California, home of the world's 4th largest economy & several of its top econ departments, has spent 50 years "planning for housing need" w/o availing itself of economic expertise.

The game is up, courtesy of the S.F. city economist. My op-ed in today's @sfchronicle ⤵️.

🧵/22 Image
What happened?

Every 8 years, CA cities must adopt a plan, called a "housing element," that shows how they'll accommodate their fair share of regionally needed housing.

/2
In June 2020, after some back-and-forth w/ regional "council of governments" (but no input from economists) @California_HCD announced the current target for the Bay Area.

/3

abag.ca.gov/sites/default/…
The regional council, @ABAGSFBayArea, then convened a committee to devise a formula for allocating the regional target among the 100+ Bay Area municipalities.

/4
The committee had no data on the market or political feasibility of putting new housing in this or that community.

One member told me off the record, "We were given two instructions: minimize GHG emissions & make rich suburbs zone for affordable multifamily housing."

/5
"When I pointed out that the two goals work at cross purposes," he continued, "the ABAG staff just shrugged."

Eventually ABAG landed on a formula.

The final allocation, adopted in Dec. of 2021, assigned ~82,000 housing units to San Francisco.

/6

abag.ca.gov/sites/default/…
That's a big number! To produce 82,000 new units over 8 years, San Francisco would need to triple the annualized rate of housing production it has realized over the last couple of decades.

It would have to build like Seattle, not like Peskinville.

/7
State law gave San Francisco a little over a year (from the release of the final allocation) to enact a plan for how to do it.

/8
S.F. planners responded w/ magical thinking about "pipeline" of entitled (but mostly stalled, b/c infeasible or needing massive infrastructure) projects to whittle the 82,000-unit target down to 36,000 units that would be accommodated w/ upzoning.

/9

The state housing agency, HCD, blessed the plan, I think b/c it committed the city to "reasonably account...using an analytical model" for sites' likelihood of development, and in part b/c it included a mid-cycle circuit breaker.

The supes passed the plan in Dec. 2022.

/10 Image
Image
State law gave city 3 years to complete the rezoning that implements core commitment of the housing element, i.e., to make up the agreed-upon 36,000 unit shortfall of "realistic capacity."

That 3-year deadline is nearly upon us (Jan 2025).

/11
.@DanielLurie's Family Zoning Plan is supposed to deliver the goods.

City planners claimed it was sufficient to meet 36k target. Their analysis was suspect & definitely not reviewed by economists...

Here's what they said to HCD,

/12drive.google.com/file/d/1ZOcNve…
HCD responded that it was “pleased to preliminarily [approve]” the rezoning, but also told SF "to continue to explore additional and multiple methods [for estimating sites’ likelihood of development] and make adjustments as appropriate.”

/13


sfgov.legistar.com/View.ashx?M=F&…
In any other city, that would have been the end of the story.

But thanks to 2004 ballot measure, SF has a city economist, who is charged w/ preparing economic-impact analyses of pending ordinances.

/14 Image
To gauge economic impact, he had to forecast development under Family Zoning Plan.

His ***highly optimistic, best case scenario*** projects that the plan will yield only ~14,000 new units over the next two decades, nowhere near the 36,000 by 2030 obligation.

Oops.

/15
If S.F. doesn't enact a compliant plan by Jan 31, it's subject to Builder's Remedy, meaning that developers may build 3x more densely than the density allowed on their site by city or state law. Height limits & anything else that precludes their project will be waived.

/16
Now take a deep breath, step back, and contemplate the craziness.

The whole theory of this planning framework is that b/c housing has positive regional spillovers (true), cities shouldn't get to decide for themselves how much to allow, but that...

/17
b/c city pols understand local preferences better than state administrators do (probably true), city pols should get to decide where the new housing goes.

Yet 5 years into planning cycle (& 3 months shy of Builder's Remedy), there's no agreed-upon model for scoring plans!

/18
The supes can't do their job w/o knowing how a plan will be scored. Instead of providing a model to score the plans, HCD just told the city to "continue to explore additional and multiple methods."

If I were a supervisor or city attorney, I'd be blowing my top.

/19
I don't mean to harsh on HCD. They're doing the job the Legislature gave them, with the staff the Legislature gave them. (No economists...)

/20
But the process needs an overhaul.

Cities need realistic, economically-informed targets.

Even more important, they need realistic, economically-informed tools with which they can quickly & easily gauge a rezoning plan's sufficiency.

/20
The state needs to provide these tools.

It makes no sense to tell city planners to devise their own models, as the planners have neither the technical knowledge nor the political incentives to come up with something reasonable.

End the guessing games. Please.

An architect who does multifamily housing throughout CA told me recently,

"The secret's not out, but San Francisco, erstwhile worst offender, has become one of the easiest places to get projects entitled & permitted in CA."

I asked what changed. He said, "The mayor."

1/5
"Just about everyone in every city dept now understands its their job to get permits issued, quickly. Mangers got their marching orders from @DanielLurie and workflows have gotten much better."

(I'm paraphrasing his remarks.)

/2
S.F. still has all sorts of lousy laws & policies that thwart housing production -- high transfer taxes, high IZ, expensive bespoke code requirements, de facto prohibitions on redevelopment of any building w/ rent-controlled units -- but mgmt apparently is much improved.

New decision from CA Court of Appeal on the fee-shifting provisions of AB 1633 has big implications for NIMBYs' incentive to challenge housing approvals under CEQA & beyond.

This one belongs in a Law of Abundance casebook.

🧵/24
law.justia.com/cases/californ…Image
Context: As part of the 1970s revolution in admin law, states & the federal gov't actively encouraged self-appointed "private attorneys general" to sue, via attorneys' fee bounties.

/2
Asymmetric fee-shifting provisions were written into scores of public laws: If a plaintiff challenging a gov't decision wins, the gov't has to pay for the plaintiff's attorney; if the plaintiff loses, they don't have to pay for the gov's attorney.

"For a typical mid-rise apartment in San José, construction costs can exceed $700k–$900k per unit."

I 💯% agree w/ @MattMahanSJ that reducing construction costs should be a top priority for 2026 -- and that this is mainly a job for the state legislature.

🧵/22
Reason #1. CA's fiscal constitution + local political incentives push local govs to extract "value" from development w/ impact fees, IZ & transfer taxes.

This drives up the cost of building enormously.

/2
The state leg should preempt most such fees, IZ, & taxes, ***and create a substitute source of local revenue.***

My preferred alternative: a state parcel tax assessed on the "net potential square feet" or "net potential units" created by upzoning pursuant to state law.

Could L.A. really land in the Builder's Remedy penalty box, just for f'ing around with a single low-income housing project which a nonprofit developer wants to build on city-owned land?

Yes.

A quick explainer🧵.
In October, @California_HCD sent L.A. a sharply worded letter, warning that the city's housing element had relied on the Venice Dell project both as a "pipeline project" and as part of the city's strategy to "affirmatively further fair housing."

/2

hcd.ca.gov/sites/default/…Image
Image
The HCD letter also flagged five "policies" and two "programs" in L.A.'s housing element that per HCD should "facilitate the project."

The city's course of action has been "inconsistent with these policies."

Cooking in San Diego: A turquoise, 23-story test of the Permit Streamlining Act's new-and-improved "deemed approved" proviso.

This could turn into a big constitutional battle.

🧵/22 Image
Image
Enacted in 1977, the PSA put time limits on CEQA and other agency reviews of development proposals.

If an agency violated the time limits, the project was to be "deemed approved" by operation of law. Wow!

It proved wholly ineffectual.

/2
As @TDuncheon & I explained, courts first decided that the Leg couldn't possibly have meant for a project to be approved before enviro review was complete.

Ergo, CEQA review must be finalized before the deemed-approval clock starts ticking.

In the topsy-turvy world of CA Density Bonus Law:

- San Francisco almost certainly must approve this 25-story project on a site zoned for 4 stories

- The city's new ordinance deregulating density in "well-resourced areas" will operate as de-facto downzoning of such sites

🧵 Image
This project's site is zoned for retail use and is currently occupied by the Marina Safeway.

The zoning classification also allows residential use at density of 1 unit per 600 sqft of lot area or density of nearest residential district, whichever is greater.

/2 Image
The nearest residential district, RM-4, allows density of 1 unit per 200 sqft of lot area.

That translates into 567 units on site.

Developer proposes to build 790 units, which requires a 39% density bonus (790/567 = 1.39).
