Permit Site Plan Drafting

Permit Site Plans in California for Residential and Commercial Projects

A permit site plan should do more than place a few boxes on a parcel. It should clearly communicate the existing property, the proposed work, critical dimensions, access, setbacks, and other site information that helps a reviewer understand how the project fits on the lot. SitePlan California prepares professional permit site plan drawings for homeowners, contractors, builders, developers, architects, permit expediters, real-estate professionals, and property managers throughout California.

Whether you are planning an ADU, home addition, garage, pool, deck, accessory structure, commercial improvement, demolition project, or another property change, we can review the available information and prepare a project-specific site plan rather than forcing every job into the same generic template.

Service Overview

A Scaled Property Drawing That Explains the Site Clearly

A permit site plan is a plan-view drawing of the property that shows how buildings, structures, improvements, access areas, and relevant site features relate to the lot. The exact information requested depends on the local jurisdiction and the type of permit. In California, there is no single universal checklist that every city and county uses for every project. A small patio cover may require a different level of detail than a new detached ADU, a commercial addition, or grading work on a sloped property.

What remains consistent is the need for clarity. A reviewer should be able to identify the property, understand what exists today, see what is proposed, and locate the work in relation to property lines and other important site conditions. That is why a good site plan is more than an aerial image or rough sketch. It is an organized drawing that brings together the available property records, survey information when available, client measurements, existing drawings, photographs, project dimensions, and known permit requirements.

What the Plan May Include

The Details Reviewers and Project Teams Need to Understand the Property

The elements below are commonly shown on permit site plans, but they are not automatically required on every project. We select and organize the information according to the project scope, available documentation, and known jurisdiction requirements.

01
Property Boundaries

Property Boundaries

The elements below are commonly shown on permit site plans, but they are not automatically required on every project. We select and organize the information according to the project scope, available documentation, and known jurisdiction requirements.

02
Existing Structures

Existing Structures

Lot lines and parcel dimensions can be shown from appropriate source information. Where verified boundary location is critical, a licensed survey may be required rather than relying on drafting assumptions.

03
Proposed Work

Proposed Work

The house, garage, accessory buildings, commercial structures, sheds, and other relevant improvements can be identified so the reviewer understands the current property layout.

04
Setbacks & Dimensions

Setbacks & Dimensions

New additions, ADUs, pools, decks, garages, patios, demolition areas, or other improvements are clearly distinguished from the existing condition.

05
Access & Circulation

Access & Circulation

Relevant distances between proposed work, existing structures, and property lines can be shown where the necessary project and property information is available.

06
Easements & Utilities

Easements & Utilities

Driveways, walkways, gates, parking areas, loading areas, or other circulation features may be shown when they affect the project or are requested for review.

That is why a good site plan is more than an aerial image or rough sketch. It is an organized drawing that brings together the available property records, survey information when available, client measurements, existing drawings, photographs, project dimensions, and known permit requirements.

Official guidance illustrates the level of information jurisdictions can expect. Los Angeles City Planning publishes plot-plan instructions and states that additional information may be required depending on the case. The City of San Diego explains that construction-permit site plans may need to show property lines, lot lines, easements, rights-of-way, buildings, and structures on the parcel. The practical lesson is simple: the drawing should be tailored to the property and the reviewing department, not copied from an unrelated project.

Drafting Support for Homeowners and Professional Project Teams

Existing and proposed coverage information may be included when it is part of the permit scope and sufficient dimensions are available for the calculation.

Plans are organized so orientation, scale, key dimensions, labels, and drawing notes are easy to read and useful to the broader permit package.

Site-specific notes can help explain the proposed work, clarify what remains unchanged, and coordinate the site plan with other drawings in the project set.

A site plan can look visually polished and still create problems during review if the drawing does not answer the reviewer’s basic questions. Common issues include missing dimensions, inconsistent property information, unlabeled existing versus proposed work, incomplete setback information, unclear access, or a drawing that was copied from a standard template without being adapted to the actual parcel.

Common Questions About California Permit Site Plans

SitePlan California provides site-plan and drafting services. Some projects require a licensed architect, professional engineer, civil engineer, land surveyor, geotechnical consultant, energy consultant, or other licensed professional. A drafting service does not replace those professional requirements when a jurisdiction or project scope requires them.

Provide the property address, proposed work, and any survey, existing plans, measurements, photographs, sketches, or permit comments you already have.

We review the available source information and identify what can reasonably be drafted, what details are missing, and whether separate professional information may be needed.

The existing property and proposed work are organized into a clear plan with the applicable dimensions, labels, notes, and project-specific site information.

Frequently Asked Questions

Send the Property Address and Tell Us What You’re Planning

Common questions about scope, source information, professional coordination, revisions, and delivery.

What information do you need to start a permit site plan?
Start with the property address and a clear description of the proposed work. Helpful supporting information can include a survey, existing plans, assessor or parcel information, property photos, client measurements, project sketches, permit correction comments, and dimensions of the proposed improvement. You do not need every document before making contact; we can review what you have and identify what is still needed.
Do I need a land survey for my permit site plan?
Not every project starts with a survey, but some projects or jurisdictions require verified boundary, elevation, topographic, or easement information. If the exact location of a property line is critical to the permit decision, general drafting should not be treated as a replacement for a licensed land survey.
Can you prepare a permit site plan anywhere in California?
Yes. SitePlan California provides remote drafting support for residential and commercial properties throughout California. The actual permit requirements are determined by the local reviewing jurisdiction, so the scope is adjusted to the project and the information available.
Can you prepare site plans for ADUs, additions, pools, and garages?
Yes. Those are common permit site plan projects. We also support decks, patios, accessory structures, demolition work, commercial property changes, existing-condition documentation, and other site-related drafting needs.
Can you revise the site plan after permit comments?
Applicable drafting-related correction comments can be reviewed and incorporated within the agreed project scope. Comments requiring licensed engineering, architecture, surveying, geotechnical work, or another specialty service remain separate professional requirements.
What file formats can you provide?
PDF is the standard final format for many site-plan projects. CAD or DWG source files can be provided when they are included in the agreed scope and are appropriate for the project workflow.
How accurate is a site plan created from online property information?
The drawing can only be as reliable as the source information used to create it. Assessor records, aerial imagery, client measurements, existing plans, and GIS information can be helpful references, but they should not be represented as a professional boundary or topographic survey when verified field information is required.
Do you guarantee permit approval?
No responsible drafting provider can guarantee approval because the reviewing authority controls the permit decision and may request additional documentation based on zoning, building, fire, engineering, planning, or other project-specific requirements. Our role is to provide clear site-plan drafting and revision support within the agreed scope.
