You do not have to look far for ADU plans & permits in Mar Vista. We regularly guide projects across Los Angeles, and the contractors in our network plan the build around your schedule. We are also active in Venice, Palms, Del Rey and West Los Angeles.
Mar Vista is classic postwar Westside: block after block of 1940s and 1950s ranch homes and minimal traditional houses on flat, rectangular lots. The typical setup is a long driveway leading to a detached one- or two-car garage at the back of the lot, and that layout is close to ideal for an ADU. The garage can be converted into a legal unit, or replaced with a new-build ADU if you want more square footage, while the main house stays untouched. Families here use ADUs for aging parents, adult kids and rental income, helped by Mar Vista's location between Venice, Culver City and the Expo Line. Because the lots are level and the garages are structurally straightforward, projects in Mar Vista tend to run smoothly through LADBS review. Think of postwar ranch homes, 1940s minimal traditional houses, mid-century family homes and remodeled contemporary homes: we tailor the approach to the type of home and the condition of your lot and existing structures.
Before a single wall goes up, every ADU in Los Angeles needs an approved set of plans and a building permit from LADBS, the Los Angeles Department of Building and Safety. That means architectural drawings, structural calculations, a Title 24 energy report and a plan check review by the city. For most homeowners, this paper phase is the most confusing part of the whole project. It is also where projects stall.
Every property is different. That is why we always start with a free conversation about your lot, your goals and your budget range. You do not need to know exactly what you want yet: during that conversation we go over the options, the approach and the cost factors.

ADU Plans & Permits in Mar Vista: what is possible
Free feasibility check
We review your lot before you commit: zoning, lot size, existing structures, setbacks, utilities and access. You get a straight answer on what kind of ADU your property supports and what the path to a permit looks like.
Site measurement and as-built drawings
Your design team measures your property and existing structures and draws them up as they stand today. Accurate as-builts are the foundation of a clean plan set, especially for garage conversions where the existing structure carries the design.
ADU design and floor plan
A licensed architect designs the layout around how the unit will actually be used: rental, family member or home office. You review the floor plan and elevations and approve the design before anything goes to the city.
Permit-ready architectural drawings
The full plan set LADBS requires: site plan, floor plans, elevations, sections, construction details and code notes. Drawn to city standards so the plan checker can review it without guesswork.
Structural engineering and calculations
A licensed structural engineer calculates foundations, framing and seismic loads and produces the structural sheets and calculations LADBS requires. For garage conversions this covers new openings, infilled garage doors and any strengthening of the existing structure.
Title 24 energy calculations
Title 24 is California's building energy code. Your design team produces the required energy compliance report covering insulation, windows, heating, cooling and water heating, matched to the products the project will actually use.
LA ADU Standard Plan Program guidance
LADBS maintains a list of pre-approved ADU standard plans. Because the design itself is already reviewed, plan check focuses on site-specific items, which can save time. We advise honestly on whether a standard plan or a custom design fits your lot and goals better.
LADBS plan check submission
Your design team prepares and submits the complete application through the city's online system, including all required forms and clearances. We coordinate the package and check it for completeness, because a complete, well-organized submission is the single biggest factor in a fast review.
Plan check corrections handled
Almost every application gets a corrections list from the plan checker. Your design team responds to each comment, revises the drawings and resubmits until the set is approved. We track every round and translate the city's comments into plain English, so you always know where your application stands.
You can find the full overview on our ADU plans & permits page.
Why invest in ADU plans & permits?
Most homeowners who call us are not short on motivation. They are stuck on the process. Sound familiar?
- You do not know if your lot even qualifies for an ADU, and every website tells you something different.
- You want to convert your garage but have no idea what the city requires structurally or where to start.
- A draftsman or online plan service got you halfway, and now the application is stuck in plan check corrections nobody is answering.
- Contractors are happy to quote the construction, but nobody wants to own the drawings and the permit paperwork.
- You have heard about setbacks, height limits and parking rules and cannot tell which ones apply to your property.
- Your garage was partially converted years ago without permits, and you are worried that blocks you from doing it right now.

ADU Plans & Permits costs in Mar Vista
What ADU plans and permits cost depends heavily on the project. A garage conversion using the existing structure is a very different scope than a new two-story detached ADU on a sloped lot. That is why you will not find standard prices here: they would be wrong for your situation more often than right.
- New construction or a conversion of existing space, such as a garage
- The size of the unit and the complexity of the design
- One story or two, and whether the ADU sits above or attached to another structure
- How much structural engineering the project needs, including the condition of an existing garage
- Whether your lot is in a hillside area or another zone that requires extra reports or clearances
- Soils or geology reports, when the location of the lot requires them
- A custom design versus a pre-approved plan from the LA ADU Standard Plan Program
- The scope of the Title 24 energy report and whether solar requirements apply
