Altadena homeowners often value their properties for their space, character and connection to the surrounding community.
However, as life changes, many homes need additional flexibility. Families may need extra accommodation, professionals may need dedicated work areas, or homeowners may want to create more value from their existing land.
An Accessory Dwelling Unit provides a practical way to expand what your property can offer without the disruption of moving.
At Baumeister Construction, we design and build custom ADUs that respect the character of your property while introducing modern functionality. From initial planning through construction completion, our team provides a structured and professional building experience.
Whether you are creating a private family residence, guest accommodation, home office or future rental space, we help transform available space into something meaningful.
Many Altadena homes were built with generous outdoor areas and traditional layouts, but modern lifestyles often require more flexibility.
A growing family may need another bedroom. Elderly parents may need independent accommodation nearby. Remote work may require a dedicated office. Some homeowners simply want to make better use of unused areas around their property.
The challenge is creating additional space without losing the character and comfort of the home you already love.
