How much do remodel drawings cost in California (2026)
If you are planning a kitchen, bathroom or interior remodel in California, the drawings are one of the first bills you see and one of the hardest to compare. One office quotes a flat fee, another quotes per square foot, a third quotes a percentage of construction. This guide sorts the common pricing models, shows the ranges providers publish, and explains what actually moves the number.
Updated 2026-10-10. Every price below is a published range we read on that date, not a quote for your house. Rules differ by city, so check with your own building department before you rely on any of it.
What "remodel drawings" usually means
A remodel set is not one document. Depending on the job, it can include:
- Existing conditions (as-built) plan. An accurate plan of the house as it stands today: walls, openings, fixtures, ceiling heights.
- Proposed floor plan. What changes: walls removed or added, fixtures moved, new doors and windows.
- Elevations and sections. Needed when the exterior changes or when the reviewer needs to see heights.
- Electrical, plumbing and mechanical notes. Often drawn on the floor plan for small jobs.
- Structural details or calculations. Only when you touch load paths, such as removing a bearing wall.
The more of that list your project needs, the higher the fee. A cosmetic bathroom refresh may need very little. Moving a kitchen wall needs most of it.
What California cities ask to see
Cities publish their own submittal lists, and they are worth reading before you buy anything. The City of San Diego's Information Bulletin 140 for residential additions and remodels lists a site plan, a floor plan that identifies "room uses, dimensions, windows, doors, plumbing fixtures, heating equipment, and exhaust fans", roof framing, elevations and connection details, and says plans must be "drawn to scale and be of sufficient clarity to indicate the location and extent of the proposed work" (San Diego IB 140, read 2026-10-10). Not every remodel triggers every sheet on that list, and your city may ask for less or more.
The practical point: the city sets the minimum, and the minimum is what you should price against first.
Who is allowed to draw them
You do not always need an architect. California Business and Professions Code section 5537 says the architecture licensing chapter does not prohibit any person from preparing plans for single-family dwellings of woodframe construction not more than two stories and basement in height. It also says the building official may require an engineer or architect for any portion that deviates from conventional light wood-frame construction (BPC 5537 on Justia, read 2026-10-10). Many cities restate this in their own handouts. In plain terms: a typical single-family interior remodel can often be drawn by a designer or drafter, while structural changes may still need a licensed engineer's calculations. This is general information, not legal advice; ask your building department how it applies to your address.

The three common pricing models
1. Per square foot
Drafting and measuring firms often price by floor area with a minimum fee. For as-built work, one California provider publishes a range of $0.50 to $3 per square foot (Design OTB California guide, read 2026-10-10). Another California guide lists residential projects "from $2,500" for a home under 2,000 sq ft and $2,500 to $4,000 for a 2,000 to 4,000 sq ft home, with a $2,500 minimum project fee and a 25 to 50 percent premium for rush delivery under 72 hours (LiDAR As-Built Drawings, California 2026 guide, read 2026-10-10). Those are existing-conditions figures. A full permit set with proposed changes usually costs more, because someone has to design the change and answer plan check comments.
2. Flat fee per project
Designers who do a lot of kitchens and bathrooms often quote a flat fee per room or per package. This is easy to budget, but read the scope line by line: how many revision rounds, whether plan check corrections are included, and whether measuring the house is part of it.
3. Percentage of construction
Full-service architects on larger jobs often quote a percentage of construction cost. That model makes sense when the architect is also managing design decisions, bidding and site visits. For a small interior remodel it can be more service than you need. We did not find a published California percentage range we would stand behind, so we are not quoting one here.
What drives the price up or down
- Measuring. If nobody has an accurate existing plan, someone has to visit and measure. That is often the biggest single line on small jobs. If you already have an accurate plan, say so up front.
- Scope of change. Moving plumbing walls, removing a wall or adding windows adds sheets and review time.
- Structural work. Engineer calculations are a separate fee in most quotes.
- City and plan check. Some cities return more comments than others. Ask whether responding to corrections is included or billed hourly.
- Turnaround. Rush delivery is commonly priced as a surcharge, as the LiDAR guide above shows.
- Format. A PDF permit set is one thing. CAD or BIM files you can hand to other trades may cost extra.
A simple way to estimate your own budget
- Measure the finished floor area of the rooms that change, not the whole house, unless the whole house is in scope.
- Write down what changes: walls, fixtures, windows, electrical.
- Ask each provider for a fixed price, the sheet list, the number of revision rounds and the turnaround, in writing.
- Compare quotes on the same sheet list, not on the headline number.
If you also want a material list for bidding, try our free takeoff calculator. It turns room dimensions into drywall, flooring and paint quantities you can price.
How RemodelSet prices it
We price builder sets by finished floor area with a minimum, quoted before you pay. At the time of writing our pilot price for the first 10 orders is $1.00 per sq ft with a $990 minimum, then a list price of $1.50 per sq ft with a $1,490 minimum. A builder set includes the plan and a material takeoff. Current prices and what each tier includes are on our pricing page. We do not stamp drawings; if your job needs an engineer or architect, we say so before you order. Our sample project shows the sheets and takeoff a builder set contains, on a made-up house.
Bottom line
For a California remodel in 2026, published drawing fees run from a few hundred dollars for a simple redraw to several thousand for a measured, permit-ready set, and providers price it per square foot, per project or as a percentage. The fastest way to a fair number is to know your city's sheet list, know your square footage, and ask every provider to quote the same scope.
