What Is a Lease Outline Drawing (LOD)?

A lease outline drawing is a measured floor plan used to define the space a tenant is leasing within a larger commercial building. You may also hear it called a lease exhibit floor plan or, in some contexts, a demising plan. Its job is straightforward: show the leased premises clearly enough that the landlord, tenant, broker, architect, and legal team all understand what is included, where the boundaries fall, and how the suite relates to corridors, exits, restrooms, and adjacent spaces.

For California landlords, property managers, and brokers, a lease outline drawing can prevent confusion before it turns into a dispute. It is often used as an exhibit to a lease, a reference for marketing available suites, or a starting document for a tenant improvement team. While it is not the same thing as a full permit-ready as-built set, it can be an essential first step in documenting a commercial space accurately. FastAsBuilt provides field-measured as-built drawings and measured floor plans across California, helping teams move from rough leasing information to dependable CAD files when accuracy matters.

What a lease outline drawing actually shows

A lease outline drawing focuses on the outline and limits of the leased premises. In most cases, that means a simplified plan view showing the tenant suite in relation to the rest of the floor. The drawing is not trying to document every construction detail. Instead, it identifies the footprint of the leased area and the physical context needed to understand it.

A typical lease outline drawing may include:

• Demising lines separating the tenant suite from neighboring spaces
• Suite number or space identifier
• Entry doors and primary access points
• Major walls and openings that define the premises
• Shared corridors, lobbies, or common areas near the suite
• Basic dimensions or boundary callouts
• North arrow and scale
• Labeling for restrooms, service areas, or other notable adjacent spaces when relevant

In leasing, the purpose is clarity. If someone reading the lease asks, “What exactly is the tenant renting?” the lease outline drawing should answer that question quickly.

Lease outline drawing vs. lease exhibit floor plan vs. demising plan

These terms overlap, but they are not always used in exactly the same way. In practice, many landlords and brokers use “lease outline drawing” and “lease exhibit floor plan” almost interchangeably. Both usually refer to a plan attached to a lease package that shows the leased premises. “Demising plan” often emphasizes the boundary itself—the line dividing one tenant area from another or from common space.

Here is a practical way to think about the three:

• Lease outline drawing: the general measured plan defining the leased space
• Lease exhibit floor plan: the version prepared to attach to lease documents as an exhibit
• Demising plan: a plan focused on the separation line between spaces, especially when new boundaries are being created or revised

On many projects, one drawing serves all three functions. For example, a broker may market a suite using a lease outline drawing, then legal may attach the same plan to the lease as an exhibit, and the architect may later use it to confirm demising assumptions for a tenant improvement concept. If you are unsure which level of detail is needed, it helps to start with the use case: marketing, lease attachment, planning, or permitting.

Why landlords, brokers, and tenants use one

A lease outline drawing solves a common commercial real estate problem: different people are often working from different assumptions about the same space. A broker may have an old flyer, the tenant may have a verbal understanding of what is included, and the building owner may be relying on outdated plans. A current measured drawing brings everyone back to the same page.

Common reasons to order a lease outline drawing include:

• Attaching a clear visual exhibit to a new lease or amendment
• Showing available premises for marketing and touring
• Clarifying what is exclusive tenant space versus common area
• Documenting a subdivision of a larger suite into smaller units
• Supporting rent discussions tied to area or suite configuration
• Giving architects and contractors a reliable starting point for future tenant improvements

In California, this is especially useful when buildings have been remodeled over time. Older office, retail, and industrial properties often have suites that do not perfectly match legacy plans. Walls move, storage areas get enclosed, entries are relocated, and former single-tenant spaces become multi-tenant layouts. A measured lease outline drawing can reveal those changes before they cause lease drafting issues or design rework.

If you are evaluating leasing documentation more broadly, this overview of as-built drawings for a commercial lease can help explain when a simple exhibit is enough and when a fuller drawing package is the better choice.

What a lease outline drawing does not replace

A lease outline drawing is useful, but it is not a substitute for every other type of building documentation. That distinction matters because landlords and tenants sometimes expect a basic lease exhibit to answer design, permit, or construction questions that require far more information.

A lease outline drawing usually does not include:

• Full architectural dimensions for every wall, room, and opening
• Reflected ceiling plans, lighting layouts, or power plans
• Detailed door and window schedules
• Structural, mechanical, plumbing, or fire protection information
• Code analysis or occupancy calculations
• Permit-ready elevations and sections unless specifically commissioned

That is where field-measured as-built drawings come in. FastAsBuilt measures on site with laser equipment, then senior drafters prepare CAD files in PDF and DWG format. For commercial projects that may proceed into design or permit review, that extra detail can save time later. If your lease outline drawing is really the first step toward a build-out, it is worth looking at how commercial as-built drawings work before you decide on scope.

When you should order a measured LOD instead of using an old plan

Many lease transactions begin with an existing floor plan from the owner’s file, a prior broker package, or a scan of an old blueprint. Sometimes that is enough for a quick conversation. But if the plan is going to be attached to a lease, relied on for space planning, or used to support a demising decision, a measured drawing is often the safer option.

You should strongly consider a measured lease outline drawing when:

• The available plan is several years old
• The suite has been altered since the last drawing was made
• There is uncertainty about the exact tenant boundary
• The building has irregular geometry or multiple access paths
• The premises are part of a pending split or combination of suites
• The drawing will be used downstream for design or permit discussions

Measured plans are also helpful in office and retail buildings where circulation and visibility matter. A small discrepancy in corridor width, storefront line, or service area location can affect layout assumptions. In industrial and warehouse properties, the same issue can appear around office pods, restrooms, loading access, and areas carved out from a larger floor plate.

How lease outline drawings relate to square footage questions

One reason lease outline drawings create so much interest is that they sit close to square footage discussions, but they do not automatically settle them. A drawing can show boundaries clearly without being a formal rentable area calculation. That distinction is important for brokers and landlords who need to avoid mixing visual documentation with a specific measurement standard unless that standard has actually been applied.

For example, a lease outline drawing may show the suite perimeter and dimensions, but rentable square footage may still depend on building load factors, common area allocations, or a standard such as BOMA if the parties are using one. Likewise, usable area may differ from rentable area. The drawing helps define the premises physically; the lease and measurement methodology determine how area is counted.

That is why a good practice is to label the drawing carefully and make sure any area number shown is consistent with the leasing standard being used. If the transaction involves area-sensitive economics, you may also want to review rentable vs. usable square footage and what BOMA square footage measurement means so the visual exhibit and the deal terms line up.

What information to provide before ordering one

You do not need a perfect package to get started, but a little preparation helps the drafting process go faster. When requesting a lease outline drawing, try to gather the most current information you have about the building and the target suite.

Useful items to share

• Property address and suite number
• Any prior floor plans, even if outdated
• A site or floor directory if the suite is hard to locate
• Notes about recent renovations or planned demising changes
• Your intended use of the drawing: marketing, lease exhibit, planning, or TI kickoff
• Whether you need PDF only or CAD files as well

If your team already knows the plan may lead into permitting, say so up front. That can affect the recommended scope. FastAsBuilt offers 2D as-built plans starting at $900 for up to 1,500 square feet, then $0.50 per square foot, with one revision and typical 48–72 hour delivery. For projects needing a model and a fuller documentation set, 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 two revisions and typical 3–5 business day delivery. Custom commercial scopes are quoted individually.

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

If you are comparing options now, you can review packages to see which type of deliverable best matches your leasing or pre-construction needs.

How the FastAsBuilt process works for commercial spaces

For a lease outline drawing or broader as-built package to be dependable, it should begin with the actual space—not assumptions. FastAsBuilt uses on-site laser measurement, then senior drafters convert those field measurements into organized CAD drawings. That process is especially valuable in California commercial buildings where existing records may be inconsistent or incomplete.

The workflow is simple:

• A local crew visits the site and measures the premises
• Key boundaries, walls, openings, and spatial relationships are documented
• Senior drafters prepare the drawing set in CAD
• Files are delivered in PDF and DWG format

FastAsBuilt serves Southern California, including Los Angeles, Orange County, and the Inland Empire, as well as the Bay Area and San Diego. That local coverage matters because access coordination, building types, and jurisdictional expectations can vary significantly across the state. While a lease outline drawing itself is typically a private transaction document rather than a permit submittal, many clients choose a measured plan because they know the space will likely move into architecture, engineering, or city review later.

California situations where an LOD is especially helpful

Commercial leasing in California often intersects with later compliance, improvement, or change-of-use work. A lease outline drawing will not answer every legal or code issue, but it can help define the exact premises before those next steps begin.

Examples include:

• Tenant improvements: If a new tenant expects office, retail, or restaurant improvements, an accurate suite outline helps the design team start correctly.
• Change of occupancy discussions: If the intended use may differ from the previous tenant’s use, the boundary and layout should be clearly documented before planning begins.
• ADA upgrade planning: If accessibility improvements may be needed, knowing what is inside the premises versus common area is important for scope discussions.
• Multi-tenant reconfiguration: If a landlord is splitting one suite into two, a demising plan becomes central to the transaction and the future construction package.

California rules on accessibility, energy compliance such as Title 24, and local permitting can all affect what happens after lease signing. The exact requirements depend on the city, county, building type, and scope of work, so you should always confirm details with the local jurisdiction and your design professionals. The lease outline drawing is not the compliance solution by itself, but it gives everyone a reliable map of the premises before those questions are addressed.

For more detail on common next steps, you may want to read about change of occupancy drawing issues or ADA compliance upgrade documentation.

Best practices for using a lease outline drawing in a lease package

If the drawing is going to be attached as an exhibit, presentation matters almost as much as accuracy. A lease outline drawing should be easy for a nontechnical reader to understand. Legal teams, brokers, and tenants should not have to decode the exhibit.

Best practices include:

• Clearly shade or outline the leased premises
• Label adjacent suites, corridors, and common areas where relevant
• Show entrances and any areas of non-exclusive access if needed
• Use consistent suite names and numbering across the lease and the drawing
• Distinguish approximate planning information from measured information
• Note if the exhibit is for identification of premises and not a guaranteed area calculation, if that matches the transaction structure

It is also wise to decide early whether you need a simple black-and-white exhibit or a cleaner presentation version for marketing and negotiations. In many cases, both are useful: one polished plan for brochures and one measured lease exhibit floor plan for the legal package. If the same drawing may later support contractor pricing or permit work, a fuller as-built scope can be more efficient than recreating the work from scratch.

Frequently asked questions

Is a lease outline drawing the same as an as-built drawing?

No. A lease outline drawing is usually narrower in scope. It defines the leased premises and nearby context, while an as-built drawing set documents the existing conditions of the space in greater detail. If your project is likely to move into design, permitting, or construction, full measured as-builts may be the better long-term choice.

Can a lease outline drawing be used as a lease exhibit floor plan?

Yes. In many transactions, the lease outline drawing becomes the lease exhibit floor plan attached to the signed lease. The key is making sure the drawing is clear, accurate, and consistent with the premises description in the legal documents.

When is a demising plan needed instead of a basic LOD?

A demising plan is especially useful when suite boundaries are being created, moved, or reworked. If a landlord is splitting a larger space, combining suites, or negotiating exactly where a tenant boundary will fall, the demising line needs special attention. In that situation, a simple generic outline may not be enough.

Does a lease outline drawing establish official square footage?

Not by itself. It can support square footage discussions, but official rentable or usable area depends on the measurement method being used and the deal terms in the lease. If area is financially important to the transaction, make sure the drawing and the lease use the same standard and language.

How fast can FastAsBuilt deliver commercial measured plans?

For 2D as-built plans, typical delivery is 48–72 hours, with pricing starting at $900 for up to 1,500 square feet, then $0.50 per square foot. For 3D as-built plans, typical delivery is 3–5 business days, with pricing starting at $1,500, then $1.00 per square foot. Custom commercial projects, including tenant improvements and other nonstandard scopes, are quoted individually.

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

Bottom line

A lease outline drawing is a practical, high-value document for defining commercial leased space clearly. Whether you call it a lease outline drawing, lease exhibit floor plan, or demising plan, the goal is the same: remove guesswork about the premises before leasing, planning, or improvement work moves forward. In California, where older buildings, evolving suite layouts, and downstream permit issues are common, a measured drawing can save time and reduce confusion. When you need dependable documentation, FastAsBuilt can measure the space on site and deliver clear CAD files that support leasing now and better decisions later.
