How do you respond to a new landlord-tenant law in a state you operate in? Work through four steps, in order:

1. Confirm the rule: what changed, from when, and for which leases.

2. Map the impact: which properties, leases, documents and system settings it touches.

3. Change the work: update templates, settings, training and notices.

4. Prove it: record what changed and when, and check that it stuck.

The same four steps can serve as a starting point for any rule change, in any state.

For example: on a Monday morning, the compliance lead reads that a state where the company manages nine properties has cut its maximum security deposit, for leases signed after a date six weeks away.

Leasing is still using last year's template. The deposit amount in the system is a fixed setting. Renewals for next quarter are already being prepared. And the company manages 40 other properties in five other states, so nobody's sure who should own the response.

The law is clear enough. The response isn't.

Why does a rule change need a playbook?

Because the law is rarely the hard part. The hard part is everything that has to change because of it: templates, system settings, notices, training and the leases already signed.

The state guides show how often this trips teams up:

• Maryland: a lease template, management system or online guide that still says "two months" after the state's new deposit cap is now a live compliance error.

• California: a lease template more than 12 to 18 months old is likely missing at least one required disclosure.

A playbook makes the response the same every time, whichever rule changes.

Confirm, map, change, prove

This is the framework.

1. Confirm the rule

Before anyone changes a template, pin down five facts, from the primary source (the statute, ordinance or agency guidance) or from counsel:

• What changed, in plain words.

• The effective date.

• Which leases it applies to. This is often the trickiest part. Georgia's Safe at Home Act, for example, applies to residential leases entered into or renewed on or after July 1, 2024. Maryland's deposit cap generally applies one month's rent to new leases, while leases signed before the change stay under the old two-month limit.

• Which properties it covers, including exemptions, which can change over time. California's AB 1482 exemption for newer buildings, for example, expires as buildings age.

• Whether local rules add anything,

  since cities and counties can go further than the state.

Write these five facts down in one place. Every later step depends on them.

2. Map the impact

Work out everything the rule touches:

3. Change the work

Then make the changes, in this order:

1. Templates and notices first, so no new lease goes out under the old rule.

2. System settings, so charges, deposits and deadlines follow the new rule automatically.

3. Training, so the people using the templates and systems know what changed and why.

4. Existing leases, where the rule reaches them, at renewal or sooner if the rule requires it.

5. Resident and owner communication, where the rule requires notice, or where a change affects them.

4. Prove it

Record what changed, when, and who approved it. Then check: pull a sample of leases signed after the effective date, and confirm they follow the new rule.

Some rules also recur. Chicago, for example, requires a new Security Deposit Interest Rate Summary addendum each January, when the City Comptroller announces the rate. Put recurring updates on a calendar, so the response doesn't depend on someone remembering.

What goes in the rule change log?

Keep one record for every rule change, across every state:

Who owns each step?

What should leadership watch?

For a company operating in several states, rule changes are constant, so the question isn't whether one will arrive but how quickly the team responds. Two things are worth tracking:

• Time from announcement to compliance, for each rule change.

• Template age. How long since each state's lease template was reviewed.

And one control question: when a rule changes in any state you operate in, does everyone know who owns the response, and where the rule change log is? If the answer is "it depends who reads the news first," the next change will be handled differently from the last.

Frequently asked questions

Q1. How should a property manager respond to a new landlord-tenant law?
Confirm the rule from a primary source, map which properties, leases, documents and settings it affects, make the changes, then record what changed and check a sample of new leases to confirm it stuck.

Q2. What should be confirmed first when a rule changes?
What changed, the effective date, which leases it applies to, which properties it covers including any exemptions, and whether local rules add anything.

Q3. Does a new law apply to existing leases?
It depends on the law. Some apply only to leases signed or renewed after the effective date, while existing leases stay under the old rules until renewal. Check the law's own applicability terms.

Q4. What needs updating after a rule change?
Usually lease templates and addenda, notices, system settings such as fees, deposits and notice periods, staff training, and, where the rule requires it, resident and owner communication.

Q5. How often should lease templates be reviewed?
At least annually, and whenever a significant new rule takes effect. Templates that aren't reviewed regularly build up gaps.

Q6. Who should own the response to a rule change?
One named person, usually the compliance lead, working with counsel, operations, the system administrator and regional managers.

Q7. How do you prove a rule change was implemented?
Record what changed, when and who approved it, then review a sample of leases signed after the effective date to confirm they follow the new rule.

Q8. How do multi-state operators keep up with rule changes?
With one rule change log across every state, a named owner for each response, a calendar for recurring updates, and regular reviews of each state's templates.
