Free Improvements and Modifications Lease Addendum Template

An Improvements and Modifications Lease Addendum is an attachment to a lease. It records which changes a tenant may make to the rental, and on what terms.

Most leases bar tenants from altering the property at all. However, this document creates a written exception for one specific project. Nobody has to rewrite the lease itself.

The scope can be modest or substantial. Mounting a television, painting a bedroom, or swapping cabinet hardware all qualify. So do bigger jobs, such as adding a raised garden bed or installing bathroom grab bars. In every case, two questions decide the terms: what exactly is approved, and how should the unit look when the tenant leaves?

Requests usually surface once a tenant has settled in and wants the space to fit their life better.

Frequent examples:

• A renter who wants to paint over a builder-grade white wall.
• A family adding safety gates, shelving, or a wall-mounted television.
• A tenant asking for accessibility changes such as a handheld shower or a ramp.
• A long-term renter offering to replace worn fixtures at their own expense.
• A gardener hoping to build raised beds or add a fence panel in the yard.

Owners gain from saying yes in writing rather than yes by text message. Furthermore, a documented approval keeps a well-meant improvement from turning into a deposit dispute two years later. Meanwhile, the tenant gets certainty about what they may actually do.

Accessibility requests deserve their own note. They follow a different path than a cosmetic change, so handle them separately from a paint request.

A complete Improvements and Modifications Lease Addendum describes the work, the approval, and the end state. Cover each of these in the guided form.

The Lease This Addendum Modifies

Reference the property address and the date the lease was signed, along with each named tenant.

Description of the Work

Describe exactly what changes, including rooms, surfaces, materials, and colors. Precision in this section is what makes the approval enforceable.

Approval and Conditions

State that the owner approves this particular project. Then list any conditions, such as using a licensed contractor or working within set hours.

Timeline

Give a start date and a completion date, plus what happens if the work stalls partway through.

Cost Responsibility

Say who pays for materials, labor, and permits. Also note whether the tenant earns any rent credit or reimbursement.

Restoration at Move-Out

People skip this section and later regret it. Specify whether each change stays, comes out, or returns to its original condition. Then name who handles that work.

Damage and Insurance

Note who carries responsibility if the project damages the property. Similarly, decide whether proof of contractor insurance is required first.

Signatures and Start Date

The tenant and landlord both sign and date; nothing else in the lease changes.

Two questions drive nearly every disagreement about tenant alterations: was this approved, and who returns it to normal?

Settle approval first. Written approval naming the specific project beats a general permission slip. After all, a renter told they could paint may reasonably assume that covered the ceiling too.

Then settle restoration. Generally, three outcomes work:

• The change stays and becomes part of the property.
• The tenant removes it and repairs the surface before moving out.
• The owner removes it and deducts a pre-agreed amount.

Pick one per item and write it down. Additionally, photograph the area before and after the work. Then the final walkthrough compares the same conditions both parties agreed to.

Money deserves its own sentence. Decide whether an improvement the tenant paid for belongs to them at move-out, or joins the property the moment it goes in. Fixtures attached to walls or floors raise that question first.

Projects touching wiring, plumbing, gas, or structural elements deserve extra care. In those cases, require licensed work and proof of any permit the local building department expects. Likewise, ask for the contractor’s certificate of insurance before day one.

Requirements vary by property and by whoever owns or manages it. Therefore, confirm the basics before work begins.

Ask these questions:

• Does the building have rules through a homeowners association or condo board?
• Does the local building department require a permit for this kind of change?
• Does the owner’s insurance policy limit tenant-performed work?
• If the request involves accessibility, what process does the owner follow for those requests?

Check your state’s official website for landlord-tenant guidance, then confirm anything property-specific with the owner, manager, or association. A local building office can answer permit questions directly.

An addendum records an agreement. However, it does not override building codes, association rules, or a right either party already holds. For larger projects, or where an accessibility request has been refused, a local attorney can clarify where things stand.

Sign before the first coat of paint, not afterward.

• Each tenant named on the lease signs and dates the pages.
• The owner or an authorized manager signs them too.
• The signed copy attaches to the original lease.
• Photos, receipts, and any permit stay filed with it.
