Rent & eviction protection

Is 3552-3558 23Rd 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 1900
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 3552-3558 23rd Street in Noe Valley is a two-story mixed-use building constructed in 1900, containing 8 residential units plus commercial space, currently owned by Trust A. The building has undergone numerous renovations and improvements over the years, with significant recent activity in 2022-2023 including a kitchen/bath remodel (cost: $40,000), plumbing upgrades including bathroom and kitchen renovations, and ADA compliance work. Several historical commercial improvements were made in 2014-2016, including electrical service upgrades, ADA door installations, and work related to the ground-floor retail spaces which have housed a grocery store, hair salon, and nail salon. The property experienced multiple building violations in 2007 related to unauthorized construction work and electrical issues, though these were subsequently resolved. More recently, there is an active complaint filed in October 2022 regarding unpermitted construction work and noise disruptions during renovation work, which remains unresolved as of October 2023.

The building's utilities infrastructure has received significant attention, with multiple water heater installations (most recently in 2023), plumbing upgrades including galvanized pipe replacement, and electrical system improvements including a 400-amp service upgrade in 2014. The property has maintained compliance with major safety requirements, though there was one fire alarm system complaint in 2013 that was determined to have no merit. Recent maintenance issues have included recurring reports of garbage and debris in the vicinity (most recently in 2024), and two instances of non-offensive graffiti on the residential portion of the building in 2023 that were not responded to by the Department of Public Works. While the building has undergone substantial renovations and improvements, the presence of recent active complaints and documented history of unpermitted work suggests ongoing compliance monitoring may be necessary.

Risk rating

How 3552-3558 23Rd 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
4thpercentile

Out of 1879 buildings in this neighborhood, 1804 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.

Building size

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

Neighborhood (ZIP code)

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