What San Mateo's heating rule means for your fireplace
San Mateo Municipal Code 7.14.060, part of the city's Property Maintenance Code, requires dwellings to have heating facilities and states that fireplaces may not be used as the means to provide required heating (source: City of San Mateo Municipal Code - Section 7.14.060 Mechanical and Electrical Requirements).

Who the rule applies to
The section is written for dwellings, so it covers the home you live in as well as a home you rent out. For landlords and property managers, the practical point is simple: a working fireplace doesn't stand in for the heating a unit is required to have.
What it changes about a fireplace repair
- The goal of a repair is a fireplace that drafts properly and burns safely. It is not to make the fireplace qualify as the home's heat source, because under the code no repair can do that.
- If the home's main heating isn't working, fixing the fireplace doesn't address the requirement. The heating facilities themselves are what need attention.
- Whether you repair a fireplace, convert it or leave it unused comes down to how you want to use it, not to meeting the heating requirement.
Don't push a damaged fireplace through a cold night
Stop using a fireplace with cracked firebox brick, a failing damper or smoke spilling into the room until it has been looked at. The code doesn't let a fireplace count as required heat anyway, so there is no reason to rely on one that's damaged.

Fireplace repair in brief
Fireplace repair covers the parts of a fireplace that wear out or fail. That means cracked brick and loose mortar in the firebox, damaged refractory panels in factory-built units, a deteriorated smoke chamber, and a damper that sticks or won't close. It also covers cracked glass, doors that no longer seal, and draft problems that push smoke into the room. Brick fireplace repair and smoky fireplace repair are two of the most common requests. Gas fireplace and gas appliance work is offered, and we work on all major brands. The full scope is laid out on our fireplace repair service page.
When to book a repair, and when something else fits better
- Repair fits when the fireplace is basically sound but a part has failed. Typical signs are spalled or cracked brick, eroded mortar joints, a broken refractory panel, a sticking damper, smoke rolling into the room, cracked glass or a door that won't latch.
- If the unit is beyond saving or you want a different kind of fireplace, fireplace installation in San Mateo is the better fit. That includes inserts and conversions.
- If you're thinking about switching fuels rather than fixing what you have, our guide to gas vs. wood-burning fireplaces walks through the trade-offs.
- If you don't know what's wrong, a fireplace inspection is a sensible first step before deciding on any repair.
