Santa Fe Real Estate: STR Late Fees Hit, ADU Bill Could Change Housing

Santa Fe real estate policy is shifting fast. From short-term rental enforcement to two major bills in the New Mexico legislature, homeowners and investors need to pay attention right now. Here is everything you need to know.

Santa Fe Short-Term Rental Permit Late Fees Now in Effect

If you own a short-term rental in Santa Fe and have not renewed your permit yet, you are now paying a price for waiting. As of March 15, 2026, the City of Santa Fe is assessing a $50 late fee on all STR permit renewal applications received after the deadline.

The STR permit renewal period runs from January 1 through April 15, 2026, but the city imposed the late fee threshold at March 15 to encourage early compliance. The final deadline is April 15, and missing it could mean losing your permit entirely.

Here are the key rules every STR operator in Santa Fe needs to know:

• The city caps STR permits at 1,000 for residentially zoned properties (no limit on non-residential zones)
• Only one permit per person is allowed
• The 50-foot proximity rule still applies between STR units
• A local operator must be able to respond within one hour
• Multi-unit buildings are capped at 12 permits or 25% of units, whichever applies
• All STR units require a valid business license

NM House Bill 17: ADUs Could Become Legal Statewide

One of the most significant housing bills in the New Mexico legislature right now is House Bill 17, which would require every zoning authority in the state to allow at least one accessory dwelling unit (ADU) per residential lot, regardless of lot size.

Introduced on January 26, 2026 by Representatives Andrea Romero and Heather Berghmans, HB 17 would open the door to casitas, guest houses, and backyard apartments across New Mexico. The bill also calls for multifamily housing to be permitted in all commercial districts and within a quarter mile of major public transit stops.

Key provisions of HB 17:

• One ADU per residential lot, regardless of lot size
• 5-foot side and rear setbacks for ADUs
• ADUs can be attached or detached
• No additional parking requirements beyond one space
• If passed, the law would take effect May 20, 2026 (90 days after the legislative session adjourns)

For Santa Fe, this could significantly boost housing inventory and give homeowners a new income stream. The bill is currently in the HCEDC committee and still in early stages.

NM House Bill 103: Protecting Homeowners from Property Tax Spikes

Here is one that every Santa Fe homeowner should be watching. House Bill 103 would protect the 3% annual cap on residential property valuation increases, even when the city rezones your neighborhood.

Under current law, when a zoning change occurs, the valuation cap can reset, which means homeowners can face a sudden and unexpected property tax spike through no fault of their own. HB 103 would close that loophole and keep the 3% cap in place through rezoning changes.

This is especially relevant in Santa Fe, where the city is actively updating its Land Development Code and General Plan. As neighborhoods get rezoned for higher density or mixed use, homeowners who have lived there for years could see their tax bills jump dramatically without this protection.

Track this bill at the New Mexico Legislature website.

What This Means for Santa Fe Buyers and Sellers

These policy changes create both opportunities and risks in the Santa Fe market:

• STR owners need to act now to avoid losing permits and paying penalties
• Homeowners with extra land could benefit from ADU legalization, adding a casita for rental income or family
• Long-term homeowners should support HB 103 to protect against surprise tax increases from rezoning
• Investors watching the ADU bill should start planning now for potential May 2026 changes
