Rent & eviction protection

Is 1538 Clay St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1916
2 or more units
12 units
Property type
Multi-Family Residential

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1916
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The 12-unit, three-story apartment building at 1538 Clay Street in Nob Hill, built in 1916 and currently owned by Wong Family Revocable Trust 2019, has undergone significant renovations and faced several serious incidents over the past decades. Most notably, in June 2022, the building experienced substantial damage when a vehicle crashed into it, rupturing gas lines and damaging the garage and lobby walls, resulting in temporary building closure and requiring emergency structural repairs costing $30,000. The building has been actively undergoing improvements, including the recent construction of alcoves for electrical and gas meters (approved in September 2024) and plumbing work for gas lines in all units (November 2024). A significant renovation project in 2019-2022 converted the first floor and garage area into three ADUs, involving extensive plumbing and electrical work, including new bathrooms, kitchens, and three 70,000 BTU furnaces.

The property has completed mandatory soft-story seismic retrofit work (Tier 3) and has addressed several safety concerns over the years, including a series of building violations in 2001 related to fire safety and security, all of which were abated. The building experienced serious plumbing issues in 2003, with multiple complaints of sewage backups affecting several units and common areas. More recent complaints from 2024 focused on fire escape maintenance and compliance issues, which were subsequently addressed. While there have been periodic maintenance and infrastructure improvements, including roof work in 1994 (now expired), and several 311 calls regarding building maintenance issues, the property has generally maintained active compliance with building codes and safety requirements, as evidenced by completed soft-story retrofit and recent infrastructure upgrades

Risk rating

How 1538 Clay 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.

Neighborhood percentile

Out of 1125 buildings in this neighborhood, 889 are predicted to be safer.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.
