Local review conditions
What sets a Pomona project apart.
These are the conditions on record for Pomona. Each one changes the design, the studies or the agencies involved — and each one still has to be confirmed for the exact parcel.
Historic resources and districts
A designated resource or a contributing property in a district changes what can be demolished, how additions read from the street, which materials are acceptable and what documentation the file needs.
VerifyCheck whether the property is designated or a district contributor, which review applies to exterior change and demolition, and what documentation is expected.
Residential and mixed-use districts
A parcel two streets apart can sit in a residential district or a mixed-use one, and the two follow different standards for height, parking, ground-floor use and review path.
VerifyConfirm the exact zoning district and any specific-plan or overlay assigned to the address before assuming a residential path.
Established-block infill
On a built-out block, the constraints are the neighbours: existing structures, side-yard distances, window-to-window privacy, utility locations, driveway aprons and the street's rhythm of massing.
VerifyConfirm the zoning district's setbacks and lot coverage, locate existing utility connections and easements, and pull the permit history for the existing structures.

Local detailPomona's ADU section (PZDC § 830.A) is mid-revision: HCD found the 2022 Ordinance 4324 non-compliant with state ADU law in an October 2024 letter, and Ordinance 4363 was still listed for second reading on the 26 Jan 2026 council agenda. Ask the Planning Division which version governs your application date.

Recommended reading
What to read before deciding in Pomona.
Start with the parcel, not the city
Pomona sits roughly 28.1 miles east of Downtown Los Angeles, within the San Gabriel Valley group. Even so, the rules that decide a project are assigned by address: zoning district, overlays and mapped conditions. Confirm those three on pomonaca.gov before any drawing is commissioned.
Historic resources and districts
A designated resource or a contributing property in a district changes what can be demolished, how additions read from the street, which materials are acceptable and what documentation the file needs. Check whether the property is designated or a district contributor, which review applies to exterior change and demolition, and what documentation is expected.
Residential and mixed-use districts
A parcel two streets apart can sit in a residential district or a mixed-use one, and the two follow different standards for height, parking, ground-floor use and review path. Confirm the exact zoning district and any specific-plan or overlay assigned to the address before assuming a residential path.
Established-block infill
On a built-out block, the constraints are the neighbours: existing structures, side-yard distances, window-to-window privacy, utility locations, driveway aprons and the street's rhythm of massing. Confirm the zoning district's setbacks and lot coverage, locate existing utility connections and easements, and pull the permit history for the existing structures.
Compare with the neighbouring jurisdictions
The closest incorporated cities are La Verne, Claremont, Diamond Bar. Each publishes its own ordinance and its own review process, so experience in one of them does not predict requirements or timing in Pomona. Read the ordinance of the city that actually issues the permit.
Read the state statute alongside the local ordinance
State accessory-dwelling and two-unit statutes set the framework; the Pomona ordinance applies that framework locally; and the building standards edition in effect at submittal decides what can be built. All three layers are read together, and it is the current edition that governs.
Municipal services
Banks, licences, payments and records in Pomona.
RSA takes no referral fees for recommending banks, lenders or vendors, and names none. Below is the service type, the rule that governs it and the official office where it is verified — plus Pomona's own fee and records sources.
Financing: banks and lenders
Home equity line or loan
Draws on equity already built up in the existing house. Compare rate, term, closing costs and whether the rate is variable before signing — terms are set by the lender, not by the city.
Cash-out refinance or construction loan
A refinance replaces the existing mortgage; a construction loan releases funds in stages against verified progress. Both depend on appraisal, income and the approved project scope.
Verify the licence of whoever offers the loan
Mortgage lenders and loan officers are publicly registered. Check the register before sharing financial documents or paying any upfront fee.
Effect on property tax
New construction can trigger an added assessment on what was built. The framework is published by the state; the actual assessment for a parcel is made by the county assessor.
Project payments: deposits, fees and control
Statutory deposit limit in a home improvement contract
California law limits the down payment on a home improvement contract; the exact wording and its exception are read in the code and in the licence board's own guidance.
Verify licence and bond before the first payment
A contractor's licence, its status and the bond are public. Check them by licence number, not by the trade name printed on a proposal.
Permit and plan-check fees
Each city publishes and updates its own fee schedule. Confirm the current schedule with the city that issues the permit — another city's figure is not a reference.
Obtaining documents and records
Parcel and assessment data
Parcel number, recorded ownership and stated characteristics — the starting point of any feasibility study.
Deeds, easements and recorded maps
County recorded documents show easements, restrictions and earlier divisions that can decide where building is possible at all.
Permit history and building records
Earlier permits on the existing house explain what is legalised. They are requested from the city that issued the original permit.
Hazard maps that apply to the parcel
Flood, fire hazard severity and geologic hazards are checked by address in the official sources, not by neighbourhood impression.
Payments and financing
How a project is paid for and financed in Pomona.
Payments and fees
Statutory limit on the first payment
On a California home-improvement contract the down payment may not exceed $1,000 or 10 percent of the contract price, whichever is less. Later payments must follow work actually completed.
California Business & Professions Code section 7159.5Verify the licence and bond before paying
Check the contractor licence status, classification, bond and workers compensation on the state licence board record before any money changes hands.
Contractors State License BoardPermit and plan-check fees in Pomona
Pomona publishes its own permit, plan-check and impact fees, and school or utility charges may be collected separately. Confirm the current schedule with the city before budgeting.

Financing
Confirm any lender is licensed
Home-equity lines, cash-out refinances and construction loans are the common routes. Look up any lender or loan officer in the national licensing registry before sharing documents.
NMLS Consumer AccessHow the project affects your assessment
New construction is generally assessed on the value added by the new work rather than reassessing the whole property. The county assessor publishes how new construction is handled.
