OWNER-BUILDER 
ADU ROUGH PRICELIST

20X20 garage conversion

I know every homeowner is looking for the best price possible to build their ADU. One way to save homeowners time is by eliminating the process of meeting with multiple contractors to get an Estimate. This is why I have created a rough estimate price list from the contractors on our site. Yes, the cost of plumbing and electrical is high however we are trying to connect homeowners with experienced ADU Subcontractors.

OPTIONS

Some contractors on our list may not have the best price possible for some sections of work therefore, by taking a look at their rough price, you as the homeowner can decide to book an appointment or keep looking for a better deal. When homeowners work with our suggested contractors their ADU Experience makes the only difference 

ADU's 
ARE EXPENCIVE

The average cost to build an ADU with a company is between $120,000 - $180,000 for a 20X20 garage conversion with average finishes. By working with Subcontractors directly, the cost to build an ADU could be $74,000. Homeowners will save an average of 37% ($44,000) of the construction cost. Homeowners could save an additional 6-10% if they get dirty and do some basic work on their ADU.

SUBCONTRACTORS WITH 
ADU EXPERIANCE

A different approach, 

The advantage the contractors on our list bring to the table is their vast ADU experience. By working with an experience ADU Subcontractor the process will be like driving on autopilot. The homeowner can just relax and wait for the work to pass the inspection. 

BUILD DIFFERENT

With the ADU Rough Pricelist and the Masterguide, I hope homeowners can build their ADU and save money.
