Santa Monica Measure GS, explained.

Santa Monica Measure GS (Ballot Measure GS, November 2022; codified in Santa Monica Muni Code) is a voter- approved transfer tax on residential property sales in the City of Santa Monica at high price tiers. It’s the most aggressive municipal transfer tax in California at the time of passage — more aggressive on a single-rate basis than even City of LA’s Measure ULA.

The 2022 ballot context

The measure passed in the same November 2022 election cycle that produced LA’s Measure ULA. The political context: both measures were funded by housing and labor groups seeking municipal funding for affordable housing and homelessness programs. Santa Monica’s concentration of wealthy oceanfront and Westside inventory produced a particularly aggressive structure given the base.

What it replaces

Measure GS is layered ON TOP OF the existing Santa Monica tiered transfer tax (Measure SM, voter-approved 2020):

• 0.3% on residential sales under $5M (pre-existing)
• 0.6% on residential sales $5M-$8M (Measure SM, 2020)
• 5.6% on residential sales $8M+ (Measure GS, 2022)

The Measure GS tier supersedes the previous structure for transactions above $8M. The lower tiers remain in place.

The basic structure

For residential property transfers in the City of Santa Monica at or above $8 million:

• Rate: 5.6% (5.6% of the entire sale price, cliff applied)
• Statutory incidence: imposed on the buyer or seller as the parties agree (typically seller per CA custom)
• Customary incidence: seller-paid by Southern California custom

Cliff vs marginal

Measure GS is a cliff, not a marginal bracket. The 5.6% applies to the entire sale price once the threshold is crossed — not just the amount above $8M.

This is the same structural choice as City of LA’s Measure ULA (both passed in the same election cycle, both use cliff structures). The implication: at the $8M threshold, the marginal tax of crossing is essentially the full 5.6% × $8M = $448K, against a previous tax of about 0.6% × $7.99M = $48K.

Combined with county + state

The total residential transfer tax stack on a Santa Monica sale at $8M+ is:

• LA County documentary transfer tax: 0.11%
• Santa Monica Measure GS: 5.6%
• (No state-level transfer tax in CA)
• Combined effective rate: 5.71% on the entire sale price

At the $8M cliff edge

• $7,990,000 sale: Measure GS = $0; Measure SM = 0.6% × $7.99M = $47,940; LA County = 0.11% × $7.99M = $8,789; Total transfer tax: $56,729
• $8,010,000 sale: Measure GS = 5.6% × $8.01M = $448,560; LA County = 0.11% × $8.01M = $8,811; Total transfer tax: $457,371
• Cliff cost: $400,642 of additional transfer tax for $20,000 of additional sale price

What this means for net seller proceeds

A seller pricing at $7.99M nets ~$7.93M after Santa Monica + LA County transfer tax. A seller pricing at $8.01M nets ~$7.55M. The seller needs to clear $8.43M (a price about $440K higher than $7.99M) just to be back to net-even. For sales clustering around the $8M mark, the cliff effectively eliminates the $8M-$8.4M zone from the negotiating range.

How sellers actually price

In the post-Measure-GS environment, Santa Monica sellers with potential market value in the $7.5M-$9M zone face a specific structural choice:

• Price below the cliff — list at $7.5M-$7.95M, accept the lower deeded price, capture the 5%+ cliff savings
• Price meaningfully above the cliff — list at $9M+, generate enough buyer interest to support a price that compensates for the substantial cliff cost
• Use seller-credit + personal property allocation — similar to NYC mansion-tax workaround, structure the deal to land just below the cliff with payments outside the deeded price (similar approach to the NYC mansion tax cliff strategy)

For sellers

The economics of pricing strategy on a Santa Monica listing near the $8M cliff:

Net seller calculation at $7.95M list:

• Sale price: $7,950,000
• Broker commission (5%): $397,500
• Measure GS: $0
• Measure SM (0.6%): $47,700
• LA County: $8,745
• Closing costs + title (~0.5%): $39,750
• Net seller: ~$7,456,000

Net seller calculation at $8.5M list:

• Sale price: $8,500,000
• Broker commission (5%): $425,000
• Measure GS (5.6%): $476,000
• LA County: $9,350
• Closing costs + title: $42,500
• Net seller: ~$7,547,000

Conclusion: On the same property, a $7.95M sale produces a net of $7.456M; an $8.5M sale produces a net of $7.547M. The seller has to clear the $8.5M price to net just $91K more than the $7.95M price.

For sellers, the practical implication: the $7.95M price level functions as a soft pricing ceiling because of the cliff. Crossing it requires substantial confidence that the buyer demand will support the higher net price.

For buyers

On the buy-side, the cliff dynamics work in your favor — sellers will price below the cliff if they can; buyers get the negotiating posture of “don’t make me cross the cliff”.

For buyers genuinely targeting properties at the $8M-$9M tier, the negotiating dynamic typically becomes:

• Offer just below the cliff with personal property allocation
• If seller refuses, walk and look for next equivalent inventory
• If you must cross the cliff, expect to pay a substantial discount from the listed price to compensate for the seller’s tax exposure

For complete context on Santa Monica residential transfer tax exposure across price tiers:

Note: Measure SM does NOT apply at the $8M+ tier — Measure GS replaces it. The Measure GS rate is therefore the entire municipal transfer tax above $8M, not in addition to Measure SM.

On a $10M Santa Monica sale, total transfer tax is $571,000. On the same dollar amount in Beverly Hills, it’s ~$11,000 (LA County only — no city transfer tax). The municipal-boundary delta is dramatic.

The Santa Monica city boundary is geographically specific. Adjacent neighborhoods in different jurisdictions face materially different transfer tax structures.

Pacific Palisades (City of LA)

Immediately north of Santa Monica. Inside City of LA limits, subject to Measure ULA (4% / 5.5% cliffs at $5.3M / $10.6M). For trophy buyers, Pacific Palisades vs Santa Monica is a meaningful municipal decision — Pacific Palisades carries ULA exposure but the 5.5% top rate kicks in at $10.6M (higher than Santa Monica’s $8M GS cliff), so transactions in the $8M-$10.5M range carry materially less tax in Pacific Palisades than in Santa Monica.

On a $9M sale:

• Santa Monica: ~$514,000 transfer tax (5.71% combined)
• Pacific Palisades (City of LA): ~$415,500 transfer tax (Measure ULA 4% + LA City + County)
• Beverly Hills: ~$10,000 (LA County only — no city transfer tax)

Brentwood (City of LA)

Northeast of Santa Monica, inside City of LA. Same Measure ULA exposure as Pacific Palisades. For trophy buyers above $5.3M, similar dynamics.

Malibu (separate city)

West of Santa Monica along the coast. Malibu is a separate city — only LA County transfer tax (0.11%) applies. No city-level transfer tax. For oceanfront-focused trophy buyers, Malibu represents a structural escape from the entire LA-area municipal transfer tax stack — at a $20M sale, ~$22K transfer tax vs ~$1.4M in Santa Monica or ~$1.1M in City of LA.

Beverly Hills (separate city)

East of Santa Monica. Separate city, no Measure ULA or Measure GS equivalent. The clearest trophy-tier escape from the LA municipal transfer tax stack. A buyer comparing Santa Monica oceanfront to Beverly Hills Flats should specifically factor the transfer tax delta — at $10M, it’s a $500K+ difference.

The Brentwood / Bel-Air comparison

For HNW buyers targeting Westside LA generally, the Brentwood / Bel-Air / Pacific Palisades trio (all inside City of LA, subject to ULA) vs the Santa Monica / Beverly Hills / Malibu trio (separate cities, varying treatment) is the decision frame at the trophy tier. Measure GS pushes Santa Monica to the harshest of the three "separate city" options.

Measure GS revenue is allocated to the City of Santa Monica’s general fund with specific priorities for:

• Affordable housing construction and preservation
• Homelessness prevention programs
• School funding for SMMUSD (Santa Monica-Malibu Unified School District)
• General city operations

Revenue performance

In its first 18 months, Measure GS collection has underperformed initial projections. The structural reason: substantial transaction volume reduction at the $8M+ tier. Sellers either price below the cliff (less revenue) or don’t list (zero revenue). The same dynamic LA City has seen with Measure ULA.

Critics argue this validates the cliff structure’s economic distortion. Supporters argue revenue is real even if below projections and the housing/homelessness funding justifies the structure.

Measure GS, like Measure ULA, faces ongoing legal challenges. The constitutional issues raised are similar:

• Uniformity challenges under CA Constitution (whether taxing some residential at much higher rates than other similarly-situated residential violates uniformity)
• Equal protection claims from impacted property owners
• Whether the measure exceeds the city’s taxation authority under CA Constitution Art. XIII §A

The challenges are working through CA courts as of mid- 2026. The tax remains in effect during litigation; if ultimately struck, refunds would be due to affected taxpayers but the short-term cash flow impact remains. Practical advice: assume the tax will continue and plan accordingly.
