Sun Valley mixes northeast Valley postwar tract stock and industrial-adjacent stock, with one named exception inside it: the Stonehurst HPOZ, a historic stone-house tract in the Sun Valley area, listed on the city HPOZ list. That split is the page: ordinary tract and ADU scopes across Sun Valley, and HPOZ-sensitive stone-house work inside Stonehurst only.

Popular services in Sun Valley: Kitchen Remodeling, Bathroom Remodeling, Room Additions, ADU Construction, Whole Home Renovation. Each scope is planned for this neighborhood's housing, lots and parcel rules, not copied from a neighbouring page.
Kitchen work starts with layout, storage and the walls behind the cabinets. We rebuild with new cabinets, countertops and backsplash, dealing with whatever existing plumbing and wiring require once walls are open. Tract kitchens here are planned around layout and structure.
View details ↗02Bathroom work is mostly hidden: drains, venting, waterproofing and subfloor. Showers and baths are rebuilt with proper membranes and tile, and substrate faults that crack new tile are fixed. Tract baths are planned around drains, venting and waterproofing.
View details ↗03An 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 flat streets favour primary suites and family rooms.
View details ↗04An ADU is a small house with its own kitchen, bath and utilities, and zoning feasibility is the first question. Setbacks, floor area, parking and utility capacity are checked for the parcel before design. Flat-lot ADUs are decided by setbacks and parking, per parcel.
View details ↗05A 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 tract houses resequences systems first.
View details ↗Renovations in Sun Valley run on this neighborhood's constraints: its housing, its lots and its parcel rules. These are the three most common project types here.
Stonehurst's stone houses need stone and mortar craft: repointing, matching stone, repairing rather than replacing period fabric, and keeping the tract's character legible.
HPOZ review inside Stonehurst governs exterior and character-defining changes under the preservation plan, confirmed for the parcel before design.
Call us →Outside Stonehurst, Sun Valley tract work is ordinary northeast Valley scope: kitchen and bath renewal, rear additions and ADU feasibility on flat streets.
Additions are decided by setbacks and floor area, and ADUs by zoning, parking and utility capacity, per parcel.
Call us →Where Sun Valley homes sit near industrial corridors, sound, screening and yard design become part of a remodel scope.
Those retrofits are specified per parcel: window and door sealing, fencing and planting that screen without creating drainage or access problems.

Call (424) 337-6597 →October 2026 market guides, not a Radiant Renovations Co. quote and not a price for this neighborhood, put a mid-range Los Angeles kitchen at roughly $45,000-$100,000, a hall or guest bath at $15,000-$40,000, a primary bath at $35,000-$85,000, a detached ADU at $180,000-$450,000 or more, and a ground-floor addition at $250-$650 per square foot. Because guides conflict — Angi's smaller-scope bathroom average, for example, sits well below contractor-guide primary-bath ranges — they are not collapsed into a single average. Tract scopes make kitchen, bath, addition and ADU guide bands the relevant starting points here. Any project's price depends on scope, layout changes, structure, permits and finishes, and 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 Stonehurst can sit in front of an LADBS permit; outside it, 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. Stonehurst is a tract inside the Sun Valley area, and HPOZ review applies inside its boundaries, which are flagged for verification. Most Sun Valley tract stock is not in Stonehurst, and this page does not apply its rules beyond its boundary.
