock, typical construction methods, and building department preferences.

West Hollywood seismic retrofits typically use steel moment frames, plywood shear walls, or hybrid systems depending on building configuration, tenant impact considerations, and budget. Our licensed Professional Engineers select optimal systems for each building's specific conditions.

**Typical West Hollywood Application:** Moment frames at garage openings maintain parking function while providing seismic resistance.

Seismic retrofit engineering in West Hollywood typically costs $8,000-$25,000 for design services, depending on building size and complexity. Construction costs range from $100,000-$400,000+ depending on building scope and retrofit system selected.

| Building Size | Engineering Cost | |---------------|-----------------| | 3-16 units | $8,000-$12,000 | | 17-30 units | $12,000-$18,000 | | 30+ units | $18,000-$25,000+ |

| Building Type | Retrofit Construction | |---------------|----------------------| | Small (under 20 units) | $100,000-$200,000 | | Medium (20-40 units) | $200,000-$350,000 | | Large (40+ units) | $350,000-$500,000+ |

Seismic retrofitting in West Hollywood provides life safety protection, property preservation, ordinance compliance, and potential property value enhancement. The investment protects tenants, avoids fines, and positions properties well for sale or refinancing.

**Is my West Hollywood building subject to the retrofit ordinance?** Buildings with 3+ stories and ground-floor parking or commercial space, built before 1978, are typically covered. Contact WeHo Building & Safety for official determination.

**What happens if I miss the retrofit deadline?** Non-compliant buildings face daily fines, potential rent restrictions, and may have difficulty selling or refinancing. Compliance is mandatory, not optional.

**Can tenants remain during retrofit construction?** Usually yes. We design retrofits to minimize tenant disruption, and most work occurs in common areas and parking structures.

**How long does retrofit construction take?** West Hollywood soft-story retrofits typically take 3-6 months for construction, depending on building size and retrofit scope.

**Are there financing options for retrofits?** Yes, PACE financing, seismic retrofit loans, and other programs may be available. Some costs may be passed through to tenants per local regulations.

**Will retrofitting increase my property taxes?** Seismic retrofitting is generally excluded from reassessment under California law, meaning it shouldn't increase your property tax basis.
