Fast, Reliable General Contractor Across Garden Grove
Most Garden Grove homeowners don’t need a contractor who just swings hammers. They need someone who knows what’s behind these 1960s stucco walls before the first permit is pulled. That’s what Key Step Construction does differently. We’re a full-scope General Contractor team working from the roof to the foundation, and we know the tract homes across ZIPs 92840 through 92845 like the back of our hand. Call (855) 382-0824 and you’ll get Noel Garrity, the owner, on the line. Not a call center. Not a commissioned salesperson. Just a contractor who’s walked hundreds of Garden Grove floorplans and knows exactly what they’re hiding.
Your home was built for a different generation of living. Now it might hold three generations under one roof. That’s where we come in.
Why Key Step Construction Is Garden Grove’s Preferred General Contractor Company
We didn’t earn Garden Grove’s trust by marketing harder. We earned it by showing up with a plan. Most of our Garden Grove work comes from referrals in the Korean and Vietnamese communities around Garden Grove Boulevard and Bolsa Avenue, where word travels fast when a contractor actually communicates clearly through permitting and inspection.
A typical Garden Grove remodel for us starts with a walkthrough of the existing structure, not a glossy render. We check what’s permitted, what isn’t, and what the city will require once walls are open. That matters in this city more than almost anywhere in Orange County, because unpermitted garage conversions and second kitchens are everywhere. Our clients know they’re getting honest scope of work before we ever quote a dollar figure. And they know the first inspection won’t be a surprise.

Licensed General Contractor in Garden Grove
A Licensed General Contractor in Garden Grove is the difference between a project that passes inspection the first time and one that stalls for months in city review. In this city, that’s not a small distinction. Garden Grove’s building department sees a steady stream of permit applications for legalizing old garage conversions, adding ADUs, and updating mid-century homes to current electrical and structural code. We’ve worked through all of it. And we handle the full scope: kitchen remodels from $14,000 – $45,000, bathroom remodels from $9,000 – $28,000, and home additions from $45,000 – $130,000.
Here’s what you’re actually paying for when you hire a licensed contractor here. We manage the drawings, the city submittal, the inspections, the material procurement, and every trade on site. One contract. One schedule. One point of accountability.
Permit-Ready from Day One
We’ve pulled permits in Garden Grove enough times to know what the city wants to see on a cut sheet, a site plan, or a floor plan revision. We prepare paperwork with the city’s checklist in mind, which saves weeks compared to a homeowner submitting alone. When you work with Key Step, you’re not learning the permit process on your own kitchen project.
Written Change Orders, Not Verbal Surprises
Any contractor who’s honest will tell you a wall opened on a 1962 ranch rarely matches the original drawings. We build allowances into the contract for what we can’t see yet. When we find undersized headers, outdated wiring, or non-code framing, we stop, show you photos, and price the fix in writing. You approve before we proceed. That’s how Noel runs every project.
Residential General Contractor in Garden Grove
A Residential General Contractor in Garden Grove handles the projects that turn a dated tract home into something built for how your household actually lives. Maybe that’s a second kitchen added for aging parents. A garage converted properly, with permits, for a married child. An ADU in the backyard so the mortgage gets easier. We’ve built all of it across Garden Grove’s neighborhoods, from the tree-lined streets near West Street to the newer pockets near the 22 freeway.
Expect honest numbers. A garage conversion in Garden Grove typically runs $30,000 – $80,000 depending on whether the existing work is permitted and what needs legalizing. An ADU starts around $90,000 and can reach $220,000 for a full prefab or custom two-bedroom build. The exact number depends on the structure you’re starting with. That’s why we look before we quote.
Multigenerational Layouts
Garden Grove is one of the few Orange County cities where second kitchens, attached casitas, and converted garages are common enough to feel normal. We design for that reality. Separate entrances, independent utilities, and privacy walls without losing the main house’s flow. You’re not telling us why your family needs this. You’re telling us how you want it to function.
Prefab and ADU-Ready
We’re set up to work with Abodu and Cover prefab systems for clients who want a faster ADU path. That’s not every contractor in Garden Grove. It means we can give you a fixed-scope, factory-built option alongside a conventional stick-built quote, and you choose the one that fits your budget and timeline.
Trusted Brands We Service in Garden Grove
Your material choices should be yours, not whatever a single supplier happens to stock. That’s why Key Step Construction carries access to more than 50 vetted brands across cabinetry, countertops, roofing, windows, flooring, plumbing fixtures, and hardscaping. For Garden Grove clients tackling structural work first, we often start with products like Quikrete and Sakrete for slab repairs and foundation prep, paired with premium interior finish lines when we get to that phase. You get the right material for the job and the budget. Never a take-it-or-leave-it offer.

AfterCommon General Contractor Problems We See in Garden Grove Homes
- Unpermitted garage conversions. The garage was framed with undersized headers and drywalled without a permit. We find this constantly in the 92840 – 92844 tracts. The good news is the city has a legalization path, and we’ve walked it many times.
- Santa Ana wind stress on stucco and roofing. Hot dry winds each fall open hairline stucco cracks and expose dry rot along fascia boards. If you’re already remodeling, that’s the right time to fix the envelope, not after the drywall goes up.
- Outdated electrical panels and knob-and-tube remnants. A mid-century Garden Grove home rarely has the panel capacity for a modern kitchen or an ADU. Opening walls for a remodel triggers the electrical code upgrade. Plan for it early.
- Second kitchens added without permits. Adding a second kitchen for extended family is common in this city, but many were built without city sign-off. Before we add square footage, we verify what’s legal and what needs to be brought current.

FAQs About General Contractor in Garden Grove
Yes, we have staff who can communicate in Korean and Vietnamese during permit walkthroughs and inspection sign-offs. In Garden Grove’s Korean and Vietnamese-speaking neighborhoods, that’s not a nice-to-have. A failed inspection over a language gap costs you days of schedule. We make sure the city inspector and the homeowner both understand exactly what’s being signed. Call (855) 382-0824 if you’d like to schedule a walkthrough.
We stop work, document what we found with photos, and write a change order with the exact added scope and cost in writing. You approve before we touch it. This is the single most important reason to hire a contractor who prices honestly. On a 1962 ranch off Brookhurst in ZIP 92843, our crew opened a kitchen wall and found a garage conversion framed with undersized headers and no permits. We pulled the original drawings, brought in a structural engineer, and wrote the change order before any finish work began. The homeowner approved the added scope in writing, and we passed inspection sign-off on the first try.
Yes, in most cases we can. The city’s process requires bringing the existing work up to current code, which often means upgrading framing, electrical, and egress. We’ve done this enough to know when it’s worth the permit fees and when you’re better off starting fresh. We’ll tell you straight. Call (855) 382-0824 and we’ll walk you through the process for your specific property.
We handle it end to end. That means drawings, city submittal, plan check comments, revisions, and the on-site inspections. You’re not taking time off work to sit in the building department on Acacia Parkway. We tell you what the city will ask for, submit it clean, and manage the review cycle until you have an approved permit ready for construction. The city of Garden Grove’s plan check for additions on older tract lots usually requires a specific site plan and structural details. We know what they want before they ask.
A draw schedule is a written payment plan tied to specific milestones, not to promises. We set the draws when work is actually complete at each stage: demolition and rough-in, framing and inspections, drywall and finish, final walkthrough. You never pay for work that hasn’t happened. It protects you from contractors who front-load payments and then slow down. For a Garden Grove home addition or kitchen remodel, we’ll write the draw schedule into your contract before construction starts, and you’ll approve each draw against a visible checklist.
