The Certified Spaces Standard · V1.0 · 2026
The only hospitality standard that measures the environment at the guest level, with calibrated instruments, against published thresholds.
“Eight pathways measured. One community delivered.”
Founded by Human Garage · Verified by the Building Biology Institutes worldwide
Measured, not reviewed
A guest takes roughly 20,000 breaths per stay. Every breath is a dose. Star ratings and spa menus don’t change what’s in the air, the water, the bed, or the walls — so we don’t rate the brochure. We bring instruments, we take readings, and we certify only what an audit can prove against a published threshold.
The foundation
The healthiest indoor environment is the one that most closely reproduces unspoiled nature — clean air, clean water, natural light and materials.
Where a substance or exposure is plausibly harmful, reduce it — without waiting for absolute proof. Absence of certainty is not permission.
You spend a third of your stay asleep and defenceless. The bed is where exposure matters most — so it is where we measure hardest.

The eight pathways
Six pathways measure toxic load. Two measure the restorative environment. Each is scored against published thresholds, with calibrated instruments, on site.
PM2.5, VOCs, CO₂, formaldehyde, fragrance load.
WHO · EPA
Heavy metals, chlorine, micro-plastics, fluoride, source integrity.
EPA · EU DWD
Spectrum, intensity, blackout, daylight, light pollution.
CIRCADIAN
RF, dirty electricity, a wired option, body voltage, smart-device load.
SBM-2015
Bedding, linens, paints, finishes, furniture, cleaning chemistry.
OEKO-TEX
Cooking oils, cookware, sourcing, sweeteners, prep water.
SOURCE-VERIFIED
Nature access, greenery, views, restorative spatial design.
RESTORATIVE
Acoustic environment, ambient dB, noise floor, sensory load.
WHO NIGHT · dB
Eight pathways. One restorative environment.
Our specialties
Most “wellness” never touches EMF. We measure the field you actually sleep inside — RF, dirty electricity, and body voltage — at the pillow, not at the panel. It is the single biggest gap in the industry, and our clearest differentiator.
Measured in the bed · SBM-2015“Unscented” is a marketing word, not a measurement. We test for added fragrance and masking agents — because a scented lobby is an undisclosed chemical exposure.
Fragrance load · testedWe don’t certify a building in the abstract. We certify the environment around the bed — the place your body is most exposed and least defended.
The bed · the critical zoneThe three states
One is an on-ramp. One is the standard. One is earned, kept, and never sold.
An on-ramp for properties that have begun the work — a declared intent to certify, with a remote pre-screen. No seal. Visibly subordinate.
Expires in 12 monthsAll eight pathways verified on site, with calibrated instruments, against published thresholds. The seal deep-links to the property’s public registry record.
Eight pathways · verified on siteEarned at top thresholds across every pathway. Kept only by annual on-site re-verification. A hallmark, not a badge — engraved, never a sticker.
Cannot be purchasedVerified amenities
Recovery amenities are verified for presence, correct installation, and the environment of the amenity itself — the air of the sauna, the water of the cold plunge. They are never scored on a scale, and we make no medical claims. We simply confirm what is really there.
The audit process
You apply. We scope the property and confirm fit.
Documents, materials, and water source reviewed before anyone travels.
A trained assessor measures every pathway — in the bed, at the tap, in the air.
Readings scored against published thresholds. Findings written up in full.
State awarded, seal issued, and the record published to the public registry.
A property may appeal a finding; appeals are reviewed by an assessor who did not conduct the original audit.
Integrity commitments
The registry
Every certified property has a public record. Anyone can verify a seal — no login, no paywall.
Governance
The Certified Spaces Standard is maintained by Certified Spaces Standards Inc. with an independent advisory board drawn from the Building Biology Institutes. The standard is versioned and public; material changes are published with a changelog. Questions about the standard: jordan@humangarage.net.
