We balance style, natural light, and privacy with floor plans that maximize living space and storage, and we specify durable finishes to reduce maintenance over time.

Comprehensive ADU Building Permit Assistance

From preparing the permit set to coordinating plan check comments, our ADU Building Permit Services streamline your path to approval.

Our team addresses fire, structural, and Title 24 requirements while managing submittals, revisions, and permit fee guidance so you can move from design to construction with confidence.

We keep communication clear and ensure each permit milestone is met on schedule.

Permitting Unpermitted ADUs

If you need to legalize an existing space or convert an unpermitted structure, our Permitting Unpermitted ADU Services can help. We perform as-built documentation, code analysis, and remediation plans to bring the unit to current standards.

We resolve safety, egress, and utility issues and then resubmit for the appropriate permit and inspection path to secure final sign-off.

Professional Construction Management

LADU's ADU Construction Services connect you with one of our licensed ADU construction partners to deliver quality ADU construction.

We monitor schedule, budget, and finish quality, coordinate utility trenching and connections, and manage punch-list completion for a smooth, predictable project closeout.

ADU Design Options

LADU provides diverse ADU styles perfectly suited to Pasadena's architectural landscape.

Spanish Style ADU

For a Spanish-style ADU, we echo Pasadena's Mediterranean heritage with clay tile accents, arched entries, smooth stucco, and warm-toned finishes that harmonize with your main home.

Our Spanish-style ADUs blend curb appeal with modern performance for a timeless accessory dwelling unit.

Studio ADU

Ideal for compact lots and efficient living space, a studio ADU delivers a smart open-plan layout, streamlined storage, and natural light, perfect for a guest suite or minimalist lifestyle. We tailor the finish package, from durable laminates to elevated hardwoods, to your budget.

Cottage ADU

A cottage ADU offers storybook charm with practical comforts such as gable roofs, cozy porches, and well-proportioned interiors. Whether you intend it for a family member or long-term rental, we design for comfort, privacy, and enduring value.

2 Bedroom ADU

A 2 bedroom ADU supports small families or shared living while maintaining privacy between sleeping areas. It's a flexible choice for multigenerational households or longer-term rental opportunities.

3 Bedroom ADU

For larger needs, a 3 bedroom ADU can serve as a spacious accessory dwelling unit with generous storage, a full kitchen, and upgraded finishes for long-term comfort. This size ADU is often a strong performer for rental income.

Garage ADU

Transform existing square footage by converting a garage into a code-compliant garage ADU. We assess structure, slab, and insulation and then convert the space into a polished, climate-controlled dwelling with careful attention to sound control and finish quality.

Junior ADU

A junior ADU (JADU) leverages internal space within the primary residence for an efficient studio or one-bed suite with a kitchenette. It's a cost-conscious path to add living space without expanding your footprint.

Key ADU Regulations in Pasadena

Understanding local ADU rules ensures you plan accurately from the start. Depending on your zone and lot configuration, Pasadena supports a variety of ADUs.

• Maximum size up to 1,200 square feet
• State-exempt ADUs at 800 square feet
• Height restrictions of 16 feet
• Flexible parking requirements

Many sites qualify for an 800 square feet state-exempt option; larger footprints may be possible if site constraints and coverage permit. We help evaluate parking relief, setbacks, and utility strategies to align with current standards.

We also guide homeowners through site planning, which includes situating your ADU in the backyard for privacy, designing pathways and lighting, and coordinating landscaping.

With an accessory dwelling unit on your property, you can accommodate a family member, create a focused home office, or establish a steady rental opportunity.

Our process clarifies budget and finish selections early so you can make informed decisions with fewer changes mid-project.

Neighborhood Considerations

LADU ensures your ADU respects Pasadena's architectural character by:

• Matching local architectural styles.
• Maintaining appropriate scale and proportions.
• Preserving neighborhood aesthetic integrity.

We carefully review your property's context, including block patterns, setbacks, and any applicable overlay or conservation zones, to design an ADU that looks and feels at home.

If your site sits behind the primary house, we orient windows and entries for privacy and quiet enjoyment while maximizing sunlight and ventilation. Our approach balances contemporary performance with neighborhood character.
