Inner Sunset, SF 94122 1842028 3 units · 2 fl · 1982

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.

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 1982
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 property at 1470-1472 12th Avenue in San Francisco's Inner Sunset neighborhood is a two-story multi-family residential building constructed in 1982, currently owned by the Ho Family Trust. The building has undergone significant changes and improvements over recent years, most notably in 2019-2020 when the basement was converted into a studio unit, increasing the total number of units from two to three. This conversion triggered a series of safety upgrades, including the installation of a new fire sprinkler system throughout the ground floor and basement, as well as a manual fire alarm system with sprinkler monitoring capabilities, all completed in 2020 at a combined cost of over $39,000. The building's safety infrastructure was further enhanced with comprehensive electrical and plumbing work in 2020-2021, including the relocation of water heaters and various system upgrades.

The property has a history of various maintenance and safety issues, particularly evident from 2015 to 2018, including water leakage problems, electrical issues, and concerns about unauthorized dwelling units. Multiple building violations were recorded in 2015 related to fire safety and sanitation, including mold/mildew presence, damaged ceilings, and egress obstructions. A significant safety incident occurred in 2017 involving gas leaks connected to improperly installed water heaters, prompting emergency response and subsequent corrective actions. Notably, there is an active building violation from 2018 regarding unauthorized dwelling units that appears to have been addressed through subsequent legalization efforts. The building has also experienced various infrastructure issues over the years, including plumbing problems and historical concerns about water damage and electrical systems, as documented in complaints dating back to the 1990s. Recent 311 calls primarily relate to parking issues in the vicinity of the building, with no recent internal building complaints recorded.

Risk rating

How 1470-1472 12Th 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
18thpercentile

Out of 1493 buildings in this neighborhood, 1224 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
