Redwood City's ADU Rules Just Loosened. Its November Ballot Measure Could Tighten the Return.

Redwood City's ADU Rules Just Loosened. Its November Ballot Measure Could Tighten the Return.

If you're underwriting a small multifamily deal in Redwood City right now, look at the calendar before you look at the comps. On July 7, the city council voted unanimously to send a rent control measure to the November ballot, even though several members said outright they personally oppose it. Six days later, on July 13, the same council voted to loosen the city's ADU and zoning rules to make it easier to build. Both votes are real. Both are current. And which one actually shapes your return depends on what happens on November 3, now less than three months away.

That's not a hypothetical tension. It's the specific situation facing anyone evaluating a duplex, triplex, or small apartment building on the Peninsula this fall. The city just made construction easier. Voters, not the council, will decide whether operating that inventory gets meaningfully more expensive. Here's what actually happened, in order, and how to underwrite the gap between the two.

What Loosened on July 13

The Redwood City Council approved several hundred pages of text changes to land use and city code, with the July 13 approvals meant to prepare for current and future housing needs as outlined in the city's Housing Element. The vote passed 6-1, with Council member Marcella Padilla opposed.

The motivation was explicit. Senior Planner Apollo Rojas told the council the city is facing a severe housing crisis, citing California's requirement that Redwood City approve 4,588 units by 2031, with the city aiming to add at least 7,000 units in that same period as a self-described housing leader on the Peninsula.

For anyone underwriting a multifamily-plus-ADU strategy, the specific changes matter more than the framing:

  • Multifamily sites were approved to add up to eight detached ADUs, six more than the previous cap, and the city says it will help older, previously unpermitted ADUs get legalized more easily.
  • The council extended planning entitlements from three years to as many as five, cut private open space minimums from 300 to 125 square feet per unit, and eliminated parking minimums entirely for 100 percent affordable housing, senior housing, group homes, and low-barrier navigation centers.

That eight-ADU number is the headline for investors, but it's not the only line item that changes the pro forma. Longer entitlement runway means less pressure to rush construction before a permit expires. Lower open space minimums mean a tighter lot that used to fail the numbers might now pencil.

Not every council member was comfortable with the tradeoff. Council member Diane Howard, who voted with the majority, said she has "grave concerns" about cars having "nowhere else to go" without parking requirements, calling it a possible unintended consequence of packing more housing into smaller spaces. Padilla, for her part, argued that reducing private open space could come at the expense of neighborhoods, saying the city's green spaces are finite. Those aren't abstract objections. If you're the one adding a sixth or seventh detached unit to a lot, you're the test case for whether that concern holds up on the ground.

There's one restriction buried in the same ordinance that changes an income assumption a lot of small investors make going in. The council also voted to block short-term rentals for junior ADUs, the units built within the structure of the main house, and going forward, short-term rentals citywide will be limited to one listing per day per residence, with hosts facing more hurdles proving the rental is their primary residence. If your pro forma for a house-plus-JADU purchase assumed nightly rental income from the attached unit, that assumption needs a second look before you close.

What Could Tighten on November 3

The rent control question didn't start in July. Organizers with Faith in Action Bay Area spent years gathering signatures for what's known as the Fair and Affordable Housing Ordinance, and by early June the city clerk had accepted certification of 4,751 verified signatures, comfortably clearing the roughly 4,500 needed to qualify the measure for the ballot.

That put the council in a bind under state election law. On Tuesday, July 7, the council had the option to adopt the ordinance outright and immediately, or let voters decide in November. It chose the second path, and the vote to place the measure on the Nov. 3 ballot passed unanimously. Unanimous, though, didn't mean unified. Councilmember Isabella Chu described herself as "unequivocally pro renter" but still formally opposed the ordinance, calling it seriously flawed and warning it would ultimately harm the people it was meant to help. Councilmember Diane Howard was more direct, calling the legislation "very restrictive, very far reaching, a financial burden to more than just the city" and predicting it wouldn't produce the housing supporters expect.

The financial mechanics are where this gets specific enough to actually change a deal. The ordinance would require landlords who end a tenancy for reasons unrelated to the tenant's behavior, a no-fault eviction, to pay relocation assistance equal to four times HUD's fair market rent or $12,000, whichever is greater, with additional payments required for tenants over 62 or with disabilities. That surpasses what's currently required under the city's Tenant Protection Ordinance, which calls for one month of relocation assistance for most renters and three to four months for other qualifying residents.

The funding math doesn't currently close, either. The proposed ordinance would be financed through fees of $84 to $120 per unit charged to landlords, but the city's own consultant, Economic & Planning Systems, estimated the per-unit fee needed to actually cover the program's costs would run $246 to $622 per rental unit per year. That gap projects to an annual cost to the city of $4 million to $10.1 million and would require at least seven new staff members to administer.

By the end of July, the council went a step further than just voicing personal objections. Each of the seven members agreed the ordinance carries too many unintended consequences to support, though the vote to formally oppose it wasn't unanimous. Councilmember Chris Sturken abstained, citing concerns about how a formal city stance could be perceived by renters and pointing to a decade-old campaign against a similar measure in San Mateo, where opponents had circulated racially charged mailers. Mayor Elmer Martínez Saballos, breaking with custom to speak first, urged everyone involved to "focus on the facts and argue on the policies," while Howard said she felt "a moral obligation" to tell voters where she stands rather than stay neutral.

So the same city hall that spent July making construction easier is on record opposing the measure that would make renting more expensive. The decision itself, though, sits entirely with voters this November.

A shortfall in a city-side budget doesn't stay a city-side problem for long. Fee gaps tend to get closed through future adjustments, and landlords are usually the ones asked to absorb them.

Who Actually Carries the Risk

This is the part that should reframe how you think about the deal you're underwriting, not just the deal in general.

EPS and the city's own staff report found the proposed ordinance was most likely to affect older, multifamily properties and "mom-and-pop" landlords, along with affordable housing providers, because those buildings generally need more repairs and operate on tighter margins. A separate account of the same analysis reached the same conclusion from a different angle: the ordinance's biggest impact would fall on rental stock built before 1995, older, smaller buildings that already tend to charge lower rents but need more upkeep.

That's not a coincidence of the policy. It's the mechanism. A newer building with fewer deferred repairs and a wider margin absorbs a per-unit fee increase without much strain. An older four-plex bought on thin margins for the rental income, exactly the kind of property a small investor targets for a value-add or ADU play, has less room to give.

One owner made that math concrete for the council directly. Norman Goldau, a Redwood City resident and local real estate broker who owns three separate five-unit apartment buildings, told the council the ordinance's added expenses would make his apartments unprofitable, and said it could push him out of residential rentals and into commercial real estate instead.

"I've never implemented or kept the rents on the cutting edge of what they could be. I've always been fair. I have many tenants that have lived in the apartments for 10 years or more [and] many Spanish tenants as well."

That's not a generic landlord complaint. It's the exact profile the EPS report flagged: a small, long-tenured owner whose margin is thinner than a newer building's, weighing whether the numbers still work if the fee gap gets closed through his rent roll.

How to Underwrite the Months Between Now and November

You don't get to wait for certainty before you make a decision on a deal in front of you today. But you can build the uncertainty into the model instead of ignoring it.

  1. Separate the ADU upside from the operating assumption. The eight-unit multifamily ADU allowance is real and already approved. Model it as construction-side upside. Keep it out of your rent-growth assumptions until November resolves.
  2. Stress-test the deal against the EPS cost range, not the proposed fee. If the measure passes and the funding gap gets closed through higher per-unit charges, $246 to $622 a year per unit is the range to underwrite against, not the $84 to $120 currently proposed.
  3. Weight older buildings more conservatively. If the property you're evaluating fits the profile EPS flagged, older stock, thin margins, deferred maintenance, treat the potential rent control exposure as a bigger swing factor in your return than you would on newer construction.
  4. Drop short-term rental income from any JADU underwriting. The nightly-rental assumption on an attached unit no longer holds under the new rule, regardless of what the property's current listing history shows.
  5. Use the longer entitlement window to your advantage. A five-year runway instead of three means you can permit now and delay vertical construction until after November without losing your approval, if the additional time helps you underwrite with more certainty.

None of this tells you whether to buy. It tells you which numbers in your model are settled and which ones are still in motion until voters weigh in.

FAQ

Does the eight-ADU allowance apply to single-family lots, or only multifamily? The July change was scoped specifically to multifamily sites. Redwood City's standard rule for most single-family homes, in line with state law, still allows one detached ADU plus one Junior ADU per lot, and that baseline wasn't part of the July 13 changes.

If I already rent a junior ADU short-term, does the new rule apply to me right away? The coverage of the ordinance doesn't specify a grandfather clause for existing short-term JADU rentals. If you currently have one, the safest move is to contact Redwood City's planning division directly and get the transition timeline in writing before you rely on that income again.

Would the rent control measure apply to a small duplex, or only larger buildings? The reporting describes the ordinance as covering "a broader swath of housing units" than the city's existing Tenant Protection Ordinance, but a specific unit-count threshold hasn't been detailed in coverage so far. Treat this as pending. If you're underwriting a small property now, don't assume an exemption until the final ballot language is public.

Redwood City's council spent July trying to make it easier to build, and it's on record opposing the ballot measure that could make operating harder. But the council doesn't get the final vote. Voters do, on November 3, and a citizen-led campaign that already cleared its signature threshold isn't going away quietly. If you're the one financing a small multifamily deal in between, you're the one who needs to know which numbers are settled and which are still up for a vote.
