Local permit rules, fees, and timelines for Covina, verified against city sources, plus the loan options NestMade matches to your equity and the rent your unit can earn.
San Gabriel Valley ADU Loans
An accessory dwelling unit adds rental income, room for family, and value to your Covina property. The local details below — each checked against its city source — shape what you can build under California's ADU law and what it costs, alongside loan options matched to your equity and timeline.
The Numbers
Covina home values support the equity an ADU loan draws on, and local rents shape whether the unit pays for itself.
The median value of owner-occupied homes in Covina is about $718,900, so most owners hold meaningful equity to borrow against.
HUD's revised FY2026 Fair Market Rent for the Los Angeles County metro, which covers Covina, is $2,079 for a studio, $2,328 for a one-bedroom, and $2,903for a two-bedroom. Fair Market Rent is HUD's 40th-percentile gross rent, so a newly built ADU often asks somewhat higher.
What You Can Build
What the city allows on a single-family lot, checked against the local ordinance and state law.
Covina caps a detached ADU at 1,000 sq ft of total floor area (CMC Ch. 17.69; ADU Ordinance No. 22-06). An attached ADU may not exceed 50% of the existing primary dwelling's floor area. A JADU is limited to 500 sq ft, contained within the walls of an existing or proposed single-family residence; an efficiency unit must be at least 220 sq ft. Note: because state law (Gov. Code 66321/66314) requires a city to permit at least 800 sq ft and at least 850 sq ft for a studio/1-BR regardless of local caps, Covina's 1,000 sq ft detached cap is the operative local maximum and exceeds the state floor.
Per ADU Ordinance No. 22-06, any ADU greater than 800 sq ft must comply with the City's adopted ADU design standards in CMC Section 17.69.040. Detached ADUs between 500 and 1,000 sq ft must submit a drainage plan (existing/proposed topography and drainage system, demonstrating no altered drainage onto neighbors). For ADUs on slopes of 4:1 or steeper or within a High/Very High Fire Hazard Severity Zone, roof material must be tile, slate, or imitation thereof; if the main house uses composition shingles the detached ADU may match, but only 40-year or higher architectural-dimension shingles are allowed. Ordinance 22-06 also adopted second-story/two-story ADU limitations: ADUs taller than 16 ft must fit within the primary residence 'buildable area' under CMC 17.14 and 17.26 residential development standards.
Covina imposes a 4-foot minimum side and rear yard setback on single-story detached ADUs; ADUs within existing structures are not subject to additional building setbacks. The City does not state a separate ADU-specific front setback in its ADU requirements; an ADU located in front of the primary dwelling would fall under the primary residence 'buildable area' and the underlying residential-zone front setback (CMC 17.14/17.26), since per state law a city cannot apply lot-coverage, FAR, or open-space standards that would prohibit an 800 sq ft, 16-ft ADU with 4-ft rear and side setbacks. No ADU-specific landscaping requirement is stated; detached ADUs of 500-1,000 sq ft must submit a drainage plan.
On a single-family lot Covina expressly allows one detached ADU combined with one JADU, i.e. two additional units (one detached ADU up to 800 sq ft plus one 500 sq ft JADU attached within the house). The City's ADU requirements describe this detached-ADU-plus-JADU combination rather than restating the full state stack. State law (Gov. Code 66323) still independently permits a homeowner to combine a state-exempt ADU, a conversion ADU, and a JADU on a single-family lot; Covina processes ADUs ministerially consistent with state law. For multifamily lots, Covina allows conversion ADUs equal to 25% of existing units (or one, whichever is greater) OR up to two detached ADUs, but not both.
Costs
What the city and school district charge, and where ADUs get a break.
Covina's current Planning Division fee schedule prices ADU planning review as a Site Plan Review (SPR) Minor: $837.00 for an ADU of 801 to 1,000 sq ft, and $200.00 for an ADU under 800 sq ft (which also covers preparation of the required covenant agreement). These tiers took effect 7/1/25 and replace the obsolete $3,168 figure from the 2017 schedule (Resolution 16-7554); ADUs are carved out of the general SPR-Minor tier. The schedule also charges a General Plan Fee of $2.50 per $1,000 of construction valuation. Building plan-check and permit fees are valuation-based and invoiced at submittal, not a flat ADU figure. Per the Residential ADU handout, a recorded covenant is required before permit issuance (covenant agreement fee $105.00 per Ord. 22-06), a separate ADU address must be requested before plan-check ($395.00 administrative fee), and development impact fees apply before occupancy.
Per CMC 17.69.040(I)(2), Covina does not charge development impact fees on an ADU under 750 sq ft (projects proposing more than one ADU each under 750 sq ft, but combining to 750 sq ft or more, also do not trigger fees). ADUs 750 sq ft or larger pay impact fees charged proportionally to the square footage of the primary dwelling unit (ADU SF / primary unit SF x primary unit fee, rounded to two decimals), and the ADU fee can never exceed the primary unit's fee; if the ADU equals or exceeds the primary unit's size, the full primary-unit fee applies. The City's impact fee schedule was adopted by Council Resolution 2024-057 on July 16, 2024 (projects entitled under the prior 2005 schedule before September 16, 2024 are unaffected), and is adjusted automatically each July by the ENR Construction Cost Index for the Los Angeles region. The schedule's residential per-dwelling-unit totals (Table S.2, including the 0.6% administrative charge) drive the proportional ADU calculation: $13,075/DU for a 600-800 sq ft primary unit and $18,087/DU for a >800-1,200 sq ft primary unit (other tiers: <600 sq ft $10,116; >1,200-1,900 sq ft $24,527; >1,900-2,300 sq ft $30,501; >2,300 sq ft $35,398). Covina is served by three unified school districts - Charter Oak, Azusa, and Covina-Valley; the City directs the ADU owner to obtain a School Clearance and pay the statutory developer fee for added habitable space to the district covering the parcel before permit issuance.
Process
How long it takes, and the shortcuts the city offers.
No pre-approved or standard ADU plan set is published by the City of Covina as of June 2026. The City's ADU pages and ADU packet describe a custom plan-submittal process (applicant-prepared site plan, floor plan, and elevations reviewed by Planning then Building & Safety) and reference no AB 1332 pre-approved-plan catalog or online listing. AB 1332 (Gov. Code 65852.27, eff. Jan 1, 2025) requires cities to accept and post applicant-submitted pre-approved ADU plans on request, but Covina has not published a standard-plan program.
Covina's ADU process is sequential: (1) Planning first - submit the ADU Application, ADU Checklist, deed/title report, and site plan/floor plan/elevations to Planning-Submittal@covinaca.gov (or in person); Planning issues an Approval-Clearance, allow 15-30 days. (2) Building & Safety plan check - integrate the stamped Planning approval as a conditions-of-approval sheet, then submit hard-copy plans (4 sets for new detached ADUs; 3 sets for JADUs/conversions) with Title-24, structural calcs, and a soils report as applicable; first review takes about 4-6 weeks, with about 2 weeks per re-submittal. (3) Prior to permit issuance: recorded covenant agreement (Ord. 22-06), School Clearance, LA County Sanitation District clearance, environmental/BMP forms, and (if required) LA County Fire clearance/water-flow test. (4) Prior to building final/CofO: solar permit if required, and impact fees for ADUs 750 sq ft or larger. A separate ADU address must be requested before plan-check submittal (IB-05 form). Covina does not document a formal expedited/fast-track ADU review track.
Watch-outs
A few local specifics that can affect where and whether you build.
Yes for fire: Covina has formally designated a Very High Fire Hazard Severity Zone within the city under CMC Chapter 14.13, shown on the official map 'City of Covina FHSZ, Tile 1' on file with the City Clerk, adopted per Gov. Code 51179 and recommended by CAL FIRE/OSFM. ADUs sited on slopes of 4:1 or steeper or within a High/Very High FHSZ trigger added requirements: Planning plus LA County Fire Department review, a minimum 10-foot defensible-space zone, wildland-urban-interface construction (CBC/CRC), and tile/slate/imitation roofing (or 40-year+ architectural composition shingles). Historic: Covina adopted a Historic Preservation Ordinance (1997) but, per its own framework, the City has not designated any landmarks or a formal historic-overlay district; the downtown is documented only by the 2007 Covina Town Center Historic Resource Survey, so no historic-district designation currently imposes ADU-specific restrictions.
Covina is served by a public sanitary sewer system, not septic. The City operates and maintains its own sewer collection system (Municipal Code Title 13, Chapter 13.50, 'Sanitary Sewers and Industrial Waste'), and lies within the Los Angeles County Sanitation Districts service area; local laterals connect to LACSD trunk sewers. The city requires a Sanitation Clearance / LACSD connection-fee application for any ADU that adds bedrooms or bathrooms, confirming sewer connection as the standard path. No official source identifies any neighborhood within the incorporated city on septic — the developed valley-floor city is on public sewer, so a typical ADU connects to the existing sewer and no percolation test is triggered. (Septic/OWTS use tied to the 'Covina' mailing address occurs only in surrounding unincorporated LA County pockets governed by the County Department of Public Health, outside city jurisdiction.)
No. No City of Covina ordinance opting into AB 1033 (Gov. Code 65852.26 separate sale/conveyance of an ADU as a condominium) was located as of June 2026. To the contrary, Covina requires a recorded covenant agreement on every ADU (Ord. 22-06) and a deed restriction prohibiting separate conveyance of a JADU, which is consistent with not having opted into AB 1033. AB 1033 is opt-in only; without a local adopting ordinance, ADUs in Covina cannot be sold separately from the primary dwelling.
