1831 Grant Ave

Telegraph Hill, SF 94133 0062005 8 units · 3 fl · 1965

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 1831 Grant Ave 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.

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.

Just-cause eviction

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

1831 Grant Avenue is a three-story multi-family residential building constructed in 1965, comprising 8 units and currently owned by Stephen F. Patterson. The building has undergone significant safety and modernization improvements in recent years, with particular attention to fire safety systems. In 2023-2024, major upgrades included the installation of a new fire sprinkler system in unit 103, a comprehensive fire alarm system upgrade with wireless sounders in sleeping rooms, and a like-for-like system replacement of both the fire alarm and fire sprinkler systems. The building completed its mandatory seismic retrofit (Tier 3) requirements in 2014.

The property has experienced substantial recent renovations, particularly in unit 103, including emergency water damage repairs (2020), kitchen and bath remodels (2020), and a significant 360-square-foot addition (2021). A notable fire incident occurred in August 2018, affecting unit 301 and resulting in approximately $30,000 in repairs, though there have been no subsequent fire-related incidents. The building's infrastructure has been steadily upgraded, with improvements to electrical systems, including new sub-panels and rewiring work in multiple units between 2018 and 2023, and plumbing enhancements including bathroom remodels and fixture replacements across several units.

Risk rating

How 1831 Grant Ave'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
15thpercentile

Out of 684 buildings in this neighborhood, 581 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

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 permits (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.
