Construction in Berkeley, CA
Kitchen remodeling in Berkeley typically runs $14,000-$45,000 for a full project, with smaller partial remodels starting around $9,000. What makes Berkeley different from every neighboring city is the ground itself: the Hayward Fault runs directly beneath the city, bisecting UC Berkeley’s Memorial Stadium, and Berkeley’s mandatory soft-story retrofit program plus Alquist-Priolo fault-zone rules add permitting and engineering layers that a flatland contractor in Oakland or Emeryville rarely faces. Call (470) 298-9650 for a written price before any work starts.
Why Berkeley Homes Are Different
Berkeley’s flatlands are dense with wood-frame Craftsman bungalows and two-story homes built between roughly 1905 and 1940. Most of these have unbraced cripple walls and undersized anchor bolts that predate modern seismic standards, which means any kitchen or bathroom remodel that opens a wall often exposes framing that needs retrofit work before finishes go in. The persistent marine layer near the bay accelerates moisture intrusion and wood rot in the original unprotected redwood and fir siding common on pre-war homes, so what starts as a cabinet replacement frequently becomes a sheathing and siding repair.
The Berkeley Hills sit squarely in a state-designated Very High Fire Hazard Severity Zone. Hillside projects must use fire-resistive Class A roofing, ember-resistant vents, and non-combustible siding details. Homes rebuilt after the 1991 Tunnel Fire were subject to far stricter fire-resistive requirements than the 1920s-1930s stock rebuilt after the 1923 Berkeley fire, so two houses three blocks apart in the hills can have completely different framing, foundation, and siding conditions. A contractor who only works the flatlands will not anticipate what a hillside roof or window job requires.
Our Main Berkeley Services
Berkeley homeowners call Rowan Construction Group most often about two exterior projects: fences and driveways, both of which have dedicated pages for this market.
Fence Installation in Berkeley
Wood fences in Berkeley’s flatlands contend with the same marine moisture that rots siding, so post bases set in concrete and pressure-treated or steel-reinforced posts are standard here, not upgrades. Hillside fence lines often follow steep grade changes that require stepped panels and retaining integration. We quote a flat written price before any work starts, with the fence line staked and marked before a single post hole is dug. See Fence Installation in Berkeley for full local pricing and the specific rot and slope conditions we address.

Driveway & Pavers in Berkeley
Concrete and paver driveways in Berkeley’s hills need proper subgrade compaction and drainage detailing that flatland driveways do not, especially where the Hayward Fault zone triggers soil reports. In the flatlands, older driveways often heave from tree roots and poor original sub-base prep. We pull permits when the city requires, bring the paver or concrete spec into the written quote, and document every visit with photos. See Driveway & Pavers in Berkeley for the full Berkeley price ranges and what we find under old flatland driveways.

Before
AfterKitchen Remodeling in Berkeley


Kitchen remodeling in Berkeley is a seismic job as much as a finish job. Open the wall of a 1920s Craftsman in the flatlands and you will likely find unbraced cripple walls and undersized anchor bolts, which means the remodel must include retrofit work before cabinets go in. In the hills, where the Alquist-Priolo Earthquake Fault Zone cuts through the eastern slopes, a kitchen addition or even a major remodel can trigger a geologic report and fault-setback review before permits issue. Our full Kitchen Remodeling practice includes this engineering layer in the written quote, not as a surprise change order later.
Full Kitchen Remodeling
Signs you need it
Your kitchen layout no longer works for how you cook, the cabinets are pulling from plaster walls that date to the 1920s or 1930s, or you are planning to stay in the house and want the seismic retrofit done at the same time.
What it costs in Berkeley
A full kitchen remodel in Berkeley runs $14,000-$45,000 depending on footprint, cabinet grade, and how much retrofit framing the walls need once we open them.
How we do it
We open one wall first to document existing framing, then price the retrofit scope in writing before any finishes are ordered, and no change proceeds without a signed change order.
Cabinets & Countertops
Signs you need it
Your cabinet boxes are swollen or delaminating from decades of marine-layer moisture, or the existing countertop has failed seams that let water into the substrate.
What it costs in Berkeley
Cabinet installation runs $4,000-$13,000 and countertop installation runs $2,000-$6,500, with Cambria and Caesarstone quoted at the same written price as stock laminate.
How we do it
We level the base cabinets to the actual floor condition (older Berkeley kitchens are rarely flat), set the countertop substrate, and photograph every layer before the finish goes on.
What Kitchen Remodeling Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Full kitchen remodel | $14,000-$45,000 |
| Cabinet installation | $4,000-$13,000 |
| Countertop installation | $2,000-$6,500 |
Will kitchen remodeling trigger a seismic retrofit in Berkeley?
Often yes. Berkeley’s mandatory soft-story retrofit program and the age of most flatland framing mean opening a wall frequently exposes unbraced cripple walls that the city will require you to address before closing up. We price that in writing, not as a change order.
How long does a kitchen remodel take in Berkeley?
Most full kitchen remodels in Berkeley run 4-8 weeks, with hillside fault-zone jobs adding 1-2 weeks for geologic review and permit routing. Call (470) 298-9650 for a written schedule with the quote.
Bathroom Remodeling in Berkeley


Bathroom remodeling in Berkeley usually starts with rot. The marine layer that sits over the flatlands keeps unprotected pre-war siding damp for months at a time, and by the time water shows up in a bathroom wall, the framing behind the tile is often gone. Even a small bathroom remodel in a 1920s Craftsman can expose a full wall rebuild. Our Bathroom Remodeling practice prices the framing repair and the waterproofing system in the written quote, before demo starts.
Walk-In Showers & Shower Remodeling
Signs you need it
Your shower pan has failed and water is wicking into the subfloor, or the existing tile was set on a drywall substrate that has softened and bowed.
What it costs in Berkeley
Walk-in shower installation in Berkeley runs $4,500-$12,000, with the final number driven by the condition of the framing we find after demo.
How we do it
We remove tile to the studs, document the substrate condition with photos, install a waterproofing membrane (a bonded sheet or liquid-applied system), and set the tile on a slope-to-drain mortar bed.
Tub-to-Shower Conversion
Signs you need it
The tub is original to a pre-war house, the drain has corroded, or you need a low-threshold entry and the tub footprint is the only place to put it.
What it costs in Berkeley
Tub-to-shower conversion runs $3,500-$10,000 in Berkeley, including new drain location, waterproofing, and tile.
How we do it
We pull the tub, repair or replace the drain line as needed, waterproof the entire wet area, and set a shower pan or sloped mortar bed with a code-compliant threshold.
What Bathroom Remodeling Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Full bathroom remodel | $9,000-$28,000 |
| Walk-in shower installation | $4,500-$12,000 |
| Tub-to-shower conversion | $3,500-$10,000 |
Why do Berkeley bathrooms have so much rot?
The marine layer keeps flatland siding damp for long stretches, and pre-war homes were built without the moisture barriers now required by code. By the time tile fails, the framing behind it has usually been wet for years. We photograph what we find.
Can you match a 1920s Berkeley bathroom style?
Yes. We quote period-appropriate tile profiles, clawfoot tubs, and pedestal sinks alongside modern waterproofing, and the written price includes the specific fixture brands, not a generic allowance. Call (470) 298-9650 for an exact figure.
Roofing in Berkeley


Roofing in Berkeley splits into two jobs with almost nothing in common. In the flatlands, the enemy is moisture: decades of marine-layer damp and original redwood or fir sheathing that has softened, especially on pre-war Craftsman homes where the roof was never re-decked. In the hills, the job is fire code: Berkeley’s Very High Fire Hazard Severity Zone designation requires Class A roofing, ember-resistant vents, and often non-combustible details that a flatland roof does not carry. Our Roofing practice prices both conditions in the written scope before a single shingle is ordered.
Roof Replacement & Installation
Signs you need it
Your shingles are curling or losing granules, the sheathing under the felt has visible water staining, or the roof is original to the house and nearing the end of its service life.
What it costs in Berkeley
Roof replacement in Berkeley runs $8,000-$20,000, with hillside fire-resistive requirements and re-decking pushing the number toward the top of that range.
How we do it
We strip to the sheathing, photograph the deck condition, replace any rotted or fire-damaged boards, install underlayment rated for the fire zone, and set the roof covering per the manufacturer’s written spec.
Roof Repair
Signs you need it
You have a leak that shows up during heavy rain, missing shingles after a winter storm, or the flashing around a chimney or pipe boot has separated.
What it costs in Berkeley
Roof repair in Berkeley runs $400-$1,800 for most flashing, shingle, and vent work, with skylight or cricket repairs rising within that range depending on access.
How we do it
We trace the water path to the actual penetration, not the stain inside the house, replace the failed flashing or shingle course, and photograph the repair before and after.
What Roofing Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Roof replacement | $8,000-$20,000 |
| Roof repair | $400-$1,800 |
| Metal roof installation | $15,000-$40,000 |
Does a Berkeley hillside roof need special materials?
Yes. The Berkeley Hills are in a state-designated Very High Fire Hazard Severity Zone, so the roof must be Class A fire-rated, with ember-resistant vents and non-combustible details at the eaves. We quote that as standard on hillside jobs, not as an upgrade.
Can you repair instead of replace my Berkeley roof?
If the leak is isolated and the remaining roof has service life, yes. We write the repair scope in detail, including the flashing type and underlayment, and photograph the completed work. Call (470) 298-9650 for a written repair quote.
Windows & Doors in Berkeley


Windows and doors in Berkeley fail differently by neighborhood. In the flatlands, original wood sash windows on pre-war Craftsman homes have usually lost their glazing putty and weatherstripping, and the moisture from the marine layer has begun to rot the bottom rails and sills. In the hills, the fire code drives the conversation: replacement windows and doors in the Very High Fire Hazard Severity Zone must meet ember-resistance and often non-combustible framing requirements. Our Windows & Doors practice writes the specific product, fire rating, and flashing detail into the quote before ordering.
Window Replacement
Signs you need it
Your sashes are stuck or rattling, visible daylight comes through the closed frames, or the wood sills have softened and started to crumble at the corners.
What it costs in Berkeley
Window replacement in Berkeley runs $4,500-$15,000 for a typical house, with hillside fire-rated frames and lead-safe work on pre-1978 homes pushing toward the top of that range.
How we do it
We measure each opening individually, order units sized to the actual rough openings (not nominal), remove old sashes without wrecking the interior trim, and seal and flash the perimeter per the manufacturer’s written spec.
Impact Windows & Doors
Signs you need it
You are in the hills fire zone and want the ember-resistance, or you want a single window and door package that meets the current Berkeley energy code and fire requirements at the same time.
What it costs in Berkeley
Impact window installation in Berkeley runs $8,000-$25,000, with the range driven by the number of openings and whether the frames must be non-combustible.
How we do it
We specify impact-rated glass and reinforced frames, verify the wall assembly for fire-zone compliance, and install with the same waterproofing and flashing detail as a roof penetration.
What Windows & Doors Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Window replacement | $4,500-$15,000 |
| Impact window installation | $8,000-$25,000 |
| Door installation | $1,500-$6,000 |
Do Berkeley windows need to be fire-rated?
In the hills, yes: the Very High Fire Hazard Severity Zone requires ember-resistant vents and sometimes non-combustible frames, not just tempered glass. In the flatlands, the requirement is mostly about energy code and lead-safe work on older homes.
Will new windows help with Berkeley’s marine moisture?
They stop one source of water, but the bigger issue on pre-war homes is the siding and flashing behind the trim. We open the interior, photograph the existing flashing condition, and quote any rot repair in the same written scope as the window order. Call (470) 298-9650 for a written estimate.
Home Additions & ADU in Berkeley

Home additions and ADUs in Berkeley carry a permitting burden that no flatland East Bay city matches. Any addition within the Alquist-Priolo Earthquake Fault Zone, which cuts through the eastern hills, triggers a mandatory geologic investigation and fault-setback review before the city will issue permits. Even in the flatlands, the soft-story retrofit ordinance and the age of the original foundation mean a second-story addition often requires an engineered first-floor lateral system. Our Home Additions & ADU practice budgets for the geologic report, the fault setback, and the retrofit engineering in the written quote before the project starts.
ADU Design & Permitting
Signs you need it
You have a lot in the Berkeley flatlands or hills that can carry a second unit, and you want the permit path, geologic review, and engineering priced before you commit to construction.
What it costs in Berkeley
ADU construction in Berkeley runs $90,000-$220,000 for a detached unit, with the fault-zone geologic report and hillside foundation costs pushing toward the top of that range.
How we do it
We file the site plan, bring in the third-party geologist where the fault zone requires one, get the fault-setback determination in writing, and then price the build from paper, not from a guess.
Garage Conversion ADU
Signs you need it
The existing garage sits on a slab that predates modern seismic code, the walls are unbraced, and you want to use the footprint rather than build new foundation.
What it costs in Berkeley
Garage conversion in Berkeley runs $30,000-$80,000, with the retrofit work on the original slab and walls usually the single largest variable.
How we do it
We assess the existing slab and framing, price the braced-wall retrofit and anchor work in writing, then frame the interior as conditioned living space with its own electrical and plumbing sub-panels.
What Home Additions & ADU Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| ADU construction | $90,000-$220,000 |
| Garage conversion | $30,000-$80,000 |
| Home addition | $45,000-$130,000 |
Does every Berkeley ADU need a geologic report?
No. The Alquist-Priolo Earthquake Fault Zone runs through the eastern hills, so only properties in that zone trigger a mandatory geologic investigation and fault-setback review. Flatland lots near the bay typically avoid that step, though the soft-story rules still apply to the existing structure.
How long does ADU permitting take in Berkeley?
Flatland ADU permits typically route in 4-8 months, while hillside or fault-zone projects can add 2-4 months for geologic review and fault-setback determination. We track every submission and bring the current timeline to the estimate call at (470) 298-9650.

Yes. We pull every permit the city requires, including the seismic retrofit permits under Berkeley’s soft-story ordinance and the geologic review for fault-zone projects. The permit cost and engineering fees are written into the flat price before work starts.
Anything in the Alquist-Priolo Earthquake Fault Zone, which runs through the eastern hills, triggers a mandatory geologic investigation and fault-setback review before permits issue. In the flatlands, the bigger issue is the soft-story retrofit ordinance and unbraced cripple walls in pre-war framing. We price both in writing.
