Fast, Reliable General Contractor Across Lake Forest
Finding a General Contractor who understands Lake Forest means knowing the difference between a city permit and an HOA architectural sign-off. Most work here needs both, and most contractors only track one. Nelson Ibarra and the team at Alder Contractors have built whole-home remodels, room additions, and exterior replacements across the 92630 zip code for years, and we sequence that dual approval from day one so your project doesn’t stall at a monthly committee meeting. Call us at (833) 467-7020 to talk through your scope before you pull anything.
Why Alder Contractors Is Lake Forest’s Preferred General Contractor Company
Lake Forest homeowners tell us the same thing on every walkthrough: they want one contractor who can handle the kitchen, the roof, the windows, and the backyard patio without juggling four different crews. That’s the Alder model. From the roofline to the backyard, we run every trade under a single contract, which matters when your HOA wants one point of contact for the architectural committee. We’ve worked in communities along Trabuco Road and off Lake Forest Drive, so we know which associations want shingle samples at submittal and which ones care more about fence height than fascia color — experience that shapes our Lake Forest CWS service.
We also show up with specifics. Alder has access to more than 50 established material brands including GAF and CertainTeed roofing, KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, Kohler and Toto fixtures, and James Hardie siding. That means the allowance in your written scope references a real product line, not a vague builder-grade placeholder. Nelson Ibarra reviews every submittal before it goes to the city or the HOA, because he’s the one who answers when the committee has questions.
Styles & brands we work with







Hire a General Contractor in Lake Forest
Hire a General Contractor in Lake Forest when your remodel touches more than one trade, and you’d rather not spend your weekends coordinating plumbers, electricians, and cabinet installers who never seem to be in the same room. A mid-range kitchen remodel in Lake Forest typically runs $14,000 – $45,000 depending on cabinet grade, countertop material, and how much of the original 1970s plumbing and wiring you want to keep. A bathroom remodel falls between $9,000 – $28,000. The point of hiring is the coordination, which is also the part homeowners underestimate most.
Our General Contractor in Lake Forest work starts with a written scope of work, not a handshake. We list what gets demolished, what gets replaced, what brand goes where, and what the allowance covers. If your HOA needs a submittal packet, we prepare it before demolition starts so the architectural committee reviews while we pull the city permit. That overlap saves weeks on exterior projects.
Kitchen and Bath Scope
Lake Forest tract homes from the 1960s and 1970s were built with original stucco-and-wood-frame construction, which means original window openings, original copper-era wiring, and original subfloors that have been under vinyl for five decades. A kitchen remodel here often starts with opening a wall and finding a subfloor that swelled under the original vinyl, so we sister the joists, re-run the rough-in, and set the cabinets on a level surface before any finish work begins. You can keep the original footprint and still get KraftMaid cabinets with a Cambria quartz island top.
Exterior and Structural Scope
Roof replacement in Lake Forest runs $8,000 – $20,000, and window replacement runs $4,500 – $15,000, but the real cost driver is sequencing. Santa Ana wind season hits the foothills near Whiting Ranch and Serrano Creek hard, so fire-hardening upgrades like Class A roofing, ember-resistant vents, and fire-rated siding are common requests. We coordinate those with your HOA’s architectural committee, because a shingle profile rejected after tear-off is an expensive fix.
General Contractor Services in Lake Forest
General Contractor Services in Lake Forest cover the work a homeowner can’t coordinate alone: full interior remodels, exterior replacement, room additions, ADU construction, and hardscaping that extends beyond the walls of the house. A room addition in Lake Forest costs $45,000 – $130,000, and an ADU runs $90,000 – $220,000, but both require the same thing: a written scope, a city permit, and HOA architectural approval running in parallel. We handle all three.
If you’re adding square footage, we also check your builder warranty language before we touch a wall. Touching the wrong structural wall can void remaining coverage on a home that’s still under warranty, even if the city permit is clean. That’s a Lake Forest-specific problem we see regularly.
Whole-Home and Addition Scope
Whole-home remodels in Lake Forest often start with the kitchen and both baths, then extend to windows, doors, and the roof as the owner realizes the original 1970s systems are all reaching end of life at the same time. A full exterior replacement with James Hardie siding, PGT windows, and a GAF roof can be sequenced in phases, but we find that bundling the trades under one contract saves money and keeps the HOA committee happy because they review everything once instead of three times.

ADU and Garage Conversion Scope
Garage conversions in Lake Forest run $30,000 – $80,000 and are popular in single-story tracts where the lot has room but the house doesn’t. ADU construction runs $90,000 – $220,000 and often goes in the backyard behind an existing two-car garage. Alder has direct experience with prefab ADU partners like Abodu and Dvele, which gives Lake Forest homeowners a path to added living space or rental income without sourcing a separate specialist.

AfterCommon General Contractor Problems We See in Lake Forest Homes
- Skipping HOA architectural review because it’s ‘just a re-roof.’ The community then rejects the shingle profile after tear-off, and the owner is out the tear-off cost plus the re-do. We submit the shingle sample, the profile, and the color to the committee before anything comes off the roof.
- Pulling a city permit without checking builder warranty language. Touching a structural wall on a newer Lake Forest home can void the remaining coverage on that wall, even if the city approved the drawing. We read the warranty before we write the scope.
- Quoting builder-grade replacement finishes with vague allowances. The owner signs, the change orders start, and the final bill is $15,000 over the bid. Our written scopes reference specific product lines, not ‘contractor’s choice’ allowances.
- Replacing windows and doors without sequencing for Santa Ana winds. Lake Forest foothill edges near Whiting Ranch catch strong gusts. We order and install windows and doors in the right sequence so the envelope is sealed before the wind season, not after.

FAQs About General Contractor in Lake Forest
Yes, both approvals run in parallel, but the HOA architectural committee often meets monthly, which means you want the submittal packet ready before you pull the city permit. We prepare both documents at the same time so neither one waits on the other. Call (833) 467-7020 and we’ll walk you through the exact sequence for your community.
It depends on what you touch. Structural walls, electrical panels, and plumbing rough-ins can void coverage on those systems if modified improperly, even with a city permit. We read your builder warranty before we write the scope, and we avoid touching systems that would trigger a void unless you specifically ask us to. Call (833) 467-7020 for a free scope review.
Start with the kitchen and primary bath, because those are the rooms where builder-grade cabinets, countertops, and fixtures show age first. A kitchen remodel in Lake Forest runs $14,000 – $45,000 and a bathroom remodel runs $9,000 – $28,000. We name the brands in the scope so you know what you’re getting before we order anything.
Plan for the HOA architectural committee’s monthly meeting to add two to four weeks on top of the city permit review, plus construction time. A room addition in Lake Forest typically runs four to seven months from signed scope to final inspection, depending on the community’s committee schedule. We sequence the submittal so the clock starts early. Call (833) 467-7020 for a project-specific timeline.
A permit means the city inspected the work and the work passed. In Lake Forest, where nearly every home sits inside an HOA, a permit also protects you when you sell, because unpermitted work shows up in escrow and kills deals. We pull permits on every project where they’re required, and we pass inspections before we call the job done.
