ADU Masterguide update

For over 12 months, the Masteguide has been provided at no cost to its over 600 daily users. Regrettably, the cost of maintaining the monthly server fee has become unsustainable, and as the creator of the Masteguide, I find myself unable to cover it. The monthly hosting fee I pay is $120 a month and My annual investment in upholding the site's operational continuity amounts to $1,440 a year.  When I recorded the Masterguide video, I was unaware of the extent of the financial commitment required to keep the Masterguide operational in the long term. The realization of these costs has come as a surprise, and it is with a heavy heart that I must now consider alternative options to maintain the continued availability of this valuable resource to new members as of 2/12/2023

As homeowners embark on the journey of building an ADU, they will have the flexibility to choose the contractor that best fits their needs. Our platform offers the option to book appointments with preferred ADU subcontractors, who have been vetted for their expertise, reliability, and fair pricing. Alternatively, homeowners may choose to work with a contractor of their own choosing. Either way, our goal is to provide homeowners with the resources and support they need to make informed decisions throughout the construction process.
