STR Moratoriums, Permit Caps and Grandfathering Explained
How moratoriums, permit caps, and grandfathering clauses work, why they change the value of a property, and what to check before relying on an existing permit.
Three tools cities use to limit STRs
A moratorium pauses new permits for a period while a city studies the issue or rewrites its rules. A cap sets a maximum, such as a number of permits citywide, per neighborhood, or per block, or a share of housing units. Grandfathering lets existing operators keep operating under the old rules after new ones take effect.
They are often used together: a city freezes new permits, then adopts a cap, and lets current holders continue.
Why they create a two-tier market
Once new permits are scarce, a property that already holds one can be worth more to an STR buyer than an identical house that cannot get one. That premium is only real if the permit legally survives a sale, which is a separate question covered in the guide on buying an existing STR.
Grandfathered status is also not always permanent. Some ordinances set a sunset date, require annual renewal with compliance conditions, or end grandfathering if the property changes hands or the permit lapses.
Questions to ask about any cap or freeze
Is there a waitlist, and how long is it? Is the cap a lottery, first-come, or scored? Does a permit lapse if it is unused for a period? Is there a stated end date for the moratorium, and has it been extended before? The answers are more useful than the headline "moratorium" or "cap" label.
Plan for the rules changing after you buy
Rules can tighten or loosen. Underwrite so that a bad outcome is survivable, and treat a temporary pause in your own market as a reason to keep a non-STR fallback in the model.
FAQ
- Does a moratorium affect my existing permit?
- Usually a moratorium targets new permits and existing ones continue, but the specific ordinance controls. Read it, or ask the city, to be sure about renewals.
- How long do moratoriums last?
- It varies. Some have a fixed term and others run until new rules are adopted. They can also be extended, so do not assume a set end date.
- Is grandfathering guaranteed?
- No. It is a feature of a particular ordinance, and the terms differ. Check whether it depends on ownership, continuous operation, or renewal.
