2 Bedroom ADU Floor Plans

150+ Floor Plans From 700 to 1,200 Sq Ft.

Pick a plan that fits your family needs and property.

Two bedroom ADU floor plans come in many layouts. Most prefabs will be I shaped or L shaped. But you can maximize your backyard potential with a custom shape.

The best ADU Floor Plan meets all family needs and reflects the shape of your main house and property line. Your new ADU should look like it has always been there. It should also maximize the space – take as much of your backyard as you are willing to dedicate to the new living area.

What are the benefits of 2 bedroom ADU floor plans?

Technically, the house this size won’t even be considered a tiny home. It may fit either a young family with a kid or a retiree (or two). One of the bedrooms can double up as a home office or guest house.

What ADU floor plan will make the most of your backyard?

Hint: the ones that fit your backyard like a lost piece of a puzzle.

Case study: 2 bedroom ADU Floor Plan

One of our 2 bedroom ADU plans: 1000 sq ft with one bathroom

Requirements

A family is moving an aging parent closer to home, and try to accommodate a guest suite for a wheelchair bound relative.

  • Wheelchair access
  • Vaulted ceilings in the living room
  • Deck facing the creek with a see through fireplace
  • Matching the look and style of main house

Restrictions

The location of this ADU was restricted from all 4 sides sides:

1. Property line 2. Main house 3. Creek  4. Public Utility Easement 

 

In addition to all that, it was in WUI zone and had to be built fire resistant. In this project, we had only one win: there were two hydrants on both sides of the property within the required 400 ft distance.

Result

A bigger bathroom accommodates the necessary area for a wheelchair turnaround, has both a shower and a tub, plus houses the laundry. 

The living room has vaulted ceilings (though the general contractor in charge may blacklist us for this design feature). The fireplace is surrounded by two windows, with the nearby exit to the deck  facing the creek

The initial design had walk in closets in both bedrooms. However the homeowners decided to have a bigger one in the primary bedroom and have the smaller size guest room.

Essentials for any of our 2 bedroom ADU floor plans

Insulation

Type of insulation is called out in your Title 24 report provided by your energy consultant or HERS rater.

Kitchen Appliances

All ADU floor plans should show sink, cooktop, hood and fridge. These items are essential for anyone living permanently in the ADU.

Fire and CO2 Alarm

Smoke and carbon monoxide alarms are required on the wall or ceiling outside of each sleeping area. 

HVAC and Ventilation

Ductless mini splits are an accepted way to heat and cool your ADU. Energy Recovery Ventilators are an energy-efficient way to maintain indoor air quality.

Water Heater (Heat Pump)

As California goes all electric, think about the sizing of your pump – it depends on the number of people living in the ADU.

Address Numbers

ADUs are often required to have two sets of a minimum of 4 inch high house numbers – with one on ADU and an extra that is seen from the public road.

2 bedroom ADU sounds like a challenge?

We make it easy to get started

1

Create property site plan

Let us answer three questions together: 1. How big can you build? 2. How much of a backyard can you dedicate to new living space? 3. How much can you afford to spend on construction.

2

Select the best 2 bedroom ADU floor plan

We do not like to invent wheels or bicycles. Let us get started with the plan that fits most of your requirements and then tweak it to make it shine in your backyard.

3

Assign the team

The success of a construction project hinges on how well the team communicates. You have a contractor you like? Bring her on board. We are happy to support you with the design, engineering and construction – when needed.

4

Gather Necessary Documents

Let us start with the best information available. What do you already have? Title report. Floor plan or site plan of your main house. Survey. Soil report. All these documents are a great foundation for your future successful construction project. Pun intended.

5

Compile the permit plan set

The number of pages in your plan set can differ from 8 to 140 (no kidding). It all depends on property specifics and city (or county) requirements. The better prepared your first submission is, the faster you get your permits. 

6

Respond to Plan Checker comments

Do you know that the most frequent reason it takes such a long time to pull permits is the number of weeks that passed between the day the city had given plan check comments and the day your team responded to them?

Three pillars of a well designed home

What you need to consider for your 2 bedroom ADU?

Foundation

From traditional slab and pier options to hybrid foundations that use helical screw piles – the final choice needs to be evaluated on the basis of backyard access, feasibility, budget and house designs.

Performance

California is going all electric. This means your water heater will be electric. So will your HVAC heat pump and cooktop. You will be required to put some solar panels on the roof as well. All this needs a 200A + electric panel. 

Natural Light

We love indoor-outdoor seamless flow and having lots of natural light. It often comes at the expense of energy efficiency. You can compensate for it with better quality windows with a lower U factor.
