Starter Homes and ADUs Are Forcing a Meridian Code Update: What the October 20 Amendments Are About

Meridian's housing landscape continues to evolve as communities explore a wider variety of residential options, including smaller starter homes, accessory dwelling units (ADUs), and manufactured housing.

Meridian’s October 20 agenda includes something more important than a single subdivision: citywide code changes responding to new Idaho housing laws.

The public-hearing notice identifies accessory dwelling units, starter-home subdivisions, and manufactured dwellings among the topics requiring Comprehensive Plan and Unified Development Code updates.

Why this matters

When state law changes what cities may require or prohibit, local codes have to catch up. That can affect where certain housing types are allowed, what standards apply, and how future applications are reviewed.

Accessory dwelling units

Defy recently covered Meridian’s ADU transition. The practical lesson remains the same: “allowed” does not mean every lot is physically or legally ready for an ADU. Utilities, access, easements, setbacks, HOA restrictions, parking, and building-code requirements still matter.

Starter-home subdivisions

The starter-home concept matters because minimum lot size, density, and development standards can directly affect whether lower-priced new construction is feasible. The local amendment process will show how Meridian implements the new state framework.

Manufactured dwellings

The October notice also references manufactured dwellings. Buyers should distinguish manufactured housing, modular construction, and site-built homes because financing, title, appraisal, land ownership, and code treatment can differ.

What homeowners should do

• Check the final adopted code, not just hearing drafts.

• Review HOA covenants separately from city zoning.

• Verify utilities and easements before assuming an ADU fits.

• For investment analysis, model actual construction and permitting costs - not just theoretical rent.

What developers and buyers should watch

The broader issue is housing supply. Code changes can alter what can be built, but feasibility still depends on land price, infrastructure, construction cost, financing, and market demand.

Read the rules.

Defy follows these changes because they eventually affect what buyers can purchase and what owners can do with their property.

Read The Rules

Detached accessory dwelling units can offer additional living space for family members, guests, or potential rental use.
