Construction in Alhambra, CA
Kitchen remodeling in Alhambra, CA typically runs $14,000-$45,000 for a full project, with most of the cost driven by what the walls reveal once they’re opened: lathe-and-plaster over ungrounded wiring, galvanized supply lines, and framing that predates modern code. We’re Rowan Construction Group, and we’ve spent 18 years writing flat prices for work like this before the first tool comes out. If you’re planning a remodel, addition, or ADU on one of Alhambra’s 1920s-1950s bungalow lots, call (470) 298-9650 and we’ll walk you through what the numbers look like for your specific street and square footage.
Why Alhambra Homes Are Different
Alhambra’s residential blocks are dominated by California bungalows, Craftsman cottages, and Spanish Colonial Revival homes built between 1920 and 1955, most sitting on post-and-pier or shallow concrete perimeter foundations that were never engineered for a second story. When we open a wall in an Alhambra kitchen or bathroom, what we typically find is lath-and-plaster over knob-and-tube or early Romex, not drywall over grounded modern wiring, and the galvanized supply lines have usually been corroding from the inside for fifty years. That means the renovation budget in Alhambra almost always includes remediation work that a newer home in Monterey Park or Rosemead might skip entirely.
There’s also a demographic factor here that shapes more jobs than anywhere else in the San Gabriel Valley. Alhambra has one of the most concentrated Chinese-American communities in the United States, and that drives an outsized demand for room additions, garage conversions, and ADUs on compact bungalow lots where three generations often share one address. The Alhambra permit counter processes a high volume of ADU and junior-ADU applications, and experienced local contractors know the city’s specific setback rules for detached ADUs on pre-1950 lots, plus a sewer lateral upgrade requirement that neighboring cities frequently don’t trigger.
Finally, the climate works against sloppy scheduling. Alhambra sits on the inland San Gabriel Valley floor, where summer afternoons reach 95-105°F, routinely ten to fifteen degrees hotter than coastal LA just ten miles west. Concrete pours and adhesive-set anchoring have to go in during early morning hours or the material cures too fast and fails. The alluvial fan soils left by the historic San Gabriel River also vary in compaction within short distances, which is why we recommend geotechnical review before any new foundation or significant addition.
Our Main Alhambra Services
Alhambra homeowners call us most about two exterior projects: fence installation on compact lots that need real property-line precision, and driveway and paver work where heat and soil both demand careful base preparation. Here’s what each involves locally.
Fence Installation in Alhambra
Alhambra’s bungalow lots are tight, with property lines that often run within inches of a neighbor’s home, so fence work here is as much about accurate boundary marking as it is about setting posts. Many homes built before 1955 still have the original wooden fence lines, and rot at the post base is common after seven decades of winter rain and summer heat. We quote Fence Installation in Alhambra as a flat written price with the full scope documented before crews arrive, including any retaining considerations on sloped lots.

Driveway & Pavers in Alhambra
Alhambra’s alluvial fan soils mean that a paver or concrete driveway is only as good as the base underneath it, and the summer heat accelerates curing failures on poorly scheduled pours. We see older driveways here cracked along the expansion joints and sinking at the edges where the original 1950s sub-base was never compacted to modern standards. For Driveway & Pavers in Alhambra, we schedule early-morning concrete work, document the soil compaction at each layer, and price the job in writing before any material arrives.

AfterKitchen Remodeling in Alhambra


A full kitchen remodel in Alhambra typically runs $14,000-$45,000, and the range exists because two identical-looking 1948 bungalows can hide completely different conditions: one might have modern Romex behind the plaster, the other has ungrounded knob-and-tube from the original build that must be replaced before any permitted electrical work passes inspection. We’ve opened enough Alhambra kitchen walls to know the remediation line item is not a surprise, it’s the norm. When you work with us, Kitchen Remodeling is scoped with every condition documented, every brand named, and a flat written price delivered before the first cabinet comes out.
Full Kitchen Remodeling
Signs you need it
Your Alhambra kitchen has single-wall framing, dated plumbing, or a layout that no longer works for a multigenerational household that cooks daily.
What it costs in Alhambra
A full kitchen remodel in Alhambra runs $14,000-$45,000, with the spread driven by whether the original knob-and-tube or early Romex wiring must be replaced and how much foundation work the compact bungalow lot requires.
How we do it
We demo to the studs, document what’s behind the lath-and-plaster, replace all substandard wiring and galvanized supply lines, then rebuild the kitchen to a written plan with every cabinetry and countertop brand named in the scope.
Cabinets & Countertops
Signs you need it
Your Alhambra home’s original 1940s or 1950s built-in cabinetry has sagging shelves, delaminating veneer, or door hinges that no longer align, and the counters show deep wear at the sink.
What it costs in Alhambra
Cabinet installation in Alhambra runs $4,000-$13,000 and countertop installation $2,000-$6,500, depending on whether you’re keeping the existing layout or moving plumbing and electrical.
How we do it
We measure every cabinet run to the wall, order from vetted brands like KraftMaid and Wellborn, and install after the walls are verified plumb and the countertop substrate is level.
Backsplash, Tile & Flooring
Signs you need it
The original tile is cracked along the grout lines, the flooring has water damage near the sink, or the backsplash has failed entirely behind the range.
What it costs in Alhambra
Backsplash installation runs $800-$2,500 in Alhambra, with flooring and tile work priced per square foot once we see the subfloor condition under the 1950s original.
How we do it
We level the substrate, repair any water-damaged subfloor, and set tile on a membrane suited to Alhambra’s interior temperature swings so the grout does not crack in the first summer.
What Kitchen Remodeling Costs in Alhambra
| Item | Typical range in Alhambra |
|---|---|
| Full Kitchen Remodel | $14,000-$45,000 |
| Cabinet Installation | $4,000-$13,000 |
| Countertop Installation | $2,000-$6,500 |
How long does a kitchen remodel take in Alhambra?
A full kitchen remodel in Alhambra typically runs six to ten weeks, with the schedule affected by permit review timing and any electrical remediation uncovered during demo. We document every day of work in the photo record.
Will my Alhambra kitchen remodel need wiring replacement?
Most homes built in Alhambra before 1960 still carry knob-and-tube or early ungrounded Romex, and any permitted kitchen work requires bringing that to current code. We inspect and quote it before demo starts. Call (470) 298-9650 for a specific number.
Bathroom Remodeling in Alhambra


A bathroom remodel in Alhambra runs $9,000-$28,000 for a full project, and the cost is shaped by what is behind the original 1940s-1950s tile: many of these bathrooms were built directly on the floor joists with no waterproof membrane, so the framing is often water-damaged around the tub. We scope Bathroom Remodeling with that reality in the written price from day one, not as a change order halfway through.
Walk-In Showers & Shower Remodeling
Signs you need it
The existing tub-shower has chronic grout failure, water staining on the ceiling below, or the curb and threshold are soft underfoot.
What it costs in Alhambra
A walk-in shower installation in Alhambra runs $4,500-$12,000, with the final number set by the condition of the floor framing once the original tile comes out.
How we do it
We remove the tile, inspect the joists and subfloor, replace any water-damaged framing, then install a full waterproof membrane before any tile is set.
Tub-to-Shower Conversion
Signs you need it
The cast-iron tub is too deep for older family members to safely step over, a common concern in Alhambra’s multigenerational households.
What it costs in Alhambra
A tub-to-shower conversion in Alhambra runs $3,500-$10,000, including the plumbing reconfiguration from tub waste to shower waste and updated drain sizing.
How we do it
We remove the tub, rework the drain and supply lines to code, then build a curbless or low-curb shower with a leak-tested membrane and documented photo record.
What Bathroom Remodeling Costs in Alhambra
| Item | Typical range in Alhambra |
|---|---|
| Full Bathroom Remodel | $9,000-$28,000 |
| Walk-In Shower Installation | $4,500-$12,000 |
| Tub-to-Shower Conversion | $3,500-$10,000 |
Are the original Alhambra bathroom walls waterproof?
Most original 1940s-1950s Alhambra bathrooms were built without a waterproof membrane behind the wall tile, so water intrusion over decades has typically damaged the framing. We check and rebuild before retiling.
How far in advance should I schedule a bathroom remodel in Alhambra?
We typically schedule Alhambra bathroom remodels two to four weeks out, with the permit drawing and plan review taking the first portion. Call (470) 298-9650 and we’ll give you a written timeline.
Roofing in Alhambra


Roof replacement in Alhambra runs $8,000-$20,000, and the decisive local factor is the layered composition shingles on original 1920s-1950s roofs: many have two or even three layers that must be stripped to the deck before any new underlayment goes down. Summer rooftop temperatures in Alhambra routinely exceed 120°F, which is why we schedule tear-off and installation for early mornings. Roofing work here is quoted with the full layer count documented and the written price covering everything to the clean deck.
Roof Replacement & Installation
Signs you need it
Your Alhambra roof has multiple shingle layers, granule loss in the gutters, or any decking softness indicating decades of moisture exposure.
What it costs in Alhambra
Roof replacement in Alhambra runs $8,000-$20,000, with the range driven by square footage, number of layers stripped, and whether any decking or fascia repair is required.
How we do it
We strip every existing layer to the deck, document the condition board by board, replace damaged decking, and install new underlayment and shingles from vetted brands like GAF and Owens Corning.
Roof Repair
Signs you need it
You have a localized leak, missing shingles after a Santa Ana wind event, or cracked flashing around a vent or chimney on an older Alhambra roof.
What it costs in Alhambra
Roof repair in Alhambra runs $400-$1,800, depending on the number of affected areas and whether any decking replacement is needed beneath the damaged section.
How we do it
We locate the exact point of water entry, document the affected area in photos, then replace the damaged materials and refit the flashing to a watertight condition.
What Roofing Costs in Alhambra
| Item | Typical range in Alhambra |
|---|---|
| Roof Replacement | $8,000-$20,000 |
| Roof Repair | $400-$1,800 |
| Metal Roof Installation | $15,000-$40,000 |
Do Alhambra roofs need different materials than coastal LA roofs?
Not different materials, but different scheduling: the San Gabriel Valley’s hotter summers mean we install adhesive-set underlayments and sealants in early morning to prevent premature curing failure. The substrate detail is the same high standard.
Can you match the original tile on my Alhambra Spanish Colonial?
Yes, tile roof repair runs $600-$2,500 in Alhambra, and we source period-appropriate replacement tile through our supplier network rather than making a visible patch. Call (470) 298-9650 and we’ll assess your roof.
Windows & Doors in Alhambra


Window replacement in Alhambra runs $4,500-$15,000, and what makes local jobs distinct is the framing: original windows on 1920s-1950s homes were set directly into the stud openings without modern flashing or insulation, so every retrofit is a full-frame, not a pocket insert. Our Windows & Doors work is quoted with the removal of the old sash and track, proper pan flashing, and the specific brand and glass package named in the written scope.
Window Replacement
Signs you need it
The original double-hung windows are painted shut, the sashes rattle, or the single-pane glass means the house cannot hold temperature during Alhambra’s 100°F summer afternoons.
What it costs in Alhambra
Window replacement in Alhambra runs $4,500-$15,000, with the total set by the number of openings and whether the original 1950s frames require any structural correction.
How we do it
We remove the old sash and track entirely, inspect the rough opening, reframe as needed, then set the new window on pan flashing with the exterior trimmed and sealed.
Door Installation
Signs you need it
The original front door is warped or has separated at the stiles, or the threshold no longer seals against the occasional winter rain.
What it costs in Alhambra
Door installation in Alhambra is quoted per opening, with the final number set by the existing jamb condition and whether any termite-damaged framing must be replaced.
How we do it
We remove the old door and jamb, inspect the rough opening and subfloor for dry rot or termite damage, then set the new pre-hung unit square and trim it out.
What Windows & Doors Costs in Alhambra
| Item | Typical range in Alhambra |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
| Door Installation | Quoted per opening |
Are original Alhambra windows worth restoring instead of replacing?
For most 1920s-1950s Alhambra homes, restoration is not cost-effective once you factor in air sealing and insulation. Replacement delivers better performance for the same or lower long-term cost.
Do I need a permit to replace windows in Alhambra?
Yes, Alhambra requires permits for window replacement when the opening size changes or any structural framing is altered. We pull permits and document every inspection. Call (470) 298-9650 for the specifics on your street.
Home Additions & ADU in Alhambra

Home additions in Alhambra run $45,000-$130,000 and ADU construction $90,000-$220,000, with the city’s dense infill reality and multigenerational household patterns driving far more of these projects than in neighboring San Gabriel Valley cities. The foundation work is the critical cost variable: Alhambra’s alluvial fan soils, varying compaction, and older sewer laterals mean every addition or ADU starts with geotechnical review and a lateral condition check. Home Additions & ADU is quoted after we see the lot, the setback envelope, and the sewer scope results.
Garage Conversion ADU
Signs you need it
You need separate living quarters for aging parents or adult children on an Alhambra bungalow lot where the garage is the only buildable footprint.
What it costs in Alhambra
A garage conversion ADU in Alhambra runs $30,000-$80,000, with the final cost depending on whether the existing slab can be reused or must be re-poured to meet current foundation code.
How we do it
We evaluate the existing garage slab and framing, document which walls can be salvaged, then reframe, insulate, and finish the ADU to full code with its own kitchen and bath.
ADU Design & Permitting
Signs you need it
You are considering an ADU on your Alhambra lot but are unsure whether the pre-1950 setback rules, sewer lateral condition, or lot dimensions will allow it.
What it costs in Alhambra
ADU design and permitting in Alhambra is scoped as part of the full construction estimate, with plan drawings, structural calculations, and the permit package all delivered before construction begins.
How we do it
We survey the lot, run the title report, check the sewer lateral by camera, then produce drawings that meet Alhambra’s specific ADU setback and height rules before the permit application goes in.
What Home Additions & ADU Costs in Alhambra
| Item | Typical range in Alhambra |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion ADU | $30,000-$80,000 |
Does Alhambra require an owner-occupancy rule for ADUs?
Current Alhambra municipal code does not impose an owner-occupancy requirement for ADUs, but homeowners should verify the current ordinance at the planning counter before filing. We research this for every project we quote.
Will my Alhambra ADU require a sewer lateral upgrade?
Frequently yes. Alhambra’s older sewer laterals, often original clay pipe from the 1920s-1950s, commonly trigger a lateral replacement or lining requirement when an ADU adds a second dwelling connection. We camera the line before pricing.
