Accessory Dwelling Units are more than just a fad in Studio City-these are maybe one of the best investments one could make. Whether you’re building for a family, planning to rent it out, or just to augment property value, there is one big question that comes into play: cost of building an ADU.
Let’s analyze the adjutants, underlying factors, and how a custom-made ADU builder like Katz Design Builders can make all the difference in Studio City.
What Is an ADU and Why Build One in Studio City?
An ADU, sometimes referred to as a granny flat or backyard cottage, is a secondary dwelling unit constructed on the same parcel of land as a single-family residence. Studio City residents are increasingly using ADUs for:
- Rental income
- Multi-generational householding
- Home offices or studio spaces
The city’s enlightened zoning laws and growing need for flexible housing make it a perfect location. But how expensive are custom ADU designs in Studio City here, and what influences those prices?
The Average Cost to Build an ADU: A Quick Overview
| Type of ADU | Average Cost Range (Studio City) |
| Detached New Construction | $275,000 – $450,000 |
| Attached ADU | $200,000 – $375,000 |
| Garage Conversion | $100,000 – $175,000 |
| Basement Conversion | $125,000 – $200,000 |

Breaking Down the Costs
- Design & Permitting
Before a single nail is driven, you’ll have spent $15,000 to $30,000 on design, architectural plans, engineering, and permits. A bespoke ADU design in Studio City involves adhering to strict local codes while still designing a space that reflects your vision.
Pro Tip: Work with a design-build firm like Katz to avoid expensive reworks due to code changes.
- Site Preparation
Site work can really impact your profit margin. Generally, demolition, grading, tree removal, and utility access can go anywhere from $10,000 to $40,000 in complexity.
- Construction Cost
The construction is made out of the framing, roofing, plumbing, electrical, HVAC, insulation, and finishes.
-
- Generic Construction: $250 – $400 per sq. ft.
- Luxury finishes: more than $500 per sq. ft.
For example, a 600 sq. ft. detached ADU with mid-level finishes may cost from $210,000 to $270,000 for the building alone.
- Utilities & System Upgrades
If the utilities of your primary residence cannot cope with the added load, anticipate extra fees:
-
- Sewer connection: $4,000 – $12,000
- Electrical upgrades: $3,000 – $10,000
- Meters separate: Optional but can be up to $5,000
- Project Management & Labor
Labor costs in Studio City tend to be higher. Skilled labor (licensed electricians, plumbers, etc.) and project management might take up 30% to 40% of your overall project cost.
What Factors Impact the Final Cost?
1. Type of ADU
Functions as the screening for an existing garage conversion instead of an addition: with less expense. Otherwise, more design hours will be accounted for in a foundation build.
2. Size & Layout
More square footage means more materials, labor, and time, but in rental potential, more square footage counts.
3. Site Conditions
Uneven ground, poor soil, or restricted access can drive site prep and foundation costs through the roof.
4. Material & Finish Choices
Are you opting for plain vinyl flooring or radiant heat with polished concrete? Finishes tend to balance your ultimate price by tens of thousands.
5. Contractor Experience
Working with a custom ADU builder in Studio City such as Katz Design Builders guarantees easier permitting, trustworthy workmanship, and reduced change orders.

Final Thoughts: What Will Your ADU Cost?
