Before You Start: Key Decisions
Long-Term vs. Short-Term Rental
Your rental strategy affects everything from permits to insurance:
Long-Term (12+ months)
- + Stable, predictable income
- + Lower turnover costs
- + Simpler regulations
- - Less flexibility
Short-Term (Airbnb, VRBO)
- + Higher income potential
- + Flexibility to use yourself
- - More management work
- - Often restricted for ADUs
Note: Many jurisdictions prohibit or heavily restrict short-term rentals of ADUs. Check your local ordinances before deciding.
Self-Manage vs. Property Manager
Property managers typically charge 8-12% of monthly rent but handle tenant communications, maintenance coordination, and rent collection. For a single ADU on your property, self-management is usually practical, but a manager makes sense if you travel frequently or prefer hands-off ownership.
Step-by-Step Rental Setup
Check for Required Rental Permits
Many cities require rental property registration:
- • Rental license/permit: Annual fee, typically $25-200
- • Business license: Some cities require this for rental income
- • Rental inspection: Some jurisdictions inspect before renting
- • Short-term rental permit: If doing Airbnb/VRBO
Contact your city's housing or business licensing department.
Get Landlord Insurance
Your homeowner's policy likely doesn't cover rental activities:
- • Landlord policy (DP-3): Covers the structure, liability, and lost rent
- • Umbrella policy: Extra liability protection ($1M+ recommended)
- • Require tenant renter's insurance: Protects their belongings, reduces your liability
Pro tip: Landlord insurance typically costs 15-25% more than homeowner's insurance for the same coverage. Shop multiple quotes.
Draft Your Lease Agreement
A solid lease protects both you and your tenant. Include:
- • Rent amount, due date, and late fee policy
- • Security deposit amount and terms
- • Lease term (month-to-month or fixed)
- • Utility responsibilities
- • Pet policy
- • Maintenance responsibilities
- • Guest and parking policies
- • Rules specific to ADU living (shared spaces, noise, etc.)
Important: Use a state-specific lease template or have an attorney review yours. Landlord-tenant laws vary significantly by state.
Set Up Tenant Screening
Good tenant screening is crucial for ADUs where you live nearby:
- • Credit check: Look for 600+ score, no recent evictions
- • Background check: Criminal history (follow fair housing laws)
- • Income verification: 2.5-3x rent in monthly income
- • Rental history: Contact previous landlords
- • Employment verification: Confirm job and income
Services like TransUnion SmartMove, Avail, or RentPrep cost $25-55 per applicant.
Set Up Rent Collection
Make paying rent easy and trackable:
- • Online platforms: Avail, Buildium, Rentec Direct (often free for 1 unit)
- • Payment apps: Venmo, Zelle, PayPal (simple but less documentation)
- • Bank ACH: Set up automatic transfers
- • Checks: Old-fashioned but some tenants prefer it
Pro tip: Use a platform that automatically sends payment reminders and tracks payment history for tax purposes.
Open a Separate Bank Account
Keep rental finances separate for easier accounting:
- • Dedicated checking account for rental income and expenses
- • Makes tax preparation much simpler
- • Required in some states for security deposits
- • Protects personal assets in case of lawsuits
Fair Housing Compliance
Required: Know Fair Housing Laws
As a landlord, you cannot discriminate based on race, color, national origin, religion, sex, familial status, or disability. Many states and cities add additional protected classes (sexual orientation, source of income, etc.).
How to Set the Right Rent
Research comparable rentals in your area:
- Zillow/Apartments.com:Search active listings similar to your ADU
- Rentometer:Free tool that analyzes rent by address
- Craigslist:See what similar units are asking
- Factor in:New construction, private entrance, included utilities, parking
ADU premium: New ADUs often command 10-20% above comparable older apartments due to modern features, energy efficiency, and better construction.
Frequently Asked Questions
Do I need an LLC to rent out my ADU?
Not required, but some landlords form an LLC for liability protection. For a single ADU on your property, adequate insurance (landlord policy + umbrella) often provides sufficient protection without the cost and complexity of an LLC.
How much security deposit can I charge?
State law governs maximum deposits. Common limits: 1-2 months' rent for unfurnished, 2-3 months' for furnished. California caps it at 1 month total as of 2024. Check your state's specific rules.
Should I include utilities in rent?
For ADUs, including utilities simplifies things (no sub-metering needed) and can justify higher rent. If you include utilities, specify a reasonable use limit in the lease to prevent abuse. Alternatively, install sub-meters for tenant responsibility.
What if I want to use the ADU later for family?
Use a month-to-month lease or include a clause allowing termination with proper notice (typically 30-60 days). Be aware that some rent control jurisdictions restrict owner move-in evictions. Plan ahead and understand your local laws.
