Renting Your ADU for Short-Term Rentals

in San Mateo, CA
Step-by-Step Guide: Renting Your Accessory Dwelling Unit (ADU) for Short-Term Rentals in San Mateo, CA

If you're ready to make money with your ADU in San Mateo, CA renting it out as a short-term rental on platforms like Airbnb or VRBO, here's a friendly guide to help you get started, even if you're new to this!

1. Understand the Local Regulations

Before listing your ADU, it's essential to understand the rules:

  • Check Zoning and Permits: San Mateo has specific regulations for short-term rentals. Make sure your ADU is in a zone that allows short-term rentals.
  • Obtain a Short-Term Rental Permit: In San Mateo, you need a permit to operate a short-term rental. This includes your ADU if you plan to rent it out for less than 30 days at a time.
  • Know the Occupancy Limits: Understand the maximum number of guests allowed in your ADU according to local laws.
2. Prepare Your ADU

Your ADU should be ready to impress potential guests:

  • Furnish and Decorate: Make sure your ADU is fully furnished and comfortable. Add some personal touches like local art or a cozy throw blanket.
  • Stock Up on Essentials: Provide basic amenities such as towels, toiletries, kitchenware, and cleaning supplies.
  • Ensure Safety: Install smoke detectors, carbon monoxide detectors, and provide a fire extinguisher. Ensure all locks and windows work properly.
  • Wi-Fi and Entertainment: High-speed internet is essential. Consider adding a smart TV or other entertainment options to make your guests’ stay enjoyable.
3. Take Great Photos

First impressions matter:

  • Use Good Lighting: Take photos during the day when natural light is abundant.
  • Highlight Key Features: Showcase unique features like a beautiful patio, modern kitchen, or a cozy bedroom.
  • Consider Hiring a Professional Photographer: If budget allows, a pro can make your ADU look even more appealing.
4. List Your ADU on Short-Term Rental Platforms

Now that your ADU is ready, it’s time to list it:

  • Choose a Platform: Popular options include Airbnb and VRBO. You can list on both to maximize your exposure.
  • Create a Catchy Title: Think of a title that highlights the best feature of your ADU, like “Cozy Garden Retreat in the Heart of San Mateo.”
  • Write a Detailed Description: Describe your space accurately. Include details about the neighborhood, nearby attractions, and what makes your ADU special.
  • Set Your Pricing: Research similar listings in your area to set a competitive price. Don’t forget to factor in cleaning fees and any additional guest fees.
5. Set House Rules

Clear rules make for smoother stays:

  • Establish Check-In and Check-Out Times: Standard times are 3:00 PM for check-in and 11:00 AM for check-out, but you can adjust to what works best for you.
  • Outline Noise Restrictions: If you have neighbors close by, consider setting quiet hours.
  • Pet Policy: Decide whether you’ll allow pets and under what conditions.
  • Smoking Policy: Be clear if smoking is not allowed inside your ADU.
6. Manage Bookings and Communication

Good communication is key to great reviews:

  • Respond Quickly: Promptly reply to booking inquiries and messages from guests.
  • Use Automated Tools: Platforms like Airbnb offer tools to send automated check-in instructions and reminders.
  • Be a Helpful Host: Provide recommendations for local restaurants, attractions, and transportation options.
7. Clean and Maintain Your ADU

A clean space leads to happy guests:

  • Hire a Cleaning Service: If managing cleaning yourself is too much, consider hiring a professional service to clean between guests.
  • Regular Maintenance: Keep up with regular maintenance tasks like checking the plumbing, replacing light bulbs, and tending to the garden if you have one.
8. Collect Reviews and Improve

Positive reviews will attract more guests:

  • Ask for Reviews: After each stay, politely ask your guests to leave a review.
  • Learn from Feedback: If a guest points out an issue, address it promptly to avoid future complaints.
  • Update Your Listing: Keep your listing fresh by updating photos, changing the description, or adjusting prices based on seasonal demand.
9. Handle Finances and Taxes

Keep track of your earnings and obligations:

  • Track Your Income: Use a spreadsheet or financial software to track your rental income.
  • Set Aside Money for Taxes: Short-term rental income is taxable, so be sure to set aside money to cover your tax obligations.
  • Consider Professional Help: If you’re unsure about tax filings, consult with an accountant familiar with short-term rental income.
10. Enjoy the Experience!

Frequently asked questions

Accessory Dwelling Units (ADU’s)

Do I need to have a primary residence before adding an ADU?
In most cases yes. An ADU is meant to be an add on to your existing home or multi-family dwelling. Some jurisdictions will allow you to build an ADU prior to building the primary residence, if building plans for the primary residence have been approved.
Do all ADU’s require a building permit?
In California the answer is yes. Many states now offer accelerated review processes, and even financial assistance to minimize the administrative hurdle to getting your project approved. Ikkonic’s team will handle all these entitlements as part of the standard purchase of your ADU.
Who pays for the building permits?
Building Permit fees are the clients responsibility. Each locale around the country will have unique building fees based on a variety of factors. Our permit team will present these fees to you as part of the contract process. Rest assured, there will be no surprises, as we capture and relay these costs as soon as there is enough information available about your project.
What do I need to do to prepare for delivery of my ADU?
Sit back and relax, and enjoy the show! Our expert logisticians handle all the red tape and jump through every necessary hoop to make sure your delivery is handled with care and precision. No two deliveries are alike, and our team is battle tested to ensure a seamless process.
Can I finance my ADU the same way I finance a home purchase?

Financing your ADU is much more like financing an addition to your home. Keep in mind, this is an add on structure that can not be leveraged individually. From the lender's perspective, you have or will be adding value to your real estate, and the loan ratios now need to be recalculated to make sure the lender is comfortable with the amount of debt versus the new value after the ADU is complete and installed.

We have great relationships with lenders that will assist in the loan process. They offer products like:

  • Home Equity Lines of Credit
  • Remodel/Addition Loans
  • Personal Loans (Unsecured)
  • Revolving Credit Loans (Credit Cards)
  • Equity Partnership Loans
  • State and Federal Grants

 Single Family Residences (SFR’s)

How do I know if the land I own or may be purchasing is ok to build a home on?
All Single Family home purchases require a feasibility study prior to completing the purchase. We charge a small fee for this service to make sure things like zoning, setback restrictions, easements or floodplain issues won't impact your ability to obtain a building permit. If you move forward with us after the study is completed, the fee is credited back to your overall purchase price.
How long does it take to get a building permit?
The time it takes to obtain a building permit will vary by location. Many of the time delays in a typical home building process have been mitigated by your selection of a pre-designed model that has been partially reviewed and approved in advance. Your site conditions however must be reviewed to ensure your foundation systems meet local building code. 3-6 months is typical in many jurisdictions. Our team is expertly qualified to push this process as quickly as possible, and with all our resources in house we are well positioned to move through the process efficiently.
Is there anything that can be done to make the permit process go faster?
Many jurisdictions do have a fast track process available. This typically comes with an additional fee that is paid to a “Permit Expeditor”. These are consultants that have strong relationships with local planning and Building departments, and are highly effective in most cases to speed up the process, sometimes by as much as 50%. Results will vary based on the specific circumstances of your project.
How long will it take to install my ikkonic home?
Your home will be delivered and installed in as little as a week, and no more than 2 weeks. This of course does not consider rare acts like extreme weather conditions or natural disasters. If you keep in mind that the home has been completely built and inspected in our factories, and the only work to be done on site is unwrapping, setting and connecting your modules to each other, you can understand how quickly this occurs. Your project manager will carefully walk you through the installation process, as it is truly an exciting day to see your new home arrive!
Is financing an ikkonic modular home the same as financing a typical home construction?
The process is the same. Our lenders will review all the typical components of the project; land cost, construction cost, and final value of the completed home. Where the nuance comes in is the draw schedule for construction. Because we purchase all the materials for the home in advance of beginning production of the project, upfront deposits are much higher than site construction. We work with lenders that understand this process and help you understand the cash requirements well in advance of approving the loan.
