Highland Park holds the city's largest HPOZ, Highland Park-Garvanza, and a dense Craftsman inventory to match. SurveyLA states that Highland Park's built environment reflects its early-20th-century development, with a large number of intact single-family and multifamily residences, primarily in the Craftsman style with a few Victorian examples, and that Craftsman architecture from the 1900s and 1910s is the predominant style in the HPOZ. Queen Anne, Shingle, Mission Revival and Tudor Revival also appear in the HPOZ. That is a preservation scope, not a cosmetic one.

Popular services in Highland Park: Kitchen Remodeling, Bathroom Remodeling, Whole Home Renovation, ADU Construction, Garage Conversion. 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 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. Craftsman kitchens here keep built-ins and porches in the design.
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. Baths in 1900s and 1910s houses are rebuilt around drains 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. Whole-home work resequences systems with restoration, not after it.
View details ↗04An 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. Flat-lot ADUs are decided by zoning and preservation-plan limits, per parcel.
View details ↗05A 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 on flat lots are the companion ADU path.
View details ↗Renovations in Highland Park run on this neighborhood's constraints: its housing, its lots and its parcel rules. These are the three most common project types here.
Largest means more parcels, more contributors and more commercial buildings under one preservation plan, so review timelines and scope questions are larger here than in a small HPOZ.
Contributor versus non-contributor status for the parcel is confirmed first, because it changes what the plan reviews for that house.
Call us →Craftsman restoration in Highland Park keeps arroyo stone, built-ins and porches while modernising kitchens, baths and systems behind them.
Systems work on 1900s to 1910s houses is sequenced with restoration, not after it: wiring, plumbing and foundation work that damages restored fabric is work done twice.
Call us →Commercial buildings inside the HPOZ face preservation review as well as house stock, a rare mixed-use preservation case that changes storefront and facade scopes.
A commercial-corridor scope therefore checks HPOZ status for the building before design, alongside ordinary commercial and LADBS requirements.

Call (424) 337-6597 →October 2026 market guides, not a quote from Radiant Renovations Co. 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 and a primary bath at $35,000-$85,000, a detached ADU at $180,000-$450,000 or more, and a ground-floor room addition at $250-$650 per square foot. 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. HPOZ restoration scopes make kitchen, bath, whole-home and ADU guide bands the relevant starting points here, with preservation-plan limits shaping all of them. 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 Highland Park-Garvanza 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.
Its size and its commercial coverage: it is described as the city's largest HPOZ, and its preservation plan covers commercial buildings on Figueroa and York as well as houses. That means corridor scopes need the same boundary check as house scopes.
