Initial analysis

735 Clayton Street is a three-story multi-family residential building located in the Haight Ashbury neighborhood, built in 1908 and currently owned by Golden Properties LLC. The building has undergone significant changes over the past decade, particularly regarding unit configuration and compliance issues. In 2013, an illegal third unit was identified and subsequently removed, followed by numerous permits and renovations to modify the building's layout. Most recently, in 2022, there were several complaints about work exceeding permitted scope, involving the conversion of storage spaces and improper demolition activities. The building has a history of compliance challenges, starting with multiple violations in 2009-2010 related to lead paint concerns, interior maintenance issues, and safety concerns including fire escape problems and gas utility shutoff requirements. A significant cluster of violations occurred in 2012-2014, including overcrowding complaints, improper fire separation, inadequate fire protection, and unapproved electrical/plumbing modifications.

The property has seen substantial renovation activity since 2013, including the conversion of storage spaces, heating system upgrades, and various kitchen and bathroom remodels. Most of the recent building permits have been properly processed and completed, with the exception of some complaints in 2022 regarding work beyond permitted scope. Historical violations were addressed, with most being abated by 2011. The building's most recent major improvements include a 2022 project to convert unconditioned storage space into residential living areas, though this work prompted additional complaints about unauthorized modifications. The property has been subject to multiple inspections and evaluations by housing authorities, leading to various compliance requirements being established and subsequently met, though not without some ongoing concerns about adherence to permitted work scopes. While many historical compliance issues have been resolved through proper permitting and renovations, the building's recent history shows some pattern of work being performed beyond approved scopes, though these instances appear to have been addressed through subsequent permits.

Risk rating

How 735 Clayton St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
