The Outer Richmond's New Zoning Map Rewards the Block, Not the Rent Roll

If you own a two-unit building in the Outer Richmond, or you're underwriting one, here's the question that actually decides whether San Francisco's rezoning touched your property: does the lot front Geary, Clement, or Balboa? Not whether the tenants are covered by rent control. Not whether the building is old enough to have qualified for the exemption that dominated the public fight over this plan in 2025. The corridor question.

That's not how the debate got covered. For most of last year, the loudest argument over San Francisco's Family Zoning Plan was about protecting rent-controlled housing from demolition. The plan took effect January 12, 2026, and the political win that got the most attention was Supervisor Myrna Melgar's amendment shielding buildings with three or more rent-controlled units from the new upzoning rules. Mayor Lurie signed off on it. It sounded like the fight that mattered. For the Outer Richmond's small multifamily stock, it mostly wasn't.

What the Exemption Actually Covers

Melgar's amendment applies to buildings with three or more units that are subject to the city's rent ordinance, which in practice means housing built before 1979. According to an analysis of the plan, that single threshold shift exempted roughly 84,000 rental units across 11,700 buildings citywide from the rezoning entirely. It was a deliberate line: San Francisco's own housing capacity math had already assumed larger pre-1979 buildings wouldn't be redeveloped, so setting the exemption at three units rather than four locked that assumption in without blowing up the city's state-mandated housing numbers.

Two-unit buildings didn't get that protection. They stayed technically eligible for upzoning, and citywide that's about 20,700 properties. If you own a duplex in the Outer Richmond built before 1979, this is the group your building falls into on paper.

The Group Left Exposed Turned Out Smaller Than It Sounds

Here's where the mechanism actually works differently than the exemption debate implied. Of those 20,700 two-unit buildings left outside the rent-control shield, only about 16% are getting any height limit increase under the plan. The other 84% aren't on the commercial and transit corridors where the bulk of the upzoning was targeted, so the exemption they didn't get doesn't translate into a height bump they can build to.

That distinction matters more in the Outer Richmond than almost anywhere else in the city. The neighborhood has exactly three east-west corridors that carry commercial zoning and bus lines: Geary, Clement, and Balboa. Everything else is numbered avenues, and the numbered avenues are where most of the neighborhood's older two-flats and small apartment buildings actually sit. A duplex two lots off Geary and a duplex on Geary itself both lost the rent-control exemption fight in the same way. Only one of them picked up development value from winning it.

Where the Height Actually Landed

The city's own zoning map draws a clear line between corridor and interior parcels.

The plan's own language is explicit about the interior blocks: form-based rules stay in place off the corridors, and what changed is density, not height. A four-story lot can now hold more units than it could before, but it's still a four-story lot unless it's a corner or a large enough parcel to qualify as an "opportunity site."

That's a meaningfully different kind of upside than what a Geary-facing parcel got. Removing a density cap on an existing four-story envelope raises the unit count a small building could theoretically support. An 85-foot allowance on a commercial corridor changes what the land itself is worth to a developer, because it changes the building that could replace what's there now.

What an Upzoned Parcel Looks Like Right Now

By August 2026, seven months after the plan took effect, the San Francisco Chronicle reported that citywide activity had arrived "with more of a whimper than a bang," with few new applications filed despite the expanded capacity. The one project getting held up as a test case, an eight-story approval at 230 Anza Street in the Inner Richmond, was called a "poster child" by the Planning Commission's president specifically because so little else had moved yet.

The Outer Richmond has its own live example, and it's a useful one because it shows exactly what a corridor-qualified parcel looks like in practice. In May 2026, Align Real Estate and Safeway filed a formal permit application to redevelop the Safeway store at 850 La Playa Street, at the western edge of the neighborhood near Ocean Beach, into an 85-foot building that combines housing with a rebuilt grocery store. The site qualifies for that height because it's a large commercial parcel on a corridor, not because of anything about the units above it. It's the kind of lot the rezoning was built around: big, already commercial, sitting where the map drew its highest number.

That's also roughly the profile of parcel the Outer Richmond has been short on. Reporting on the neighborhood's building activity found that in 2024, before any of this took effect, the Outer Richmond added zero new homes through new construction. The corridor upzoning targets exactly the kind of underbuilt commercial site that produced that number, which is also why it does very little for the residential avenues surrounding it.

Checking Your Own Block Before You Price Anything

None of this means the rent-control exemption fight was pointless. It kept 11,700 buildings and 84,000 units off the demolition table, and for owners of three-plus unit rent-controlled buildings, that's the relevant outcome. But if you're pricing a two-unit building in the Outer Richmond, or comparing what a similar property would be worth in a neighborhood with a different corridor map, the exemption status isn't the number to check first. The address is.

A duplex facing Geary, Clement, or Balboa carries a different kind of long-term land value than an identical duplex a block over, and that gap didn't exist before January 2026 in the same way. A corner lot or a parcel over 8,000 square feet on an interior street picked up real upside too, independent of corridor frontage, because of the opportunity-site allowance. Everything else on the numbered avenues kept its existing four-story ceiling and got a modest density loosening that mostly matters if you're already planning to add units within that envelope.

For anyone underwriting a purchase or thinking about the timing of a sale, that's a lot-specific question, not a neighborhood-wide one. The zoning map answers it more precisely than the headlines about the rent-control fight ever did.

A couple of questions worth asking directly

What size building does the rent-control exemption actually cover? Buildings with three or more units subject to San Francisco's rent ordinance, which applies to housing built before 1979. Two-unit buildings, even pre-1979 ones, remain technically eligible for upzoning under the plan.

If my two-unit building isn't on Geary, Clement, or Balboa, can it still pick up extra height? Only if it's a corner lot or sits on a parcel larger than 8,000 square feet, both of which qualify for up to six stories regardless of corridor frontage. Otherwise, interior parcels keep their existing height limit even though the density cap on units was lifted.

If you own or are evaluating a small multifamily building in the Outer Richmond and want to know what your specific lot actually qualifies for under the new map, that's not something a neighborhood average can answer.
