Utah Eyes Statewide Rule Allowing Smaller Homes in Every City

A Third Attempt at Statewide Lot-Size Reform

Utah is taking another run at overriding local zoning to force smaller homes into the market, as first reported by Building Salt Lake. Steve Waldrip, Gov. Spencer Cox's senior housing strategy advisor, told the ULI Utah Housing Summit that his office wants a bill for the 2026 session allowing homes between 1,000 and 1,400 square feet to be built by-right, regardless of a city's own zoning code, if a lot meets certain criteria.

This isn't the first swing. Rep. Ray Ward's House Bill 88 (statewide ADUs) and House Bill 90 (6,000-square-foot lots) both died in committee in 2025 despite Waldrip's testimony. What's different now is the political framing. Waldrip says the group of people who believe there's a housing problem "has grown dramatically," and he links that shift directly to legislators' own adult children moving back home. That's a harder argument for a city council to wave off than an abstract affordability statistic.

The Real Fight Is Opt-In Versus By-Right

The bill's substance is still being negotiated, and the gap between stakeholders matters more than the headline. Wasatch Advocates for Livable Communities policy manager Lauren Cole told Building Salt Lake her understanding is that the proposal would create an opt-in "starter home overlay zone" — not a statewide mandate on minimum lot sizes. Cities would choose whether to participate.

Cole's group would rather see something closer to Idaho's Senate Bill 1352, signed this year, which bars cities over 10,000 residents from requiring minimum lot sizes above 1,500 square feet for detached starter homes in qualifying subdivisions. Her argument: an incentive model "doesn't match the scale of Utah's housing shortage," and cities may simply decline to opt in. That tension between mandatory reform and local control killed HB88 and HB90 last session, and it's the single variable that will determine whether this bill produces real inventory or another symbolic overlay district few cities adopt.

Pre-Approved Plans Are the Part Builders Should Watch

The overlooked piece of this proposal is the pre-approved floor plan component. Waldrip's pitch to cities is a trade: give builders certainty on an approved plan, approved lot size, and approved location, and skip the months of council hearings and legal fees that currently attach to nearly every new home. "It kind of checks all the boxes," Waldrip told Building Salt Lake, describing the bipartisan appetite for the idea.

For builders and developers, that trade is worth real money. Entitlement risk and carrying costs on small-lot projects are often what kill a starter-home pro forma before it starts. If a builder can point to a state-sanctioned plan set and know the timeline in advance, underwriting gets simpler and land that was previously too marginal to pencil for infill starts to look viable. We're already fielding calls at Team Utah Commercial (801-898-8810) from owners of odd-shaped or undersized parcels asking whether this changes what their land is worth — the honest answer right now is that it depends entirely on whether the final bill lands as opt-in or by-right.

Infill Land Along the Wasatch Front Is the Asset to Track

Cole made a point during the summit that landowners should sit with: Salt Lake County is approaching buildout capacity under current zoning, which means infill is the primary path left for established cities to add housing without pushing into foothills or farmland. She framed it bluntly — "lot size policy is water policy too" — tying zoning directly to Great Salt Lake conservation.

That framing raises the stakes for any parcel inside existing city limits currently zoned for one home per lot. If a statewide overlay or by-right standard passes, small infill lots near job centers and transit could see the fastest repricing of any product type in the state, well ahead of new subdivision land on the fringe. The Legislature convenes in January 2026. Watch whether Ward and ULCT reach agreement before bill text drops, because the negotiated language between now and then will decide whether this becomes the tool builders actually use or the third version that stalls in committee.
