How to Get a Site Plan for Your Property

If you are asking how to get a site plan for my property, you are usually trying to move a project forward: a lease, permit, renovation, tenant improvement, expansion, or due diligence before design. In California, the right starting document depends on what you need to show. Some projects only need a basic site plan assembled from existing records and field-verified building information. Others require a plot plan based on parcel data, and some need a formal property survey prepared by a licensed land surveyor.

The confusion is common because people use “site plan,” “plot plan,” and “property survey” as if they mean the same thing. They do not. A site plan is typically a drawing that shows the building and site improvements in relation to the lot. A plot plan often focuses on lot lines, dimensions, setbacks, and the building footprint. A property survey establishes or confirms boundary information in the field. Knowing the difference helps you avoid ordering the wrong deliverable, paying for work you do not need, or submitting plans that a city reviewer rejects.

What a site plan for your property usually includes

A site plan is a scaled drawing of the property as it exists or as it is proposed to be improved. For commercial uses, it helps owners, tenants, architects, contractors, and plan reviewers understand how the building sits on the lot and how the site functions.

Depending on the purpose, a site plan may show:

• Property lines and lot dimensions
• Building footprint and overall exterior dimensions
• Setbacks from structures to property lines
• Driveways, access points, parking areas, and walkways
• Fences, walls, gates, and loading areas
• Landscape areas, paved areas, and open space
• Detached structures and site features
• North arrow, scale, address, and parcel information

For permit work, the city may also want square footage, occupancy-related notes, or references to architectural sheets. If your project includes an existing building, accurate existing conditions matter. That is where measured drawings can support the process. If you need the interior documented too, as-built drawings provide a clear record of what is actually on site.

Site plan vs. plot plan vs. property survey

Before you order anything, match the document to the decision you need to make.

Site plan

A site plan is the most general term. It is often used for permit sets, planning reviews, leasing exhibits, and renovation planning. It may combine information from county records, prior plans, field measurements, and design input. A site plan can be existing, proposed, or both.

Plot plan

A plot plan is usually narrower in scope. It often emphasizes the parcel boundary, lot dimensions, easements if known, setbacks, and the building footprint on the lot. Some jurisdictions and contractors use “plot plan” when they really mean a simple site plan, so always check the city checklist.

Property survey

A property survey is different because it is boundary work. If your project depends on exact legal boundaries, encroachments, or establishing corners on the ground, you may need a licensed land surveyor. Measured building drawings alone do not replace a survey, and a city may reject a submittal if boundary information must be survey-based.

In practical terms, many commercial property owners need two separate things: a survey for boundary certainty and measured as-built drawings for the existing building. If you are planning permit work, it also helps to understand how as-built drawings support permit applications.

When you need a site plan in California

A site plan is often requested whenever a project affects the use of land, access, building area, or exterior improvements. In commercial settings, common situations include:

• Tenant improvements where the city wants to see the suite within the larger property context
• Exterior alterations such as doors, ramps, patios, trash enclosures, or equipment pads
• Parking reconfiguration, striping changes, or accessible path adjustments
• Change-of-use reviews or planning submittals
• Pre-lease due diligence for a new tenant
• Feasibility studies before design begins
• Property marketing or transaction support

California cities do not all ask for the same level of detail. A small storefront update in one city may only need a simple existing site plan with dimensions, while another jurisdiction may ask for more complete parcel and code-related information. That is why the fastest route is usually to pull the planning or building department checklist first, then match your drawing package to it.

If your team is still gathering existing conditions, measured plans are often the first step. FastAsBuilt provides field-measured as-built drawings and measured floor plans across California, with local crews serving Southern California, the Bay Area, and San Diego. We use on-site laser measurement, then senior drafters produce permit-ready CAD files in PDF and DWG formats.

How to get a site plan for your property: the practical process

If your goal is to get a usable site plan without delay, work through the process in the right order.

1. Define the purpose

Ask what the drawing will be used for: permit, leasing, renovation planning, construction pricing, ownership records, or marketing. The answer determines the level of accuracy and who needs to prepare which parts.

2. Check city or landlord requirements

Look for required sheet content, scale, parcel information, and whether boundary dimensions must come from a survey. For commercial spaces, landlords may also have exhibit standards or rules for tenant plan submittals.

3. Gather what already exists

Useful source material may include prior permit plans, assessor records, title documents, older site plans, civil drawings, leasing plans, or survey documents. Even if they are outdated, they can reduce guesswork and help the drafter see what needs field verification.

4. Identify what must be measured on site

If the building, suite, or improvements need to be documented as they exist today, schedule field measurements. FastAsBuilt’s measured existing-condition plans are built from on-site laser measurement, which helps create reliable CAD backgrounds for design and permitting.

5. Decide whether you also need a survey

If your project depends on exact lot lines, legal boundary confirmation, or encroachment issues, engage a licensed surveyor. A measured floor plan or building footprint drawing is not a substitute for boundary work.

6. Have the information drafted into the right format

For many commercial projects, the final package needs clean CAD files that an architect, engineer, or permit expediter can continue working in. FastAsBuilt delivers PDF and DWG files so your project team can build on a practical base set rather than redraw from scratch.

If you need measured plans first, you can review how as-built drawings are made or place a request through our online order page.

What information you may need to provide

The more complete your starting information, the smoother the process tends to be. When requesting a site plan or measured existing-condition package, be ready to provide:

• Property address and suite number
• Project type and intended use of the drawing
• Approximate building or suite square footage
• Any prior plans, surveys, or landlord exhibits you have
• Photos of the exterior, parking, and access points if available
• Known concerns such as additions, missing records, or disputed dimensions
• Your deadline and required file formats

For commercial clients, it also helps to note whether the work involves one suite, an entire building, or a multi-tenant property. A site plan for a single storefront can be very different from one for a retail center, industrial site, or office campus.

Where measured as-built drawings fit in

Many people searching for a site plan for my property actually need a combination of documents. The site plan handles the lot and exterior relationship. The as-built package handles the building itself: floor plans, key dimensions, and sometimes elevations and sections.

FastAsBuilt offers two standard measured drawing options in California:

• 2D As-Built Plans starting at $900 for up to 1,500 square feet, then $0.50 per square foot; includes 1 revision and typical 48–72 hour delivery 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; includes a 3D model plus 2D floor plans, elevations, and sections, 2 revisions, with typical 3–5 business day delivery

Custom projects such as commercial properties, tenant improvements, ADUs, and SB9 work are quoted individually. If you are comparing options, this guide to California as-built drawing costs can help you understand the typical scope and pricing structure.

For a commercial remodel or lease turnover, these measured files can save time because architects and contractors are not forced to start from rough hand sketches or outdated PDFs. Instead, they receive a CAD base based on field measurement.

Common mistakes that slow down approvals

Projects often stall not because the site plan is impossible to produce, but because the wrong assumptions were made early.

• Using “site plan” as a catch-all term without confirming what the city actually requires
• Submitting an old leasing plan that does not reflect current conditions
• Assuming assessor data is accurate enough for design or permitting
• Skipping field verification of the building footprint or exterior access features
• Ordering measured drawings when a survey is the real requirement
• Ordering a survey when the actual need is a fast existing-conditions CAD background
• Failing to collect prior plans, which could have reduced time and rework

The safest approach is to separate building measurement from boundary determination. Building dimensions and existing layouts can be documented through measured as-built work. Legal lot boundaries and corner establishment belong with a surveyor when required.

How to choose the right provider

For a commercial project, the right provider is the one that matches the drawing to the task. If you need exact boundaries, hire a licensed surveyor. If you need the existing building and suite measured accurately for design, budgeting, or permit drafting, hire a measured drawing specialist.

When evaluating a provider for existing-condition documentation, look for:

• On-site measurement rather than guesswork from photos alone
• Clean CAD output in PDF and DWG formats
• Experience serving California projects and permit workflows
• Clear revision terms and realistic turnaround times
• A scope that distinguishes 2D plans from 3D models and expanded deliverables

FastAsBuilt focuses on field-measured as-built drawings and measured floor plans across California. Local crews serve Los Angeles, Orange County, the Inland Empire, the Bay Area, and San Diego. That regional coverage can be especially useful when a commercial portfolio includes multiple sites or when a local measurement visit is needed quickly.

Frequently asked questions

Can a site plan be made without a property survey?

Yes, in some cases. A site plan can be assembled from existing records, prior drawings, and field-verified building information if that meets the project need. But if exact legal boundaries, corner locations, encroachments, or survey-certified dimensions are required, you will likely need a licensed property surveyor.

What is the difference between a site plan and floor plans?

A site plan shows the property and how improvements sit on the lot. Floor plans show the interior layout of the building or suite. Many commercial projects need both: a site plan for the parcel context and measured floor plans for the actual space being renovated, leased, or permitted.

How fast can measured existing-condition plans be delivered?

For standard residential-sized 2D as-built plans, FastAsBuilt’s typical delivery is 48–72 hours, and 3D as-built plans are typically delivered in 3–5 business days. Commercial projects and custom scopes are quoted individually because the complexity, access, and required deliverables can vary widely.

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

Will city reviewers accept measured as-built drawings for permit work?

They are commonly used as the existing-condition basis for permit-ready drafting, especially when accurate current building dimensions are needed. However, acceptance depends on the city’s requirements and the type of project. If the jurisdiction requires boundary information from a survey, measured building drawings do not replace that survey requirement.

Bottom line

If you need a site plan for your property, start by identifying whether you need a general site plan, a plot plan focused on lot dimensions, or a formal property survey. For many California commercial projects, the most efficient path is a combination of reliable existing-condition measurement and the right boundary information for the jurisdiction. FastAsBuilt helps fill the building-measurement side of that process with field-measured, permit-ready CAD drawings that your project team can use right away.
