Expanding Beverly Hills Homes Since 2013

For over a decade, we've been helping Beverly Hills homeowners navigate the complex process of adding space to their properties. Whether it's a room addition for a growing family, an ADU for rental income, or navigating SB9 for lot splitting, our contractors understand that Beverly Hills has unique requirements that go beyond standard construction.


From hillside additions in Benedict Canyon requiring specialized engineering to ADUs in the Flats needing historical compliance, our Beverly Hills contractors have managed expansions across every neighborhood. What makes them different? They understand that in Beverly Hills, even the foundation work needs planning board approval.

Why Beverly Hills Additions Are Different

Let us share something contractors from outside the area often underestimate: adding space in Beverly Hills involves considerations you won't find elsewhere. The zoning restrictions, view preservation requirements, hillside development ordinances, and historical preservation guidelines create a unique regulatory environment.

Local Contractor Insight

The biggest mistake I see homeowners make is assuming their lot can accommodate the addition they want. Beverly Hills has strict rules about setbacks, lot coverage, height restrictions, and view corridors. Our contractors start every project with a thorough zoning analysis to determine what's actually possible before anyone invests in design work.

What Our Beverly Hills Addition Contractors Handle

Our network of local contractors specializes in all types of home expansions. Here's their typical scope:

Single Room Additions

Adding bedrooms, offices, family rooms, or specialty spaces with seamless integration.

Full-Story Additions

Adding complete second or third stories with proper structural engineering.

ADU Construction

Building accessory dwelling units that comply with Beverly Hills' specific ADU regulations.

SB9 Projects

Navigating Senate Bill 9 for lot splits and duplex construction in eligible areas.

The Beverly Hills Addition Process

Feasibility Analysis & Zoning Review

Our contractors start by analyzing what's actually possible on your property. They review Beverly Hills zoning maps, calculate allowable lot coverage, check setback requirements, and identify any view corridor restrictions. This step saves homeowners from investing in designs that can't be approved.

Design Development with Regulations

Once feasibility is established, our contractors work with architects to develop designs that not only meet your needs but also comply with Beverly Hills regulations. They consider everything from roof pitch requirements to material compatibility with existing structures.

Permitting & Approvals Process

This is where Beverly Hills expertise becomes critical. Additions often require not just building permits but also planning commission review, especially for larger projects or those in historic districts. Our contractors navigate this process efficiently, knowing exactly what documentation each department requires.

Construction with Integration Focus

The construction phase focuses on seamless integration with your existing home. Our contractors match materials, align rooflines, and ensure the addition looks like it was always part of the original structure a particularly important consideration in Beverly Hills where property values depend on cohesive design.

Final Inspections & Systems Integration

Before considering an addition complete, our contractors ensure all systems are properly integrated. They test electrical connections, HVAC integration, plumbing systems, and ensure the addition meets Beverly Hills' energy efficiency requirements.

Beverly Hills ADU Regulations & Requirements

Accessory Dwelling Units in Beverly Hills come with specific requirements. Here's what our contractors navigate regularly:

Requirement Beverly Hills Standard Key Considerations
Maximum Size 1,200 sq ft or 50% of main house Whichever is less; includes attached garages in calculation
Height Limits 16 feet maximum May be lower in hillside areas or specific zones
Setback Requirements 4 feet from side/rear More restrictive than state minimums in some cases
Parking 1 space required May be waived if near transit; tandem parking often allowed
Owner Occupancy Required for 3 years Must be recorded on title; affects rental potential
Real-World Beverly Hills Experience

We recently worked with homeowners in the Flats who wanted to add an ADU above their detached garage. The challenge was that the garage was historic, and Beverly Hills has specific requirements for additions to historic structures. Our contractors worked with the preservation board to design an addition that met modern needs while preserving the garage's historical character. The result was a beautiful ADU that generated rental income while maintaining the property's historical integrity. That's the kind of nuanced understanding our Beverly Hills contractors bring to every project.

SB9 Construction in Beverly Hills

Senate Bill 9 has created new opportunities for Beverly Hills homeowners, but it comes with specific requirements:

Lot Split Eligibility

Not all Beverly Hills lots qualify. Minimum lot size, width, and other factors determine eligibility.

Unit Size Limitations

Each unit must be at least 800 square feet with specific dimensional requirements.

Owner Occupancy Requirements

One of the units must be owner-occupied for at least three years after construction.

Utility Considerations

Separate utility meters and services are typically required for each unit.

Hillside Addition Considerations

For Beverly Hills homes in the canyons or hillside areas, additions require special attention:

  • Geotechnical Engineering: Soil stability analysis is required for most hillside projects
  • Retaining Walls: Often needed and require engineering approval
  • Access Requirements: Fire department access must be maintained or improved
  • View Preservation: Additions cannot block protected view corridors
  • Seismic Considerations: Hillside structures require special seismic design

Cost Considerations for Beverly Hills Additions

Let's have an honest conversation about addition costs in Beverly Hills. The regulatory environment and quality expectations create unique cost considerations.

  • Room Additions: Typically $400-$700 per square foot depending on finishes and complexity
  • Second Story Additions: Usually $500-$800 per square foot including structural work
  • ADU Construction: Generally $350-$600 per square foot for complete units
  • SB9 Projects: Can range from $800,000-$1.5M+ for complete lot split and construction
  • Factors Affecting Cost: Site access, engineering requirements, Beverly Hills permit fees, material selections
Budgeting Reality Check

Based on our decade of experience, we recommend budgeting 25-30% more for Beverly Hills additions than you might for similar projects in surrounding areas. The combination of stricter regulations, higher permit fees, more complex engineering requirements, and Beverly Hills quality expectations all contribute to higher costs. Our contractors provide transparent estimates that account for these unique factors from the beginning.

Frequently Asked Questions About Beverly Hills Additions

How long does the Beverly Hills approval process take for additions?

For simple additions not requiring discretionary review, plan on 3-4 months for design and permitting. For projects requiring planning commission review (common for larger additions or those in historic districts), plan on 6-9 months. ADUs typically take 4-6 months, while SB9 projects can take 9-12 months from start to permit issuance.

Can I add a second story to my Beverly Hills home?

Possibly, but it depends on several factors: your home's existing foundation capacity, hillside development regulations if applicable, height restrictions in your zone, and view preservation requirements. Our contractors start with a structural assessment and zoning review to determine feasibility before proceeding with design work.

What are the rental income possibilities for Beverly Hills ADUs?

Beverly Hills ADUs can generate significant rental income, typically $3,000-$6,000 per month depending on size, finishes, and location. However, there's a 3-year owner occupancy requirement, and some neighborhoods have additional restrictions. Our contractors can help you understand both the income potential and the regulatory constraints.

How do additions affect my property taxes in Beverly Hills?

Under Proposition 13, your property tax base increases only on the new construction value, not your entire property value. The county assessor will reassess the added square footage at current market rates. Our contractors provide the documentation you'll need for proper assessment, and we often recommend consulting with a tax professional about potential implications.

What's the difference between an addition and an ADU in Beverly Hills?

An addition expands your primary residence, while an ADU is a separate, self-contained living unit. ADUs have their own kitchen, bathroom, and living space, and they're subject to different regulations regarding size, parking, and owner occupancy. The choice depends on your goals: more space for your family versus creating a rental unit or separate living quarters.
