What is a House Rules Addendum?

It is used by landlords and tenants varying an existing lease who want the terms recorded before work starts or money changes hands, rather than reconstructed from memory afterwards. Putting it in writing is what turns an understanding into something either side can rely on.

18 details are captured across 5 areas: parties and contact details, payment and financial terms, dates, timing and duration, property and premises, and legal protections and risk. Together they fix what the landlord owes the tenant, measured in rule addeds rather than in adjectives.

Where these agreements go wrong, it is usually an addendum that contradicts the lease it is stapled to rather than a defect in the boilerplate. Residential tenancies are tightly regulated. Deposit handling, entry notice and eviction procedure are all governed by statute, and non-compliance can cost a landlord the right to evict.

Complete the fields, read the assembled house rules addendum in the preview panel, then download it in PDF or Word format. The document follows widely used contract conventions, though it cannot account for every state rule or industry requirement — professional review is sensible before signing anything substantial.

What matters most in a house rules addendum

Both parties sign and each keeps a copy

An unsigned house rules sheet handed over at move-in usually forms no part of the tenancy.

An addendum must reference the lease

Identify the original lease by date and address, and confirm all other terms continue unchanged.

Assistance animals are not pets

Fair housing rules generally require reasonable accommodation for service and assistance animals regardless of a no-pets policy or pet fee.

When you need a house rules addendum

  • When the remedy if the added term is broken has value: Where something is still owed after the date the addendum takes effect, that obligation needs its own words. Anything expected to survive the end of the agreement has to say so.
  • When the added term needs defining: Write down what is included and what is not. A specific description is what turns an extra request into a chargeable variation rather than an argument.
  • When the date the addendum takes effect matters to someone else: Where a lender, insurer, landlord or regulator will want to see the arrangement, it needs to be written to be read by them, not only by the landlord and the tenant.
  • When the counterparty is new to you: With no track record between the parties, the written terms do the work that familiarity would otherwise do. That is exactly when precision pays for itself.
  • When something physical changes hands: Identify the item precisely and fix the moment ownership, risk and insurance responsibility transfer. Those three do not always move at the same time.
  • When the parties are in different places: Naming the governing law and the forum in advance prevents a costly preliminary fight about where any dispute is even heard.

What to include in a house rules addendum

This generator collects 18 details. Here is what each group covers and why it matters when the document is relied on.

Parties and contact details

Get these right before anything else. A dispute over the added term is unwinnable if the document names a party that does not legally exist.

Party A Name
The full legal name of the first party. Where a party is a company, name the entity rather than an individual employee.
Party A Address
The first party's address for service of notices under the agreement.
Party B Name
The full legal name of the second party bound by the agreement.
Party B Address
The second party's address for notices and correspondence.

Payment and financial terms

Tie each payment to something observable — a delivered rule added, a date, or the date the addendum takes effect — rather than to a general sense that enough has been done.

Monthly Rent
The rent amount due each period, the due date and the accepted payment methods. Ambiguity here is the single most common source of tenancy disputes.
Security Deposit
The deposit amount and the conditions for its return. Most states cap the deposit and impose a strict deadline for returning it with an itemised deduction statement.
Late Fee
The charge for overdue payment and the grace period before it applies. Keep the fee proportionate — a penalty that vastly exceeds actual loss is often unenforceable.

Dates, timing and duration

Use calendar dates, not relative triggers. "On approval" cannot be located on a calendar, which means it cannot be used to show that anyone is late.

Effective Date
The date the agreement takes effect. This can differ from the signature date, and it is the date obligations start running from.
Lease Start Date
The first day of the tenancy, when possession passes and rent begins to accrue.
Lease End Date
The final day of the fixed term, and what happens afterwards — whether the lease ends, renews or rolls month to month.
Notice Period
How much warning a party must give before ending the agreement, and how notice must be delivered to count.

Property and premises

Record the condition at the start alongside these details. The lease the addendum attaches to is what makes a later deduction or claim defensible.

Property Address
The full address of the property, including unit number, so the subject of the agreement is unambiguous.
Premises Description
What is included in the letting: rooms, parking, storage, garden and any shared areas.
Utilities Responsibility
Which utilities each party pays for, and how shared or unmetered supplies are apportioned.
Maintenance Responsibility
Who handles repairs and at what threshold. Landlords cannot usually contract out of statutory repairing obligations.
Pet Policy
Whether pets are permitted, any deposit or rent premium, and the rules. Assistance animals are generally protected regardless of a no-pets clause.
Rules and Regulations
House rules covering noise, guests, smoking, parking and shared spaces.

Legal protections and risk

These are the clauses nobody reads until something goes wrong, at which point they are the only clauses that matter.

Governing State
The state whose law governs the agreement. Choose a state connected to the parties or the work, as a wholly unconnected choice may not be respected.

Completing this house rules addendum

Planning around an addendum that contradicts the lease it is stapled to

Since this is the common failure in this kind of arrangement, decide now who absorbs it. A clause of two sentences here is worth more than a page of general good intentions.

Dates that drive obligations

Use calendar dates rather than relative triggers such as "on approval", which cannot be measured. Dates determine when obligations start, when they end, and when someone is late.

Naming the landlord and the tenant properly

Use full legal names — the registered entity, not a trading name. These are the names that must match if the document is ever relied on in a dispute or filed with a registry.

Defining the date the addendum takes effect

Say what has to be true for the date the addendum takes effect to have happened and who confirms it. An undefined completion test is the reason obligations sit open long after the work is finished.

Describing the added term

The strongest version of this house rules addendum describes the added term in terms someone outside the deal could check — quantities, rule addeds, dates and standards. Write it so a reader who was not in the room can tell whether it has been done.

Common mistakes to avoid

  1. Relying on memory instead of the lease the addendum attaches to. When a dispute starts, the question is always what was agreed at the time. The lease the addendum attaches to is the record that answers it, so attach it to the agreement rather than keeping it in an inbox.
  2. Not naming every adult occupant. Only named tenants are liable for rent. An unnamed occupant can be difficult to remove and cannot be pursued for arrears.
  3. Skipping the notice details. Say where notices go, in what form, and when they count as received. Agreements fail at this point more often than at the clauses people actually negotiate.
  4. Overlooking third-party consents. Where a landlord, lender, insurer or regulator has to agree, get that consent before the date the addendum takes effect rather than assuming it will follow.
  5. Pricing without a unit. Quote against a defined number of rule addeds. Where the price is a single figure covering an undefined quantity, every additional request looks free to the tenant and unpaid to the landlord.

How to use this house rules addendum generator

  1. Fill in the form. Complete the 18 fields above. The landlord and the tenant both need naming in full, and the added term should be described in enough detail that a stranger could tell whether it had been delivered. Nothing is sent to a server — the document is assembled in your browser.
  2. Read the preview. Check the preview against the lease the addendum attaches to. Where the two disagree, the document is the version that will be relied on, so fix it here.
  3. Download and sign. Export as PDF to sign, or as Word to keep working on it. Store the signed version somewhere both the landlord and the tenant can find it, along with the lease the addendum attaches to.

House Rules Addendum — frequently asked questions

Can a landlord charge extra for a pet?

Often yes — a pet deposit or additional monthly pet rent is permitted in many states, though some cap or prohibit it and total deposit limits still apply. The important exception is assistance and service animals: these are not pets under fair housing rules, and charging a pet fee for one is generally unlawful discrimination, as is refusing the accommodation outright.

Who should sign the house rules addendum?

The landlord and the tenant, through someone with authority to bind them. Where either is a company, that means a director or an officer with delegated authority — a signature from someone without it is a defence waiting to be raised.

How detailed does the house rules addendum need to be?

Detailed enough that someone who was not part of the conversation could read it and tell whether each side has done what it promised. That is the standard a court applies, and it is a useful test to run over your own draft before signing.

Which state's law should govern this house rules addendum?

Choose a state with a genuine connection to the parties or the subject matter — where a party is based, or where the work or property is located. A choice with no connection at all may not be respected, and for property or employment the local state's rules will often apply regardless of what the contract says.

When must the security deposit be returned?

Most states set a deadline of 14 to 30 days after the tenancy ends, along with a requirement to provide an itemised statement of any deductions. Missing that deadline can mean losing the right to deduct anything at all, and some states add a penalty on top. Document the property's condition at both move-in and move-out.

How much can the late fee be?

It should be a genuine estimate of the cost of late payment, not a punishment. Courts strike down fees that are disproportionate to actual loss, and several states cap late fees on rent specifically. A modest percentage after a stated grace period is the defensible approach.

How is notice properly given under this agreement?

Follow the notice clause exactly: use the stated method, send it to the address named in the agreement, and keep proof of delivery. Notice given informally — a text message, or an email to the wrong person — is frequently challenged, and a defective notice can leave the agreement running on.

How much notice must a landlord give to end a tenancy?

It depends on the state and the reason. Ending a month-to-month tenancy commonly requires 30 to 60 days' written notice, while ending a fixed term early usually requires a specific ground. Notice for non-payment is typically much shorter but must follow a prescribed form.
