1580 Washington St

Nob Hill, SF 94109 0186009 7 units · 3 fl · 1911

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1580 Washington 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 1911
2 or more units
7 units
Property type
Multi-Family Residential

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1911
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

1590 Washington St is a 3-story, 7-unit multi-family residential building located in Nob Hill, built in 1911 and currently managed by New Century Mngmnt Llc. The property has undergone several significant modifications and faced various compliance issues over the years, most notably regarding the mandatory Soft Story Retrofit Program. In late 2014, the building was cited for failing to submit required earthquake safety documentation, resulting in violations that included monitoring fees and an earthquake warning placard requirement. The building has a documented history of violations requiring attention in multiple areas, including security (door closer repairs), interior surface maintenance (painting), plumbing and electrical systems, fire safety (fire extinguisher recharging), and building safety (repairs to stairs and ladder modifications).

The property has undergone some improvements and modifications, including reroofing work completed in 2004 ($5,550), the legalization of basement rooms in 2002 ($1,000), and various electrical upgrades related to the same basement legalization project. More recently, between 2024 and 2023, there have been multiple reports of garbage and debris issues in the vicinity of the building, with several cases involving furniture and loose garbage on the street or sidewalk, all of which have been resolved. Historical complaints from 2000 through 2016 include various maintenance and safety concerns such as water leakage issues, routine inspections revealing multiple code violations, and a canceled permit from 1993 related to eliminating an illegal dwelling unit on the ground floor. The most recent building-related activity recorded was a routine garbage and debris complaint in October 2024, which has been resolved, though it represents the fifth such incident reported at this address in the previous 12 months.

Risk rating

How 1580 Washington 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

Lower risk — safer than most nearby

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

Typical — about average for the neighborhood

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

Higher risk — riskier than most nearby

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

Neighborhood percentile
36thpercentile

Out of 1125 buildings in this neighborhood, 720 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

Number of units

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
