A rodent plan for a multi-unit building in Alameda County works across the building. UC IPM says roof rats and Norway rats are present in almost all California cities, and rats move along shared walls, risers and garages. Alameda County requires pest control businesses to register each calendar year before working in the county, and the plan is run within that rule and within the state’s licence and presence rules.
Key takeaways
- Plan the building as one system, because shared walls and risers carry rats between units.
- Confirm the species once in the reported unit, a neighbour and the common areas.
- Treat in order: the reported unit, the units on its routes, then the common areas.
- Alameda County requires business registration for each calendar year before work.
- Keep a record by unit and by common area, and give the owner a building summary.
- This guide gives no legal rule on landlord or tenant duties, and says so.
Why one unit’s problem needs a building plan
Rats move along shared walls, pipe chases and risers, and a rat removed from one unit can be replaced by one from the next. A building plan treats the route, not only the flat that made the complaint.
A pipe chase that runs up through several floors is a continuous route. A rat that enters at the ground floor can climb the chase to the upper units, and a gap around a riser gives it access to the flat beside. Treating one unit without the chase leaves the route open.
The plan therefore records every shared route. The technician looks at the risers, the wall cavities, the garage and the common storage, and marks each route that connects two or more units. The list is the basis for the order of work and for the sealing schedule.
How the species is confirmed for the building
UC IPM says the control depends on the species, and one building often holds a population using several routes. Confirming the species once across the building gives a sound basis for the plan without repeating the identification in every flat.
The identification is made in the reported unit, in one neighbouring unit and in the common areas. The evidence from each place shows whether one species or both are using the building, and the plan is written to cover what is found.
The result is recorded in the building file, so a later visit can see what was confirmed and where. Where the evidence is mixed, a monitoring period across the building is set before the sealing is finished.
What the Alameda County registration requires
Alameda County requires each pest control business to register each calendar year with the Agricultural Commissioner before it works in the county. A business working in several counties must register in each one where it works.
The registration is required of the business doing the work, and the owner can ask for it and check it with the county. A programme that starts without a current registration is not a programme the owner should accept.
The state requirements also apply. CDPR requires a pest control business licence and states that the Qualified Applicator Licence holder must be present at the location, so the programme records which holder was on each visit.
The order of work across the building
The order is the reported unit, then the neighbouring units on its routes, then the common areas, then a check of the whole route. The order stops animals moving into a space that has not yet been treated.
Working outward from the complaint means that each step closes a route before the next step opens another. The sealing of the risers and the garage joint is planned into the order, so that the animals do not find a new way in while the work is running.
The common areas are visited on the same schedule as the units, because the laundry room, the bin store and the stairwell can hold activity that moves into the flats.
What tenants are asked to do
Tenants clear the spaces the technician needs, keep food in sealed containers, do not set their own devices without advice, and report any new sign with a date and a place.
Tenants are given a written preparation list and a window for access. A missed visit delays the whole route, so the programme asks tenants to confirm the window in advance.
A tenant who sets a device before the visit should tell the technician, so the device is accounted for in the record and does not disturb the route.
The records the owner keeps
The owner keeps the building record: a page for each unit and common area, the signs found, the devices and their numbers, the sealing done and the follow-up dates. The owner also keeps the registration and the licence details for the business.
A building summary shows the trend across the units and the common areas, so the owner can see whether the activity is falling. A route that appears in several units at once is shown first, since it is the route to seal first.
The records are useful when a unit is re-let or when an inspection is requested. A turnover record that shows what was found and treated gives the owner and the next tenant a known starting point.
What this guide does not say
This guide does not state the legal duties of a landlord or a tenant in California. It does not say who pays for the work, and it does not set a price. Those questions go to the lease and to the local office that handles tenancy.
The sources for this site do not cover those duties, and the guide does not invent them. An owner with a question about responsibility should check the lease and ask the appropriate office before the work is booked.
The price for a building plan is confirmed on site. The quote should state the units, the common areas, the visit schedule and the records the owner will receive, so the owner can compare two quotes on the same scope.
How the plan starts with the first report
A tenant report is logged the day it arrives, with the unit, the room, the sign and the date. The first response is a visit within a set window, and the owner is told the plan.
A written log is the basis of a building plan. Each report is recorded with the same fields, so the owner can see patterns across the units and the seasons. Two reports from the same corridor in one month point to a route, and the plan treats them that way.
The first response is a visit, not a treatment. The technician confirms the sign, checks the unit and the neighbours on the route, and then sets the sequence. The tenant hears the plan and the date, and the owner receives the same information in writing.
Pricing a building plan without a published figure
No price for a building plan is published on this site. The quote is made on site and states its scope in writing, so an owner can compare two quotes on the same basis.
A building plan is priced on its scope: the number of units, the common areas, the visit schedule, the monitoring and the records. Two quotes that cover different units or leave out the records are not comparable, whatever the total says.
The owner should ask for the scope in writing and for the follow-up schedule. The licence holder and the county registration are given at the same time, with the Alameda County Agricultural Commissioner as the place to check the registration.
Repairs the plan recommends, and who carries them out
The plan lists each repair it recommends, such as a replaced door seal, a closed riser gap or a mesh fitted over a vent. The repair is recorded with the unit or area, and the person who is asked to carry it out is named in the report.
A repair that is inside a unit is recorded against that unit. A repair in a common area, such as a bin store door or a laundry room seal, is recorded against the building. The report makes clear which of the two it is, so the owner can see the scope of the work at a glance.
The plan does not decide who pays for a repair, and this guide does not give that rule. The report records the repair and its position, so the owner and the tenant can decide the matter under the lease and the local rules, with the facts in hand.
Communicating the plan to tenants
A tenant who understands the plan is more likely to keep to it. The notice sent to each unit explains the visit, the steps to take and the date, and it gives a contact for questions.
The notice is written in plain language and gives the window, the rooms that will be entered and the preparation that is needed. It also says what to do if a sign is seen between visits, so the tenant knows where to report it.
A short follow-up note after each visit tells the tenant what was done and what is expected next. The note is kept in the unit record, so the history of the communication is clear.
Frequently asked questions
Will the plan treat every unit at once?
Not always. The plan treats the reported unit and the units on its routes in a set order. The report states why each unit is included.
Who receives the records?
The owner or manager receives the building record. A tenant may ask for the findings for their own unit, and the plan states how that is handled.
How do I check the registration?
Ask the business for its Alameda County registration for the year, and check it with the Agricultural Commissioner. A business must be registered for each year it works in the county.
Does the plan guarantee the rats will not return?
No. It reduces the routes and the population and records the result. Activity that returns is a reason to review the plan.
Can a tenant request a copy of the building record?
A tenant may ask for the findings for their own unit. The plan states how that request is handled, and the owner decides what to share on the basis of the lease and the local rules.
What if the plan finds a repair the owner has not yet made?
The report records it with the date and the position, and sets a check on the next visit. The owner can then show that the repair was made or explain why it was not.
