Santa Monica is one of the most architecturally diverse cities on the Westside of Los Angeles, with residential properties spanning from 1900s craftsman bungalows in the Ocean Park neighborhood to 1950s ranch homes in Sunset Park, 1960s apartment buildings along the major corridors, and contemporary new construction throughout the city. Each era of construction used different framing techniques, load paths, and structural systems — and each requires a different engineering approach when removing load bearing walls.

Searching for a "load bearing wall engineer near me" in Santa Monica returns engineers from across greater Los Angeles, but not all firms understand the specific challenges of working within Santa Monica's regulatory environment. The City of Santa Monica operates an independent building department with plan check requirements that exceed standard Los Angeles County procedures. Historic preservation overlays in the Third Street neighborhood, Ocean Park, and portions of the Wilshire Montana area add restrictions on structural modifications. The city's mandatory soft-story retrofit ordinance has created a generation of property owners familiar with structural engineering requirements who demand thorough, permit-ready work.

AAA Engineering Design has provided structural engineering services throughout Santa Monica and Southern California for over 20 years. Our California-licensed Professional Engineers understand Santa Monica's building stock, permit requirements, and the engineering demands of wall removal in every construction type found in the city. This guide is part of our comprehensive Structural Engineering Services Guide, covering structural assessment, design, and construction support across the region. Call (949) 981-4448 to schedule your Santa Monica consultation.

Santa Monica contains approximately 52,000 housing units, with the majority built before 1980. The city's housing stock breaks down into distinct categories that each present different wall removal engineering challenges:

**Pre-1930 Craftsman and Victorian Homes.** Santa Monica's oldest neighborhoods — particularly Ocean Park, the North of Montana area, and portions of Sunset Park — contain homes with balloon-frame construction where wall studs run continuously from the foundation sill plate to the roof rafters. Removing a load bearing wall in a balloon-frame home requires understanding the continuous load path that differs fundamentally from modern platform framing. The wall does not just support the floor above — it provides lateral stability for the entire height of the structure. Our engineers design replacement systems that maintain both vertical support and lateral resistance.

**1940s-1960s Post-War Homes.** Santa Monica's largest housing segment consists of post-war ranch homes and split-levels with conventional platform framing. These homes feature load bearing walls running parallel to the roof ridge, supporting ceiling joists and sometimes carrying second-floor loads. Wall removal in these Santa Monica homes is the most common project type — homeowners want open concept kitchen-living room layouts that require removing the wall between the original rooms.

**Mid-Century Apartment Buildings.** Santa Monica's multi-unit apartment buildings from the 1950s through 1970s present the most complex wall removal scenarios. Load bearing walls in these buildings carry multiple stories of load, and removing a wall on the ground floor affects every floor above. These buildings also fall under Santa Monica's soft-story retrofit ordinance, meaning wall removal must be coordinated with seismic upgrade requirements.

**Modern Construction (1990s-Present).** Newer Santa Monica homes and condominiums use engineered framing with clearly defined load paths documented in original structural drawings. Wall removal engineering for modern Santa Monica construction benefits from existing structural documentation — but the engineering must still verify actual as-built conditions match original plans.

Santa Monica adopted a mandatory soft-story retrofit ordinance requiring seismic strengthening of vulnerable multi-unit residential buildings — typically wood-frame buildings with ground-floor parking or commercial space creating a "soft story" that collapses during earthquakes. As of 2026, the retrofit program has addressed thousands of buildings throughout Santa Monica.

When a property owner requests load bearing wall removal in a Santa Monica building that has undergone or requires soft-story retrofit, the wall removal engineering must account for the retrofit system. Removing a wall that the retrofit design relies on for lateral resistance compromises the seismic upgrade. Conversely, a wall removal project in a building that has not yet been retrofitted presents an opportunity to combine both projects — saving construction cost by performing wall removal and seismic strengthening simultaneously.

Our engineers in Santa Monica evaluate every wall removal project in the context of the building's seismic resistance system, ensuring that the open concept conversion does not create a new structural vulnerability. Learn more about our seismic retrofitting capabilities and how they integrate with remodeling projects.

Santa Monica has designated historic districts and individual landmark structures where exterior modifications — and sometimes interior structural changes — require review by the Landmarks Commission. The Third Street neighborhood, portions of Ocean Park, and individual properties throughout the city carry landmark or contributing structure designations.

Load bearing wall removal in a Santa Monica historic property requires engineering that preserves the structural character of the building. This means retaining visible structural elements where possible, using concealed beam designs that do not alter ceiling planes, maintaining original foundation systems without major modification, and documenting existing conditions before and after construction for landmark compliance.

Our structural engineers coordinate with Santa Monica's planning department when wall removal projects involve landmark properties, ensuring structural engineering solutions satisfy both building code requirements and historic preservation standards.

Identifying load bearing walls requires structural engineering analysis — not guesswork. Here is how our engineers evaluate walls in Santa Monica properties:

The primary indicator of a load bearing wall is its relationship to the framing above. Walls running perpendicular to floor joists or ceiling joists above them are carrying the weight of those framing members and transferring loads to the foundation. Walls running parallel to joists above are typically partition walls that can be removed without structural consequence — but exceptions exist when walls support point loads from beams, headers, or concentrated roof loads.

Our engineers trace the complete load path from the roof to the foundation. In Santa Monica homes with hip roofs (common in ranch-style construction), loads distribute to all four exterior walls plus interior bearing walls. In homes with gable roofs, loads concentrate on the two walls parallel to the ridge. Understanding the roof geometry tells us which interior walls carry roof loads.

A wall sitting directly above a continuous footing or thickened slab section is designed to carry loads — the foundation was specifically built to support that wall. Our structural inspection includes crawl space or below-grade investigation to identify foundation conditions beneath walls being evaluated for removal.

When available, original structural drawings from the Santa Monica building department archives confirm the intended structural system. However, 50+ years of remodeling means the current condition often differs from original plans. Our engineers verify actual conditions against any available documentation.

Some Santa Monica homes have been modified multiple times over decades. Walls that were originally load bearing have had their loads rerouted by previous remodels; walls that were originally partitions have had loads added by second-story additions. Only a PE-licensed engineer with experience in Santa Monica's construction types can make definitive determinations.

Engineering fees for load bearing wall removal in Santa Monica range from $2,000 to $8,000:

| Project Scope | Engineering Fee | Typical Total Project Cost | |---|---|---| | Single Wall Removal (residential) | $2,000–$3,500 | $8,000–$18,000 | | Multiple Wall Removal / Open Concept | $3,500–$5,500 | $15,000–$35,000 | | Wall Removal with Soft-Story Coordination | $4,500–$6,500 | $20,000–$50,000 | | Complex Multi-Story Wall Removal | $5,500–$8,000 | $25,000–$60,000+ | | Historic Property Wall Removal | $4,000–$8,000 | $20,000–$55,000 |

Total project costs include engineering, permit fees, construction, and finish work. The City of Santa Monica permit fees for structural remodeling range from $800 to $3,000 depending on project valuation. Construction costs in Santa Monica run 15% to 25% higher than the Los Angeles County average due to access constraints in dense neighborhoods, contractor demand in the premium Westside market, and material delivery challenges on narrow Santa Monica streets.

Engineering fees at the higher end apply to projects involving multiple walls, multi-story load paths, historic properties requiring preservation-sensitive design, and soft-story retrofit coordination. A straightforward single-wall removal in a 1950s Santa Monica ranch home sits at the lower end of the fee range.

Our PE-licensed engineer visits your Santa Monica property to evaluate the wall in question, identify the structural system, assess framing conditions, inspect the foundation, and measure all relevant dimensions. For Santa Monica properties, we specifically evaluate seismic resistance implications, historic preservation requirements, and soft-story retrofit status. This visit takes 1 to 2 hours for a typical residential project.

The replacement beam is the critical engineering element. Our engineers design the beam to carry all loads the removed wall supported, using the most appropriate material for the application:

**Engineered Lumber (LVL, PSL, Glulam).** For residential Santa Monica wall removals spanning up to 16 feet with moderate loads, engineered lumber beams provide cost-effective solutions. These beams can be configured as flush beams concealed within the ceiling framing depth — maintaining flat ceiling planes that Santa Monica homeowners prefer.

**Structural Steel (W-shapes, HSS).** For longer spans exceeding 16 feet, heavier loads from multi-story construction, or situations requiring minimum beam depth, structural steel beams provide superior strength-to-depth ratios. Steel beams are common in Santa Monica's mid-century homes where removing a central wall creates spans of 20 to 28 feet across combined rooms.

**Composite Systems.** Some Santa Monica projects use steel beams with wood framing saddles, allowing efficient load transfer while maintaining compatibility with the existing wood-frame structure.

The beam must transfer loads through posts to the foundation. Our engineers design post-to-beam connections, post-to-foundation connections, and any required foundation modifications. In Santa Monica homes with raised foundations, new concrete piers or spread footings are often required beneath post locations. For slab-on-grade foundations, we assess whether the existing slab thickness and reinforcement can support concentrated post loads — and design reinforcement if needed.

We produce PE-stamped structural calculations and construction drawings that include beam sizes and material specifications, post locations and sizes, connection details (beam-to-post, post-to-foundation), foundation modifications, temporary shoring requirements during construction, special inspection requirements, and construction sequence notes. These documents are formatted specifically for City of Santa Monica plan check submission, following the department's preferred drawing standards and content requirements.

The City of Santa Monica building department reviews structural plans as part of the overall building permit process. Plan check for residential wall removal takes 4 to 8 weeks. Our engineering documents are designed to achieve approval on first submittal — avoiding costly resubmission cycles that add 3 to 6 weeks each. When plan check comments are issued, we respond within 48 hours to keep your Santa Monica project on schedule.

During construction, our engineers provide observation at critical milestones — temporary shoring installation, old wall removal, beam placement, connection installation, and foundation work. This construction observation ensures the contractor builds according to our design and catches field conditions that require engineering adjustment. For Santa Monica projects, we are available for same-day site visits when construction questions arise. Explore our permit engineering services for additional information on how we support the entire permit and construction process.

The City of Santa Monica building department enforces the 2022 California Building Code (CBC) with local amendments. Wall removal projects in Santa Monica require:

**Building Permit.** Every load bearing wall removal in Santa Monica requires a building permit — no exceptions. Working without a permit violates city code, voids insurance coverage, and creates serious complications for future resale. The Santa Monica building department actively enforces permit requirements and has increased inspections of remodeling projects throughout the city.

**PE-Stamped Engineering.** Santa Monica requires Professional Engineer-stamped structural calculations and drawings for all load bearing wall removal permits. The calculations must demonstrate that the replacement beam, posts, connections, and foundation modifications safely carry all applicable loads under the current CBC including seismic demands.

**Energy Compliance.** Wall removal projects that trigger Title 24 energy compliance requirements — which occurs when the project scope exceeds certain thresholds — require energy calculations demonstrating that the remodeled space meets current energy standards. Our engineers coordinate with energy consultants when needed to ensure complete permit packages.

**Coastal Zone Review.** Santa Monica properties west of Lincoln Boulevard and south of Montana Avenue generally fall within the Coastal Zone. Wall removal projects that change the building footprint, add floor area, or modify the building envelope in the Coastal Zone require additional review. Interior wall removal that does not change the building exterior typically avoids Coastal Zone triggers.

**Historic Review.** Properties designated as landmarks or within historic districts require Landmarks Commission review before structural modifications. Our engineers prepare structural narratives explaining the engineering approach and demonstrating that the wall removal preserves the historic character of the structure.

**Soft-Story Compliance Verification.** For multi-unit Santa Monica properties, the building department verifies that wall removal does not compromise soft-story retrofit requirements. Our designs proactively address this by incorporating the retrofit system into wall removal engineering.

The most requested wall removal project in Santa Monica is removing the wall between the kitchen and living room. In 1940s through 1960s Santa Monica homes, these rooms were separated by a load bearing wall running parallel to the front of the house. Removing this wall creates a combined space of 300 to 500 square feet — transforming compartmentalized floor plans into the open concept layouts that Santa Monica buyers expect.

Engineering for this project typically involves a steel or engineered lumber beam spanning 14 to 22 feet, two to four posts transferring loads to existing or new footings, temporary shoring during construction to support the roof and ceiling loads, and connection details attaching the beam to the existing framing system.

Santa Monica homeowners frequently remove the wall between a formal dining room and an adjacent room — kitchen, family room, or living room — to create larger entertaining spaces. These projects often combine with kitchen renovation, requiring the engineer to coordinate beam placement with kitchen cabinet and appliance layouts. Our experience with residential projects throughout Santa Monica ensures that structural engineering supports the architectural vision.

Ambitious Santa Monica remodels involve removing two or more load bearing walls to create expansive open floor plans encompassing kitchen, dining, living, and family areas. Multiple wall removal requires comprehensive structural analysis because each wall carries loads that must be rerouted through the remaining structure. The cumulative effect of removing multiple walls affects the building's lateral resistance — the ability to resist wind and earthquake forces. Our engineers in Santa Monica design multi-wall removal projects with explicit attention to maintaining adequate lateral resistance.

Two-story Santa Monica homes sometimes require wall removal on the second floor to create larger master suites or open loft spaces. Second-story wall removal involves lighter loads (roof and ceiling only, no upper floors) but requires careful consideration of the floor framing below the wall. The floor must be reinforced to span the new opening without the removed wall's support.

Santa Monica's commercial properties — particularly along Main Street, Montana Avenue, and the downtown corridor — undergo frequent tenant improvement involving load bearing wall removal to create open retail, restaurant, or office spaces. Commercial wall removal in Santa Monica's older buildings requires load-bearing wall removal engineering that accounts for heavier commercial loads, longer spans, and code requirements that differ from residential projects.

AAA Engineering Design serves Santa Monica and surrounding Westside communities with localized knowledge of building stock, permit procedures, and construction conditions.

**North of Montana.** Santa Monica's premium residential neighborhood contains larger homes — 2,000 to 5,000 square feet — from the 1930s through 1950s, plus modern new construction. Wall removal projects in this area are typically higher-scope, involving multiple walls, larger beams, and premium finish requirements. Many properties in this neighborhood have been remodeled previously, requiring investigation of as-built conditions that differ from original construction.

**Wilshire Montana.** Mid-city Santa Monica with a mix of single-family homes and multi-unit buildings from the 1940s through 1960s. This neighborhood generates significant wall removal demand as homeowners modernize post-war floor plans. Multi-unit buildings in this area often fall under the soft-story retrofit ordinance.

**Sunset Park.** Santa Monica's largest residential neighborhood by area, containing 1940s through 1960s ranch homes and split-levels. Sunset Park homes are the archetype for Santa Monica wall removal — single-story ranch homes with central load bearing walls separating kitchen, dining, and living areas. Engineering is straightforward when the structure has not been previously modified.

**Ocean Park.** Santa Monica's oldest neighborhood with craftsman bungalows and early 20th-century homes, many with historic designations. Wall removal in Ocean Park requires sensitivity to historic preservation requirements and the unique structural systems of pre-1930 construction.

**Downtown Santa Monica.** Mixed commercial and residential properties including mid-rise buildings from the 1960s through 1980s. Wall removal in downtown Santa Monica buildings involves multi-story structural analysis and coordination with the building department's requirements for commercial properties.

**Venice.** Immediately south of Santa Monica, Venice shares similar housing stock and architectural character. Venice properties are permitted through the Los Angeles Department of Building and Safety (LADBS) — different procedures than Santa Monica — but the structural engineering challenges are identical. Our engineers work in both jurisdictions.

**Mar Vista.** East of Venice and south of Santa Monica, Mar Vista contains post-war homes similar to Santa Monica's Sunset Park. Wall removal engineering in Mar Vista follows the same structural principles, permitted through LADBS. Mar Vista projects typically cost 10% to 15% less than equivalent Santa Monica projects due to lower permit fees and construction costs.

**Pacific Palisades.** North of Santa Monica along the coast, Pacific Palisades contains hillside homes where wall removal intersects with slope stability considerations. Removing a load bearing wall in a Pacific Palisades hillside home requires evaluating the wall's role in resisting lateral soil pressures in addition to vertical loads. Properties affected by the 2025 Palisades Fire require structural assessment before any remodeling proceeds.

**Brentwood.** Northeast of Santa Monica, Brentwood's residential properties range from modest post-war homes to estate-scale residences. Wall removal in larger Brentwood homes involves longer spans and heavier loads, requiring steel beams and substantial foundation work. Our experience with Santa Monica and Brentwood properties spans every scale of residential construction. See our article on commercial building retrofit in West Hollywood for additional insight into structural remodeling in the greater Westside area.

**Santa Monica vs. Venice.** The structural engineering is identical — similar housing stock, similar soil conditions, similar challenges. The difference is jurisdictional: Santa Monica has its own building department, while Venice goes through LADBS. Santa Monica plan check is faster (4-8 weeks vs. 6-12 weeks for LADBS) but more thorough, requiring more detailed engineering submittals.

**Santa Monica vs. Mar Vista.** Mar Vista homes are similar to Sunset Park in Santa Monica, but construction costs are lower due to the less premium market. Engineering fees are comparable because the engineering effort is the same.

**Santa Monica vs. Pacific Palisades.** Pacific Palisades introduces hillside conditions that increase engineering complexity. Wall removal in a hillside home requires consideration of lateral earth pressures and slope stability that flat-lot Santa Monica homes do not face. Engineering fees for Palisades hillside wall removal are 20% to 40% higher than comparable Santa Monica projects.

**Santa Monica vs. Brentwood.** Brentwood homes tend to be larger than Santa Monica homes, with longer spans and heavier loads. Engineering fees for Brentwood wall removal are comparable to Santa Monica on a per-wall basis, but total project costs are higher due to larger beam sizes and more extensive foundation work.

For related structural engineering information, see our article on structural inspection engineering in Irvine for additional perspective on how structural assessment approaches vary across Southern California jurisdictions.

Total project costs for load bearing wall removal in Santa Monica range from $8,000 to $60,000+ depending on the number of walls removed, span length, structural loads, beam material, foundation modifications required, and finish work. Engineering fees ($2,000 to $8,000) represent a fraction of total cost but determine the safety, efficiency, and permit-approval of the entire project. Investing in thorough engineering from the start eliminates costly mid-construction changes.

Yes, the City of Santa Monica requires a building permit for every load bearing wall removal. The permit application must include PE-stamped structural calculations and construction drawings. Working without a permit violates the Santa Monica Municipal Code, voids homeowner's insurance coverage for related damage, and creates title issues that surface during resale. The Santa Monica building department has increased enforcement of unpermitted construction, and retroactive permit approval for structural work without original engineering is difficult and expensive.

The City of Santa Monica plan check for residential wall removal takes 4 to 8 weeks from submittal to approval. Engineering design takes 2 to 3 weeks, and construction takes 3 to 10 days for the structural work (not including finish work). Total timeline from initial consultation to completed structural construction averages 3 to 4 months. Our PE-stamped submittals are designed for first-pass approval — reducing the risk of resubmission cycles that add 3 to 6 weeks each.

Yes, load bearing walls in Santa Monica apartment buildings can be removed, but the engineering is more complex than single-family homes. Multi-story load paths, soft-story retrofit coordination, and the effect on adjacent units must be analyzed. Our engineers have completed wall removal projects in multi-unit Santa Monica buildings ranging from duplexes to 20+ unit apartment complexes. The engineering fee for multi-unit wall removal reflects the additional analysis required.

The beam type depends on span length, loads, and architectural requirements. For spans under 16 feet with moderate loads, engineered lumber beams (LVL or PSL) provide cost-effective solutions that can be concealed within ceiling framing depth. For spans exceeding 16 feet or carrying heavy multi-story loads, structural steel wide-flange beams deliver the required strength. Flush beam designs that maintain flat ceilings are preferred in Santa Monica homes where architectural appearance is a priority.

Load bearing walls contribute to a building's lateral force resistance system — the structural system that resists earthquake and wind forces. Removing a load bearing wall without compensating for the lost lateral resistance weakens the building's seismic performance. Our engineering designs explicitly address lateral resistance by adding shear panels, moment frames, or other lateral force resisting elements to replace the removed wall's contribution. Every AAA Engineering wall removal design in Santa Monica maintains or improves the building's seismic resistance.
