Soft-Story Seismic Retrofit – City of West Hollywood

Overview

The City of West Hollywood officially implemented a seismic retrofit program on April 17, 2017. This program was created to reduce earthquake-related risks and improve life safety for occupants of commercial and multifamily buildings throughout the city. Ordinance 17-1004 outlines the mandatory requirements for strengthening existing wood-frame buildings that have soft, weak, or open-front walls. It also includes requirements related to cripple walls and sill plate anchorage in older wood-frame structures. The ordinance went into effect on April 1, 2018.
  • Priority I: Buildings with 16 or more dwelling units
  • Priority II: Buildings with 3 or more stories and fewer than 16 dwelling units
  • Priority III: Buildings that do not fall under Priority I or Priority II

Frequently Asked Questions

Does every older building in West Hollywood need a retrofit?
No. The ordinance applies to wood-frame buildings with soft, weak, or open-front wall conditions, typically multi-story structures with tuck-under parking or large ground-floor openings. The screening report is what confirms whether your specific building requires retrofit.
What’s the first step?
A screening report prepared by a California-licensed Civil or Structural Engineer. This must be submitted within 1 year of your Notice.
Can my building be exempt?
Possibly. The screening report evaluates whether your building meets the SWOF criteria or whether a prior retrofit already satisfies current requirements.
Who’s allowed to prepare the screening report and retrofit plans?
California-licensed Civil or Structural Engineers.
What happens if I miss a deadline?

The City can issue fines, pursue enforcement actions, and record violations against the property. Extensions are limited and must be justified.

Are there tenant protections I need to be aware of?
Yes. West Hollywood has a rent stabilization program and specific rules governing tenant notification and habitability during construction. Work with the City’s Rent Stabilization Division for the current requirements that apply to your project.
Under which priority group does my building fall?
Priority I covers buildings with 16 or more dwelling units. Priority II covers buildings with 3 or more stories and fewer than 16 units. Priority III covers everything else that qualifies under the ordinance.
