What could be built here

A screen, not a determination

ADU or junior ADU

Likely eligible

Zoned D-DT-JLI (mixed use): state law allows ADUs where homes are allowed.
We read D-DT-JLI from the zoning code's name; we haven't checked it against Oakland's code text.
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 D-DT-JLI (mixed use), not a single-family residential zone.
We read D-DT-JLI from the zoning code's name; we haven't checked it against Oakland's code text.

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Whether a tenant lived there in the last 3 years, or the building was withdrawn from rent under the Ellis Act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 D-DT-JLI (mixed use), not a single-family residential zone.
We read D-DT-JLI from the zoning code's name; we haven't checked it against Oakland's code text.

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Whether a tenant lived there in the last 3 years, or the building was withdrawn from rent under the Ellis Act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 X: minimal flood hazardFIRM panel 06001C0067H, effective December 21, 2018. Official flood map

We don't have building permits for Oakland, so we can't show what has been permitted nearby.

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 Oakland's planning department before relying on it.

Rental regulatory context (informational only — not legal advice):

California AB 1482 (Tenant Protection Act, Civ. Code § 1947.12) caps annual rent increases at 5% + local CPI (max 10%) on covered properties. In Oakland: Oakland Rent Adjustment Program (OMC Ch. 8.22) — annual CPI adjustment (60% of CPI, capped at 3.0%) for covered pre-1983 multifamily units. Official program rules ↗

Common statutory exemption signals under AB 1482

Housing issued a certificate of occupancy within the last 15 years (rolling exemption under AB 1482).
Separately alienable single-family homes or condominiums not owned by a corporation, REIT, or LLC with a corporate member (when required statutory notice is in the lease).
Owner-occupied duplexes where the owner occupied one unit from the start of the tenancy.
