300 Sq Ft Tiny House & ADU Plans

300 Sq Ft ADU, Studio & Tiny Home Plans

A 300 sq ft home may be compact, but with the right design it can feel open, functional, and inviting. Whether you’re envisioning a small ADU for rental income, a backyard studio, or a minimalist tiny house, well-planned layouts maximize comfort, storage, and natural light without wasting a single square foot.

What Fits Into 300 Square Feet?

Even with limited space, a 300 sq ft plan can support full-time living when thoughtfully arranged. Common features include:

  • Flexible living/sleeping area or convertible multipurpose space.
  • Compact kitchen with efficient appliance layout.
  • Full bathroom — often with walk-in shower or wet bath.
  • Lofted or built-in storage to make use of vertical space.
  • High ceilings & large windows for openness and light.
  • Connection to outdoor areas through patios, decks, or sliding doors.

Ataman Studio designs prioritize circulation, proportion, and energy efficiency so that small homes feel larger than their footprint suggests.

Plan Types We Offer

Our 300 sq ft plans are buildable, permit-ready, and tailored to California’s residential codes:

  • Tiny homes — on wheels or permanent foundations.
  • Backyard studios for creative work, guest space, or rentals.
  • ADUs (Accessory Dwelling Units) — detached units that meet state size limits for small-scale housing.
  • Micro homes with modern, rustic, or transitional styles.
  • Accessible layouts for mobility needs or aging in place.

Every plan is engineered to comply with Title 24 energy codes and can be adapted for setbacks, slopes, or narrow parcels.

Designed for California Properties

Unlike generic house plan catalogs, Ataman Studio develops designs that reflect real-world permitting. Our 300 sq ft ADU plans account for:

  • Local zoning and setback requirements.
  • Energy compliance and sustainability standards.
  • Site-specific adjustments for topography and utilities.
  • Constructability and approval processes in California cities.

You’re not just buying drawings — you’re investing in a plan that’s ready to submit and build.
