Get your free estimateFast, Reliable Home Addition Contractor Across Mar Vista
Adding a bedroom, bathroom, or second story to a Mar Vista home takes a contractor who knows how flat R1 lots on the east side differ from hillside parcels up on Mar Vista Hill. We’ve been building additions across Mar Vista since 2010, and we understand what works on a 5,000 sq ft flat lot versus a sloped street off Grand View Boulevard. Most importantly, we put every price in writing before work begins, so you never get a door-knock surprise after demolition starts.

Why Lodgewick ADU Los Angeles Is Mar Vista’s Preferred Home Addition Contractor Company
Homeowners in Mar Vista call us back because we show up when we say we will, leave the job site clean, and stand behind the work with a written guarantee. Russ Delmar leads our team, and he’s been building on Mar Vista’s housing stock – mostly 1940s and 1950s ranch homes on rectangular lots – for over a decade. We’ve worked on post-and-beam framing under low-pitch roofs all over the neighborhood, from Marina del Rey adjacent streets to the hillside pockets near Beethoven Street.
Every Lodgewick addition operates under The Kingswell Guarantee. That means a written price before work starts, a defined arrival window for our crew, a clean job site at the end of each day, and a written guarantee that covers the work for 365 days. If anything isn’t done right, we come back. That’s a free return visit, not a re-quote.
We also answer the phone. A live person picks up 24/7, so when a Mar Vista homeowner has a question mid-build, someone answers who can actually help. No voicemail loops, no gatekeeping.
Bathroom Addition Contractor in Mar Vista
A bathroom addition in Mar Vista usually means converting underused square footage into a full or three-quarter bath, often off a back hallway or as part of a primary suite expansion. On most Mar Vista ranch homes, the existing footprint has room to push out 6 to 8 feet without triggering deeper foundation work, especially on flat lots south of Venice Boulevard.
What a Mar Vista Bathroom Addition Involves
We run new supply and drain lines, add exhaust ventilation sized for a coastal climate, and handle waterproofing around tub or shower surrounds. Given marine layer moisture in Mar Vista, we spec continuous bathroom venting that actually moves humid air out, not just a recirculating fan that moves it around. A typical bathroom addition here runs $38,000 to $72,000 depending on fixture level and whether it’s a wet-room layout or standard tub-and-shower combination.
When It Makes Sense to Add Rather Than Remodel
If your Mar Vista home is a two-bedroom, one-bath ranch, adding a second bath changes how the house functions daily. It removes the morning bottleneck and adds meaningful resale value on the Westside. We walk the lot with you before quoting to check sewer lateral locations and whether the slab is post-tensioned or conventional – both affect the plumbing scope and the written price we give.
Bedroom Addition Contractor in Mar Vista
A bedroom addition in Mar Vista often takes two forms: a bump-out on the first floor that adds 150 to 250 sq ft, or a second-story addition for a primary suite with a view. Both are common on Mar Vista’s 5,000 to 7,500 sq ft lots, but the second-story version on Mar Vista Hill works differently with the R1 Variation Zone.
Bump-Out Bedroom Additions on Flat Lots
On flat lots south of Palms Boulevard, we frequently add a single bedroom by extending the back wall. These additions typically require a simple foundation extension, fresh roof tie-in, and a rework of the exterior siding. A flat-lot bedroom bump-out in Mar Vista runs roughly $60,000 to $115,000 depending on closet build-out, window package, and whether we’re adding an en-suite bath.
Second-Story Bedroom Additions on Mar Vista Hill
Up on Mar Vista Hill, a second-story bedroom addition with a view deck is one of the highest-value projects a homeowner can take on. The R1 Variation Zone allows two-story additions with rooftop decks that capture ocean breezes over the Westside – an opportunity that simply does not exist in flatland Venice or Palms. This is a significant structural scope: we engineer shear walls, tie the new framing into the existing post-and-beam structure, and coordinate hillside grading and drainage with the city’s review process. A second-story bedroom addition on Mar Vista Hill typically runs $180,000 to $340,000 depending on deck size, finish level, and hillside retaining work.
Trusted Brands We Service in Mar Vista
Our team works hands-on with leading ADU and addition systems, including Abodu, Cover, and James Hardie. On Mar Vista projects, we’re familiar with how Abodu’s factory-built modules handle the 1940s lot geometries common in this neighborhood, and how Cover’s panelized systems integrate with existing post-and-beam framing. For exterior finishes on marine-layer-exposed additions, we regularly spec James Hardie fiber cement siding – it holds up better than traditional stucco against the moisture Mar Vista’s morning fog brings. Because we build with these systems regularly, we can source materials faster and sidestep the parts delays that stall additions mid-project.
Common Home Addition Contractor Problems We See in Mar Vista Homes
- Treating Mar Vista Hill’s R1 Variation Zone like flatland R1. Homeowners on the hill leave significant square footage and a view deck on the table when a contractor doesn’t know the variation zone rules. We scope every hillside job specifically to the R1 Variation Zone before quoting.
- Underestimating marine layer moisture. Morning fog off the Pacific settles into Mar Vista consistently, and a poorly ventilated addition near the coast will show mold inside wall cavities within two years. We detail ventilation and exterior finishes for marine-layer exposure on every project.
- Not scoping long material hauls on narrow hillside streets. Some Mar Vista Hill streets off Grand View Boulevard are tight, with limited staging space. A contractor who doesn’t plan for equipment access and material staging hits you with change orders mid-project. We walk the site and factor hauling and staging into the written price up front.
- Foundation surprises on 1940s slab homes. Many Mar Vista ranch homes have non-standard slab depths or aging concrete that shows fine cracks. We inspect the foundation before quoting so the written price includes any needed reinforcement, not a costly add-on after we open the floor.

FAQs About Home Addition Contractor in Mar Vista
Usually yes. Many Mar Vista detached garages are unpermitted older structures with a simple perimeter foundation, not a reinforced slab. Converting one to living space means adding a proper foundation, upgrading the framing to meet current shear requirements, and running new electrical and plumbing. A garage conversion in Mar Vista typically runs $85,000 to $160,000 if the garage is structurally sound, more if we’re rebuilding the foundation. Call (213) 698-7116 and we’ll inspect the garage and give you a written price.
Yes, and that’s exactly what the R1 Variation Zone is for. In the Mar Vista Hill pocket, the variation zone allows two-story additions with rooftop decks specifically to capture ocean breezes and Westside views. We engineer the addition’s roofline to preserve your sightlines, and we coordinate grading and drainage with the city’s hillside review so the new structure doesn’t block your existing view. The short answer: a well-scoped Mar Vista Hill addition protects the view, not the other way around.
Morning fog off the Pacific brings consistent moisture that settles on exterior surfaces. For a Mar Vista addition, that means we spec materials and details that shed moisture: James Hardie fiber cement siding instead of stucco, continuous soffit ventilation to dry wall and roof cavities, and exterior caulks and flashings that hold up to damp, salty air. We don’t treat Mar Vista like inland LA. Siding that works in Culver City performs differently two miles east of the Pacific.
Yes. On Mar Vista’s flat, rectangular R1 lots, an ADU bathroom addition must meet setback requirements and sewer lateral capacity rules. Many 1940s ranch homes share a sewer lateral, which means adding a full bath with a tub can trigger a lateral upgrade depending on line condition and fixture count. We scope this before quoting so the written price includes any lateral work, not a surprise line item after excavation starts.
Beyond the framing and drywall, a bedroom addition on a 5,000 sq ft Mar Vista lot requires foundation planning, window and exterior finish work, electrical to code, and ventilation that handles coastal moisture. On most Mar Vista homes, the existing electrical panel is original 100-amp service, so we often include a panel upgrade or subpanel in the written price. We also check whether the lot has room to expand without triggering variance review – flat lots south of Venice Boulevard usually do, hillside lots east of Beethoven Street sometimes don’t. We handle all the scoping before we quote, so the price you see is the price you pay.
