Writing a Simple Residential Lease

By the Prizm P.M. team at STS Automatic LLC · Last reviewed September 18, 2026 · 9 min read

A lease is not a formality you sign on move-in day. It is the document you will reach for when something goes wrong — a late payment, a dog nobody mentioned, a deposit dispute — and the clauses you left vague are exactly the ones you will argue about. A simple, complete lease beats a long, borrowed one.

The clauses every residential lease needs

1. Parties and property. Every adult occupant's legal name, and the full address including the unit. If you rent rooms, describe the private space and the shared space.
2. Term. Start and end dates, and what happens at the end — automatic month-to-month, or expiry requiring a new lease. Say which.
3. Rent. The amount, the due date, accepted payment methods, and where payment is made. If online payment is required, say so here.
4. Late fees. Grace period, amount, and whether it repeats. Match your state's limits.
5. Security deposit. Amount, where it is held, the conditions for deductions, and the return deadline.
6. Utilities and services. Line by line — who pays electricity, gas, water, sewer, trash, internet, lawn care, snow removal. Ambiguity here causes more small disputes than anything else.
7. Maintenance responsibilities. What the tenant handles (filters, bulbs, minor clogs) versus the landlord, and how to report a problem.
8. Entry. Notice period for non-emergency entry — commonly 24 to 48 hours — and what counts as an emergency.
9. Pets. Allowed or not, species and size limits, deposit or monthly pet rent. Note that assistance animals are not pets and cannot be charged for.
10. Occupancy and guests. Who may live there and how long a guest may stay before needing to be added.
11. Subletting and assignment. Prohibited, or allowed with written consent.
12. Default and remedies. What constitutes a breach and what happens next, following your state's required notice periods.
13. Required disclosures. Lead-based paint for pre-1978 housing, plus whatever your state requires — mold, bedbug history, flood zone, utility sharing.

Clauses that cause trouble

• Blanket waivers. A clause waiving the tenant's right to habitable premises or to sue is unenforceable nearly everywhere, and its presence makes the rest of your lease look predatory.
• "Landlord may enter at any time." Almost always contrary to state law.
• Automatic forfeiture of the deposit. Deposits are held against actual, itemized damages, not forfeited by default.
• Uncapped daily late fees. Frequently struck down.
• Copy-pasted out-of-state language. A California lease used in South Carolina will contain notice periods that do not apply and omit ones that do.

Using a template safely

Templates are the right starting point — they stop you forgetting the deposit clause — but they need three passes before use: replace every placeholder, delete every clause that does not apply to your property, and check the state-specific numbers (notice periods, deposit caps, late-fee limits) against current law.

Prizm P.M. ships lease templates for the common situations — standard fixed term, month-to-month, single-family, room rental, furnished and short-term — with the money fields formatted as currency so you cannot accidentally write 1200 where you meant $1,200.00. Filling one in through the lease flow stores the terms as structured data, which is what drives rent charges, autopay and renewal reminders later.

Signing and storing

Electronic signatures are valid for residential leases in every U.S. state under the federal E-SIGN Act and state UETA equivalents. What matters is that both parties receive an identical executed copy and that you can show when it was signed. Store the lease where the tenant can view it themselves — in Prizm, tenants see their lease read-only in the portal, which quietly ends the "I never agreed to that" conversation.

Renewals and rent changes

Send renewal terms 60 to 90 days before expiry. If rent is increasing, give the notice your state requires (30, 60 or 90 days depending on where you are and the size of the increase) and put the new amount in writing. A renewal is also the moment to fix anything that did not work this year — the pet clause, the late fee, the utility split — because mid-term changes require the tenant's agreement.

This guide is general information, not legal advice. Landlord and tenant law is state and sometimes city specific; have a local attorney review your lease once before you reuse it across a portfolio.
