HOUSING 101

Learn more about housing and what is possible in San Mateo County

The Bay Area is a great place to live.

But throughout the region and San Mateo County, there just isn’t enough housing for all income levels.

Since 2010, we have added over 100,000 jobs and only 10,000 homes.

While some communities have more jobs, and some have less, overall, we haven’t built enough housing in the past 30 years to keep a balance with the number of jobs we keep adding

Our population is also growing naturally – more people are living longer and our children grow up and move out into homes of their own

All this means that more housing is needed to keep things in balance, and not having enough housing across all incomes has meant rents and prices are higher.

 

Why do we need more affordable housing?

While a lot has been accomplished since the last round of Housing Element updates, the jurisdictions in San Mateo County are on track to see only 36% of the moderate to very low-income housing needed by 2022 get built.

 
 
 
 
 

The Bay Area is known throughout the country as being an expensive place to live.

The median income in San Mateo County – meaning the middle spot between the lowest and highest wages – is $104,700 for a single person. Some are making a lot more than others and wages for many haven’t kept up with how costly it is for housing in our economy.

We all rely on our essential service workers

For every six low-wage jobs in San Mateo County – and a low wage job is considered making about $20 an hour – we only have one home that such a worker could technically afford (an affordable home is considered around $1500 a month for rent, which is still about 50% of the full-time wage of a low wage worker).

THE IMPACT OF INEQUALITY OF WAGES

People are spending too much of their income on housing

This has resulted in overcrowding, or people living with more roommates or family members than the home can hold. It can also mean people stay in unsafe or unhealthy living conditions because they have no other option.

People are moving farther away

This has resulted in longer commutes to work for those who are moving and more traffic in our communities due to the increased commuting.

People are leaving altogether

Sometimes, people can no longer make the direct and indirect costs of traveling far for work pencil out, and they leave our communities for good, which can have a lot of ripple effects, like your kid’s favorite teacher or your dental hygenist leaving the community.

 

It is easier to meet the need for market-rate housing because developers will build it and those who can afford it will pay for it. However, it is a bit more complicated when trying to make enough low to moderate-income housing. These types of homes require more subsidies or assistance from governments, and there just isn’t enough to go around.

THE SOLUTION

There is a lot of housing between large, single-family homes and apartment complexes that have been here all along.


Many types of housing are possible in your community and likely already exist in your neighborhood. You might live next to one, in one, or pass by one every day.

Duplex: two attached homes with individual entries

Triplex or Fourplex: 3-4 attached homes with shared or individual entries

Cottage Cluster: a group of small detached homes with a shared courtyard

Live-work: home above a storefront in a commercial zone

Low rise: 2-3 stories with a shared entry

Mid-rise: 3-4 stories with a shared entry

High-rise: 5+ stories with a shared entry (usually in downtowns or higher density zones)

Historically, these types of homes were frequently built, but somewhere along the way, became less common in favor of single-family homes. 

Learn more about small housing

Accessory Dwelling Units (ADUs) are an increasingly popular way to create more housing in existing neighborhoods.

ADUs are flexible spaces added to existing homes that can house family, provide additional revenue as a rental property, or be used later in life for home health care or for downsizing from the main home. State laws have made them allowed in every city and town and easier to build. To learn more about ADUs, as well as small homes, visit the Casita Coalition.

Some people refer to duplexes, triplexes/fourplexes, townhomes, cottage clusters and live-work homes as “Missing Middle Housing.”

This is a term created by Dan Parolek at Opticos Design here in the Bay Area. To learn more visit here. These homes can offer young families, workers, students, and our aging population more options when just starting out or transitioning to something smaller.

All types of small homes aren’t necessarily affordable - that will depend on the market, the landlord, or if they include below market-rate units or ownership opportunities. However, allowing for more housing to be added to communities can increase the supply, which can help us balance things out.

Creating more housing—and more diverse housing choices—means:

  • Young families can find an affordable starter home

  • Young adults moving out of their childhood home and into the housing market can stay in the cities they grew up in

  • Our aging population will have more options for retirement, including downsizing, providing housing for on-site health or home care, and staying in their communities

  • Workers - teachers, firefighters, health care workers, essential workers - can find homes near job centers (which will reduce traffic!)

  • Your children and grandchildren can stay near you in the communities they feel a part of

  • More people will have more opportunities, across incomes, to rent or own homes in the places they live, work and love
