What the city actually requires, what happens if your property gets flagged, and the two halves of staying clear of trouble: the yard the city can see, and the holes it can't.
Boise's new rodent ordinance (City Code § 4-1-2) went on the books in October 2026. November is education month. Enforcement starts December 1, 2026 — after that, properties that don't meet the standard can get a deadline, and if the work isn't done, the city can have it done and bill the owner.
The good news: most of the ordinance is a weekend checklist. The part most homeowners can't do with a free Saturday is the sealing — and that's the part that actually keeps rats out. Here's the whole thing in plain language.
Boise's rodent rules aren't only about having rats — they cover the conditions that attract and shelter them: accessible food, harborage, and openings that let rodents into structures. That means a property can draw the city's attention before anyone sees a single rat, based on fallen fruit, open trash, debris, or a neighbor's complaint.
It starts with a letter, not a fine: notice of the conditions, and a window to correct them. Ignore it, and the city can step in, abate the problem itself, and bill the property owner for the work. The practical difference between a letter that goes away and a bill that doesn't is documentation — being able to show, with dates, what you did and when.
The yard is what the city sees. The holes are what the rats use. Walk the house slowly and look for any opening a rat could use — they need about a half inch; mice need a quarter inch.
Sealing has to be done with materials rats can't chew through — steel mesh, metal flashing, mortar, hardware cloth. Foam and caulk alone are a snack, not a seal.
The ordinance splits it: occupants handle sanitation, food, and waste; owners handle structural deficiencies and harborage — the sealing, the vents, the conditions built into the property. Renting doesn't move the structural duty off the owner, and a lease can't hand it to the city. If you're a renter, the checklist half is yours and the sealing half is your landlord's — this page is a good thing to send them. If you're a tenant who got a letter, send it to your landlord right away; if you're a landlord, that letter is exactly what a compliance folder answers.
On the homepage we keep it short: our sealing work is guaranteed. Here is the full breakdown, in plain language, so there is no confusion about what that covers.

What it doesn't cover:
In short: we guarantee our sealing work. We don't guarantee that rodents will never cause a problem anywhere else, and we don't clean up after them.
We're not a pest control company. We don't spray and leave. We prevent — we seal the openings and fix the conditions — and every job leaves behind a paper trail:
That folder is yours to keep. If a compliance letter or a citation ever shows up, you're not scrambling to prove you handled your property — you hand the city the folder, with dates. Most homeowners facing the ordinance have nothing in writing. Our customers do.
That's what the $49 exterior inspection is for. We walk the outside of the house the way a compliance officer would — attractants, harborage, and every access point — and you get the findings in writing, with photos. The $49 is credited in full toward any sealing work you have us do, and your compliance folder starts the day we walk your property.
