Victorian and Edwardian Homes in San Francisco: Historic Rules

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

When you buy a Victorian or Edwardian house in San Francisco, the rules that shape what you can change come from its historic status with SF Planning: whether it is an Article 10 landmark or sits in an Article 10 historic district, and which CEQA category (A, B or C) Planning assigns it. Those answers decide whether a new window, a rear addition or a facade change goes over the counter, needs a Certificate of Appropriateness, or needs a historic evaluation first. Seismic work on the old wood frame and any Mills Act contract are the other two items to settle before you remove contingencies.

This page covers the regulatory side of owning a pre-1920 house or flat. To tell an Italianate from a Queen Anne or a Classical Revival building, and for an inspection checklist, see our San Francisco Victorian homes buyer’s guide. Both sit within our San Francisco real estate guide.

Three layers of historic status

A house can carry one, two or all three of these designations, and each has different consequences.

Layer	What it is	What it triggers
Article 10 of the Planning Code	City landmarks and historic districts, designated by ordinance after Historic Preservation Commission review	Certificate of Appropriateness for exterior work; possible demolition delay
Article 11 of the Planning Code	Building ratings and conservation districts in the downtown C-3 districts	Permit to Alter for buildings and districts it covers
CEQA category (A, B or C)	Planning’s working status for environmental review, shown on the Property Information Map	Historic review when you apply for a building permit

SF Planning notes that California Register and National Register listings matter too, and that all three types of designation, local, state and federal, qualify a building to use the California Historical Building Code. But a Certificate of Appropriateness is required only for Article 10 resources, not for buildings listed only on the state or national registers.

Article 10 historic districts and landmarks

Planning’s GIS layer of Article 10 historic districts listed 16 districts when we checked in October 2026. The ones most likely to matter to a buyer of 19th- and early 20th-century homes:

District	Planning neighborhood	Period of significance
Alamo Square	Western Addition	1890 to 1915
Liberty Hill	Mission	1860s to 1906
Telegraph Hill	North Beach	Not stated in the layer
Webster Street	Pacific Heights	From 1878
Bush Street-Cottage Row	Western Addition	1874 to 1882
Blackstone Court	Marina	1849 to 1906
Duboce Park	Western Addition	1896 to 1913
Dogpatch	Potrero Hill	1867 to 1945
Chula-Abbey Early Residential	Mission	1865 to 1912
Alert Alley Early Residential	Mission	1890 to 1910

The other six are mostly commercial or civic: Jackson Square, Northeast Waterfront, South End, Civic Center, Market Street Masonry, and Clyde and Crooks. The two Mission early-residential districts are new; the layer dates both to February 12, 2026, under Ordinances 14-26 and 15-26. Lists published before 2026, including older Planning bulletins, leave them out.

Inside a district, each property is either a contributor or a non-contributor. For Alamo Square, adopted in 1984, Planning’s district layer counts 248 contributors among 273 properties; Planning’s Alamo Square walking tour, cited in our buyer’s guide, describes the district as 281 parcels. The two city sources count differently, so check any single address on the Property Information Map. Our Alamo Square guide, Telegraph Hill guide and Dogpatch guide cover those neighborhoods.

Individual landmarks are a separate list. Planning’s landmarks layer returned 394 records when we queried it, and Planning’s preservation page describes “over 300” Article 10 landmarks. Whole neighborhoods with large Victorian stock, such as Haight-Ashbury, Noe Valley and Eureka Valley, have no Article 10 district, so review there turns on each building’s own status.

Article 11 rarely applies to houses

Article 11 is titled for buildings and districts “in the C-3 Districts,” the downtown commercial zoning. It rates buildings in Categories I through IV and requires a Permit to Alter, minor or major, for covered work. Planning’s GIS lists seven Article 11 conservation districts, all in the Financial District or South of Market, such as Kearny-Market-Mason-Sutter and New Montgomery-Mission-Second Street.

So for a Victorian house or flat in the residential neighborhoods, Article 11 is almost never the question. If a listing describes a home as being in a “conservation district,” check the Property Information Map to see which designation is meant.

Category A, B and C: Planning’s working status

Every parcel on the Property Information Map carries a CEQA historic resource code. Planning’s draft Preservation Bulletin 16 defines them:

Category A covers resources listed on or formally found eligible for the California Register (A.1), and resources on adopted local registers or that appear eligible (A.2). They are treated as historical resources.
Category B covers properties that need further review, including buildings over 50 years old for which the city lacks a finding. Planning may ask for a Supplemental Information Form on past owners, architect and construction history, and some projects need a Historical Resource Evaluation by a qualified professional.
Category C covers properties found not to be historical resources, and those under 50 years old.

Planning’s historic resources layer held 163,287 parcel records when we queried it in October 2026: 24,481 coded A, 119,311 coded B and 19,495 coded C. A separate field adds an “A*” code for Article 10 and 11 properties; the house at 710 Steiner Street in the Alamo Square district, for example, carries both A and A*.

Planning notes that the vast majority of buildings in the city have not been surveyed, documented or listed. A “B” on a Victorian is the normal starting point, not a finding that it is or isn’t historic. Planning says CEQA review happens only when an owner applies for a building permit, so the status matters at the moment you plan work.

Permits, facades and windows

Under Planning Code section 1006, a Certificate of Appropriateness is required for construction, alteration, removal or demolition of a landmark or a structure in a historic district, and for exterior changes in a district visible from a public street where the designating ordinance requires it. Section 1005(e) exempts several kinds of work, including:

Interior-only alterations, unless they have a significant visual or material impact on the exterior.
Ordinary maintenance and repairs whose sole purpose is to correct deterioration, decay or damage. Planning’s FAQ adds that replacement materials and details must be in-kind.
Certain accessible entrances, business signs, non-visible rooftop equipment and skylights, and accessory dwelling units under section 207.2, subject to conditions.

Smaller scopes can go through an Administrative Certificate of Appropriateness reviewed by staff without a hearing. Other certificates go to a public hearing; the Historic Preservation Commission reviews changes to designated landmarks and historic districts. Article 10 designation also lets the city place a moratorium of up to one year on a demolition permit.

When a remodel counts as demolition

Section 1005(f) treats a project as demolition if it removes more than 25% of the surface of all external walls facing a public street, more than 50% of all external walls, more than 25% of external walls from their function as external or internal walls, or more than 75% of the internal structural framework or floor plates, unless the city finds that is the only feasible way to meet seismic standards. Gut renovations of old houses can cross these lines, so have your architect check the numbers early.

Windows

Planning says a building permit is required to replace windows on every building in San Francisco, historic or not. Replacements visible from the street get added review, and the Residential Design Guidelines may call for historically appropriate types such as wood sash. Category A* properties, which the window page describes as City Landmarks or properties in a conservation district, are not eligible for over-the-counter window approval and need an Administrative Certificate of Appropriateness or a Minor Permit to Alter. Planning asks owners not to buy replacement windows before checking, and recommends repair over replacement.

Renovating a historic house: the order of steps

Pull the parcel record. Look up the address on the Property Information Map for Article 10 or 11 status, district, CEQA code and past permits.
Compare permits to the house. Check the 3R report and permit history against finished basements, added units and rear additions; our guide to unwarranted units explains the risks.
Talk to the Planning counter. Ask what review your scope would get: over the counter, administrative certificate, full certificate, or a historic evaluation for a Category B building.
Design to the Secretary of the Interior’s Standards. Bulletin 16 explains that a project consistent with those standards is generally treated as mitigated for historic impacts.
Budget time. Write contingencies, and your renovation schedule, around the review path Planning describes, not around the contractor’s start date.

If you are buying a house to remodel, ask these questions during escrow. The answers can change the value of a renovation plan, which is why they matter for luxury homes as much as modest flats.

The Mills Act

Historic designation alone does not change property taxes; SF Planning says only an active Mills Act contract does. Chapter 71 of the San Francisco Administrative Code lets the city sign a preservation contract with the owner of a qualified historic property, who agrees to restore and maintain it in exchange for a lower assessment. Applications are due before May 1 each year.

Eligibility starts with designation: local Article 10 or 11, California Register or National Register. A house that is merely old or coded B does not qualify until it is designated. Contract terms, value limits and penalties are explained in our article on the Mills Act for Bay Area historic homes. If the house already has a contract, it binds you as the next owner, so read it and the maintenance plan in escrow.

Seismic retrofit of an old wood frame

Victorian and Edwardian houses are wood-frame buildings, and many sit on a raised foundation with a crawl space or short cripple walls under the first floor. California’s Earthquake Brace + Bolt program funds bolting the house to its foundation and bracing cripple walls with plywood or OSB, plus water heater strapping, for wood-frame homes built before 1980 with a raised foundation.

The standard grant is up to $3,000. The program describes higher grants for households with income of $94,480 or less, and a typical retrofit costing $3,000 to $7,000.
Grants are limited to eligible ZIP codes, ranked by earthquake hazard and the share of pre-1940 homes, and registration opens for a limited time each year. Check the program’s ZIP code list for the address.
The program describes cripple walls of 4 feet or less; ask a structural engineer how to retrofit a house outside that profile.

Larger converted Victorians can fall under the city’s mandatory soft-story program for wood-frame buildings of five or more units; our guide to seismic retrofits for multifamily buildings covers it. For liquefaction and landslide zones by address, see our San Francisco hazard maps guide.

Selling a historic home

Buyers of designated houses ask the same questions you did. Have the Property Information Map printout, any Certificates of Appropriateness and permits, a Mills Act contract and its maintenance plan, and any seismic retrofit permit ready before you list. The city’s point-of-sale items, including the 3R report and transfer tax, are summarized in our San Francisco selling requirements.

This is general information, not legal or tax advice; talk to a San Francisco land use or real estate attorney, a preservation architect, and a tax adviser about a Mills Act contract.

Questions people ask

How do I find out if a San Francisco house is historic?

Look up the address on SF Planning’s Property Information Map, which shows Article 10 and 11 status and the CEQA historic resource code. Planning notes that most buildings in the city have not been surveyed, so the code is a starting point.

What does Category B mean on the Property Information Map?

It means the building needs further review before Planning can say whether it is a historical resource. When you apply for a permit for significant work, Planning may ask for a Supplemental Information Form or a Historical Resource Evaluation by a qualified professional.

Do I need a Certificate of Appropriateness to paint or repair my house?

Not for ordinary maintenance and repairs that only correct deterioration, using in-kind materials and details. Exterior alterations to an Article 10 landmark or district building generally need one.

Can I replace the windows on a Victorian?

You need a building permit to replace windows on any San Francisco building. Street-visible windows get added review, A* properties can’t use over-the-counter approval, and Planning recommends repair over replacement.

Which San Francisco historic districts are new?

Planning’s GIS lists the Chula-Abbey Early Residential and Alert Alley Early Residential districts in the Mission, both adopted February 12, 2026.

Can I add an ADU to a house in a historic district?

Possibly. Section 1005(e) exempts accessory dwelling units under Planning Code section 207.2 from the Certificate of Appropriateness requirement, subject to conditions, so confirm how your design fits with Planning.

Does the Mills Act apply to any old house?

No. The building must be designated, locally under Article 10 or 11 or on the California or National Register, and applications are due before May 1.

If you are considering a historic house or flat, we can pull the parcel record and permit history early and help you weigh a renovation plan against what Planning is likely to allow. Contact Diamond Real Estate Group to talk about a specific property.
