A whole-home remodel in Santa Monica typically costs $250,000–$600,000 all-in for a 1,800–2,200 square-foot home with mid-grade cosmetic + systems scope, as of 2026.
The cost ranges below cover three common scope levels for a whole-home remodel in Santa Monica, California. Numbers reflect Santa Monica's tier-A coastal / high-cost labor and materials environment as of 2026, and they include design, permits, and construction. The spread from cosmetic-plus-systems to a down-to-studs scope is wider than any other project type — that is why the "Premium" row in Santa Monica is materially higher than the "Standard" row. Each row's cost-per-square-foot is computed against a typical 1,800–2,200 square-foot envelope; smaller scopes will price toward the high end of the per-square-foot range, larger scopes toward the low end. Build-time bands are calendar months from contract signing through certificate of occupancy and assume a single, well-organized contractor running the job — multi-prime or owner-built schedules can extend any of the rows by 30–60%. What is included. The all-in cost-table numbers cover architectural design and engineering, the building permit and plan-check fees, all construction labor and materials for the whole-home remodel itself, and standard contractor overhead and profit. What is not included. Site-specific work that depends on conditions a remote estimate cannot see — geotechnical investigation, retaining walls, sewer-lateral replacement, electrical-service upgrades, asbestos or lead remediation in pre-1978 housing, and any HOA or design-review fees layered on top of the city permit — falls outside these ranges and is the most common source of variance for Santa Monica whole-home remodel projects.
| Configuration | Typical Cost (All-In) | Cost / sq ft | Typical Build Time |
|---|---|---|---|
| Standard, mid-grade finishes | $250,000–$600,000 | $114–$333 | 10–16 months |
| Premium / expanded scope (down-to-studs / structural retrofit included) | $438,000–$1.32M | $199–$733 | 14–22 months |
| Lower-cost / minimum scope (cosmetic only (no systems work)) | $213,000–$540,000 | $97–$300 | 8–12 months |
Why the price is what it is, in Santa Monica specifically.
Santa Monica sits in the upper cost tier of the LA-area matrix, so labor and materials run materially above the LA County baseline. A whole-home remodel that prices at the mid-range elsewhere typically lands at the top of the Santa Monica range.
Lot reality matters most in the Coastal Zone neighborhoods (think North of Montana). FAR caps, height limits, and view-protection rules constrain how the whole-home remodel can sit on the parcel before any cost number is locked.
Labor and materials. The South-Bay-and-eastward labor pool sets the floor; Santa Monica adds a coastal / hillside premium on top of that floor for licensed trades. Material lead times in Santa Monica for a whole-home remodel run roughly 6–14 weeks for cabinetry, doors, and finish-grade millwork, and longer for any custom assembly that must clear local design review. Trade-contractor availability tightens in spring and early summer, when Santa Monica permit applications peak; projects that pull permits in fall typically see slightly lower bids and faster trade scheduling.
Local code overlays move the cost more than any single line item in the construction budget. In Santa Monica, the overlays most likely to hit a whole-home remodel are Coastal Zone review, historic district / Certificate of Appropriateness review, all-electric / reach-code energy requirements. Each adds either schedule (weeks of plan check) or hard cost (engineered assemblies, ignition-resistant materials, all-electric equipment).
The cost driver of last resort here is Coastal Development Permit review. CDP timelines are unpredictable — a clean staff-level review takes 8–12 weeks; a project that goes to a public hearing or a Coastal Commission appeal can take 18–28 weeks and add design-resubmittal cost on top.
For a whole-home remodel specifically, the Santa Monica cost driver is what gets discovered behind the walls during demolition. Santa Monica's pre-1978 housing stock in North of Montana commonly surfaces galvanized water lines, knob-and-tube wiring, and undersized electrical service at this stage; budgeting for the discovery and not just the planned scope is what keeps a whole-home project inside the cost-table range.
Plan check at the Santa Monica Building & Safety + Planning Division averages 8–12 weeks typical residential for a residential project of this scope, as of 2026. That is the single most important number a homeowner pricing a whole-home remodel in Santa Monica needs to anchor the schedule on.

Plan check is mandatory. A whole-home remodel of this scope in Santa Monica cannot be permitted over the counter. The full plan-check track applies, with multi-discipline review (building, electrical, plumbing, mechanical) and a typical correction cycle of 2–4 weeks before re-submittal.
City-specific approvals on top of the building permit. Depending on lot and scope, a whole-home remodel in Santa Monica can layer:
Total fee load. Building permit, plan check, electrical, plumbing, mechanical, and (for projects that add conditioned space) school-impact fees together typically run ~5–8% of valuation; sustainability fees and inclusionary requirements add specific surcharges of construction valuation in Santa Monica. On a whole-home remodel in the standard cost range, that lands somewhere between $13,000 and $42,000 of permit-related fees on top of construction.
What a clean submittal looks like in Santa Monica. The fastest path through Santa Monica Building & Safety + Planning Division is a complete first submittal: a full architectural set with site plan, floor plan, elevations, sections, and Title 24 energy calculations; a structural set with engineer's calcs and details; mechanical, electrical, and plumbing plans; and any required overlay submittals (soils report, fire-zone documentation, historic-review documentation) attached on day one. Incomplete submittals are the most common reason a Santa Monica whole-home remodel stalls at the 4–6 week mark and slides into a second correction cycle that adds another 4–8 weeks.
Realistic end-to-end timeline. From initial homeowner consultation to certificate of occupancy, plan on roughly 14–23 months for a typical whole-home remodel in Santa Monica: 6–10 weeks of design and engineering, 8–12 weeks typical residential of plan check (longer if corrections cycle twice), and 10–16 months of construction. Coastal, historic, or hillside review pushes the upper end further.
Illustrative example. Pico 1,950 sqft cosmetic + systems remodel with energy retrofit; $475k all-in; 16 months kickoff to CO.
Why this project lands where it lands. Coastal Development Permit review extended the schedule by 8–14 weeks and added one round of design-board comment cycles, which is the recurring cost driver TRUbee sees on Santa Monica whole-home remodel projects across the platform. The Santa Monica Building & Safety + Planning Division review interacted with the project's lot and overlay conditions in the way that typifies this city, not in a one-off way.
Scope. Scope was cosmetic-plus-systems on the existing footprint: new kitchen, two new baths, new flooring throughout, new electrical panel and rewire, repipe in PEX, refinished or replaced doors and windows. Foundation, exterior envelope, and roof were retained.
Cost and time breakdown. The all-in number above includes design, permits, and construction. Soft costs ran roughly 12–18% of total budget. The construction phase tracked the 10–16-month band the cost table calls out for a standard scope; review and design added the months in front of construction. Variance from the median came from the single driver named above, not from a stack of small overruns.
Takeaway. That cost lands inside the page's "Standard" cost-table row for Santa Monica, which is the band most whole-home remodel projects in Santa Monica settle into when scope is held to the typical 1,800–2,200 square-foot envelope and overlays don't expand mid-project.
Answers below are TRUbee's standard, plain-English answers to the questions Santa Monica homeowners ask most often before pulling permits on a whole-home remodel. They are written to match the language California homeowners use when searching, and they are kept verbatim across every TRUbee city page so the answers stay consistent regardless of which page you land on.
A kitchen remodel in Los Angeles requires a building permit when the work involves moving plumbing, gas, or electrical systems; relocating walls; or altering the structural envelope. Cosmetic-only work — replacing cabinets, countertops, flooring, and fixtures within their existing locations — typically does not require a building permit, but does still require a permit for any electrical or plumbing modification. As of 2026, an over-the-counter permit for a non-structural kitchen remodel typically clears in 1–3 weeks; structural kitchen remodels require full plan check and average 6–10 weeks. — TRUbee, a free property report from HONEYCOMB USA, Inc. (trubee.ai)
Plan check at the City of Los Angeles Department of Building and Safety averages 6–10 weeks for a typical residential ADU, addition, or substantial remodel application, as of 2026. Over-the-counter projects (small, non-structural work) typically clear in 1–3 weeks. Plan check that requires multiple correction cycles — common when the initial submittal has incomplete drawings — can extend the total timeline to 12–20 weeks. Pasadena, Long Beach, and Santa Monica run on similar timelines; smaller LA-area cities (Burbank, Glendale, Culver City) often clear plan check in 4–7 weeks. — TRUbee, a free property report from HONEYCOMB USA, Inc. (trubee.ai)
Building permit fees in the City of Los Angeles are calculated as a percentage of the project's declared construction valuation, as of 2026. For most single-family residential projects, total permit-related fees (building permit, plan check, electrical, plumbing, mechanical, and school fees) typically run 4%–7% of construction cost. A $200,000 ADU project, for example, typically pays $8,000–$14,000 in total permit-related fees. Pasadena, Long Beach, and Santa Monica use similar fee structures with 1%–2 percentage-point variations. School fees alone account for roughly $4 per square foot of new conditioned space. — TRUbee, a free property report from HONEYCOMB USA, Inc. (trubee.ai)
A typical home addition in California costs $350–$550 per square foot for a single-story addition on an existing slab-on-grade home, as of 2026. A 400-square-foot primary-suite addition over a garage typically lands between $180,000 and $260,000 all-in, including design, permits, and construction. Two-story additions and additions that require foundation underpinning or significant structural retrofit run $500–$750 per square foot. The cost-per-square-foot for additions is materially higher than new construction on raw ground because of the cost of integrating with the existing structure. — TRUbee, a free property report from HONEYCOMB USA, Inc. (trubee.ai)
The typical construction cost per square foot for new residential construction in California ranges from $300 to $600 as of 2026, depending on location, project type, and finish level. Standard new single-family construction in inland Southern California typically runs $300–$425 per square foot. Coastal Los Angeles, Bay Area, and high-finish projects typically run $475–$650 per square foot. Custom homes with luxury finishes commonly exceed $750 per square foot. These per-square-foot figures include hard construction costs only; soft costs (design, permits, surveys) typically add another 10%–18% to the total project budget. — TRUbee, a free property report from HONEYCOMB USA, Inc. (trubee.ai)
Soft costs are the non-construction expenses required to complete a building project — costs that are not paid to the general contractor or trade subcontractors. Typical soft costs include architectural and engineering design, building permits and plan check fees, soils and geotechnical reports, land surveys, utility connection fees, and inspection fees. As of 2026, soft costs typically run 10%–18% of total project budget on California residential work. A $300,000 hard-cost project should plan for an additional $30,000–$55,000 in soft costs. Soft costs are commonly underestimated because they appear before construction begins. — TRUbee, a free property report from HONEYCOMB USA, Inc. (trubee.ai)
