Anaheim Home Remodeling

60.7 percent of Anaheim homes were built between 1950 and 1979

Of Anaheim's 110,705 housing units in the 2020 to 2024 Census count, 67,193 were built across those three decades: 24,704 in the 1950s, 16,902 in the 1960s and 25,587 in the 1970s. The median year built is 1973, and only 2.4 percent of homes predate 1940. A tract house from this period may still have original supply lines, an original electrical panel and single-pane windows, and paint applied before 1978 can contain lead. Open a wall and those items can join the scope, so hold some of the budget back for them.

East Anaheim's hills carry fire zones and a landslide record

The city says the wildfire threat is highest in east Anaheim, where the foothills of the Santa Ana Mountains are moderately to steeply sloped, and Cal Fire redrew the hazard zones in spring 2025. The same slopes have moved before. The city's general plan review recounts the 1993 Santiago Landslide, which destroyed more than 30 homes in east Anaheim Hills and affected over 200 other structures, and the 2005 Ramsgate Landslide, which destroyed three homes and a private street. On a hillside lot, budget for a soils report and drainage work before an addition or a pool, and ask the city's wildfire mitigation specialist about rebates for fire-resistant upgrades.

Anaheim tracks more than 1,400 historic properties

The city's local inventory lists over 1,400 historic properties, most of them inside four districts that together cover two square miles of central Anaheim: Anaheim Colony, the city's first and largest, plus Five Points, the Historic Palm District and Hoskins, which dates from right after World War II. When the owner of a listed house applies for a building permit, preservation staff review the plans and send recommendations, which the owner may follow or not. A demolition permit waits for a 60-day notice of intent to demolish. Owners who restore and keep the exterior can apply for a Mills Act contract, which lowers property taxes, with no application fee.

How much does a bathroom remodel cost in Anaheim?

Among Anaheim single-family permits from 2025, the 138 that mention a bathroom carried a median declared value of $12,000. That number comes from the application, not the final invoice. Metro-wide, the 2023 American Housing Survey puts the typical bathroom remodel at $8,727, and that figure also counts small refreshes and work owners did themselves.

Which Anaheim remodeling projects need a permit?

Most of them. The city says most improvements need a permit from its Building Division before construction starts, and only cosmetic work is exempt. Rooftop solar, EV chargers and panel upgrades on single-family homes can be permitted online. Other projects go through plan submittal, and historic homes also get a review from preservation staff.

How many reroof permits does Anaheim issue?

In 2025 the city issued 675 reroof permits for single-family homes, making reroofing the most common house project after trade-only permits. Half of the 642 that listed a value came in at $13,000 or less. A reroof needs a permit from the Anaheim Building Division, and a listed historic house also gets a look from preservation staff.

Is my Anaheim house historic?

It may be. Anaheim keeps an inventory of more than 1,400 historic properties, most of them in the Anaheim Colony, Five Points, Historic Palm and Hoskins districts in central Anaheim. A listed home gets plan comments from preservation staff when you apply for a building permit, and it may qualify for a Mills Act property tax contract.

Can I build an ADU in Anaheim?

Yes. Anaheim issued building permits for 266 ADU units in 2025. The city offers pre-approved plans, and its ADU Express program can complete review of a pre-approved detached ADU in 1 to 3 days on a qualifying single-family lot. A junior ADU must sit inside the house and needs an owner-occupancy deed restriction.
