Environmental Constraints: The Scarcity Premium

Revision note, 27 September 2026#

This article was corrected on 27 September 2026. A check of its figures and attributions against the cited sources found errors, which have been corrected in the text. The full list, with what the article said and what it says now, is in the corrections section at the end.

The paradox: regulation as a floor, not a ceiling#

A building moratorium looks, on first read, like value destruction. It stops new supply, freezes permitting, and in the short run it depresses transaction volume as buyers and developers wait for clarity. Underwriting models built on unconstrained markets treat this as a pure negative: less activity, less liquidity, more uncertainty. That read is not wrong about the transition period. It is wrong about the equilibrium the transition leads to. The mistake is common because most underwriting frameworks were built for markets where supply eventually answers demand, where a moratorium is a pause, not a permanent feature of the topology.

The record across several resort jurisdictions shows a second-order effect that dominates the first. Once a constraint is tested (by a referendum, by a court, by two or three decades of enforcement), it stops being a source of uncertainty and starts being a source of information. It tells the principal exactly how much competing supply can ever exist. Switzerland's second-home cap, Pitkin County's growth ceiling around Aspen, and the Lake Tahoe Basin's building moratoria, upheld by the U.S. Supreme Court, are three instruments that reached that second state. Each is examined below, alongside a case where the same class of regulation destroyed value instead of protecting it, the honest counterweight to the thesis, and the reason this document does not read as promotional material for regulatory risk.

Switzerland: the 20% threshold#

Switzerland's Second Homes Act caps new second-home construction at 20% of a municipality's residential stock, and the cap is binding, not aspirational. Swiss voters approved the Second Home Initiative on 11 March 2012 with 50.6% in favour and a majority of cantons (12 cantons and 3 half-cantons, according to Hilber and Schöni); the federal law took effect on 1 January 2016 after a provisional ordinance had already applied the cap from January 2013. Once a commune's share of second homes crosses 20%, the construction of new unrestricted second homes stops, subject to narrow statutory exceptions such as tourist-managed units. Verbier, Zermatt, Crans-Montana, Gstaad, St. Moritz and Saas-Fee crossed that threshold years ago. In each of those resorts, new supply of unrestricted second homes is now tightly limited by statute, though not frozen: since 1 October 2024 a revision allows buildings that predate the 2012 vote to be demolished, rebuilt and enlarged by up to 30%, with additional units (EspaceSuisse; Swiss Federal Council, 13 September 2024).

The consequence is a closed-end asset class inside an open-ended demand pool. A peer-reviewed study of the ban, Hilber and Schöni in the Journal of Urban Economics (2020), estimates that it raised the price growth of second homes in affected municipalities by 26% and lowered the price growth of primary homes by 15%; these are average effects on price growth, not a premium for any single property. Knight Frank's Ski Property Report recorded Verbier at roughly €21,900 per square metre in 2021 and Zermatt at roughly €20,700 per square metre in 2020, among the highest prime-ski values it tracks in Europe, both markets operating under the cap. The statute did not create the demand for Alpine second homes. It fixed the supply that demand competes for, and a second, parallel statute, Lex Koller, restricts who is even eligible to compete for it, a point returned to later in this document.

Aspen: a quota on growth#

Pitkin County's 1979 Land Use Code capped growth in the Aspen area at 50 units a year, according to a 2023 history of Aspen's housing legislation, after the county's housing stock had grown by 184 units a year between 1960 and 1970. The instrument today is the Growth Management Quota System of the Pitkin County Land Use Code, which sets annual allotment ceilings in square feet of floor area rather than in units, and the Aspen area has seen further limits since: the city imposed a further land-use moratorium from April 2006 through the summer of 2007, and, from 8 December 2021, an emergency moratorium on certain residential building permits that ran to 8 August 2022, alongside a moratorium on new short-term rental permits that ran to 30 September 2022 (City of Aspen), adopted to ease the city's affordable-housing crunch (Colorado Sun). Each moratorium tightened the market's understanding that Aspen's growth ceiling is a standing feature of the jurisdiction, not a one-time political event that fades with the next election cycle.

Under a quota system, a building permit itself becomes a scarce, allocated resource rather than an administrative formality. New construction competes for a fixed annual allotment; it does not simply respond to demand the way it would in an unconstrained market. That structure raises the replacement cost of everything already built, because a buyer cannot simply commission a substitute. They must wait for, or acquire, an allotment that a fixed number of other applicants are also competing for. Four decades of continuous enforcement (through multiple recessions, ski-industry cycles and a pandemic-era demand surge) is the evidence that this is a durable constraint rather than a temporary dip in permitting activity, and each subsequent moratorium has functioned as a fresh test of the same commitment.

Lake Tahoe: the constraint that survived the Supreme Court#

The Tahoe Regional Planning Agency imposed two building moratoria on the Lake Tahoe Basin, in 1981 and again in 1983, together suspending construction on sensitive lands for 32 months. The purpose was to give TRPA time to write a comprehensive regional plan capable of protecting the lake's renowned water clarity, a public good the agency judged was being eroded by uncontrolled shoreline and hillside development across the California and Nevada sides of the basin. For property owners caught inside the freeze, the moratoria looked exactly like an uncompensated seizure of the right to build, and a group of them organised as the Tahoe-Sierra Preservation Council to say so in court.

That claim was tested to the highest court in the United States, and the constraint held. In Tahoe-Sierra Preservation Council, Inc. v. Tahoe Regional Planning Agency, 535 U.S. 302 (2002), the Supreme Court ruled 6–3 that a temporary moratorium on development, imposed while a land-use authority prepares a comprehensive plan, is not a categorical taking requiring compensation under the Fifth Amendment. The Court treated the moratorium as a regulation of use rather than an acquisition of property, and it declined to adopt a rule that would have made every planning-stage building freeze automatically compensable, insisting instead on a fact-specific inquiry. For the allocator, the case matters less for its facts than for its precedent: a court of last resort has already confirmed that this class of environmental constraint is legally durable, which is a different and stronger fact than a policy simply being popular with the electorate that enacted it.

Bali: a height limit that predates the modern resort economy#

Bali has restricted building height to roughly 15 metres (the height of a mature coconut tree) since 1971, and the rule has outlasted five decades of tourism growth it never anticipated. The limit was reaffirmed in 2023 through Regional Regulation (Perda) of the Province of Bali Number 2 of 2023 on Spatial Planning, Article 100 of which sets the 15-metre ceiling with narrow exceptions for places of worship, telecommunication towers and disaster-monitoring infrastructure. Unlike Switzerland's threshold-based cap or Aspen's numeric quota, Bali's constraint is a form limit: it does not cap how many buildings can exist, only how tall any of them can be. The effect on the resort skyline is the same as a supply cap in practice. It forecloses the high-density, high-rise product type entirely, protecting the low-rise villa and boutique-resort typology that defines the island's prime tier, and it means land itself, rather than air rights, carries most of the value in any given plot.

The honest caveat belongs here, not in a separate section: this constraint is under active political pressure to loosen. The Bali provincial parliament's special committee on spatial planning, assets and licensing (Pansus TRAP) has proposed value-based special height zoning that would allow buildings up to 45 metres in selected coastal and tourist zones, rather than removing the height cap island-wide. As of May 2026 the proposal remained under discussion, not enacted (WhatsNew Indonesia, 7 May 2026), a directional signal of where regulatory risk sits, not a fact to underwrite. A principal holding land in a zone that regulators might one day designate for taller building is holding an option on relaxation, not a guarantee of it, and the two should not be priced the same way.

Nantucket: scarcity without a single statute#

Nantucket protects value through geography and layered local zoning rather than through one headline law, and the result is a softer, more diffuse version of the same mechanism. The island covers roughly 48 square miles, about half the roughly 100 square miles of Martha's Vineyard (FatFire), and the Town of Nantucket reports that more than half of its land is preserved for conservation. Historic-district review adds a second layer, constraining not just whether a lot can be built on but what can be built there, down to roofline and cladding material. In 2015, Nantucket voters approved zoning bylaws permitting higher density (up to nine single-family units per acre and 23 apartment units per acre) on two specific parcels totalling 32 acres, with 25% of units required to qualify as affordable housing. The bylaws were notable precisely because they were the exception: a deliberate, narrowly targeted release valve inside an otherwise tight system, not a general loosening of the island's development limits.

This case is included as a directional data point, not a measured one, and the distinction matters for how much weight to place on it. Unlike Lex Weber's 20% threshold, Pitkin County's allotment quota, or Bali's 15-metre limit, there is no single verifiable number that captures Nantucket's constraint. The evidence is qualitative (finite land, layered zoning, conservation set-asides) and should be underwritten with correspondingly lower confidence than the statutory examples above it. A principal building a scarcity thesis around Nantucket should treat it as corroborating evidence for the broader pattern, not as a load-bearing case on its own.

Why a cap becomes a floor#

Resort demand is inelastic to place in a way that ordinary housing demand is not. A buyer of a primary residence can substitute one metropolitan submarket for another with only a lifestyle adjustment. A buyer of a chalet in a Lex Weber-capped commune, or a permitted lot inside Aspen's growth quota, is not buying a substitutable unit of shelter. They are buying access to a specific, legally bounded supply of a specific place, with a specific lake, mountain or coastline attached to it that cannot be replicated elsewhere. When that supply is fixed by statute rather than by the ordinary construction cycle, the market cannot respond to a demand surge the way an unconstrained market would: by building more. The adjustment happens entirely on price, because the volume side of the equation has been legislated shut.

Knight Frank's global tracking gives a broker-reported, directional read on the scale of that effect. In its Prime International Residential Index published with The Wealth Report 2025 (March 2025), Knight Frank recorded prime resort markets rising nearly 30% since the pandemic, against 25% for ski markets and 19% for cities. The figure is an index across many markets with varying degrees of supply constraint, not a controlled study isolating regulation as the sole cause. Demand factors, currency effects and post-pandemic relocation all contribute, and the ranking could plausibly reverse in a different demand cycle. It should be read as consistent with the thesis, not as proof of it, and the underwriting weight placed on it should be sized accordingly.

The honest exception: when regulation destroys value instead#

Spain's Ley de Costas is the same category of instrument as every case above, and in one prominent case it produced the opposite outcome. The law sets a 100-metre protection zone inland from the shoreline in which new construction of this kind is barred. The Algarrobico hotel, a 411-room, 21-floor concrete structure occupying roughly 21,000 square metres inside the Cabo de Gata-Níjar Natural Park in Almería, was built from 2003 under a municipal licence, 14 metres from the sea and inside the zone the statute protects. A court order halted construction in 2006, and the building has stood as an unfinished, abandoned structure for two decades, a landmark eyesore inside one of Spain's most protected coastal parks. In February 2025 the Spanish government approved a public-utility declaration covering the part of the property inside the 100-metre coastal protection zone, the step needed to expropriate it (La Moncloa); on 7 July 2026 the Carboneras town council voted to annul the 2003 licence, and in September 2026 the Junta de Andalucía ordered demolition of the hotel and restoration of the land (idealista, 14 September 2026).

The lesson is the honest counterweight to the entire thesis: an environmental constraint protects value only for the party that complies with it before capital is committed. El Algarrobico's developer held a municipal licence, yet the Supreme Court ruled in 2016 that the hotel stood on non-developable land, and the licence was annulled in 2026 (Infobae; idealista). Two decades of litigation are the realised cost: capital locked into a structure that has stood closed and unused and is now heading toward demolition rather than sale. The same regulatory machine that turns a respected constraint into a scarcity premium for a compliant holder can leave capital stranded when a project breaches a higher-order constraint, even one that a local permit appeared to allow. Environmental regulation in resort markets is not uniformly protective. It is protective conditionally, and the condition is compliance from the first permit onward.

The honest limit: constraints move too#

None of the instruments examined here should be underwritten as permanent, and each carries a live political question mark. Switzerland's Lex Weber has already been loosened once: a revision adopted by Parliament in March 2024 and in force since 1 October 2024 lets pre-2012 buildings in capped communes be demolished, rebuilt and enlarged by up to 30%, with additional units, a change its backers justified partly by housing shortages in tourist communes (EspaceSuisse; Swiss Federal Council, 13 September 2024). Bali's 45-metre special-zone proposal points the same direction. Aspen's moratoria have historically been temporary by design, meaning the underlying GMQS framework itself remains subject to revision by future county commissions responding to different political pressures than the ones that created it. The Tahoe-Sierra ruling establishes that a temporary moratorium is not automatically a taking. It does not establish that any given constraint will remain in force indefinitely, or that a regulator cannot choose to relax it once the political coalition that enacted it has moved on.

A second honest limit concerns liquidity, not just price. A market frozen against new supply is often also constrained on the buyer side: Switzerland's parallel foreign-ownership law, Lex Koller, restricts who may purchase property in many of the same communes capped by Lex Weber, narrowing the pool of eligible buyers precisely where the scarcity premium is highest. A constraint that supports price can simultaneously reduce the speed and certainty of an exit, since a smaller buyer pool means a longer marketing period and more sensitivity to a single counterparty's financing timeline. The principal underwriting a scarcity thesis should price that trade-off explicitly, not treat price support and liquidity as independent variables that move together.

What the allocator underwrites#

The diligence question is never whether a market has an environmental constraint (most resort markets now do). It is whether the specific constraint is statutory rather than administrative discretion, whether it has survived a full political or legal cycle rather than existing only as a recent announcement, and whether the specific asset being evaluated was built in compliance with it from the first permit. A threshold-based cap like Lex Weber is worth checking at the level of the individual commune: whether the 20% line has already been crossed there, not simply that Switzerland has such a law nationally. A quota system like Aspen's GMQS is worth checking for its enforcement record across cycles, not just its statutory existence on paper. A court-tested moratorium like Tahoe's carries more weight than an untested one, because the test is what converts a policy into a precedent, and a precedent is worth more to an underwriter than an intention.

The paradox holds only for the constraint that has actually been verified, not for the constraint that is merely asserted. A statute on the books, a crossed threshold, and a compliance record are a different asset than a rumour of future scarcity or a proposal not yet enacted. Environmental limits protect capital that respects them and can destroy capital that does not; the diligence is what tells the principal which side of that line a given asset sits on, and no amount of scenic value substitutes for that verification.

Corrections, 27 September 2026#

What the article said and what it says now. The published version said that second homes in Lex Weber communes trade at a reported 24-47% premium over primary residences, citing Oaks.ch; that page contains no such figure, and the article now cites Hilber and Schöni (Journal of Urban Economics, 2020), who estimate that the ban raised second-home price growth by 26% and lowered primary-home price growth by 15%. The published version described the Lex Weber revision as debated but not adopted and the stock of second homes as fixed by statute; the revision was approved by Parliament in March 2024 and has been in force since 1 October 2024, relaxing the rules for pre-2012 buildings (Swiss Federal Council; EspaceSuisse), and the law has always allowed exceptions such as tourist-managed units (UNINOT). The published version attributed the 50-units-a-year Aspen cap and the 1960s pace of 184 units a year to Pitkin County's GMQS Chapter 6 and presented the cap as current; that document sets annual ceilings in square feet, so the figures are now attributed to a 2023 Emory University history as the 1979 code, and an unsourced reference to a 1993 formalisation has been removed. The 2021-22 Aspen moratorium was described as aimed at demolition and rebuilding; it covered residential permits and new vacation-rental permits from 8 December 2021 to 8 August 2022 (City of Aspen). The Knight Frank figures of 30%, 25% and 19% were attributed to The Wealth Report 2026; they come from the Prime International Residential Index takeaways of March 2025 (The Wealth Report 2025). The Bali 45-metre proposal is now dated to May 2026 (WhatsNew Indonesia), and Article 100 of Perda No. 2/2023 is now sourced to the Bali provincial spatial-planning portal. On El Algarrobico, the published version said the developer built in direct violation of the statute, betting on non-enforcement; the developer held a 2003 municipal licence that the Supreme Court found did not make the land developable (2016) and that the Carboneras council annulled on 7 July 2026, after which the Junta de Andalucía ordered demolition of the whole hotel in September 2026 (Infobae; idealista), and the reference to a February 2006 halt now reads 2006. The meta description and a pull quote that described Ley de Costas and Aspen's quota as the same statute have also been corrected.

A further review on the same day refined some of the corrections above and fixed further points. The article said that the 2012 Second Home Initiative was approved in 12½ cantons; it won a majority of cantons with 12 cantons and 3 half-cantons, according to Hilber and Schöni (Journal of Urban Economics, 2020). The article said that Aspen's 2021-22 moratorium covered residential permits and new vacation-rental permits until 8 August 2022 and was adopted as the city described its housing market as in crisis; the moratorium on certain residential building permits ran from 8 December 2021 to 8 August 2022, the moratorium on new short-term rental permits ran to 30 September 2022 (City of Aspen), and the emergency ordinance was adopted to ease the city's affordable-housing crunch (Colorado Sun). The article put Nantucket at roughly 45 square miles against 96 for Martha's Vineyard and said that land suitable for new development had largely been absorbed into conservation easements, municipal use or private lots, which its sources did not support; the article now gives roughly 48 and 100 square miles (FatFire) and states that more than half of Nantucket's land is preserved for conservation (Town of Nantucket). The article said that the February 2025 declaration concerned the part of the El Algarrobico site on state coastal land and that the expropriation valuation remained disputed, citing idealista; the declaration covers the part of the property inside the 100-metre coastal protection zone (La Moncloa), and the reference to a valuation dispute, which idealista does not report, has been removed. The Knight Frank stat now reads nearly 30%, as the source states.
