ADU Company in Highland - Design, Permits and Build Under One Contract

ADU Company in Highland, CA

Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions across Highland, CA. Most of the homes we work on here are 1960s to 1980s ranch builds on lots between 6,000 and 10,000 square feet, which means there’s usually room for a detached ADU. What changes the job in Highland is fire zone mapping. A meaningful share of the neighborhoods north of Base Line sit in Very High Fire Hazard Severity Zones, and that designation reshapes the budget before we ever submit plans.

Why Highland Homes Are Different

Highland’s housing stock skews older, and the electrical systems show it. A large share of the homes we assess still run 100-amp panels, with galvanized plumbing that predates modern PEX and copper standards. Adding an ADU with its own kitchen, laundry, and mini-split HVAC means upgrading that panel and often re-piping portions of the main house. We plan for that from the first site walk, so the written price we give you already includes the panel upgrade and re-pipe scope, not a surprise change order later.

The foothill factor is the bigger variable. On streets climbing toward Panorama and the upper tract developments, parcels frequently fall inside CAL FIRE’s Very High Fire Hazard Severity Zone map. That triggers California Building Code Chapter 7A requirements: ember-resistant vents, fire-rated siding, and Class A roofing. A zone designation most homeowners only discover at permit intake can add $15,000 to $25,000 to a detached unit. We pull the FHSZ map lookup before drawing the first plan, because finding out after intake means a redesign, a delay, and a number that no longer matches what we quoted. Highland’s elevation also brings wider temperature swings and harder freezes than the valley floor, so we spec exposed utility connections and rooftop equipment accordingly.

Our Main Highland Services

Highland homeowners typically come to us for one of three things: adding square footage to the existing house, converting an attached or detached garage into living space, or building a standalone ADU in the backyard. Each has its own permitting path and its own fire-zone considerations in Highland.

Home Addition Contractor in Highland

Home additions in Highland usually mean expanding a ranch home outward or upward, and the older construction underneath matters as much as the new framing. A 1960s home with a 100-amp panel and galvanized supply lines will need electrical and plumbing work before the addition ties in. In foothill-adjacent tracts, the addition also has to meet the same Chapter 7A ignition-resistant standards as new construction if the parcel is mapped VHFHSZ. We scope all of that up front so the price we write is the price you pay. Home Addition Contractor in Highland

Garage Conversion Contractor in Highland

Garage conversions are often the fastest path to a rentable unit or a private suite for family, and Highland’s larger lots frequently have attached two-car garages that convert cleanly. The catch is that a garage built in the 1970s or 1980s rarely has the slab insulation, electrical capacity, or ceiling height current code requires for living space. If the parcel is in a fire hazard zone, the garage’s existing roof and wall assemblies may need upgraded cladding before the conversion passes inspection. We walk the space, check the zone map, and give you a written price that reflects what the permit office will actually require. Garage Conversion Contractor in Highland

ADU Builders in Highland

Detached ADUs make the most sense on Highland lots, and the generous 6,000 to 10,000 square foot parcels give us real flexibility on placement. The first question we answer is always the fire zone: north of Base Line, many parcels are VHFHSZ, and that one designation changes siding, venting, and roofing specs across the whole structure. For flatland parcels south of Base Line, a standard detached ADU permits without those Chapter 7A add-ons. Either way, our ADU Builders in Highland page covers the full build process from site assessment through final inspection, with real price ranges and timelines. ADU Builders in Highland

Brands We Service in Highland

We work hands-on with established prefab and panelized ADU systems including Abodu, Cover, and Dvele, and we match the manufacturer to the lot, the budget, and the fire-zone requirements. The right prefab path can compress a Highland ADU timeline by weeks, but only if the model’s cladding and venting already meet Chapter 7A where the parcel requires it. See our brands for the full breakdown.
