The short answer
An interior designer in San Diego charges $60 to $535 an hour, and one room runs $535 to $1,800 for design alone. California does not license interior designers. The title Certified Interior Designer is protected, and a wall change needs an architect or engineer.
What interior designers cost in San Diego
The ranges below apply the San Diego construction cost factor of 1.19 from the U.S. Army Corps of Engineers to national cost data. They cover design fees. Furniture is billed separately.
| Job | San Diego (typical range) | US average |
|---|---|---|
| Interior designer, per hour | $60–$535/hr | $50–$450/hr |
| In-home consultation | $60–$535 | $50–$450 |
| One room, design only | $535–$1,800 | $450–$1,500 |
| One room, design and furnishing | $1,200–$14,300 | $1,000–$12,000 |
| Whole home, per sq ft | $6–$20/sq ft | $5–$17/sq ft |
| Whole home, 2,000 sq ft | $11,900–$40,450 | $10,000–$34,000 |
Estimates for 2026, including labor and standard parts. San Diego prices use the metro's construction cost factor of 1.19 (US average = 1.00) from the U.S. Army Corps of Engineers Area Cost Factors. Your quote depends on access, materials and the condition of the home.
Fees depend on the size of the job, the designer's experience and how much buying the designer does for you. A firm principal bills near the top of the hourly range, a junior designer near the bottom. Whole-home work is usually quoted per square foot, and a 2,000 square foot house lands between $11,900 and $40,450 in design fees.
The cost estimator below asks about your rooms and scope and applies the rate for your ZIP code.
How San Diego designers bill
Most firms pick one fee structure and sometimes combine two on the same project, for example an hourly rate for the concept and a markup on the furniture. The common structures:
| Fee structure | How it works | Where it fits |
|---|---|---|
| Hourly | Time logged and billed | Consultations, small scopes, ongoing advice |
| Flat fee per room | A fixed price for a defined scope | One room, clear deliverables |
| Per square foot | A rate applied to the whole home | Whole-home work, large remodels |
| Percent of construction cost | A share of the build price | Remodels with construction |
| Cost plus | A markup added to product and trade costs | The designer buys and manages |
| Markup on retail | A markup on furnishings at retail price | Furniture and decor packages |
Charges that surprise people
A retainer is normally due at signing. Some firms ask for a share of the project up front. Product deposits are common when the designer orders furniture for you. A designer who manages trades during construction usually adds a management fee. Travel time is often billed, and it adds up when the designer drives from La Jolla to a job in El Cajon. CAD drawings are often billed separately.
Ask whether the markup is calculated before or after sales tax, and whether tax appears as its own line. San Diego County sales tax rates vary by city, so the rate on a Carlsbad purchase differs from one in Chula Vista. Get the number in writing before you place the first order.
California's rules for interior designers
California has no license requirement to practice interior design. Anyone can offer interior design or decorating services in the state.
The "Certified Interior Designer" title
California protects one title. The Business and Professions Code created the "Certified Interior Designer" (CID) title, administered by the California Council for Interior Design Certification (CCIDC), a nonprofit. Under section 5800, a CID prepares and submits nonstructural or nonseismic plans to local building departments, and those plans must be complex enough to require a licensed contractor to build them. A CID designs and documents nonstructural elements, finishes and furnishings inside a building.
Certification is voluntary. Plenty of working designers in San Diego do not hold it. If the answer is yes, ask for the certification number.
What a CID contract has to include
A Certified Interior Designer must sign a written contract with you before work starts. Ask any designer, certified or not, to put the services, the fee structure, the markup, the retainer and the deposit terms in writing. The list a CID works from is a good standard for any designer.
When you need an architect or engineer instead
The building's structure decides whether a designer's drawings are enough. If they are not, you need an architect. An unlicensed person may prepare plans for nonstructural or nonseismic storefronts, interior alterations or additions, fixtures, cabinetwork, furniture and equipment, according to city plan-preparer handouts that summarize the state rules. An unlicensed person may not prepare plans for alterations that change or affect any component of the structural system or the safety of the building or its occupants.
Section 5537 lets an unlicensed person draw a single-family wood-frame home of up to two stories plus a basement, and multiple dwellings of up to four units, but any part that departs from conventional framing must be designed and stamped by a licensed architect or registered engineer. Interior alterations with walls and partitions over 5 feet 9 inches in height, or ceiling work covering more than 3,000 square feet in certain commercial occupancies, also need stamped plans.
If your project removes a bearing wall, adds a beam, opens a large window in an exterior wall or adds square footage, bring in an architect or structural engineer. The structural coordination guide explains how the engineer fits in, and the residential design guide covers the drawing set. For a full set ready for the city, see permit drawings. If the project is an addition, the additions and remodels guide walks through the sequence, and an ADU has its own path in the ADU design guide.
Do you need a permit?
Interior design itself needs no permit. The work it leads to often does. Each city in the county runs its own building department. The answer depends on where the house is.
City of San Diego
A building permit is required to construct any new structure or to improve existing buildings. The city's Information Bulletin 203 lists work that needs no permit, including relocating cabinets and countertops in a kitchen of a single-family home, duplex or townhouse, and tub-to-tub or shower-to-shower replacements that keep the same size and location. Repairs that only replace components with similar materials, cost no more than $1,000 in aggregate valuation and do not touch electrical, plumbing or mechanical work also skip the permit. Permit-exempt work still has to meet the building codes.
You submit new permits and approvals online. Building permits expire 3 years after issuance for single-family homes and duplexes, and 4 years for other structures. A permit expires if work has not started within 1 year. After work starts, a valid inspection must be passed at least every 180 days. The city may require a Historical Review even for work that otherwise qualifies as a no-plan permit.
Chula Vista
A building permit is required when a project involves a new or changed use of the property, or work that physically changes or adds structures, even if the alteration is not visible from outside. Projects that need discretionary approvals such as Design Review must be approved before you apply for a building permit. Planning also reviews work in historical districts and buildings and proposed demolition of buildings older than 50 years. The city accepts and reviews plans electronically through Citizen Access. All fees must be paid by credit card. You pay an intake fee and full plan review fees before the city reviews the plans.
Carlsbad
Carlsbad generally requires a building permit when you add new structures or physically change existing structures. Kitchen or bathroom remodels generally trigger a permit. So do new or relocated lighting, water heaters or ceiling fans. Residential projects use the B-1 application form. For permits that require plan check, the city does not begin review until you pay the fees, and plan check lasts one year from submittal.
Oceanside
Starting January 2, 2025, all applications with plan submittals must go through the web-based process. The city no longer accepts paper plans. Projects that involve removing walls must show on a framing plan whether the walls are bearing walls. Unlicensed design professionals may only submit plans for up to 4 dwellings on one lot, of wood-frame construction, not more than two stories and a basement in height. Plan review expires two calendar years from submittal. You can get one six-month extension if you request it in writing before expiration.
Escondido
The Building Division accepts plans only in electronic format. Plan review takes about 30 calendar days for each review cycle once a complete set of construction documents is received. A permit is valid for 1 year after issuance and extended 180 days after inspection. You can get a 180-day extension with written approval. Because of the California Building Code update effective January 1, 2026, the city will not provide plan check extensions on applications submitted before that date.
El Cajon
The city's Project Assistance Center brings Planning, Engineering and Building services together. Applicants can use the online portal, PACO, to submit certain project types, pay for permits, schedule inspections and get status updates. Building staff can be reached at 619-441-1726.
Unincorporated San Diego County
Projects in the unincorporated areas go through County Planning & Development Services. The Building Division hotline is (858) 565-5920, and printed application forms can be brought to the County Permit Center.
For build costs once the design is set, see the San Diego kitchen remodeling guide and the bathroom remodeling guide.
How long design takes in San Diego
Schedules depend on the scope and on how fast you make decisions. A furnishing-only project skips the drawings and the city, so the wait is mostly furniture lead times. A project with wall changes adds drawing time, then plan review at the city. Escondido runs about 30 calendar days per review cycle. Chula Vista's goal for a residential addition or remodel is 15 business days for the first review.
| Project | What sets the pace |
|---|---|
| Furnish or restyle a room | Your decisions, then order and delivery times |
| Kitchen or bath, same layout | Selections, then the city permit |
| Kitchen or bath with wall changes | Floor plans, then plan check |
| Remodel touching structure | Architect and engineer drawings, then plan check |
Changes after drawings are finished cost the most time. Plans may need to go back through review. In San Diego, the city must review and approve all changes to approved plans during construction before they go into the construction documents.
How to check an interior designer before you hire
- Ask whether they are a Certified Interior Designer. If yes, ask for the certification number and confirm it with CCIDC.
- Look at completed San Diego County projects of a similar size and budget.
- Get the fee structure in writing, including any markup, retainer and deposit.
- Ask who draws anything structural and who pulls permits.
- Ask whether they carry errors and omissions insurance.
- Make sure the contract lists the number of revision rounds.
If a designer offers to build the project too, look up their contractor license on the CSLB site before you sign. California requires a CSLB license for nearly all construction work. Since January 1, 2025, the only exemption is minor work under $1,000 in labor and materials that needs no building permit and is done without employees. Projects over $500 need a written home improvement contract, and the down payment cannot exceed $1,000 or 10 percent of the contract price, whichever is less. For milestone payment practices, see how payment protection works.

What is a CID in California?
A Certified Interior Designer, certified by the California Council for Interior Design Certification under the Business and Professions Code. A CID can prepare and submit nonstructural or nonseismic plans to local building departments. Certification is voluntary, so many San Diego designers do not hold it.
Can an interior designer remove a wall in my San Diego home?
They can plan it. If the wall is load bearing, the structural part needs an architect or engineer. In Oceanside, projects that involve removing walls must show on a framing plan whether the walls are bearing walls. In San Diego, moving walls takes a building permit with plans.
Do I need a permit to redo my kitchen in San Diego?
It depends on the city and the scope. In the City of San Diego, relocating cabinets and countertops in a single-family home, duplex or townhouse needs no building permit. In Carlsbad, kitchen or bathroom remodels generally trigger a building permit. Adding circuits or moving plumbing needs a permit in San Diego.
How do San Diego designers charge for furniture?
Usually through cost plus, a markup added to product and trade costs, or a markup on retail furnishings. Product deposits are common. Ask how the markup is calculated and how sales tax is billed, since the rate varies by city in the county.
How long does an interior design project take in San Diego?
A furnishing-only project depends mostly on furniture lead times. A project with wall changes adds drawing time and plan review. Escondido takes about 30 calendar days per review cycle, and Chula Vista's goal for a residential addition or remodel is 15 business days for the first review.

How we calculate these prices
GOLDGCP starts from national price ranges for each job, taken from published 2026 cost guides and checked against local price guides where they exist. To get a local price, we multiply the national range by the construction cost factor for the metro from the U.S. Army Corps of Engineers Area Cost Factors (US average = 1.00). Where that table has no entry for a metro, we use the nearest listed location or the state value. For ZIP codes outside the 50 largest metros, the cost estimator uses the state's price level from the Bureau of Economic Analysis Regional Price Parities. Ranges include labor and standard materials but not unusual site conditions, so a written quote after an inspection is always the final price.
