Condo Conversions in Concord, CA

Concord has more genuine condominium work than any city we serve in central Contra Costa County. As the county's largest city, it carries a deep inventory of postwar apartment buildings, an actively repositioning downtown around the Concord BART stations, and aging commercial and industrial stock being converted to residential and mixed use. Whether the project is a new transit-oriented building mapped as condominiums from day one or an existing apartment complex converting to for-sale units, the surveying backbone is the same: a subdivision map processed under the Subdivision Map Act and a condominium plan under the Davis-Stirling Act defining units, common area, and exclusive-use areas such as balconies, garages, and assigned parking. We prepare both and coordinate recording with the Contra Costa County Recorder and map review with the County Surveyor in Martinez.

Concord adds a consideration few neighboring cities share: the Concord fault crosses the city and carries state Alquist-Priolo Earthquake Fault Zoning. That zoning does not prohibit conversions, but it does affect due diligence and disclosure for properties near the zone, and lenders and buyers of newly created units expect the mapping record to be handled carefully. We identify whether a property falls within the mapped zone during our boundary research so there are no surprises at the title or disclosure stage. On the boundary itself, we recover and preserve existing monuments as Business and Professions Code §8771 requires before any map records over them.

For apartment-to-condo conversions, the condominium plan must describe buildings that have often been remodeled, re-partitioned, and re-roofed over decades. Our Trimble terrestrial laser scanner captures every corridor, unit, and structural line in millions of survey-grade points during one visit — no unit-by-unit tape measuring, minimal tenant disruption — and the as-built survey we extract becomes the dimensional basis of the plan. Concord regulates conversions through its own application, noticing, and physical-standards process, so we align our mapping schedule with the city's requirements from the first meeting.
