Site Plan Services Across San Diego County
Permit-Focused Site Plans for Property Projects
San Diego County site-plan and permit drawing support for unincorporated communities, from hillside ADUs and garage projects to graded lots, access roads and commercial improvements. The first step is verifying the County's jurisdiction over the address.
The County's Planning & Development Services (PDS) serves the unincorporated portion of San Diego County and provides Building, zoning, land-use, environmental and code-compliance services. Incorporated cities operate their own permit pathways.

Why Property Owners Use SitePlan California
A useful site-plan partner should make the property scope easier to understand before drafting begins. Our workflow is built around clear source information, permit coordination, editable local context, and a direct path from project idea to a reviewed drawing scope.
Permit-Focused Drafting
The drawing is organized around the property, proposed work, and permit coordination instead of decorative plan graphics.
Statewide California Coverage
The workflow supports projects throughout California while keeping local reviewing requirements separate and editable.
Correction-Ready Workflow
Written site-plan comments can be reviewed and incorporated when they fall within the agreed drafting scope.
Clear Professional Boundaries
Drafting is not misrepresented as surveying, engineering, architecture, or another licensed professional service when those disciplines are required.
How Site Plan Drafting Supports Projects Across San Diego County
A site plan is a scaled, top-down drawing that explains the relationship between a property and the work being proposed on it. Unlike a floor plan, which focuses on interior rooms, or an elevation, which explains vertical appearance, a site plan helps show where the project sits on the lot and how it relates to existing buildings, access areas, property information, and other relevant improvements.
That property-level context is why site plans appear in so many different permit workflows. A homeowner may need one for an accessory dwelling unit, pool, detached garage, deck, patio cover, home addition, demolition project, or other exterior improvement. A contractor may need a cleaner property base so architectural, structural, and site information do not contradict one another. A commercial owner may need to explain changes to parking, circulation, access, loading, exterior equipment, or the relationship between multiple structures.
For a project in San Diego County, the exact submittal requirements depend on the reviewing authority, the property, and the project type. A useful local page should therefore explain the drafting service while leaving room for verified local information rather than pretending one generic permit checklist applies everywhere.
Our approach is to build the property base first. Existing conditions and proposed work are separated visually so a reviewer does not have to guess what is changing. Relevant structures, access areas, dimensions, and documented property information are then coordinated into the drawing according to the project scope.
What Your Site Plan May Include
The exact contents depend on the property, project type, source documents, and reviewing agency. The items below are common site-plan components when they are relevant and supported by the available information.
Property Information
Available parcel information, lot dimensions, orientation, scale, and the base property context appropriate to the source records.
Existing Structures
Homes, garages, ADUs, sheds, pools, decks, covers, commercial buildings, and other relevant improvements already on site.
Proposed Improvement
The project footprint and location of the new work, clearly separated from the existing property conditions.
Distances & Setbacks
Relevant relationships to property limits or nearby structures when those distances are supported and needed for review.
Access & Circulation
Driveways, walkways, parking, gates, stairs, and other access areas when they matter to the project.
Easements & Utilities
Documented easement or utility information can be coordinated when supplied and relevant to the site-plan scope.
Existing vs. Proposed Logic
Clear graphic separation of what stays, what changes, and what is being removed or added.
Permit Notes & Labels
Scale, north arrow, dimensions, correction references, notes, and other project-specific site information.

Explore service →Permit & Property Planning in San Diego County
San Diego County Planning & Development Services states that it supports safe development in the unincorporated County and offers building permits, zoning research, code compliance, community planning and environmental review. A property in a community such as Ramona, Fallbrook, Valley Center or Alpine can have a different permit office from a nearby incorporated city. Confirm the address and the responsible jurisdiction before finalizing a title block or selecting permit forms. For a rural residence with a proposed addition, start with accurate property lines, the current house and accessory structures, driveway and access areas, the proposed new footprint and service features supported by survey or other reliable source materials.
Projects in unincorporated San Diego County may need site information for grading, drainage, fire access, wastewater or well/septic coordination depending on parcel and project type. The County PDS Online Services pages provide permit applications, payments, property research and appointment resources. A small urban garage conversion is not the same as a new dwelling on sloping rural land; the former may involve existing floor and service documentation while the latter may need grading or environmental supporting reports. Do not assume a permitted building envelope from the size of an assessor's map or a generic county setback table.
Building & Planning Coordination
Before submitting to PDS, distinguish Building review from land-use or environmental approvals and from outside utility or public works agencies. A County correction requesting fire access dimensions, an approved driveway approach or changed site grades should be answered in the actual affected drawing set. Use consistent addresses, assessor parcel references, elevations and drawing issue dates across consultant plans. Where the relevant requirements or reviewer comments call for structural or civil engineering, route those documents to a qualified licensed professional; a site-plan drafting service does not make an engineering stamp automatic.
ADU & JADU Property Context
For an unincorporated San Diego County ADU, identify whether the project is a new detached unit or a conversion of an existing building. Draw the principal residence, utility paths, access and adjacent site features with measured boundary offsets. On remote parcels, the sewage disposal approach or water service can be a central feasibility issue; confirm any septic or well conditions with the proper authority. State ADU rules may be relevant but the local PDS requirements and project-specific site conditions determine what supporting documentation must be submitted.
Property Conditions Can Change the Scope
San Diego County unincorporated territory includes inland valleys, mountain communities, agricultural parcels, fire-exposed access corridors and changing terrain. A county site plan may need a long access driveway, adjacent slope condition, septic disposal field or retaining feature documented, where the same elements would be less significant on an ordinary flat city lot. If no topo survey is provided, we flag the missing elevations and do not invent grading slopes. Fire and environmental constraints belong in the proper supporting reports rather than generic template notes.
California Map + Regional Site Plan Context
The map provides regional context for the current service area. The sketches illustrate common site-plan relationships such as existing conditions, proposed work, and drawing legends; they are explanatory examples rather than completed client projects.
Existing + Proposed Relationship
The drawing should make the current property and the new permit scope easy to distinguish.
Clear Permit Drawing Legend
Consistent graphic logic helps the reviewer trace what stays, what changes, and what is removed.
Property Projects We Support Across San Diego County
Illustrative County project: a proposed detached ADU on a rural parcel near Ramona. The drawing package starts with the actual parcel boundary record, existing residence, detached structures, access drive, proposed ADU location, utilities and any septic or water features. PDS determines which building and land-use application is required. If new grading is needed, a separate civil design may coordinate elevations and drainage with the architectural and structural documents.
Residential permit improvements
Site plans for additions, accessory structures, exterior improvements, and other residential work that changes how the property is used or built.
ADU and JADU projects
Property plans that coordinate the proposed unit with the main residence, garage, access, parking, and other existing improvements.
Pools, spas, decks, and patios
Backyard site plans that show the proposed improvement in relation to structures, property information, equipment areas, and access where relevant.
Garages and home additions
Plans for projects that add or change building footprint and therefore need stronger coordination with the existing lot.
Commercial property changes
Site-plan support for access, circulation, parking, exterior improvements, additions, and multi-building property conditions.
Corrections and existing conditions
Site-plan revisions, permit-response drafting, and as-built property bases prepared from the available project information.
How a County-Wide Site Plan Project Moves Forward
The process starts with the address and available project information, then moves through property-base drafting, proposed-work coordination, client review, and applicable revisions.
Send the Property Address
Send the property address, project type, and a short description of the work. Tell us if the project is new or already in plan review.
Upload Existing Information
Upload any survey, prior site plan, contractor sketch, architectural drawing, measurements, property photos, or written permit comments you already have.
Review the Property & Scope
We review the available information, identify the likely site-plan scope, and flag where additional verified information or another professional discipline may be needed.
Build the CAD Property Base
The existing property is organized into a consistent CAD base before the proposed improvement is added.
Add the Proposed Work
The proposed work is added with the relevant dimensions, relationships, notes, and labels included in the agreed drafting scope.
Client Review + Final Files
You review the draft against the actual project information. Applicable drafting revisions are completed before the final files are issued.
Common Site Plan Problems We Check Before Final Delivery
Many avoidable corrections happen when the property, proposed work, dimensions, or related permit drawings do not agree with one another.
Our drafting review focuses on the source information used, existing-versus-proposed clarity, important property relationships, and coordination with the drawings or comments supplied by the project team.
Existing and proposed work blend together
Existing conditions and proposed work should be visually distinct so the permit scope is immediately understandable.
Critical dimensions are incomplete
Relevant property relationships, structure distances, or project dimensions should be shown consistently when they are part of the required scope.
The property base is incomplete
Important existing structures or improvements can affect the proposed work and should not be omitted when they are relevant.
Different sheets show different project information
The site plan should remain consistent with architectural drawings, contractor dimensions, and other project information supplied for the permit set.
Approximate information is presented as exact
GIS, aerial, assessor, owner, or contractor information should be described accurately and not presented as a licensed survey.
Local review comments were overlooked
Written plan-check comments should be reviewed carefully when they request changes to the site-plan information or coordination.
Site Plan Drafting vs. Land Surveying
A professional CAD drawing can look precise even when some source information came from prior plans, public records, GIS, aerial imagery, owner measurements, or contractor dimensions. That is why the source of the information matters.
A site plan helps organize property and project information. It is not automatically the same as a licensed land survey. When exact boundaries, topography, easements, monuments, or other field-verified conditions control the project, a licensed surveyor or another appropriate professional may be required.
Structural design, engineering calculations, architecture, geotechnical work, and other licensed responsibilities also remain separate when required. Clear scope language protects the property owner and helps keep the permit documentation professionally accurate.
Property + Project Coordination
Organizes available property and project information into a clear CAD drawing for permit coordination and documentation within the agreed scope.
Field-Verified Property Information
Professionally establishes or verifies boundaries, topography, easements, monuments, and other survey information when those services are required.
Site Plan FAQs for San Diego County, California
These answers explain our drafting process and common project questions. Current permit requirements should still be confirmed with the applicable reviewing agency for the property.
Do you provide site plan drafting throughout San Diego County?
Yes. SitePlan California provides remote site-plan drafting support for property projects across San Diego County. The reviewing authority can differ between incorporated cities and unincorporated county areas, so the property address is used to confirm the appropriate permit context.
Who reviews permits in San Diego County?
County of San Diego Planning & Development Services may be relevant for some projects, while incorporated cities within the county can have their own building and planning departments. The property address should be checked before relying on a county-wide permit assumption.
What should I send when requesting a site plan quote?
Start with the property address and a short description of the proposed work. If available, also send a survey, prior site plan, contractor sketch, architectural drawings, property photos, measurements, and any written permit correction comments.
Do I need a land survey before contacting you?
Not necessarily. We can review the property and available documents first. Exact legal boundaries, easements, topography, or other field-verified conditions may still require a licensed surveyor when those conditions control the project.
Can you help with permit correction comments?
Yes. Send the complete written correction notice. We can review the comments that relate to the site plan and address drafting items that fall within the agreed scope.
Can one site plan show more than one improvement?
Often, yes. A coordinated property base can be useful when a project includes related work such as an ADU, garage, pool, deck, patio cover, addition, or demolition area. The final drawing scope depends on the permit package and project information.
Does a site plan guarantee permit approval?
No. Permit approval is controlled by the reviewing agency. Our role is to prepare clear site-plan drafting and applicable revisions within the agreed scope.
Do you work with contractors, architects, and permit expediters?
Yes. We work with homeowners, contractors, builders, developers, architects, permit expediters, property managers, and other project professionals who need a clear property-level CAD site plan.
