1821 Baker St

Pacific Heights, SF 94115 1023001 5 units · 2 fl · 1910

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 1821 Baker 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.

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 1910
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 property at 1821 Baker St is a two-story, five-unit multi-family residential building with an attached store component, built in 1910 and currently owned by M&mh Lp. The building has undergone several significant improvements over the past decade, with the most recent major upgrade being the installation of a new tankless water heater in March 2023 and the replacement of four Federal Pacific breaker boxes with new electrical infrastructure in November 2020, including the addition of exterior lighting. The building converted a portion of its space from office to classroom use in 2018, followed by comprehensive fire safety upgrades in 2019, including new smoke detection systems. A substantial renovation took place in 2014-2015 period, addressing kitchen and bathroom updates, furnace replacement, and various plumbing improvements, including water service installation and multiple bathroom renovations.

Historically, the building faced significant plumbing issues in late 2013, which were documented in a violation notice citing problems with inadequately supported bathtubs, leaking sewage pipes, and deteriorated vent piping, among other concerns. These violations appear to have been addressed through subsequent plumbing work completed in 2014, including the installation of new fixtures and repairs to various systems. The fire alarm system was also a focus of improvements, with a new system installed in 2012 for what appears to be a preschool facility located in the building. More recently, there have been several routine municipal service calls in the vicinity, primarily related to parking enforcement and street maintenance, with a few open service requests as of late 2024, including one regarding an overgrown tree.

Risk rating

How 1821 Baker 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
57thpercentile

Out of 963 buildings in this neighborhood, 414 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.

Number of units

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

Estimated permit spend (past 7 years)

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

Building age

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