Common Types of Bump-Out Designs We Create
From cozy kitchen nooks to spacious primary suites, our bump-out designs expand your home in smart, seamless ways.
Kitchen Bump-Outs
Gain square footage for an island, extra cabinetry, or a cozy breakfast nook. Our plans optimize workflow, lighting, and circulation, helping you achieve a kitchen that feels open and inviting.
Bathroom Bump-Outs
Make space for a double vanity, a walk-in shower, or a luxurious soaking tub. We ensure plumbing and structural details are properly engineered for permit approval.
Primary Suite Extensions
Add square footage for a seating area, home office, or walk-in closet. Our designs enhance comfort and privacy while maintaining your home’s existing architectural harmony.
Living Room or Family Room Expansions
Open up your main living space to create better flow, brighter interiors, and room for larger furniture or built-ins. We pay close attention to proportions, natural light, and sightlines.
Why Choose a Bump-Out Addition?
Homeowners love bump-outs because they provide significant benefits without the scope of a full remodel.
Focused Space Where You Need It Most
Instead of changing your entire floor plan, a bump-out targets the exact area that needs improvement, like a narrow kitchen, a small bathroom, or a bedroom that needs more storage.
Faster and More Affordable
Bump-outs are smaller in scale, so there’s less construction time and lower costs once you’re ready to build. While we don’t perform construction, our designs help you avoid costly surprises by identifying structural and permitting requirements up front.
Adds Value and Comfort
A well-planned bump-out often recoups a high percentage of its cost through added home value. More importantly, it improves your daily life by making your most-used rooms more functional and enjoyable.

Process
The Design & Permitting Process
At Streamline Design & Permitting, our clear, transparent workflow ensures your bump-out plans move smoothly from concept to permit approval.
- Step 1
Consultation
We discuss your goals, evaluate the property, and determine the project’s feasibility. If you have a contractor, we’ll coordinate with them early to ensure the design aligns with your construction plans.
- Step 2
Site Measurement & Drafting
We then precisely measure your existing structure to produce accurate base drawings. These form the foundation for all design work and permit documentation.
- Step 3
Design Development
You’ll review floor plan options and 3D renderings showing how the bump-out will integrate with your home. We refine the design until it fits your needs perfectly.
- Step 4
Permit Drawings & Engineering
We create final architectural and structural drawings, complete energy forms, and prepare everything your city or county requires.
- Step 5
Permit Submission & Coordination
From there, our permitting specialists handle all submittals, corrections, and communication with the local building department until permits are approved.
- Step 6
Handover to Builder
Once approved, you’ll receive a full construction-ready package that includes plans, permits, and documentation. Your contractor can then start building with confidence.

FAQ
FAQ on Bump-Out Additions in San Diego
- 01
How much does it cost to add a bump-out in San Diego?
Each project is unique, with factors like size, room type, foundation work, finishes, and permitting affecting cost. We don’t offer flat pricing; instead, contact Streamline Design & Permitting for a free, tailored quote.
- 02
Do I need a permit for a bump-out in San Diego?
Yes, absolutely. Any structural addition or expansion requires a building permit in San Diego. The City’s Development Services Department (DSD) oversees all additions and remodels, and applications must be submitted electronically through their online permitting system.
Typical permit requirements include:
- Detailed construction drawings that comply with California codes and the City of San Diego building codes.
- Energy compliance documentation in accordance with Title 24 standards.
- Historical review for homes more than 45 years old.
- Coordination with the fire-rescue department, stormwater department, and other applicable departments.
- 03
What is a bump-but addition?
A bump-out addition is a small home expansion that extends an existing room outward, typically by 2 to 10 feet, to add space and improve functionality. It’s a cost-effective way to enhance areas like kitchens, bathrooms, or primary suites without building a full addition. Bump-outs can create room for an island, walk-in closet, or larger tub while blending seamlessly with your home’s design. This focused upgrade adds comfort, value, and usable square footage at a more affordable price point than a full remodel.
