What Plans Do You Need for a Kitchen Remodel Permit?

If you are planning a kitchen remodel in California, one of the first questions is usually simple: what plans for kitchen remodel permit approval do you actually need? The short answer is that most building departments want a clear set of drawings showing the existing kitchen, the proposed new layout, and any changes to walls, windows, doors, electrical, plumbing, ventilation, and structure.

The exact submittal can vary by city, but the overall goal is consistent. Plan reviewers need enough information to understand what is there now, what you want to change, and whether the work can be approved for safety and code compliance. When your drawings are accurate, legible, and based on real field measurements, the permit process usually goes more smoothly.

Why kitchen permit drawings matter

A kitchen remodel often looks straightforward from the homeowner side, but permit reviewers see several systems at once. Cabinets may move, appliances may shift, lighting may be upgraded, circuits may be added, plumbing lines may be rerouted, and a soffit or wall may be opened. Even a “same footprint” remodel can trigger plan review when the scope affects electrical, plumbing, mechanical, or structure.

That is why kitchen plans are not just a formality. They help the city confirm:

• The layout is clear and fully dimensioned.
• Fixtures and appliances are identified.
• Electrical work is shown in a readable way.
• Plumbing changes are documented.
• Ventilation and exhaust are addressed where required.
• Any structural work is separated from cosmetic work.

In practice, the best remodel drawings also reduce confusion between owners, designers, contractors, and inspectors. Everyone works from the same information, which helps avoid costly revisions after permit comments come back.

Start with accurate existing conditions

Before you can prepare proposed kitchen plans, you need a reliable picture of the existing space. This is especially important in older California homes, where walls may not be square, prior work may not match old records, and the available plans may be incomplete or outdated.

Existing conditions drawings usually show the kitchen as it stands today, including wall lengths, door and window locations, ceiling changes, major fixtures, and the relationship to nearby rooms. If your remodel touches an exterior wall, adds or enlarges an opening, or changes circulation into adjacent areas, those existing measurements become even more important.

Many owners first ask whether they can permit a remodel without original plans. In some cases, yes—but you still need accurate measured drawings of the current house. If you are unsure what qualifies, this guide on whether you need existing plans to pull a permit explains the issue clearly.

FastAsBuilt handles this step by sending a local crew for on-site laser measurement and then having senior drafters prepare permit-ready CAD files in PDF and DWG format. For many remodel projects, that measured base drawing is what makes the rest of the permit set possible.

The core plans for kitchen remodel permit submittals

Most cities want a basic drawing set that can communicate the project without guesswork. For a kitchen remodel permit, the core sheets often include the following.

• Existing floor plan: the current kitchen and nearby spaces, measured and labeled.
• Proposed floor plan: the new layout with dimensions, cabinet runs, fixtures, appliances, and notes.
• Demolition plan: what will be removed, if the scope is not obvious from the other sheets.
• Electrical plan: lights, switches, outlets, appliance connections, and circuit-related notes.
• Plumbing plan: sink location, dishwasher, refrigerator water line if relevant, and any moved waste or supply lines.
• Elevations: vertical views of cabinet walls, backsplashes, appliances, windows, and height relationships.
• Sections or details: only where needed to clarify construction or structural changes.

Not every city asks for all of these in every case, and some simple jobs may be approved with a shorter set. But if you are trying to avoid resubmittals, it is smart to think in terms of clarity rather than minimum effort.

What should be shown on the floor plan

The floor plan is the heart of most kitchen remodel drawings. It should let a reviewer understand the room in one glance. A weak floor plan often leads to plan check comments because too much is left implied.

Existing plan expectations

The existing plan should identify walls, doors, windows, and the current location of major fixtures and appliances. It should also show enough of the surrounding area to explain access, openings, and the kitchen’s relationship to dining or living spaces.

Proposed plan expectations

The proposed plan should be more detailed. In most cases, it should show:

• Overall room dimensions and key wall dimensions.
• Cabinet layout and major casework.
• Sink, range, oven, cooktop, refrigerator, dishwasher, and hood location as applicable.
• Door and window sizes and locations.
• Any moved or removed walls.
• Notes identifying new versus existing work.

If the remodel changes only finishes and cabinets, that may be enough for the layout sheet. If you are removing a pantry wall, widening an opening, or affecting beams or posts, you will usually need more than a basic floor plan.

Homeowners sometimes try to sketch this from old listing photos or rough tape measurements, but permit sets are stronger when they start from measured as-builts. If you want to understand that process better, see how to get permit-ready as-built drawings.

Electrical, plumbing, and mechanical notes the city looks for

A kitchen remodel permit is often driven less by cabinets and more by the systems hidden behind them. Even when the footprint stays similar, reviewers want to know what happens to power, water, drainage, and ventilation.

Electrical plan

Your electrical sheet should clearly identify lighting, switches, receptacles, dedicated appliance connections, and any equipment that needs special coordination. The city may also expect load-related documentation depending on the scope, but the key point for the plan set is that the kitchen’s power layout is legible and complete.

Plumbing plan

If the sink, dishwasher, refrigerator line, or other fixtures move, the plumbing plan should show that change. Even a small relocation can affect rough-in work and inspection requirements. If everything stays in place, a note may still be helpful so the reviewer is not left guessing.

Mechanical and ventilation

Range hood or exhaust information may be part of the submittal, especially when ducting is added or changed. If the project affects exterior penetrations or soffits, that should be coordinated on the drawings.

For many permit applications, these systems can be shown on separate sheets or layered into the main kitchen plans. What matters most is that the permit reviewer can follow the scope cleanly.

When elevations, sections, or structural drawings are needed

Some kitchen remodel permit applications can be reviewed with floor plans and system notes alone. Others need additional views. The trigger is usually complexity, not room size.

You may need interior elevations when cabinet heights, window relationships, backsplashes, soffits, open shelving, or appliance walls need clarification. Elevations are especially useful when a plan reviewer cannot easily understand how the finished kitchen will stack vertically.

Sections or details can help when the project includes:

• A removed or altered wall.
• A widened opening between kitchen and living areas.
• A new beam, post, or header.
• Ceiling changes or dropped soffits.
• Built-in seating or custom casework that affects construction.

If the remodel includes structural work, your submittal may also require engineering or structural sheets prepared by the appropriate design professional. That scope goes beyond basic measured floor plans, but accurate existing documentation still supports the team doing the final permit set.

How detailed the drawings should be

One of the most common mistakes in remodel drawings is being too vague. Another is overloading a simple project with cluttered notes that do not help review. Good kitchen plans find the middle ground: enough detail to permit and build the project, without making the set hard to read.

As a rule, your remodel drawings should be:

• Measured: based on real field dimensions, not assumptions.
• Legible: room labels, fixture tags, and notes should be easy to read.
• Consistent: dimensions and notes should agree from sheet to sheet.
• Scoped correctly: demolition, existing work, and new work should be easy to distinguish.
• Specific: enough information should be included so the city does not need to infer the design.

If you are hiring a designer or contractor, ask early who is responsible for producing the permit set and whether they need measured existing plans first. Many delays happen when everyone assumes someone else is creating the base drawings.

Frequently asked questions

Do you always need existing plans for a kitchen remodel permit?

Not always original plans, but you usually need accurate existing-condition drawings. If the city cannot tell what is there now, it is harder to review what you want to change. Measured as-built plans are often the best substitute when old plans are missing or unreliable.

Can you get a permit with only cabinet drawings?

Usually not. Cabinet layouts may help explain the design, but most kitchen remodel permit applications also need a floor plan and enough electrical, plumbing, and scope information to show how the work affects the house. If walls, openings, or systems change, the city will want more than cabinetry alone.

Do simple kitchen remodels need elevations?

Sometimes no, sometimes yes. If the scope is very straightforward and the floor plan clearly communicates the work, elevations may not be necessary. But if cabinet heights, appliance walls, window alignments, soffits, or finish transitions are important to understanding the project, elevations can help avoid plan check comments.

How fast can measured plans be prepared before permit design starts?

That depends on the package and project size. FastAsBuilt’s 2D As-Built Plans typically deliver in 48–72 hours, while 3D As-Built Plans typically deliver in 3–5 business days. For many kitchen remodels, that timeline helps owners and design teams move into permit preparation quickly.

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

Bottom line

For most California projects, the plans for kitchen remodel permit approval should include accurate existing conditions, a clear proposed floor plan, and any electrical, plumbing, mechanical, elevation, or structural drawings needed to explain the scope. The more clearly your kitchen plans show what exists and what is changing, the better your chances of a smoother review. FastAsBuilt helps you start with measured, permit-ready base drawings so your remodel submittal has a solid foundation.
