The request almost always arrives casually. A tenant texts to say their partner is moving in next month, or that a sibling needs a place to land for a while, or that they have found someone to take the spare bedroom and split the rent. Sometimes the message is a courtesy. Sometimes it is a notification of something that already happened three weeks ago.
How an owner answers that text matters more than most people expect. Handled well, adding an occupant is a retention win: the household gets more stable, the rent gets easier to cover, and a good tenant stays another two years. Handled badly, you end up with an unscreened adult living in your property with no lease obligation, no liability for damage, and — if you ever need to remove them — a genuinely awkward legal position.
Here is the process we use across Richmond, Henrico, Chesterfield and Hanover, and the reasoning behind each step.
Quick Answer
A Richmond landlord should treat any new adult occupant as a new applicant: require a written request, screen the person against the same published criteria used for everyone, and then formalize the change with a lease addendum or a new lease rather than a verbal yes. Approving someone without adding them to the lease is the single most common mistake, because it creates a resident who lives in the property but owes you nothing under it. Screening criteria must be applied identically to every applicant to stay on the right side of fair housing law.
Occupant, Tenant, and Guest Are Three Different Things
Most lease disputes about roommates come from vocabulary, not bad faith. The three terms are not interchangeable.
A tenant has signed the lease. They owe rent, they are liable for damage, they have the right to occupy, and they are subject to every obligation in the document. If there are three tenants, they are typically jointly and severally liable, meaning you can pursue any one of them for the whole balance.
An occupant lives in the property with permission but has not signed the lease. Depending on how your lease is written, they may be authorized by name. They generally have no rent obligation to you and no direct liability for damage.
A guest is temporary. Nearly every well-drafted Virginia lease caps guest stays — commonly somewhere in the range of seven to fourteen consecutive days, or a total number of days per year — precisely so that “my cousin is visiting” does not quietly become a fourth resident.
When a tenant asks to “add someone,” your first job is to find out which of these three they actually mean. A partner moving in permanently is a tenant question. A parent staying six weeks after surgery is a guest question. They deserve different answers.
Why an Unscreened, Unsigned Adult Is a Real Risk
Owners who self-manage often approve roommates informally because it feels neighborly and low-stakes. The problems show up later.
- No liability for damage. If the unlisted occupant puts a hole in a wall or leaves a bathtub running, your claim runs against the signed tenant only — and against a security deposit that was sized for the original household.
- No rent obligation. If the original tenant leaves and the roommate stays, you have someone in possession who never agreed to pay you anything.
- No screening. You have no idea whether this person has a recent eviction judgment, an income problem, or a history that your written criteria would have flagged.
- Removal is harder. Getting an unauthorized occupant out is not a simple matter of asking. Anyone in lawful possession of a residence in Virginia generally has to be removed through the court process, not by changing locks.
- Occupancy limits. Adding people can push a property past reasonable occupancy standards or past what the septic system, in the outer counties, was designed to handle.
None of this means the answer should be no. It means the answer should be a process.
The Five-Step Process
1. Require the request in writing
A text message is fine as a starting point, but move it to a written request that names the person, states the intended move-in date, and confirms whether the current tenants are asking to add someone or to swap someone out. Those are different transactions. Adding a partner to a household of two is straightforward. Replacing a departing roommate is a lease assignment and needs more care, including a decision about the existing security deposit.
2. Have the new adult apply
Every adult who will occupy the property should complete the same application everyone else completed. Same form, same fee if you charge one, same documentation. This is not about suspicion; it is about consistency. The moment you screen one applicant more loosely than another, you have created a fair housing problem that is very difficult to explain later.
In Virginia, application fees and deposits are regulated, and there are limits on what may be charged and what must be refunded if an applicant is not approved. If you are not certain your fee structure is compliant, that is worth checking before you collect anything.
3. Screen against published, written criteria
Your criteria should already exist in writing before the request arrives — income thresholds, credit standards, rental history, and how you handle criminal history. Apply them to the new applicant exactly as written.
One nuance specific to roommate additions: decide in advance whether your income requirement applies to the household in aggregate or to each adult individually. Both are defensible. What is not defensible is applying household income when you like the applicant and individual income when you do not. Write the rule down, then follow it.
Federal fair housing law, administered by HUD, and the Virginia Fair Housing Law both prohibit discrimination on protected bases. Note that an assistance animal accompanying a new occupant is a reasonable accommodation question, not a pet question, and is evaluated separately from your screening decision.
4. Paper the change properly
If you approve, you have two clean options:
- A lease addendum adding the new person as a tenant for the remainder of the current term, signed by everyone including the existing tenants.
- A new lease for a fresh term with all parties listed. This is often the better choice, because it resets the term, updates the rent to current market if appropriate, and avoids stacking addenda on an aging document.
Either way, the document should address rent responsibility, the security deposit, occupancy, and whether the addition changes anything about parking, pets, or utilities.
5. Update the deposit and the record
More people generally means more wear. Whether you can increase the security deposit mid-tenancy depends on your lease and on Virginia’s cap on total deposit amounts, so check both before asking. At minimum, update your records, re-run a move-in style condition report if the household composition is changing substantially, and make sure the new tenant receives the same required disclosures and copies of the lease that everyone else got.
Addendum vs. New Lease: Which to Use
| Consideration | Lease Addendum | New Lease |
|---|---|---|
| Speed | Faster; one page | Slower; full document |
| Lease term | Unchanged | Resets, improving retention |
| Rent adjustment | Generally not appropriate mid-term | Can reset to market |
| Deposit changes | Limited by existing lease | Easier to address cleanly |
| Best for | Partner joining an existing household | Roommate swaps, major changes, leases near renewal |
Our general rule: if the lease has more than six months left and the change is simple, use an addendum. If renewal is approaching anyway, or if someone is leaving as someone else arrives, write a new lease.
Roommate Swaps Deserve Extra Attention
When one roommate leaves and another arrives, three things need resolving that a simple addition does not raise.
The deposit. The deposit you hold belongs to the tenancy, not to an individual. The cleanest approach is to keep holding it, have the departing and arriving roommates settle up between themselves, and document in writing that the deposit remains with the property. Refunding a departing roommate directly mid-tenancy creates accounting problems and can trigger disputes at move-out.
Condition documentation. Do a written and photographed walkthrough at the swap. Without it, you cannot later distinguish damage caused before the change from damage caused after, and neither can the tenants.
Release of the departing tenant. If you do not formally release them, they may remain liable. If you do release them, say so explicitly. Ambiguity here is what produces angry phone calls fourteen months later. Our guide to lease and tenancy topics in the Learning Center covers related mid-lease changes in more depth.
When It Is Reasonable to Say No
You can decline, but the reason must be consistent and documented:
- The applicant does not meet your published screening criteria.
- The addition would exceed reasonable occupancy standards for the property’s bedroom count.
- The property is on a septic system rated for a specific household size — a real constraint in parts of Goochland, Powhatan, New Kent and rural Hanover.
- An HOA or condominium association restricts occupancy or requires its own approval.
- The person has already moved in without permission and the tenants misrepresented the situation.
What is never a valid reason is anything touching a protected class. If you find yourself constructing an explanation after the fact, stop and get advice before you send it.
The Unauthorized Occupant Who Is Already There
This is the harder version of the problem, and it comes up regularly at routine inspections — an extra car in the driveway, a second set of everything in the bathroom, mail in an unfamiliar name.
The productive move is usually not a confrontation. It is a written notice identifying the lease provision at issue and offering a path to compliance: have the person apply and be added, or have them vacate by a stated date. Most tenants take the first option, and you end up with a properly documented tenancy instead of a vacancy.
If the tenant refuses both, you are into lease enforcement, and Virginia’s notice requirements are specific. That is the point to involve a property manager or an attorney rather than improvising.
Frequently Asked Questions
Can a tenant add a roommate without my permission?
Not if your lease requires written landlord consent for additional occupants, which most well-drafted Virginia leases do. If your lease is silent on the point, your position is much weaker — which is a good reason to review the document before your next renewal cycle.
Do I have to let a tenant’s partner move in?
No. There is no automatic right for an unlisted adult to occupy a rental. You may require them to apply and meet your standard criteria. You simply cannot apply different standards to different applicants.
Can I raise the rent when someone is added mid-lease?
Generally not during a fixed term, unless the lease specifically provides for it. If the added occupancy justifies a different rent, the appropriate moment is renewal, with a new lease.
Can I charge an additional deposit for a new roommate?
Possibly, subject to Virginia’s cap on total security deposits and to what your lease permits. Confirm both limits before requesting anything.
What if the original tenant moves out and only the roommate stays?
If the roommate was properly added to the lease, the tenancy continues with them. If they were never added, you have an occupant with no lease obligation and should address it promptly and in writing.
Does a minor child count as an added occupant?
Children are treated very differently from adult roommates, and familial status is a protected class under fair housing law. Do not screen or refuse based on the addition of a child. If you have questions about occupancy limits in that context, get advice first.
How long can a guest stay before they become an occupant?
Whatever your lease says — which is exactly why the lease should say something. Without a written guest provision, the line is a matter of argument rather than a matter of record.
Where Mission Realty Fits
Roommate additions are routine for us and stressful for most self-managing owners, largely because the paperwork has to be right the first time. We screen every adult against the same written criteria, prepare the addendum or replacement lease, handle the deposit accounting, and document condition at the change — so that two years later, when someone moves out, the record actually supports whatever needs to happen next.
