Essentials for any ADU floor plan

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.

Building 750 sq ft 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 you can dedicate to new living space? 3. How much you can spend on construction.

2

Select the best 750 SF house 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 for 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?

We make it easy to visualize your future house at no additional cost – both inside and outside. All of 750 square feet in detail. Even with augmented reality in your backyard.
