California's ADU laws have made backyard units one of the highest-leverage property improvements an LA homeowner can make. We design and build all three types — detached new builds, attached additions, and JADUs (Junior ADUs converted from existing space). End to end. Permits, plans, foundations, framing, finishes, and final inspections, all under one roof. You work directly with Onn from feasibility study through certificate of occupancy.
Every neighborhood has its own architectural character, permit jurisdiction, and finish-level expectations. Here's how we approach adu construction in Mar Vista specifically.
Mar Vista homes are predominantly 1945–1965 builds. Original electrical service is often 100-amp and needs upgrade. Galvanized supply pipes are common. Single-pane windows, knob-and-tube wiring sometimes lurking. We plan for these during any kitchen or bath remodel.
Many Mar Vista lots are 50'×140' or larger — good fits for detached ADUs of 800–1,200 sq ft. Conversion of 1-car garages to JADUs is also common. State ADU laws strongly support these projects in Mar Vista.
Mar Vista has an active community council and many homeowners value preserving mid-century character. We design remodels that respect this — modern function, period-appropriate aesthetic.
Mar Vista has been a consistently active LA neighborhood for ADU permits in recent years. The active market reflects the lot economics — typical Mar Vista R-1 parcels support a detached ADU at or near state-law maximum with adequate setbacks. We design the ADU placement against the parcel's real survey so the design fits the actual lot rather than the idealized assessor sketch.
The Mar Vista ADU client mix includes a significant rental-income subset alongside the guest-suite and family-housing motivations seen in other neighborhoods. Program reflects that: studio or 1-bed configuration, separate entrance with mailbox, in-unit laundry, full kitchen with simpler appliance package. We scope the rental-oriented ADU for durability and turnover rather than for owner-occupied finish quality.
Mar Vista garage-conversion to ADU is generally cheaper and faster than detached new-build for clients prioritizing speed-to-rental or lower up-front investment. Existing detached garages at the rear of the lot typically convert well to a studio ADU with shared driveway access. We evaluate the existing garage's slab, framing, and roof condition before recommending conversion versus new-build, because conversion economics depend heavily on what's already there.
Lot review, setbacks, height limits, utility access, soil assessment. We tell you up front whether your project pencils — square footage, code constraints, expected timeline.
Floor plans, elevations, 3D renderings. We design to maximize functional space within California's ADU size limits (up to 1,200 sq ft detached, 850 sq ft for studios/1-bedroom).
Plan check submission, energy compliance (Title 24), structural engineering, separate or shared utility service. We deal with LADBS or your municipal building department.
New foundations or attached construction, framing, mechanical/electrical/plumbing (MEP) rough-in, exterior, and full interior finishes — kitchen, bath, flooring, HVAC, electrical.
Final inspections, Certificate of Occupancy, and walkthrough. We hand you a unit you can live in, rent, or use as a guest house.
Typical detached ADU build cost in Los Angeles, all-in (design, permits, construction, finishes, utility hookups). Attached ADUs typically run lower; JADUs converting existing space lower still.
LADBS handles Mar Vista permits. Standard plan check timelines (4–10 weeks) for kitchens. ADU projects benefit from state-level ministerial approval where applicable.

California state law allows detached ADUs up to 1,200 sq ft (or larger if your local jurisdiction permits). Attached ADUs are limited to 50% of the primary home's square footage or 1,200 sq ft, whichever is less. Junior ADUs (JADUs) are capped at 500 sq ft and must be inside the existing primary structure.
Plan to design and build a detached ADU in 9–14 months total: 2–3 months for design and permits, 6–10 months for construction. Attached ADUs and JADU conversions can run shorter.
In Mar Vista, frequently. Most pre-1970s homes here have at least one of: knob-and-tube wiring, galvanized pipes, or asbestos floor tile under the linoleum. We test for hazardous materials before demo and budget contingency.
In most cases, yes. We do a feasibility check up front — setbacks, height limits, utility access, soil. We tell you whether a detached ADU pencils or whether a JADU conversion makes more sense.
Side-by-side comparison of detached ADUs and garage conversions for LA homeowners — costs, timelines, ROI, rental income, and which one adds more value on resale.
