Contour Survey

Condominium Conversion Surveys & Interior As-Built Scanning

Convert existing buildings into condominium ownership with 3D laser scanning, accurate interior and exterior as-builts, and boundary coordination. Scanning is uniquely suited to condo conversion work — it captures complete unit, common area, and exclusive-use area geometry in a fraction of the field time of hand measurement, and gives developers, architects, attorneys, and HOA teams a reliable record before filings become expensive.

Better Existing-Building Data for Conversion Teams

Condominium conversions combine building geometry, ownership boundaries, common areas, exclusive-use areas, agency requirements, and legal documentation. We help teams understand the physical building before drawings and filings get expensive.

Useful Early Questions

Do the existing plans match the building?

Where are unit, common, and exclusive-use area assumptions coming from?

What boundary, mapping, or agency survey requirements may apply?

Which deliverables do the architect and attorney need first?

1

Conversion Review

We review the existing building, title context, jurisdiction requirements, and intended ownership structure.

2

Interior & Boundary Survey

We capture building interiors, exterior limits, relevant site features, and property boundary information.

3

Plan Coordination

We prepare survey and as-built information that supports architects, attorneys, and agency submittals.

4

Filing Support

We help coordinate the survey components needed for the condominium conversion and related mapping process.

Condo Conversions FAQ

Existing buildings rarely match old plans. Scanning helps document interior geometry, unit boundaries, common areas, stairs, corridors, and exterior relationships with fewer site revisits.
We commonly coordinate with architects, civil engineers, real estate attorneys, developers, HOA consultants, and agency reviewers.
Yes. Early survey and as-built documentation can reveal geometry, boundary, and documentation issues before they become schedule or filing problems.

Boundary Determination

Establish clear, legally defensible property boundaries with a licensed Bay Area boundary surveyor — including difficult boundaries on hillside lots, irregular parcels, post-1906 SF blocks, fire-rebuild areas, and properties with conflicting record evidence.

Subdivisions

Navigate the complex subdivision process with expert guidance.

3D Scanning

Capture existing conditions once and give every stakeholder a reliable source of truth.
