Condo Conversions in Oakland, CA

We provide the surveying and mapping side of condominium conversions in Oakland, Alameda County: subdivision maps under the Subdivision Map Act, condominium plans under Davis-Stirling, and scan-based as-builts that make the recorded plan match the actual building.

Condo Conversions in Oakland: Local Conditions

Oakland has one of the East Bay’s deepest inventories of conversion candidates: West Oakland Victorians long ago split into flats, Rockridge and Temescal duplexes and triplexes, and warehouse buildings around Jack London Square already carved into lofts. Many of these are held as tenancies-in-common, and a TIC-to-condo conversion is fundamentally a mapping exercise. Two recorded documents do the legal work: a subdivision map processed under the Subdivision Map Act (a parcel map for four or fewer units, a tract map for five or more), and a condominium plan prepared under the Davis-Stirling Common Interest Development Act that defines each unit as a three-dimensional airspace, the common area, and any exclusive-use areas like decks, parking spaces, and storage. Both are recorded with the Alameda County Recorder, and the county surveyor reviews the map before it gets there.

The condominium plan must describe the building that actually exists — and Oakland’s older stock rarely matches original drawings. A 1905 Victorian converted to three flats has settled walls, out-of-square rooms, and additions that never saw a permit set. This is where our Trimble terrestrial laser scanner earns its keep: in one visit we capture every unit interior, the common stairs and halls, and the building exterior as millions of survey-grade points, then draft unit boundaries from measured surfaces rather than assumptions. No return trips to re-measure a closet that did not close, and the point cloud stands as a permanent record of unit geometry at the time of conversion. See as-built surveys for how that documentation works.

One caution we give every Oakland owner: California cities regulate conversions differently, and several East Bay cities — Oakland included — have local condominium conversion ordinances with their own eligibility and tenant-protection requirements. Confirming what the current local ordinance allows for your building is step one, before any survey work. Once the path is clear, we handle the boundary survey, the map, and the condominium plan as a single coordinated package.

Condo Conversions in Oakland: FAQ

Legally, a conversion runs through a subdivision map and a Davis-Stirling condominium plan, both of which we prepare. But Oakland, like several East Bay cities, has a local condominium conversion ordinance with its own eligibility and tenant-related requirements, and those rules change over time. We recommend confirming your building’s eligibility with the city as step one; the survey and mapping work follows once the path is clear.
Under the Subdivision Map Act, a conversion creating four or fewer condominium units generally proceeds by parcel map, while five or more units requires a tract map. A typical Oakland duplex or triplex conversion is therefore a parcel map project. Both are reviewed through the city and recorded with the Alameda County Recorder.
The condominium plan defines each unit by its physical boundaries, and Oakland’s Victorians and early-1900s flats rarely match any existing drawing. Scanning captures the true, as-settled geometry of every unit in one visit, so the recorded plan does not contradict the building. That accuracy prevents unit-boundary disputes later and eliminates repeat site visits.
