ADU Center

Building Accessory Dwelling Units is now easier and more affordable thanks to GLADUR – your Green and Livable Accessory Dwelling Unit Resource, a product of HEART of San Mateo County.

Made possible by an award for climate protection funding by the Bay Area Air Quality Management District, HEART provides designs for green, all-electric detached ADUs that can be downloaded by the public at no cost.

Saving you design costs and months of design development time, HEART’s investment allows homeowners to focus their expenditures on improved energy efficiency and renewable energy options to reduce greenhouse gas emissions and energy bills.

Please note we require all visitors to complete a User Agreement in order to view and use the GLADUR Construction Documents, at no cost to you.

Pre-Reviewed Cities / County

To further make it easier to build green ADUs, HEART is partnering with local jurisdictions to pre-review the designs so as to reduce approval times for homeowners and to streamline the permitting process.

GLADUR Handbook

Download the Handbook
(PDF, 25 MB)

HEART’s comprehensive green ADU handbook provides key information and resources, highlighting how environmentally friendly ADUs improve the living experience for occupants while also contributing to the collective mission in lowering greenhouse gas emissions.

Homeowners will learn about sustainable features, building materials, and other innovative ways to design and build green ADUs.

This handbook also provides homeowners with background information on environmental and livability issues for their consideration.

While homeowners can use the handbook to guide their usage and even customization of the GLADUR designs, this handbook can be used independently of the GLADUR designs by all homeowners.
