433-445 Lombard St

Telegraph Hill, SF 94133 0077038 6 units · 3 fl · 1909

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 433-445 Lombard 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 1909
2 or more units

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 1909
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 three-story, six-unit multi-family residential building at 433-445 Lombard Street, constructed in 1909 and currently owned by 433 Lombard LLC, has undergone several significant changes and faced various maintenance challenges over the years. Most recently, in February 2022, a substantial renovation project was filed, focusing on improvements to the exterior facade, waterproofing of the basement, and roof work including the replacement of an exterior roof deck with non-combustible materials, though this permit status remains as "Filed" rather than complete. A notable event occurred in 2017 with the attempted legalization of an unauthorized dwelling unit installation, though the current status of this application is listed as "Under Review" in planning records.

The building has experienced several infrastructure issues, including a recent sewage backup incident reported in November 2024 and multiple sewer-related repairs, including a foundation-to-city connection replacement in 2010. Previous violations and complaints from 2003-2006 revealed various maintenance concerns, including problems with handrails, stairs, floor coverings, and fire safety equipment, though all these violations were officially abated by August 2003. Historical complaints indicate past issues with inadequate heating systems and mold problems in 1999. The building's external environment has been subject to periodic urban challenges as evidenced by multiple 311 calls regarding street and sidewalk maintenance, with the most recent such issues appearing in 2022-2024.

Risk rating

How 433-445 Lombard 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
27thpercentile

Out of 684 buildings in this neighborhood, 499 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

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
