A phone call, a probate letter, or a quiet conversation with siblings can turn a family home into a rental property overnight, whether you planned for it or not.
One week you're grieving and sorting through decades of belongings. Next, you're holding keys, a mortgage statement, and a tenant's phone number, with no idea what any of it means for you legally or financially. Maybe you've never screened a tenant or read a lease clause in your life.
This guide walks through the first decisions every new Marin County landlord needs to make, so you're not figuring it out alone.
Key Takeaways
Your tax basis resets at inheritance, which can significantly reduce future capital gains exposure if you eventually sell.
Existing tenants and leases transfer with the property, so you inherit their terms, not a blank slate.
California and Marin County stack compliance requirements, from statewide deposit limits to a local rental registry.
Habitability and insurance obligations start the moment you hold title, whether or not you feel ready to manage them.
Deciding between self-management and professional management early prevents costly missteps in the first 90 days.
What You Actually Own before You Do Anything Else
Before setting a rent price or calling a handyman, it helps to understand exactly what changed hands. An inherited property carries financial and legal details that a purchased property does not.
The Basis Reset That Could Save You Real Money
When you inherit real estate, federal tax law generally resets the cost basis to the property's fair market value on the date the previous owner passed away, rather than to what they originally paid decades ago. That reset, known as the step-up in basis, can meaningfully reduce the capital gains you would owe if you later sell.
What it means: If a parent bought a San Rafael home in 1985 for $150,000 and it is worth $1.4 million today, your new basis for tax purposes is generally the $1.4 million value, not the original price.
Real-world example: A Marin heir who sold an inherited duplex within a year of receiving it owed little to no capital gains tax because the sale price was close to the stepped-up value. Confirm your specific basis and any estate tax filings with a CPA or estate attorney. The IRS's guidance on the basis of assets is a useful starting reference, though this is educational information, not tax advice.
Existing Tenants and Lease Terms You Inherited Too
If the property was already rented, the lease survives the change in ownership. You cannot raise rent, change terms, or ask a tenant to leave simply because the deed was transferred to you. California law treats you as stepping into the prior owner's shoes, including deposit obligations.
How Title Is Held Matters
Whether the property passed through a living trust, a probate proceeding, or joint tenancy with a sibling affects how quickly you can act, who has to sign documents, and whether a free rental analysis makes sense now or once title fully clears.
The Compliance Checklist Marin Adds to State Law
California landlord-tenant law applies statewide, but Marin County and its cities add their own layers. First-time landlords are often caught off guard by rules that longtime owners have long since built into their routine.
Security Deposit Rules Changed Recently
Under Assembly Bill 12, most California security deposits are now capped at one month's rent, effective July 1, 2024, with a narrow exception for small landlords. Assembly Bill 2801, effective for move-outs handled from April 1, 2025 onward, requires landlords to photograph the unit before and after any repair or cleaning deductions are made.
Starting January 1, 2026, Assembly Bill 414 also gives landlords the option to return deposits electronically. These rules live in California Civil Code Section 1950.5, and getting the paperwork wrong can expose you to double the deposit in damages.
Marin County's Rental Registry
Marin County requires rental owners to file and update registry information annually, tracking rent levels, vacancies, and exemptions. Missing a filing or an update is an easy mistake for someone who never expected to be a landlord in the first place.
Habitability Isn't Optional
You now carry the legal duty to keep the property livable: working plumbing, heat, weatherproofing, and safe electrical systems. An older inherited home can carry deferred maintenance that was never visible to a grieving family sorting through the estate.
What it means: A habitability complaint filed in the first few months of ownership can be far more stressful and far more expensive than a routine repair handled proactively.
Deciding How Involved You Want to Be
Every heir eventually faces the same question: manage it yourself, or hand it to a team who already knows Marin's rules, vendors, and rental market.
Time. Screening tenants, coordinating repairs, and tracking compliance deadlines take hours you may not have while also settling an estate.
Distance. Many heirs live entirely outside Marin County, making same-day maintenance calls or move-in inspections impractical.
Risk tolerance. A missed notice or an improperly handled deposit can turn a modest dispute into a costly one.
Rental strategy. A rent-versus-sell calculator or ROI calculator can clarify whether holding the property as a rental even makes financial sense compared to selling.
Full-service property management exists precisely for owners in this position: people who now own a rental asset but never intended to become landlords.
Protecting the Investment from Day One
Once you know what you own and what the law requires, protecting the property becomes the priority. Start with tenant screening standards if the unit is vacant or turning over, since a careless placement decision is one of the most common first-year mistakes.
Confirm rent collection systems are set up correctly so payments do not lapse during the transition. Review insurance coverage immediately, since many inherited policies are still in the previous owner's name and may not reflect rental use.
Set up clean accounting from day one, both for your own recordkeeping and to support the stepped-up basis if you sell later. And understand your eviction process options in advance, even if you never expect to need them.
FAQs
Do I have to keep the tenant who was already living there?
Yes, in most cases. The lease transfers with the property, and you cannot terminate a tenancy simply because ownership changed hands. You would need a legally valid reason under California and Marin rules to end an existing tenancy.
How soon do I need to register the rental with the county?
Marin County's rental registry requirements apply as soon as you begin renting the unit, so it is worth confirming your filing status early rather than assuming a prior owner's paperwork still applies to you.
Is it better to sell right away or hold the property as a rental?
It depends on your basis, the local rental market, your distance from Marin, and how much time you can realistically commit. Running the numbers through a rent-versus-sell comparison before deciding is far safer than guessing.
An Inherited Property, a Real Decision: What Happens from Here Is Up to You
Inheriting a rental property in Marin County comes with real opportunity and real responsibility at the same time: a stepped-up tax basis, an existing tenant relationship, and a compliance checklist that spans state law and county rules. There's also the emotional weight of it all, since the property likely still feels like family, not just an asset on a balance sheet.
None of it has to be sorted out by trial and error, and getting even one piece wrong (a missed registry filing, a mishandled deposit) can turn an inheritance into an expensive lesson.
