1 Barbaree Way, Tiburon · Parcel Context

What could be built here

A screen, not a determination

ADU or junior ADU

Likely eligible

Zoned RMP-18.1-BFC (multifamily residential): state law allows ADUs where homes are allowed.
On a multifamily lot the state allowance is different: ADUs in non-living space of the building, plus up to eight detached ADUs.

What we couldn't check (4)

Setbacks, height and size limits in the local ADU ordinance
Utility and sewer capacity, fire access
Historic district or landmark status: we have no historic layer for this area yet.
Locally adopted fire hazard maps, which can be broader than the State's.

SB 9: two homes on the lot

Unlikely

Zoned RMP-18.1-BFC (multifamily residential), not a single-family residential zone.

What we couldn't check (6)

Whether a tenant lived there in the last 3 years, or the building was withdrawn from rent under the Ellis Act
Rent-controlled or deed-restricted affordable housing on the lot
Wetlands, habitat, farmland, hazardous waste sites and conservation easements
Local SB 9 standards (size, setbacks, parking)
Historic district or landmark status: we have no historic layer for this area yet.
Locally adopted fire hazard maps, which can be broader than the State's.

SB 9: split into two lots

Unlikely

Zoned RMP-18.1-BFC (multifamily residential), not a single-family residential zone.

What we couldn't check (6)

Owner-occupancy: the applicant must sign an affidavit to live in one of the homes for 3 years
Whether the lot was created by an earlier SB 9 split, or the owner split an adjacent lot
Whether a tenant lived there in the last 3 years, or the building was withdrawn from rent under the Ellis Act
Wetlands, habitat, farmland, hazardous waste sites and conservation easements
Historic district or landmark status: we have no historic layer for this area yet.
Locally adopted fire hazard maps, which can be broader than the State's.

Mapped hazards on this lot

Fire hazard severity zone: Not in a State-mapped zone
FEMA flood zone: Zone AE: 1% annual chance flood (Special Flood Hazard Area), about 82% of the lotZone X: 0.2% annual chance flood hazard (shaded X), about 7% of the lotZone X: minimal flood hazard, about 6% of the lotZone AE: 1% annual chance flood (Special Flood Hazard Area), about 5% of the lotFIRM panel 06041C0488E, effective March 16, 2016. Official flood map
Earthquake fault zone: Not in an Alquist-Priolo Earthquake Fault Zone

Built nearby: within ¼ mile since October 2023

No ADU or new-home permits recorded within ¼ mile in this window.

Permit counts, by the date issued (or applied, if not yet issued). Lot splits are planning cases, which we don't have.

We read public zoning and hazard maps against state law (ADUs: Gov. Code 66314; SB 9: Gov. Code 65852.21 and 66411.7). Local rules, title, tenancy history and site conditions can change the answer. Check with Unincorporated Marin's planning department before relying on it.
