Rent & eviction protection

Is 727-731 Chestnut 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.

Built 1912

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.

Built 1912
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 Chestnut Street property at 727-731 is a three-story, 10-unit multi-family residential building located in Russian Hill, built in 1912 and currently owned by Leslie Lum. The building has undergone several significant renovations in recent years, most notably in 2022 when units 727 and 731A received comprehensive remodeling including kitchen and bathroom updates, window replacements, and electrical system upgrades, costing approximately $60,000. These renovations followed a series of complaints in 2022 regarding construction work being performed without proper permits, excessive noise, and temporary hot water shutdowns. Prior to this, Unit 729B underwent window installation in 2010, which was properly permitted and included the installation of seven vinyl windows with modern energy efficiency features.

The building has experienced various maintenance and safety concerns over the years, with several violations documented in 2010 regarding lead paint hazards, interior surface conditions, and building sanitation issues, though these were abated by December 2010. A cluster of housing code violations was recorded in 2005, including issues with fire extinguishers, wood stairs, and smoke detection systems, all of which were also resolved. More recent complaints in 2023 related to fire safety equipment were found to have "No Merit" or were "Condition Corrected." The property has maintained an active response to building maintenance needs, as evidenced by multiple completed permits for plumbing, electrical, and general repairs throughout the years. Recent 311 calls from 2023-2024 primarily relate to street cleaning, sidewalk maintenance, and external issues rather than building-specific concerns, suggesting improved property upkeep in recent years.

Risk rating

How 727-731 Chestnut 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 1133 buildings in this neighborhood, 1088 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
