Some Democratic lawmakers in Colorado are pushing a proposal that would allow homeowners to split their lots to make room for smaller, lower-cost houses. The bill, HB 1308, aims to open the door to first-time homeownership, but has drawn opposition from cities across the Front Range who argue it undermines local land-use decisions.

Why it matters

The proposal is part of a broader effort by state lawmakers to address Colorado's affordable housing crisis, which has priced many first-time buyers out of the market. However, cities are concerned the state-level mandate could erode their ability to control local development and zoning.

The details

HB 1308 would permit lot-splitting, provided the new parcels are at least 1,200 square feet. Homeowners with a mortgage would need lender approval. The bill is limited to municipalities with over 1,000 residents within a metropolitan planning organization region, primarily benefiting Front Range communities. While supported by realtors, homebuilders, and some cities like Fort Collins, the measure faces opposition from Aurora, Colorado Springs, Denver and the Colorado Municipal League.

  • The bill cleared the state House on March 24, 2026 in a 39-26 vote.
  • HB 1308 is now awaiting action in the state Senate.

What they’re saying

“Coloradans expect and deserve a voice in decisions that directly impact where they live.”

— Bev Staples, Representing the Colorado Municipal League

“It doesn't mean that a local government always has to say yes, because, like with other land‑use bills, there are good reasons why you should say no.”

— Andrew Boesenecker, Democratic Speaker Pro Tem

What’s next

The state Senate will now consider HB 1308 after its passage in the House.

The takeaway

This proposal highlights the ongoing tension between state efforts to boost affordable housing and local governments' desire to maintain control over land use and development decisions in their communities.
