In a newer planned community, the cost of owning is built in layers, and only the first is limited by Proposition 13. This page separates them so the monthly figure on a listing does not surprise you.
Property Tax Explained
Prop 13 and Mello-Roos in Ocean View Hills
How the base tax, voter-approved charges, special taxes and HOA dues stack up in a newer community like Ocean View Hills, with a monthly worked example.
The layers
- The base property tax. Proposition 13 sets it at 1% of assessed value and limits yearly increases in the assessed value to inflation or 2%, whichever is less. When a home is sold, the assessor sets a new value at the purchase price.
- Voter-approved charges. Bonds and similar measures are added to the 1%.
- Special taxes such as Mello-Roos. The San Diego County Assessor explains that a special tax is levied by a community facilities district to pay for facilities in an area. It appears on the annual property tax bill, is set by the district rather than by the property’s value, and is not subject to Proposition 13’s limits. Newer communities often have one, and it can last for decades.
- Homeowners association dues. Not a tax, but a monthly cost that pays for shared amenities, landscaping, insurance and, in townhome communities, sometimes exteriors.
Ask for the exact figures for a specific home. They are on the tax bill, in the association documents and in the seller’s disclosures.
Worked example
How the layers add up
A monthly picture at today’s typical value in ZIP 92154, with hypothetical special-tax and dues figures.
What sits on top of the mortgage
Assumes $750,299 (the typical home value in ZIP 92154, Aug 2026), 20% down, a 30-year fixed loan at 7.28% (Freddie Mac), tax at 1.15%, insurance at 0.30% of the price, and, as hypothetical figures, a special tax of $2,400 a year and HOA dues of $250 a month. Yours will differ; the point is the stacking.
| Layer | Per month | Running total |
|---|---|---|
| Principal and interest | $4,107 | $4,107 |
| Base property tax and voter-approved charges (1.15%) | $719 | $4,826 |
| Homeowners insurance | $188 | $5,014 |
| Special tax (Mello-Roos, hypothetical) | $200 | $5,214 |
| HOA dues (hypothetical) | $250 | $5,464 |
In this illustration the special tax and dues add about $450 a month, or 9% on top of the payment, tax and insurance. That is why the monthly figure, not the price, is the fair way to compare a home in a planned community with one outside it.
What to ask for, and when
- The district and the amount. Which community facilities district applies, what the annual charge is, and whether it increases on a schedule.
- How long it lasts. The end date of the special tax, and whether it can be paid off early.
- The association budget and reserve study. What dues cover and how much is held in reserve.
- Recent minutes. Planned or past special assessments.
- When to ask. Before your inspection period ends, so you have time to review the answers.
The article on HOAs, Mello-Roos and assessments and the owner’s guide cover the same ground from the buyer’s side.
Worked example
The base tax over ten years
The 1% layer at today’s typical value, with the assessed value at the 2% cap.
The base tax, ten years out
Illustration: buy at $750,299 (the typical home value in ZIP 92154, Aug 2026). Tax is figured at 1.15% of value. Column two follows the 2% ceiling on yearly increases; column four follows a market that grows 4% a year. These are not forecasts.
| Point in time | Assessed value | Property tax | Market value (4% growth) | Tax if bought then | Difference in value |
|---|---|---|---|---|---|
| Year 1 | $750,299 | $8,628 | $750,299 | $8,628 | $0 |
| Year 2 | $765,305 | $8,801 | $780,311 | $8,974 | $15,006 |
| Year 3 | $780,612 | $8,977 | $811,524 | $9,333 | $30,912 |
| Year 5 | $812,148 | $9,340 | $877,744 | $10,094 | $65,596 |
| Year 10 | $896,677 | $10,312 | $1,067,910 | $12,281 | $171,233 |
Expect about $8,628 in the first year ($719 monthly) on $750,299. By year 10 the capped bill would be about $10,312, against about $12,281 for a new buyer at the then market value. Mello-Roos, exemptions and temporary reductions would change these figures.
Common questions
Does the 2% cap apply to Mello-Roos?
No. Special taxes are set by the district and are not limited by Proposition 13.
Will the special tax appear on the seller’s tax bill?
Yes, if the property is in the district. The bill shows it as a separate line.
Does the homeowners’ exemption reduce it?
The exemption reduces the assessed value by $7,000 for a home you live in. It does not reduce special taxes, which are not based on assessed value.
