New Regulations Being Considered

In 2023, the City of Lafayette expanded the use of accessory dwelling units (ADUs) citywide. Previously, ADUs were only permitted in the Old Town Residential zoning district. The City is now considering further updates to eliminate parking requirements for ADUs, remove certain design standards, and refine where ADUs are allowed.

Draft regulations are located in the document library to the right.

What is an Accessory Dwelling Unit?

An Accessory Dwelling Unit (or "ADU"), is a small independent living space on the same lot as a primary residence. It typically includes a kitchen and bathroom. These are sometimes referred to as mother-in-law suites or carriage houses. Both detached and attached/interior ADUs are allowed in most areas that allow single-unit, detached homes. See the handout in the documents library for more information about current regulations.

What is the City thinking? You sold us out by waiving water fees to gain developers. You expect residents to make up the shortfall for your greediness. Now you want to change the ADU rules
for "affordable housing". We moved to this area because of the quality of neighborhood life. The lots here are small. The last thing we need are 20 foot high ADU's, five feet from the property line. If the City needs that housing so badly, give up some undeveloped property and develop that. If I wanted to live in an urban setting, I would have done so. This is a terrible idea.

I live in Lafayette Park on .2 acres. I grew up in Boulder County but am the only person in my family who has not been forced out due to price. My brother lives with us as he tries to start a business in Lafayette, but I'm getting ready to start a family and will need to have the use of my bedroom. An ADU would allow me to help my brother now, and help my parents in the next few years as they are aging and need help close by. An ADU would allow them to return to their home area, but without one, I may be forced to leave mine in the coming years. Being able to make use of my own property to help my family would lift a tremendous burden! Thank you for considering.

I think expanding the building of ADU's in Old Town is long overdue especially South of Emma. I own a property I'd love to develop further. It seems unfair that 2 blocks away ADU's are going up in every alley all over town. I would not even consider renting it out....I need it for family!

Please kindly address impact based on potential short term rentals, rent cost and impact on cost of housing.
