How to Get a Floor Plan of an Apartment

If you need a floor plan of an apartment and no plan is available from the owner, HOA, property manager, or original builder, the fastest path is usually to have the unit measured on site and drafted into a clean digital plan. That approach gives you an apartment floor plan based on the actual conditions you can see today, rather than an old marketing flyer or an incomplete permit sheet.

For California owners, buyers, agents, landlords, architects, and contractors, the right plan depends on what you need to do next. A simple unit floor plan may be enough for a listing, space planning, leasing, or documentation. If you are preparing for renovation, permit work, or coordination with a designer, you may need a more complete condo plan or as-built package that reflects walls, doors, windows, fixtures, and key dimensions.

Start by checking whether a plan already exists

Before paying to measure the unit, it makes sense to look for existing documents. Some apartments and condos have original plan sheets in a property file, offering memorandum, or HOA archive. In other cases, the only available plan is a simplified marketing layout that is useful for orientation but not reliable for design or permitting.

Good places to check include:

• The current owner or landlord
• The HOA or building management office
• The original developer, if the building is newer
• Your purchase or lease documents
• Past listing materials
• Your architect, designer, or contractor if they have worked on the unit before

If you find a plan, verify whether it matches the current layout. Units often change over time. Interior partitions move, closets are altered, kitchens are reworked, and fixtures are replaced. Even when an old drawing exists, it may not reflect the apartment as it stands now. If you need dependable documentation, measured as-built drawings are usually the safer choice. For a broader overview of the document type, see what as-built drawings are.

Know when a measured apartment floor plan is the better option

A field-measured floor plan of an apartment is usually the right solution when no trustworthy plan exists, when the unit has been remodeled, or when the next step requires dimensions that a brochure layout cannot provide. In California, this comes up often with older condo buildings, small multifamily properties, inherited units, and properties changing hands after years without updated records.

You may want a measured apartment floor plan if you are:

• Listing a unit for sale or lease
• Planning furniture layouts or tenant improvements
• Starting a kitchen or bath remodel
• Preparing a designer or architect to propose changes
• Documenting an existing unit before construction starts
• Trying to confirm room sizes and overall layout
• Needing a current condo plan for building coordination

The main advantage is accuracy based on on-site measurement. FastAsBuilt uses laser measurement in the field, then senior drafters turn those notes into permit-ready CAD files. You receive digital drawings in PDF and DWG format, which are easier to share with agents, owners, designers, and contractors than a hand sketch or scanned flyer.

Understand the difference between listing plans and as-built plans

Not every floor plan serves the same purpose. A real estate listing plan is usually created to help a buyer or renter understand the flow of the space. It may highlight room names, approximate dimensions, and a clean visual presentation. An as-built plan is more technical. It is meant to record what exists in the unit now and support design, pricing, planning, and in some cases permit preparation.

That difference matters if you are deciding how much detail to order. A simple apartment floor plan might be enough for marketing a unit. A renovation team will usually want a more complete measured set. If your project may move toward permits, it helps to start with stronger base drawings. You can also compare the use case with getting a floor plan for a real estate listing.

Typical details in a measured unit floor plan

• Overall unit layout
• Room names and circulation
• Wall locations
• Doors and windows
• Kitchens and bathrooms
• Major built-in features visible on site
• Dimensions needed for planning and drafting

If you are unsure what level of detail you need, it helps to think backward from the decision you are trying to make. Selling and leasing usually need clarity. Remodeling usually needs precision. Permitting usually needs the strongest documentation of existing conditions.

How the measurement process works in California

For most units, the process is straightforward. A local field crew visits the apartment, condo, or multifamily unit and captures measurements on site using laser tools. After that, senior drafters prepare the drawing set in CAD. This workflow is especially helpful when you need a fast turnaround without trying to measure rooms yourself.

FastAsBuilt serves Southern California, including Los Angeles, Orange County, and the Inland Empire, along with the Bay Area and San Diego. That local coverage matters because access, parking, occupied units, and building rules can affect scheduling in different parts of California.

Here is the usual sequence:

• Schedule the site visit
• Provide the unit address and any access notes
• Allow the field crew to measure the apartment on site
• FastAsBuilt drafts the measured conditions into CAD
• You receive PDF and DWG files
• You review the plans and request revisions if needed

For a closer look at the workflow, see how as-built drawings are made. If you are ready to move forward, you can place a request through the order page.

What to expect in the deliverables

When people ask for a floor plan of an apartment, they often mean different things. Some want one clean floor plan sheet. Others need a package that can support design development or permit work. FastAsBuilt offers both 2D and 3D as-built options, and the better fit depends on how the plan will be used.

2D as-built plans

2D As-Built Plans start at $900 for up to 1,500 square feet, then $0.50 per square foot. They include one revision and are typically delivered within 48 to 72 hours. This option is often a practical fit for a standard apartment floor plan, condo plan, or unit floor plan when you need current measured drawings without a 3D model.

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

3D as-built plans

3D As-Built Plans start at $1,500, then $1.00 per square foot. They include a 3D model plus 2D floor plans, elevations, and sections, with two revisions and typical delivery in 3 to 5 business days. This option is useful when you want a fuller record of the apartment for redesign, coordination, or presentation.

For larger or more specialized work, such as commercial spaces, ADUs, SB9 projects, or tenant improvements, FastAsBuilt quotes each project individually. That can be relevant for mixed-use buildings, combined units, or situations where the apartment is part of a larger scope.

How to prepare for the site visit

You do not need to do much to get a usable floor plan of an apartment, but a little preparation can make the measuring appointment smoother and reduce questions later. The main goal is clear access to all parts of the unit that need to appear on the drawing.

• Confirm access with the occupant, owner, or property manager
• Make sure all rooms can be entered
• Unlock storage areas, balconies, or utility closets if they are part of the scope
• Secure pets and remove any obstacles blocking walls or doors
• Share any old plans, sketches, or renovation notes you already have
• Mention any specific concern, such as a converted den or enclosed patio

If the unit is occupied, it helps to set expectations ahead of time. The field visit is usually efficient, but access issues can slow things down. In apartment and condo buildings, elevators, parking rules, front desk procedures, and HOA access windows can also affect timing.

One more practical point: if you only need a clean apartment floor plan for planning or marketing, say so up front. If you may use the drawings for a remodel or permit application later, mention that too. The intended use helps define the best deliverable from the beginning.

Common California use cases for apartment and condo plans

California property owners and professionals ask for measured unit plans for many reasons. In some cases, the plan is simply about clarity. In others, it is the base document that allows a larger project to move forward with fewer assumptions.

Common use cases include:

• Real estate listings that need a clear, current apartment floor plan
• Condo purchases where the buyer wants to understand the existing layout
• Remodel planning for kitchens, bathrooms, and interior reconfiguration
• HOA review packages that need an existing unit layout
• Tenant improvement planning in mixed residential properties
• Property records for owners managing multiple units

For buyers and owners, measured plans are also helpful when room sizes or total area are unclear. If square footage is part of your decision-making, related guides such as how to verify square footage can help you think through the issue. Even when your immediate need is just a condo plan, accurate field documentation tends to make later decisions easier.

How to choose between DIY measuring and a professional service

It is possible to sketch and measure an apartment yourself, especially if the unit is small and your goal is casual space planning. But self-measured plans often run into problems. Angles get missed, wall thicknesses are inconsistent, fixtures are simplified too much, and the final file is not easy to hand off to an architect or contractor.

A professional service is usually the better fit when:

• You need dependable dimensions
• You want CAD files, not just a sketch
• The layout is irregular or has multiple corners and offsets
• The apartment has been remodeled over time
• Several people will rely on the drawing
• You may use the plan for permit or design work later

Professional measured drawings can also save time. Instead of spending hours taking notes, checking dimensions, and redrawing the layout, you get a finished apartment floor plan prepared from site measurements and drafted by senior professionals. For many owners and agents, that speed is the reason they order measured plans in the first place.

Frequently asked questions

Can you get a floor plan of an apartment if the building is old?

Yes. Older buildings are one of the most common reasons to order measured plans, because original drawings may be missing, incomplete, or outdated. If the current layout matters more than the historical plan, an on-site measurement is usually the most practical way to get a current unit floor plan.

Will a marketing flyer or old listing count as a condo plan?

It can be useful for basic orientation, but it is usually not enough if you need reliable dimensions or current conditions. Marketing plans are often simplified and may not reflect changes made over time. A measured apartment floor plan is the better choice when accuracy matters.

How fast can you get an apartment floor plan?

For FastAsBuilt 2D As-Built Plans, typical delivery is 48 to 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 to 5 business days, starting at $1,500, then $1.00 per square foot.

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

What files do you receive at the end?

FastAsBuilt provides permit-ready CAD files in PDF and DWG format. With the 3D option, you also receive a 3D model along with 2D floor plans, elevations, and sections. That makes it easier to share the apartment floor plan with agents, owners, architects, designers, and contractors.

Bottom line

If no reliable floor plan of an apartment exists, the clearest solution is to have the unit measured on site and drafted into current digital drawings. For California owners and property professionals, that means less guesswork, faster planning, and a plan you can actually use for listing, design, or the next step in your project.
