Harmon Guest House
227 Healdsburg Avenue, Healdsburg
The stay
Oak, reclaimed redwood and a rooftop over Fitch Mountain, from the team behind h2hotel.
Harmon Guest House is h2hotel’s younger sibling next door, thirty-nine rooms grouped in small pods around a glassed courtyard, each with a balcony or patio. The check-in desk is cut from a single fallen eucalyptus, and slatted redwood shades the street front. The rooftop looks across to Fitch Mountain and the Sonoma hills.
Before it opened, the owners said the building would use low- or no-VOC paints and coatings, solar water heating and rainwater for irrigation, and would aim for LEED Gold.1 The project architect lists it as LEED-certified, though its own page gives both Gold and Platinum.2 We have not yet confirmed what was built or how rooms are run day to day.
It is a warm, modern base in town, with the same small scale as its neighbor.

Building
The materials a hotel was built and renovated with, how it handles damp, and what third parties have certified.
Low-emitting materials
Not yet reviewed.
So far, the owners said in 2017: The build would use ‘low/no VOC paints & coatings’.
Our note. A pre-opening plan, not a record of what was built, and adhesives and flooring are not mentioned, so this falls short of the criterion.
How we know
What we look for. Low-VOC paints, adhesives, finishes and flooring specified in construction or renovation.
Why it matters. Paints, varnishes and adhesives release volatile organic compounds, formaldehyde among them, most heavily when new. Low-emitting products reduce that load.

Building certification
Hotel-reportedacross the property
The project architect lists: LEED New Construction certification, giving the level as both Gold and Platinum.
Our note. Not yet checked against the USGBC directory. Listed provisionally until the level is clear.
Shown for information; not scored.
How we know
What we look for. A third-party certification such as WELL, LEED or a green business program, recorded with its level, and its year where the certifier gives one.
Why it matters. WELL assesses air, water and light in occupied buildings. LEED and green business programs are mainly environmental, with some indoor-quality elements. A certificate records what was designed or checked at a point in time, not what a room is like today.
