As-Built Cost for an Office Tenant Improvement

If you are budgeting a tenant improvement for an office, one of the first line items to clarify is the office ti as-built cost. Before a designer, architect, engineer, or contractor can plan new walls, revise life-safety layouts, or coordinate MEP changes, they need a reliable record of what exists today. That means measured floor plans and, in many cases, elevations, sections, and a model that reflects the actual space instead of old leasing plans or incomplete record drawings.

In California, office TI pricing is shaped by more than just square footage. The size of the suite matters, but so do building access rules, ceiling complexity, mezzanines, shared-core conditions, and whether your team needs simple 2D plans or a fuller 3D as-built package. FastAsBuilt provides field-measured as-built drawings and measured floor plans across California using on-site laser measurement, followed by senior drafters who produce permit-ready CAD files in PDF and DWG format. This guide explains how to think about cost, what is typically included, and how to avoid buying the wrong scope.

Why as-builts matter before an office tenant improvement

An office tenant improvement starts with existing conditions. Even in newer buildings, leasing brochures, marketing floor plans, and prior construction sets often do not match the current built condition. Suites may have been combined, demising walls may have shifted, doors may have moved, and the reflected ceiling plan may no longer align with mechanical distribution. If your design team starts from inaccurate base drawings, errors tend to spread through the project.

Measured as-builts reduce that risk by giving your team a reliable base layer for planning. For a typical office TI, that often means:

• Verifying room dimensions and overall suite boundaries
• Capturing corridor relationships, entries, and common-area interfaces
• Documenting windows, doors, and major openings
• Recording ceiling heights, soffits, and other features that affect design
• Creating CAD files your architect and consultants can build on

If you are comparing this service with generic sketching or an old PDF from property management, it helps to understand what as-built drawings are and why they are different from conceptual floor plans. In commercial TI work, that difference often saves time during design development and permit review.

What the office ti as-built cost usually includes

When clients ask about office TI as-built cost, they usually want to know what they are actually buying. At FastAsBuilt, the process begins with an on-site laser measurement by local crews serving Southern California, the Bay Area, and San Diego. After field work, senior drafters turn that measured information into permit-ready CAD files delivered in PDF and DWG.

For many office suites, the core service includes:

• Site visit and field measurement
• Drafting of existing floor plans
• Dimensioned plans suitable for design and permit coordination
• Digital delivery in PDF and DWG formats

Depending on the package, scope can also include elevations, sections, and a 3D model. That broader documentation is often useful when the TI affects storefronts, reception features, interconnecting stairs, double-height spaces, unusual bulkheads, or complex ceiling and wall relationships. If you are weighing format options, this comparison of 2D vs. 3D as-built plans is a good starting point.

For commercial spaces, the exact deliverables should be confirmed before the field visit. A suite-level TI may only need floor plans, while a larger repositioning project may need more detailed vertical information. That is why custom commercial projects are usually quoted individually.

Baseline pricing: 2D, 3D, and custom commercial quotes

FastAsBuilt’s baseline pricing provides a useful starting point, even though office tenant improvements often require a custom commercial quote.

• 2D As-Built Plans: starting at $900 for up to 1,500 square feet, then $0.50 per square foot. This includes 1 revision and typical delivery in 48–72 hours. Turnaround times are estimates and may vary based on project complexity and scheduling.
• 3D As-Built Plans: starting at $1,500, then $1.00 per square foot. This includes a 3D model plus 2D floor plans, elevations, and sections, 2 revisions, and typical delivery in 3–5 business days. Turnaround times are estimates and may vary based on project complexity and scheduling.
• Custom projects: commercial work, including office tenant improvements, is quoted individually based on scope.

That means the office ti as-built cost for a simple, open office suite may track close to baseline 2D or 3D pricing, while a more complex project may be priced beyond those starting numbers because it requires additional detail, multiple areas of access, or expanded deliverables. If you want broader context on market expectations, you can also review how much as-built drawings cost and how pricing structures tend to work.

For budgeting purposes, it helps to think in tiers:

• Simple TI: one suite, mostly open plan, standard ceiling conditions, clear access
• Moderate TI: several offices and conference rooms, mixed ceiling heights, more openings and built-ins
• Complex TI: large footprint, partial floors or multiple suites, irregular geometry, mezzanines, or detailed vertical conditions

The more your project moves from simple to complex, the less useful a generic square-foot price becomes by itself.

What drives office TI pricing beyond square footage

Square footage is important, but it is only one variable in as-built drawings cost. In office work, the biggest pricing drivers are usually the amount of detail to capture and the time it takes to measure and draft accurately.

Layout complexity

A rectangular suite with a few rooms can be measured faster than a space with many private offices, phone rooms, storage spaces, angled walls, or curved glazing. Every added condition introduces more field verification and drafting time.

Ceiling and vertical conditions

Some office TIs are mostly about partition changes and furniture planning. Others depend on soffits, bulkheads, ceiling height transitions, and sections through stairs or double-height areas. If your permit set will rely on those conditions, the scope increases.

Access and building logistics

Downtown high-rises, medical office buildings, and secured campuses can require check-in procedures, certificates of insurance, loading coordination, after-hours access, or escort rules. Those practical details affect field time and scheduling.

Occupied versus vacant suites

An empty shell or recently vacated office is generally faster to document than a fully occupied space with furniture, stored files, and active staff. Occupancy can limit sightlines and slow measurement.

Scope of deliverables

A plan-only package costs less than a package that includes elevations, sections, and a 3D model. If your architect needs a richer existing-conditions package, the price will reflect that broader output.

These are many of the same variables covered in what affects the cost of as-built drawings. For office TI projects, those factors often matter more than clients expect at the beginning.

When 2D plans are enough for an office TI

Many office tenant improvements do not need a full 3D package. If your project is a straightforward interior reconfiguration and your design team mainly needs an accurate base floor plan, 2D as-builts may be the most efficient option.

2D plans are often enough when:

• The suite has standard ceiling heights and no unusual vertical transitions
• The TI focuses on partitions, doors, and room layout
• Your team already has reliable information for some vertical elements
• The permit submittal will be based mostly on plan-level changes

For these projects, the value is speed and cost control. FastAsBuilt’s 2D As-Built Plans start at $900 for up to 1,500 square feet, then $0.50 per square foot, with 1 revision and typical 48–72 hour delivery. That can be a practical fit when timing is tight and the scope is limited to floor-plan documentation.

Turnaround times are estimates and may vary based on project complexity and scheduling.

Still, not every office TI should default to the lowest-cost option. If your team later realizes they need sections, elevations, or more detailed representation of the existing space, the initial savings may be offset by added back-and-forth. A short scope review before ordering is the best way to prevent that mismatch.

When 3D as-builts make more sense

3D as-built plans are usually worth considering when the TI scope depends on the real shape and volume of the space, not just room-to-room dimensions. In office environments, that can apply to creative offices, converted industrial buildings, two-story suites, or projects where feature walls, stair enclosures, and ceiling conditions play a major role.

FastAsBuilt’s 3D As-Built Plans start at $1,500, then $1.00 per square foot, and include a 3D model plus 2D floor plans, elevations, and sections, with 2 revisions and typical delivery in 3–5 business days.

Turnaround times are estimates and may vary based on project complexity and scheduling.

That broader package can make sense if your project involves:

• Interiors with varying heights, soffits, or exposed structure
• Reception areas or amenity spaces where elevations matter
• Stairs, mezzanines, or partial upper levels
• Facade or storefront changes tied to the tenant space
• Coordination across architecture, engineering, and contractor teams

For some clients, the question is not just cost but efficiency across the full project timeline. A better base model can reduce redesign, especially when multiple consultants are working from the same existing-conditions set.

How California permit context can affect scope

California office TI work is local by nature. Even when the suite is small, permit expectations vary by city, county, and building department. As-built documentation is not the permit set itself, but it forms the base that permit drawings depend on. The cleaner and more accurate that base is, the easier it is for your architect and consultants to move into compliance drawings.

Several California-specific issues can influence how much existing-condition information your team wants up front:

• Accessibility upgrades: tenant improvements may trigger review of accessible routes, restrooms, counters, and path-of-travel items depending on project scope and local interpretation.
• Energy compliance: Title 24 can affect lighting, controls, envelope elements, and mechanical work. Existing conditions may need to be documented clearly so the design team can determine what is changing and what remains.
• Change-of-use or occupancy questions: some projects blur the line between standard office improvements and more specialized commercial uses.
• Landlord and building-management requirements: many office buildings require plan review packages that go beyond the city permit submittal.

Because local review standards differ, it is wise to confirm scope expectations with your architect and the local jurisdiction before ordering. That is especially true if the TI includes egress changes, structural work, storefront revisions, or shared common-area interfaces.

Turnaround, revisions, and scheduling for commercial projects

Cost is only part of the equation. In tenant improvement work, schedule can be just as important. Leasing timelines, contractor bidding, landlord review, and permit submission dates often put pressure on the as-built phase.

FastAsBuilt’s typical turnaround is:

• 2D As-Built Plans: 48–72 hours, with 1 revision Turnaround times are estimates and may vary based on project complexity and scheduling.
• 3D As-Built Plans: 3–5 business days, with 2 revisions Turnaround times are estimates and may vary based on project complexity and scheduling.

For office TI projects, the key is to distinguish between standard turnaround and total project time. Access coordination, building rules, and the size of the commercial scope can all affect the schedule around the field visit itself. A project may move quickly once measurement is complete, but getting the site visit approved can take planning.

To keep your timeline on track:

• Confirm who controls access to the suite and common areas
• Decide whether measurements must happen after hours
• Clarify exactly which drawings your architect needs
• Share any old PDFs or landlord plans as reference only
• Identify whether one area or several connected spaces must be captured

If you are ready to move from budgeting to ordering, you can start through the order page and confirm the commercial scope needed for your TI.

How to budget accurately without under-scoping the job

The most common budgeting mistake with office TI as-built cost is assuming the lowest possible floor plan pricing applies to every commercial space. In reality, under-scoping can lead to change orders in the broader project, delays for the architect, or the need to send someone back to verify missing conditions.

A better approach is to budget in three steps.

1. Define the real use of the drawings

Ask whether the as-builts are only for test fits, or whether they will be the base for permit drawings and consultant coordination. Permit-ready use generally calls for more disciplined deliverables than early concept planning.

2. Identify the minimum necessary output

Do you need only a measured floor plan, or also elevations, sections, and a model? The answer changes pricing more than many clients expect. If your project will likely need vertical information later, it can be smarter to include it at the start.

3. Account for field realities

Occupied space, high-rise access, restricted hours, and large common-area interfaces all affect effort. Budget discussions should reflect those realities rather than just rentable square footage.

For more context on why pricing is structured this way, see why as-built drawings cost what they do. Understanding the service helps you compare quotes more fairly and avoid false apples-to-apples comparisons.

Frequently asked questions

How much does office ti as-built cost for a small office suite?

For a simple office suite, pricing may align with baseline 2D or 3D starting rates, but most office tenant improvements are treated as custom commercial quotes. FastAsBuilt’s 2D As-Built Plans start at $900 for up to 1,500 square feet, then $0.50 per square foot. 3D As-Built Plans start at $1,500, then $1.00 per square foot. The final price depends on complexity, access, and deliverables.

What is included in permit-ready CAD files?

FastAsBuilt uses on-site laser measurement and senior drafters to produce permit-ready CAD files delivered in PDF and DWG. For 2D projects, that typically means measured floor plans. For 3D projects, the package includes a 3D model plus 2D floor plans, elevations, and sections. Your architect may still add project-specific code, structural, accessibility, and engineering information for permit submission.

Are office as-built drawings costed by the hour or by square foot?

Commercial clients often think in square footage, but office TI pricing is not purely formula-based. Baseline residential-style pricing can provide a rough reference, yet custom office projects are usually quoted individually because layout complexity, building logistics, and required deliverables matter so much. If you are comparing pricing methods, this article on whether as-built drawings are billed hourly explains the logic behind different quote structures.

How long does it take to get office as-builts back?

Typical delivery is 48–72 hours for 2D As-Built Plans and 3–5 business days for 3D As-Built Plans. For office tenant improvements, actual scheduling also depends on when the field visit can happen and whether the building has access restrictions or after-hours requirements.

Turnaround times are estimates and may vary based on project complexity and scheduling.

Do I need 3D as-builts for every office tenant improvement?

No. Many office TIs only need accurate 2D measured floor plans. A 3D package becomes more useful when the project depends on elevations, sections, height changes, stairs, mezzanines, storefront conditions, or more complex consultant coordination. The right choice depends on how the drawings will be used, not just on the desire to minimize upfront cost.

Bottom line

The right office ti as-built cost is the one that matches your actual project needs. A simple office reconfiguration may fit within baseline 2D floor plan pricing, while a more complex tenant improvement often calls for a custom commercial quote with broader deliverables. In California, reliable as-builts start with on-site laser measurement and end with accurate PDF and DWG files your team can use for design and permit work. If you want to budget well, focus on scope, access, and intended use—not just square footage alone.
