147 San Carlos St

Inner Mission, SF 94110 3589029 3 units · 3 fl · 1986

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 1986
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 147 San Carlos Street in the Inner Mission, owned by Tina K. Chan, is a three-unit, three-story multi-family residential building constructed in 1986. The building experienced significant safety-related issues in April 2008, when multiple violations were documented through a routine housing inspection. These violations included necessary repairs to stairs, installation of a central alarm system, and maintenance of fire safety equipment including fire extinguishers. All of these violations were addressed and officially abated by June 6, 2008. The building underwent reroofing work in October 2008, costing $4,000, and in May 2008, repairs were made to deteriorated floor boards and joists at the rear landing of unit #2, following the issuance of a notice of violation.

Looking at more recent concerns, the property has generated numerous 311 calls between 2024 and 2025, though these primarily relate to street-level issues such as garbage, debris, and sidewalk cleaning needs rather than building-specific problems. These external maintenance issues have been consistently resolved, according to 311 records. Prior to the 2008 violations, there was a tenant complaint in 2001 regarding various appliance issues and thermal comfort problems, though these were eventually marked as resolved in July 2008. A previous routine inspection was conducted in January 2004, which was closed shortly thereafter. The building's documented history suggests that while there were serious safety concerns in 2008 that required attention, these were promptly addressed and there have been no recorded building-specific violations or complaints in the past 15+ years.

Risk rating

How 147 San Carlos 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
63rdpercentile

Out of 2380 buildings in this neighborhood, 881 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
