Fast, Reliable General Contractor Across Highland
Most homeowners in Highland who call us are planning something big on a piece of property that comes with real constraints: county permits, fire-code triggers, septic setbacks, or a sloped lot that drains toward the foundation. That’s exactly the work our team handles every week. We’re a General Contractor with deep experience across the 92346 zip code, from the flats along Baseline to the foothill parcels where Chapter 7A changes the entire scope. If you’re planning an addition, ADU, or full remodel in Highland, call (833) 382-8544 and we’ll walk the property before we quote anything.
Why Gold Star Contractors Is Highland’s Preferred General Contractor Company
Highland is not Redlands. The permitting path, the fire-code requirements, and the way water moves across a sloped acreage lot are different here, and a contractor who treats Highland like any inland valley city will miss something expensive. We don’t. Noel Carranza built Gold Star Contractors around a simple discipline: scope the site before we price the job. That means walking the lot, checking the existing roof and vents, confirming whether the parcel is in the county’s jurisdiction or the city’s, and flagging Chapter 7A triggers before they become change orders.
We’ve done exactly this on a detached ADU off Baseline where an older wood-shake roof on the main house got flagged during permit review. The inspector required a Chapter 7A upgrade on the existing structure before the ADU could proceed. We had scoped that possibility and priced it into the quote, so the client didn’t eat a surprise. That’s what local expertise means in Highland: knowing what the inspector will flag before the inspector sees it. Call (833) 382-8544 and we’ll bring that same discipline to your project.

General Contractor Services in Highland
General Contractor Services in Highland cover the full build cycle: additions, detached ADUs, garage conversions, kitchen and bath remodels, and exterior systems like roofing, siding, and hardscaping. The work we do here leans heavily toward acreage properties, where a new structure means more than framing and drywall. It means grading, drainage, septic and well coordination, material staging, and often a longer schedule due to weather and access. A home addition in Highland typically runs $45,000 – $130,000 depending on square footage, foundation conditions, and whether Chapter 7A upgrades get triggered on the existing structure. An ADU runs $90,000 – $220,000 when you account for utilities, fire-resistant assembly requirements, and site work. A garage conversion falls in the $30,000 – $80,000 range.
Detached ADUs and Outbuildings
A detached ADU on a Highland acreage lot forces decisions most city lots never face. Where do the septic lines go? Is the well far enough from the leach field? Will the fire marshal require defensible space and ignition-resistant materials on the new structure? We handle all of it under one contract. We also coordinate prefab and panelized options through manufacturers like Abodu and Plant Prefab, which shortens construction time on properties where long material hauls and limited staging space are a problem.

Additions That Trigger Fire-Code Upgrades
This is the one that catches people. Add square footage to a home in Highland’s high-fire-severity zone and the entire structure, not just the new part, may need to meet Chapter 7A: ignition-resistant roofing, ember-resistant vents, and non-combustible siding at the eaves. A simple room addition can turn into a partial re-skin of the existing house. We price that reality upfront, not halfway through framing.

Construction Company in Highland
Construction Company work in Highland is different from tract-home remodeling. Many of the parcels we build on are unincorporated county land, which means county building and safety, county fire, and county environmental health all have a say. The permit path is longer, the inspections are stricter, and the consequences of a missed setback are real. We manage that process from the first site visit through final inspection. A new paver driveway on one of these properties runs $7,000 – $18,000. A concrete driveway runs $4,500 – $12,000. Roof replacement runs $8,000 – $20,000, and if the roof is wood shake, the replacement has to meet Chapter 7A assembly standards, which pushes the material conversation toward Class A rated options from manufacturers like GAF and CertainTeed.
Grading, Drainage, and Site Prep
Every sloped lot in Highland eventually tells you where the water wants to go. We handled a property off Baseline where a dirt driveway sloped toward the house and winter rains had already started undermining the foundation edge. Before we quoted the ADU, we scoped a swale, a retaining edge, and a compacted gravel turn-around wide enough for concrete trucks. That site work added about twelve percent to the total, but it protected the new structure and the old one. If your lot drains toward the house, that’s the first thing we look at.
Long Hauls and Equipment Access
Some Highland properties sit a quarter mile off the paved road. Concrete trucks, boom lifts, and material deliveries have to be coordinated around access width, overhead lines, and weather. We plan that before we quote. The price of a job on a difficult-access lot reflects the extra staging, the smaller equipment choices, and sometimes a pumper truck for concrete. We don’t hide that cost in a change order later.
Trusted Brands We Service in Highland
We specify brands that hold up to Highland’s dry heat, Santa Ana winds, and wildfire exposure. For exterior doors we work with Therma-Tru, for vinyl fencing systems with Master Halco and Barrette, and for windows we’ve installed ViewLux units on several Highland remodels. Because we stock common components and hardware locally for our Highland jobs, we avoid the week-long parts run that stalls a project. When a material matters to fire code or to longevity in this climate, we’d rather specify a brand we’ve already installed and stood behind on other Highland properties.

AfterCommon General Contractor Problems We See in Highland Homes
- Wood-shake roofs that fail Chapter 7A review. We see this constantly on older foothill homes. The homeowner budgets for an addition and discovers the inspector won’t sign off until the entire roof assembly gets upgraded to a Class A ignition-resistant system.
- County permitting mix-ups on unincorporated parcels. A property with a Highland mailing address is not automatically under city jurisdiction. Assuming city rules apply leads to filed plans getting rejected and weeks of delay.
- Grading and drainage failures on sloped lots. Without proper site assessment, winter rains erode slopes and direct water at foundations. We’ve repaired enough of these to always scope drainage first on any Highland acreage job.
- Septic and well setbacks that kill an ADU layout. County environmental health rules dictate where a leach field can sit relative to a well and a new structure. If you design the ADU before checking those setbacks, you may be redesigning it twice.

FAQs About General Contractor in Highland
If your parcel sits in unincorporated Highland, yes, county building and safety and county environmental health both review the ADU plans, including septic and well setbacks. If you’re within city limits, the city handles it. We check jurisdiction before we quote, and we pull all the permits either way. That eliminates the most common delay we see on Highland ADU projects. Call (833) 382-8544 and we’ll confirm your parcel’s status for free.
Chapter 7A requires ignition-resistant roofing, ember-resistant vents, and non-combustible siding on new construction and additions in Highland’s high-fire-severity zone, and it can extend to the existing structure if you’re adding square footage. We scope the required upgrades during the estimate, not after the inspector flags them. Call (833) 382-8544 if you’re planning an addition and want to know whether Chapter 7A applies to your home.
Expect us to walk the lot and map where water flows before we quote. On most Highland sloped parcels, you’ll need a swale, a compacted edge, or a retaining element to keep runoff away from the foundation, and that work typically adds several thousand dollars to the project. We price it in writing up front. Call (833) 382-8544 to schedule a free site assessment.
Yes. We stage materials at the nearest accessible point, coordinate concrete trucks and lifts around your access width, and price any pumper or smaller-equipment requirements into the quote before work starts. We don’t hit you with an access surprise mid-project. Call (833) 382-8544 and we’ll walk your driveway with you.
We pull every permit, schedule every inspection, and stay on site for each one. For county parcels, that means managing building and safety, fire, and environmental health reviews. For city parcels, it means the city’s plan check and inspection process. The permit path in Highland is stricter than nearby cities, and we plan the schedule around it from day one. Call (833) 382-8544 to get your project scoped and permitted correctly.
