Daly City Whole-Home Remodeling & Additions
Westlake's Doelger homes and the stucco rows of Serramonte and St. Francis Heights share a compact footprint — which is exactly why a garage-conversion ADU or second-story addition in Daly City pays off. More house, same lot. We carry the whole job — design, permits, and construction — on one team, one schedule, one fixed proposal.
We Do Construction unlocks Daly City’s Doelger boxes — garage-conversion ADUs, second-story additions, and full remodels from Westlake to St. Francis Heights. Design, complete first submittals to the Daly City Building Division, and construction run on one team under a single fixed contract.
Who We Build For in Daly City
Homeowners Planning to Stay Long-Term
This is the house you’re keeping. You want it re-systemed, structurally sound, and reorganized to live the way you actually do — done once, comprehensively.
Growing Families
The house has to grow with the family — more space, a real kitchen, a better connection to the yard. We sequence the work and, where possible, keep part of the house livable.
Owners of Post-War Row & Split-Level Homes
You own a compact Daly City row house or split-level and want it opened up and modernized — light, flow, and a usable lower level — without losing the footprint that works.
What should Daly City homeowners know before adding an ADU or second story?
Daly City's housing is famously uniform — Henry Doelger's tract homes across Westlake, stucco rows through Serramonte and St. Francis Heights — and that uniformity hides real opportunity. Compact footprints reward two moves above all: converting the ground-floor garage into an ADU, and building up with a second-story addition that doubles usable space without touching the lot lines. Many homes also carry unwarranted ground-floor rooms from decades past; legalizing them during a remodel converts gray-area square footage into recorded value. At the Daly City Building Division, the schedule is set by the quality of the first submittal — complete, coordinated plans move, incomplete ones circle. A design-build contractor in Daly City earns its keep on exactly that discipline.
We Do Construction (CSLB #1096552) handles the drawings, the permits, and the build as one team on one fixed proposal. Have a garage, a downstairs room, or a roofline with potential? We'd be glad to assess it.

SIGNATURE MOMENTS
What separates a full remodel from a series of renovations.
Whole-home coordination
Plumbing, electrical, and HVAC designed together — not retrofitted room by room. Systems that work as a single home.
Live-in sequencing
We phase construction around your occupancy when possible. You don't always have to leave for a full remodel.
Single-team delivery
One GC. One point of contact. No finger-pointing between trades when something needs resolution.
ENGAGEMENT MODEL
Three phases. Every room. No handoffs.
Flat-fee at every phase. You know the total investment before work begins.
PHASE 01
Discovery
We assess your entire home — structure, systems, layout — and align the scope to how your household actually lives.
PHASE 02
Design
Integrated design across every room. Finishes, fixtures, and spatial flow resolved together so nothing conflicts.
PHASE 03
Construction
Phased execution across all spaces, coordinated by one team. You stay informed at every milestone.
Architecture & Floor Plan
Opening a tight row-house plan to light, or finishing and reworking a lower level, is where the value is on a Daly City lot.
Structure & Foundation
Post-war Daly City homes hide undersized framing and dated foundations, and the fog and slope add moisture and drainage realities. We engineer the fixes into the scope, not the surprises.
Systems: Electrical, Plumbing & HVAC
Dated panels out, modern service in; re-plumbed supply and drains; heating and ventilation sized for the whole house — done while the walls are open.
Finishes & Millwork
Rift-sawn white oak, honed stone, custom millwork — specified and detailed before demolition so the trades build to a drawing.
The Old Way
- Separate designer and contractor
- Unclear budgets and change orders
- Delays caused by poor coordination
- Limited accountability when problems arise
Our Design-Build Approach
- One integrated team from concept to completion
- Clear scope, transparent pricing, and realistic timelines
- Fewer delays and better communication
- Full responsibility for design, permits, and construction
Why Build in Daly City
Increase Property Value
On a Daly City lot, a permitted, structurally documented renovation, addition, or lower-level rework is the value move — the value is in the structure, systems, and approvals, not a surface refresh.
Improve Daily Functionality
A plan that finally fits the family, light brought in from the rear, and a house that works as one — the difference between patching and actually solving the house.
Modernize the Look and Feel
Consistent materials and detailing across every room — a house that reads as one considered project rather than a decade of piecemeal fixes.

What to Expect Building in Daly City
A full remodel or addition in Daly City is a real permit — structural, electrical, plumbing, and City of Daly City planning review for new square footage, lower-level conversions, or exterior changes. Plan on design, a review window, and several months of construction. We file the set with the City and carry it through every inspection.

Increase Property Value
A whole-house renovation done right is the biggest value move a home here can make — but the value is in the structure, the systems, and the permits, not a surface refresh.

FAQ
Yes — a remodel, addition, or build means a structural permit set with the City of Daly City, plus planning review for new square footage or exterior changes. We file it, manage the review, and carry the job through every inspection.
Typically several months of design, a review window with the City of Daly City, and several months of construction — longer for a down-to-studs remodel or a large addition. We give you the real schedule in feasibility.
For phased or partial-scope work we can often keep part of the house livable. A full down-to-studs remodel is safer and faster with the house empty.
It depends on square footage, how much structure and systems work is involved, and the finish level. We price it in feasibility against a real scope, then hold it in a fixed proposal.
Both. We are design-build — architecture, engineering, permitting through the City of Daly City, and construction on one team and one contract.
Yes — we engineer foundation, shear, and seismic upgrades into the scope so the work is sound, not just refinished.
Yes — Daly City and the surrounding communities. Each project files with the jurisdiction that governs it.
Yes. After feasibility and a defined scope we issue one fixed proposal covering design, permits, and construction.
How much does a full home remodel cost in San Francisco?
A full home remodel in San Francisco typically runs $350,000–$900,000+ in 2026 — roughly $300–$600 per square foot, and higher when structural or seismic work is involved. The range reflects SF labor rates, the realities of pre-1978 housing stock, and the finish level of a design-build home. We Do Construction (CSLB #1096552) delivers whole-home remodels across San Francisco on a single fixed-price design-build contract.
| Tier | Typical SF range (2026) | Scope |
|---|---|---|
| Finishes-forward | $350,000–$500,000 | Existing layout kept, new kitchen and baths, finishes, systems refresh |
| Full reconfiguration | $500,000–$750,000 | New floor plan, relocated plumbing and electrical, Title 24 systems |
| Structural / addition-grade | $750,000–$900,000+ | Walls out, steel and seismic upgrades, custom millwork throughout |

What permits does a full home remodel require in San Francisco?
A whole-home remodel touching layout, structure, plumbing, electrical, or mechanical systems requires a building permit from the SF Department of Building Inspection (DBI), and work that changes the building envelope or use also goes through SF Planning. Full-scope and structural permits run 2–4+ months in plan review, and additions 3–6 months; historic districts north of California Street add design review. Pre-1978 homes also trigger lead and asbestos protocols. As a licensed SF general contractor (CSLB #1096552), We Do Construction files and manages the entire DBI and Planning process in-house.
