Existing Condition Drawings capture what truly exists on site not assumptions, not outdated plans.
We document buildings as they stand today through detailed on-site measurements, helping architects, engineers, and property owners make confident decisions before design, renovation, or permitting begins.
Our drawings provide a clear, verified representation of existing architectural and structural conditions, reducing uncertainty and setting a strong foundation for every project phase.
Existing Condition Drawings are detailed drawings that document the actual, current condition of a building or space based on real on-site measurements and visual verification. These drawings show what is physically present today including layouts, dimensions, walls, openings, and visible building elements without relying on original plans or assumptions.
They are commonly used as a starting point for renovations, remodels, tenant improvements, permitting, and future planning. By providing an accurate snapshot of existing conditions, these drawings help project teams avoid surprises, reduce design conflicts, and move forward with clarity and confidence.

We also support projects that involve phased renovations or large, complex structures.
We follow a structured and streamlined approach to capture existing conditions accurately from the start. This reduces guesswork, shortens planning timelines, and helps projects move forward without unnecessary delays or back-and-forth revisions.
Our existing condition drawings support a wide range of commercial needs—from early feasibility studies and space planning to renovations, leasing documentation, and long-term asset management. The drawings are adaptable and easy to reuse as project requirements evolve.
Accuracy is at the core of our work. Through careful on-site measurements and detailed verification, we ensure the drawings reflect what truly exists in the field, helping teams make confident decisions and avoid costly surprises later.
Commercial buildings often come with irregular layouts, phased modifications, or undocumented changes. We tailor our documentation approach to each site’s unique challenges, delivering clear and dependable drawings regardless of size or complexity.
Existing condition drawings are accurate representations of a building’s current physical state. These drawings document what actually exists on site, including layouts, dimensions, and fixed elements, regardless of original design intent. They are created through on-site verification to reflect real conditions, not assumptions or outdated records.
Existing condition drawings are needed before renovations, space reconfigurations, adaptive reuse projects, or property evaluations. They are especially important when original drawings are missing, incomplete, or no longer reflect the current layout. Designers and owners rely on them to make informed decisions before any changes begin.
Existing condition drawings can be prepared for offices, retail spaces, residential units, mixed-use buildings, industrial facilities, and institutional properties. Any space that requires accurate documentation of its current layout and conditions can benefit from this service.
These drawings usually include floor plans with accurate dimensions, wall locations, door and window placements, ceiling heights, and fixed architectural elements. Depending on the project scope, they may also show visible structural components and permanent fixtures that define the space.
Existing condition drawings are based on field measurements and on-site observations to ensure a high level of accuracy. They reflect real-world conditions at the time of documentation, helping reduce design conflicts and unexpected issues during planning or construction.
The timeline depends on the size and complexity of the space being documented. Smaller areas can be completed quickly, while larger or multi-level buildings may require additional time for measurement and drafting. Accuracy is always prioritized over speed.
Yes. Existing condition drawings serve as a reliable foundation for future design, renovation, and planning work. They help architects, engineers, and property owners work from accurate information, saving time and minimizing revisions as projects move forward.
