San Mateo County HOA Guide

Millbrae HOA Guide: Local Rules for Boards and Owners

Millbrae has about 23,000 residents, and about six in ten homes are owner-occupied. New artificial turf is banned citywide, and smoking is banned inside condo and townhome units and in their common areas.

This guide collects the city rules a Millbrae board runs into most often, and points you to the How2HOA guide that explains what to do about each one.

Local rules on this page were checked against the City of Millbrae’s website and the Millbrae Municipal Code on October 27, 2026. Online codes can lag behind the most recent ordinances, and some city documents would not open for us, so confirm the current rule with the office listed before you act on it. Sources are listed at the bottom of the page.

HOAs in Millbrae at a glance

We did not find an official count of Millbrae’s HOAs or a typical dues figure, so we do not quote one. The public record does show how the city is set up:

City waterthe city sells water from the San Francisco regional system.
A fire assessmenta Fire Suppression Assessment is levied on Millbrae properties, renewed through 2033-34 with yearly increases capped at 3%.
Contract servicespolice service comes from the San Mateo County Sheriff, and fire service from the Central County Fire Department.
Fire hazard zonesa 2025 local fire hazard map went to the City Council, and Central County Fire says very high hazard zones carry defensible-space and home-hardening rules.

A landscape or maintenance district is easy to confuse with an HOA. A district assessment is on the property tax bill and pays the city. Association dues pay for what your association owns.

Local rules

Rules that apply in Millbrae

Three layers of rules apply to a Millbrae association. State law comes first, mainly the Davis-Stirling Act. City ordinances apply to every property, whether or not it is in an HOA. Your governing documents can then be stricter than the city in most areas, and state law limits them in a few. The city does not enforce your CC&Rs, and your CC&Rs do not excuse anyone from a city rule.

No new artificial turfBanned citywide since January 1, 2024.

Installing or using synthetic grass or artificial turf is prohibited in Millbrae (section 8.65.040). Turf legally installed before January 1, 2024 may stay if it is maintained, taut and permeable, and no one parks on it. Once it is damaged to 35% of its replacement cost, or can no longer be kept up, it must be replaced with water-efficient natural landscaping.

Civil Code section 4735 limits association rules, not the city’s ban, so in Millbrae a lawn conversion cannot use artificial turf. If your board has questions about how the city ban applies to your community, ask your attorney. The city’s Lawn Be Gone rebate pays $2 per square foot of sprinkler-irrigated lawn replaced, with a 200-square-foot minimum. Water Division: (650) 259-2339.

A state law passed in 2023 (AB 1572) bars the use of drinking water on nonfunctional turf in HOA common areas starting January 1, 2029. The law stops the watering; it does not require removing the lawn. A board that decides to replace decorative lawn can use a rebate, where one is offered, to pay for part of the conversion.

What to do about it: put the turf conversion in your numbers with Planning Your HOA Budget and Understanding HOA Reserve Studies, then compare landscape bids with the Vendor Comparison Worksheet.

The condo smoking banNo smoking in units, on balconies or in common areas.

Smoking is prohibited inside any unit of a multi-unit residence, including condominiums and townhomes and their patios and balconies, in enclosed or unenclosed common areas and within 40 feet (chapter 5.95). Single-family homes with a detached ADU and owner-occupied duplexes and triplexes are excluded. Code Enforcement: (650) 259-2440.

This is city law, so a board does not have to rely only on its CC&Rs. Post signs in common areas and point owners to the city when complaints come in.

Short-term rentalsPrimary residence only, and 100 unhosted nights a year.

Short-term rentals need a city permit, and the home must be the host’s primary residence, lived in at least 265 nights a year (chapter 7.30). Hosted stays have no night limit. Unhosted stays are capped at 100 nights a year and need director approval, a $1,000 refundable deposit and two agents who respond within 30 minutes. The city says ADUs may not be used, and the occupancy tax is 14%. California Civil Code section 4741 limits how far an association can restrict rentals generally, but it does not stop an association from prohibiting rentals of 30 days or less.

Protected treesAny tree 10 inches across needs a permit.

A significant tree is any species with a trunk 10 inches or more in diameter at 54 inches above grade, apart from a few exempt species such as acacia, fruit trees, palms and blue gum (chapter 8.60). Pruning more than a quarter of a protected tree, or removing, relocating or planting one, takes a permit. No removal may happen during the 10-day appeal period, and permits last 45 days. Replacement ratios rise with size, up to four 24-inch-box trees for a tree over 24 inches. Tree permits: (650) 259-2341.

What to do about it: How to Hire a Contractor for Your Homeowners Association covers what to require of a tree service before work starts.

Trucks, trailers and yard parkingNo trailers on the street, whatever their weight.

No vehicle may stay on a street or alley more than 72 hours. Trucks other than pickups and all trailers, including house trailers, may not park on public streets, regardless of weight, except while loading or serving a property on the block. Storing trailers, campers, RVs, commercial vehicles or boats in front yards, other than on driveways, or in unpaved areas visible from the street is a nuisance (section 6.25.050).

Your association’s rules can be stricter.

Private streets and city enforcementWe found no private roads designated for Vehicle Code enforcement.

We did not find a designation of private roads for Vehicle Code enforcement in the parts of Millbrae’s code we could read. Where no designation exists, enforcing parking and speed rules on association-owned streets usually falls to the association, so ask the police whether any roads in your community are designated.

Bins and work hoursBins out no more than 12 hours before and after pickup.

Garbage and recycling carts may go out no more than 12 hours before collection and must come in within 12 hours after. Construction or repair work is allowed from 7:30 a.m. to 7 p.m. on weekdays, 8 a.m. to 6 p.m. on Saturdays and 9 a.m. to 6 p.m. on Sundays and holidays, unless the city authorizes other hours (section 6.25.050). A nuisance not corrected within 30 days of notice can bring a $500 civil penalty for each violation.

Is this a lot for a volunteer board to track?

City rules, district assessments, state law and your own documents all change, and someone has to keep up.

Quick answers

Questions Millbrae board members ask

Can our HOA install artificial turf?

No. New synthetic grass and artificial turf are banned citywide.

Can residents smoke on condo balconies?

No. The city bans smoking inside units, on patios and balconies, in common areas and within 40 feet.

When must bins come in?

Within 12 hours after collection. They can go out up to 12 hours before.

Can an owner park a trailer on the street?

No. Trailers of any weight may not park on public streets except while loading.

Can our HOA ban short-term rentals?

Yes, if your governing documents say so. Civil Code section 4741 does not stop an association from prohibiting rentals of 30 days or less, though under Civil Code section 4740 an owner who bought before a rental ban took effect is generally not bound by it. Ask your attorney. More in How to Handle Short-Term Rentals in Your Community.

Can our HOA refuse to allow ADUs?

Not outright on single-family lots. Civil Code section 4751 voids provisions that prohibit or unreasonably restrict ADUs. Millbrae allows ADUs of up to 850 square feet with one bedroom or 1,000 square feet with more, with attached ADUs also capped at half the main home, and junior ADUs of up to 500 square feet. Section 4751 still allows reasonable restrictions that do not unreasonably raise the cost of building one or effectively prohibit it, which the association can apply through architectural review.

Calendar

A Millbrae board’s year

The dates below follow the agencies’ own programs. The maintenance items are general good practice, not legal requirements.

WinterClear drains and gutters before storms.
SpringClear vegetation on any common area in a fire hazard zone before fire season.
June 30Residential parking permit stickers expire.
November and FebruaryProperty tax installments, which carry any landscape district, Mello-Roos and other special charges, are due November 1 and February 1 and become delinquent after 5 p.m. on December 10 and April 10, or the next business day when that date falls on a weekend or holiday. San Mateo County counts only a U.S. Postal Service postmark, not a private meter date, so pay online or mail early.

Keep the year on track: use the Board Meeting Checklist and the Annual HOA Budget Checklist.
