Mar Vista's defining story is small: the Gregory Ain Mar Vista Tract, 52 modest homes of about 1,100 square feet designed by Gregory Ain with landscape designer Garrett Eckbo in 1948, became an HPOZ in 2003 and is described as the city's postwar-architecture HPOZ example. Expanding a 1,100-square-foot modernist home without breaking its logic is the central Mar Vista design problem, and it is a different problem from standard postwar remodeling outside the tract.

Kitchen work starts with layout, storage and the condition of the walls behind the cabinets. We rebuild with new cabinets, countertops and backsplash, and we deal with whatever the existing plumbing and wiring require once walls are open. Ain tract kitchens here are preservation-sensitive and small-footprint.
View details ↗02Bathroom work is mostly what you cannot see: drains, venting, waterproofing and subfloor. We rebuild showers and baths with proper membranes and tile, and we fix the substrate problems that make new tile crack. Small modernist baths gain function without breaking the house logic.
View details ↗03A whole-home project resequences systems before finishes: envelope, wiring, plumbing and structure first, then rooms. That order matters most in older houses, where one opened wall can change the scope of the next room. Whole-home work in small modernist houses resequences systems first.
View details ↗04An addition is decided by setbacks, floor-area limits and how the new roof and foundation tie into the old house. We frame, sheath and finish additions to read as part of the original house, not as a box stuck on the back. Additions on small lots are kept subordinate to the original house.
View details ↗05An accessory dwelling unit is a small house with its own kitchen, bath and utilities, and its feasibility is a zoning question first. We check setbacks, floor area, parking and utility capacity for the parcel before designing the unit. ADUs on small flat lots are decided by setbacks and parking.
View details ↗06A garage conversion reuses an existing foundation and walls, which is why it often costs less than a detached unit. It still needs proper ceiling height, egress, insulation, electrical and plumbing to be a legal living space. Garage conversions are the small-lot path to a second unit.
View details ↗Renovations in Mar Vista run on this neighborhood's constraints: its housing, its lots and its parcel rules. These are the three most common project types here.
Expanding a 1,100-square-foot Ain home means adding a room, a bath or a garage ADU while keeping the modernist logic: low horizontal lines, indoor-outdoor flow and a legible site plan.
Additions are kept subordinate to the original house in massing and materials, and HPOZ review is sought for the specific parcel and scope, not assumed from the tract name alone.
Call us →Inside the tract, HPOZ review governs exterior and character-defining changes under the preservation plan. Interior kitchen and bath work is planned with that boundary in mind.
What needs approval and what does not is confirmed for the parcel before design, so a kitchen refresh does not stall on an exterior detail that was never in the scope.
Call us →On a small Mar Vista lot, the garage ADU and the rear addition compete for the same scarce space. The decision follows setbacks, parking, floor area and how the household uses the yard.
A garage ADU creates a second unit with its own kitchen and bath; a rear addition keeps one home larger. The lot pattern and the tract rules, where they apply, decide between them.

Guides conflict (for example, Angi's smaller-scope bathroom average sits well below contractor-guide primary-bath ranges), so we do not collapse them into a single average. Small-home scopes make kitchen, bath, addition and ADU guide bands the relevant starting points here. Your price depends on scope, layout changes, structure, permits and finishes, and it is set only after an inspection.
Most remodeling in the City of Los Angeles needs a permit from LADBS when it moves plumbing or electrical, changes structure, or adds floor area; ADUs, room additions and deck work generally require permits. HPOZ review inside the Ain tract can sit in front of an LADBS permit; outside the tract, ordinary zoning governs. Permits, plan check and inspections are sequenced before finishes, and clearances can sit in front of a permit, for example historic review where it applies to a parcel.
Several rules are decided per address, not per neighborhood: whether a parcel is an HPOZ contributor, in a Very High Fire Hazard Severity Zone, in a Hillside Area, subject to the Rent Stabilization Ordinance or a soft-story order, or in a flood or coastal zone. Check the address in ZIMAS, LADBS and LAFD maps before assuming any of those rules apply, or do not apply, to your home.
No. HPOZ review applies inside the Gregory Ain Mar Vista Tract, not to Mar Vista as a whole. Outside the tract, ordinary City of Los Angeles zoning and LADBS permits govern, and this page does not apply tract rules beyond its boundary.
