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. Mid-century hillside kitchens here keep glass and slope logic.
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. Hillside baths are rebuilt around drains, venting and waterproofing.
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. Hillside whole-home work starts with foundations and drainage.
View details ↗04Decks stand or fall on foundations and ledger connections. Posts are set on proper footings, framing follows slope and soil, and rot and failed ledgers are repaired before new boards and railings. Hillside decks are structure-and-drainage projects first.
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. Steep-lot ADUs begin with the two-map test for the parcel.
View details ↗Renovations in Mount Washington run on this neighborhood's constraints: its housing, its lots and its parcel rules. These are the three most common project types here.
Restoring a mid-century hillside home keeps its organic hillside logic: stepped levels, glass, natural materials and a structure that follows the slope, rather than a generic modernisation that flattens it.
Glass, decks and structure are upgraded together, so the house keeps its character while gaining performance and safety.
Call us →A house reached by a long stair run needs access designed in: staging and delivery routes, storage at street level where possible, and interior layouts that reduce daily stair dependence.
Ageing-in-place design on a hilltop lot is therefore a ground-floor and access question first, and a finishes question second.
Call us →On a Mount Washington slope, caissons, retaining walls and drainage are the first scope, not an add-on. A kitchen, deck or ADU built over unresolved slope water or foundation movement will not last.
That below-grade scope is priced and sequenced before visible work, so the finished rooms rest on stable ground.

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. Hillside scopes make whole-home, deck and ADU guide bands relevant alongside kitchen and bath bands 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. Hillside, VHFHSZ and Baseline Hillside clearances can sit in front of an LADBS permit for hillside parcels. 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.
Access and slope: single-lane streets, stair runs, no street parking on some stretches, and foundations, retaining walls and drainage that must be resolved before visible work. Those constraints are planned first, not discovered during construction.
