Why Key Step Construction Is Aliso Viejo’s Preferred General Contractor Company
Aliso Viejo homeowners deal with a construction landscape most contractors in neighboring cities never see. This master-planned city was built out between the late 1980s and early 2000s, so nearly every job we take on here is remodel, addition, or repair work on 1990s-era planned-community housing. That means HOA design review boards, architectural submittal packets, and slope conditions on terraced lots are part of the daily reality. General contractor work is different here, and we’ve built our process around it.
Noel Garrity leads every project with a single point of accountability. You won’t juggle subcontractors or chase down material approvals. We file the HOA submittal, pull the city permit, schedule the trades, and stand behind the finished work. When an Aliso Viejo homeowner calls us about a kitchen remodel or a room addition, they’re getting a contractor who has already navigated dozens of design-review boards in this city’s villages.

General Contractor Services in Aliso Viejo
General Contractor Services in Aliso Viejo means coordinating every trade, every material decision, and every approval under one contract. Most of our work here is kitchen and bathroom remodels, room additions, and exterior replacements on homes built in the 1990s. A typical kitchen remodel in Aliso Viejo runs $14,000 – $45,000 depending on cabinet line, countertop material, and whether walls are moving. Bathroom remodels land between $9,000 and $28,000. These jobs usually require HOA interior approval when plumbing or structural changes are involved, plus city permits for any electrical, plumbing, or load-bearing work.
Kitchen and Bath Remodels
We plan kitchen and bathroom remodels around the HOA review clock from day one. Material choices like KraftMaid cabinetry and Cambria or Silestone countertops give you real selection without vendor hand-holding. We file the submittal packet early, so demo doesn’t start until the design board signs off.

Room Additions and ADUs
Room additions in Aliso Viejo typically range from $45,000 to $130,000. ADU construction runs $90,000 to $220,000. Both require the full architectural review sequence: HOA first, then city permit. We’ve partnered with leading prefab ADU manufacturers like Abodu, Dvele, Boxabl, Mighty Buildings, and Plant Prefab to give Aliso Viejo homeowners faster, cleaner options that still clear local review.

Construction Company in Aliso Viejo
As a Construction Company, Key Step Construction operates as a full-scope general contractor serving Aliso Viejo from roof to foundation. That means exterior work like roofing, siding, windows, fencing, and hardscaping sits under the same contract as interior remodeling. It’s the main reason homeowners call us instead of patching together three or four specialty crews. No coordination chaos, no finger-pointing when a detail slips.
Exterior Replacements and Roofing
Aliso Viejo’s original clay tile roofs are now hitting replacement age across the city’s villages. Roof replacement here runs $8,000 – $20,000, and window replacement lands between $4,500 and $15,000. HOA approval often dictates materials, profile, and color, whether that’s a standing seam metal roof or replacement vinyl windows. We build to the brand’s spec and to the HOA’s spec.
Hardscaping and Site Work
Paver patios, retaining walls, and drainage corrections are common on Aliso Viejo’s terraced lots. We work with Belgard, Unilock, Tremron, and Techo-Bloc products that carry their own product warranties. When a sloped lot needs a retaining wall rebuilt before a patio can go in, we handle that under the same contract, not as a handoff.
Trusted Brands We Service in Aliso Viejo
We stock and install materials from Master Halco, Ameristar, and Jerith across Aliso Viejo fencing and hardscape jobs. These are brands built for the dry, sun-exposed conditions this city sees during Santa Ana wind season. Because we have local access to parts and panels, we can turn around fence repairs and replacements faster than a contractor who has to special-order from outside the county. Plan it once, build it right.
Common General Contractor Problems We See in Aliso Viejo Homes
- HOA review delays. Many homeowners jump straight to demolition before architectural approval comes through. That triggers stop-work orders and design-review fines. We file the submittal packet before demo day, every time.
- Slope and drainage failures. Aliso Viejo’s terraced grading means even small additions can fail inspection if drainage isn’t engineered correctly. We’ve corrected plenty of water intrusion problems that started with a contractor who ignored the grade.
- Post-tension slab complications. These 1990s-era foundations cannot be cut or trenched without an engineer’s plan. DIY or under-informed contractors hit tendons and cause structural damage. Our General Contractor team brings in the engineer before any slab work begins.
- Incomplete HOA submittals. A packet missing color samples, material specs, or an accurate site plan gets kicked back. The review clock restarts. We’ve refined our submittal process through dozens of Aliso Viejo design review boards so your project doesn’t sit half-finished waiting on a committee.

FAQs About General Contractor in Aliso Viejo
HOA architectural review in Aliso Viejo typically adds 30 – 60 days to a project that requires exterior changes, structural work, or visible additions. This review happens before the city will accept a permit application. We file the submittal packet as soon as the design is finalized and schedule trades around the approval date, so work doesn’t start until the board signs off. Call (855) 382-0824 for a realistic timeline on your specific project.
Most Aliso Viejo villages require exterior materials and colors to match the original Mediterranean or Spanish-revival palette: stucco in earth tones, clay tile or specified composition roofing, and window frames that match the neighboring homes. Substitutions like a different roof material or paint color usually require a variance request. We build the submittal with samples and spec sheets that match the original design intent, which clears review faster than a creative departure.
Yes, if the remodel touches plumbing, electrical, or structural elements, you need a city permit even for a small bathroom. If you’re only replacing a vanity, countertop, or light fixture without moving plumbing or wiring, a permit may not be required. Your HOA may also require interior approval if the work changes plumbing routing or wall configurations. Call (855) 382-0824 for a free evaluation of your specific scope.
We start with a geotechnical or structural engineer to assess the slope and existing drainage before any foundation or addition work begins. On terraced lots, we typically install retaining walls, French drains, or regraded swales as part of the addition scope, not as an afterthought. Post-tension slab work requires an engineer’s plan before cutting or trenching. This is standard practice on Aliso Viejo’s graded villages, and it’s why our additions pass inspection on the first try.
For purely cosmetic interior work like painting, cabinet replacement, or countertop installation, you can often start before HOA approval as long as no structural, plumbing, or electrical changes are involved. But for anything that touches plumbing routing, load-bearing walls, or exterior appearance, wait for HOA sign-off. Working early can trigger fines and stop-work orders. We’ll tell you exactly where your project falls before any tool touches the wall. Call (855) 382-0824 to talk through your scope.
Home additions in Aliso Viejo typically run $45,000 – $130,000, which is roughly in line with Laguna Hills and Irvine but often slightly higher than flat-lot cities because of slope engineering and HOA submittal requirements. The added costs come from retaining wall work, drainage design, and the architectural review packet, not from higher material prices. Your estimate will include those line items so you can see exactly where the money goes.
